Anticorrosive external wall latex paint

Abstract

The invention discloses an anticorrosive external wall latex paint which is composed of the following components in parts by mass: 5-7 parts of styrene-acrylic emulsion, 0.5-1 part of thickener, 6-9 parts of silicon defoaming agent, 30-40 parts of deionized water, 6-8 parts of titanium white, 30-38 parts of hydroxyethyl cellulose, 5-7 parts of wollastonite powder, 8-10 parts of sodium hexametaphosphate, 9-18 parts of hollow microbead emulsion, 10-15 parts of bentonite, 0.4-0.5 part of wetting and dispersing agent, 0.1-0.3 part of anhydrous aluminium silicate, 0.5-1 part of preservative, 8-17 parts of kaolin, 1-4 parts of ethanediol, 8-17 parts of lignin and 0.7-2.0 parts of film forming aid. The anticorrosive external wall latex paint disclosed by the invention has the advantages of favorable water resistance, favorable alkali resistance, favorable corrosion resistance, pollution resistance, high wear resistance and high adhesiveness.

Description

technical field [0001] The invention relates to an anti-corrosion exterior wall latex paint. Background technique [0002] Latex paint is a kind of paint with polymer emulsion as film-forming substance. It is easy to construct, has little environmental pollution, and is widely used. Latex paint belongs to building materials, and its mechanical properties, antifouling properties, wear resistance, health properties, flexibility, radiation resistance, waterproof performance, appearance performance, production, construction performance and environmental protection performance are usually considered. At present, the latex paint for exterior walls has poor stain resistance, which seriously affects the appearance and other properties; poor wear resistance, prone to scratches, etc.; poor adhesion, easy to fall off. Simultaneously, current anti-corrosion latex paint has shortcomings such as poor flexibility of the paint layer, large void ratio, excessive paint film thickness, etc., ...

AI Technical Summary

Problems solved by technology

At present, the latex paint for exterior walls has poor stain resistance, which seriously affects the appearance and other properties; poor wear resistance, prone to scratches, etc.; poor adhesion, easy to fall off

At the same time, the current anti-corrosion latex paint has disadvantages such as poor flexibility of the paint layer, large void ratio, and excessive film thickness, which cannot meet the requirements of heavy-duty anti-corrosion.
