摘要
试验了硅橡胶EPDM并用胶及其泡沫的热老化性能。在过氧化物硫化体系下,EPDM用量少于40份的并用胶,在160℃下短时间的热老化性能较好;采用防老配合剂有助于提高耐热性。并用胶的耐热性主要与连续相有较大关系。
Heat aging properties of silicone-EPDM blends and their foam were tested, With peroxide vulcanizing system, the blend of EPDM content lower than 40 phr, had a good heat-aging resistance under 160℃ in hours. The heat-aging properties was related to the continuous phase to some extent. With antioxidant, the heat-aging resistance was improved.
