摘要
测定了月桂酸二乙醇胺（ＤＣＤ）／正丁醇（Ｃ４Ｈ９ＯＨ）／石腊油（ＬＰ）／水体系的相图．在液晶区选取两个样品点，用２ＨＮＭＲ技术和偏振光显微镜测定了这两样品点的微相结构．把液晶涂在铝合金表面测定不同负荷量下的磨痕宽度，并与十二羟基锂基脂等体系进行比较．结果表明，层状液晶在铝合金表面平行方向上的摩擦阻力较小，而在垂直方向上的负荷量高。
The phase diagram of the system of dodecyl carboxylic diethanolamine (DCD)/nbutanol (C4H9OH)/paraffin oil(LP)/water has been investigated. The phase structures of two points chosen from the liquid crystal phase region were determined by 2H NMR spectroscopy and polarizedlight microscope. The wear scar widths and the vertical loads of the two samples on the surface of aluminium alloy were measured and compared with those of water, paraffin oil, nbutanol, paraffin oil+2%nbutanol, paraffin oil+2%diethanolamine and lithium grease. The results indicate that the frictional force of the lamellar liquid crystal in the direction parallel to the surface of the alloy aluminium is very small, and the lamellar liquid crystal appear to be a good lubricant.
