该润滑油的制备方法为: 1)对蛇紋石矿粉研磨, 过 100 目筛, 用 90°C的热 水, 使用高速分散机以 3000r/min的转速对蛇紋石矿粉进行剪切分散进行 5次漂 洗, 每次漂洗时间为 lmin。 之后真空烘干, 重新研磨至粉状。 2)采用 50g的表 面活性剂油酸对预处理后的蛇紋石矿粉进行表面处理。 3 )将经表面处理后的蛇 紋石矿粉及司班 80混合后研磨。 4) 向上述步骤得到的研磨后的混合物中加入
基础油, 均质化处理, 得到不含纳米氮化硼的润滑油。
对其进行摩擦学性能测试, 所用摩擦件其主要成分为 Fe, 此外, 还含有 0.42〜0.50%的 C、0.17〜0.37%的 Si、 0.50〜0.80%的 Mn、 0.25%的 Cr、 0.30% 的 Ni以及 0.25%的 Cu。 试验条件为上试样转速 300rpm, 试验负荷 500N, 试 验温度从室温起, 实时监测摩擦过程中摩擦系数的变化, 试验时间依摩擦系数 的变化而定。 当摩擦系数稳定且不再降低时, 改用基础油继续试验 10h左右, 观察比较摩擦系数的变化情况。 图 5所示为使用该对比例所制备的润滑油与实 施例 1 所制备的润滑油在同样试验条件下摩擦系数系数变化情况对比。 可以看 到, 使用对比例所制备的润滑油在试验 55h后, 才出现摩擦系数急剧降低, 且 连续 9小时保持较低的摩擦系数状态, 之后改用基础油继续试验 llh, 摩擦系数 始终保持在 0.01以下。
结合对比例与实施例试验过程中的摩擦系数的变化情况, 可以看到, 纳米 氮化硼颗粒添加后与添加前相比, 摩擦系数出现急剧降低的时间明显提前, 可 以证实, 纳米氮化硼与蛇紋石矿粉的复合作用加快了摩擦件表面保护层的形成 时间, 从而提高保护层的自修复的速度。
