Embodiment 1

[0011] Embodiment 1 of the present invention provides an environmentally friendly latex paint, which is composed of the following raw materials in parts by weight: 5 parts of vinyl acetate-ethylene copolymer emulsion, 15 parts of polyvinyl acetate, 2,2,4-trimethyl 3 parts of 1,3-pentanediol monoisobutyrate, 10 parts of wollastonite powder, 8 parts of titanium dioxide, 0.5 parts of polyvinylpyrrolidone, 1 part of sodium tetraborate, and 15 parts of water. The latex paint provided in Example 1 has a short drying time of about 35 minutes, good alkali resistance without abnormality for 24 hours, and good stucco resistance, no abnormality after 2500 times of painting, far higher than the standard requirement of 1000 times.

Embodiment 2

[0013] Embodiment 2 of the present invention provides an environment-friendly latex paint, which is composed of the following raw materials in parts by weight: 5 parts of vinyl acetate-ethylene copolymer emulsion, 15 parts of polyvinyl acetate, 2,2,4-trimethyl 3 parts of 1,3-pentanediol monoisobutyrate, 10 parts of wollastonite powder, 8 parts of calcium carbonate, 0.5 parts of polyacrylamide, 1 part of Kathon, and 15 parts of water. The latex paint provided in Example 2 has a short drying time of about 35 minutes, good alkali resistance without abnormality for 24 hours, and good stucco resistance. There is no abnormality after 2500 times of painting, which is far higher than the standard requirement of 1000 times.

Embodiment 3

[0015] Embodiment 3 of the present invention provides an environment-friendly latex paint, which is composed of the following raw materials in parts by weight: 6 parts of vinyl acetate-ethylene copolymer emulsion, 20 parts of polyvinyl acetate, 2,2,4-trimethyl 5 parts of base 1,3-pentanediol monoisobutyrate, 12 parts of wollastonite powder, 10 parts of titanium dioxide, 1.5 parts of thickener, 3 parts of preservative, and 20 parts of water. In the present embodiment 3, preservative is Kathon, and thickener is methyl cellulose.

[0016] The latex paint provided in Example 3 has a short drying time of about 40 minutes, good alkali resistance without abnormality for 24 hours, and good stucco resistance, no abnormality after 2500 times of painting, far higher than the standard requirement of 1000 times.

Abstract

The invention provides an environment-friendly type latex paint composed of the following raw materials in parts by weight: 5-8 parts of a vinyl acetate-ethylene copolymerized emulsion, 5-20 parts of polyvinyl acetate, 3-7 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 6-15 parts of a wollastonite powder, 7-15 parts of titanium dioxide or calcium carbonate, 0-2 parts of a thickening agent, 1-5 parts of a preservative, and 12-25 parts of water. The latex paint provided by the invention has the advantages of high environment-friendly performance, smooth and full appearance of a paint film, short drying time during brushing, uniform and continuous paint film, no flowing and no air bubbles; with addition of the wollastonite powder, the expansion capacity of the paint is increased, the oil absorption amount can be reduced, the paint film surface is prevented from generating cracks, and the corrosion resistance ability is enhanced; the latex paint provided by the invention has good alkali resistance and good painting resistance.

Description

technical field [0001] The invention belongs to the field of paint building materials, in particular to an environment-friendly latex paint. Background technique [0002] After China put forward the strategic goal of urban development as the core, various infrastructure constructions are carried out in full swing. Enhances the aesthetics of the interior and exterior surfaces of buildings and can increase the service life of buildings. Latex paint has many advantages different from traditional wall coatings, such as easy to brush, dry quickly, no fire hazard, etc.; but the existing latex paint has poor stucco resistance and poor alkali resistance. Contents of the invention [0003] The problem to be solved by the present invention is to provide an environment-friendly latex paint with short drying time, good alkali resistance and good stucco resistance. [0004] In order to solve the above technical problems, the technical solution adopted in the present invention is: an ...
