Embodiment Construction

[0010] The present invention will be further described below in conjunction with the examples.

[0011] The high resilience TPE material provided by the invention comprises the following components in parts by weight: SEBS 80-120, white oil 60-130, polypropylene 20-40, slip agent 0.3-0.8, and stabilizer 0.2-0.3.

[0012] In this embodiment, the SEBS is one or more of SEBS6151, SEBS YH-501, and SEBS602T.

[0013] In this embodiment, the slip agent is one or more of erucamide and silicone masterbatch.

[0014] In this embodiment, the stabilizer is a 1:1 mixture of the main antioxidant 1010 and the auxiliary antioxidant 168.

[0015] The processing method is as follows: firstly mix the white oil and SEBS in a high-speed mixer at a slow speed for 2-3 minutes, then mix with other raw materials and additives for 2-3 minutes, and then add it into a twin-screw extruder, wherein the twin-screw The length-diameter ratio of the extruder is 24:1, the processing temperature is 240-260° C...

Abstract

The invention discloses a TPE material with high rebound resilience. The TPE material is prepared from the following components in parts by weight: 80-120 parts of SEBS, 60-130 parts of white oil, 20-40 parts of polypropylene, 0.3-0.8 part of a slipping agent and 0.2-0.8 part of a stabilizing agent. The TPE material has excellent rebound resilience, no toxicity, environmental friendliness, no vulcanization requirement and simple processing process, and can be recycled.

Description

technical field [0001] The invention relates to a high resilience TPE material. Background technique [0002] With the development of synthetic rubber industrial modification technology, today as products pursue high performance, refinement, specialization, high efficiency, low energy, and green environmental protection, there is an urgent need for a product that combines the high elasticity of traditional rubber and the thermoplastic processability of resin. s material. [0003] Most of the existing TPE materials use traditional vulcanized rubber, which has high strength and good resilience, but its technological process is complicated, the processing efficiency is low, and the energy consumption is high, and the scraps cannot be reused. SUMMARY OF THE INVENTION [0004] In order to solve the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide a high-resilience TPE material with a simple and efficient process. [0005] In or...
