Abstract

Method of preparing thermoplastic elastomer compound material and product thereof, applying post forming technics. The post forming technics is: first prepare the mold core by the method of injection molding or compression molding; then put the mold core into the mould and produce product with mold core by the compression molding method, taking the mold core out of the product by mechanical crushing, getting the product of hollow thermoplastic elastomer compound material. The post forming method includes following steps: 1) preparing the mold core by the injection molding of the compression molding method; 2) putting the mold core into the mould and producing product with the mold core by the injection molding method; 3) taking the mold core out of the product by mechanical crushing to get the hollow product. 4) the crushed mold core can be reclaimed for recreating use. The thermoplastic elastomer product prepared by the invention provided moulding preparation method is in formula (in mass parts proportioning): thermoplastic elastomer 100parts; thermoplastic plastics 1-50 parts; anti-oxidant 0.5-10 parts; ultraviolet absorbent 0.5-10 parts; lubricants 0.1-5.0 parts.

Description

technical field [0001] The invention relates to a method for preparing a thermoplastic elastomer composite material and its products, in particular to a thermoplastic elastomer composite material for locomotives and vehicles with high pressure resistance and high resilience and a molding method for its products. The present invention also relates to the application of the above-mentioned materials, which are mainly used as elastic materials for the cushion pads and damping pads of rolling stock couplers. Background technique [0002] The coupler buffer device is a vehicle component used to connect vehicles, locomotives or motor vehicles to each other, transmit traction, braking force and ease longitudinal impact. It consists of a coupler, a buffer, a coupler frame, and a slave plate as a whole, and is installed in the traction beam at the end of the vehicle chassis. The buffer is a component used to alleviate the longitudinal impact of the rolling stock. The working princip...
