Abstract

The invention discloses a waterproof corrosion-resistant acrylate exterior wall paint, comprising the following raw materials by weight: 20 to 30% of acrylate emulsion, 20 to 30% of styrene acrylic emulsion, 40 to 50% of an accessory material and 2 to 6% of propylene glycol monomethyl ether acetate. The acrylate emulsion is prepared through the following process procedures: placing 40 to 50 parts by weight of CB-700 acrylic acid emulsion and 40 to 50 parts by weight of a silica sol in a reactor; carrying out high-speed uniform stirring at 70 to 75 DEG C; and then adding 2 to 5 parts of a coupling agent and 2 to 4 parts of modified sodium laurylsulfate and carrying out uniform stirring. The accessory material comprises the following raw materials by weight: 5 to 15 parts of titanium trioxide, 5 to 8 parts of heavy calcium carbonate, 20 to 25 parts of titanium dioxide, 5 to 15 parts of wollastonite powder, 0.5 to 1 part of a wetting dispersant, 1.5 to 2 parts of an antifoaming agent, 0.8 to 1.5 parts of carboxymethyl cellulose, 1 to 2.5 parts of 1,2-benzoisothiazole-3-one, 1 to 1.3 parts of ammonia water, 5 to 10 parts of water and 5 to 10 parts of methyl nylon acid ester. The waterproof corrosion-resistant acrylate exterior wall paint has excellent waterproof performance, good corrosion resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of acrylic paints, in particular to a waterproof and corrosion-resistant acrylic paint for exterior walls. 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 invention provides a waterpr...
