Abstract

The invention discloses formaldehyde-removal nano-photocatalyst paint and belongs to the technical field of paint. The paint is prepared from raw materials in parts by weight as follows: 55-60 parts of a fluorocarbon emulsion, 13-15 parts of nano-titania, 7-9 parts of modified silicon dioxide, 3-7 parts of modified magnesium hydroxide, 1-2 parts of dodecanol, 4-6 parts of zinc borate, 5-7 parts of diammonium hydrogen phosphate, 1-3 parts of plant essential oil, 0.5-1.5 parts of a preservative, 0.1-0.8 parts of a leveling agent, 0.1-0.5 parts of an ultraviolet absorbent, 2-6 parts of a dispersant, 1-2 parts of a defoaming agent, 1-2 parts of a thickening agent, 5-10 parts of glycol and a proper amount of water. The invention further discloses a preparation method of the formaldehyde-removal nano-photocatalyst paint. The paint is environment-friendly, pollution-free, high in intensity, corrosion-resistant, waterproof, flame-retardant and high-temperature-resistant and has excellent formaldehyde removal capacity.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nano-photocatalyst formaldehyde-removing coating and a preparation method thereof. Background technique [0002] Nano-photocatalyst refers to a substance that does not undergo chemical changes itself under light, but can promote chemical reactions. Its function is like chlorophyll in photosynthesis. Anatase nano-TiO2 is the most important photocatalyst material. When it absorbs energy from sunlight or other light sources, the electrons on the surface of the particles are activated and escape from their original orbits, while positively charged holes are generated on the surface. The escaping electrons have strong reducing properties, while the holes have strong oxidizing properties. After the two react with the moisture in the air, active oxygen and hydroxyl radicals will be generated. Active oxygen and hydroxyl radicals can oxidize and decompose most organic matter, pollutan...
