Waterborne non-sticky bactericidal coating

Abstract

The invention provides a waterborne non-sticky bactericidal coating. The waterborne non-sticky bactericidal coating is mainly prepared from, by weight, 60-70 parts of polytetrafluoroethylene emulsion, 8-15 parts of acrylic emulsion, 6-8 parts of polymeric aluminum sulfate, 0.4-1 part of a thickener, 1-2 parts of a catalyst, 1-2 parts of photocatalytic titanium dioxide, 1-2 parts of nano silver oxide, 1-2 parts of dimethyl ethanolamine, 0-1.5 parts of pearl powder, 0-6 parts of a high-temperature-resistant toner and 10-15 parts of deionized water. The waterborne non-sticky bactericidal coating is excellent in non-sticking performance, high in sterilization rate and excellent in air purification effect and also has very good yellowing resistance performance. In addition, the waterborne non-sticky bactericidal coating is excellent in comprehensive performance and has good adaptive capacity to a construction environment, the input of temperature and humidity regulation devices is reduced, and the energy consumption of construction is reduced.

Description

technical field [0001] The invention belongs to the field of water-based paints, in particular to a water-based non-stick bactericidal paint. Background technique [0002] Non-stick coating is a special coating whose surface is not easily adhered by other sticky substances or easily removed after adhesion. This kind of coating has extremely low surface energy, small friction coefficient, and is easy to slip. Viscous characteristics, are widely used in household appliances, cooking utensils, automobiles, machinery, chemicals and other industries. Water-based non-stick coatings are most popular with the public and have the largest output because they contain less organic solvents, are safe, and cause less environmental pollution. The research and development of non-stick coatings in my country is still in its infancy. With the progress of society and people's attention to healthy life, people begin to need a multifunctional non-stick coating that is environmentally friendly, ...

AI Technical Summary

Problems solved by technology

[0004] 1. The non-stick performance of traditional water-based non-stick coatings is difficult to meet the increasingly high non-stick requirements;

[0005] 2. Traditional water-based non-stick coatings do not have a strong bactericidal function;

[0006] 3. Light-colored products are prone to yellowing after high temperature;

[0007] 4. Traditional water-based non-stick coatings have strict requirements on construction environment conditions (temperature, humidity), which increases the investment in temperature and humidity control equipment and also increases energy consumption
