Water-soluble antirust insulating paint and preparation method therefor

Abstract

The invention provides a water-soluble antirust insulating paint and a preparation method therefor. The water-soluble antirust insulating paint disclosed by the invention consists of the following components in parts by weight: 18-25 parts of an antirust base material, 20-30 parts of an insulation base material, 2-4 parts of a rust transforming agent , 2-3 parts of a passivation preservative, 0.5-0.9 part of a drying agent, 1.3-1.6 parts of an auxiliary, 20-30 parts of a pigment filling, and 30-40 parts of water, wherein the base material is the mixture of nonsoap aqueous acrylic ester, epoxy resin and polyurethane; the rust transforming agent consists of mica ferric oxide and phosphoric acid; the phosphoric acid is industrial hydrochloric acid of which the content is 85%; the weight ratio of the mica ferric oxide to the phosphoric acid is 1:1-1.5. The antirust paint is scientific and reasonable in formula, can use water to replace petroleum and benzene as a solvent, and has dual functions of rust removal and rust prevention, so that the antirust paint can be widely used for anticorrosive construction and anticorrosive construction of steel structures.

Description

technical field [0001] The invention relates to antirust paint technology, in particular to a water-soluble antirust insulating paint and a preparation method thereof. Background technique [0002] With the development of the economy, the amount of steel used and the losses caused by surface corrosion are increasing day by day. According to statistics, the annual economic loss caused by metal corrosion in my country is as high as 1 billion to 15 billion yuan. Therefore, a large amount of antirust paint for steel surfaces is needed. At present, the antirust paints used in China are mainly solvent-based iron red antirust paints that use petroleum and benzene solvents as thinners, and alkyd and phenolic resins as base materials. This anti-rust paint is not only costly, but also toxic and flammable. It has only a single anti-rust function. It needs to be manually derusted before use, and the pre-treatment is troublesome. [0003] On the other hand, with the development of high...

Problems solved by technology

This kind of anti-rust paint is not only costly, but also toxic and flammable. It has only a single anti-rust function. It needs heavy manual derusting before use, and the pre-treatment is troublesome.

[0003] On the other hand, with the development of high-tech industries such as aviation, aerospace, electronics and nuclear energy, the heat resistance and insulation requirements of paints and coatings will become higher and higher. The thermal effect is very good, but none of them has anti-rust function. Therefore, it is absolutely necessary to develop new anti-rust insulating paints and coatings, and it has far-reaching significance
