2.過(guò)氧化物硫化時(shí)要加入防老劑才能使硫化中生成的碳．碳鍵的耐熱老化性能充分發(fā)揮，錦湖模壓用EPDM。典型的聚合型喹啉防老齊ＵＴＭＱ（ＲＤ）對(duì)過(guò)氧化物硫化的干擾**小（模量下降較小，壓縮長(zhǎng)久變形增大較小），但是更強(qiáng)的自由基捕捉型防老劑４４５（二烷基二苯胺）卻可達(dá)到更好的高溫老化后物理性能。防老劑４４５和防老劑增效劑ＭＢＺ搭配使用提供了比較好的空氣老化后綜合性能保持率。ＥＰＤＭ過(guò)氧化物交聯(lián)體系中加入含氯聚合物如ＣＲ、ＣＳＭ等可進(jìn)一步提高ＥＰＤＭ硫化膠的抗老化性能。ＣＲ、防老劑４４５和防老劑增效劑Ｍ舊Ｚ三者并用可使ＥＰＤＭ獲得比較好的耐熱效果。 </p> <p> 乙烯基硅烷偶聯(lián)劑Ａ１７２的加入有助于提高ＥＰＤＭ高溫老化后的伸長(zhǎng)率保持率。使用乙烯基硅烷還能使ＥＰＤＭ電纜橡皮膠料在水浸漬期間保持電絕緣性能，乙烯基硅烷偶聯(lián)劑能改善聚合物與填料的結(jié)合強(qiáng)度，防止浸入，從而使ＥＰＤＭ保持了很好的電性能。ＥＰＤＭ配合中，錦湖模壓用EPDM，錦湖模壓用EPDM，如將ＬＥＰＤＭ替代配方中的石蠟油類(lèi)軟化劑可進(jìn)一步提高ＥＰＤＭ的高溫耐熱性。普通牌號(hào)的乙丙橡膠即使不加入耐熱型防老劑，也具有良好的耐高溫性能。錦湖模壓用EPDM</p><div

ＥＰＤＭ與金屬黏合一般采用采膠粘劑法，直接粘接法中二丙烯酸鋅（ZDMＡ）***。研究結(jié)果表明，采用采用ＳＡＲＴＯＭＥＲ的Ｓａｒｅｔ６３３體系膠粘劑用于ＥＰＤＭ與金屬的粘接，并采用過(guò)氧化物硫化體系，粘接強(qiáng)度明顯提高，粘接的破壞形式是ＥＰＤＭ硫化膠的內(nèi)聚破壞。活性助劑的添加，不僅提高了硫化膠的強(qiáng)度，而且還提高了與金屬的粘接強(qiáng)度。加入２份的Ｓａｒｅｔ６３３與鋼黏合，剪切黏合強(qiáng)度從未加的０.５５ＭＰａ提高到３．４４ＭＰａ，加入２０份可提高到ｌ１ＭＰａ。三元乙丙橡膠的分子量及分布可以通過(guò)凝膠滲透色譜法使用二氯苯作為溶劑在高溫下（150℃）測(cè)量而得。</p><div
