Crystal water-permeability UV (Ultraviolet) matte top-coat

Abstract

The invention provides a crystal water-permeability UV (Ultraviolet) matte top-coat. The high transparency waterborne UV spraying matter top-coat is prepared from a waterborne polyurethane-acrylic acid copolymer with an UV curing characteristic, high transparency extinction powder and wax dispersion, has the environmental protection property of waterborne wood paint, the rapid drying curing performance of oil UV paint and excellent paint film mechanical property, can be used for overcoming the defects of difficulty in extinction, poor transparency and the like existing in UV paint and is the crystal water-permeability UV matte top-coat with the high transparency, which is widely applied to wood doors, office furniture, panel-type furniture and children furniture. The construction manner of the high transparency waterborne UV spraying matter top-coat is spraying. The detection and the trail prove that the crystal water-permeability UV matte top-coat has the advantages of fast curing speed, high production efficiency and environmental protection, and a coating has a fine and smooth surface, uniform luster, excellent transparency, good hand feeling, abrasion resistance and scratch resistance.

Description

technical field [0001] The invention relates to a crystal-transparent UV matte varnish, which is prepared by reacting and mixing water-based polyurethane-acrylate copolymers with UV curing characteristics, a photoinitiator and various auxiliary agents, and the construction method is spraying. Background technique [0002] UV light-curable wood paint, commonly known as UV-curable wood paint, and water-based wood paint have always been considered as the mainstream direction of environmental protection development of wood paint. Compared with water-based wood lacquers, UV light-cured wood lacquers can better meet the chemical corrosion resistance in terms of performance, and their paint films are also more excellent, but the excessive viscosity and the irritation and toxicity of reactive diluents make them less environmentally friendly. At the same time, there are defects such as difficult matting and poor transparency in matte series products. In contrast, water-based wood la...

Problems solved by technology

Compared with water-based wood lacquers, UV light-cured wood lacquers can better meet the chemical corrosion resistance in terms of performance, and their paint films are also more excellent, but the excessive viscosity and the irritation and toxicity of reactive diluents make them less environmentally friendly. At the same time, there are defects such as difficult extinction and poor transparency in matte series products

On the other hand, although water-based wood paint is excellent in environmental performance, there is still room for improvement in the appearance and hardness of the paint film.
