Plastic antibacterial agent

I. INTRODUCTION With the development of modern economy and the continuous improvement of people's living standards, people's health requirements for living and working environment are also increasing rapidly. At present, the development of the plastics industry has led to a large number of plastic products influx into the market, becoming the most frequently touched items in people's lives and work, and the surface of these plastic products has been bred with a large number of bacteria that threaten people's health at all times. In addition to regular brushing, people use various agents and means to sterilize. Such as: bleaching powder, hydrogen peroxide, ozone, sodium hypochlorite, ultraviolet rays, microwaves, high pressure steam, bactericidal film and so on. However, the common disadvantages of these methods are that they are cumbersome and have a short period of time, they quickly lose their effect due to decomposition or volatilization, and therefore are neither economical nor convenient. Therefore, the market desperately hopes that a kind of measures that can make the plastic products have the function of permanent sterilization can be replaced by them. The high-tech products developed by our factory, plastic antibacterial agents, have solved this unsolved problem. This is a high-tech product of the 1990s and a green product. The international market is currently competing for the development of this type of material, but the domestic is still the first. This technology has obtained national invention patent and invention patent number: ZL92110954.7 II. Bactericidal properties The plastic antibacterial agent is a non-organic drug-based antibacterial agent and is an inorganic substance containing active groups. After adding plastic products, it has Spontaneous, long-lasting antibacterial function.
1. Tested by the Tianjin Center for Disease Control and Prevention [Tianjin Center for Disease Control and Prevention (92) No. 69], with 95-100% antibacterial activity against the following species. Staphylococcus aureus, Staphylococcus aureus, Staphylococcus aureus, Streptococcus A, Streptococcus pyogenes, Streptococcus pneumoniae, Tetracoccus, Neisseria meningitidis, Staphylococcus aureus, Escherichia coli, green Enriched bacillus, enterobacteriaceae, dysentery bacillus, typhoid bacillus, gonorrhea and so on.
2, acute toxicity test LD50 test: non-toxic. [Tianjin Center for Disease Control and Prevention (92) No. 103]
3. Acute skin irritation test: No irritation to skin [Tianjin Center for Disease Control and Prevention (92) No. 104]
4. It can effectively inhibit the growth of moulds on products and prevent microbial aging of plastics and rubber products. Meet the requirements of GB2423.16--90. Third, the antibacterial mechanism The antibacterial mechanism of the antibacterial agent is to implant the active group of the inorganic substrate into the plastic products. These active groups activate the oxygen that is in contact with the surface of the plastic products and become active oxygen. These reactive oxygen species enter bacteria that adhere to the surface of plastic products and oxidize with dehydrogenases, thereby destroying the SH group of dehydrogenases in the bacteria, making it impossible for the bacteria to undergo energy metabolism to be inhibited and then die. Fourth, the technical characteristics 1, out of the current: 325 mesh white ultra-fine material 2, heat-resistant temperature: 250--550 0C
3, specific heat: 0.21kcai/kg.oC
4, thermal conductivity: 0.5kcai/m.hoC
5. Stability: Insoluble in water, 12 months soaking test with moving water and still water, the concentration of active groups in water is only a few PPb.
6, meltability: This product can be well melted with a variety of plastics and rubber materials, no adverse effects on the performance of plastic products. Fifth, the scope of application:
Can be applied to all plastic related industries.
1, the telecommunications industry: telephone shell, switch shell, computer keyboard and so on.
2, chemical building materials: toilet accessories, plastic doors and windows accessories, glass steel tub, wallpaper, paint, paint and other sanitary ware.
3, light industry: toys, refrigerator shell and other daily necessities.
4, food packaging: all kinds of packaging film, packaging boxes, pipes, utensils, food machinery accessories and so on.
5, the textile industry: made of antibacterial fibers and a variety of clothing supplies, carpets and so on.
6, medical equipment: all kinds of medical supplies and medical equipment accessories.
7, paper industry: made of antibacterial paper and so on.
8, rubber industry: all kinds of rubber products and accessories In short, this new high-tech materials, will make the traditional plastic products have undergone tremendous changes.
The company can provide antibacterial plastic masterbatches for various carriers based on the needs of users. (Provided by Anyuan Yuyuan Plastic Antibacterial Agent Co., Ltd., Anshan City, Liaoning Province)
