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 paint with photocatalytic function and a preparation method thereof, in particular to an environmentally friendly paint with visible light catalysis function and a preparation method thereof, and belongs to the field of architectural decoration paints. Background technique [0002] Environment and energy are major issues facing and urgently to be solved in the 21st century. Photocatalysis has become an ideal environmental pollution treatment 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 completely mineralize and remove a variety of organic pollutants, and provides a highly effective method for the removal of various organic pollutants and reducing inorganic pollutants, especially toxic and harmful substances that are diffic...
