摘　　要：研究了氧化铈对硅橡胶热老化性能的影响。结果表明,这种自制的纳米级氧化铈可有效提高甲基乙烯基硅橡胶的耐热空气老化性能,DTA-TG试验证明这种氧化铈的加入可明显提高硅橡胶的热反应温度,对颜色有要求的耐高温硅橡胶有实用价值。The effect of CeO2 on the thermal stability of methyl-vinyl silicone rubber was researched. The results showed that MVQ thermal stability was improved by self-prepared nano-CeO2. DTA-TG analysis showed that thermal oxidation temperature was increased by adding Cerium dioxide.
