Description

Defecation pad using peat moss and device for manufacturing the same {Defecation pad using peat moss and device for manufacturing the same}

The present invention relates to a diaper pad using peat moss and a manufacturing device therefor, and more specifically, to a diaper pad using peat moss having a novel structure in which a peat moss coating layer having a sterilizing and deodorizing function is formed on a highly absorbent polymer layer of the diaper pad, and a device for manufacturing the same.

In general, pets raised at home are induced to defecate in the same place due to the animal's nature or training, and a separate pee pad is placed in the induced place to absorb moisture and clean the pet's excrement.

Typically, conventional pet pee pads are composed of an anti-slip pad layer made of synthetic resin, which is a type of waterproof paper with anti-slip and excrement waterproofing functions, an embossed pulp layer laminated on the anti-slip pad layer to form the base layer of the pee pad, a superabsorbent polymer layer laminated on the pulp layer to absorb and adsorb excrement, and a cover layer made of nonwoven fabric laminated on the superabsorbent polymer layer.

However, conventional diaper pads have the following problems:

The above super absorbent polymer layer (SAP, Super Absorbent Polymer) functions to absorb and adsorb excrement such as urine and prevent excrement from overflowing from the diaper pad. However, if the thickness of the super absorbent polymer layer is simply increased to increase the excrement absorption performance, there is a problem that the manufacturing cost increases significantly because the super absorbent polymer layer is expensive. On the other hand, if the thickness of the super absorbent polymer layer is applied thinly, the excrement absorption performance inevitably decreases, which is the problem.

In addition, the superabsorbent polymer layer simply has the function of absorbing and adsorbing urine and other excrement, and has the disadvantage of not being able to remove odors such as ammonia contained in excrement.

Moreover, even if the high-absorbent polymer layer and pulp layer of the conventional pee pad absorb and adsorb the excrement of the pet, there is a problem in that as the number of times of excrement increases, the excrement accumulates, and accordingly, the foul odor due to the smell of ammonia contained in the excrement becomes worse.

Of course, there are existing charcoal-based pee pads that eliminate odors, but they do not last long and leave a strong urine smell, making them difficult to use repeatedly.

In addition, the superabsorbent polymer layer causes itchiness in pets due to chemicals, and as a type of plastic biodegradable film, it takes about 100 to 500 years to decompose, so there is a problem that it is not environmentally friendly.

In addition, some of the conventional pee pads contain pee inducers in their superabsorbent polymer layers. These pee inducers contain harmful substances such as benzophenone, toluene phthalate, and artificial fragrances, which can penetrate the pet's skin and cause inflammation.

In addition, some conventional pee pads contain fluorescent whitening agents, which are dyes that make the pee pad surface look clean. However, these fluorescent whitening agents also contain formaldehyde, a carcinogen, which can cause allergies, dermatitis, and other skin diseases in pets.

In addition, the present invention provides a manufacturing device for a diaper pad using peat moss, which applies a peat moss coating layer that blocks the volatilization of excrement on a highly absorbent polymer layer of a diaper pad, thereby preventing the emission of odor and performing functions such as rapid drying and sterilization of excrement, and allows the peat moss coating layer to be applied with a uniform distribution and thickness on the highly absorbent polymer layer.

It is characterized in that a second pulp layer with an embossing structure that blocks the detachment of peat moss particles and acts as a buffer is further bonded between the peat moss coating layer and the dry cover layer.

In order to achieve the above object, another embodiment of the present invention provides a diaper pad manufacturing device using peat moss, characterized by comprising: a diaper pad primary manufacturing device which sequentially laminates and mutually bonds an anti-slip film layer made of a synthetic resin material having anti-slip and waterproof functions, a first pulp layer having an embossed structure that forms a base layer of a diaper pad and assists in cushioning and excrement absorption, and a superabsorbent polymer layer that absorbs and adsorbs excrement; an adhesive spray nozzle which applies an eco-friendly adhesive on the superabsorbent polymer layer of a diaper pad discharged from the first manufacturing device; a peat moss coating layer forming device which sprays and adheres peat moss particles on the superabsorbent polymer layer to which the eco-friendly adhesive has been applied, thereby forming a peat moss coating layer; and a diaper pad secondary manufacturing device which bonds a dry cover layer covering the peat moss coating layer of a diaper pad discharged from the peat moss coating layer forming device to the edge of the superabsorbent polymer layer.

