Abstract

The invention discloses an anti-cracking elastic emulsion paint. The anti-cracking elastic emulsion paint comprises, by weight, 50 to 60 parts of water, 18 to 25 parts of a high elasticity acrylic emulsion, 7 to 12 parts of a modification film forming agent, 6 to 10 parts of heavy calcium carbonate, 4 to 6 parts of mica powder, 1 to 2 parts of an anti-cracking agent, 0.2 to 0.3 part of sodium dodecyl sulfate, 1 to 2 parts of casein, 1 to 2 parts of podocarpus macrophyllus powder, 0.5 to 1 part of propylene glycol, and 0.1 to 0.2 part of a bactericide. The anti-cracking elastic emulsion paint possesses excellent anti-cracking performance, and high elasticity, toughness, insulating properties, and high temperature resistance.

Description

technical field [0001] The invention relates to the technical field of latex paint, in particular to an anti-crack elastic latex paint. Background technique [0002] Latex paint is a common name for latex paint. It was born in the middle and late 1970s. It is a large class of synthetic resin emulsion paint represented by acrylate copolymer emulsion. It uses synthetic resin emulsion as the base material, and the filler is ground and dispersed. A paint refined by adding various additives. Latex paint has many advantages that are different from traditional wall paints, such as easy to paint, fast drying, water-resistant paint film, and good scrub resistance. In my country, it is customary for people to use synthetic resin emulsion as the base material, use water as the dispersion medium, add pigments, fillers (also known as body pigments) and additives, and the paint made through a certain process is called latex paint, also called latex. coating. [0003] However, in the pri...
