Problems solved by technology

However, in the case of general UV paint spraying such a large topcoat, the scratch resistance performance often cannot meet the market requirements. The traditional method is to use UV primer and then spray PU topcoat
This results in more processes, longer working hours, and the use of PU paint, which releases a large amount of organic solvents to pollute the atmosphere. The overall efficiency and benefits are not high, which reduces the overall efficiency of coating.

Abstract

The invention relates to the field of paints and particularly relates to an anti-scratching ultraviolet curing paint. The anti-scratching ultraviolet curing paint comprises the following components in percentage by weight: 20-45 percent of resin, 15-35 percent of a monomer, 1-5 percent of a photo-initiator, 1-5 percent of other aids and 20-50 percent of a solvent. The ultraviolet curing paint disclosed by the invention is automatically sprayed on a base material by using equipment, so the production efficiency can be greatly improved. After curing, the ultraviolet curing paint can obtain extremely good levelling property, can have a surface effect of a PU paint and is better than the PU paint in hardness and scratching resistance.

Description

[0001] technical field [0002] The invention relates to the field of coatings, in particular to a scratch-resistant ultraviolet curing paint. [0003] Background technique [0004] UV paint is a light-curing paint. It is currently a widely used furniture paint. Its main features are: after strong ultraviolet light curing treatment, the color is stable and always new. Therefore, it is widely used in office furniture and other aspects, and has been used in large-area office furniture in recent years. However, in the case of general UV paint spraying such a large topcoat, the scratch resistance performance often fails to meet market requirements. The traditional method is to use UV primer and then spray PU topcoat. This results in more processes, longer working hours, and the use of PU paint, which releases a large amount of organic solvents to pollute the atmosphere. The overall efficiency and benefits are not high, which reduces the overall efficiency of painting. ...
