Problems solved by technology

[0003] However, although the current conventional bactericidal coatings can have certain killing effects on fungi such as Escherichia coli and Staphylococcus aureus by introducing organic compound bactericides or silver ion bactericides, this type of bactericidal coatings is for smaller The volume of the virus cannot be killed in large quantities; therefore, the current conventional bactericidal coatings have problems such as poor killing effect on viruses

Abstract

The invention is applicable to the technical field of coating, and provides bacterium and virus killing coating as well as a preparation method and application thereof. The coating is prepared from the following components: waterborne acrylic emulsion, a thickening agent, a dispersing agent, a defoaming agent, a coalescing agent, pigment and filler, polyhexamethylene biguanidine, a metal chelatingagent and water. The coating provided by the invention is safe, non-toxic, long-acting and stable, is suitable for indoor coating, and can be used for killing various bacteria and viruses in air, sothat the current situation that the traditional sterilization coating only can be used for bacterium killing and cannot be used for efficiently killing the viruses is improved. According to the invention, the metal chelating agent is added to chelate cations in the polyhexamethylene biguanide; therefore, the polyhexamethylene biguanide can be promoted to kill various electronegative bacteria and viruses, and the bacterium and virus killing effects of the polyhexamethylene biguanide can be continuously and stably released, so that the bacterium and virus killing efficiency of the polyhexamethylene biguanide is improved, and the timeliness of the polyhexamethylene biguanide is enhanced.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a sterilizing and detoxifying coating and a preparation method and application thereof. Background technique [0002] Paint refers to a building material that can be coated on the surface of an object to be protected or decorated. In order to improve the multi-functionality of the paint, functional additives such as fungicides are usually added to the paint to make the paint have a bactericidal effect. [0003] However, although the current conventional bactericidal coatings can have certain killing effects on fungi such as Escherichia coli and Staphylococcus aureus by introducing organic compound bactericides or silver ion bactericides, this type of bactericidal coatings is for smaller A large volume of viruses cannot be killed in large quantities; therefore, there are problems such as poor killing effect on viruses at present in conventional bactericidal coatings....
