Problems solved by technology

[0004] 1. The actual application results of the product cannot reach the effect claimed in the data
[0005] 2. Often only focus on the realization of one performance or two performances, and there are no reports of similar products that take into account the three performances at the same time
[0006] 3. The overall cost of production is high
[0007] 4. There are many painting processes. According to the relevant product information, some of them need to go through 17 paint coating processes in order to achieve wear-resistant and scratch-resistant functions, and some even have as many as 20 processes.

Abstract

The invention belongs to the field of ultraviolet curable new materials and particularly relates to a protective and decorative coating system for solid wood boards such as solid wood floorings, multilayer solid wood boards, bamboo floorings, reinforced composite floorings, furniture and the like. The invention provides a high-wear-resistance antiscratch and antifouling solid wood board ultraviolet curable coating system, which is abbreviated as 3N UV coating system coating. The high-wear-resistance antiscratch and antifouling solid wood board ultraviolet curable coating system consists of UVundercoat, UV wear-resistance topcoat and UV antifouling topcoat. Soft and hard or hard and soft alternating coating is performed according to the hardness and flexibility of films formed by the UV undercoat, the UV wear-resistance topcoat and the UV antifouling topcoat are coated, under the action of a photoinitiator, the UV wear-resistance topcoat and the UV antifouling topcoat are cured by ultraviolet to form films respectively, and thus, soft and hard alternating multilayer coating film structures with different flexibilities and high interlayer adhesive force are formed and the characteristics of high wear resistance, high scratch resistance and high fouling resistance are realized.

Description

technical field [0001] The invention belongs to the field of ultraviolet curing new materials. In particular, it relates to the protection and decoration coating system for solid wood panels such as solid wood flooring, multi-layer solid wood flooring, bamboo wood flooring, laminate flooring, and furniture. technical background [0002] Ultraviolet radiation curing technology is a new green technology, and the ultraviolet curing coatings produced by this technology are referred to as UV coatings. At present, my country's floor and furniture industries are increasingly using UV curing technology for protective and decorative coating of panels. With the improvement of people's living standards, consumers have higher and higher requirements for floor and furniture coating, especially emphasizing the high scratch resistance, high stain resistance and high wear resistance of the coating film. [0003] Many UV coating companies have developed related products. Based on the curre...
