Multifunctional composite coating

Abstract

The invention discloses a waterborne multifunctional composite coating, which has disinsection, sterilization and formaldehyde decomposing functions. The composite coating consists of the following components in percentage by weight: 10 percent of polyvinyl alcohol aqueous solution, 15 percent of waterborne epoxy resin, 20 percent of calcium carbonate, 15 percent of anatase nano-titanium oxide, 10 percent of sodium hexametahposphate, 10 percent of pyrethrum, 5 percent of veratrum, 2 percent of isothiazolizone and 13 percent of water, wherein the polyvinyl alcohol aqueous solution contains 20 percent of polyvinyl alcohol. The coating has complete functions, outstanding comprehensive performance and high adaptability, and contributes to improving the environmental quality.

Description

technical field [0001] The invention relates to a multi-functional composite paint, in particular to a water-based multi-functional composite paint for killing insects, sterilizing bacteria and decomposing formaldehyde. Background technique [0002] Mosquitoes and flies are public nuisances of human beings, which dry up people's lives. Existing people generally use spray-type insecticides and heating-evaporative insecticides, which have the advantages of convenience and rapid insecticide, but they are highly toxic and have peculiar smell. Pollution to the environment, the area of ​​anti-killing is small, the time limit is short, the toxic residue is large, and long-term use of a kind of insecticide is easy to produce drug resistance, which needs to be constantly updated; this method of insecticide requires people to frequently carry out insecticide work , which must be done almost every day. With the development of technology, people have invented the method of adding insec...

Problems solved by technology

[0003] During the production process of coatings, bacteria may be introduced into the coating production formula at any stage of the manufacturing process due to contamination of raw materials, unclean equipment or unclean water sources. Once the coating is contaminated with bacteria, it will adhere to the coating surface for production Microorganisms will bring a series of troubles such as loss of gloss and deformation to the coating, and even cause cracking and loss of adhesion of the coating, and more seriously, it will cause corrosion and peeling of the coating, etc.
