Problems solved by technology

The coating mainly degrades harmful gases through nano-titanium dioxide. Its defect is that nano-titanium dioxide needs to be irradiated by ultraviolet rays of sunlight to produce photocatalysis, and it is difficult to function in rainy weather, so the actual degradation effect is not good. Cleanliness, mildew resistance, sterilization, etc. are also not ideal

Abstract

The invention provides a water-based coating with self-cleaning, anti-mildew, sterilization and air purification functions. The water-based coating is prepared from following components in parts by weight: 20-30 parts of organic silicon resin, 20-30 parts of a water-based fluorocarbon emulsion, 0.4-0.9 parts of a coalescing agent, 30-35 parts of water, 0.5-1 part of a dispersing agent, 0.1-0.6 parts of an antifoaming agent, 1-1.5 parts of a leveling agent, 10-15 parts of pigments, 8-14 parts of filler and 7-8 parts of an anti-mildew sterilizing agent. The water-based coating has better self-cleaning, anti-mildew, sterilization and air purification functions.

Description

Technical field: [0001] The invention relates to a water-based paint, in particular to a water-based paint with functions of self-cleaning, mildew resistance, sterilization and air purification. Background technique: [0002] Since the reform and opening up, with the rapid growth of China's national economy and the continuous improvement of people's living standards, the production and consumption of coatings are growing at a rapid rate. At present, China has become the second largest consumer of coatings in the world, and its annual output has reached about 600 tons. However, compared with developed countries, the consumption structure of coatings in my country is still not reasonable, and high-pollution coatings still occupy a large proportion, causing serious harm to the environment and construction personnel. With the change of global climate and the increasing tension of resources and energy, countries around the world have successively formulated strict environmental ...
