摘要

采用火焰燃烧法合成了CeO₂纳米颗粒(CeO₂-FSP),以其作为耐热剂与硅橡胶配合使用,以市售CeO₂作为对比,进行了热失重、热老化前后机械性能和全反射红外光谱等测试,研究CeO₂-FSP对硅橡胶耐热性能的影响。结果表明:CeO₂-FSP具有小粒径且粒径大小分布均匀,同时具有较高的结晶度,在硅橡胶中有良好的分散效果,能提升硅橡胶的机械性能,通过对硅橡胶的耐热性能探究发现CeO₂-FSP对硅橡胶的耐热提升具有显著的效果。

Abstract

CeO₂ nanoparticles (CeO₂-FSP) were synthesized by flame spray pyrolysis (FSP),and used as a heat-resistant agent in conjunction with silicone rubber.Tests such as thermogravimetric analysis,mechanical properties before and after thermal aging,and total reflection infrared spectroscopy were conducted to investigate the effect of CeO₂-FSP on the heat resistance of silicone rubber and compared with commercial CeO₂.The results showed that CeO₂-FSP had small particle size with a uniform distribution and high crystallinity.It exhibited good dispersion in silicone rubber and could enhance the mechanical properties of silicone rubber.The investigation of the heat resistance of silicone rubber revealed that CeO₂-FSP significantly improved the heat resistance of silicone rubber.
