Antibacterial thermoplastic polyurethane elastomer plastic

Abstract

The invention relates to antibacterial thermoplastic polyurethane elastomer plastic, which comprises the following components: 140 parts of polyurethane, 4 parts of zirconium phosphate, 10 parts of nano titanium dioxide, 15 parts of nano silver oxide, 3 parts of polyhexamethyleneguanidine phosphate, 7 parts of ethylene bis stearamide, 5 parts of liquid paraffin, 1 part of polypropylene grafted carboxylic acid and 2 parts of chlorinated polypropylene. The plastic further comprises 2 parts of ethanediamine and 3 parts of aluminum hydroxide. The plastic provided by the invention is high in strength, high in corrosion resistance, good in weather fastness and high in impact resistance; the heat-proof aging degree of the plastic is reduced; besides, the plastic is capable of resisting ethylene glycol, and is also high in strength and low in pollution on the environment; domestic raw and auxiliary materials and additives are employed, and simultaneously, all environmental protection requirements are met; therefore, the competitiveness of the product in market is greatly improved.

Description

technical field [0001] The present invention relates to a kind of plastic, more specifically relates to a kind of antibacterial thermoplastic polyurethane elastomer plastic. Background technique [0002] Antibacterial plastic refers to the addition of antibacterial agents to plastics to make the plastic itself antibacterial, which can kill or inhibit the bacteria stained on the plastic within a certain period of time. Compared with conventional chemical and physical methods, the use of antibacterial plastics for sterilization Long-lasting, economical and convenient. In life, people inevitably come into contact with various bacteria, molds and other microorganisms, such as telephones, washing machines, computers, refrigerators, electrical switches, etc., which will become sources of bacterial pollution and disease transmission. Because plastic has the advantages of light weight, no rust, and good insulation, it is used in many aspects of home appliance production. At pr...

Problems solved by technology

At present, there is no special material for antibacterial plastics. The household appliance industry always adds antibacterial agents to polypropylene raw materials to prepare antibacterial plastics. The resulting products are high in cost and unstable in quality. Although they have antibacterial functions, they have a small antibacterial range and short duration. And no anti-mildew effect
