Abstract

The invention relates to the technical field of painting, particularly to a highly-adhesive elastic emulsion paint. The highly-adhesive elastic emulsion paint is composed of pure acrylic emulsion, styrene-acrylic emulsion, inorganic filler, compound thickening agent, polytetrafluoroethylene-polyurethane copolymer, polyacrylamide, nanometer titanium dioxide, preservative, defoamer, leveling agent and deionized water, wherein the compound thickening agent is a special combination prepared by compounding materials such as mucopolysaccharides, modified cellulose and modified starch; the organic filler is a mixture of titanium dioxide, talcum powder and light calcium carbonate; the preservative is 1, 2-benzisothiazolin-3-one, methylisothiazolinone or 5-chloro-2-methyl-4-isothiazolinone-3-one. The highly-adhesive elastic emulsion paint is high in adhesiveness and easy to dry and cure and can form coating high in elasticity, strength and washing resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an elastic latex paint with high adhesion. Background technique [0002] Emulsion paint (Emulsion Paint.), also known as synthetic resin emulsion paint, is a kind of organic paint. It is a kind of water-based paint formulated with synthetic resin emulsion as the base material and added with pigments, fillers and various additives. According to different production raw materials, latex paint mainly includes polyvinyl acetate latex paint, ethylene-propylene latex paint, pure acrylic latex paint, styrene-acrylic latex paint and other varieties. According to the different application environment of the product, it is divided into two types: interior wall latex paint and exterior wall latex paint. According to the gloss effect of the decoration, it can be divided into dull, matte, semi-gloss, mercerized and glossy. Latex paint has many advantages that are different from traditional...
