摘　　要：以天然橡胶为基材作为全钢载重子午线轮胎的过渡层,在0 60 kGy吸收剂量范围内,采用电子束辐照技术对其进行辐射预硫化研究,结果表明,过渡层的格林强度随吸收剂量增加,吸收剂量60 kGy时,胶料的格林强度增幅可达300%;低吸收剂量时,胶料的粘度增加较快,之后吸收剂量虽有增加,但粘度变化不大;辐射预硫化与未辐射预硫化的过渡层相比,热硫化后的力学性能相差不大;过渡层减薄1 mm后,单胎质量平均减少1.5 kg而不影响轮胎的主要性能。In this article, natural rubber is chosen as transitional layer of all-steel load meridian tyre, which is pre-vulcanized by 500 keV E-beam irradiation of up to 60 kGy. The results show that the Green strength of transitional layer increases with the dose, reaching four times at 60 kGy as much as the control （without irradiation）. The viscosity of transitional layer increases rapidly below about 29 kGy, but changes little at higher doses. The final mechanical properties do not differ significantly from those of the control. However, thickness of the natural rubber transitional layer for an average single tire can be reduced by 1 mm （or 1.5 kg）, without obvious adverse effect on the tyre performance.
