Description

Technical Field

[0001] The present application relates to the technical field of varnish, and in particular to an anti-skid and wear-resistant varnish and a preparation method and application thereof. Background Art

[0002] As consumers' requirements for product quality and appearance continue to increase, the surface treatment technology of packaging materials has also developed rapidly. In the fields of business publishing, food packaging, pharmaceutical packaging, etc., more and more glazing processes are used to protect packaging and increase the appearance. Especially for fast-moving consumer goods such as food packaging, the green environmental protection and low cost of water-based varnish are more conducive to the use of glazing technology. However, due to changes in production methods or improved production efficiency, such as the use of ramps to transport packaged products, the packaging is required to have better anti-slip properties. The circulation and transportation of goods across the country require the packaging to have better wear resistance and water resistance. The current varnish products generally cannot meet the requirements of both wear resistance and slippage, and their application is subject to certain restrictions. At present, the commonly used methods in the industry mainly include: adding diatomaceous earth and other particulate matter to enhance the anti-slip performance. This method can significantly increase the friction coefficient, but it is easy to cause the surface to be rough and uneven, affecting the appearance; by adding nano-silicon dioxide and other hard particles to improve wear resistance, this type of method can effectively improve the surface hardness, but in actual production, it often causes the coating uniformity to decrease due to poor dispersion; using ultraviolet light curing technology to quickly form a tough protective layer. This technology is highly efficient and suitable for large-scale continuous production, but due to the high cost and the existence of small molecule migration, it limits its wide application in food, medicine and other fields. Although the above methods have their own advantages, they are also accompanied by different problems.

[0003] In summary, although the existing packaging material surface treatment technology can achieve good results in some aspects, it generally has the problem of insufficient comprehensive performance, such as the inability to balance anti-slip and wear resistance, poor aesthetics, high cost, etc., and cannot fully meet the needs of the modern packaging industry. Summary of the invention

[0004] In order to solve the above technical problems, the present application provides an anti-skid and wear-resistant varnish and a preparation method and application thereof.

[0005] In a first aspect, the present application provides an anti-skid and wear-resistant varnish, specifically comprising the following components in parts by weight: 60-70 parts of a composite emulsion, 25-35 parts of a water-soluble acrylic resin, 10-20 parts of a composite copolymer rubber powder, 0.5-1.2 parts of a wetting and leveling agent, 0.04-0.08 parts of a defoaming agent, 8-12 parts of ammonia water, and 15-22 parts of water; The composite emulsion is composed of polyacrylic acid film-forming emulsion, wax emulsion CT1806, wax emulsion UltralubeGA 6668, and styrene acrylic emulsion are mixed in a weight ratio of 100:6-15:5-10:60-90; The composite copolymer rubber powder is prepared by mixing polylactic acid glycolic acid copolymer and ethylene / vinyl acetate copolymer rubber powder in a weight ratio of 10:0.5-3.

[0006] In the technical solution provided by the present application, polyacrylic acid film-forming emulsion is used as a film-forming substance, and polyacrylic acid emulsion has excellent film-forming properties. It can form a tough, transparent film after drying, providing good wear resistance and protection effect for varnish. Wax emulsion The combination of CT1806 and wax emulsion Ultralube GA 6668 further enhances the anti-skid and wear resistance of the varnish. The wax particles in these two wax emulsions can migrate to the surface of the film during the film-forming process, forming a layer of microscopic concave-convex structure. This structure not only increases the roughness of the film surface and provides a better anti-skid effect, but also reduces the direct contact between the object and the film surface, thereby reducing wear. Adding a small amount of styrene acrylic emulsion to the composite emulsion can react with polyacrylic acid film-forming emulsion and wax emulsion. CT1806 and wax emulsion Ultralube GA 6668 are well compatible and form a uniform film during the drying process; this film not only has excellent adhesion to the substrate, but also can further improve the overall performance of the varnish.

[0007] In addition, the present application selects polylactic acid-hydroxyacetic acid copolymer and ethylene / vinyl acetate copolymer powder in a specific weight ratio to form a composite copolymer powder, which each plays a unique role in the preparation of anti-skid and wear-resistant varnish, and together provide the varnish with excellent anti-skid and wear-resistant properties.

[0008] As a polymer material with good biocompatibility, the introduction of polylactic acid-co-glycolic acid copolymer can enhance the flexibility and durability of varnish. When combined with other ingredients, it can form a tough protective film, effectively resisting external friction and wear, and improving the wear resistance of the surface of the object. Ethylene / vinyl acetate copolymer powder has good adhesion and flexibility, which can increase the adhesion between the varnish and the substrate, ensuring that the varnish is firmly attached to the surface of the object; at the same time, its flexibility also enables the varnish to better adapt to the slight changes on the surface of the object and reduce the cracks or peeling caused by external forces. More importantly, the combination of polylactic acid-co-glycolic acid copolymer and ethylene / vinyl acetate copolymer powder can produce a synergistic effect and further improve the anti-slip performance of the varnish. By adjusting the formula and process conditions, a microscopic concave-convex structure can be formed on the surface of the varnish to increase the surface roughness. This structure not only provides a better anti-slip effect, but also reduces the wear rate.

[0009] Preferably, the anti-skid and wear-resistant varnish specifically comprises the following components in parts by weight: 62-68 parts of composite emulsion, 27-32 parts of water-soluble acrylic resin, 12-18 parts of composite copolymer rubber powder, 0.8-1.0 parts of wetting and leveling agent, 0.05-0.07 parts of defoaming agent, 9-11 parts of ammonia water, and 18-20 parts of water.

[0011] After experimental analysis, it can be known that the present invention uses the polyacrylic acid film-forming emulsion and wax emulsion in the above weight ratio. The performance of the varnish prepared by mixing CT1806, wax emulsion Ultralube GA 6668 and styrene acrylic emulsion to form a composite emulsion is further improved.
