style="text-indent:25px">氫化丁腈橡膠(HNBR)是一種綜合性能極好、極具發(fā)展?jié)摿Φ奶胤N橡膠。氫化丁腈橡膠（HNBR）與腈橡膠（NBR）相比，其分子主鏈上的碳-碳雙鍵（C=C）少，化學(xué)結(jié)構(gòu)穩(wěn)定，具有優(yōu)異的耐油、耐腐蝕，耐低溫、耐高溫、耐熱氧老化、耐動(dòng)態(tài)疲勞和耐臭氧性能，可耐150～170℃高溫，其耐寒性能優(yōu)于氟橡膠，耐酸性汽油是普通丁腈橡膠(NBR)的5倍多，耐磨性比普通NBR提高50%以上，熱降解溫度隨著氫化度的提高而提高，比NBR高30～40℃，其優(yōu)異的耐新型制冷劑、耐硫化氫性能更是無以倫比。因而，它作為高性能膠管、膠帶、密封和減震零部件、膠輥、特殊電線電纜等制品的材料，在高鐵、航空、新能源，錦湖內(nèi)胎用EPDM，錦湖內(nèi)胎用EPDM、汽車，錦湖內(nèi)胎用EPDM、石油等重大工業(yè)領(lǐng)域，具有其他材料無法替代的作用。比較簡(jiǎn)單有效地提高粘合力的辦法是提高溫度和壓力。錦湖內(nèi)胎用EPDM</p><div

近年來，多楔帶在汽車得到普遍應(yīng)用，而發(fā)動(dòng)機(jī)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(dá)不到要求。由于ＨＮＢＲ過于昂貴，人們?cè)谘芯堪l(fā)現(xiàn)小量的油污并不對(duì)發(fā)動(dòng)機(jī)前端的皮帶造成損害，可使用較廉價(jià)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(dòng)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(dòng)受力機(jī)理與多楔帶有很大不同，對(duì)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(bào)道實(shí)際使用壽命能達(dá)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。膠黏劑用三元乙丙膠錦湖誠信經(jīng)營過氧化物常用交聯(lián)助劑有:烯丙基化合物(TAC和TAIC等),DTDM,HVA-2等。</p><div

ＥＰＤＭ／氫化丁腈橡膠（HNBR）：中國**ＣＮｌ６２１４４１Ａ提出用乙烯含量６０％以下的ＥＰＤＭ與不超過３０份的ＨＮＢＲ并用，并配有５０份甲基丙烯酸鋅，其中ＥＰＤＭ作為海相，ＨＮＢＲ為島相的共混物，具有耐高低溫、耐油、高硬度、**度、耐疲勞性能，可用于高負(fù)荷傳動(dòng)帶。 </p> <p> ＥＰＤＭ／乙烯．醋酸乙烯共聚物（EVM）：通過與不同ＶＡ含量的ＥＶＭ橡膠的并用，以及采用不同的共混比，研究了ＥＰＤＭ與ＥＶＭ并用膠料對(duì)物理機(jī)械性能的影響。結(jié)果表明：ＥＰＤＭ與ＥＶＭ并用，可以有效改善ＥＰＤＭ膠料的耐熱性、耐油性、耐低溫性、耐溶劑性及阻燃性，粘合性能增加。同時(shí)降低了膠料的門尼粘度，并用膠具有良好的混煉工藝及成型加工性。 </p> <p> ＥＰＤＭ／ＥＶＭ并用膠以其優(yōu)良的耐熱性、低壓變性、耐油性、無鹵阻燃性廣泛應(yīng)用于以汽車工業(yè)為主的工業(yè)用、普通用各種密封制品、擠出制品、膠輥、膠帶、符合環(huán)保要求的電纜等各種橡膠制品。 </p><p> EPDM的黏合二： </p> <p> 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。乙丙橡膠有優(yōu)異的耐天候、耐臭氧、耐熱、耐酸堿、耐水蒸汽、顏色穩(wěn)定性、電性能、充油性及常溫流動(dòng)性。</p><div
