preparation example Construction

[0017] A preparation method of a light anti-corrosion latex paint, comprising the following steps: first adding 0.5-5 parts by mass of water, 0.015-1 part by mass of a defoamer, and 0.1-3 parts by mass of a dispersant into a batching tank and mixing evenly, and then Add 0.1-3 parts by mass of thickener and stir evenly; then add 0-30 parts of pigment and grind for 10-20 minutes; then add 1-10 parts of film-forming aid, 0.1-5 parts of co-solvent, 70 parts of film-forming substances, stirred evenly, then added 0-1 parts by mass of antifungal agent, 0-1 parts by mass of preservative, pH regulator of 0-1 parts by mass, filtered, packaged to obtain light anti-corrosion latex paint finished product.

[0018] The film-forming substance is an aqueous acrylic emulsion, preferably HD1092 aqueous acrylic emulsion. The film-forming aid is one of Texanol ester alcohol, LusolvanFBH, Coasol, DBE-IB, DPNB, Dowanol pph. The co-solvent includes one of 1,2-propanediol and absolute ethanol. The...

Abstract

The invention discloses a light anti-corrosion latex paint, which is composed of the following raw materials in parts by mass: 30-70 parts of water-based acrylic emulsion, 0-30 parts of pigment, 1-10 parts of film-forming aid, 0.1-70 parts of 5 parts of co-solvent, 0.1-3 parts of dispersant, 0.015-1 part of defoamer, 0.1-3 parts of thickener, 0-1 part of pH regulator, 0-1 part of antifungal agent, 0-1 part of preservative, 0.5-5 parts of water. The light anti-corrosion latex paint provided by the invention has the characteristics of excellent paint film adhesion, good water resistance, good hardness, etc.; the coating method is convenient, and is completely the same as the common latex paint.

Description

Technical field [0001] The present invention involves a light anticorrosive milky paint. Background technique [0002] With the development of the coating industry and coating towards low pollution, the development of coatings to the direction of environmental protection low VOC water -based coatings has become an inevitable trend.In the anticorrosive industry, the loss caused by metal corrosion is very serious. According to the perspective of thermodynamics, most metals have a tendency to turn into an oxidation state with the surrounding medium. Therefore, metal corrosion is a natural trend, which is inevitable.Metal corrosion not only brings huge direct losses to the metal material itself, but also the loss caused by the damage of the component is much greater than the loss of the metal itself.As a result, in order to reduce the losses caused by metal corrosion, the cause of corrosion and its protection methods are necessary; and the protection of metal materials with coatings ...
