Abstract

The invention relates to an environment-friendly coating with visible light catalysis function, and a preparation method thereof, belonging to the field of a coating for building decoration. The environment-friendly coating with visible light catalysis function is prepared by the following active ingredients in parts by weight: 1-20 parts of modified nanocrystalline iron oxide powder with visible light catalysis function, 20-70 parts of silicate, 2-5 parts of gypsum powder, 1-10 parts of titanium dioxide, 0.1-5 parts of powder anticaking agent, 1-10 parts of curing conditioning agent, 1-10 parts of inorganic pigment, and 1-20 parts of filler. The prepared environment-friendly coating with visible light catalysis function not only has the characteristic of strong light absorption capability, but also widens the application range of light catalysis technology, and has higher catalytic activity regardless of ultraviolet light and visible light. In addition, the prepared environment-friendly coating with visible light catalysis function is easily available in raw materials, and low in cost.

Description

technical field [0001] The invention relates to an environmentally friendly coating with photocatalytic function and a preparation method thereof, in particular to an environmentally friendly coating with visible light catalytic function and a preparation method thereof, belonging to the field of coatings for architectural decoration. Background technique [0002] Environment and energy are the major problems that human beings face and need to solve urgently in the 21st century. Photocatalysis has become an ideal environmental pollution control technology and clean energy production due to its unique properties such as deep reaction at room temperature and direct use of solar energy as a light source to drive the reaction. technology. [0003] The photocatalytic method can thoroughly mineralize and remove a variety of organic pollutants, and provides a very good solution for the removal of various organic pollutants and reductive inorganic pollutants, especially toxic and ha...
