Abstract

The invention relates to a nano water-based fluorocarbon insulated elastic exterior wall paint which is characterized by comprising the following components: nano ATO powder, titanium dioxide, calcined kaolin, calcium carbonate, a nano zirconia dispersion liquid, cellulose, a self-crosslinking elastic emulsion, a fluorocarbon emulsion, a covering emulsion, hollow glass microbeads, auxiliary agents, and the balance being water. The paint has the advantages that a paint film has lower surface free energy and is endowed with a good oleophobicity; a paint film formed by adding the self-crosslinking emulsion is more dense so as to make the paint film less susceptible to contaminate by stains, and simultaneously is more easily washed cleanly after being contaminated by the stains; and finally, in cooperation with a proper amount of the hollow glass microbeads, the nano zirconia dispersion liquid, the nano ATO powder and other functional additives, the insulation, anti-cracking and antifouling requirements of people on exterior walls are satisfied, the paint film is not damaged after the stains are washed cleanly, and thus the novel high-performance weather-proof exterior wall emulsion paint is provided for exterior wall decoration.

Description

technical field [0001] The invention uses silicon-containing water-based fluorocarbon emulsion and self-crosslinking elastic acrylic emulsion as base materials, and is equipped with functional additives such as hollow microspheres, nano-zirconium dioxide, nano-tin antimony oxide, etc. Dirty 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. As far as exterior wall heat insulation coatings are concerned, there are still some problems to be solved and higher requirements in practical applications: heat insulation coatings are easy to crack, have no elasticity, poor stain resistance, poor weather resistance, and high cost, etc. . Therefore urgently need to develop new exterior wall latex paint that overcomes the shortcoming of present ext...
