Abstract

The invention provides a polyurethane matt varnish for benzene-free odor-less furniture, which is composed of a main agent, a curing agent and a diluent. The main agent comprises 66.5-75.5% of hydroxyacrylic resin, 16.0-25.0% of solvent, 0.1-0.3% of defoarming agent, 0.05-0.1% of flatting agent, 0.1-0.5% of anti-settling agent, 0.1-0.5% of dispersing agent, and 4-8% of delustering agent; the curing agent comprises40.0-50.0% of toluene diisocyanate tripolymer, 20.0-30.0% of toluene diisocyanate-trimethylolpropane affixture, and 20.0-30.0% of butyl acetate; the diluent comprises 60.0-70.0% of butyl acetate, 15.0-20.0% of cyclohexanone, and 15.0-25.0% of propylene glycol methyl ether acetate. The product of the invention is favorable for construction, and no odor exists after the construction of the previous night.

Description

technical field [0001] The invention relates to a polyurethane matte clear finish paint. Background technique [0002] At present, with the improvement of people's material and cultural living standards, home furniture is no longer limited to general aesthetics and decorative effects, but more requirements are placed on health and comfort. Although alkyd polyurethane paints for furniture on the market have good decorative effects, they all have odors that are difficult to eliminate, have a long residual time of solvents, and contain benzene substances that are harmful to human health. Therefore, it is particularly necessary to develop new furniture paint products that are benzene-free, odor-free, and harmless to human health, and have become a hot spot and development direction in the market. However, most of the odor-cleaning products launched by many manufacturers currently use methods such as adding flavors and deodorants, which cannot fundamentally solve the problem. ...
