Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a non-slip packaging material for fast curing type iron having high durability and a method of manufacturing the same. BACKGROUND ART < RTI ID = 0.0 >

The present invention relates to a fast-curing slip resistant packaging material composition having a high durability and a method of manufacturing the same. More specifically, the present invention relates to a binder resin comprising a mixture of polymethyl methacrylate and methyl methacrylate with a urethane oligomer for improving the elongation, Is excellent in durability such as elongation, impact resistance, abrasion resistance and adhesion property by mixing the aggregate and the filler which are given as main constituents and the pigment in a proper ratio and is not greatly dependent on the external condition because the curing speed is high at room temperature or low temperature Hardening type non-slip packaging material composition having a high durability and capable of greatly improving work efficiency by a construction method of a coating type.

As a coating composition for anti-slip, which is applied to a conventional heavy paint or steel structure, most of the non-slip packaging materials are formed by spraying or mixing an aggregate using a thermosetting epoxy resin or a solvent type urethane. This type of packaging method is called a knitting method by chipping (a method of spraying an aggregate). Most of epoxy type synthetic resin is used in the heavy type paint. However, the epoxy type resin has a problem of root hardening, There is a problem that it takes a lot of time to open the vehicle after construction due to the hardening property which does not occur.

In order to solve the construction problems using such a synthetic resin, the acrylate resin was applied to the non-slip packaging material to shorten the curing time at low temperatures. However, the resin having a high cross-link density has problems such as cracks and film loss Respectively. Particularly, the use of a reactive resin having a high strength or a high hardness causes cracks and dropouts, resulting in serious damage such as fracture of a non-slip packaging material, particularly in steel structures. Often, there are a series of problems that arise in the deck of a ship's hull and ship.

In order to overcome these problems, especially efforts have been made to improve the elongation, and further development of techniques such as dispersing or blending of the rubber has been carried out. However, a product with excellent elongation has problems such as lifting or tearing due to external impact And a product in which rubber-based resin or rubber powder is dispersed has problems such as adhesion with resin and compatibility. Particularly, in a product in which rubber is dispersed, there is a problem that the abrasion performance remarkably drops due to adhesion problems between rubber and resin. The slip resistant packaging material applied in this way resulted in defects such as peeling and peeling off after being applied to ships, laminates or steel.

Korean Patent No. 10-1442536 discloses a non-slip packaging composition using an acrylic mixture as a reactive resin. However, it is suitable for an anti-slip packaging material for asphalt concrete roads. However, when applied to a non-slip or anti- Coating film loss, and the like.

Therefore, in order to solve such problems, it is possible to accelerate the curing at room temperature without special equipment for drying or drying for a long period of time in the case of the anti-slip packaging material of a heavy or steel structure, and a new slip resistant with improved durability such as elongation, abrasion resistance, R & D on packaging materials is urgently required.

FIG. 2 is a graph showing the adhesion test results of the anti-slip packaging materials prepared in Examples 1 to 3 and Comparative Examples 1 and 2 of the present invention.

Hereinafter, the present invention will be described in more detail with reference to one embodiment.

The present invention relates to a curable resin composition comprising a main portion and a curing agent portion, and the main portion thereof comprises polymethyl methacrylate, methyl methacrylate, urethane oligomer, aggregate, filler, pigment and additives, wherein the curing agent is selected from benzoyl peroxide, dicyclohexyl phthalate, Silicon dioxide and a compounding water.

Specifically, the present invention provides a non-slip packaging composition comprising a base portion and a curing agent portion, wherein the base portion comprises 4 to 7% by weight of polymethylmethacrylate, 15 to 22% by weight of methylmethacrylate, Wherein the curing agent part contains 9 to 12 wt% of a urethane oligomer, 20 to 30 wt% of an aggregate, 20 to 25 wt% of a filler, 4 to 7 wt% of a pigment and 9 to 16 wt% of an additive, Wherein the composition comprises 40 to 55% by weight of benzoyl, 40 to 55% by weight of dicyclohexyl phthalate, 2 to 3% by weight of silicon dioxide, and 2 to 3% by weight of a compounding agent.

Particularly, the main part of the fast-curing slip resistant packaging material composition is a binder resin having main functions such as coating film formation, quick curability at low temperature, and adhesiveness, and the like. The binder resin includes polymethylmethacrylate (PMMA), methylmethacrylate (MMA) An aggregate material and a filler material which impart sliding resistance and abrasion resistance, and a pigment which imparts coloring of the packaging material.

