Process for coating aluminium oxide at surface of plastic floor tile

Abstract

A process for coating alumina on the surface of plastic floor tile includes such steps as goating UV-sensitive resin, spraying alumina sand, using UV lamp to rdiate it for hardening unit, coating UV-sensitive resin again, and using UV lamp to radiate it again. Its advantages are high resistance to abrasion, scraping, corrosion and compression, and stereoscopic grains.

Description

technical field [0001] The present invention relates to a method for coating alumina on the surface of plastic floor tiles, more specifically, a method for coating alumina sand by spraying, coating alumina in two layers of photosensitive UV resin coatings, The process of coating aluminum oxide on the surface of plastic floor tiles by two coatings of photosensitive UV resin can prevent aluminum oxide from settling on the surface of the finished wear-resistant plastic floor tiles, prevent alumina sand from falling off, and make the surface of plastic floor tiles form excellent adhesion. , wear resistance, scratch resistance, corrosion resistance, compression resistance and three-dimensional texture. Background technique [0002] Although the traditional plastic floor tiles are easy to construct, their sandy matte effect, wear resistance, scratch resistance, skid resistance, corrosion resistance and pressure resistance are not as good as traditional ceramic and stone floor tile...

AI Technical Summary

Problems solved by technology

[0007] 1. In the photosensitive UV resin, adding alumina in the way of internal addition is easy to cause alumina to settle in the photosensitive UV resin due to the relatively heavy specific gravity of alumina;

[0008] 2. In the above method, the aluminum oxide photosensitive UV resin is coated by rollers, so that the surface of the finished plastic floor tile cannot form a matte effect similar to the sandy texture of the surface of ceramic stone and ground building materials;

[0009] 3. The alumina photosensitive UV resin on the surface of the finished plastic floor tiles, because the alumina has settled, the surface of the finished plastic floor tiles cannot form the effects of wear resistance, scratch resistance and anti-slip properties;

[0010] 4. In the above method, after the addition of alumina is increased, the finished plastic floor tiles will produce wear-resistant, scratch-resistant and matte effects similar to the surface of ceramic stone and ground building materials, but the viscosity of alumina photosensitive UV resin will decrease. Increase, and the thickness of the alumina photosensitive UV resin coated on the surface of the semi-finished product will also increase, and the cost of manufacturing plastic floor tiles will also increase;

[0011] 5. In the above method, silicon dioxide (SiO 2 ) photosensitive UV resin, so that the added silicon dioxide (SiO 2 ) particles cannot evenly protrude from the photosensitive UV resin, and silicon dioxide (SiO 2 ) Poor wear resistance and scratch resistance, easy to fall off, resulting in an extremely unsatisfactory sandy matte effect on the surface of the finished plastic floor tiles, that is, extremely poor wear resistance, scratch resistance, and slip resistance

[0012] The inventor of the present invention has been engaged in the development and research of plastic floor tiles for many years, and has a considerable degree of familiarity with and understanding of the advantages and disadvantages of the structure of plastic floor tiles. In view of the aforementioned traditional plastic floor tile manufacturing process, aluminum oxide is added to the photosensitive UV by internal addition. In the resin, it will cause alumina to settle, and the addition of silicon dioxide (SiO 2 ) added to the photosensitive UV resin can not produce better roughness and other shortcomings. The inventor of this case aimed at the above shortcomings and conducted research and improvement, hoping to create a more practical plastic floor tile. The inventor, in the spirit of excellence, Continuous research and thinking finally complete the present invention
