Abstract

The invention relates to a high-pollution-resistance matte external-wall elastic paint comprises the following components in parts by weight: 13-26 parts of water, 0.4-0.8 part of hydroxyethyl cellulose, 0.1-0.2 part of pH regulator, 1-2 parts of ethylene glycol, 0.3-0.5 part of water-based wetting agent, 0.8-1.5 parts of hydrophobic modified dispersing agent, 15-16 parts of titanium dioxide, 5-7 parts of coarse whiting, 10-12 parts of calcined kaolin, 4-6 parts of diatomite, 30-40 parts of pure acrylic elastic emulsion, 1.5-2.5 parts of water-based defoaming agent, 1-2 parts of alcohol ester-12, 0.1-0.3 part of anti-pollution paint aid, 0.3-0.5 part of sulfonic acid aid and 0.1-0.2 part of wetting and antifreezing agent. The high-pollution-resistance matte external-wall elastic paint overcomes the defect that the existing elastic paint can not have high elasticity and pollution resistance at the same time and can not cover the roughness of the wall surface due to high glossiness, has the advantages of high elasticity and pollution resistance, and can modify the surface roughness of the wall.

Description

technical field [0001] The invention relates to a highly stain-resistant matte exterior wall elastic paint and a preparation method thereof, which are applied in the field of architectural decoration. Background technique [0002] At present, among the coatings used for building exterior walls, elastic coatings maintain high elasticity, strength and elongation within a certain temperature range. When they are coated on the surface of the base layer, the coating film will not break when the base wall is cracked, and has a relatively high performance. Good anti-crack and anti-leakage properties can effectively protect the wall from further damage. Therefore choose elastic coating as exterior wall paint and just more and more be subjected to people's favor. However, the glossiness of conventional elastic coatings is high, so that in the process of exterior wall construction, if the flatness of the wall surface is poor, the high glossiness will lead to obvious unevenness of the...
