Nano-antimicrobial fungus-resisting paint

Abstract

The invention discloses nanometer antibacterial mildewproof coating. The invention comprises the following components according to the weight percentage of The invention of water-based coating, 3 to 7 percent of nanometer silver, 3 to 7 percent of nanometer copper or nanometer zinc occupies, and 4 to 11 percent of nanometer zinc oxide or nanometer titanium dioxide. The application of the nanometer antibacterial mildewproof coating is as follows: the nanometer antibacterial mildewproof coating is evenly painted on the medical instruments, the medical furniture and the indoor wall bodies of a hospital, such as hospital beds, bedside cabinets, hospital carts, office tables and chairs of a hospital, so as to ensure the surfaces of the articles to be covered through the coating, when harmful microorganisms in air or at the parts of human hands are contacted with the articles, the harmful microorganisms left on the articles are captured and killed through the metallic ions with positive charge in the nanometer antibacterial mildewproof coating, and therefore the invention prevents the cross spreading of the harmful microorganisms in the hospital.

Description

Nano antibacterial and anti-mildew coating 【Technical field】 The invention relates to a nanometer antibacterial and mildew-proof coating and its application, which belongs to the paint category of chemical products. 【Background technique】 There are two main types of antibacterial and antifungal coatings: The first category is to add organic antibacterial agents or organic antifungal agents to the paint, which can kill bacteria or mold attached to the surface of the coated article. The disadvantage is that the action time is short. With the self-decomposition of organic matter, the antibacterial or anti-mildew effect will gradually disappear, harmful microorganisms will form drug resistance, and some organic matter will have negative effects on the human body and the environment. The second category is to use inorganic materials as antibacterial or antifungal agents. Inorganic series of antibacterial or antifungal agents are divided into two types: one is made of silver...

AI Technical Summary

Problems solved by technology

The coating made of the former inorganic material has good antibacterial or antimildew effect, and is non-toxic and harmless. The disadvantage is that metal ions such as silver, copper, and zinc will be lost, and the antibacterial or antimildew effect will gradually decrease, and It is difficult to achieve both antibacterial and anti-mildew; the latter uses nano-metal oxides to make coatings, which have good anti-bacterial or anti-mildew effects and long-lasting effects, but photocatalysis must rely on ultraviolet light, water, air and other conditions, such as , in an environment where the indoor ultraviolet light source is not sufficient, the antibacterial or antifungal effect will be affected to a certain extent
