id="kt732h4" class="box"><p><p style="text-indent:25px">NBR的溶液加氫法是在NBR溶液中,用氫氣進行加氫。NBR分子鏈上的丙烯睛含量決定了它的耐油性,氫化NBR時,只對二烯單元的雙鍵選擇性加氫還原成飽和鍵,并不氫化丙烯腈單元的側(cè)鏈睛基—C≡N。目前這種加氫法主要選用兩種催化劑,即非均相載體催化劑和均相配位催化劑。首先問世的非均相載體催化劑是以碳為載體的Pd/C催化劑,這種催化劑的選擇性高，HNBR空調(diào)油封氫化丁氫,氫化率比較高達95.6%,但在加氫反應中,與炭黑親合的二烯橡膠易吸附在炭黑表面,攪拌時炭黑易凝聚成塊,存在于HNBR中,對其硫化特性會產(chǎn)生不良影響。日本瑞翁公司選用SiO2為載體的Pd/SiO2催化劑,已實現(xiàn)了工業(yè)化。這兩種載體催化劑氫化NBR時，HNBR空調(diào)油封氫化丁氫,NBR催化劑殘留物或聚合反應中使用的助劑可能粘附于載體表面或滯留在微孔內(nèi),使催化劑活性急劇下降,影響再次使用，HNBR空調(diào)油封氫化丁氫。詹博特?氫化丁腈橡膠(Zhanber? HNBR)已有11個通用牌號、9個特殊牌號的產(chǎn)品上市，滿足了市場應用的需求。HNBR空調(diào)油封氫化丁氫</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="HNBR空調(diào)油封氫化丁氫,贊南" src="http://tyunfile.71360.com/UpLoadFile/junyi/2019/9/637038073973900632/6370380739739006326312711.jpg"></div><p> 其它用途，HNBR還可用作擋泥板，振動吸收材料，纜索等。HNBR膠乳可用作表面涂層，用作紙張，皮革、陶瓷、纖維的粘合劑以及發(fā)泡橡膠，浸漬膠乳產(chǎn)品。HNBR還可作ABS/PVC共混體系的相容劑，在ABS/PVC共混物中添加HNBR，其拉伸強度性能優(yōu)異。將PVC/EVA與HNBR共混，可改善PVC/EVA的韌性。將HNBR用作塑料添加劑，可提高塑料的抗沖擊性能、耐老化和耐油性能，如PVC/HNBR具有很高的耐熱空氣老化性能和在燃油中的耐熱老化性能；HNBR/PC強度高，加工性能好，并具有良好的熱穩(wěn)定性；EPDM加入HNBR后可大幅度提高耐油性能，這些共混改性技術給HNBR的應用開辟了新的領域。 </p> <p> 氫化丁腈橡膠是近二十年發(fā)展起來的綜合性能優(yōu)異的耐油、耐熱橡膠，在汽車、油田密封等方面都得到了***的應用。由于HNBR生產(chǎn)工藝復雜，價格昂貴，在一定程度上限制了其在國內(nèi)工業(yè)領域中的推廣應用，研制新型生產(chǎn)工藝路線，降低生產(chǎn)成本，或根據(jù)性能與價格綜合因素，開發(fā)高性能HNBR共混改性材料，是HNBR應用的研究方向。 HNBR空調(diào)油封氫化丁氫近幾年，在一些新機型上也大量使用了一些特種橡膠（包括HNBR）。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="HNBR空調(diào)油封氫化丁氫,贊南" src="http://tyunfile.71360.com/UploadFile/junyi/637206634852353515/9626937.jpg"></div><p> 補強體系：HNBR可以用炭黑、白炭黑、陶土、CaCO3來提高混煉膠的機械性能。炭黑補果大小依次為：高耐麿＞快壓出＞半補強和噴霧炭黑，而填充噴霧炭黑的膠料壓縮長久變形小，Zeon公司開發(fā)的ZSC復合材料，其拉伸強度高達60MPa，并具有較高的定伸力、撕裂強度和良好的加工性能，但壓縮長久變形有所增大，當該混煉膠硫化時，ZnO/MMA發(fā)生聚合反應，并與HNBR接技，形成尺寸為20～30nm聚甲基丙烯酸鋅鹽離子簇，是一種新型橡膠增強納米復合材料。 </p> <p> 增塑體系：HNBR常用于高溫，燃油及其它苛刻環(huán)境中，要求所用的增塑劑必須是難揮發(fā)，耐抽出。常用的增塑劑品種有Thiokol TP－95（已二酸二（丁氧基乙氧基乙）酯），Ｇ8205（分子量為1000～2000的聚酯），AdiksizerＣ－9Ｎ，Ｃ－8（偏苯三酸酯類）等。合適的增塑劑可以降低HNBR硫化膠的玻璃化溫度，同時提高耐油性和未硫化膠的加工性能。由于HNBR主要用于各種燃油和腐蝕性介質(zhì)的惡劣環(huán)境中，工作溫度在40～150℃之間，所選擇的增塑劑必須具有高沸點、耐抽出的性能。為避免噴霜，增塑劑用量應低于其比較大吸收量。HNBR經(jīng)150℃×160h熱空氣老化試驗表明，用TOTM（三辛基偏苯三酸酯）和TINTM（三異壬基偏苯三酸酯）作增塑劑，硫化膠的耐熱性比較好 </p><p> 早在21世紀初期，全球HNBR已在NBR市場中占有5～10%的份額，保守地估計HNBR在國內(nèi)的市場用量約為1.5萬噸左右，可見HNBR的市場地位日趨重要。由于生產(chǎn)HNBR使用的催化劑價格昂貴、關鍵生產(chǎn)技術難度大，目前在世界范圍內(nèi)，產(chǎn)品上市的只有瑞翁（ZEON）公司、阿朗新科（ARLANXEO）公司和贊南科技（上海）有限公司（Zannan Scitech Co.,Ltd.）, 總產(chǎn)能大約為2.5~3萬噸/年。市場上的HNBR產(chǎn)品主要來自于上述三家公司公司，值得關注的是國產(chǎn)HNBR—詹博特®氫化丁腈橡膠（Zhanber ® HNBR）異軍突起，順利地進入了在國內(nèi)外的HNBR市場上，獲得了市場的認可。 </p> <p> 全球氫化丁腈橡膠生產(chǎn)現(xiàn)狀，從HNBR的工業(yè)化生產(chǎn)發(fā)展歷程來看，HNBR生產(chǎn)技術的優(yōu)勢主要就體現(xiàn)在其生產(chǎn)過程所用催化劑體系，即：催化加氫活性和選擇性、催化劑回收、產(chǎn)品后處理等關鍵技術的先進性上。上世紀九十年代，全世界可工業(yè)化生產(chǎn)HNBR的廠家為德國拜耳（Bayer）公司、日本瑞翁 (Zeon)公司和加拿大寶蘭山（Polysar）公司等三家公司，他們都是在解決了催化加氫、催化劑回收以及產(chǎn)品后處理等關鍵工藝技術問題后，才實現(xiàn)了工業(yè)化生產(chǎn)的，當時全球的HNBR產(chǎn)能和產(chǎn)量基本上在1萬噸/年左右。氫化丁腈橡膠其優(yōu)異的耐新型制冷劑、耐硫化氫性能更是無以倫比。</p><div

HNBR是由丁腈橡膠進行特殊加氫處理而得到的一種高度飽和的彈性體。氫化丁腈橡膠具有良好耐油性能（對燃料油、潤滑油、芳香系溶劑耐抗性良好）；并且由于其高度飽和的結(jié)構(gòu)，使其具良好的耐熱性能，優(yōu)良的耐化學腐蝕性能（對氟利昂、酸、堿的具有良好的抗耐性），優(yōu)異的耐臭氧性能，較高的抗壓縮變形性能；同時氫化丁腈橡膠還具有**度，高撕裂性能、耐磨性能優(yōu)異等特點，是綜合性能極為出色的橡膠之一。

style="text-indent:25px">33、當氫化丁腈橡膠剩余雙鍵含量＜1％，只能采用過氧化物硫化，殘余雙鍵＞5％時，可采用過氧化物或硫黃硫化。采用過氧化物硫化比用含硫化合物硫化有更好的耐熱性和較低的壓縮長久變形。常用的過氧化物硫化劑為Vul－cup40KE、PeroximonF－40，硫化促進劑HAV－2、TAIC、TMPT可提高硫化效率，避免發(fā)生焦燒。國內(nèi)多采用DCP（過氧化二異丙苯）或BDPMH（2，5－二甲基－2，5（二叔丁過氧基）已烷）作硫化劑，當BDPMH用量為4～7份，促進劑TAIC用量為4份時，硫化膠的壓縮長久變形率可低于20％。對于雙鍵含量較高的HNBR，采用低硫高促硫化體系，也可獲得具有較高耐熱性和良好力學性能的硫化膠。為了進一步提高HNBR在高溫下的耐熱老化性能，配方中常使用防老劑并用，如：RD/MB或MB/二苯胺類防老劑445。適當加入金屬氧化物，可進一步提高硫化膠的耐介質(zhì)腐蝕性能。HNBR空調(diào)油封氫化丁氫</p><p
