摘要
以无机铜盐为铜源,加入正己醇、span-80、tween-80,在N2气氛保护下,制得粒度可控、粒径在20-50nm的纳米铜,经SEM分析为球形,用四球摩擦试验机测试含有纳米铜润滑油的极压抗磨性能,结果表明,纳米铜粉的粒度越小,润滑油的极压抗磨性能越佳。
In nitrogen atmosphere, controlled copper particle size（20-50nm）, was prepared, taking inorganic copper salt as the copper source and adding hexanol, span-80, tween-80. Nano-copper was spherically analyzed by SEM. The four ball friction equipment investigated EP and AW properties of the lubricating oil containing nano-copper, the results showed that the better EP and AW properties of the lubricating oil were obtained with smaller nano-copper particles.
