Abstract

The invention discloses an anti-microbial TPU material and a preparing method thereof. The anti-microbial TPU material comprises raw materials including, by weight, 1-15 parts of polyether polyol, 15-55 parts of isocyanate, 3-25 parts of a chain extender, 10-35 parts of polyamide, 0.5-6 parts of an anti-microbial agent, 5-40 parts of polyethylene glycol, 0.1-5 parts of a mildew preventive, 0.05-4 parts of an antioxidant, 1-15 parts of organic bismuth, 0.1-8 parts of an antiblocking agent and 0.1-20 parts of a filler. The above raw materials are weighed according to the parts by weight and are evenly mixed; and an obtained mixture is dried, and extrusion is carried out in a casting machine to obtain the anti-microbial TPU material. The anti-microbial TPU material has the technical advantages of high abrasive resistance, good elastic toughness, high hydrolytic resistance, high hardness, high yellowing resistance, high transparency, high tearing strength and the like; the anti-microbial agent, the mildew preventive, the antioxidant and the antiblocking agent are added, and therefore the anti-microbial TPU material has the beneficial effect of being high in anti-microbial and mildew-preventing performance, and wide application of the TPU material in the field with high anti-microbial requirements is promoted; and the anti-microbial TPU material and the preparing method have the wide market prospect.

Description

technical field [0001] The invention relates to the technical field of thermoplastic polyurethane elastomer materials, in particular to an antibacterial TPU material and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane elastomer (TPU) is a kind of elastomer that can be plasticized by heating and can be dissolved by solvent. It has excellent comprehensive properties such as high strength, high toughness, wear resistance, and oil resistance. It has good processing performance and is widely used in national defense, medical treatment, Food and other industries. Thermoplastic polyurethane elastomer, with its excellent performance and wide application, has become one of the important thermoplastic elastomer materials, its molecules are basically linear, with no or little chemical crosslinking. There are many physical cross-links formed by hydrogen bonds between the linear polyurethane molecular chains, and the hydrogen bonds strengthen its s...
