Description

{Pavement material of slip preventing with excellent abrasion resistance, and manufacturing method thereof}

The present invention relates to an anti-slip packaging material having excellent wear resistance and a method for manufacturing the same.

In general, anti-slip pavement is a facility installed to increase the skid resistance of the pavement to ensure safe driving of automobiles, etc., in areas where the skid resistance of the road surface is low, or where the road plane and longitudinal alignment are poor, to increase the skid resistance of the pavement surface and shorten the braking distance of automobiles, or to prevent traffic accidents by increasing the visibility of roads where people walk, such as school routes and crosswalks.

Such anti-slip pavements are installed in sections where the required level of skid resistance is not secured due to the road geometry and traffic characteristics, and their purpose is to increase friction. That is, when the skid resistance of the pavement falls below a certain level over the entire section as the road usage period increases, the road is repaired using an anti-slip paint composition to fundamentally increase skid resistance from the perspective of pavement maintenance. Recently, the demand for such anti-slip paint compositions is rapidly increasing as they are applied not only to roads but also to places where pedestrians are likely to slip, such as rooftops of buildings, outdoor parking lots, and parks.

However, in the case of existing anti-slip pavements, there is a problem in that the pavement surfaces are easily cracked or the adhesive strength weakens due to the load and impact of large trucks due to problems with the compatibility of resin and aggregate, and the anti-slip effect significantly decreases over time due to wear of the aggregate.

Meanwhile, as a similar prior literature on this, Korean Patent Publication No. 10-2006-0124544 is presented.

Republic of Korea Patent Publication No. 10-2006-0124544 (December 5, 2006)

In order to solve the above problems, the present invention aims to provide an anti-slip packaging material with excellent wear resistance and a method for manufacturing the same.

However, the above purpose is exemplary, and the technical idea of the present invention is not limited thereto.

One aspect of the present invention relates to an anti-slip packaging material including a basalt fiber surface-modified with a polyoxyethylene group-containing silane compound satisfying the following chemical formula 1 and a heat-insulating material surface-modified with a polyoxyethylene group-containing silane compound satisfying the following chemical formula 1.

[Chemical Formula 1]

(In the above chemical formula 1,

R ₁ to R ₆ are each independently an alkyl group having 1 to 3 carbon atoms or an alkoxy group having 1 to 3 carbon atoms, and must have at least one alkoxy group.

n is a real number between 5 and 100.)

More preferably, in the above aspect, n in the chemical formula 1 may be a real number of 10 to 50.

In the above aspect, the anti-slip packaging material may further include an acrylic base resin, and specifically, for example, the acrylic base resin may include polymethyl methacrylate (PMMA) resin, methyl methacrylate (MMA), and an acrylic monomer.

In the above aspect, the polymethyl methacrylate (PMMA) resin may have a weight average molecular weight of 30,000 to 60,000 g/mol and a glass transition temperature (Tg) of 50 to 70°C.

In the above aspect, the acrylic monomer may include at least one selected from alkyl (meth)acrylate; hydroxyalkyl (meth)acrylate; aminoalkyl (meth)acrylate; alkoxyalkyl (meth)acrylate; carboxyl group-containing acrylic monomer; epoxy-containing acrylic monomer; and glycol acrylic monomer, and more specifically, may include butyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, and isobornyl (meth)acrylate.

In the above aspect, the acrylic base resin may further include a urethane oligomer, and the urethane oligomer may have a weight average molecular weight of 5,000 to 20,000 g/mol and a viscosity of 30,000 to 40,000 cPs.

In the above aspect, the basalt fiber may be a chopped fiber having a length of 4 mm or less.

In the above aspect, the heat-insulating material may be at least one selected from zinc oxide (ZnO), titanium dioxide (TiO ₂ ), cerium oxide (CeO), tungsten oxide (WO ₃ ), antimony tin oxide (ATO), indium tin oxide (ITO), cesium tungsten oxide (CWO), and antimony trioxide-zinc oxide (Sb ₂ O ₃ -ZnO).