The above diaper pad primary manufacturing device is characterized by comprising: a first winding roller having the anti-slip film layer wound around it; a second winding roller having the first pulp layer wound around it; a third winding roller having the superabsorbent polymer layer wound around it; a first press roller for sequentially stacking and pressing an anti-slip film layer pulled out from the first winding roller, a first pulp layer pulled out from the second winding roller, and a superabsorbent polymer layer pulled out from the third winding roller; and a first heat bonding device for applying heat to each edge portion of the anti-slip film layer, the first pulp layer, and the superabsorbent polymer layer, which are sequentially stacked through the first press roller, and for thermally bonding them.

Through the means for solving the above-mentioned problem, the present invention provides the following effects.

First, by applying a peat moss layer to the highly absorbent polymer layer of the pee pad, the volatilization of excrement is blocked, preventing odor from being emitted, and the peat moss particles can provide functions such as rapid drying and sterilization of excrement.

Moreover, the peat moss particles that make up the peat moss coating layer are acidic with a pH of 3 to 4, which is found in urine. It has an excellent odor reduction effect by reducing ammonia (NH3), and can be disposed of in an environmentally friendly manner by using biodegradable materials rather than plastic decomposable films, so it can provide environmentally friendly advantages.

Second, since the peat moss layer is applied and adhered with a uniform distribution and thickness using an eco-friendly adhesive on the superabsorbent polymer layer, the phenomenon of the peat moss particles moving out of their original position and gathering on one side can be prevented.

Third, by bonding a peat moss coating layer on a superabsorbent polymer layer with an eco-friendly adhesive with a uniform distribution and thickness, and then bonding a second pulp layer to block external detachment of the peat moss coating layer before laminating and attaching a dry cover on the superabsorbent polymer layer, the phenomenon of peat moss particles leaking out of the pee pad can be completely prevented.

Fourth, the second pulp layer with dry cover and buffering function can alleviate pets' aversion to peat moss particles.

Fifth, by absorbing some of the pet's excrement in the peat moss layer, the amount of expensive superabsorbent polymer layer can be reduced, thereby reducing the manufacturing cost of the pee pad.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

The attached drawing 1 is an exploded perspective view illustrating a pee pad using peat moss according to one embodiment of the present invention, and drawing 2 is a cross-sectional view illustrating a pee pad using peat moss according to one embodiment of the present invention.

As shown in FIG. 1 and FIG. 2, an anti-slip film layer (11) is positioned at the bottom of the diaper pad (10). This anti-slip film layer (11) is made of a synthetic resin material that is non-slip and has a waterproof function.

Accordingly, the anti-slip film layer (11) is made of a waterproof material, so it can prevent the pet's urine from leaking out, and as it is made of a non-slip material, it can prevent the pee pad from slipping out of place, thereby preventing strain on the pet's hip joint.

On top of the above anti-slip film layer (11), a first pulp layer (12) with an embossing structure that forms the base layer of the diaper pad (10) and assists in cushioning and excrement absorption is laminated and bonded.

Accordingly, the first pulp layer (12) can buffer and disperse the load of a pet that has climbed onto the pee pad, and can auxiliary absorb some of the remaining amount of excrement that is mostly absorbed by the superabsorbent polymer layer (13) and peat moss coating layer (14) described later.

On top of the first pulp layer (12), a super absorbent polymer layer (13, SAP: Super Absorbent Polymer) that absorbs and adsorbs most of the pet's excrement is laminated and bonded. This super absorbent polymer layer (13) can be manufactured to a predetermined thickness using polyacrylic acid hydrogel.

Accordingly, the superabsorbent polymer layer (13) functions to absorb and adsorb most of the pet's excrement (urine) and prevent the excrement from overflowing from the excrement pad.

In particular, a peat moss layer (14) that performs the functions of blocking, drying, and sterilizing odor of excrement is applied and adhered on top of the superabsorbent polymer layer (13).

The above peat moss is a compound word of peat and moss, and refers to organic matter that has been deposited in cold wetlands for thousands to tens of thousands of years, and is natural organic matter in which moss, aquatic plants, reeds, trees, etc. have undergone biochemical changes and retain the original plant tissue.

The above peat moss is acidic with a pH of 3.5 to 4.5, has a moisture absorption rate of up to 16 to 20 times its unit weight, and converts the absorbed moisture into volatile acid and evaporates it into the atmosphere, thereby exhibiting a quick drying function and providing deodorizing, sterilizing, and antibacterial functions. Due to these characteristics, it is used in various products such as a tropical ornamental fish water quality improvement agent, horticultural soil, sawdust substitute, eco-friendly flooring material, insulation material, and soap.

