Novel nanometer self-cleaning fluorocarbon coating for exterior wall and preparation method thereof

Abstract

The invention discloses a novel nanometer self-cleaning fluorocarbon coating for an exterior wall. The novel nanometer self-cleaning fluorocarbon paint comprises the following components: 220 to 280 parts of deionized water, 8 to 10 parts of dispersing agent 731A, 6 to 8 parts of wetting agent X-405, 3 to 4 parts of neutralizing agent AMP-95, 3 to 4 parts of preservative LEX, 500 parts of water-based fluorous emulsion, 160 to 200 parts of titanium dioxide R706, 20 to 25 parts of ethanol, 30 to 40 parts of nanometer TiO2, 20 to 30 parts of nanometer ZnO, 20 to 25 parts of hydroxyethyl cellulose, 25 to 40 parts of propylene glycol, 6 to 8 parts of antifoaming agent NXZ, 1 part of acrylic associative thickener TT935, and 2 to 4 parts of flatting agent RM-2020. After the nanometer material with photocatalytic function is added to the coating, the surface of the coating is hydrophilic under the ultraviolet irradiation, and the micronization is brought at the same time, therefore hydrophilic and oleophilic substances attached to the film surface can be effectively cleaned and degraded, and as a result, good self-cleaning effect can be achieved.

Description

technical field [0001] The invention relates to a coating for exterior walls, in particular to a novel nanometer self-cleaning fluorocarbon exterior wall coating and a preparation method thereof. Background technique [0002] Exterior wall coatings are rich in color, flexible and diverse in finishes, can express a variety of architectural styles, simple in construction, easy to maintain and update, light in weight, safe and reliable, and are becoming the leading exterior wall finishing materials in my country. Exterior wall finish material. my country is currently at the peak of urbanization construction, and high-quality exterior wall coatings have broad demand space and development potential. The implementation of housing industrialization and building energy conservation has also played a huge role in promoting the promotion and application of exterior wall coatings. [0003] Insufficient stain resistance of coatings is a common problem in exterior wall coati...
