Problems solved by technology

[0003] Thermoplastic elastomer is a material with high elasticity, high strength and high resilience of rubber, and can be processed by injection molding. It is environmentally friendly, non-toxic, and has a wide range of hardness. It also has excellent colorability and soft touch. Excellent weather resistance, fatigue resistance and temperature resistance, but its adhesion to acrylonitrile-butadiene-styrene copolymer is poor, and it is easy to fall off after being injected on the surface of the grip for a period of time, and it cannot provide the effect of damping and shock absorption

Abstract

The invention discloses a rubber-coated ABS thermoplastic elastomer for damping and a manufacturing method of the elastomer. The elastomer is prepared from, by weight, 30-50 parts of thermoplastic polyester elastomers, 20-40 parts of styrene block copolymers, 0-15 parts of extending oil, 5-15 parts of a compatilizer, 0-10 parts of inorganic filler, 0.1-3 parts of a lubricant, 0.1-1 part of an antioxidant and 0.1-1 part of an anti-UV agent. According to the rubber-coated ABS thermoplastic elastomer for damping, by adding the thermoplastic polyester elastomers, the adhesive power of the rubber-coated ABS thermoplastic elastomer to ABS is obviously improved, and accordingly the rubber-coated ABS thermoplastic elastomer more conveniently wraps a grip of an electric tool; by adding the thermoplastic polyester elastomers, the damping and shock absorption effect of the rubber-coated ABS thermoplastic elastomer for damping is obviously improved; by adding the compatilizer, the thermoplastic polyester elastomers are integrally bound, and the separation phenomenon cannot occur.

Description

technical field [0001] The invention relates to the technical field of thermoplastic elastomers, in particular to a rubber-covered ABS thermoplastic elastomer for shock absorption and a manufacturing method thereof. Background technique [0002] The grips of many power tools in life are made of acrylonitrile-butadiene-styrene copolymer (ABS, acrylonitrile–butadiene–styrene copolymer). Power tools will generate strong vibrations during work. In order to It is possible to reduce the potential safety hazards caused by such vibrations, often by injecting a layer of thermoplastic elastomer material (TPE, Thermoplastic Elastomer) on the surface of the grip to provide a better grip. [0003] Thermoplastic elastomer is a material with high elasticity, high strength and high resilience of rubber, and can be processed by injection molding. It is environmentally friendly, non-toxic, and has a wide range of hardness. It also has excellent colorability and soft touch. Excellent weathe...
