Abstract

The invention discloses antirust paint for valve surface treatment. The antirust paint is prepared from the following raw materials in parts by weight: 80-100 parts of polypropylene alcohol emulsion,20-30 parts of water-based polyacrylic resin, 20-30 parts of o-cresol formaldehyde epoxy resin, 5-10 parts of a dispersing agent, 0.5-1.5 parts of a thickener, 2-4 parts of a defoamer, 3-5 parts of nano-silica and 3-5 parts of ferric oxide. By adopting the technical scheme, the antirust paint for valve surface treatment has the beneficial effects that the antirust paint is excellent in physical and chemical properties, fast in drying speed, good in weather resistance, high in transparency, good in rust prevention performance, oil resistance, water resistance, salt water resistance, solvent resistance and adhesion, dense and tough in paint film, high in hardness, convenient for construction and free from environmental pollution. In addition, the antirust paint is supported by the environment-friendly raw materials, thus being non-toxic, non-polluting and environmentally safe.

Description

technical field [0001] The invention relates to an antirust paint, in particular to an antirust paint for valve surface treatment. Background technique [0002] Antirust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea water, etc. Mainly divided into two categories of physical and chemical antirust paint. The former relies on the proper coordination of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc.; the latter relies on the chemical antirust effect of antirust pigments, such as red lead , Zinc yellow antirust paint, etc. Used for rust prevention of bridges, ships, pipes and other metals. Anti-rust paint is favored by people because of its anti-rust effect, but the anti-rust paint currently on the market contains many toxic substances and is not environmentally friendly.
