Problems solved by technology

[0004] After the polyurethane primer is used to match the polyurethane topcoat, it is prone to collapse, poor fullness, scratch resistance and hardness, and the coating environment produces a large amount of VOC, which affects the health of workers
[0005] The unsaturated polyester primer matched with the polyurethane topcoat can improve the film hardness, scratch resistance, and collapse to a certain extent, but a large amount of VOC will be generated when the topcoat is sprayed

Abstract

The invention discloses a high solid anti-scratching unsaturated polyester matte top coat for coating wooden products. The top coat comprises the following components according to a ratio: the ratio of a top coat main agent to an accelerator to an initiator to a reactive diluent is equal to 100:(1-2):(1-2):(25-30), wherein the top coat main agent comprises the following components in parts by weight: 65-75 parts of unsaturated polyester resin, 5-7 parts of extinction powder, 5-8 parts of glass powder, 2-3 parts of an addition agent and 13-17 parts of reactive diluent. The accelerator is a cobalt iso-octoate solution, the initiator is a methyl ethyl ketone peroxide solution, and the diluent is the reactive diluent. Compared with a polyurethane top coat which is widely applied to the market, the top coat has the characteristics of no solvent (no volatile organic compounds (VOC) emission), high richness, good fallibility, high hardness, excellent scratching resistance and high coating efficiency.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a wood coating, in particular to a high-solid, anti-scratch unsaturated polyester matte varnish for coating wood products. Background technique [0002] Office furniture paint has been applied to various office furniture with high fullness and scratch resistance. [0003] At present, the well-known coating of office furniture is mainly based on polyurethane primer matching polyurethane topcoat, or unsaturated polyester primer matching polyurethane topcoat. [0004] After the polyurethane primer is used to match the polyurethane topcoat, it is prone to collapse, poor fullness, scratch resistance and poor hardness, and the coating environment produces a large amount of VOC, which affects the health of workers. [0005] The unsaturated polyester primer matched with the polyurethane topcoat can improve the film hardness, scratch resistance, and collapse properties to a certain extent...
