Abstract: |
The effects of formulation factors(vulcanization system,activator,reinforcing filler and
plasticizer) on the vulcanization characteristics of ethylene propylene diene rubber(EPDM) compound were
studied. The results showed that the vulcanization system was the main factor determining the vulcanization
characteristics of EPDM compound. The compound with sulfur vulcanization system had fast vulcanization
speed and good comprehensive performance. Since the amount of the reinforcing filler was large and the
active agent participated in the vulcanization reaction,they had a great influence on the vulcanization
characteristics. Carbon black could promote the vulcanization due to its alkaline surface,while silica could
delay the vulcanization due to its acidic surface. The plasticizer did not participate in the formation of
crosslinking bonds and had little effect on the vulcanization characteristics of EPDM compound. |
