EPDM／OMMT插层复合型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。在研究EPDM／OMMT插层复合密封材料低温冲击性能的基础上，利用含O型橡胶密封圈的密封装置，采用密封箱内压力监测法对插层复合型三元乙丙橡胶密封圈的低温密封性能进行试验研究。结果表明，低温冲击次数对三元乙丙橡胶密封材料的硬度和弹性无明显影响，EPDM／OMMT插层复合密封材料耐低温冲击老化性能优良；插层复合型三元乙丙橡胶密封圈在不超过－60℃低温下的密封性能优良。

EPDM composites by intercalation are usually used as the sealing materials of especial containers because of its excellent aging and sealing properties.The shock-resistance of low temperature of EPDM intercalation composites was studied.By using the seal structure containing O-ring,the sealing properties of the O-ring of EPDM intercalation compos-ites in low temperature were studied by means of pressure observation of mechanical seal.The result shows that impact times of low temperature has no obvious effect on the hardness and elasticity of EPDM,and the sealing rings of EPDM/OM-MT intercalation composites have excellent sealing properties of low temperature at not more than -60 ℃.
