在兩種橡膠并用時(shí)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，錦湖海綿制品用三元乙丙膠，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(shí)，分散狀態(tài)為微觀不均勻分散，與硫化體系無(wú)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(gè)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(shí)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(shí)強(qiáng)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，錦湖海綿制品用三元乙丙膠，研究一下如何提高ＥＰＤＭ含量大的膠料的強(qiáng)度是有意義的。不飽和羧酸金屬鹽也是一種能夠參與硫化的多功能助劑,可起硫化助劑，錦湖海綿制品用三元乙丙膠、橡膠、金屬粘合助劑和補(bǔ)強(qiáng)劑等作用。錦湖海綿制品用三元乙丙膠</p>

8.EPDM粘貼成型EPDM缺少活性基團(tuán)，內(nèi)聚能低，分子鏈段擴(kuò)散性極小，加上膠料容易噴霜，給粘貼成型工藝，尤其是制造多層結(jié)構(gòu)的制品如輪胎胎側(cè)、輸送帶、屋頂材料、膠輥、襯里等帶來(lái)較大的困難。一般可以采?。?）保持需粘合表面新鮮不被污染或用化學(xué)溶液或溶劑處理需粘合的表面；2）在需粘合的表面涂膠粘劑；3）提高粘合部位的溫度、壓力和平整度；4）與其它含活性基團(tuán)的高聚物并用；5）在膠料中加5~10份增粘劑；6）適當(dāng)提高增塑劑的用量；7）采用中間層膠或涂膠液等辦法來(lái)提高粘合力。其中比較簡(jiǎn)單有效地提高粘合力的辦法是提高溫度和壓力。非反應(yīng)性烷基酚醛樹脂增粘效果較好，但同時(shí)也使硫化膠物理機(jī)械性能下降，如彈性下降，長(zhǎng)久變形增大，硫化速度減慢。提高三元乙丙橡膠的粘合力除加增粘劑外，還可在膠料中加由膠粘劑RE、膠黏劑A和白炭黑或膠黏劑RH、膠黏劑A和白炭黑組成的粘合體系，其中白炭黑要選用沉淀法活性白炭黑。此法的缺點(diǎn)是價(jià)格較高。 KEP-2372錦湖誠(chéng)信經(jīng)營(yíng)乙丙橡膠的**主要缺點(diǎn)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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
