Abstract

The invention provides an inorganic nano coating. The coating is characterized in that the coating consists of the following components by weight percentage: 1 to 10 percent of CH3CH2OH, 0.1 to 10 percent of nano TiO2, 1 to 10 percent of TiO2, 0.1 to 10 percent of nano ZnO, 10 to 30 percent of Mg(OH)2, 12 to 50 percent of filler, 1 to 20 percent of base material, 0.5 to 40 percent of auxiliary agent, and the balance being water. The invention also provides a method for preparing the coating. The method comprises: the nano TiO2 and the nano ZnO are dispersed in the CH3CH2OH to prepare nano pulp, the nano pulp is added with the mixture of water, the TiO2, the Mg(OH)2, the filler, the base material and the auxiliary agent, and dispersed and stirred to obtain the finished product. The coating has the functions of light purification, sterilization and removal of foreign flavor indoors.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular, the invention relates to an inorganic nano coating and a preparation method thereof. Background technique [0002] Most synthetic coatings generally contain a large amount of organic solvents and certain toxic pigments, fillers and molecular additives, which produce "three wastes" during production and use, pollute the environment and affect human health. [0003] The pollution of paint to the atmosphere mainly refers to the discharge of volatile substances generated during the production or use of paint into the atmosphere, causing pollution. In addition to the film-forming matrix, the chemical substances in the paint, such as solvents, plasticizers, additives, etc., are mostly volatile organic compounds with certain toxicity. These substances are the main source of paint pollution to the atmosphere. one of the main sources of pollution. In particular, organic solven...
