Problems solved by technology

[0004] At present, most of the antibacterial agents used in plastics are nano-silver or artificially synthesized oxides or composite oxides. The cost is high, and the synergy between the carrier material and the antibacterial metal is poor, and the preparation process is complicated, which greatly restricts its usage and application range.

Abstract

The invention discloses an antibacterial plastic containing a natural antibacterial agent. The antibacterial plastic is composed of, by weight: 50-60 parts of a plastic body, 5-15 parts of a plasticizer, 5-15 parts of a stabilizer, 5-15 parts of a lubricant, and 10-20 parts of the natural antibacterial agent. The antibacterial agent involved in the invention has the characteristics of environmental friendliness, no pollution, low cost, good antibacterial effect and long antibacterial time, and can achieve an antibacterial rate of over 70% on Escherichia coli and Staphylococcus aureus.

Description

technical field [0001] The invention belongs to the field of chemical materials and relates to an antibacterial plastic containing a natural antibacterial agent. Background technique [0002] Antibacterial plastics refer to the addition of one or several specific antibacterial agents to plastics to make plastics inherently antibacterial. Kill or inhibit the reproduction of bacteria on the surface of its products. Compared with conventional chemical and physical disinfection methods, the use of antibacterial plastics for sterilization is efficient, long-lasting, economical and convenient. [0003] At present, the antibacterial agents used in plastics are mainly three series: organic, inorganic and natural. Inorganic antibacterial agents are widely used in antibacterial plastics due to their long antibacterial effect and high temperature resistance, which can adapt to plastic processing. Silver zeolite is currently the most commonly used inorganic antibacterial agent for pl...
