Elastic antifouling aqueous fluorocarbon exterior wall paint

Abstract

The invention provides an elastic antifouling aqueous fluorocarbon exterior wall paint. The paint comprises the following components, by weight, 16-20 parts of water, 15-27 parts of a self-crosslinking elastic acrylic emulsion, 12-22 parts of an aqueous fluorocarbon emulsion, 15-20 parts of titanium dioxide, 12-18 parts of barium sulfate, 4-8 parts of calcined kaolin and 1-1.4 parts of a film forming agent. In the invention, the self-crosslinking elastic acrylic emulsion is treated as a main base material to reach an anti-crack requirement, and the aqueous fluorocarbon emulsion having a good compatibility is matched for modifying to make a paint film having low surface free energy and a good lipophobic property in order to make the formed film compact, so the paint film cannot be polluted by blots, and can be easily cleaned after the blot pollution; and rutile and titanium dioxide are simultaneously combined to improve the weather ability, the chemicals (acid rain, salts and the like) corrosion resistance of the film, so the film has good color and light maintenance properties, thereby the elastic antifouling aqueous fluorocarbon exterior wall paint is a new high-performance elastic antifouling aqueous fluorocarbon exterior wall paint.

Description

technical field [0001] The invention relates to an exterior wall latex paint. Background technique [0002] Exterior wall latex paint is already a mature technology. Because of its low cost, easy construction, and environmental protection, it has become a commonly used material in the decoration and protection of exterior walls of buildings. With the popularity of exterior wall latex paint, there are still some problems to be solved in the application of high performance requirements: cracks appear soon after construction, the wall is easily polluted by some air pollutants and cannot be cleaned, and the environment is relatively harsh. (such as acid rain, seaside with high salt content), the color and gloss of the coating film fade quickly. Contents of the invention [0003] The purpose of the present invention is to provide a water-based fluorocarbon elastic antifouling exterior wall paint to overcome the above-mentioned defects in the prior art. [0004] The water-base...
