Abstract

A composite photocatalyst air-purifying water-based interior wall paint and a preparation method thereof. Its raw material composition is as follows according to weight percentage: photocatalytic filler 5.5-22.3%; polyurethane emulsion 25-65%; propylene glycol phenyl ether 1-6%; Dispersant 2~6%; stabilizer 2~4%; wetting agent 1~2%; water 20~60%; antifungal agent 1.5~4%; defoamer 1~2%; leveling agent 0.5~2% %; Thickener 0.5-1%; Photocatalytic filler is composed of nano-anatase titanium dioxide in a weight ratio of 5-9:1-5 combined with nano-zinc oxide or nano-tin dioxide. The coating has good air purification ability, and can effectively degrade harmful gases in the air and kill bacteria and viruses under the excitation of ultraviolet rays. As an interior wall decoration material, the paint has good hiding power, adhesion and excellent stability. The invention has a simple production process, is applicable to various coating methods, and is easy to popularize and apply.

Description

technical field [0001] The invention relates to a photocatalyst coating and a preparation method of the coating. Background technique [0002] With the development of social economy and the improvement of living standards, people put forward higher requirements for working and living conditions. The use of a large number of new building materials and decorative materials has created a stylish, beautiful, convenient and comfortable living space for modern people. In the past two decades, due to changes in life and work patterns, modern people spend more and more time indoors. Many people spend almost 90% of their time indoors. As a result, a large number of "sick buildings" are caused by a variety of harmful chemical components contained in new materials, and the number of people suffering from "building disease syndrome", "building complications" and "multiple chemical allergies" continues to increase. People find that due to the widespread use of new building materials, e...
