Abstract

The invention discloses an emulsion type waterproof corrosion-resistant acrylate exterior wall coating, comprising the following raw materials by weight: 50 to 60 parts of a base material, 5 to 15 parts of an alcohol-ester 12 film-forming additive and 30 to 40 parts of an accessory material. The base material comprises the following raw materials by weight: 5 to 10 parts of a drying oil alkyd resin, 50 to 60 parts of acrylic emulsion, 30 to 40 parts of silica sol, 2 to 6 parts of a coupling agent and 1 to 4 parts of sodium butylnaphthalenesulfonate. The accessory material comprises the following raw materials by weight: 20 to 25 parts of borax, 15 to 20 parts of light calcium carbonate, 15 to 20 parts of titanium dioxide, 18 to 23 parts of wollastonite powder, 5 to 10 parts of nanometer zinc oxide, 0.5 to 1 part of polyvinylpyrrolidone, 0.5 to 1.5 parts of an antifoaming agent, 0.8 to 1.3 parts of carboxymethylcellulose sodium, 1 to 2 parts of 1,2-benzoisothiazole-3-one, 1 to 1.3 parts of ammonia water, 10 to 15 parts of water and 2 to 5 parts of methyl nylon acid ester. The emulsion type waterproof corrosion-resistant acrylate exterior wall coating has excellent waterproof performance, good corrosion resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of acrylate exterior wall paint, in particular to an emulsion-type waterproof and corrosion-resistant acrylate exterior wall paint. Background technique [0002] The variety of anti-corrosion coatings in my country has developed extremely rapidly. At present, many anti-corrosion coatings with excellent performance have been developed, such as high-temperature anti-corrosion coatings, anti-static anti-corrosion coatings, high-elastic anti-corrosion coatings, non-toxic anti-corrosion coatings and many other varieties. With the development of high-performance anti-corrosion coatings The continuous development and application of anti-corrosion coatings has important scientific value and social value. Although anti-corrosion coatings are developing rapidly, the corrosion resistance and waterproof performance of anti-corrosion coatings still need to be further improved. Contents of the invention [0003] The inv...