Preferably, the peat moss coating layer (14) is applied on the superabsorbent polymer layer (13) with a thickness of 0.1 mm to 1.5 mm. The reason for this is that if it is less than 0.1 mm, the odor blocking, drying, and sterilizing functions of excrement are minimal, and if it exceeds 1.5 mm, the excrement absorption and adsorption functions of the superabsorbent polymer layer (13) are reduced.

At this time, the peat moss coating layer (14) is made of peat moss particles, and the peat moss particles should be evenly dispersed on the surface of the superabsorbent polymer layer (13) and adhered and fixed to prevent them from gathering to one side.

To this end, a type of eco-friendly adhesive (16), water-based glue, is first sprayed onto the superabsorbent polymer layer (13) in a fine thickness, peat moss particles are evenly sprayed onto the superabsorbent polymer layer (13), and then the peat moss particles are pressed onto the surface of the superabsorbent polymer layer (13) with the eco-friendly adhesive (16) in between, thereby forming a peat moss coating layer (14) that is pressed onto the superabsorbent polymer layer (13) in a uniform thickness and is adhesively fixed.

Accordingly, by forming a peat moss coating layer (14) with excellent absorbency and moisture retention on the surface of the superabsorbent polymer layer (13), the functions of drying, absorbing and adsorbing excrement can be easily achieved together with the superabsorbent polymer layer, and the amount of ammonia generated from urine can be reduced by utilizing the acidic pH of peat moss (3-4), thereby reducing odor, and the manufacturing cost of the diaper pad can be reduced by reducing the thickness of the expensive superabsorbent polymer layer.

A dry cover layer (15) made of non-woven fabric is laminated on top of the above peat moss coating layer (14). This dry cover layer (15) is made of non-woven fabric and covers the above peat moss coating layer (14), and is laminated and bonded to the edge of the above superabsorbent polymer layer (13).

Accordingly, the above-mentioned dry cover layer (15) is made of a non-woven material, so it instantly absorbs excrement and prevents excrement such as urine from being stained on the pet's feet, dries the outermost surface of the excrement pad quickly, and in particular, has the function of blocking the peat moss particles constituting the peat moss coating layer (14) from leaking out to the outside.

Meanwhile, as another embodiment of the present invention, as shown in the attached FIGS. 3 and 4, a second pulp layer (17) with an embossing structure may be further bonded between the peat moss coating layer (14) and the dry cover layer (15).

In detail, the second pulp layer (17) may be laminated to cover the peat moss coating layer (14) and further bonded to the edge of the superabsorbent polymer layer (13), and then the dry cover layer (15) may be laminated and bonded on top of the second pulp layer (17).

Accordingly, the second pulp layer (17) not only functions to buffer and distribute the load of a pet that has climbed onto the pee pad, but also double-blocks the external detachment of the peat moss particles forming the peat moss coating layer (14) together with the dry cover layer (15), thereby completely preventing and protecting the external detachment of the peat moss particles.

Here, the device for manufacturing the diaper pad of the present invention having the above-described laminated structure is as follows.

The attached Fig. 5 is a side cross-sectional view illustrating a manufacturing device for a diaper pad using peat moss according to the present invention in succession by process, Fig. 6 is a side cross-sectional view illustrating a device for laminating and attaching a second pulp layer to a secondary manufacturing device for a diaper pad using peat moss according to the present invention, and Fig. 7 is a perspective view illustrating a peat moss coating layer forming device of the manufacturing device for a diaper pad using peat moss according to the present invention.

The diaper pad manufacturing device (100) of the present invention is configured to include a diaper pad primary manufacturing device (110), an adhesive spray nozzle (120), a peat moss coating layer forming device (130), and a diaper pad secondary manufacturing device (140).

The above-mentioned diaper pad primary manufacturing device (110) can be configured to sequentially laminate and mutually bond an anti-slip film layer (11) made of synthetic resin material having anti-slip and waterproof functions, a first pulp layer (12) having an embossed structure that forms the base layer of the diaper pad and assists in cushioning and excrement absorption, and a superabsorbent polymer layer (13) that absorbs and adsorbs excrement.

To this end, the first manufacturing device for the diaper pad (110) includes a first winding roller (111) on which the anti-slip film layer (11) is wound, a second winding roller (112) on which the first pulp layer (12) is wound, and a third winding roller (113) on which the superabsorbent polymer layer (13) is wound.

