Antibacterial composite coating

Abstract

The invention discloses an antibacterial flame resistant composite coating and relates to the technical field of chemical industry. The coating comprises the components in parts by weight: 20-25 parts of colophony resins, 45-50 parts of butyl emulsion, 5-8 parts of a nanometer oxide granule reinforcing agent, 13-15 parts of an aliphat curing agent, 7-9 parts of sodium sulphate, 3-5 parts of talcum powder, 2-4 parts of carbon black, 1-6 parts of a thickening agent , 8-9 parts of nanometer silicon dioxide, 4-6 parts of nanometer zinc oxide, 1-3 parts of a nanometer double hydrophobic agent, 7-9 parts of a nanometer reinforcing agent, 1-2 parts of a nanometer anti-ager, 4-6 parts of nanometer silver powder and 5-8 parts of polyester acrylate. According to the antibacterial flame-resistant composite coating disclosed by the invention, a formula is provided, so that the composite coating has favorable bacteria resisting and bacteria killing characteristics, and can voluntarily kill bacteria and pathogenic bacteria, adhered on the coating. Through the adoption of the coating, the water resistance, the adhesive force and the chemical performance are stable, and besides, under the circumstance that the coating is heated, the fire resistance performance of a flame resistant system is not influenced; from the view of the using effect, the coating is good in ductility, high in stretching strength and good in color protecting performance.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an antibacterial and flame-retardant composite coating. Background technique [0002] With the development and progress of society and the improvement of material living standards, people have begun to consider the comfort and environmental protection of decorative materials, especially exterior wall latex paint, in the selection of building decoration materials for the reconstruction of residential buildings and other buildings and decoration. Multifunctional requirements are one of the important conditions for material selection. As an important product category in home decoration materials, coatings for building wall decoration directly reflect and affect the effect and function of home decoration. In recent years, the market demand for this type of products tends to be multi-functional, high added value and high-grade. Therefore, according to the different function...

Problems solved by technology

However, in modern life, there are bacteria in various environments, especially with the aggravation of pollution in modern society, various bacteria and germs are easy to breed and multiply, especially for various household appliances and electronic products that the human body often contacts. For example, cameras, mobile phones, etc., and UV coatings have no antibacterial and bactericidal functions. During storage and use, the surface of cameras, mobile phones and other products will carry a certain amount of bacteria. In order to prevent these bacteria and germs from infecting the human body, people use The paint layer puts forward higher requirements, so that the paint layer has antibacterial and bactericidal properties, and the bacteria and germs attached to the paint layer can be killed by itself through the antibacterial properties of the paint layer itself.
