近年來，多楔帶在汽車得到普遍應用，而發(fā)動機室的溫度越來越高，有的要求橡膠件能耐１５０℃，瞬間能耐１７０℃．，傳統(tǒng)氯丁橡膠（ＣＲ）顯然達不到要求。由于ＨＮＢＲ過于昂貴，人們在研究發(fā)現小量的油污并不對發(fā)動機前端的皮帶造成損害，可使用較廉價耐熱性好多的三元乙丙橡膠（ＥＰＤＭ）作為多楔帶主體橡膠材料。但ＥＰＤＭ耐磨性，錦湖EPDM KEP-270、高溫抗撕裂和動態(tài)性能不理想，與其它材料粘合差，這些都需要通過改性如添加ＺＤＡ或ＺＤＭＡ和與其它材料并用加以解決。 </p> <p> 汽車Ｖ帶一般用綜合性能優(yōu)異的ＣＲ制造，近年來與上述ＥＰＤＭ多楔帶同樣的原因，開始用ＥＰＤＭ生產，錦湖EPDM KEP-270。但汽車Ｖ帶傳動受力機理與多楔帶有很大不同，對壓縮膠的耐曲撓、耐磨性，抗拉體線繩、織物的黏合性以及帶的橫向剛性比多楔帶有更高的要求。ＧＡＴＥＳ公司推出的ＦｌｅｅｔＲｕｎｎｅｒ汽車Ｖ帶（在中國稱為ＥＸＰｏｗｅｒ），據報道實際使用壽命能達到４０００００km以上其它性能也優(yōu)于ＣＲ汽車Ｖ帶，尤其是耐高低溫性能，可在-５５~１２０℃正常使用，錦湖EPDM KEP-270，做到全天候使用。乙丙橡膠為非結晶橡膠，其抗疲勞性能尤其是抗龜裂增長不是很好。與ＳＢＲ相當。錦湖EPDM KEP-270</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="錦湖EPDM KEP-270,錦湖"

ＨＡＬＬＳＴＡＲ公司開發(fā)的環(huán)保型黏合劑促進劑ＨａＪｌｂｏｎｄＲＸ能夠***增強ＥＰＤＭ與聚酯線的粘合強度。另外添加高３０－４０份白炭黑、使用低門尼粘度ＥＰＤＭ或者降低ＥＰＤＭ配方中促進劑用量也可提高粘合性 </p> <p> 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，并采用過氧化物硫化體系，粘接強度明顯提高，粘接的破壞形式是ＥＰＤＭ硫化膠的內聚破壞?；钚灾鷦┑奶砑?，不僅提高了硫化膠的強度，而且還提高了與金屬的粘接強度。加入２份的Ｓａｒｅｔ６３３與鋼黏合，剪切黏合強度從未加的０.５５ＭＰａ提高到３．４４ＭＰａ，加入２０份可提高到ｌ１ＭＰａ。

電線電纜上主要用于民用和商用建筑的輸入線、建筑用電線、礦用電纜、核電站用電線、風能用線、汽車點火線、控制及信號電纜。ＩＥＣ標準規(guī)定，分體空調機連接電纜不得再使用塑料絕緣電纜，一方面是為了增加柔軟性，同時耐老化性和安全可靠性。近幾年來，國內對橡皮絕緣電線電纜的需求又異乎尋常地多起來，主要是低壓產品，而１ＫＶ以上的橡皮絕緣電纜，除了船用電纜和礦用電纜以外，電力電纜方面則還是極少?，F代國外中高壓橡皮絕緣電纜主要是采用乙丙橡膠絕緣，意大利的乙丙膠絕緣電纜早已做到１５０ｋＶ，１５ｋＶ乙丙膠絕緣電纜已經是美國**主流品種。而我國在這個產品上還是相當落后，船舶及機械產品出口量的增加，要求船用電纜及潤滑油等的標準必須與國際接軌而增加了乙丙橡膠用量。 </p><p> EPDM在發(fā)動機冷卻系統(tǒng)和空調制冷系統(tǒng)密封件中的應用 </p> <p> EPDM用于制作發(fā)動機冷卻系統(tǒng)中的密封圈。此類產品接觸的介質是防凍液、陽光、水、臭氧，使用溫度在-40℃～125℃，短期耐熱溫度可達135℃。此類零件采用的EPDM，硬度（邵氏A）為60～80（制冷系統(tǒng)中應用的圓密封圈為75）；其拉伸強度應在10.5MPa以上；斷裂伸長率一般在175%以上；在伸長率50%下的定伸應力為1～2MPa；在伸長率**下的定伸應力為2～5MPa以上；壓縮變形（150℃，22h）應小于20%；其玻璃化轉變溫度（TR）比較大為-50℃；耐臭氧老化（50pphm,拉伸20%，72h）應無裂紋；對于發(fā)動機冷卻系統(tǒng)中應用的密封件應進行冷卻液試驗（將試樣放于防凍液中，150℃，166h，試驗壓力約0.4MPa），其硬度變化應為±5，拉伸強度變化應為±20%，斷裂伸長率變化應為-15%～20%，體積改變應在±5%；對于空調系統(tǒng)中應用的密封件，應進行制冷劑試驗（將試樣放于PAG、ND8制冷劑中，100℃，70h）其硬度變化**多為±5，拉伸強度變化**多為±20%，斷裂伸長率變化**多為-15%～20%，體積改變應在±5%之內；熱老化試驗（150℃，70h），其硬度變化應為±5，拉伸強度下降應小于10%，伸長率的下降不能超過10%。第三二烯烴類型的單體是通過乙烯和丙烯的共聚，在聚合物中產生不飽和，以便實現硫化。</p><div

ＥＰＤＭ的硫化速度較慢，耐油性及粘合性較差，若使其與橡膠如天然橡膠（ＮＲ）、丁腈橡膠（ＮＢＲ）、丁基橡膠（ＩＩＲ）、甲基乙烯基硅橡膠（ＶＭＱ）、氯磺化聚乙烯（ＣＳＭ）、氯丁橡膠（ｃＲ）、氯化聚乙烯（ＣＰＥ）等并用改性，可以很好地綜合不同種類橡膠的優(yōu)異性能，改善各自的不足。一方面，ＥＰＤＭ可以改善其他膠種的耐熱性、耐低溫性、耐臭氧及耐水蒸氣性能等；另一方面，又會使ＥＰＤＭ本身的加工性、耐油性和粘合性得到提高。因此，ＥＰＤＭ與其他橡膠共混改性，可制造出許多具有優(yōu)異性能的新材料。ＥＰＤＭ具有飽和主鏈和低不飽和側鏈，與塑料和其他橡膠共混、動態(tài)硫化改性，可制造多種性能優(yōu)異的新型材料。典型共混物是與聚丙烯（ＰＰ）共混動態(tài)硫化改性制成全硫化ＴＰＶ。在橡膠制品生產過程中，黏合是一個很重要的課題。錦湖KUMHO機械性能優(yōu)異三元乙丙膠</p><p
