Problems solved by technology

In the process of decoration, people usually choose paints with antibacterial effects. During the use of existing paints, especially wall paints, mildew spots often appear on the wall after use. It takes a little longer and it is easy to appear. Large pieces of paint fall off, and usually contain a certain amount of formaldehyde or volatile organic substances

Embodiment 1

[0013] An antibacterial coating, which is composed of the following components by weight: 15 parts of acrylic resin emulsion, 10 parts of titanium dioxide, 3 parts of silicon micropowder, 4 parts of quartz sand, 0.7 parts of cellulose acetate, 3 parts of talc, 0.3 parts of oxalic acid part, 0.5 part of dispersant, 0.3 part of defoamer, 0.6 part of antibacterial agent, and 12 parts of water.

[0014] Wherein, the antibacterial agent is formed by mixing a natural antibacterial agent and an inorganic antibacterial agent in a weight ratio of 5:2. The natural antibacterial agent is composed of natural polymer chitosan, mustard, castor oil, and allicin, and the weight ratio of each component is natural polymer chitosan: mustard: castor oil: allicin=3:0.5:1:2. The inorganic antibacterial agent is a mixture composed of nano titanium dioxide and nano zinc oxide, and the weight ratio of the nano titanium dioxide and nano zinc oxide is 1:0.5.

Embodiment 2

[0016] An antibacterial coating, which is composed of the following components in parts by weight: 10 parts of acrylic resin emulsion, 15 parts of titanium dioxide, 1 part of silicon micropowder, 5 parts of quartz sand, 0.5 parts of cellulose acetate, 5 parts of talcum powder, and 0.1 parts of oxalic acid part, 0.8 part of dispersant, 0.1 part of defoamer, 0.8 part of antibacterial agent, and 5 parts of water. Wherein, the prescription of antibacterial agent is identical with embodiment 1.

Embodiment 3

[0018] An antibacterial coating, consisting of the following components in parts by weight: 18 parts of acrylic resin emulsion, 6 parts of titanium dioxide, 4 parts of silicon micropowder, 3 parts of quartz sand, 0.8 parts of cellulose acetate, 2 parts of talc, 0.4 parts of oxalic acid part, 0.3 part of dispersant, 0.4 part of defoamer, 0.5 part of antibacterial agent, and 16 parts of water. Wherein, the prescription of antibacterial agent is identical with embodiment 1.

[0019] Control 1

[0020] Its formula is identical with embodiment 1 formula, and difference is that the composition of antibacterial agent is different, and antibacterial agent only uses natural antibacterial agent, and natural antibacterial agent is made up of natural polymer chitosan, mustard, castor oil, allicin, and the weight ratio of each composition It is a natural polymer chitosan: mustard: castor oil: allicin=3:0.5:1:2.

Abstract

The invention discloses an anti-bacteria coating. The anti-bacteria coating is composed of, by weight, the following components of 10-20 parts of acrylic resin emulsion, 5-15 parts of titanium dioxide, 1-5 parts of silica powder, 1-5 parts of quartz sand, 0.5-1 part of cellulose acetate, 1-5 parts of talcum powder, 0.1-0.5 part of oxalic acid, 0.1-0.8 part of dispersing agent, 0.1-0.5 part of defoaming agent, 0.4-0.8 part of antibacterial agent and 5-20 parts of water. According to the anti-bacteria coating, the composition is reasonable, the cost is low, the compatibility among all the components is good, environment protection and bacteria inhibition are achieved, mildew can be effectively inhibited from being generated, the antibacterial effect is long lasting, and the antibacterial agent is green and environment-friendly so that pollution to the environment cannot be caused. A natural antibacterial agent and an inorganic antibacterial agent are mixedly used, and therefore the problem that the stabilization is poor if only the natural antibacterial agent is used, the pollution brought by only using an organic antibacterial agent and the problem that the cost is high if only the inorganic bacterial agent is used are avoided; the antimould effect is more lasting through the combination usage.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an antibacterial coating. Background technique [0002] With the development of society and the improvement of people's living standards, people attach great importance to their own health, quality of life and living environment. With the rapid development of industry, the living environment of human beings has further deteriorated, and harmful microorganisms such as bacteria and molds have seriously endangered human health. In the process of decoration, people usually choose paints with antibacterial effects. During the use of existing paints, especially wall paints, mildew spots often appear on the wall after use. It takes a little longer and it is easy to appear. Large pieces of paint fall off, and usually contain a certain amount of formaldehyde or volatile organic substances harmful to human health, which seriously endanger human health; in addition, the existi...
