ＨＡＬＬＳＴＡＲ公司開發(fā)的環(huán)保型黏合劑促進(jìn)劑ＨａＪｌｂｏｎｄＲＸ能夠***增強(qiáng)ＥＰＤＭ與聚酯線的粘合強(qiáng)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(jìn)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(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?；钚灾鷦┑奶砑?，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。 </p><p> EPDM的填充 </p> <p> 三元乙丙膠屬于補(bǔ)強(qiáng)型的橡膠，并在大量填充時(shí)其物理性能的降低很小，當(dāng)用炭黑作為補(bǔ)強(qiáng)材料時(shí)，拉斷強(qiáng)度隨炭黑粒徑的減少而增大，而與炭黑的結(jié)構(gòu)關(guān)系不大，而定伸應(yīng)力、硬度、門尼粘度等則幾乎只與炭黑的結(jié)構(gòu)相關(guān)，至于撕裂強(qiáng)度，則與炭黑的粒徑和結(jié)構(gòu)兩者均有依賴關(guān)系，其中以粒徑影響較大。 </p> <p> EＰＤＭ中用的**多的軟化劑是石油系油，它的組成特別復(fù)雜。但對(duì)三元乙丙膠具有相容性，它可以像填充劑那樣可以大量添加，主要的支配因素是油的粘度，從揮發(fā)性、膠料門尼粘度、拉斷強(qiáng)度、撕裂強(qiáng)度、熱老化后的拉斷強(qiáng)度和抗吸水性來看，油的粘度高些好，壓縮長久變形、屈撓龜裂增長和高溫拉斷強(qiáng)度等不受油的種類和型號(hào)所影響，但低溫特性隨油的粘度升高而變差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(chǎn)生不飽和，以便實(shí)現(xiàn)硫化。</p><div

</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軟化劑可進(jìn)一步提高ＥＰＤＭ的高溫耐熱性。
