Abstract

The invention relates to the technical field of coatings, and discloses acid-rain-resistant elastic texture paint, which comprises the following components by mass: 10.0-20.0% of water, 0.6%-1.0% of an ammonium salt dispersant, 0.1%-0.2% of a wetting agent, 0.5%-1.0% of a defoaming agent, 1.0%-1.5% of propylene glycol, 0.1%-0.2% of a pH regulator, 0.2%-0.4% of a bactericide, 0.3%-0.5% of bentonite, 10.0%-15.0% of rutile type titanium dioxide powder, 35%-45% of precipitated barium sulfate, 0%-0.5% of a coalescing agent, 35.0%-40.0% of an elastic emulsion, and 0.4%-1.0% of a thickening agent. The paint is applied to outdoor building walls, overcomes the defect of poor acid rain resistance of the existing elastic texture paint for the outer walls, has high elastic covering power performance and excellent acid rain resistance, and avoids damage to the outer walls of buildings caused by acid rain, cracking of the outer walls and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an acid rain-resistant elastic brushed paint and a preparation method thereof, which are suitable for acid rain areas and used for protection and decoration of building exterior wall surfaces. Background technique [0002] The formation of acid rain is mainly caused by man-made discharge of a large amount of acidic substances into the atmosphere. The acid rain in my country is mainly formed by burning coal with high sulfur content. In addition, exhaust gas emitted by various motor vehicles is also an important reason for the formation of acid rain. A large amount of environmental monitoring data shows that due to the increase of acidic substances in the atmosphere, the cloud water over most parts of the earth is becoming acidic. If it is not controlled, the area of ​​acid rain will continue to expand, and the harm to humans will also increase day by day. [0003] Sulfur dioxide...
