Embodiment 1- Embodiment 6
[0056] Example 1-Example 6 all adopt the same preparation method to prepare TPE particles, the only difference is that the dosage of each raw material component is different, see Table 2 for details:
[0057] The dosage of each raw material component in the embodiment 1-embodiment 6 of table 2
[0058]
[0059]
[0060] Among the embodiment 1-embodiment 6, the base material is all mixed by the SBS and SEBS that the weight ratio is 2:1, and the toner is all mixed by the phthalocyanine green powder and other auxiliary toners that the weight ratio is 3:1 Other auxiliary toners can be selected according to actual needs to color TPE particles, such as yellow masterbatches and black masterbatches sold by Dongguan Jinsuyan Plastic Technology Co., Ltd. The order number of the talc powder in embodiment 1-embodiment 2, the heavy calcium powder in embodiment 3-embodiment 4 and the wollastonite powder in embodiment 5-embodiment 6 is 800 orders.

Embodiment 7
[0067] The difference between this example and Example 3 is that the oil-locking additive is made by mixing and granulating 11.5g of 2-mercaptobenzimidazole and 85g of polypropylene.
Embodiment 8
[0069] The difference between this example and Example 3 is that the oil-locking additive is made by mixing and granulating 8g of 2-mercaptobenzimidazole and 87g of polypropylene.

Abstract
The application relates to the field of TPE particles, and specifically discloses an aging-resistant TPE particle and a preparation method thereof. An aging-resistant TPE particle is made of raw materials comprising the following parts by weight: a base material mixed with SBS and SEBS; rubber oil; oil-locking additive; filler; toner; antioxidant; anti-aging additive; its preparation The method is as follows: mix the base material with rubber oil, stir evenly and let it stand for 30-60 minutes to obtain a first-class mixture; put oil-locking additives, fillers, toner, antioxidants and anti-aging additives into the first-class mixture, mix homogeneously to obtain a secondary mixture; extrude, pelletize, and dry to obtain TPE pellets. The anti-aging TPE granules of the present application have better aging resistance and longer service life; in addition, the preparation method of the present application is simple to operate, can promote the full reaction of each raw material component, and ensures that the TPE granules have better anti-aging performance.
Description
technical field [0001] The application relates to the field of TPE granules, more specifically, it relates to an aging-resistant TPE granule and a preparation method thereof. Background technique [0002] TPE is the abbreviation of thermoplastic elastomer. It is a material with high elasticity, high strength and high resilience of rubber, and has the characteristics of injection molding. It is environmentally friendly, non-toxic and safe, with a wide range of hardness and excellent coloring. Non-toxic, soft touch, weather resistance, fatigue resistance, temperature resistance, excellent processing performance, no need for vulcanization, and can be recycled to reduce costs, so it is widely used in toys, daily necessities, pipes, building materials, packaging materials, etc. [0003] At present, in the field of artificial turf, TPE particles are often used as filler particles to fill artificial turf fibers to hold down the grass fibers, stabilize the turf, increase friction, a...
