| 中文摘要: |
| 采用Harkin Hobbs方程中的分散系数λ对异戊二烯与苯乙烯的三元嵌段共聚物(SIS)和丁二烯与苯乙烯的三元嵌段共聚物(SBS)在IR/CR和IR/BR共混物中的相容作用做了预测,并通过实验进行了验证。结果表明,在IR/CR共混物中加入SIS或SBS后可明显地增大Mooney-Rivlin方程中的常数2C1,2C2以及橡胶在溶胀体系中的体积分数vk,同时改善共混物的力学性能;而在IR/BR共混物中加入SIS后,对网络结构参数和共混物的力学性能没有明显影响,预测与验证结果显示出一致性,证实了该方法预测的正确性。 |
| 英文摘要: |
| The compatibility of isoprene-styrene terpolymer(SIS)and butadiene-styrene terpolymer(SBS)to IR/CR blend or IR/BR blend was predicted with the dispersion coefficient λ in Harkin-Hobbs equation and verified by the test. The results showed that the constants 2C1 and 2C2 in Mooney-Rivlin equation and the volume fraction of rubber in the swelling system increased,and the mechanical properties improved by the addition of SIS or SBS to IR/CR blend;the addition of SIS to IR/BR blend had no significant effect on the parameters of network and the mechanical properties of blend. There was no difference between the predicted results and the test results confirming the predicting method. |
