Polyquaternium polymer emulsion antibacterial agent, preparation method thereof and application thereof

Abstract

The invention discloses a polyquaternium polymer emulsion antibacterial agent, a preparation method thereof and an application thereof. The polyquaternium polymer emulsion antibacterial agent comprises the following raw material components in parts by weight: 0.3-3 parts of cationic antibacterial monomer, 0.3-0.7 part of initiator, 60-80 parts of water, 1-14 parts of hard monomer, 1-17 parts of soft monomer, 0.1-1 part of waterproof functional monomer, 0.1-0.3 part of crosslinking functional monomer and 0.1-0.7 part of adhesion functional monomer. According to the technical scheme of the invention, the soap-free emulsion synthesis technique is adopted, so that no emulsifier is adopted. The water oxygen-rich pollution can be reduced. The obtained polyquaternium polymer emulsion antibacterial agent is strong in antibacterial performance, free of dissolution, and good in durability. The polyquaternium polymer emulsion antibacterial agent can make up the blank in the market and can be widely applied to the antibacterial treatment of fabric antibacterial finishing, automotive metal and plastic decorative materials, floors, ceramic products and home appliances. Meanwhile, the polyquaternium polymer emulsion antibacterial agent can be applied to the antibacterial and preservative treatment of aqueous coatings, inks, adhesives and the like.

Description

technical field [0001] The invention belongs to the field of polymer antibacterial agents, in particular to a polyquaternium polymer emulsion antibacterial agent and its preparation method and application. Background technique [0002] People are inevitably exposed to various microorganisms in daily life. Due to the roughness of the surface of metal and plastic decorative materials such as textiles, floors, ceramics, home appliances, and automobiles, bacteria are more likely to attach to them, resulting in The pathogenic bacteria are transmitted to the skin surface, and the pathogenic bacteria reproduce in large numbers, and cause great harm to human health through the skin, respiratory tract, digestive tract and blood. The antibacterial treatment of materials is an important means to effectively prevent the growth and reproduction of various bacteria, kill bacteria and prevent bacteria from spreading infection. Conventional quaternary ammonium salt antibacterial agents hav...

AI Technical Summary

Problems solved by technology

For example: Wang Maoli et al. (CN103739786A) synthesized an antibacterial agent with a quaternary phosphonium salt group through a grafting reaction, which has a broad-spectrum, high-efficiency, and lasting antibacterial function, but it has the disadvantages of high cost and difficult large-scale use

Xu Weibing (CN101628952A) obtained a guanidine polymer antibacterial agent by copolymerization of functional guanidine salt, which has the advantages of high efficiency, safety, and easy high-temperature processing, but poor durability

Ren Xuehong et al. (CN103554367A) obtained a halide amine salt antibacterial agent by haloamination of maleic anhydride modified-β dextrin containing double bonds, which has the advantages of mild synthesis conditions, simple and controllable, but the halogenation process releases halogens, which are more toxic Large, the degree of halogenation is difficult to control

Yao Fang et al. (CN101168586A) utilized the quaternization reaction of halogenated phenol groups and tertiary amine groups to obtain a quaternary ammonium salt antibacterial agent, which avoided the problem of small molecule loss and antibacterial property decline

In summary, the above antibacterial agents have a series of problems such as complex synthesis steps, high cost, high toxicity, and poor durability.