In addition, the above-mentioned diaper pad primary manufacturing device (110) is configured to include a pair of primary pressurizing rollers (114) that laminate and pressurize an anti-slip film layer (11), a first pulp layer (12), and a superabsorbent polymer layer (13) and guide them to a first heat-bonding device (115), and a first heat-bonding device (115) that applies heat to the laminated anti-slip film layer (11), the first pulp layer (12), and the superabsorbent polymer layer (13) to mutually thermally bond them.

Accordingly, the anti-slip film layer (11) pulled out from the first take-up roller (111), the first pulp layer (12) pulled out from the second take-up roller (112), and the superabsorbent polymer layer (13) pulled out from the third take-up roller (113) sequentially enter a pair of primary pressure rollers (114), so that the anti-slip film layer (11), the first pulp layer (12), and the superabsorbent polymer layer (13) can be laminated and pressed by the pair of primary pressure rollers (114) and guided to the first heat bonding device (115).

Accordingly, by applying heat from the first heat bonding device (115) to the edges of the anti-slip film layer (11), the first pulp layer (12), and the superabsorbent polymer layer (13) that are sequentially laminated through the first pressure roller (114) and thermally bonding them, the anti-slip film layer (11), the first pulp layer (12), and the superabsorbent polymer layer (13) can be mutually bonded in a laminated state.

The above adhesive spray nozzle (120) is positioned to apply an eco-friendly adhesive (16) on the highly absorbent polymer layer (13) of the diaper pad discharged from the first thermal bonding device (115) of the diaper pad primary manufacturing device (110).

Preferably, the adhesive spray nozzle (120) may be configured to spray a type of water-based adhesive (16) onto the surface of the superabsorbent polymer layer (13), but spray at a concentration and in an amount that does not prevent urine, etc. from being absorbed into the superabsorbent polymer layer (13).

Accordingly, when the highly absorbent polymer layer (13) of the diaper pad discharged from the first thermal bonding device (115) of the diaper pad primary manufacturing device (110) passes by, the eco-friendly adhesive (16) can be evenly sprayed onto the surface of the highly absorbent polymer layer (13) from the adhesive spray nozzle (120), thereby preventing the phenomenon of the peat moss particles moving out of their original position and gathering to one side as they are fixed by the eco-friendly adhesive.

Next, the diaper pad with the eco-friendly adhesive (16) applied to the surface of the superabsorbent polymer layer (13) enters the peat moss forming device (130).

The above peat moss coating layer forming device (130) is configured to spray and adhere peat moss particles onto the highly absorbent polymer layer (13) to which the eco-friendly adhesive (16) is applied.

To this end, the peat moss coating layer forming device (130) may be configured to include a sieve drum (131) having a mesh structure in which a predetermined amount of peat moss is stored and the peat moss is discharged and sprayed by centrifugal force or vibration force, as shown in FIGS. 5 and 7, a motor (132) connected to one end of the sieve drum (131) so as to be able to apply rotational force, and a bearing (133) connected to the other end of the sieve drum (131) so as to be able to support rotation.

Accordingly, when the diaper pad manufactured in the above diaper pad primary manufacturing device (110) passes through the adhesive spray nozzle (120) and the bottom of the sieve drum (131), the peat moss particles discharged from the inside of the sieve drum (131) when the sieve drum (131) rotates due to the driving of the motor (132) can be easily sprayed on the surface of the superabsorbent polymer layer (13) to which the eco-friendly adhesive (16) is applied.

Preferably, the sieve drum (131) is provided with a vibration generating means, although not shown, so that by applying vibration force when the sieve drum (131) rotates, the peat moss particles inside the sieve drum (131) can pass through the mesh of the sieve drum by the centrifugal force and vibration force of the sieve drum (131) and be evenly sprayed on the surface of the superabsorbent polymer layer (13) to which the eco-friendly adhesive (16) is applied.

In addition, the peat moss coating layer forming device (130) may be configured to further include a collection tank (135) disposed at a lower position of the sieve drum (131), as shown in FIGS. 5 and 7, for collecting peat moss particles that are discharged from the inside of the sieve drum (131) and fall without being sprayed on the superabsorbent polymer layer (13) so that they can be recycled.

Accordingly, when the peat moss particles inside the sieve drum (131) pass through the mesh of the sieve drum by the centrifugal force and vibration force of the sieve drum (131) and are evenly sprayed on the surface of the superabsorbent polymer layer (13) to which the eco-friendly adhesive (16) is applied, some of the peat moss particles that are not sprayed can be collected by falling into the collection container (135) so that they can be reused.

