Abstract

The present invention discloses a wear-resistance and corrosion-resistance polyurethane paint, which is prepared from the raw materials such as polyurethane, silicon dioxide, titanium dioxide, asphalt, nanometer aluminum oxide, zirconium oxide, silicon nitride, talc powder, a phenolic resin, butyl methacrylate, an epoxy resin and a dispersing auxiliary agent, wherein the dispersing auxiliary agent is prepared from diatomaceous earth, jade powder, a silane coupling agent, acrylate and pentaerythritol triacrylate. According to the present invention, the paint has characteristics of extremely strong corrosion resistance, saline resistance, alkali resistance, good metal protection effect, high hardness, wear resistance, compression resistance, substantially-improved paint protection effect, strong paint stability, easy use, and easy operation.

Description

technical field [0001] The invention relates to the technical field of paint production, in particular to a wear-resistant and corrosion-resistant polyurethane paint. Background technique [0002] As an important coating, polyurethane paint has good corrosion resistance and has been widely used in home decoration and furniture coating. Polyurethane paint has properties such as high hardness, plump paint film, and good wear resistance, and is widely used in cabinet furniture, metal protection, etc. However, general one-component polyurethane paints are still lacking in hardness and wear resistance. As time goes by, polyurethane paints on furniture and metal surfaces are easily scratched and polluted by corrosion. Contents of the invention [0003] The object of the present invention is to provide a kind of wear-resistant and corrosion-resistant polyurethane paint that has good protective effect on metal and furniture surface, to solve the problems raised in the above-menti...
