Abstract

The invention relates to a thermoplastic elastomer for a suction disc and a preparation method thereof; the elastomer is prepared by the following materials by weight proportion: 0-20 percent of polypropylene, 1-5 percent of compatilizer, 10-30 percent of SEBS, 20-50 percent of white oil, 10-30 percent of light activated calcium carbonate and 0.1-0.5 percent of antioxygen; the preparation method comprises the following steps: raw materials are weighted according to weight proportion: the SEBS and the white oil are arranged in a strong mixing machine to be mixed uniformly, and then other raw materials are added and are mixed for 2-5 minutes, and then discharging is carried out; the raw material which is mixed uniformly is placed in a screw compressor and is extruded and granulated. The invention has the characteristics that the prepared TPE not only can regulate the rigidness, but also has good mechanical performance, and the thermoplastic elastomer can be directly injection-molded into various suctions and mainly applied to adornments.

Description

technical field [0001] The invention relates to a thermoplastic elastomer that can be used for suction cups and a preparation method thereof. The elastomer has the characteristics of excellent resilience and can be directly injected into various suction cup products, belonging to the technical field of thermoplastic elastomers. Background technique [0002] The thermoplastic elastomer (TPE) materials currently on the market for suction cups mainly have the disadvantages of poor elasticity and high price. Therefore, the development of such elastomers has great market potential. The TPE material prepared by this method can not only adjust the hardness, but also has very good mechanical properties. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a thermoplastic elastomer that can be used for suction cups and a preparation method thereof in order to overcome the above-mentioned defects of the prior art. [0004] The object of the present i...
