8.EPDM防水卷材三元乙丙橡膠(EPDM)卷材是目前世界公認的性能比較好異的防水材料，近年來,橡膠防水卷材在我國迅速發(fā)展,已成為一種多品種，錦湖 KEP-510，錦湖 KEP-510、多規(guī)格、多檔次及多功能的橡膠制品,防水卷材的應(yīng)用領(lǐng)域很廣，如平屋面和低坡度住宅建筑的屋面工程和地下工程，住宅小區(qū)的停車場的頂板，層間和地下，公用設(shè)施以及游泳池等工程的防水，明挖法地鐵隧道工程中地下結(jié)構(gòu)的主體結(jié)構(gòu)全外包防水和頂板防水，車問及出入口通道，蓋挖法施工的車站頂板防水等。防水卷材作為防水層材料的優(yōu)點和工程應(yīng)用的優(yōu)勢是無可爭辯的。三元乙丙橡膠防水材料分子的耐用年限據(jù)測算可達５４年。三元乙丙橡膠防水卷材彈性好、拉伸性能優(yōu)異、抵抗應(yīng)力變形和基層開裂的能力強，具有高斷裂強度，錦湖

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(cè)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。充油錦湖EPDM三元乙丙橡膠(EPDM)常用依據(jù)不同的性能要求可使用硫黃、過氧化物及樹脂硫化。</p><div

橡膠的擠出成型始于內(nèi)胎成型，逐漸被廣泛應(yīng)用于汽車用內(nèi)飾材料、外飾材料、建筑用材料、管道、電線等領(lǐng)域特別是由于三元乙內(nèi)橡膠的擠壓物表面光滑干凈，主要用于維持形狀等物理特點要求高的地方， </p> <p> 為制造良好的KP三元乙丙橡膠擠出物，必須考慮如下要求特點。 </p> <p> l 分子量 </p> <p> l 分子量分布(MWD) </p> <p> l 乙烯丙烯的組成分布 </p> <p> l 填充劑的種類及擠壓加工性 </p> <p> l 硫化計 </p> <p> 分子量的大小主要反應(yīng)在生膠的門尼上，較低的門尼粘度有助于橡膠的順利擠出，分子量分布寬擠出性能優(yōu)異，乙烯含量對擠出性能會有相對正向的影響，填料方面，炭黑、碳酸鈣相對于白炭黑而言更利于擠出。 </p> <p> 進行擠出加工時主要發(fā)生的問題包括擠壓量、沖模膨脹、形狀維持性、擠壓物的表面狀態(tài)、給料性等，為解決這些問題，必須注意聚合體的選擇以及填充劑的選擇。 </p><p> EPDM汽車傳動帶中的應(yīng)用 </p> <p> 近年來，多楔帶在汽車得到普遍應(yīng)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(xiàn)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、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(chǎn)。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(jù)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，做到全天候使用。普通牌號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。</p><div

style="text-indent:25px">接枝改性是改善乙丙橡膠性能缺點的重要途徑之一，也為制備綜合性能更優(yōu)異的改性乙丙橡膠提供了可能。乙丙橡膠的接枝改性就是通過在其分子主鏈上接枝含有特征官能團的極性支鏈單體，提高聚烯烴基體與其它極性成分界面的結(jié)合力，使其它極性材料得以均勻分散，提高材料的物理性能及產(chǎn)品的性能穩(wěn)定性，從而改善乙丙橡膠的自粘性、互粘性以及相容性。接枝改性乙丙橡膠主要用于改善乙丙橡膠與其它材料的結(jié)合強度、相容性、填料界面的結(jié)合、制品韌性、沖擊強度、低溫脆性及耐熱性等。乙丙橡膠接枝改性技術(shù)主要包括溶液接枝法、熔融接枝法等，近年來又發(fā)現(xiàn)了電子束輻射接枝和直接溶脹接枝等新的接枝方法，為乙丙橡膠接枝改性提供了更***的技術(shù)可行性。三元乙丙的交鏈速度和硫化時間隨著硫化類型和含量而改變。錦湖

在兩種橡膠并用時影響共硫化的因素有橡膠相的混合性，兩種橡膠的硫化特性及配合劑的分散性，據(jù)知，三元乙丙膠與丁苯膠、天然橡膠或聚丁二烯膠等并用時，分散狀態(tài)為微觀不均勻分散，與硫化體系無關(guān)。但ＮＲ／ＳＢＲ、ＮＲ／聚丁二烯并用體系同ＥＰＤＭ并用體系的摻和狀態(tài)基本上都是相同的。因而分散狀態(tài)并不是一個太大的問題，問題在于硫化特性方面，決定因素為橡膠的硫化速度和硫化程度，當(dāng)采用硫化體系時還決定于雙鍵的數(shù)量、位置和分布，此外，還決定于ＥＰＤＭ第三單體的種類。 </p> <p> 當(dāng)三元乙丙膠并用少量不飽和橡膠時強度比較低，其原因在于兩種橡膠的硫化速度不同，二烯類橡膠先行硫化，而ＥＰＤＭ卻還停留在未硫化狀態(tài)，因此，為要提高共硫化性，研究一下如何提高ＥＰＤＭ含量大的膠料的強度是有意義的。錦湖 KEP-510</p> <span style="display:none;"></span><p
