Abstract

The invention discloses high transparency scratch-resisting matt clear paint which is composed of a host agent, a curing agent and a diluent agent. The host agent comprises 65.5 % - 75.5% of short oil alkyd resins, 16 % - 25 % of solvent, 0.1 % - 0.3 % of antifoaming agents, 0.1 % - 0.3 % of flatting agents, 0.1 % - 0.5 % of anti-settling agents, 0.1 % - 0.3 % of dispersing agents, 1 % - 3 % of scratch-resisting assistant agents, and 4 % - 8 % of delustering agents. The curing agent comprises 40 % - 50 % of toluene diisocynate (TDI) trimer, 10 % - 20 % of TDI- hexamethylene diisocyanate (HDI) mixed trimer, 20 % - 30 % of TDI- trimethylolpropane adduct, and 20 % - 30 % of butyl acetate. The diluent agent comprises 40 % - 50 % of butyl acetate, 20 % - 30 % of dimethylbenzene, and 20 % - 30 % of propylene glycol methyl ether acetate. The high transparency scratch-resisting matt clear paint is good in transparency and scratch-resisting performance, and is easy to process.

Description

technical field [0001] The invention relates to a polyurethane matte clear finish paint. technical background [0002] At present, with the improvement of people's material and cultural living standards, the requirements for furniture are no longer limited to temporary decorative and aesthetic effects, but higher requirements are put forward for the durability of decorative and aesthetic effects of furniture, especially for office furniture. Scratches on furniture surfaces and transparency of paint films. The polyurethane paints used in the market, although ordinary products have good transparency, have average scratch resistance; and anti-scratch products generally use glass powder to improve the scratch resistance of the paint film and make the paint film transparent. There is a contradiction between the two. Contents of the invention [0003] The object of the present invention is a high-transparency anti-scratch matte clear finish paint, to overcome the above-mention...
