Abstract

The invention relates to the technical field of metal rust prevention, and in particular relates to a high-glossiness metal anti-rust coating used for machinery. The coating includes the following components: a styrene-acrylic emulsion, an acrylic resin emulsion, iron oxide red, barium sulfate, wax powder, a defoaming agent, modified titanium dioxide, an corrosion-resistant auxiliary agent, a pigment, a film-forming auxiliary agent, aluminum triphosphate, deionized water, a dispersant and a coupling agent, wherein the barium sulfate has 700-800-mesh fineness; the defoaming agent is polydimethylsiloxane or tributyl phosphate; the film-forming auxiliary agent is 2-butoxy ethanol or 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate; the pigment is an ST-2 composite anti-rust pigment; the dispersant is a polyisobutylene diacid salt; and the coupling agent is epoxy silane coupling agent KH-560. The anti-rust coating provided by the invention has excellent anti-oxidation performance, good protection performance and a good film-forming effect; and a protective coating layer has high glossiness and is very beautiful.

Description

technical field [0001] The invention relates to the technical field of metal antirust, in particular to a high-gloss metal antirust paint for machinery. Background technique [0002] The parts of mechanical equipment are mainly made of metal. In order to prevent the metal material from oxidizing and rusting during use, it is necessary to spray anti-rust paint on the surface of the equipment. The conventional anti-rust paint is roughly oily and water-based. Oil-based antirust paint is easy to use and low in price, but because it contains toxic substances such as nitrite and chromate, it is harmful to operators. Rust requirements. The water-based metal anti-rust paint is made of metal strong chelating agent phytate as the main component, and is compounded with several other water-based additives. After use, a dense protective film can be formed, which can effectively inhibit the corrosion of metals. [0003] However, conventional water-based antirust paints have poor gloss ...
