[0003] At present, the anti-mold and preservatives commonly used in coatings have only a single function. During the production of coatings, anti-mold and preservatives must be added separately. None of them has the effect of decomposing organic poisons in the air, and some preservatives also contain formaldehyde, which is harmful to the human body.
At present, there is no special additive for coatings to decompose organic poisons in the air

Abstract
The invention relates to a nanometer multifunctional coating additive, which is characterized in that it is composed of nanometer titanium dioxide, nanometer zinc oxide, silver-loaded nanometer zirconium phosphate, N-(2-benzimidazole)-carbamate, auxiliary materials and water . Due to the nano-titanium dioxide and nano-zinc oxide contained in the composition generate free oxygen under the action of photocatalysis, which plays the role of sterilization, anti-mildew and anti-corrosion, and can decompose toxic organic substances in the air at the same time. Silver-loaded nano-zirconium phosphate has antibacterial effect, N-( 2-benzimidazole)-carbamate has mildew-proof effect; Thereby the present invention has the effects such as mildew-proof, anticorrosion, sterilization, decomposition organic poison, can be used for latex paint, water-emulsion type interior and exterior wall paint, water-based adhesive, Water-based pigment paste, etc. When the dosage of the present invention is 0.1% to 0.3% of the paint, the anti-mildew efficiency of the paint reaches 99%, the bactericidal efficiency reaches 99.5%, the indoor formaldehyde removal rate reaches more than 80%, and the odor substance dimethyl sulfide removal rate reaches 90%. above.
Description
technical field [0001] The invention relates to a paint additive, in particular to a paint water-based anti-mildew, anti-corrosion, bactericide and organic poison decomposing agent in the air. Background technique [0002] In the production process of water-based paints, antifungal agents and preservatives need to be added to kill molds, inhibit the growth of bacteria, molds, and yeasts, and prevent the paints from becoming moldy, smelly, discolored, and decreasing in viscosity. [0003] The anti-mildew and preservatives commonly used in coatings have only a single function. During the production of coatings, anti-mildew and anti-corrosion agents must be added separately. None of them has the effect of decomposing organic poisons in the air, and some preservatives also contain formaldehyde, which is harmful to the human body. At present, there is no special additive for coatings to decompose organic poisons in the air. Contents of the invention [0004] The object of the ...
