The mechanical properties of both radiation (RVNRL) and peroxide vulcanized natural rubber latex (PVNRL) are low when compared to sulphur prevulcanized natural rubber latex (SVNRL). This paper deals with the effect of peroxide on the mechanical properties of radiation vulcanized NR latex film. Here, n-butyl acrylate (n-BA) was used as sensitizer and t-butyl hydroperoxide (t-BHPO) as co-vulcanizing agent during irradiation. It was found that the addition of t-BHPO is more practical method to reduce the vulcanization dose. Thermal ageing study showed that the best retention in tensile properties was shown by RIPV vulcanizates.

使用叔丁基过氧化氢增强辐射硫化天然橡胶胶乳的机械性能

与硫磺预硫化的天然橡胶胶乳（SVNRL）相比，辐射（RVNRL）和过氧化物硫化的天然橡胶胶乳（PVNRL）的机械性能均较低。本文研究了过氧化物对辐射硫化NR胶乳膜力学性能的影响。在此，在照射过程中，丙烯酸正丁酯（n-BA）被用作敏化剂，而氢过氧化叔丁基（t-BHPO）被用作助硫化剂。发现添加t-BHPO是降低硫化剂量的更实用的方法。热老化研究表明，RIPV硫化橡胶显示出最佳的拉伸性能保持率。
