Problems solved by technology

This creates a contradiction. On the one hand, the paint film requires high wear resistance, and on the other hand, it needs to be easily polished during UV paint construction. This contradiction has not been effectively resolved so far.

Abstract

The invention discloses a wear-resistant UV (ultraviolet) photocuring woodware paint composition which comprises base resin, reactive diluent, photoinitiator and wear-resistant micro powder, wherein the wear-resistant micro powder is one or a combination of both of silicon oxide powder and aluminum oxide powder, the powder composing the wear-resistant micro powder has at least two particle sizes, the difference between the at least two particle sizes is at least 100 meshes, and the mass percent of the wear-resistant micro powder in the composition is 6-13%; and the composition further comprises talcum powder, the talcum powder also has at least two particle sizes, the difference between the two particle sizes is at least 100 meshes, the mass percent of the talcum powder in the composition is 8-18%, the particle size of the talcum powder is smaller than that of the wear-resistant micro powder, and the difference between the particle sizes of the talcum powder and the wear-resistant micro powder is at least 300 meshes. The paint composition disclosed by the invention ensures sanding performance in application, and also ensures wear resistance of a paint film.

Description

technical field [0001] The invention relates to a coating composition, in particular to a UV light curing wood coating composition. Background technique [0002] In 1946, Inmout Company of the United States obtained the first patent of UP / styrene UV curing ink. In the early 1950s, a large number of theoretical research articles were published. In the early 1960s, it entered commercial application (Germany first produced unsaturated polyester-based wood filler, the UV lamp power density was 30w / cm, and the line speed was 10 m / min (more than 3 lamps irradiated at the same time). At present The line speed of UV curing in the printing industry reaches 50-400 m / min. In the early 1970s, the acrylate curing system entered industrial application, the UV lamp power was increased to 80w / cm and effective reflectors were used to overcome the limitation of oxygen inhibition. Problem; In the 1980s, it was only developed and applied in developed countries and regions (in 1986, the United...
