摘　　要：分别研究了N220、N330、N550、N660和N774等5种不同结构的炭黑在相同用量条件下(60phr)对三元乙丙橡胶、乙烯辛烯共聚物(EPDM/POE)混炼胶动态力学性能影响和N330炭黑不同用量对EPDM/POE混炼胶与硫化胶的动态力学性能影响。结果表明,EPDM/POE混炼胶和硫化胶的储能模量均随频率增大而增大,损耗因子随频率增大而减小;在频率相同时,结构度较高、粒径较小的炭黑混炼胶的储能模量和损耗因子较大。EPDM/POE混炼胶和硫化胶的储能模量均随炭黑用量增大而越大。应变小于20%,损耗因子随应变变化不明显,应变大于20%时,损耗因子随着应变增加而快速增加。The effect of five kinds of different structure of N220,N330,N550,N660 and N774 carbon black on the dynamic mechanical properties of EPDM/POE on the terms of the same amount of 60phr and the effect of different amounts of N330 carbon black on the dynamic mechanical properties of the EPDM/POE compounds and vulcanizates are researched.The research showed the storage modulus of the EPDM/POE compounds and vulcanizates increased with frequency increasing while the loss factor decrease with frequency increasing.Black gross rubber with higher structure degree and smaller particle size had a greater storage modulus and loss factor in the same frequency.The storage modulus of the EPDM/POE compounds and vulcanizates increased with amount of carbon black increasing.When the strain was less than 20%,the loss factor did not change significantly with the strain variation;When the strain was greater than 20%,the loss factor increased rapidly with the strain increase.
