摘　　要：研究了普通(CV)、有效(EV)、半有效(SEV)和平衡(EC)四种硫化体系对NR抗硫化返原和硫化胶物理机械性能的影响。结果表明:有效和平衡硫化体系的抗硫化返原性最好;在不同的硫化体系中加入抗返原剂Si69之后,都能有效地提高硫化天然胶的抗硫化返原性和物理机械性能。综合使用性能和抗硫化返原性,以半有效硫化体系较好。In this paper,effects of conventional cure system(CV),effective cure system(EV),semi-effective cure system(SEV),equivalent cure system(EC) on the physical-mechanical properties and cure reversion resistance of cured natural rubber were studied.The results showed: CV had the seriousest cure reversion ,while the EV and EC has the best reversion resistance. After adding Si69 to various cure systems,the reversion resistance of various cure system were improved.
