摘　　要：以天然橡胶（NR）为基材，采用γ射线辐射技术对其进行辐射预硫化，研究在不同吸收剂量下，材料力学性能的变化趋势，并评价辐射预硫化对材料最终力学性能的影响。结果显示：辐射剂量为0-100kGy时，NR的格林强度随吸收剂量的增加而提高；辐射预硫化与未辐射预硫化的NR相比，完全硫化后，材料的力学性能相差不大。以上结果表明，在此剂量范围下辐射预硫化对天然橡胶的最终硫化性能没有影响，即可实现NR材料的辐射预硫化，且可保证材料的尺寸稳定性。Natural rubber（NR） was procured by y-ray irradiation. The crosslinking degree and green strength of NR were studied at the different absorbed dose. The effects of y-ray irradiation precuring on the final mechanical property were evaluated. The results showed that the crosslinking degree and green strength of NR were heightened with increasing absorbed dose at 0-100 kGy. The final mechanical properties were not significant different between the irradiation precuring and non-procuring of NR. This results show that the irradiation precuring of NR can be realized.
