用石油树脂代替古马隆树脂作橡胶软化剂的研究

Study on Ptroleum Resin Substituting Cumarone Resin as Rubber Softener

将等量的石油树脂和古马隆树脂分别配制成橡胶胶料，在同等条件下炼胶、硫化，按照橡胶软化剂的性能采用古马隆树脂胶的分析标准进行检测。经实验数据的对比分析，证实了石油树脂作为橡胶软化剂，完全可以代替古马隆树脂，而且优于古马隆树脂。

Rubbet-sampls were Prepared respectively with petroleum resin and cumarone resin and then processed and vulcanized at the same condition performance mearsurement was conducted with the testing stardards for cumarone resin in accordance with the properties of rubber softener Based on compararative analysis on the experimental dates,petroleum resin was proven to be a goodsubstitute for cumaronc resin as rubber softener and petroleum resin was better than cumarone resin.
