Problems solved by technology

Under high-speed and high-strength running-in, thermoplastic polyurethane elastomers will cause certain wear and tear on thermoplastic polyurethane elastomers. The thermoplastic polyurethane elastomers produced in the existing technology have relatively poor wear resistance. The surface of TPU is debonded, which shortens the service life of TPU

Abstract

The invention relates to an anti-static thermoplastic polyurethane elastomer. The anti-static thermoplastic polyurethane elastomer comprises the following components in parts by weight: 70 to 80 partsof polyhexamethylene adipate glycol, 45 to 50 parts of p-phenylene diisocyanate, 20 to 23 parts of dodecyltrimethylammonium bromide, 10 to 13 parts of 1,2-di(4'-hydroxy phenyl)-o-carbadecaborane, 5 to 8 parts of a fire retardant, 4 to 6 parts of an antioxidant, 1 to 2 parts of a lubricating agent and 7 to 10 parts of titanium dioxide powder. According to the anti-static thermoplastic polyurethaneelastomer disclosed by the invention, the original preferable mechanical properties, such as high tensile strength and elongation at break, of the thermoplastic polyurethane elastomer are guaranteedwhile good fire resistance is achieved, and the anti-static thermoplastic polyurethane elastomer has good abrasive resistance, tear resistance, hydrolytic resistance and ageing resistance; according to the environmentally-friendly flame-retardant thermoplastic polyurethane elastomer disclosed by the invention, the V-0 combustion level according to the thickness measured by UL94 being 3.0 mm can beachieved, and the oxygen index reaches 30 or more.

Description

technical field [0001] The invention relates to an antistatic thermoplastic polyurethane elastomer, belonging to the technical field of polymer materials. Background technique [0002] Thermoplastic polyurethane elastomer has good elasticity, wear resistance, low temperature resistance, oil resistance and tensile strength, and is often used to make casters, wire and cable sheaths, seals, synthetic leather, shock absorbers, etc., thermoplastic polyurethane elastomer As a high-performance material, it has been widely used in the field of polymer materials. Under high-speed and high-strength running-in, thermoplastic polyurethane elastomers will cause certain wear and tear on thermoplastic polyurethane elastomers. The thermoplastic polyurethane elastomers produced in the existing technology have relatively poor wear resistance. The surface of the thermoplastic polyurethane elastomer is peeled off, which shortens the service life of the thermoplastic polyurethane elastomer. C...