The rapid-curing non-slip packaging composition of the present invention is a packaging composition in a form to be applied differently from a conventional anti-slip packaging material for chipping used in a conventional heavy-duty vessel and a ship. All the materials used in the present invention are a mixed- It is possible to exhibit uniform physical properties without separation of materials or additional mixing of auxiliary materials.

According to a preferred embodiment of the present invention, the polymethylmethacrylate (PMMA), the methyl methacrylate (MMA) and the urethane oligomer corresponding to the binder resin in the anti-slip package composition as described above have a problem in adhesiveness with the material And its usage is limited within a certain range. Particularly, the acrylic monomer has high solubility and dissolves the applied material (steel structure or the like), which causes a problem of breakage of the undercoating or coating surface. It is advisable to quantitatively add the desired amount depending on the solubility of the material used. In the present invention, it is preferable to increase the amount of methyl methacrylate, which has relatively low solubility in the acrylic monomer, in order to minimize damage such as old film and rust-preventive film due to dissolution. Preferably, the amount of methyl methacrylate used is 15 to 22% by weight based on 100% by weight of the main portion.

According to a preferred embodiment of the present invention, the polymethylmethacrylate in the binder resin may have a number average molecular weight (Mn) of 110,000, a specific gravity of 1.18, and a glass transition temperature of 114 占 폚 in the form of beads. The methyl methacrylate may have a number average molecular weight (Mn) of 86 and a viscosity (25 ° C) of 1 to 10 mPa.s. When the methyl methacrylate is used in an amount of less than 15% by weight based on 100% by weight of the main portion, the dilution ratio with respect to the work performance and the material may be low, and the viscosity and dispersion of the product may be problematic. It is preferable to limit the amount of use thereof because another problem may arise by melting the existing coating film and surface.

According to a preferred embodiment of the present invention, it is important that the urethane oligomer is an alipahatic oligomer having two or more functional groups synthesized with non-discolored isocyanate, which is used for improving elongation of an existing packaging material composition. Specifically, the urethane oligomer may have a number average molecular weight (Mn) of 8,000 to 19,000 and a viscosity of 30,000 to 40,000 mPa · s. In particular, when the oligomer having a viscosity of less than 30,000 mPa · s is used, And when the oligomer is used in excess of 40,000 mPa · s, the work performance of the non-slip packaging material is significantly lowered.

The urethane oligomer may be used in an amount of 9 to 12% by weight based on 100% by weight of the main component. When the amount of the urethane oligomer is less than 9% by weight, the hardness of the packaging material is increased, and a desired level of bending performance, If it is more than 12% by weight, the elongation is increased but the tensile strength and the adhesive strength are lowered, and the packaging material is broken. In particular, the urethane oligomer has a high viscosity, and as the amount of the urethane oligomer is increased, the workability of the non-slip packaging material is lowered. Therefore, it is preferable to use the urethane oligomer within an appropriate range of 9 to 12% by weight in consideration of the physical properties and work performance of the slip- The urethane oligomer may be at least one selected from the group consisting of isophorone diisocyanate (IPDI) and hexa-methylene diisocynate (HMDI).

According to a preferred embodiment of the present invention, the aggregate is used for improving the sliding resistance, abrasion resistance and coating ability of the packaging material, and 20 to 30% by weight can be used for 100% by weight of the main portion. Specifically, when the amount is less than 20% by weight, the sliding resistance is decreased. When the amount is more than 30% by weight, the wettability with the material is insufficient and the workability is poor. The aggregate may be at least one selected from the group consisting of silicon dioxide, silica, silica ceramic powder, aluminum oxide (Al ₂ O ₃ ), cement, steel making slag, shell powder and glass beads. Preferably, the aggregate may be a quartz aggregate composed of silicon dioxide. The size of the aggregate may range from 2 to 4 ranges. The aggregate may have an average particle size of 0.1 to 5 mm. Specifically, when the average particle size is less than 0.1 mm, there is a problem that the sliding resistance is deteriorated. When the average particle size is more than 5 mm, the wettability with the material is insufficient.

According to a preferred embodiment of the present invention, the filler is used for improving abrasion resistance and strength of a product, and is used in an amount of 20 to 25% by weight based on 100% by weight of the main portion. When the content is less than 20% The performance and the abrasion performance are deteriorated and the strength of the product is greatly lowered. When the amount exceeds 25 wt%, the viscosity of the oil is increased due to the oil absorption, and the coating performance is poor.

The filler may be at least one selected from the group consisting of calcium bicarbonate, talc, calcium carbonate, barium sulfate, and magnesium hydroxide. It is preferable to use calcium bicarbonate. In addition, the filler may have a particle size of 200 to 400 mesh. If the particle size is less than 200 mesh, there is a problem that rigidity such as impact resistance is lowered. If the particle size is more than 400 mesh, there is a problem that sliding resistance is lowered.

