中间相沥青中间相沥青mesophase pitch zhongjianx通ng liqing中间相沥青(mes叩hase Pitch)经热处理后含相当数量中间相的沥青。在常温下中间相沥青为黑色无定形固体。中间相沥青中的中间相组分具有光学各向异性的特征。中间相在形成初期呈小球状,称中间相小球体。小球体大小不一,大的可达50印m以上,初生的仅有百分之几以m。中间相沥青的分子量比其母相(原料)沥青高4一5倍,其中80%以上的分子量超过4000。中间相沥青的密度为1.4一1.59/c m3。 1964年,澳大利亚人布鲁克(J .D.Brooks)和泰勒(G .H.Ta刃or)发现沥青在加热过程中生成小球体,并逐渐长大、融并,最后成为中间相体。他们首次使用了中间相这一术语。(见中间相成焦机理) 中间相沥青的软化点和粘度,都随中间相含量的增加而提高。如中间相含量为57%的中间相沥青,其软化点为288℃,当中间相含量增加到80%以上时,其软化点为345C。中间相沥青的粘度又与温度有密切关系,含中间相40%的沥青在250℃时的粘度为ZoPa·s,在300’C时为IPa·s;而含70%的中间相沥青要有上述两个粘度,温度应分别为390亡和4切℃。 中间相沥青的制备过程一般包括沥青热溶、过滤、减压蒸馏和热缩聚等工序。(见图) 沥青十溶剂(啼琳或毗陡或蕙油等) 沥青:溶剂1:2一3 丫 热济、搅拌、过滤 { 专寺 滤渣滤液 (游离炭、 炭黑等) 减压蒸馏 否马 回收溶剂精制沥青 备 热缩聚温度320~J50℃,2 一60卜,通N:搅拌 中问杆于沥青 :f~一手壬,兰一叮习潜在中间相沥青是中间相沥青经加氢处理,沥青由各向异性转变为各向同性后再经热处理得到的一种沥青。这种沥青在室温下呈各向同性,在加热或外力作用下仍可全部变为各向异性。潜在中间相沥青的熔融温度比中间相沥青低(可降到300℃以下),从而具有更好的加工性能。 预中间相沥青是原料沥青经加氢处理、过滤和蒸馏再经热处理得到的一种各向同性沥青,其软化点在300℃以下,均为唆琳可溶物。用它纺丝得到的沥青纤维,在氧化、炭化过程的前期又全部转变为各向异性的中间相沥青。中间相沥青主要用于制备中间相沥青炭纤维,还可用于制造针状焦,以及碳一碳复合材料用的基体材料和提取中间相碳微珠等。利用中间相沥青制得的沥青炭纤维,其最高的抗拉弹性模量已接近石墨晶须的理论值(1 03OGPa),因此它是一种新材料,有着广阔的发展前景。可以预料,到21世纪中间相沥青的生产将会有很大的发展。 (李志龙黄宁明)