In addition, another aspect of the present invention relates to a method for producing an anti-slip packaging material, comprising: a) a step of producing a packaging material composition including an acrylic base resin, basalt fibers surface-modified with a polyoxyethylene group-containing silane compound satisfying the following chemical formula 1, and a heat-insulating material surface-modified with a polyoxyethylene group-containing silane compound satisfying the following chemical formula 1; and b) a step of applying the packaging material composition onto a base surface and then curing it.

[Chemical Formula 1]

(In the above chemical formula 1,

R ₁ to R ₆ are each independently an alkyl group having 1 to 3 carbon atoms or an alkoxy group having 1 to 3 carbon atoms, and must have at least one alkoxy group.

n is a real number between 5 and 100.)

The anti-slip packaging material according to the present invention can have significantly improved wear resistance and excellent durability by adding basalt fibers surface-modified with a polyoxyethylene group-containing silane compound to the packaging material composition, and thus has excellent long-term slip resistance and can prevent safety accidents even on wet roads. In addition, by surface-modifying the surface of basalt fibers with a polyoxyethylene group-containing silane compound and using them, the basalt fibers can be more uniformly dispersed, and thereby the packaging material can have uniform wear resistance and durability.

In addition, excellent heat-insulating performance can be secured by adding a heat-insulating material surface-modified with a polyoxyethylene group-containing silane compound to the packaging composition.

Hereinafter, a wear-resistant, anti-slip packaging material and a manufacturing method thereof according to the present invention will be described in detail. The drawings introduced below are provided as examples so that those skilled in the art can sufficiently convey the spirit of the present invention. Therefore, the present invention is not limited to the drawings presented below and may be embodied in other forms, and the drawings presented below may be illustrated in an exaggerated manner to clarify the spirit of the present invention. At this time, if there is no other definition in the technical and scientific terms used, they have the meaning commonly understood by those skilled in the art to which this invention belongs, and in the following description and the attached drawings, a description of well-known functions and configurations that may unnecessarily obscure the gist of the present invention will be omitted.

One aspect of the present invention relates to an anti-slip packaging material including a basalt fiber surface-modified with a polyoxyethylene group-containing silane compound satisfying the following chemical formula 1 and a heat-insulating material surface-modified with a polyoxyethylene group-containing silane compound satisfying the following chemical formula 1.

[Chemical Formula 1]

(In the above chemical formula 1,

R ₁ to R ₆ are each independently an alkyl group having 1 to 3 carbon atoms or an alkoxy group having 1 to 3 carbon atoms, and must have at least one alkoxy group.

n is a real number between 5 and 100.)

In this way, the anti-slip packaging material according to the present invention can have significantly improved wear resistance and excellent durability by adding the basalt fiber surface-modified with a polyoxyethylene group-containing silane compound to the packaging material composition, and thus can have excellent long-term slip resistance and prevent safety accidents even on wet roads. In addition, by surface-modifying the surface of the basalt fiber with a polyoxyethylene group-containing silane compound and using it, the basalt fiber can be more uniformly dispersed, and thereby the packaging material can have uniform wear resistance and durability.

In addition, excellent heat-insulating performance can be secured by adding a heat-insulating material surface-modified with a polyoxyethylene group-containing silane compound to the packaging composition.

Meanwhile, in one example of the present invention, the basalt fiber is manufactured by melting basalt at a high temperature of about 1500℃ and spinning it using centrifugal force, and has excellent wear resistance, tensile strength, heat resistance, elasticity, and other physical properties, thereby effectively improving the strength of the coating film, thereby achieving excellent wear resistance and durability. Preferably, the basalt fiber may be a chopped fiber having a length of 4 mm or less, and more preferably, a chopped fiber having a length of 0.1 to 2.5 mm. In this range, sufficient strength and wear resistance enhancement effects may be secured.

The above basalt fiber can be used by surface-modifying it with a polyoxyethylene group-containing silane compound in order to improve compatibility with a base resin. Specifically, for example, the polyoxyethylene group-containing silane compound can be one satisfying the following chemical formula 1.

