Antimicrobial self-cleaning paint and preparation method thereof

Abstract

The invention discloses an antimicrobial self-cleaning paint which contains deionized water, hydroxyethyl cellulose, a pH regulating agent, a dispersing agent, a wetting agent, titanium dioxide powder, an inorganic antimicrobial agent, talcum powder, kaolin, an acrylic emulsion, propylene glycol, alcohol ester-12, a flatting agent, a defoaming agent and hollow microbeads. The invention further discloses a preparation method of the antimicrobial self-cleaning paint. The antimicrobial self-cleaning paint has the strong antibacterial mildewproof property under a wet environment; a paint film can be repeatedly used for killing escherichia coli, staphylococcus aureus, fungi, moss bacteria and phycomycetes for a long time, and can decrease the propagation and the breeding of mucedine and the fungi for a long term. In addition, the antimicrobial self-cleaning paint is excellent in flatting property and constructability, and has the ultra-strong adhesive force. Thus, the paint film is firmed permanently.

Description

technical field [0001] The invention relates to the field of paints, in particular to an antibacterial self-cleaning paint and a preparation method thereof. Background technique [0002] Interior wall paint is a very important decoration material, but due to the lack of sunlight in the room, bacteria and mold are easy to breed in the damp corners of the interior wall paint, and mold spots appear on the interior wall paint coating, which not only loses its decorative and protective functions , but also emit a disgusting musty smell, pollute the indoor environment, induce diseases, seriously threaten people's health and affect people's quality of life. [0003] Since the 1980s, functional coatings such as anti-mildew and anti-bacteria began to appear in foreign countries. However, common anti-mildew and anti-bacterial latex paint products have low inhibitory effect on certain bacteria, and a large amount of anti-mildew and anti-bacterial agents need to be added to achieve the ...

[0002] Interior wall paint is a very important decoration material, but due to the lack of sunlight in the room, bacteria and mold are easy to breed in the damp corners of the interior wall paint, and mold spots appear on the interior wall paint coating, which not only loses its decorative and protective functions , but also emits a disgusting musty smell, pollutes the indoor environment, induces diseases, seriously threatens people's health and affects people's quality of life

[0003] Since the 1980s, functional coatings such as anti-mildew and anti-bacteria began to appear in foreign countries. However, common anti-mildew and anti-bacterial latex paint products have low inhibitory effect on certain bacteria, and a large amount of anti-mildew and anti-bacterial agents need to be added to achieve the desired effect. The effect of this will lead to an increase in the cost of interior wall latex paint and an increase in environmental pollution.

Moreover, the traditional anti-mildew and anti-bacterial latex paint will still appear mildew and moss in the wet weather of the rainy season in some areas.
