Composite photocatalysis coating

Abstract

The invention discloses a composite photocatalysis coating containing substrate material, nano titanium dioxide, nano diatom ooze, a bamboo charcoal extract, a coalescent, a dispersant, water and the like. The composite photocatalysis coating has strong adhesive force to wall surfaces, can actively, rapidly and omnidirectionally purify air for a long term and effectively restrain harmful microorganisms, is convenient to construct and can be widely applied to the outer surfaces of objects such as buildings, transportation vehicles, cabinets and the like.

Description

technical field [0001] The invention relates to a paint, in particular to a composite photocatalyst paint. Background technique [0002] Studies have proved that many home decoration materials will slowly release small molecule harmful substances such as aldehydes, phenols, alcohols, etc., which are likely to cause damage to human health. In addition, with the increasing industrialization and urbanization of human society, urban air pollution is becoming more and more serious. For example, a large amount of harmful gases such as sulfur dioxide, carbon monoxide, and low-valence nitrogen compounds emitted by industrial coal combustion and automobile exhaust make the air pollution in people's living environment more and more serious. In addition, it has been confirmed by investigation and research that indoor microbial pollution is one of the main causes of various poisonings, infections, allergic diseases and infectious diseases. It can be seen that research and development ...
