style="text-indent:25px">NBR的溶液加氫法是在NBR溶液中，以貴金屬鈀、銠等為催化劑，用氫氣進(jìn)行加氫，主要選用兩種催化劑，即均相配位催化劑和非均相載體催化劑。非均相催化劑是以鈀、鍺、釕等為活性組分，以氧化鋁、氧化硅、活性炭、炭黑、堿土金屬碳酸鹽等為載體的負(fù)載型催化劑。金屬與載體的匹配對(duì)其選擇性、活性有很大影響，載體催化劑多數(shù)是以碳為載體的Pd/C催化劑，這種催化劑的選擇性高，氫化率比較高達(dá)95.6%，但攪拌時(shí)炭黑易凝聚成塊，存在于HNBR中，對(duì)其硫化特性會(huì)產(chǎn)生不良影響。NBR催化劑殘留物或聚合反應(yīng)中使用的助劑可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。均相配位催化劑目前常見(jiàn)的有四種: 鈀催化劑、銠催化劑、銥催化劑和釕催化劑，鈀系催化劑對(duì)水和空氣穩(wěn)定，貯運(yùn)方便，可反復(fù)回收利用，但活性和選擇性差；銠系催化劑具有比較高的活性和選擇性，催化劑三(三苯基膦)氯化銠適用于NBR均相加氫制備高氫化度，可在溶液或乳液中對(duì)NBR進(jìn)行催化加氫，但銠資源稀缺，價(jià)值昂貴，大規(guī)模生產(chǎn)必須有效回收利用銠來(lái)控制生產(chǎn)成本。因此，開(kāi)發(fā)新型廉價(jià)的加氫催化劑和貴金屬催化劑的回收循環(huán)利用便成為HNBR工業(yè)化生產(chǎn)的關(guān)鍵技術(shù)。ZN35258官方授權(quán)經(jīng)銷(xiāo)贊南贊南科技主導(dǎo)氫化丁腈橡膠國(guó)家標(biāo)準(zhǔn)的編制以及橡膠工業(yè)

HNBR的制備方法主要有三種:乙烯一丙烯腈共聚法、NBR溶液加氫法和NBR乳液加氫法。丙烯腈一乙烯共聚法制備HNBR時(shí),由于共聚反應(yīng)中各單體的反應(yīng)速率差異很大(rAN=0.04,rE=0.8),比較難控制,且所行聚合物性能還不太好,此法尚處于小試研究階段. NBR的乳液加氫法是利用對(duì)甲基磺酰肼熱分解產(chǎn)生得到二酰亞胺,它是有效的加氫還原劑,1984年由WideMan***發(fā)表了用二酰亞胺作還原劑制備乳液HNBR的工藝,他發(fā)現(xiàn)NBR膠乳可在水合肼、氧氣或雙氧水等氧化劑以及銅、鐵等金屬離子引發(fā)劑的作用下直接生成HNBR。美國(guó)GoodYear橡膠輪胎公司的Parker等采用乳液加氫法制得了HNBR膠乳,其配方為(質(zhì)量份):NBR膠乳: 100g,CuSO4 5H2O: 0.008g,十二烷基***鈉: 0.15g,消泡劑,水合肼: 15.6g,H2O2: 16.66g。在反應(yīng)器中加人NBR膠乳,CuSO4·5H2O,表面活性劑,加熱至45～50℃,加入水合肼,然后在以后7h內(nèi)加完H2O2,并添加消泡劑,恒溫?cái)嚢?小時(shí)可得HNBR。由于氫化母體(對(duì)甲苯磺酰肼)價(jià)格昂貴,氫化速率慢,此法尚處于小試階段。采用硫黃硫化的HNBR膠料，其粘合性能比過(guò)氧化物硫化要高得多，膠料中的硫易與纖維或金屬材料起化學(xué)反應(yīng)。ZN35258官方授權(quán)經(jīng)銷(xiāo)贊南</p><p
