在橡膠制品生產(chǎn)過程中，黏合是一個很重要的課題。它包括橡膠與橡膠、橡膠與金屬和橡膠與纖維織物等之間黏合。乙丙橡膠由于表面缺乏活性，與其它材料粘合困難，尤其是一些在高溫、高負(fù)荷動態(tài)狀態(tài)下使用的制品如汽車傳動帶、空氣彈簧等用常規(guī)的粘合處理方法如ＲＦＬ和“間甲白”直黏體系等，很難達(dá)到滿意的黏合效果，需用特殊或幾種方法配合使用。 </p> <p> ＥＰＤＭ與纖維織物黏合中，纖維表面處理用ＲＦＬ浸漬液中的膠乳一般使用ＣＳＭ、ＢＲ和ＥＰＤＭ等，這在一般靜態(tài)使用的橡膠制品尚可，但高動態(tài)使用時(shí)，其黏合強(qiáng)度顯得不足，解決辦法有：①用特殊膠乳。用高反應(yīng)性的馬來酸酐聚二丁烯膠乳處理，可**提高尼龍、聚酯和芳綸等纖維與ＥＰＤＭ黏合強(qiáng)度。 </p><p>

乙丙橡膠是齊格勒——納塔立體有規(guī)催化體系開發(fā)后發(fā)展起來的一種介于通用橡膠和特種橡膠之間的合成橡膠。１９５０年后納塔（Ｎａｔｔａ）等發(fā)現(xiàn)了新型聚合催化劑，于是采用立體有規(guī)性催化劑進(jìn)行烯烴聚合的研究逐漸開展起來，特別是將石油所大量產(chǎn)生的乙烯、丙烯等烯烴試行聚合，乙烯和丙烯的共聚物特別表現(xiàn)出橡膠彈性。這種聚合物的特點(diǎn)是：在分子排列上很象天然橡膠，但物理性能優(yōu)異，基本原料價(jià)廉。它作為合成橡膠于１９５９年首先由意大利蒙特卡蒂尼（Ｍｏｎｔｉｃａｔｉｎｉ）公司的海洛特工廠商品化，這是所謂（二元乙丙橡膠）。這種橡膠主鏈不含雙鍵，是與以往合成橡膠完全不同的一類橡膠。一方面因該橡膠不含雙鍵致使耐熱性、耐天候性、耐臭氧性和耐化學(xué)藥品性十分優(yōu)越。另一方面由于不含雙鍵的緣故而不能采用硫黃硫化法使之交聯(lián)，但在１９６２年通過加入第三單體的方法而使它變成可用硫黃硫化的橡膠。硫載體硫化膠交聯(lián)密度大，綜合力學(xué)性能較好,長久變形大,耐熱老化性能差。KEP-510錦湖客戶至上</p><p
