Novel antibacterial plastic

Abstract

The invention discloses a novel antibacterial plastic which comprises the following components in percentage by weight: 1-5 percent of nanometer antibacterial particles, 90-98 percent of plastic main ingredient, 1-5 percent of plasticizer, 0-2 percent of coupling agent and 0-2 percent of stabilizer, wherein the nanometer antibacterial particles are nanoscale metal particles, preferably nano zinc particles; the plastic main ingredient is polyvinyl chloride; the plasticizer is an epoxy or citrate plasticizer; the coupling agent is siloxane; and the stabilizer is a phthalate or epoxy stabilizer. The novel antibacterial plastic can generate an effect of killing five common pathogenic bacteria which cause human infections, such as multidrug resistance staphylococcus aureus (MRSA), streptococcus pneumoniae, Candida albicans, Pseudomonas aeruginosa and Aspergillus niger by 99.99 percent and has obvious functions on superbacteria, H1N1 and Legionella Pneumophila. The novel antibacterial plastic has an automatic killing mechanism, is non-toxic and non-irritant to a human body and can be used for preparing catering equipment, toys for children and other products with high antibacterial requirements. Meanwhile, the product also has the advantage of low production cost and has extremely high market promotion value and competitiveness.

Description

technical field [0001] The invention relates to the technical field of plastic materials and discloses a novel antibacterial plastic. Background technique [0002] New requirements in the era of antibacterial: In recent years, there have been endless incidents of bacterial infection and spread hazards. Human beings have a deeper understanding of the importance of antibacterial. Therefore, for 3C electronic products and livelihood products, such as underwear, socks, infant and adult diapers, women's Hygienic products, such as sanitary pads, bathroom and toilet products, such as detergents, hand sanitizers, hand creams, sanitizers, home protective products, such as masks, air conditioning system cleaning filters, medical products, such as bandages, wound stickers The health requirements for cloth, artificial leather, antibacterial and disinfected salt water, etc., and home building materials have been further raised from the environmental protection and safety of raw materials...

AI Technical Summary

Problems solved by technology

Existing antibacterial plastics cannot meet people's needs due to high product cost and unstable quality, especially plastic dining utensils, because of their own characteristics, traditional sterilization methods such as high temperature sterilization cannot be used, and viruses and bacteria attached to the surface cannot be effectively eliminated. Harmful to people's health, so people have an urgent demand for antibacterial plastics with good bactericidal effect, low cost and suitable for wide application

[0004] Studies have shown that when positively charged zinc ions are used to contact bacteria, holes are created due to the tearing of the bacterial cell membrane / wall, making it impossible for bacteria to carry out cell membrane / wall. wall formation affects reproduction
