Problems solved by technology

At present, many wall paints cannot solve or completely solve these problems, especially the air quality problem. The reason is that the currently used wall paint cannot purify the air or the effect is not good. Not environmentally friendly, not strong in water and alkali resistance, some have no elasticity, poor stain resistance, poor anti-mildew and anti-algae functions, high content of volatile organic compounds (volatile organic compounds)

Abstract

The invention discloses a nanoscale photocatalyst coating, belonging to the technical field of photocatalysts. The nanoscale photocatalyst coating is characterized by comprising the following materials in percentage by weight: 0.7-1.2% of nitrate, 0.6-1.0% of a dispersing agent, 0.1-0.2% of a surfactant, 0.1-0.2% of a pH regulator, 0.3-0.7% of a defoaming agent, 3.5-5.5% of propylene glycol, 2.5-3.0% of dodecanol ester, 16-25% of titanium dioxide, 8-12% of calcined limestone, 3-5% of aluminum sulfate, 35-45% of styrene-acrylic emulsion, 4-5% of nano titanium dioxide, 1-1.2% of a polyurethane thickening agent, 0.3% of a preservative and the balance of distilled water.

Description

technical field [0001] The invention relates to a nanoscale photocatalyst coating, which belongs to the technical field of photocatalyst Background technique [0002] Photocatalyst is a nano-scale metal oxide material (titanium dioxide is more commonly used), which is coated on the surface of the substrate, and under the action of light, it produces a strong catalytic degradation function: it can effectively degrade toxic and harmful gases in the air; it can effectively kill It can kill a variety of bacteria, and can decompose and harmlessly treat the toxins released by bacteria or fungi; it also has functions such as deodorization and antifouling. Under the irradiation of light, the photocatalyst will produce a photocatalytic reaction similar to photosynthesis, produce free hydroxyl groups and active oxygen with strong oxidation ability, have a strong photoredox function, and can oxidize and decompose various organic compounds and parts Inorganic matter, which can destroy...
