| The effect of N,N′-m-Phenylene Bismaleimide (HVA-2) on the property of the natural rubber based on the sulfur curing system was investigated in this paper. The results indicated that the Coefficient of Thermal Oxidative aging and fatigue was first increased and then decreased. The cross-linking density was increase gradually With the increase of aging time. Make a general observation, when the Concentration of HVA-2 is approximately 1phr, the vulcanizate exhibited a good comprehensive performance. |
