High-strength antifouling nanometer exterior wall coating

Abstract

The invention discloses exterior wall coating, and in particular relates to high-strength antifouling nanometer exterior wall coating, which is produced for the architectural decoration industry. The high-strength antifouling nanometer exterior wall coating comprises the following components in parts: 1-10 polyvinyl alcohol, 30-50 isobutyl alcohol, 10-20 sodium pyrophosphate, 1-5 high-strength cellulose, 400-500 nano titanium dioxide, 120-150 calcite powder, 100-120 sierozem powder, 300-400 water, 15-35 water glass and 10-30 bentonite. Used as the exterior wall decorative coating, the invention has the advantages of high hardness, washability and long storage period, favorably inhibits propagating growth of mildew and algae, and has better elastic extensibility in order to better adapt to surface layer cracking caused by deformation of a base layer and has a covering function for fine cracks of the base layer; and the high-strength antifouling nanometer exterior wall coating also has the characteristics of better metal texture, over-long outdoor durability and low production cost with respect to an imitation aluminium-plastic plate decorative effect.

Description

technical field [0001] The invention relates to an exterior wall paint, in particular to a high-strength antifouling nanometer exterior wall paint, which is suitable for the exterior wall paint produced in the building decoration industry. Background technique [0002] As we all know, the main purpose of exterior wall paint is to decorate and protect the exterior walls of buildings, so that the appearance of buildings is beautiful and tidy, so as to achieve the purpose of beautifying the urban environment. At the same time, the exterior wall coating can also protect the exterior wall of the building and prolong its service life. In order to obtain ideal decorative and protective effects, exterior wall coatings are required to have rich colors and excellent color retention, and can maintain the original decorative performance for a long time. Because the coating is exposed to the atmosphere, it must withstand wind, sun, and salt spray. Corrosion, rain, cold and heat changes, ...

Problems solved by technology

In order to obtain ideal decorative and protective effects, exterior wall coatings are required to have rich colors and excellent color retention, and can maintain the original decorative performance for a long time. Because the coating is exposed to the atmosphere, it must withstand wind, sun, and salt spray. Corrosion, rain, cold and heat changes, etc. Under the long-term repeated action of these external natural environments, the coating is prone to cracking, powdering, peeling, discoloration, etc