[Chemical Formula 1]

In the chemical formula 1 above, R ₁ to R ₆ are each independently an alkyl group having 1 to 3 carbon atoms or an alkoxy group having 1 to 3 carbon atoms, and must have at least one alkoxy group, and n is a real number of 5 to 100. More preferably, in the chemical formula 1 above, R ₁ to R ₆ are each independently an alkoxy group having 1 to 3 carbon atoms, and n may be a real number of 10 to 50.

When using basalt fibers surface-modified with a polyoxyethylene group-containing silane compound satisfying this, the compatibility with the base resin is excellent, so that the basalt fibers are uniformly dispersed and mixed in the composition, thereby enabling the packaging material to have uniform wear resistance and durability.

The surface-modified basalt fibers may be added in an amount of 8 to 20 wt% of the total weight of the packaging composition, and more preferably, 12 to 16 wt%. The strength-enhancing effect is excellent in this range. On the other hand, when the surface-modified basalt fibers are added in an amount of less than 8 wt%, it is difficult to secure sufficient strength, and when they are added in an amount of more than 20 wt%, the additional strength-enhancing effect is minimal, while only the cost may increase, which is not good.

In one example of the present invention, the heat-insulating material is intended to provide heat-insulating performance to the packaging material, thereby suppressing the urban heat island phenomenon caused by the high surface temperature of the block surface due to the accumulation of solar infrared rays in the summer, and to reduce the heat of pedestrians. Any material commonly used in the art may be used without particular limitation, and specifically, for example, the material may be at least one selected from zinc oxide (ZnO), titanium dioxide (TiO ₂ ), cerium oxide (CeO), tungsten oxide (WO ₃ ), antimony tin oxide (ATO), indium tin oxide (ITO), cesium tungsten oxide (CWO), and antimony trioxide-zinc oxide (Sb ₂ O ₃ -ZnO).

At this time, the shape of the heat insulating material may be a particle shape such as a sphere, a rod shape, a needle shape, or a hollow shape, and the average particle diameter of the heat insulating material may be 0.01 to 5 ㎛, more preferably 0.1 to 3 ㎛, and even more preferably 0.5 to 1.5 ㎛. The heat insulating effect is particularly excellent in this range.

The above-mentioned heat-insulating material can be used by surface-modifying with a polyoxyethylene group-containing silane compound in order to improve compatibility with the base resin. Specifically, for example, the polyoxyethylene group-containing silane compound can be a polyoxyethylene group-containing silane compound satisfying the above-mentioned chemical formula 1, and the specific material can be the same as or different from the surface-modifying component of the basalt fiber.

The above surface-modified heat-insulating material can be added at 1 to 10 wt% of the total weight of the packaging composition, and more preferably, 3 to 6 wt%. The heat-insulating performance enhancement effect is excellent in this range. On the other hand, when the heat-insulating material is added at less than 1 wt%, it is difficult to provide heat-insulating performance, and when it is added at more than 10 wt%, the additional heat-insulating performance enhancement effect is minimal, while only the cost may increase, which is not good.

Meanwhile, an anti-slip packaging material according to an example of the present invention may further include an acrylic base resin. The acrylic base resin is intended to bind together each component constituting the composition and to ensure good adhesion to asphalt and concrete base surfaces, and may specifically include, for example, polymethyl methacrylate (PMMA) resin, methyl methacrylate (MMA), and an acrylic monomer.

In one example of the present invention, the PMMA resin may be manufactured by polymerizing MMA, and specifically, for example, the PMMA resin may have a weight average molecular weight of 30,000 to 60,000 g/mol, and more preferably, 40,000 to 50,000 g/mol. In addition, the PMMA resin may have a glass transition temperature (Tg) of 50 to 70°C. In this range, the PMMA resin has a hardness suitable for asphalt and concrete, and has excellent penetration power into the base surface, so that the adhesion may be further improved.

The above PMMA resin can be added in an amount of 5 to 15 wt% of the total weight of the packaging composition, and more preferably, 7 to 12 wt%. In this range, the PMMA resin can be well dissolved in the MMA and monomer mixture, and a working time of 10 to 30 minutes can be secured.

