Abstract

The invention discloses an antibacterial high polymer material and a preparation method thereof. The antibacterial high polymer material is mainly prepared by the following raw materials according to the parts by weight: 99.45-96.70 parts of high polymer material, 0.05-0.30 parts of addition agent, and 0.05-3.00 parts of quaternary phosphine cation modified clay. The preparation method is as follows: a method of melting processing or direct blending is adopted in preparing the addition agent; the quaternary phosphine cation modified clay is evenly scattered into the high polymer material. The antibacterial high polymer material has the advantages of low cost, wide antibiotic spectrum, high antibacterial efficiency, higher heat resistance temperature, good weather resistance, low toxicity and the like, is an ideal substitute good for Ag-carrying antibacterial high polymer material, and can be applicable to the fields such as household electrical appliances, electrons, medical and sanitary products, building materials, daily necessities or farming industry, etc.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to an antibacterial polymer material and a preparation method thereof. Background technique [0002] Due to the extensive use of various soluble disinfectants and organic antibacterial agents, the incidence of global infectious diseases that were once suppressed has shown a sharp rise. Not only have new pathogenic microorganisms been discovered one after another, but also the mutated populations of known microorganisms are also increasing. More and more, such as SARS, bird flu, mad cow disease and mad cow disease, have caused serious casualties and huge economic losses to humans. Therefore, it is an effective method to develop and use new antibacterial materials with high safety and long-lasting effect. That is to say, long-term and safe antibacterial materials and products are used in places where microbial contamination needs to be prevented, and the method of controlling microbi...
