摘要
以填充聚硅氮烷的室温硫化型硅橡胶（ＲＴＶ），在室温下硫化制得的硫化胶，与常规填充ＳｉＯ２的ＲＴＶ硫化胶进行了比较，试验结果表明，前者的物理机械性能优于后者；热老化性能（热空气２５０℃下，经４８ｈ），前者保持柔软，拉伸强度保持原来的７０％以上，而后者则完全老化，丧失性能。
The mechanical properties and heat stability of room temperature vulcanized silicone rubber were improved by polysilazane. The results showed that the rubber test pieces were still soft and maintained above 70 % of their original tensile strength after hot air aging test at 250 ℃ for 48h.
