Abstract

The invention discloses a catalyst coating and a preparation method thereof. By adding a modified catalyst ZnO into the coating, the mechanism that organic harmful substances are degraded in the presence of the catalyst ZnO is well utilized. By the catalyst coating, the problem of the addition of the harmful substances during the production of the coating is completely solved and the potential safety hazard of the coating is removed; experimental results show that the catalyst ZnO powder and modified ZnO dispersion liquid have excellent formaldehyde purifying, degrading and removing functions, antibacterial and mildew-proof functions and the like, by adding the catalyst ZnO powder and modified ZnO dispersion liquid into the production of the coating and in a form of wall decoration, the catalyst coating is a truly functional novel coating capable of efficiently removing harmful substances such as free formaldehyde and toluene and can take effect for a long term.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a catalytic coating and a preparation method thereof. Background technique [0002] With the continuous development of society and the improvement of people's awareness of environmental protection, the problem of ambient air quality has gradually attracted people's attention. The use of a large number of decoration materials not only improves the visual beauty and luxury, but also causes the continuous deterioration of indoor and outdoor air quality. There are a variety of paint products for purification and removal of harmful substances on the market. The main technology is to add diatomaceous earth, bamboo charcoal and other substances. The removal effect of formaldehyde, benzene, toluene, xylene and other harmful substances is not ideal and lasting, and will cause secondary pollution. [0003] In the paint industry, technicians are also constantly exploring,...
