A kind of elastic epoxy polyurethane matte wood floor paint and preparation method thereof

Abstract

The invention relates to an elastic epoxy polyurethane matte wood floor paint and a preparation method thereof. The elastic epoxy polyurethane matte wood floor paint is formed by mixing a hydroxyl component and an NCO component at a mass ratio of 1:0.8-1.2 , wherein the components and parts by weight of the hydroxyl component are as follows: 70-80 parts of epoxy resin, 0.1-0.5 parts of dispersant, 0.1-0.9 parts of fumed silica, 0.3-0.9 parts of polyethylene wax powder, poly Amide wax slurry 0.1-1 part, matting powder 0.1-0.9 part, xylene 4-20 part, propylene glycol methyl ether acetate 4-20 part, defoamer 0.1-0.5 part, leveling agent 0.1-0.5 part, dry Agent 0.1-0.5 parts; wherein the NCO component is the curing agent. The elastic epoxy polyurethane matte wood floor paint prepared by the invention has the characteristics of high strength, high elasticity, high wear resistance, impact resistance and good adhesion.

Description

technical field

[0001] The invention relates to a matte varnish used on home improvement wooden floors, in particular to an elastic epoxy polyurethane matte wooden floor paint and a preparation method thereof. Background technique

[0002] Polyurethane coating is a kind of coating with excellent comprehensive performance, which is widely used in wood decoration and wooden floor. Since wooden furniture or wooden floors are easily scratched and have poor wear resistance during the process of manufacture and use, it is very necessary to improve the wear resistance. Therefore, the wear resistance, impact resistance and adhesion of the existing polyurethane wood floor paint need to be further improved. Contents of the invention

[0003] The purpose of the present invention is to provide a kind of elastic epoxy polyurethane matte wood floor paint and preparation method thereof in order to overcome the deficiencies in the prior art, the elastic epoxy polyurethane matte wood floo...
