Description

[0001] Technical field: [0002] The invention belongs to the field of non-vulcanized rubber materials, and in particular relates to a self-healing non-slip non-vulcanized rubber material and a preparation method. [0003] Background technique: [0004] Rubber materials are commonly used in all aspects of life and industrial manufacturing. Many fields require rubber materials to have high anti-skid and wear resistance. Therefore, the friction coefficient and wear of rubber are the key indicators for judging the use of rubber materials in high friction environments. At present The most effective method is to add nano-fillers to rubber materials, among which nano-silica is the most commonly used. For example, patent CN 103857743 B provides a rubber composition that can be used for studless tires. The rubber composition includes rubber, aromatic oil, silica, and carbon black. This method of processing rubber tires effectively improves the friction performance of rubber, especiall...
