Abstract

The invention relates to the field of building materials and particularly relates to wall paint and a preparation method thereof. The wall paint comprises the following raw material components in parts by mass: 15-25 parts of deionized water, 3-5 parts of pigment dispersing agent, 1-3 parts of bactericide, 2-6 parts of PH regulator, 4-9 parts of defoaming agent, 10-20 parts of pigment, 20-35 parts of inorganic filler, 15-25 parts of air purifying emulsion, 4-10 parts of nanometer titanium dioxide / diatomite composite material and 2-4 parts of thickening agent. Compared with the wall paint in the prior art, the wall paint provided by the invention has the advantages that nanometer titanium dioxide / diatomite composite material is used as a photocatalyst material added into a coating, so that the problem that nanometer titanium dioxide is easily conglobated is solved, the nanometer performance of nanometer titanium dioxide can not be lost, and furthermore, the capability of nanometer titanium dioxide for absorbing toxic and harmful substances is enhanced.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a wall paint and a preparation method thereof. Background technique [0002] In recent years, with the advancement of science and technology and the rapid development of modern industry, environmental problems have become increasingly serious, and human beings have paid more attention to health. With the gradual improvement of environmental protection awareness, consumers have higher and higher requirements for the environmental protection of coatings. [0003] The traditional coatings produced by most traditional coatings companies are far from meeting the requirements of consumers, because the nano-silica photocatalyst products added in traditional coatings are prone to agglomeration, resulting in loss of nano-performance and affecting their ability to absorb toxic and harmful substances. . Contents of the invention [0004] The object of the present invention is to provide...
