摘　　要：提出对锂基润滑脂的快速溶解方法是锂基润滑脂中皂基稠化剂的位于外部的烃基端第一次溶解,随后对皂基稠化剂的位于内部的羧基端进行第二次溶解。结果表明:有机溶剂溶解锂基润滑脂外部的烃基端,再加入不同比例的乙酸能快速溶解锂基润滑脂内部的羧基端,该方法简便、快速、实用、高效,不仅可以提高锂基润滑脂的溶解速度,提升样品的前处理效率,而且还能减少强酸的使用,从而减少检测设备的腐蚀,减少有毒气体和酸污染的情况。It is proposed that the quick dissolving method of lithium grease is to dissolve the alkyl end of soap thickener in lithium grease at the outside for the first time, and then dissolve the carboxyl end of soap thickener at the inside for the second time. The results show that organic solvent can dissolve the hydrocarbon end of lithium grease,and then acetic acid with different proportions can quickly dissolve the carboxyl end of lithium grease. This method is simple, fast, practical and efficient, which can not only improve the dissolution rate of lithium grease and improve the efficiency of sample pretreatment, but also reduce the use of strong acid, thus reducing the corrosion of testing equipment and toxic gas and acid pollution.
