三元乙丙橡膠是乙烯、丙烯和少量的非共軛二烯烴的共聚物，是乙丙橡膠的一種，以EPDM（EthylenepyleneDieneMonomer）表示，因其主鏈?zhǔn)怯苫瘜W(xué)穩(wěn)定的飽和烴組成，只在側(cè)鏈中含有不飽和雙鍵，故其耐臭氧、耐熱、耐候等耐老化性能優(yōu)異，可***用于汽車部件、建筑用防水材料、電線電纜護(hù)套、耐熱膠管、膠帶、汽車密封件等領(lǐng)域。三元乙丙橡膠是乙烯、丙烯以及非共軛二烯烴的三元共聚物，1963年開始商業(yè)化生產(chǎn)。每年全世界的消費(fèi)量是80萬噸。EPDM**主要的特性就是其優(yōu)越的耐氧化、抗臭氧和抗侵蝕的能力。由于三元乙丙橡膠屬于聚烯(PA66)烴家族，加工性能優(yōu)異錦湖三元乙丙膠，它具有極好的硫化特性。在所有橡膠當(dāng)中，EPDM具有比較低的比重。它能吸收大量的填料和油而影響特性不大。因此可以制作成本低廉的橡膠化合物，加工性能優(yōu)異錦湖三元乙丙膠。因此使用橡膠產(chǎn)品要求性能上年然而，加工性能優(yōu)異錦湖三元乙丙膠，在不能準(zhǔn)確把任何時(shí)候添加材料，都可能成為泄漏、起霜等負(fù)面因素。加工性能優(yōu)異錦湖三元乙丙膠</p><div

耐熱輸送帶廣泛應(yīng)用于冶金、焦化、建材等高溫作業(yè)環(huán)境中，主要輸送燒結(jié)礦石、焦炭和水泥等高溫固體物料，由于冷卻不充分，物料溫度瞬間可達(dá)４００℃～６００℃，部分高達(dá)８００℃以上，因此輸送帶必須具有非常高的耐熱性。三元乙丙橡膠（ＥＰＤＭ）具有優(yōu)良的耐高低溫性能（一５０～１２５℃），在通用橡膠中具有比較好耐熱性能，在１２５℃下可長期使用，在１５０＂Ｃ或更高溫度下短期使用，因此它可用作耐熱輸送帶覆蓋層橡膠材料。 </p> <p> 耐熱輸送帶按ＧＢ／ＴＧＢ／Ｔ２００２１－－２００５《帆布芯耐熱輸送帶》規(guī)定，按試驗(yàn)溫度不同分為四個(gè)等級(jí)：Ｔ１，可耐熱不大于１００℃的試驗(yàn)溫度；Ｔ２，耐熱不大于１２５℃的試驗(yàn)溫度；Ｔ３，可耐熱不大于１５０＂Ｃ的試驗(yàn)溫度；Ｔ４，可耐熱不大于１７５℃的試驗(yàn)溫度。其中Ｔ３和Ｔ４一般需用ＥＰＤＭ制造。 </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。 </p><p> 2.過氧化物硫化時(shí)要加入防老劑才能使硫化中生成的碳．碳鍵的耐熱老化性能充分發(fā)揮。典型的聚合型喹啉防老齊ＵＴＭＱ（ＲＤ）對(duì)過氧化物硫化的干擾**?。Ａ肯陆递^小，壓縮長久變形增大較小），但是更強(qiáng)的自由基捕捉型防老劑４４５（二烷基二苯胺）卻可達(dá)到更好的高溫老化后物理性能。防老劑４４５和防老劑增效劑ＭＢＺ搭配使用提供了比較好的空氣老化后綜合性能保持率。ＥＰＤＭ過氧化物交聯(lián)體系中加入含氯聚合物如ＣＲ、ＣＳＭ等可進(jìn)一步提高ＥＰＤＭ硫化膠的抗老化性能。ＣＲ、防老劑４４５和防老劑增效劑Ｍ舊Ｚ三者并用可使ＥＰＤＭ獲得比較好的耐熱效果。 </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。三元乙丙橡膠在臭氧濃度50×10～，拉伸30%，可達(dá)150h以上不龜裂。</p><div

EPDM門窗密封條&機(jī)柜密封條 </p> <p> 門窗密封條的分類：塑鋼門窗密封條，鋁合金門窗密封條，木門密封條，冷 </p> <p> 庫門密封條，糧庫門密封條，阻燃門窗密封條，玻璃密封條，自動(dòng)旋轉(zhuǎn)門密封條，建筑門密封條，幕墻密封條等。門窗密封條特點(diǎn)：塑鋼門窗密封條是近年來應(yīng)用較廣的新一代門窗，它較普通門窗密封條有更好的防腐性、耐候性、降噪隔熱效果。塑鋼門窗密封條表面光潔，不但具有優(yōu)異的密封防水性能，還起著美觀裝飾的作用。在選材方面，一般要求較高的廠家都選用三元乙丙橡膠或熱塑性三元乙丙橡膠。 </p> <p> 機(jī)柜密封條：電氣柜密封條是由具有良好彈性和抗壓縮變形、耐老化、臭氧、化學(xué)作用、較寬的使用溫度范圍（ -40℃~1 20℃）的三元乙丙橡膠 (EPDM) 橡膠發(fā)泡與密實(shí)復(fù)合而成，內(nèi)含獨(dú)特的金屬夾具和舌形扣，堅(jiān)固耐用 . 在各種電氣柜上起著很關(guān)鍵的作用。三元乙丙橡膠塑煉效果差，缺乏粘著性，不易“吃”炭黑，不宜包輥。錦湖KUMHO高乙烯EPDM</p><p style="text-indent:25px">用納米技術(shù)能夠在分子水平上重組物質(zhì)結(jié)構(gòu)，從而使新材料具有比傳統(tǒng)材料更優(yōu)越的性能。加工性能優(yōu)異錦湖三元乙丙膠</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加工性能優(yōu)異錦湖三元乙丙膠</p><p
