Abstract

The invention relates to a preparation method of photocatalyst paint and belongs to the technical field of photocatalysts. The photocatalyst paint comprises following raw materials by weight: 20-32 parts of deionized water, 1-2.0 parts of an antifreezing agent, 0.15-0.25 part of glycerin, 0.55-0.7 part of liquid paraffin, 0.2 part of an antiseptic, 0.1-0.2 part of a pH conditioning agent, 1 part of nanometer titanium dioxide, 2-2.5 parts of an anion generation material, 20-25 parts of nanometer titanium dioxide powder, 12-15 parts of calcium carbonate, 1-2 parts of n-dodecanol ester, 25-45 parts of acrylic acid emulsion and 1-2 parts of a thickening agent.

Description

technical field [0001] The invention relates to a preparation method of a photocatalyst coating, which belongs to the technical field of photocatalyst. 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 fragrances such as air fresheners. This method cannot really remove harmful substances in the air. Photocatalyst is a nano-scale metal oxide material (titanium dioxide is more commonly used), which is coated...
