Multi-element ion antibacterial macromolecular material additive

Abstract

The invention relates to a multi-element ion antibacterial macromolecular material additive. The multi-element ion antibacterial macromolecular material additive is prepared from the following raw materials in parts by weight: 200 to 500 parts of phenolic resin, 50 to 100 parts of dimethyl phthalate, 70 to 80 parts of stearic acid, 70 to 80 parts of multi-element ion antibacterial agent, 70 to 80 parts of acidified talcum powder, and 70 to 80 parts of water. The multi-element ion antibacterial macromolecular material additive has the advantages that by utilizing the ion antibacterial principle and the micro-electromagnetic field technique principle, a novel high-efficiency antibacterial adding material is prepared; the antibacterial property of the matrix material is effectively improved, the service life is prolonged, the problems of low antibacterial property, short service life, overhigh temperature dependence and the like of the traditional antibacterial material are solved, and the common electromagnetic matrix material meets the social requirements.

Description

technical field [0001] The invention relates to the field of antibacterial materials, in particular to a multi-ion antibacterial polymer material additive. Background technique [0002] Polymer materials are ubiquitous in our lives, and bacteria also seriously threaten the safety of human life and property. More than 17 million people die from bacterial infections every year. In view of the fact that bacteria are becoming more and more serious, people have discovered that antibacterial agents can be added to polymer materials during the research process. These antibacterial agents have a significant preventive and resistive effect on bacteria, but some of these antibacterial agents have Antimicrobial activity is problematic. [0003] The first one: It is found that the quaternary ammonium salt group with a long-chain alkyl group has strong antibacterial properties, but organic small molecule antibacterial agents have the disadvantages of being volatile, difficult to process...

Problems solved by technology

[0005] The second type: cations and segregants in quaternary phosphonium salts have a great influence on the antibacterial activity of polyquaternary phosphonium salts. If a compound with relatively close ions is formed, its antibacterial performance will be reduced

Studies have shown that antibacterial agents containing organotin antibacterial groups have a low killing rate for Gram-negative cells. After monomer copolymerization, the concentration of antibacterial gene groups will decrease, and the antibacterial activity will also decrease.
