摘　　要：插层复合型三元乙丙橡胶密封材料因其优良的耐老化性、密封性而被用作特殊部件用包装容器的密封材料。利用含O型橡胶密封圈的密封装置,采用氦质谱检漏法研究插层复合型三元乙丙橡胶密封圈的高温密封性能。结果表明,通过密封结构的合理设计,插层复合型三元乙丙橡胶密封圈在152℃以内的密封性能优良,密封结构表观漏率不大于1×10-7Pa·m3/s。EPDM composites by intercalation are usually used as the sealing materials of especial containers because of its excellent aging and sealing properties. By using the seal structure containing O-ring,the sealing properties of the Oring of EPDM intercalation composites in high temperature were studied by means of mass spectrometer of leak detection and pressure observation. The result shows that the O-ring seal of EPDM intercalation composites has excellent sealing properties below 152 ℃,and its apparent leakage rate is no more than 1 × 10^- 7Pa·m^3/ s.
