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、多規(guī)格、多檔次及多功能的橡膠制品,防水卷材的應用領(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、抵抗應力變形和基層開裂的能力強，具有高斷裂強度、撕裂強度和抗刺穿強度；通過熱焊接能形成強于卷材的接縫；具有高的反射率；卷材不含氯。 </p><p> 8. EPDM密封條 </p> <p> 乙丙橡膠耐老化性好。它是乙烯和丙烯在催化劑作用下共聚而成。該品具有良好的化學穩(wěn)定性、耐熱性、耐酸、耐堿性、耐寒性。對于高壓蒸汽和磷酸脂系用乙丙膠制密封件可得到十分滿意的效果。在礦物油中不宜使用，因易泡漲。乙丙橡膠缺點是在室溫下粘度不好，給加工制造帶來困難。硫化時間也長，為此人們研究了三元乙丙膠，即在橡膠分子側(cè)鏈中引進不飽和鍵，所以可以用硫磺硫化，同時也便于加工。乙丙橡膠綜合物理機械性能介于天然膠與丁苯膠之間，與丁基橡膠類似。使用溫度 -45~1 50℃。在一般的橡膠制品中，乙丙膠件使用壽命**長。目前密封條市場主要以三元乙丙（ EPDM ）橡膠為主，且先后被應用到門窗、機柜、汽車等各種行業(yè)，根據(jù)不同行業(yè)的要求，先后研發(fā)出了特有的門窗密封條、機柜密封條、汽車密封條等產(chǎn)品。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

三元乙丙橡膠的分子量及分布可以通過凝膠滲透色譜法使用二氯苯作為溶劑在高溫下（150℃）測量而得。分子量分布通常被稱為是重量平均分子量與數(shù)量平均分子量的比例。根據(jù)普通和高度支化的結(jié)構(gòu)，這個值通常在2到5之間變化。三元乙丙橡膠的門尼粘度可以反映其分子量的大小，三元乙丙橡膠的門尼粘度范圍通常在20到100之間。 </p> <p> 增加三元乙丙橡膠的分子量，正面影響有：更高的拉伸和撕裂強度，在高溫情況下更高的生坯強度，能夠吸收更多的油和填料（低成本）。但是過高的分子量也會使得橡膠的流動性能變差，這意味橡膠后續(xù)加工會更加的困難，比如更難混煉，更難充模，更難擠出等等，隨著分子量分布的增加，正面的影響有：增加的混煉和碾磨加工性。但是，較窄的分子量分布可以改進硫化速度，硫化狀態(tài)以及注塑行為。三元乙丙橡膠高溫流動性較好，故制造模壓制品時沒有什么困難。KEP-282F錦湖服務商</p><p style="text-indent:25px">三元乙丙是乙烯、丙烯和非共軛二烯烴的三元共聚物。錦湖KUMHO減震用三元乙丙膠</p><p> 硫化類型三元乙丙可以利用有機過氧化物或者硫來進行硫化。但是，相比與硫磺硫化，過氧化物交鏈的三元乙丙用于電線電纜工業(yè)時具有更高的溫度抗性，更低的壓縮形變以及改進的硫化特性。過氧化物硫化的不好的地方就在于更高的成本。正如前面所提到的，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。當三元乙丙與丁基，天然橡膠，丁苯橡膠混合時，在選擇合適的三元乙丙產(chǎn)品時，必須要考慮到下列因素：當與丁基進行混合時，由于丁基具有較低的不飽和度，為適應丁基的硫化速度，比較好選擇相對較低含量的DCPD和ENB含量的三元乙丙。當與天然橡膠和丁苯橡膠混合時，比較好選擇8%到10%ENB含量的三元乙丙，以滿足其硫化速度。三元乙丙橡膠是由乙烯、丙烯經(jīng)溶液共聚合而成的橡膠，再引入第三單體（ENB）。三元乙丙橡膠基本上是一種飽和的高聚物，耐老化性能非常好、耐天候性好、電絕緣性能優(yōu)良、耐化學腐蝕性好、沖擊彈性較好。乙丙橡膠的**主要缺點是硫化速度慢；與其它不飽和橡膠并用難，自粘和互粘性都很差，故加工性能不好。錦湖KUMHO減震用三元乙丙膠</p><p