In addition, the peat moss coating layer forming device (130) may further include a pair of secondary pressure rollers (134) arranged at the discharge position of the sieve drum (131), as shown in FIGS. 5 and 6, to press the peat moss particles sprayed on the superabsorbent polymer layer (13) to a uniform thickness and bond them together using an eco-friendly adhesive.

Accordingly, the peat moss particles are evenly sprayed on the surface of the superabsorbent polymer layer (13) to which the eco-friendly adhesive (16) is applied, and then, when passing through the second pressure roller (134), they can be pressed to a uniform thickness and fixed in an adhesive manner, thereby forming a peat moss coating layer (14) on the superabsorbent polymer layer (13).

In this way, by forming a peat moss coating layer (14) on the highly absorbent polymer layer (13) of the diaper pad, the volatilization of excrement is blocked, preventing odor from being emitted, and the peat moss particles can provide rapid drying and sterilization functions for excrement. Furthermore, the peat moss particles constituting the peat moss coating layer (14) are acidic with a pH of 3 to 4, which is present in urine. It has an excellent odor reduction effect by reducing ammonia (NH3), and can be disposed of in an environmentally friendly manner by using biodegradable materials rather than plastic decomposable films, so it can provide environmentally friendly advantages.

Next, the defecation pad (100) discharged from the peat moss coating layer forming device (130), that is, the defecation pad with the peat moss coating layer (14) formed on the superabsorbent polymer layer (13), is directed to the defecation pad secondary manufacturing device (140).

One embodiment of the above-described secondary manufacturing device (140) for the diaper pad, as illustrated in FIG. 5, is a device for bonding a dry cover layer (15) covering the peat moss coating layer (14) to the edge of a superabsorbent polymer layer (13), and may include a fourth take-up roller (141) around which the dry cover layer (15) is wound, a pair of third press rollers (142) that pressurize and laminate the dry cover layer (15) pulled out from the fourth take-up roller (141) onto the superabsorbent polymer layer (13) to which the peat moss coating layer (14) is bonded, and a second heat bonding device (143) that applies heat to the edge of the superabsorbent polymer layer (13) and heat-bonds the dry cover layer (15) that has passed through the third press roller (142).

Accordingly, the above-described defecation pad (in which the anti-slip film layer (11), the first pulp layer (12), and the superabsorbent polymer layer (13) are laminated and bonded, and the peat moss coating layer (14) is adhered on the superabsorbent polymer layer (13)) enters a pair of third pressure rollers (142), and at the same time, the dry cover layer (15) pulled out from the fourth take-up roller (141) enters the pair of third pressure rollers (142) together, so that the dry cover layer (15) is pressed on the peat moss coating layer (14) of the defecation cover by the pair of third pressure rollers (142) and is directed toward the second heat bonding device (143).

Accordingly, by applying heat from the second heat bonding device (143) to the edge of the dry cover layer (15) and the superabsorbent polymer layer (13) of the excrement cover that have passed through the third pressure roller (142) and heat bonding, the dry cover layer (15) can be bonded to the superabsorbent polymer layer (13) while covering the peat moss coating layer (14), and since the dry cover layer (15) is made of a non-woven fabric, it instantly absorbs excrement, preventing excrement such as urine from getting on the pet's feet, and has the function of blocking the peat moss particles that make up the peat moss coating layer (14) from leaking to the outside.

Meanwhile, another embodiment of the secondary manufacturing device (140) of the diaper pad further bonds the second pulp layer (17) with an embossing structure between the peat moss coating layer (14) and the dry cover layer (15), as shown in FIG. 6, in addition to the fourth winding roller (141), the third pressure roller (142), and the second heat bonding device (143), a fifth winding roller (145) on which the second pulp layer (17) is wound, a fourth pressure roller (146) for pressing the second pulp layer (17) pulled out from the fifth winding roller (145) onto the superabsorbent polymer layer (13) to which the peat moss coating layer (14) is bonded before the dry cover layer (15) is laminated, and the second pulp layer (17) that has passed through the fourth pressure roller (146) is pressed against the dry cover layer (15). It may further include a third heat bonding device (147) that applies heat to the edge of the superabsorbent polymer layer (13) before lamination and performs heat bonding.

