四球试验标准为:转速1450r/min,载荷392N,时间30min。试验所用钢球按照GB/308-89制造,GCr15,二级钢球,直径12.7mm,硬度为64-66HRC。试验中,将试验用油注入容纳钢球的油杯中,使液面刚好没过钢球的表面,施加垂直载荷P为392N,测量出摩擦力矩,有公式:μ=0.233×T/P(其中μ为摩擦因数;T为摩擦力矩)计算出摩擦因数,一次用于评价本发明实施例润滑油与20#标准机械油的摩擦因数μ与磨损量。四球试验的样品为20#标准机械油、实施例(1、2、3)均值、对比例1润滑油、对比例2润滑油,试验前后对钢球和环块进行充分清洗,然后用万分之一电子天平称量试验前后钢球的磨损量,用金相显微镜测量钢球的磨斑直径,并用肉眼直接观察润滑油中是否含铁粉和油泥:
表1
磨前质量g 磨后质量g 质量磨损g 铁粉或油泥含量
聚α-烯烃基础油 15.4958 15.4926 0.0032 少量
实施例1、2、3均值 15.4766 15.4766 0.0000 不含
对比例1 15.4653 15.4640 0.0013 微量

其中:对比例1为实施例1中凹凸棒土不经过预处理;
对比例2为实施例1中纳米绢云母不经过改性处理;
由表1可以看出,聚α-烯烃基础油在392N,1450 r/min,30min磨损试验条件下有明显的磨损量,并且含有少量油泥,而本发明润滑油无磨损量,并且没有油泥;当凹凸棒土与纳米绢云母不经过处理时,磨损量增加,并有微量的油泥,因此,本发明润滑油起到了很好的抗磨减摩作用,还能消除铁粉和油泥,增强润滑效果。
