Abstract

The invention provides a photocatalytic air fresh coating and a preparation method thereof, and belongs to the field of indoor coating material, in particular to a coating for purifying air through a photocatalytic material and an anion generating material. The coating comprises the following raw materials in weight portion: 20 to 32 portions of deionized water, 1 to 2.0 portions of antifreeze agent, 0.1 to 0.2 portion of wetting agent, 0.5 to 0.6 portion of dispersing agent, 0.2 portion of preservative, 0.1 to 0.2 portion of pH regulator, 1 portion of nano titanium dioxide, 2 to 2.5 portions of the anion generating material, 20 to 25 portions of rutile titanium dioxide powder, 2 to 2.5 portions of diatomite, 12 to 15 portions of coarse whiting, 1 to 2 portions of film forming auxiliary, 25 to 45 portions of acrylic acid latex and 1 to 2 portions of thickening agent. The coating can keep the indoor air fresh for a long time and reach the first class indoor air environment standard of the nation. The anion releasing quantity of the coating reaches 2,626/cm<3> and the antibacterium and bacteriostasis ratio of the coating reaches more than 97 percent.

Description

technical field [0001] The invention relates to a photocatalyst air freshening paint and a preparation method thereof, which belong to the field of indoor paint materials, in particular to a paint with dual functions for purifying air by compounding photocatalyst materials and negative ion generating materials and combining them with high-performance paints. Background technique [0002] With the rapid development of the national economy, people's requirements for interior decoration are also increasing. The concept of environmental protection has been deeply rooted in the hearts of the people, and the improvement of the home environment is imminent. Harmful gases such as formaldehyde, ammonia, and benzene released from furniture and decoration materials (plates, oil paints, viscose, etc.), as well as various molds, viruses, and odors in the room have seriously endangered people's health and living environment. In the prior art, the original smell is generally covered by fr...
