Abstract

The invention discloses elastic exterior wall paint and a production method thereof. The elastic exterior wall paint is prepared from the following components in parts by weight: 2-8 parts of a dispersing agent, 0.5-1.5 parts of a wetting agent, 1-5 parts of a defoaming agent, 0.5-2 parts of a multi-functional agent, 6-12 parts of a film-forming additive, 15-30 parts of ethanediol, 2-7 parts of cellulose, 50-100 parts of kaolin, 130-180 parts of titanium dioxide, 100-200 parts of ground calcium carbonate, 300-500 parts of an elastic emulsion, 1-2 parts of a preservative, 1-3 parts of a thickening agent and 150-300 parts of deionized water. According to the elastic exterior wall paint and the production method thereof, provided by the invention, color fading cannot be easily caused and the stain resistance is good; besides, through component selection and proportioning, the elastic exterior wall paint is enabled to be high in stickiness, good in water-retaining property, stability, construction performance and weather fastness, excellent in adhesion and long in elasticity retention time, and dropping sand is avoided during construction.

Description

technical field [0001] The invention relates to an elastic exterior wall paint and a production method thereof, belonging to the field of chemical materials. Background technique [0002] Elastic paint is made of high elastic synthetic resin emulsion. It is a functional exterior wall paint that prevents micro cracks on the surface of buildings and prevents wall leakage. With high resilience, flexibility and elongation, the tensile strength and extension of the paint can make up for the tiny cracks in the base wall of the building, and it can also be called elastic architectural coatings. The main film-forming substance of elastic exterior wall latex paint is elastic polyacrylic acid synthetic resin emulsion, and its function is to bond other components in the paint into a whole. When the paint is dry and hardened, it can adhere to the surface of the coated substrate to form a uniform, continuous, tough and elastic protective film. The elasticity of the coating film is main...