In one example of the present invention, the MMA enables the film to be stably formed when forming an anti-slip packaging material, and allows the PMMA resin to dissolve in the packaging material composition. The MMA may be added in an amount of 3 to 12 wt% based on the total weight of the packaging material composition, and more preferably, may be added in an amount of 5 to 10 wt%. When MMA is added in an amount of less than 3 wt%, the solubility is low, resulting in poor workability. When it exceeds 12 wt%, the tensile strength and elongation may be affected, which may lower the crack resistance of asphalt and concrete.

In one example of the present invention, the acrylic monomer is added to enable stable formation of a coating film when forming an anti-slip packaging material and to further improve adhesion to a base surface. For example, the acrylic monomer may include at least one selected from alkyl (meth)acrylate; hydroxyalkyl (meth)acrylate; aminoalkyl (meth)acrylate; alkoxyalkyl (meth)acrylate; carboxyl group-containing acrylic monomer; epoxy-containing acrylic monomer; and glycol-based acrylic monomer. More specifically, for example, alkyl (meth)acrylates such as methyl (meth)acrylate, ethyl (meth)acrylate, butyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, n-octyl (meth)acrylate, and isobornyl (meth)acrylate; Hydroxyalkyl (meth)acrylates, such as hydroxyethyl (meth)acrylate, hydroxypropyl (meth)acrylate, hydroxybutyl (meth)acrylate, and hydroxyhexyl (meth)acrylate; aminoalkyl (meth)acrylates, such as aminoethyl (meth)acrylate, N,N-dimethylaminoethyl (meth)acrylate, and t-butylaminoethyl (meth)acrylate; alkoxyalkyl (meth)acrylates, such as methoxyethyl (meth)acrylate and ethoxyethyl (meth)acrylate; carboxyl group-containing acrylic monomers, such as (meth)acrylic acid and carboxyethyl (meth)acrylate; epoxy-containing acrylic monomers, such as glycidyl (meth)acrylate; And it may include at least one selected from glycol acrylic monomers such as ethylene glycol (meth)acrylate, propylene glycol (meth)acrylate, methoxyethylene glycol (meth)acrylate, and methoxypropylene glycol (meth)acrylate;

As a more specific example, the acrylic monomer may include butyl (meth)acrylate, 2-ethylhexyl (meth)acrylate and isobornyl (meth)acrylate. Use of these in combination may be particularly desirable for improving adhesion to concrete and asphalt.

The above acrylic monomer may be added in an amount of 5 to 15 wt% of the total weight of the packaging composition, and more preferably, 8 to 12 wt%. When butyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, and isobornyl (meth)acrylate are used as the acrylic monomers, the acrylic monomers may contain 30 to 60 wt% of butyl (meth)acrylate, 20 to 50 wt% of 2-ethylhexyl (meth)acrylate, and 5 to 25 wt% of isobornyl (meth)acrylate, and more preferably, the acrylic monomers may contain 40 to 50 wt% of butyl (meth)acrylate, 30 to 40 wt% of 2-ethylhexyl (meth)acrylate, and 10 to 20 wt% of isobornyl (meth)acrylate.

In addition, the acrylic base resin may further include one or more selected from urethane oligomers and plasticizers.

In one example of the present invention, the urethane-based oligomer is added to improve the elongation of the coating film. Specifically, for example, the urethane-based oligomer may have a weight average molecular weight of 5,000 to 20,000 g/mol and a viscosity of 30,000 to 40,000 cPs. The elongation improvement effect is excellent in this range. On the other hand, when the viscosity is less than 30,000 cPs, the strength of the coating film may be reduced, and when it exceeds 40,000 cPs, workability may be poor.

The above urethane-based oligomer can be added in an amount of 1 to 10 wt% of the total weight of the packaging composition, and more preferably, 2 to 6 wt%. The elongation improvement effect is excellent in this range.

In one example of the present invention, the plasticizer is used to improve the flexibility of the base resin, and any plasticizer commonly used in the art may be used without particular limitation. As a specific example, one or more polyhydric alcohol compounds such as (C1-C10)alkanediol, (C1-C10)alkanetriol, or (C1-C10)glycol may be used.

The above plasticizer can be added in an amount of 0.1 to 5 wt% of the total weight of the packaging composition, and more preferably, 0.5 to 3 wt%. The flexibility-enhancing effect is excellent in this range.