Accordingly, the above-described defecation pad (in which the anti-slip film layer (11), the first pulp layer (12), and the superabsorbent polymer layer (13) are laminated and bonded, and the peat moss coating layer (14) is adhered on the superabsorbent polymer layer (13)) enters the fourth pressure roller (146) and at the same time, the second pulp layer (17) pulled out from the fifth take-up roller (145) enters the pair of fourth pressure rollers (146) together, so that the second pulp layer (17) is pressed on the peat moss coating layer (14) of the defecation cover by the pair of fourth pressure rollers (146) and is directed toward the third heat bonding device (147).

Accordingly, by applying heat from the third heat bonding device (147) to the edge of the second pulp layer (17) and the superabsorbent polymer layer (13) of the defecation cover that have passed through the fourth pressure roller (146) and thermally bonding them, the second pulp layer (17) can be bonded onto the superabsorbent polymer layer (13) while covering the peat moss coating layer (14).

In this way, the second pulp layer (17) is laminated to cover the peat moss coating layer (14) and bonded to the edge of the superabsorbent polymer layer (13), and then the dry cover layer (15) can be laminated and bonded on top of the second pulp layer (17).

Accordingly, the second pulp layer (17) not only functions to buffer and distribute the load of a pet that has climbed onto the pee pad, but also double-blocks the external detachment of the peat moss particles forming the peat moss coating layer (14) together with the dry cover layer (15), thereby completely preventing and protecting the external detachment of the peat moss particles.

Meanwhile, an eco-friendly adhesive (16) is applied on the superabsorbent polymer layer (13), peat moss particles are sprayed on it, and then pressed. A pressing enhancer may be further applied on the eco-friendly adhesive (16) so that the peat moss particles are firmly pressed and fixed to the eco-friendly adhesive (16).

That is, a compression enhancer is applied on an eco-friendly adhesive (16), peat moss particles are sprayed on it, and then it can be compressed.

This compression improver can be formed by including 65 parts by weight of water, 8 parts by weight of 3-mercaptopropyltrimethoxysilane, 9 parts by weight of butylimidazole, 11 parts by weight of phosphate ester, 4 parts by weight of ammonium persulfate, and 3 parts by weight of sodium bicarbonate.

3-Mercaptopropyltrimethoxysilane is added to provide adhesion and bonding properties, butylimidazole is added to improve adhesion and accelerate curing, phosphate ester acts as a surfactant, ammonium persulfate acts as a catalyst, and sodium bicarbonate acts as a buffer.

The reason for limiting the composition and components and limiting the numerical value of the mixing ratio as described above is that the inventor analyzed the test results through repeated failures and found that the optimal effect was achieved at the limited composition and numerical ratio.

Additionally, a contamination-resistant coating layer made of a contamination-preventing coating composition may be applied to the sieve drum (131) to improve contamination resistance.

The above-mentioned anti-fouling coating composition contains sulfolaurate and cocamidopropyl betaine in a molar ratio of 1:0.01 to 1:2, and the total content of sulfolaurate and cocamidopropyl betaine is 1 to 10 wt% based on the total aqueous solution.

The molar ratio of the above sulfolaurate and cocamidopropyl betaine is preferably 1:0.01 to 1:2. If the molar ratio is outside the above range, there is a problem that the coating property of the sieve drum (131) is reduced or the moisture absorption on the surface increases after coating, resulting in the removal of the coating film.

The above sulfolaurate and cocamidopropyl betaine are preferably present in an amount of 1 to 10 wt% of the total aqueous composition. If the amount is less than 1 wt%, there is a problem that the applicability of the sieve drum (131) is reduced, and if the amount exceeds 10 wt%, crystal precipitation is likely to occur due to an increase in the thickness of the coating film.

Meanwhile, as a method of applying the composition for coating the inner contamination to the sieve drum (131), it is preferable to apply by spraying. In addition, the final coating film thickness of the sieve drum (131) is preferably 900 to 2300 Å. If the thickness of the coating film is less than 900 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and if it exceeds 2300 Å, there is a disadvantage of easy occurrence of crystal precipitation on the coating surface.

In addition, the composition for coating the present invention for anti-pollution coating can be prepared by adding 0.1 mol of sulfolaurate and 0.05 mol of cocamidopropyl betaine to 1000 ml of distilled water and then stirring.

The reason why the ratio of the above components and the thickness of the coating film are numerically limited as above is that the inventor analyzed the test results through repeated failures and found that the optimal anti-pollution coating effect was achieved at the above ratio.
