Abstract

The invention discloses PET (Polyethylene terephthalate) plastic with an antibacterial effect. The PET plastic is prepared from the following materials in parts by weight: 70 percent to 80 percent of PET polyester, 10 percent to 20 percent of glass fiber, 5 percent to 10 percent of a compound antibacterial agent, 2 percent to 3 percent of an antioxidant, 2 percent to 4 percent of a flame retardant and 1 percent to 2 percent of a plasticizer, wherein the compound antibacterial agent is prepared from three materials including nano titanium dioxide powder, nano silver powder and pinitol oil; in the compound antibacterial agent, the parts by weight of the three materials are as follows in sequence: 20 percent to 30 percent of the nano titanium dioxide powder, 10 percent to 20 percent of the nano silver powder and 60 percent to 70 percent of the pinitol oil. By adopting the material proportion, the PET plastic has the advantages of good antibacterial performance and high strength.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a PET plastic with antibacterial effect. Background technique [0002] Polyethylene terephthalate (PET for short), aliased in Chinese as glossy polyester chips, commonly known as polyester resin, is a high polymer, and together with PBT is collectively referred to as thermoplastic polyester or saturated polyester. Ethylene glycol phthalate is dehydrated and condensed. It is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. [0003] PET has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120 ° C. It has excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good, creep resistance, and fatigue resistance. , friction resistance, and dimensional stability are very good, that is, PET plastics are widely used and are imp...
