Broad-spectrum long-acting antibacterial coating spraying agent and preparation method thereof

Abstract

The invention relates to a broad-spectrum long-acting antibacterial spraying agent convenient to use and a preparation method thereof. The spraying agent comprises the following raw material components in parts by weight: 25 parts of a polymer emulsion, 1-5 parts of a nano-silver antibacterial agent, 1-5 parts of a nano-zinc antibacterial agent, 0.5-3 parts of zeolite powder, 3-5 parts of an organosilicon waterproofing agent, 2-10 parts of a waterborne polyurethane adhesive, 0.2-1 part of a nonionic dispersant, 0.5-0.8 part of an organic guanidine antibacterial agent, 0.4-0.6 part of a chitosan antibacterial agent, 0.1-0.2 part of an organosilicon antifoaming agent, 0.1-0.4 part of an organosilicon substrate wetting agent, 0.2-0.5 part of a coalescing agent, 0.2-0.5 part of a pH regulatorand 20-45 part of ultrapure water. The polymer emulsion is a mixture of a polyacrylic acid emulsion and a polylactic acid emulsion in a weight ratio of 3:1, can perform broad-spectrum sterilization for a long time, is high in bactericidal power, free of toxic and side effects and convenient to use, is suitable for families and public places including humid and hot environments, can create an effective sterile environment, and guarantees sanitation and health of people.

Description

technical field [0001] The invention belongs to the field of antibacterial technology, and in particular relates to a broad-spectrum long-acting antibacterial coating spray that is convenient to use and a preparation method thereof. Background technique [0002] At present, bacteria include a broad spectrum of common fungi and pathogenic bacteria. Pathogenic bacteria include Escherichia coli, Staphylococcus aureus, Candida albicans, etc. The impact is relatively large, and bacteria and viruses still have a spreading effect during the activation period of the surface of the object. According to relevant reports, the new coronavirus can stay and survive on the doorknob, and the surface of the fabric, stainless steel, plastic products, paper towels, glass products, etc. It is active, and the survival time varies from 2h to 120h. During this period, the contact transmission between humans and animals is highly contagious, and germs and microorganisms are one of the parasitic hos...

Problems solved by technology

[0005] In public places and homes, the commonly used disinfection and sterilization methods are wiping and spraying. Use 84 disinfectant or medical alcohol to spray and wipe floors, furniture, objects, etc. There is also a soaking method. Use drift powder or 84 disinfectant to disinfect items such as Soak towels, rags, etc.; the disadvantages of the above-mentioned methods and measures are that they are frequently operated, the effect is relatively short-lived, and news of safety accidents caused by improper use appear in the newspapers. exist
