Problems solved by technology

Traditional solvent-based acrylic paints will release a large amount of volatile organic compounds during the film formation process, causing pollution to the environment
However, there are still many deficiencies in water-based acrylic coatings, such as low hardness of the coating film, poor weather resistance and poor adhesion, which hinder its development.

Abstract

The present invention discloses a high-hardness and high-wear-resistance acrylate water-based paint, which comprises a component A and a component B. The component A comprises the following raw materials: aqueous acrylate emulsion, alkyd resin, polyhydroxy unsaturated polyester resin, phenolic resin, nitrocellulose, silane coupling agent KH-560 modified nano-silicon dioxide, calcium carbonate whisker, talc, dipropylene glycol methyl ether, dipropylene glycol butyl ether, anti-settling agent, wetting agent and anti-foaming agent. The component B comprises the following raw materials: fully-methoxylated melamine resin, 3, 5-dimethyl-2-aminobenzoic acid, flatting agent and de-ionized water. The high-hardness and high-wear-resistance acrylate water-based paint is high in hardness, good in wear resistance, excellent in water resistance and heat resistance, and long in service life.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-hardness and high-wear-resistant acrylate water-based paint. Background technique [0002] Acrylic coatings have high hardness, excellent gloss and chemical resistance after film formation, and are low in cost, and are widely used in the automotive, construction and furniture industries. Traditional solvent-based acrylic paints release a large amount of volatile organic compounds during the film-forming process, causing pollution to the environment. However, there are still many deficiencies in water-based acrylic coatings, such as low coating film hardness, poor weather resistance and poor adhesion, which hinder its development. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a high-hardness and high-wear-resistant acrylate water-based paint, which has high hardness, good wear resistance, ...
