Abstract

The invention discloses a formula of nano silicon carbide powder coating and a preparation method thereof, which comprises a component A, a component B and a component C, wherein the component A comprises an acrylic emulsion, a nanometer silicon carbide powder, a styrene-butadiene rubber and a modified high chlorinated polyethylene resin; component B comprises: feldspar powder, carborundum, ceramic micropowder, mica powder, high temperature resistant pigment, calcium carbonate, talcum powder, barium sulfate, asphalt and white cement; the composition C comprises a dispersing agent, a defoamingagent, a wetting agent, a sterilization mildewproof agent, a leveling agent, a cross-linking agent, a wetting agent, a slip-adding assistant, a film-forming auxiliary agent, a thickening agent and water; the coating has the characteristics of excellent pollution resistance, salt spray resistance, ageing resistance and wear resistance, in which, scratch resistance, adhesion and thermal shock resistance are good, the coating has excellent impact resistance, flexibility, not-easy-to crack and stable chemical stability, is not easy to be corroded by strong acid, strong alkali, strong chlorinatingagent, etc., with high service life, capable of anti-virus and anti-mildew with good combustion performance.

Description

Technical field: [0001] The invention relates to the field of coatings, in particular to a formulation of nano-silicon carbide powder coatings and a preparation method thereof. Background technique: [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Additives, viscous liquids prepared with organic solvents or water. Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. There are four main functions: protection, decoration, concealing product defects and other special functions, and enhancing the value of the product. However, the existing coatings are poor in stain resistance, salt spray resistance, aging resistance, abrasion resistance, scratch resistance, adhesion, and thermal shock re...
