Problems solved by technology

Water-based metal anti-rust white paint is different from other colors of anti-rust paint. Titanium dioxide itself has no anti-corrosion function, and it is not allowed to add colored and heavy metal anti-rust pigments. Relying on resin alone to maintain anti-corrosion performance is not good, so it has anti-corrosion performance Poor, poor hiding power, easy yellowing and other key problems cannot meet the anti-corrosion requirements

Abstract

The invention discloses water-based metal rust-proof white paint and a preparation method thereof, and belongs to the field of coating. According to the invention, water serves as a diluent; water-soluble resin which is formed by copolymerizing an acrylate monomer and a self-crosslinking functional monomer is selected; high-covering-power titanium dioxide imported from Japan, and high-performance corrosion-resistant fillers, a salt-mist-resistant agent, a flash-rust-resistant agent and a silane coupling agent are provided; the gel content is increased by a crosslinking molecular chain; the coating is subjected to complex reaction on the surface of metal to form a corrosion-resistant complex; the resin has an ultraviolet-stable monomer structure and a group with a special function, high adhesive force and waterproofness, so that the coating has excellent weather resistance and water resistance, good covering powder, no yellowing phenomenon, good adhesive force and high hardness, does not add any toxic corrosion-resistant fillers and aids, and is safe, environment-friendly and convenient to construct.

Description

technical field [0001] The invention relates to a water-based metal anti-rust paint, in particular to a water-based metal anti-rust white paint and a preparation method thereof. Background technique [0002] Metal anticorrosion has always been concerned and valued by all walks of life. In recent years, with the rapid development of economic construction and science and technology, there are more and more requirements and demands for anti-corrosion. Most of the traditional anti-corrosion paints on the market are iron red, black and gray, and the types and performances are far from meeting the needs. Water-based metal anti-rust white paint is different from other colors of anti-rust paint. Titanium dioxide itself has no anti-corrosion function, and it is not allowed to add colored and heavy metal anti-rust pigments. Relying on resin alone to maintain anti-corrosion performance is not good, so it has anti-corrosion performance Poor, poor hiding power, easy yellowing and other...
