Preparation and application method of optical catalysed environment protection type coating

Abstract

The invention provides a preparation and application method for photocatalysis environmental protection type painting, which relates to construction painting, especially provides a preparation and application method for photocatalysis function painting, which includes steps: mixing titanium-containing organic, water, chelating agent and hydrolysis inhibitor to prepare nano anatase type titanium dioxide water sol; adding metal, oxide or impure titanium dioxide photocatalyst into the titanium dioxide water sol and stirring equably. Using method is coating inorganic isolated layer firstly and coating the photocatalysis painting after drying. Advantages of the invention are: the prepared painting and using technique can be widely used for inner and outer wall surface of building and is harmless to bottom ainting, photocatalysis efficiency is high, cost is low, bonding is firm, transparency is good, preparation is simple, and usage is easy.

Description

technical field [0001] The invention relates to architectural coatings, in particular to methods for preparing and using coatings with photocatalytic functions. Background technique [0002] Air pollution includes outdoor air pollution and indoor air pollution, especially formaldehyde and benzene series in indoor air are much more harmful to human health than outdoor, such as formaldehyde and benzene series are recognized in the world Potential carcinogens and strong carcinogens, together with other volatile organic compounds, can cause diseases of the respiratory system, blood system and nervous system, and can also cause fetal malformation, which needs to be resolved urgently. Air pollution has many sources and great harm, especially volatile organic gases, which are not only of various types, but also difficult to control, and there is no convenient, effective and practical treatment method. Since titanium dioxide semiconductor photocatalyst can...
