Problems solved by technology

However, in terms of spraying matte topcoats, traditional UV is better than curing speed too fast, or adding solvents to achieve construction viscosity, resulting in surface effects that are not as good as traditional PU paints and increased VOC emissions. The performance of traditional water-based paints cannot reach the current use. PU type products
Using PU paint, a large amount of organic solvents released pollutes the atmosphere, and the overall efficiency and benefit are not high, which reduces the overall efficiency of painting

Abstract

The invention discloses waterborne UV-curable matt paint for furniture. Raw materials of the paint are composed of the following ingredients (by weight): 30-50% of a polyurethane acrylate emulsion, 20-40% of a self-drying acrylate emulsion, 5-10% of purified water, 5-10% of water-based color paste, 1-5% of white carbon black fumed silica, 3-5% of a photoinitiator and 1-3% of an auxiliary agent. According to a common paint preparation method used by a technicist in the field, the above materials are made into a spraying waterborne UV-curable matt paint. The paint is automatically sprayed by equipment or manually onto a base material. Therefore, VOC emission can be greatly reduced and production efficiency can be enhanced. By infrared curing and then UV light curing, excellent leveling property can be obtained, and surface effect of PU paint and hardness and scratch resistance of UV can be achieved.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a water-based ultraviolet light curing matte color paint for spraying with mixed gas. Background technique [0002] UV-curable coatings have achieved rapid development since they were industrialized in the paper industry and bamboo wood flooring industry due to their unparalleled advantages of low pollution, fast curing, and high temperature avoidance compared with traditional coatings. Air-mixed spraying water-based UV paint is a water-based light-curing paint. It is a furniture paint that is rarely used at present. Its main features are: friendly to the environment, after strong ultraviolet light curing treatment, stable color and long-lasting. Therefore, it is widely used in furniture coating, and has been used in large-area furniture in recent years. However, in terms of spraying matte topcoats, traditional UV is better than curing speed too fast, or adding solvents to achie...
