摘要

以天然橡胶/丁苯橡胶（Natural rubber/styrene butadiene rubber，NR/SBR）并用体系为基材，采用电子束辐照技术对其进行辐射预硫化，研究了不同吸收剂量下，材料交联度、硫化速度及格林强度的变化趋势，并评价了电子束辐射预硫化对材料最终力学性能的影响。结果表明：NR/SBR并用体系的交联度和格林强度随吸收剂量的增加而提高，热硫化速度基本不受吸收剂量的影响，可实现NR/SBR并用体系的辐射预硫化；辐射预硫化与未辐射预硫化的NR/SBR相比，完全硫化后材料的力学性能相差不大。

Abstract

Natural rubber(NR)/styrene butadiene rubber(SBR) blends was precured by electron beams(EB) irradiation. The crosslinking degree、green strength and heat curing speed of NR/SBR were studied with different absorbed doses. And the effects of EB irradiation precuring on the final mechanical properties were evaluated. The results show that the crosslinking degree and green strength of NR/SBR was improved respectively while the heat curing speed was not changed with increasing absorbed doses. The final mechanical properties were not significantly changed between the irradiation precuring and non-irradiation precuring of NR/SBR. The EB irradiation precuring of NR/SBR may be suitable for rubber process.
