Medical antibacterial plastic, and preparation method thereof

Abstract

The invention provides a medical antibacterial plastic, and a preparation method thereof. The medical antibacterial plastic is prepared from, by weight, 30 to 60 parts of PE plastic, 12 to 28 parts of polyisoprene, 1 to 3 parts of sodium sulfite, 1 to 4 parts of aluminium nitride whisker, 0.5 to 2 parts of dioctyl sebacate, and 2 to 5 parts of silicon oxide. An antiseptic comprises, by weight, 0.5 to 2 parts of isopropyl myristate, 2 to 5 parts of nanometer copper powder, 2 to 4 parts of octyl 4-methoxycinnamate, 4 to 8 parts of nanometer silver powder, and 1 to 4 parts of 4-quinolone. According to the preparation method, synergistic effect is achieved via combination of the raw materials, reasonable composition is adopted, the suitable antiseptic and preferable using amount of the antiseptic which are beneficial for improvement of antibacterial rate are selected, antibacterial rate on staphylococcus aureus and Escherichia coli is relatively high, and is 99% or higher; the preparation method is simple; the raw materials are cheap; production cost is relatively low; and the preparation method is beneficial for wide popularization.

Description

technical field [0001] The invention belongs to the technical field of plastic products, and in particular relates to a medical antibacterial plastic and a preparation method thereof. Background technique [0002] Antibacterial plastics are a type of plastics that can inhibit or kill bacteria, molds, alcohol mothers, algae and even viruses that are stained on plastics in the use environment, and keep themselves clean by inhibiting the reproduction of microorganisms. At present, antibacterial plastics are mainly obtained by adding a small amount of antibacterial agents to ordinary plastics. [0003] Pathogenic microorganisms such as bacteria and fungi often cause pathological changes in body tissues, seriously threatening human physical and mental health. According to the statistics of the World Health Organization (WHO) in 1998, there were 52 million deaths in the world in 1995, of which about 33 were caused by bacterial infections, and this ratio is still increasing today....

AI Technical Summary

Problems solved by technology

There are many kinds of medical antibacterial plastics. Although some medical antibacterial plastics have good antibacterial effects, they are not suitable for widespread promotion due to the complicated preparation process, high raw material prices, and harsh preparation conditions, resulting in high production costs.
