According to the theory of sliding of molecular chains, rubber chains that adsorb on the surface of carbon black have certain activities. At initial state, rubber chains with different lengths attach to the surface of Theory of sliding of molecular chains carbon black via physical adsorption. When the stress acts, rubber chains slide on the surface of CB particles, and the majority of chain segments elongated among the CB particles endure the stress. With the increase of the stress, rubber chains will continue to slide, make rubber chains highly oriented and promotes stress redistribution, thereby increasing the stress bore and modulus and stoping the molecular chains fracture caused by molecular chains concentration. Rubber compound shrank after the external force was revoked. After a long-time recovery, the adsorption and desorption reached a new dynamic balance because of thermal motion of rubber chains, which makes the lengths among carbon black particles and rubber compound chains redistributed, and rubber compound recovered or closed to the initial state. |
