Problems solved by technology

[0002] Due to its special purpose, sports shoes require the sole rubber to have wear resistance, anti-slip performance, and good folding resistance. However, the rubber used in current sports shoes is mainly formulated with isobutylene containing active bromine. -Isoprene copolymer elastomer is the main material. This kind of rubber sole is very unstable in the production process. At the same time, due to the large shrinkage of this material, the sheet is not smooth, and the thickness of the sheet is not easy to control; the sole rubber is in In the later vulcanization process, due to the strong airtightness of the material, poor fluidity, and large shrinkage, factors such as color overflow are difficult to control, poor exhaust, etc., affect production efficiency and increase the defective rate
Although the sole rubber has a good performance in anti-slip performance, it has certain deficiencies in elasticity and wear resistance; the sole of the sports shoe is easy to slip during repeated bouncing and running, and the sole wears out quickly and loses its elasticity.