According to a preferred embodiment of the present invention, the pigment may be a reddish brown or black colored pigment having a very good concealability with respect to the material and visibility, and iron oxide may be preferably used. In addition, the amount of use is not adversely affected by the addition of 4 to 7% by weight based on 100% by weight of the main portion.

According to a preferred embodiment of the present invention, the additive comprises 2 to 3% by weight of paraffin wax, 3 to 5% by weight of a coupling agent, 1 to 3% by weight of an ultraviolet stabilizer, 1 to 2% by weight of a dispersant, And 2 to 3% by weight of fumaric acid.

Specifically, the paraffin wax is used for blocking oxygen at the time of forming a coating film. The paraffin wax is used in an amount of 2 to 3% by weight, and when the content is out of the above range, the physical properties of the product deteriorate.

The coupling agent has an effect of enhancing the adhesion between the organic and inorganic materials. In particular, the adhesive performance of the slip resistant packaging material is increased, and the adhesive agent is also excellent in adhesion to tiles and marble. The coupling agent is preferably used in an amount of 3 to 5% by weight, and acryloylpropyltrimethoxysilane having an acryl functional group and a number average molecular weight (Mn) of 234 is preferably used.

1 to 3% by weight of TINUVIN 326 manufactured by BASF is used as the ultraviolet stabilizer, and resistance to ultraviolet rays is strongly exhibited when the amount of the ultraviolet stabilizer is increased. However, productivity is lowered due to an increase in cost when used in excess of 3% by weight.

The dispersant is used in an amount of 1 to 2% by weight based on 1 to 2% by weight of a phosphoric acid ester salt of a high molecular weight copolymer having a pigment-affinity group of BYK, which is soluble in pigmenting and dispersing pigment iron oxide. When the amount is less than 1% And when the amount exceeds 2% by weight, the overall property deterioration occurs.

The fumed silica is used in an amount of 2 to 3% by weight to give effects such as thickening, workability enhancement and sedimentation prevention of the product. When the amount of the fumed silica is less than 2% by weight, the effect of preventing thickening and sedimentation of the product is obtained When it is used in an amount exceeding 3% by weight, the wettability with the material is deteriorated and the workability is lowered.

According to a preferred embodiment of the present invention, 1 to 5 parts by weight of the curing agent may be mixed with 100 parts by weight of the main portion. Specifically, if the amount of the curing agent is less than 1 part by weight, the curing time tends to be long. If the amount is more than 5 parts by weight, the physical properties of the cured product may deteriorate. Preferably, the curing agent is mixed with 1 to 3 parts by weight, more preferably 3 parts by weight.

The present invention also provides a method for preparing a fast-curing slip resistant packaging material composition, which comprises preparing 4-7% by weight of polymethylmethacrylate, 15-22% by weight of methylmethacrylate, 9-12% by weight of urethane oligomer, From 20 to 25% by weight of filler, from 4 to 7% by weight of pigment and from 9 to 16% by weight of additive; 40 to 55% by weight of benzoyl peroxide, 40 to 55% by weight of dicyclohexyl phthalate, 2 to 3% by weight of silicon dioxide and 2 to 3% by weight of compounding water; And 1 to 5 parts by weight of a curing agent for 100 parts by weight of the main portion.

The present invention also provides a method of constructing a high-durability anti-slip package comprising the step of applying the anti-slip packaging composition to the surface of a steel structure to form a non-slip layer.

Therefore, the fast-curing type non-slip packaging composition according to the present invention has a high curing rate at a room temperature or a low temperature after construction, so that the vehicle can pass and walk within one to two hours after the construction, and the economic loss can be reduced by shortening the construction period. Especially during the winter season, it can be cured at low temperature without any special equipment such as heating at a subzero temperature, which is advantageous in that it is not much dependent on external conditions.

In order to improve the elongation to polymethyl methacrylate and methyl methacrylate, binder resin in which urethane oligomer is mixed, aggregate for imparting sliding resistance and filler are mixed with pigments to prepare fast-curing slip resistant packaging composition, Durability such as impact resistance, abrasion resistance and adhesiveness is excellent, and the service life of the non-slip wrapping material can be increased.

In addition, unlike the conventional chipping-type non-slip wrapping material which is used in a conventional heavy-duty type or ship using a hardening agent at room temperature in a field stirring type, work efficiency can be greatly improved by applying using a special roller or spray.
