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.
[0061] In Example 1-Example 6, the ...
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.
