In order to meet the requirements of the footwear products under different environments, the development of more and more footwear products with different characteristics and functionalities is urgently needed, and the skating on the top of the ice is one of the important requirements.

In the environment with the interface of thin ice, snow, ice water and frozen soil layers, when the sole of the sports shoe is contacted with a wet smooth ground or a ground attached with an ice layer, the ice water is attached to the surface of the sole to form a water film, so that slipping injury is easily caused, therefore, the requirement on the slip resistance of the sole in the ice environment is higher, and the slip resistance is one of important factors directly influencing the service life of the ice-surface shoe and is also a key factor for ensuring safety and comfort. At present, the traditional rubber sole is mainly processed and prepared from natural rubber and partial synthetic rubber, although the basic wear-resisting and anti-skidding effects of the rubber outsole can be achieved, the anti-skidding performance of special interfaces (thin ice, snow, frozen soil layers and lichen pavements) cannot be met, therefore, the sliding friction coefficient of the rubber composition needs to be increased through optimizing and improving the rubber material formula and the mixing and vulcanizing steps, and the high-quality rubber more suitable for manufacturing the anti-skidding sole on ice is obtained.
