Abstract

The invention discloses acrylic acid outer wall latex paint and a preparation process thereof, relates to the technical field of paint, and solves the problems that due to the fact that an outer walllatex paint coating layer is easily aged under the effect of an external environment, the overall application effect of the outer wall latex paint is not good. The acrylic acid outer wall latex paintcomprises, by weight, 320-350 parts of water, 2-5 parts of hydroxyethyl cellulose, 8-12 parts of ethylene glycol, 1.2-1.6 parts of polydimethyl siloxane, 90-110 parts of titanium dioxide, 95-115 partsof kaolin, 4-5 parts of wollastonite powder, 260-280 parts of ground calcium carbonate, 170-190 parts of pure acrylic emulsion, 3-5 parts of Tex film-forming agent, 0.8-1 part of PT86 mildew preventive, 0.8-1.2 parts of neutralizer, 4.5-7.5 parts of dispersing agent and 1.2-2.4 parts of pitaya seed extract. The acrylic acid outer wall latex paint has the advantages that the coating layer after the acrylic acid outer wall latex paint is used is good in stability, the coating layer cannot be easily aged under the effect of the external environment, and the overall application effect of the acrylic acid outer wall latex paint is good.

Description

technical field [0001] The invention relates to the technical field of paints and coatings, more specifically, it relates to an acrylic exterior wall latex paint and a preparation process thereof. Background technique [0002] Glue paint is a water-dispersible paint. It is a paint made of synthetic resin emulsion as the base material. After the filler is ground and dispersed, various additives are added. It is also a large class of synthetic resin emulsion paint represented by acrylate copolymer emulsion. . [0003] In the Chinese invention patent whose application publication number is CN108641518A, a kind of exterior wall latex paint is disclosed. In parts by weight, 200-250 parts of acrylic emulsion, 200-220 parts of modified polyurethane emulsion, 80-100 parts of water , 8-12 parts of dispersant, 20-25 parts of propylene glycol, 140-160 parts of mixed filler, 20-40 parts of additive, 20-50 parts of pigment and filler, 8-12 parts of melamine and 15-20 parts of hydroxypro...
