Abstract

The invention provides a nano titanium dioxide-doped water-based paint with a sterilization function and a production process thereof. The water-based paint is prepared from the following raw materials in percentage by weight: 20-32% of water-based acrylate emulsion, 1-3% of iron-doped nano titanium dioxide, 0.5-1.5% of cerium-doped nano titanium dioxide, 2-5% of silver-loaded tourmaline powder, 6-12% of rectorite micro powder, 0.5-0.8% of aluminum citrate, 0.2-0.5% of silane coupling agent, 6-10% of alcohol solvent and the balance of water. The coating produced by the method is smooth in appearance, high in adhesive force and high in strength, and has excellent air purification performance and antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based coating with bactericidal function doped with nano-titanium dioxide and a production process. Background technique [0002] With the development of science and technology, the improvement of living standards and the use of various chemical and chemical products, some air pollution will occur in some places in people's lives. Air pollution is mainly caused by dust, bacteria, and poisonous gases. Especially in some closed environments, such as bathrooms, cars, bedrooms, etc., the air quality is worse. Tests have proved that the odor in life is mainly caused by the metabolism of humans or animals, as well as smoke, insecticides, cleaning agents, sewage, feces, industrial gases, oil washing, adhesives, etc. Distributed various substances such as: ammonia, formaldehyde, hydrogen sulfide, methyl mercaptan and other components. [0003] With the introduction of various...
