摘要
用乙醇超临界干燥技术制得纳米晶状氧化锌，将一定量的纳米氧化锌及分散剂山梨醇单硬脂酸酯加入５００ＳＮ基础油中，可提高其抗磨减摩性能及承载能力。纳米氧化锌有一最佳加入量，超过此量油品最大无卡咬负荷将减小，吸附有分散剂的纳米氧化锌通过在摩擦表面的沉积而起作用。
Nanometer crystal zinc oxide was prepared with ethanol supercritical fluid drying technique.The wear resistance and load carrying capacity of the oil were improved and friction coefficient was decreased through taking proper quantity sorbitol monostearin dispersant to add 500SN base oil.The nanometer zinc oxide has an optimum adding quantity,excessive zinc oxide can result in a decrease of maximum non-seized load of the oil.The nanometer zinc oxide in the oil took effect by its deposition on rubbing surface.
