Problems solved by technology

In order to improve the feel of handles and toy products, a layer of rubber is often used to cover the surface, but because the two phases of ABS and rubber are incompatible, the rubber is simply covered on the surface, the bond is not firm, and it is easy to slip and fall off

Abstract

The invention relates to a thermoplastic elastomer material, which comprises: SEBS-A 10-40%, SEBS-B 10-40%, plasticizer 20-50%, TPU 5-15%, solvent 1-8%, anti-oxidant 0.1-0.5%, and inorganic mineral 1-10%. Wherein, the preparation method comprises: selecting materials to put into strong-mixing machine for 2-5min; out feeding; extruding and granulating in the screw machine with 180-600r / min rotation speed at 160-240Deg. This invention changes the polarity of TPE, obtains well sticking effect, and has no harm to environment and human.

Description

technical field [0001] The invention relates to a thermoplastic elastomer material and a preparation method thereof, in particular to a modified transparent TPE material that can be bonded to ABS in secondary injection molding, and can be used for injection molding various handles and toy products, belonging to thermoplastic elastomer materials technology field. Background technique [0002] ABS resin is widely used in various handles and toy products due to its good fluidity, rigidity, chemical resistance, and gloss. In order to improve the feel of handles and toy products, a layer of rubber is often used to coat the surface. However, due to the two-phase incompatibility of ABS and rubber, the rubber is simply covered on the surface, and the bond is not firm, and it is easy to slip and fall off. Contents of the invention [0003] The object of the present invention is to provide a thermoplastic elastomer material that can be bonded to ABS in secondary injection molding a...