In addition, the anti-slip packaging material according to one example of the present invention may further include surface-modified silica, and specifically, silica surface-modified with a polyoxyethylene group-containing silane compound may be used. In this case, since the polyoxyethylene group-containing silane compound is the same as described above, a duplicate description is omitted, and it may be the same as or different from the surface modifier used for surface modification of the basalt fiber.

In one example of the present invention, the silica is added to increase the frictional force of the coating film and improve the anti-slip performance, and it is preferable to use at least one selected from No. 4 yarn (16 to 20 mesh), No. 5 yarn (20 to 30 mesh), and No. 6 yarn (30 to 60 mesh).

The surface-modified silica may be added in an amount of 20 to 40 wt% of the total weight of the packaging composition, and more preferably, 25 to 35 wt%. In this range, the anti-slip performance is excellent. On the other hand, when the surface-modified silica is added in an amount of less than 20 wt%, it is difficult to secure sufficient frictional force, and when it is added in an amount of more than 40 wt%, the adhesive force to the base surface may be reduced, and the viscosity of the composition may become too high, resulting in poor workability.

In addition, the anti-slip packaging material according to one example of the present invention may further include a filler.

In one example of the present invention, the filler is added to improve anti-slip performance and control the viscosity of the paint, and may be specifically, for example, at least one selected from calcium carbonate, aragonite, and talc.

The above filler may be added in an amount of 10 to 35 wt% of the total weight of the packaging composition, and more preferably, 15 to 25 wt%. The anti-slip effect is excellent in this range. On the other hand, if the filler is added in an amount of less than 10 wt%, the content of other expensive raw materials may increase, which may increase the cost, and if it is added in an amount of more than 35 wt%, the content of other components such as base resin, basalt fiber, and heat-insulating material may decrease, making it difficult to secure sufficient adhesive strength, wear resistance, etc.

Meanwhile, the anti-slip packaging material according to one example of the present invention may further include an initiator. The initiator initiates a chain reaction of radical polymerization and crosslinks the reactive component of the acrylic base resin. Any initiator commonly used in the art may be used without particular limitation. Specifically, for example, a peroxide-based curing agent such as benzoyl peroxide (BPO) or dicumyl peroxide may be used.

The above initiator may be added in an amount of 0.1 to 5 wt% of the total weight of the packaging composition, and more preferably, 0.5 to 3 wt%.

In addition, the anti-slip packaging material according to an example of the present invention may further include functional additives depending on the purpose, and specifically, for example, may further include one or more of a thickener, a dispersant, a coloring pigment, a polymerization accelerator, an anti-foaming agent, a leveling agent, an ultraviolet stabilizer, and an adhesion promoter. The functional additives may be added in an amount of 0.1 to 5 wt% of the total weight of the packaging composition, but are not necessarily limited thereto.

For example, the thickener is for controlling the viscosity of the packaging composition, and any thickener commonly used in the art may be used without particular limitation, and a specific example thereof may be at least one selected from bentonite, carrageenate, ethyl cellulose, gelatin, maltitol, and sucrose.

The above dispersant is used to evenly disperse each component of the composition to maintain a constant quality. Any dispersant commonly used in the art may be used without particular limitation. As a specific example, at least one selected from polycarboxylic acid, naphthalene, melamine, and lignin may be used.

The above coloring pigment is intended to improve the distinctiveness and visibility of the road by adding color, and can be used without particular limitation as long as it is commonly used in the art, and as a specific example, it can be at least one selected from iron oxide, iron hydroxide, chromium oxide, barium lactate, barium carbonate, titanium oxide, titanium dioxide, manganese dioxide, titanium dioxide, zirconium silicate, carbon black, and sodium aluminosilicate, and the color selected accordingly can be a reddish brown pigment such as iron hydroxide, a yellow pigment such as iron hydroxide, a green pigment such as chromium oxide, a white pigment such as titanium oxide, and an ultramarine pigment such as sodium aluminosilicate, and the like, and pigments commonly commercially available in this field can be selected.

