Abstract

The invention relates to antistatic and antibacterial plastics. The antistatic and antibacterial plastics are characterized by being prepared from components in parts by mass as follows: 20-55 parts of thermoplastic plastics, 2-8 parts of a plant antibacterial agent, 1-5 parts of an antistatic agent and 3-7 parts of an auxiliary, wherein the plant antibacterial agent is prepared from plants in parts by mass as follows: 5-10 parts of green tea, 1-2 parts of golden thread, 8-16 parts of isatis roots, 5-12 parts of honeysuckle, 3-6 parts of verbena, 1-5 parts of heartleaf houttuynia herbs and 15-25 parts of wild chrysanthemum flowers. According to the antistatic and antibacterial plastics, the added plant antibacterial agent is extracted from natural plants, the raw materials are cheap, environment-friendly, low-toxic and harmless, the antibacterial rate of the antistatic and antibacterial plastics to staphylococcus aureus and escherichia coli is 99.0% or higher, breeding of bacteria is effectively inhibited, meanwhile, accumulation of static electricity is effectively inhibited, and the condition that static electricity adsorbs bacteria and other harmful substances is avoided. A preparation method of the antistatic and antibacterial plastics is simple and facilitates industrial production.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to an antistatic and antibacterial plastic and a preparation method thereof. Background technique [0002] There are all kinds of microorganisms in nature. In daily life, microorganisms are closely related to people. However, some bacteria, fungi, viruses, etc., as pathogenic bacteria, seriously endanger human life, health and safety. Facing the increasingly rampant The hazards of pathogenic bacteria, human beings continue to research and explore antibacterial aspects. In recent years, with the development of science and technology and the improvement of people's living standards, the demand for various antibacterial material products has been increasing, of which antibacterial plastic products account for a large proportion, and various daily products, including refrigerators, air conditioners, various Food containers, packaging bags, toys, etc., all use a variety of thermoplasti...
