环保型橡胶增塑剂的研制及其充油丁苯橡胶的性能

Development of Environmentally-friendly Rubber Plasticizer and Properties of It's Extended SBR

以环烷基油的减压三线馏分油为原料,采用加氢精制-溶剂抽提方法富集芳烃和环烷烃,并脱除有害性多环芳烃,制备芳烃含量高的环保型橡胶增塑剂。采用高性能轿车子午线轮胎胎面胶配方,对填充环保型增塑剂的丁苯橡胶SBR1763与填充芳烃油的SBR1712和填充处理芳烃油(TDAE)的SBR1723进行性能对比。结果表明,SBR1763的理化性能及其硫化胶的物理性能与SBR1723相近。

A new environmentally-friendly rubber plasticizer with high aromatic content was prepared using the third distillate of naphthenic base oil under vacuum as raw material. The aromatic and naphthenic contents were concentrated using hydrogenation method and solvent extraction process,in which the harmful polycyclic aromatic hydrocarbon was removed. Using the tread compound of high performance passenger car radial tire,the aromatic hydrocarbon was removed. Using the tread compound of high performance passenger car radial tire,the new plasticizer was then tested in SBR1763 and the compound was compared with aromatic oil extended SBR 1712 and treated distillate aromatic extract（TDAE） extended SBR1723.The testing results showed that the physical and and treated distillate aromatic extract（TDAE） extended SBR1723.The testing results showed that the physical and chemical properties of SBR1763 and the physical properties of the vulcanized SBR1763 were similar to those of TDAE extended SBR1723. TDAE extended SBR1723.