In addition, another aspect of the present invention relates to a method for manufacturing the above-described anti-slip packaging material, which may include the steps of: a) manufacturing a packaging composition including an acrylic base resin, basalt fibers surface-modified with a polyoxyethylene group-containing silane compound satisfying the following chemical formula 1, and a heat-insulating material surface-modified with a polyoxyethylene group-containing silane compound satisfying the following chemical formula 1; and b) applying the packaging composition onto a base surface and then curing it. At this time, since each component of the packaging composition is the same as described above, a duplicate description is omitted, and the method for manufacturing the composition and the anti-slip packaging material can be performed according to a conventional method.

[Chemical Formula 1]

R ₁ to R ₆ are each independently an alkyl group having 1 to 3 carbon atoms or an alkoxy group having 1 to 3 carbon atoms, and must have at least one alkoxy group.

[Property Evaluation]

The packaging compositions manufactured in Examples 1 to 13 and Comparative Examples 1 to 3 were applied and cured in accordance with KS M ISO 1513 to manufacture test pieces, and the physical properties were evaluated in accordance with the methods described below, and the results are shown in Table 1 below.

1) Wear resistance: The wear amount (mg) was measured based on 500,000 wear test cycles according to the KS M 6080 method.

2) Anti-slip performance: Anti-slip performance (BPN) was measured according to the KS F2375 method, and measurements were taken initially and after 500,000 wear tests.

3) Thermal insulation performance: The test specimen was placed vertically so that a 250 W infrared bulb was placed 24.5 cm away from the specimen surface, and the five sides except the bulb irradiation side were wrapped with 3 cm thick Styrofoam to insulate them. After that, infrared rays were irradiated for 0 and 240 minutes, and the temperature change (ΔT) of each test specimen was measured using a laser thermometer.

4) Adhesive strength: Adhesive strength (MPa) was measured according to the KS F 2386 method.

Referring to Table 1 above, in Examples 2 to 4, 7, 8, 11 and 12, in which 20 to 40 wt% of an acrylic base resin, 8 to 20 wt% of a surface-modified basalt fiber, 1 to 10 wt% of a surface-modified heat-insulating material, 20 to 40 wt% of a surface-modified silica and 10 to 35 wt% of calcium carbonate were added, the physical properties such as anti-slip performance, wear rate, heat-insulating performance and adhesive strength were excellent.

On the other hand, in the case of Example 1, where the content of the acrylic base resin was too low, the adhesive performance was not good, and problems such as cracks occurring in repeated wear resistance tests occurred. On the contrary, in the case of Example 5, where the content of the acrylic base resin was too high, the anti-slip performance and wear resistance were somewhat poor. In addition, in the case of Example 6, where the content of the surface-modified basalt fiber was too low, the wear resistance was poor, and in the case of Example 9, although the content of the basalt fiber was somewhat excessive, there was a problem that the cost increased significantly while the performance was similar to that of Example 8. In addition, in the case of Example 10, where the content of the surface-modified heat-insulating material was too low, the heat-insulating performance was not good, and conversely, in the case of Example 13, where the content of the heat-insulating material was too high, the content of calcium carbonate was relatively reduced, which had the disadvantage of somewhat lowering the anti-slip performance.

Meanwhile, in the case of Comparative Example 1, which added non-surface-modified basalt fibers and silica, the physical properties were significantly reduced, and in the case of Manufacturing Example 3, which was manufactured using a different type of silane compound as a surface modifier instead of a polyoxyethylene group-containing silane compound, and Comparative Example 2, which added surface-modified basalt fibers and Manufacturing Example 4, the physical properties were somewhat reduced compared to Example 3. In addition, in the case of Comparative Example 3, which added only calcium carbonate instead of basalt fibers, the anti-slip performance was significantly reduced after the abrasion resistance test, and the adhesive strength was also poor.

Although the present invention has been described through specific matters and limited examples as above, these have been provided only to help a more general understanding of the present invention, and the present invention is not limited to the above examples, and those skilled in the art to which the present invention pertains can make various modifications and variations from this description.

Therefore, the idea of the present invention should not be limited to the described embodiments, and all things that are equivalent or equivalent to the claims described below as well as the same are included in the scope of the idea of the present invention.
