Problems solved by technology

[0002] At present, polyurethane paint is more popular for wood coating, but there are many disadvantages in polyurethane paint: the polyurethane paint film using aromatic isocyanate as raw material has poor durability, easy yellowing and chalking, and aliphatic isocyanate is used as the main material. Although the raw polyurethane paint is not easy to yellow, it is slow in drying speed and

Abstract

Disclosed is urea formaldehyde/ alkyd woodenware half-matte top finish, comprising half-matte top finish and lacquer mate; the weight ratio of half-matte top finish and lacquer-mate during the construction is 1:0.3-0.4; wherein the half-matte top finish is composed of bean oil, or alkyd at mediate or short oil length modified from behenic acid, urea resin etherified by butanol, polycarboxylic acid dispersant, aerosol flatting agent, Tissuemat E anti-settling agent, polyether organosilicone leveling agent, aralkyl organosilicone leveling agent, non-siliceous foam killer and normal butanol; the lacquer-mate is composed of paratoluenesulfonic acid, normal butanol and thinner. The top finish is environment-friendly and energy-saving and suits the requirements in the work of lacquering woodenware. The top finish is excellent in performance and the lacquer film is of the same or even better performance than polyurethane lacquer.

Description

technical field [0001] The invention relates to a naturally-drying finish paint for woodware coating, which belongs to the technical field of coatings. Background technique [0002] At present, polyurethane paint is more popular for wood coating, but there are many disadvantages in polyurethane paint: the polyurethane paint film using aromatic isocyanate as raw material has poor durability, easy yellowing and chalking, and aliphatic isocyanate is used as the main material. Although the raw polyurethane paint is not easy to yellow, it is slow in drying speed and expensive, and its application on wood is limited; polyurethane paint contains a large amount of organic volatile solvents (especially triphenyl) and toxic free isocyanate, which pollutes the air and harms the builders. It will cause certain harm to the health of householders, and the volatilization of a large amount of organic solvents will also cause a waste of petroleum product resources.
