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。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?。?，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，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。乙丙橡膠為非結(jié)晶橡膠，其抗疲勞性能尤其是抗龜裂增長(zhǎng)不是很好。與ＳＢＲ相當(dāng)。</p><div

8.輪胎用EPDM選擇胎側(cè)：輪胎胎側(cè)是輪胎側(cè)向變形比較大的部位,又與大氣直接接觸,要求膠料的耐屈撓性能、耐臭氧性能和耐天候老化性能良好。在胎側(cè)膠配方中添加少量防護(hù)蠟可對(duì)輪胎胎側(cè)起靜態(tài)防護(hù)作用,但在動(dòng)態(tài)條件下防護(hù)作用**減弱,輪胎在使用一段時(shí)間后胎側(cè)仍會(huì)出現(xiàn)大量龜裂。EPDM具有突出的耐臭氧性能、耐天候性能和耐熱性能，并用少量的EPDM可以***提高胎側(cè)的耐臭氧、耐候性能和耐裂口增長(zhǎng)性能。推薦牌號(hào)：錦湖KEP5560推薦理由：窄分子量分布，超高的ENB含量，硫化速度快，用于輪胎制品時(shí)能夠很好的與NR、SBR等二烯類(lèi)橡膠共混，保證良好的物理性能內(nèi)胎：因具有良好的氣密性能和耐熱性能而在輪胎內(nèi)胎中得到廣泛應(yīng)用"但其加工性能較差存在膠料收縮大&滯后生熱大和加油后易粘輥等問(wèn)題并且老化時(shí)分子鏈傾向于斷裂導(dǎo)致使用后期膠料發(fā)粘嚴(yán)重時(shí)造成內(nèi)外胎粘在一起。三元乙丙橡膠具有優(yōu)異的電絕緣性能和耐電暈性，電性能優(yōu)于丁苯橡膠、氯磺化聚乙烯、聚乙烯和交聯(lián)聚乙烯。機(jī)械性能優(yōu)異三元乙丙膠錦湖客戶至上</p><p
