| Abstract: | The conditions for the co-vulcanization of NR-BR/EPDM blends and the effect of EPDM amount added on the properties of the blends were studied. The results showed that when the recipe was NR-BR/EPDM(70/30) 100 phr, carbon black 60phr ,zinc oxide 4phr, DS activator 2.5 phr ,accelerator 2.5 phr, vulcanizing agent 2.5 phr and other additives 10phr, the blends had good comprehensive properties, including the high ultimate strength, elongation and adhesion property, excellent heat aging and ozone resistance . The processing of the blends was simple and suitable for mass production. |
