选取乳聚丁苯橡胶、溶聚丁苯橡胶(C)和溶聚丁苯橡胶(B)3种典型的丁苯橡胶,研究了它们与天然橡胶复合体系的动态力学性能.结果表明,溶聚丁苯橡胶SSBR(B)具有特征的链化学结构,与天然橡胶有良好的混容性.溶聚丁苯橡胶/天然橡胶复合体系生热低,而且具有比较均匀的交联网状结构.
The dynamic mechanical properties of blends of natural rubberrespectively with three kinds of styrene-butadiene rubbers, two solution polymerized styrene-butadiene rubbers: SSBR(B), SSBR(C) and an emulsion polymerized styrene-butadiene rubber:ESSA have been investigated. The results showed that SSBR(B) had characteristic chain structure and the SSBR/NR composite showed a good compatibility and low heat generation under pressure.
