High-density polyethylene (HDPE) antibacterial plastic

Abstract

The invention discloses high-density polyethylene (HDPE) antibacterial plastic. The HDPE antibacterial plastic comprises, by weight, 160-165 parts of HDPE, 10-15 parts of formaldehyde, 10 parts of maleated polypropylene (PP), 10-15 parts of wollastonite fibers, 10-15 parts of triethylene tetramine, 10-13 parts of zirconia, 5-7 parts of epoxidized soybean oil, 5-8 parts of phenyl salicylate, 10 parts of magnesium salt whiskers and 10 parts of chitosan-grafted methyl methacrylate. The HDPE antibacterial plastic has good antibacterial performances and a small amount of the HDPE antibacterial plastic can produce good antibacterial effects; plastic mechanical strength is not influenced and a heat deflection temperature, a kinetic temperature and electrical insulation properties of the plastic product are not influenced; and the same type of resins have good compatibility and are not transferred, separated and extracted in the plastic product.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an HDPE antibacterial plastic. technical background [0002] With the development and progress of society and the improvement of material living standards, people have higher and higher requirements for living and working environments, especially hygienic environments. Because plastic has the advantages of light weight, no rust, and good insulation, it is used in many aspects of home appliance production. But in daily life, quite a few harmful bacteria exist and multiply on the surface of plastic products, such as: telephones, washing machines, computers, refrigerators, electrical switches, etc., and cause various diseases through contact; People who come into contact with various bacteria, molds and other microorganisms will become the source of bacterial pollution and disease transmission. However, as people's awareness of health and environmental protection conti...

Problems solved by technology

[0003] At present, there is no special material for antibacterial plastics. The home appliance industry always adds antibacterial agents to the raw materials to prepare antibacterial plastics. The antibacterial effect is formed through the slow release of antibacterial agents. With the release of antibacterial agents, the antibacterial activity is getting smaller and smaller. , antibacterial agents are prone to failure and fail to achieve the purpose of antibacterial, and the release of antibacterial will cause environmental pollution

The cost of the product made in this way is high and the quality is unstable. Although it has antibacterial function, the antibacterial range is small, the duration is short, and there is no anti-mildew effect.
