Embodiment

[0021] Produce according to the following process, the ratio of raw materials used in production is with reference to the data in Table 1,

[0022] 1) Accurately weigh SBS, SEBS resin and filler oil according to the mass ratio set by the formula, put them into the mixer and mix them at high speed for 15-20min, then let them stand for 12 hours and set aside;

[0023] 2) Divide the components of the above step 1) into three parts according to the resin / extending oil mixture, solid powder filler, small material, etc. The small material includes POE, compatibilizer, antioxidant and processing aid, and add them separately Weightlessness electronic scale;

[0024] 3) Through the weight loss electronic weighing system, it enters the twin-screw machine evenly from the feeding port according to the preset ratio, and completes the granulation by mixing, underwater granulation, etc.

Abstract

The invention relates to a field hokey injection molding material and a preparation method thereof. The field hokey injection molding material is characterized by comprising the following components by mass percent: 30-40% of SBS (styrene-butadiene-styrene block copolymer) elastomer resin, 5-20% of SEBS (hydrogenated styrene-ethylene-butylene-styrene block copolymer) elastomer resin, 5-12% of POE (polyolefin elastomer), 20-45% of extending oil, 10-40% of solid powder filling material, 0.1-5% of compatilizer, 0.1-2% of antioxidant and 0.01-2% of processing aid.

Description

technical field [0001] The invention relates to a thermoplastic elastomer injection compound and a preparation method thereof. Background technique [0002] In the past 20 to 30 years, thermoplastic elastomers known as the third generation of rubber have sprung up. The advantage of not needing vulcanization greatly simplifies the production process of downstream products, improves production efficiency, and saves production energy consumption. Fields replace traditional vulcanized rubber. There are many developments and industrializations of thermoplastic elastomer injection molding in China, but they mainly focus on the fields of thin products such as tool handle rubber lagging and automotive accessories. For injection molding materials for solid spheres with a thickness of more than 5cm, a hardness of about ShoreA50, and high resilience, domestic manufacturers currently use traditional vulcanized rubber for production. Therefore, this field is still in a blank state, and...
