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(xué)穩(wěn)定性、耐熱性、耐酸、耐堿性、耐寒性。對(duì)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(diǎn)是在室溫下粘度不好，給加工制造帶來(lái)困難。硫化時(shí)間也長(zhǎng)，為此人們研究了三元乙丙膠，即在橡膠分子側(cè)鏈中引進(jìn)不飽和鍵，所以可以用硫磺硫化，同時(shí)也便于加工。乙丙橡膠綜合物理機(jī)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(zhǎng)。目前密封條市場(chǎng)主要以三元乙丙（ EPDM ）橡膠為主，且先后被應(yīng)用到門窗、機(jī)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(jī)柜密封條、汽車密封條等產(chǎn)品。 </p><p> 乙丙膠與高不飽和膠種并用一： </p> <p> 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，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，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、橡膠、金屬粘合助劑和補(bǔ)強(qiáng)劑等作用。</p>

在拉斷強(qiáng)度降低幅度比較大的并用比時(shí)（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(shuō)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(shí)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 />
