采用2HNMR和IR,表征了油酸/三乙醇胺/液体石蜡/水体系层状液晶的结构,并以该体系为润滑剂,测定了其在铝合金表面的磨痕宽度和摩擦系数,同时与液体石蜡和商用润滑剂12-羟基硬脂酸锂进行了比较.结果表明,OLA/TEA/LP/H2O体系层状液晶具有较好的极压性能,对于铝合金材料是一种较好的润滑剂.

The tribological properties of lamellar liquid crystal ofOLA/TEA/LP/H2O system used as a lubricant for aluminum alloy surface was investigated.The structure of lamellar liquid crystal was characterized by 2H NMR and IR techniques. The experiments on the wear scar width and vertical load showed that the lamellar liquid crystal exhibited a higher load carrying capacity than paraffin oil and commercial lithium grease, indicating the lamellar liquid crystal of OLA/TEA/LP/H2O system could be a good lubricant for aluminum alloy.
