含氮硼酸酯的合成及其在菜籽油中摩擦学性能研究

Synthesis of nitrogen-containing borate and study on the tribological characteristics in rapeseed oil

合成了一种新型的含氮硼酸酯,并利用红外光谱对其主要官能团进行了鉴定.通过四球试验机考察了其在菜籽油中的摩擦学性能,并采用扫描电子显微镜观察分析钢球磨斑表面形貌.结果表明,含氮硼酸酯具有较好的极压、抗磨减摩性能,且在菜籽油中的最佳添加量为3%;含氮硼酸酯较菜籽油能明显减轻钢球表面磨损.

In this article, a kind of novel nitrogen-containing borate was synthesized and characterized by IR spectrum. The tribological characteristics of nitrogen-containing borate as additive for rapeseed oil were investigated on four ball tester. The morphologies of the worn scars were observed by means of scanning electron microscopy. The results show that the nitrogen-containing borate as additive has better load-carrying, anti-wear and friction-reducing capability and the optimum amount of addition in the rapeseed oil is 3 percent; The nitrogen-containing borate can obviously abate the abrasion of the steel balls compare with the rapeseed oil.
