摘　　要：考察复合磺酸钙基润滑脂抗水性能优劣的方法有4种,其中方法二主要考察复合磺酸钙基润滑脂在有大量水喷淋情况下在金属上的附着能力,这是保持润滑能力的前提,因此选用方法二考察润滑脂的原料及制备工艺对复合磺酸钙基润滑脂抗水喷雾性能的影响,得出影响复合磺酸钙基润滑脂抗水喷雾性能的几个关键因素分别为:复合磺酸钙基润滑脂的锥入度、制备复合磺酸钙基润滑脂的主要原料高碱值磺酸钙中烷基苯磺酸钙的碳链长度以及烷基苯磺酸钙含量、最高炼制温度以及添加的聚合物类型。There are four ways to investigate the water resistance of calcium sulfonate complex grease,of which No.2 method mainly examines the adhesion ability of calcium sulfonate complex grease on metals when there is a large amount of water spray,which is the premise of maintaining lubrication ability,therefore,No.2 method was selected to investigate the influence of raw materials and processing of grease on the water spray resistance.The results showed that several key factors affecting the water spray resistance of calcium sulfonate complex grease were determined as follows:coning degree of calcium sulfonate complex grease,carbon chain length and content of calcium alkyl benzene sulfonate in high base number calcium sulfonate,maximum refining temperature and added polymer type.
