Abstract

The invention discloses an antibacterial plastic, which is composed of, by weight: 40-60 parts of a plastic body, 10-15 parts of a plasticizer, 10-15 parts of a stabilizer, and 20-40 parts of an antibacterial agent. The antibacterial plastic provided by the invention has potent and lasting antibacterial and bacteriostatic effects, can reach an antibacterial ratio up to 90% on Escherichia coli and Staphylococcus aureus, and the antibacterial time is long. With a low pipe production cost, the antibacterial plastic can be widely used in refrigerators, washing machines, televisions and other household appliance industries.

Description

technical field [0001] The invention belongs to the field of chemical materials and relates to an antibacterial plastic. Background technique [0002] With the rapid development of industry and the continuous improvement of people's living standards, people's awareness of product safety and hygiene is increasing day by day. In life, people inevitably come into contact with various bacteria, molds and other microorganisms, such as telephones, washing machines, computers, refrigerators, electrical switches, etc., which will become sources of bacterial pollution and disease transmission. This requires that all kinds of home appliances used in our life have the effect of antibacterial and antimildew. [0003] At present, antibacterial plastics have begun to be used in large household appliances (such as refrigerators, etc.). The development and production of home appliances that can inhibit and kill harmful bacteria (such as antibacterial refrigerators) will drive China's home...
