Super-weatherability anti-acid rain raindrop imprint-resistant external wall water paint and preparation method thereof

Abstract

The invention discloses super-weatherability anti-acid rain raindrop imprint-resistant external wall water paint and a preparation method thereof. The super-weatherability anti-acid rain raindrop imprint-resistant external wall water paint comprises deionized water, a thickener A, a wetting agent A, a wetting agent B, a dispersant, a defoamer, a film forming aid, a pH stabilizer, an antifreezing agent, titanium dioxide, barite, mica powder, calcined kaolin, a modified polymer emulsion, a thickener B, a leveling agent, a bactericidal mildew preventive and deionized water according to mass percents. The super-weatherability anti-acid rain raindrop imprint-resistant external wall water paint has acid and alkali resistance, weatherability, water resistance, mildew proof effects, raindrop imprint resistance, scrubbing resistance, environmental friendliness and energy saving.

Description

technical field [0001] The invention relates to a coating for exterior walls of buildings, in particular to a super-weather-resistant, acid-rain-proof, and rain-mark-resistant exterior wall water-based paint and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy, the technology of building exterior wall facing materials has also been increasingly improved and optimized. After years of hard work, the production technology of acrylic latex coatings has matured and has been widely used in low and medium buildings, which can basically meet the requirements of 5-10 years. With the development of the economy, buildings in many large and medium cities are moving towards With the development of large-scale, large-scale and high-rise development, the performance requirements of coatings are gradually improved. In addition to the relatively harsh environmental conditions such as "acid rain, damp heat, static ...

Problems solved by technology

After years of hard work, the production technology of acrylic latex coatings has matured and has been widely used in low and medium buildings, which can basically meet the requirements of 5-10 years. With the development of the economy, buildings in many large and medium cities are moving towards With the development of large-scale, large-scale and high-rise development, the performance requirements of coatings are gradually improved. In addition to the relatively harsh environmental conditions such as "acid rain, damp heat, static wind, dust, and mold" in China, the existing acrylic coatings have high temperature and are easy to return. Sticky, easy to be brittle at low temperature, easy to be corroded by acid rain, poor stain resistance, rain stain pollution and other defects, resulting in the application and promotion of existing architectural coatings, which have been restricted and affected to a certain extent.
