Problems solved by technology

However, due to the smooth and uniform surface of the coating applied by roller coating, and the characteristics of high crosslinking, solvent-free, and instant curing of UV coatings, the UV coating applied by roller coating cannot produce special texture, anti-skid performance, and scratch resistance. Excellent surface effect
[0003] As consumers have higher and higher requirements for the scratch resistance and durability of the coating surface, in recent years, EN 16094 (method for the determination of micro-scratch resistance of laminated floor coverings) has been introduced into the flooring industry at home and abroad. Within the quality requirements, this standard is to use special scouring pads as abrasives on the surface of the floor, and use the Lisaru curve movement to test the scratch resistance of the floor under a specific load. The test results are graded as B1, B2, B3, and B4. , B5 level means that B1 level is the best result, indicating that the floor surface has no scratches at all. At present, coatings containing wear-resistant particles are used to improve this performance, but there is no mature solution for stable mass production. The quality reaches B1 class products

Abstract

The invention relates to the field of coatings, in particular to a UV coating with a special convex point structure and a preparation method of the UV coating. According to the first aspect, the UV coating is provided, the surface of the UV coating is provided with convex point structures which are distributed at equal intervals or irregularly, the diameter of each convex point is 0.05-2 mm, and the distance between every two adjacent convex points is 0.05-3 mm. The preparation method of the coating is simple, and batch stable production can be realized; the coating is good in anti-skid effect, the problems of surface scratching and dusting of the coating containing wear-resistant particles in the processes of transportation, wax sealing, packaging, paving and the like are solved, the micro-scratching performance reaches B1 level, and the coating has breakthrough significance in the floor industry; meanwhile, the surface gloss of the coating is soft and uniform, the fluctuation range is smaller, and high-grade, comfortable and soft visual perception can be generated.

Description

technical field [0001] The invention relates to the coating field, more specifically, the invention relates to a UV coating with a special bump structure and a preparation method thereof. Background technique [0002] UV coatings have attracted widespread attention because of their environmental protection, solvent-free, fast curing, high-efficiency production, and superior performance. In recent years, due to increasingly stringent environmental protection requirements, UV coatings have become more and more widely used. Roller coating is the most commonly used construction method for UV coatings. It has the characteristics of high production efficiency, automation, less labor, and environmental protection. Especially in the flooring industry, more than 90% of the coatings are applied by roller coating. However, due to the smooth and uniform surface of the coating applied by roller coating, and the characteristics of high crosslinking, solvent-free, and instant curing of UV ...
