Problems solved by technology

The bonding force between the high-performance wear-resistant agent used in this invention and the EPDM matrix is ​​not strong. When subjected to external frictional force, although the wear-resistant agent can carry most of the friction load, it will be removed from the EPDM rubber. precipitation, resulting in a sharp decline in the wear resistance of the sole material, in addition, the sole material also has the problem of poor heat aging resistance

Description

Technical field: [0001] The invention relates to a shoe sole material, in particular to a wear-resistant and heat-resistant EPDM shoe sole material and a preparation method thereof. Background technique: [0002] EPDM is a kind of general-purpose synthetic rubber made of ethylene and propylene as the main raw materials, and a small amount of non-conjugated diene is polymerized under the action of Zeigler-Netta catalyst. The English abbreviation is EPDM. Diene has a special structure, and only one of the two bonds can be copolymerized. The unsaturated double bond is mainly used as a cross-link, and the other unsaturated one will not become the main chain of the polymer, but will only become a side chain. The main polymer chain of EPDM is fully saturated, which makes EPDM resistant to light, oxygen, and especially ozone. EPDM is non-polar in nature, resistant to polar solutions and chemicals, has low water absorption, and has good insulating properties. In the production pro...
