摘要: 通过低温熔融法制备了高热稳定性的不溶性硫磺样品, 并对样品的热稳定性能以及橡胶硫化性能进 行了评价, 考察了胶料的焦烧时间、 硫化曲线及力学性能等参数, 用扫描电镜观察了胶料表面的喷霜现象。结果发 现, 实验室制备的不溶性硫磺样品的热稳定性达5 0%以上。在橡胶硫化试验中, 高热稳定性的不溶性硫磺样品延长 了胶料的焦烧时间, 提高了硫化速度, 同时大大减少了胶料表面的喷霜现象, 应用性能达到进口同类产品的性能。

Abstract: High thermal stability insoluble sulfur samples were prepared by lowtemperature melting process, and the performance evaluation was carried out through a rubber vulcanization process with imported product as reference sample. The surface of the rubber "blooming" phenomenon was studied with the scanning electron microscopy. The results show that the thermal stability of insoluble sulfur sample prepared in laboratory is improved by nearly 50%. In the rubber vulcanization test, the rubber scorch time is prolonged by insoluble sulfur samples at low temperatures, and the cure rate at high temperatures is increased. Meanwhile, the "blooming" phenomenon is greatly reduced. The proformances of the insoluble sulfur sample are comparable to those of the reference sample.
