Problems solved by technology

Due to the limitation of raw materials and processing conditions, natural antibacterial agents have not yet been marketed
Organic fungicides have the advantages of fast sterilization speed and wide antibacterial range, but there are problems such as heat resistance and leachate toxicity
Inorganic antibacterial agents are mainly titanium dioxide and nano-silver, which are characterized by good safety and heat resistance, but the price is high and the antibacterial speed is slow

Abstract

The invention discloses guanidine salt antibacterial paint. The guanidine salt antibacterial paint is characterized by being prepared from the following components in parts by weight: 45 to 65 parts of acrylic emulsion, 1 to 5 parts of maleic anhydride, 1 to 10 parts of ethylene glycol, 10 to 30 parts of filling material, 1 to 10 parts of dispersant, 1 to 5 parts of de-foaming agent, 1 to 5 parts of pigment and 1 to 8 parts of guanidine salt type polymer. A coating of the antibacterial paint has good sterilization property and lasting antibacterial property and has relatively good safety.

Description

technical field [0001] The invention relates to an antibacterial coating, in particular to a guanidinium salt antibacterial coating. Background technique [0002] Bacteria exist everywhere in our lives. When our body is infected with a certain amount of pathogenic bacteria, it may cause our body to get sick. There are many ways for harmful bacteria to infect the human body. In addition to eating unclean food and drinks by mistake and airborne transmission, a large part of bacterial infection is caused by contact infection. Bacterial infection on the surface of articles and cross-infection through the surface of articles are important ways of spreading pathogenic bacteria, and even cause epidemics. Antibacterial coatings can form an antibacterial layer on the surface of articles, which can effectively kill and curb the growth and spread of pathogenic bacteria. [0003] Antibacterial paint is a new type of paint with antibacterial and bactericidal functions, which is made by...
