近年來，多楔帶在汽車得到普遍應(yīng)用，而發(fā)動機(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，人們在研究發(fā)現(xiàn)小量的油污并不對發(fā)動機(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，錦湖KUMHO過氧硫化EPDM，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(jī)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），錦湖KUMHO過氧硫化EPDM，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，錦湖KUMHO過氧硫化EPDM，尤其是耐高低溫性能，可在-５５~１２０℃正常使用，做到全天候使用。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過氧硫化EPDM</p><div

在拉斷強(qiáng)度降低幅度比較大的并用比時（ＥＰＤＭ／ＮＲ＝７５／２５）碘值與拉斷強(qiáng)度的關(guān)系。拉斷強(qiáng)度隨碘值增大而直線上升，這說明通過提高碘值可以改善并用膠的共硫化性，至于第三單體的效果，在同一碘值下進(jìn)行的比較表明，硫化速度快的乙叉降冰片烯ＥＰＤＭ膠共硫化性遠(yuǎn)為優(yōu)越，但決定的因素還是碘值。其次，調(diào)節(jié)硫化的特性也是有力的措施，并用膠的拉斷強(qiáng)度隨硫化促進(jìn)劑種類的不同而有明顯的差異，采用低速促進(jìn)劑時的拉斷強(qiáng)度比采用超速促進(jìn)劑高得多，硫化速度（Ｖ）和硫化速度常數(shù)（Ｋ）與高不飽和橡膠的相應(yīng)值越接近越好。 </p> <p> 炭黑的影響如下：補(bǔ)強(qiáng)性越大，則拉斷強(qiáng)度越高，不同摻和方法的并用膠物理性能不同中兩種方法：一種為生膠摻和法，即先將生膠相互摻和，然后再加配合劑。另一種為母煉膠摻和法：系兩種生膠先分別加配合劑，***將兩種膠料摻和，性能以后者為佳。 </p> <p> <br />

8.輪胎用EPDM選擇胎側(cè)：輪胎胎側(cè)是輪胎側(cè)向變形比較大的部位,又與大氣直接接觸,要求膠料的耐屈撓性能、耐臭氧性能和耐天候老化性能良好。在胎側(cè)膠配方中添加少量防護(hù)蠟可對輪胎胎側(cè)起靜態(tài)防護(hù)作用,但在動態(tài)條件下防護(hù)作用**減弱,輪胎在使用一段時間后胎側(cè)仍會出現(xiàn)大量龜裂。EPDM具有突出的耐臭氧性能、耐天候性能和耐熱性能，并用少量的EPDM可以***提高胎側(cè)的耐臭氧、耐候性能和耐裂口增長性能。推薦牌號：錦湖KEP5560推薦理由：窄分子量分布，超高的ENB含量，硫化速度快，用于輪胎制品時能夠很好的與NR、SBR等二烯類橡膠共混，保證良好的物理性能內(nèi)胎：因具有良好的氣密性能和耐熱性能而在輪胎內(nèi)胎中得到廣泛應(yīng)用"但其加工性能較差存在膠料收縮大&滯后生熱大和加油后易粘輥等問題并且老化時分子鏈傾向于斷裂導(dǎo)致使用后期膠料發(fā)粘嚴(yán)重時造成內(nèi)外胎粘在一起。

此概念的基礎(chǔ)上采取添加所需材料的方法。追求“簡單的就是比較好的"這排除計(jì)量失誤發(fā)生的可能性，材料的種類是越少越好。為便于在場進(jìn)行原材料管理，以由于近來各材料生產(chǎn)商都在不斷地開發(fā)新材料，村料也就在所難免。因此使用橡膠產(chǎn)品要求性能上年然而，在不能準(zhǔn)確把任何時候添加材料，都可能成為泄漏、起霜等負(fù)面因素。把握村料效果的情況下，比較好不要盲目地河地添加材料。 </p> <p> 漫合設(shè)計(jì)時適宜的材料種類 </p> <p> 聚合體3種以下 </p> <p> 碳/黑 2種以下 </p> <p> 填充物 2種以下 </p> <p> 軟化劑可塑劑 2種以下 </p> <p> 加工助劑 2種以下 </p> <p> 抗老化劑 2種以下 </p> <p> 促進(jìn)劑(丁晴橡膠混合) 3種以下 </p> <p> 促進(jìn)劑(三元乙丙橡膠般混合) 4種以下 </p> <p> b.關(guān)于材料的添加量 </p> <p> “比較低添加量比較好為0.2phr以上”其理由在于，在現(xiàn)場使用大型機(jī)械進(jìn)行混煉操作時，經(jīng)常發(fā)生分散不充分的情況并且如添加量少，將會發(fā)生分散不均勻的現(xiàn)象。 </p> <p> 如果不得已要添加0.1phr以下的量時，需要事先完全與材料混合，使?jié)舛冉档?，此外，氧化鋅的比重為5.6左右時，雖然重量份數(shù)為5Phr.但容量份數(shù)為0.891通常添加量不需要5Phr,比較好是添加3Phr以上，在進(jìn)行硫化過程中，當(dāng)內(nèi)模被行財(cái)，可以考慮混合少量的氧化鋅，但這時比較好添加活性氧化鋅活性氧化鋅)。 EPDM與NBR分子極性差別很大，相容性很差，共混時需要添加相容劑提高二者的相容性。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="錦湖KUMHO過氧硫化EPDM,錦湖"
