| 摘 要： | 以γ-甲基丙烯酰氧基丙基三甲氧基硅烷（硅烷偶联剂KH570）为改性剂，对纳米SiO2进行表面改性，并利用紫外可见分光光度计测定其在油中的稳定性，用四球试验和止推圈试验考察改性后纳米SiO2的抗磨减磨性能，结果表明，用KH570改性后的纳米SiO2在20#润滑油中有很好的分散稳定性，将其添加到润滑油中进行摩擦磨损实验，证明，摩擦系数最多可降低约45％，磨损量明显减少，并出现负磨损现象。其作为润滑油添加剂能有效提高油品的抗磨减磨性能。

| Abstract: | The nano-SiO2 was modifided with KH570,and the dispersion stabilization performance were measured by ul- traviolet visible spectroscopical luminometer. The anti-weare and anti- friction performance were measured by four ball and stop thrust ring tests. The results show nano-SiO2 improved by KH570 has good dispersion stability in 20# lubri- cants. The friction and wear experiment that added modified nano-SiO2 into the lubricants show that friction coefficient can reduce about 45%, the wear amount can reduce obviously and appear negative wear phenomenon. Let it to he lubricants additives can improve the anti-friction effectively |
