Preparation and Tribological Behaviors of Nitrogen-containing Heterocyclic Compounds without Sulfur and Phosphorus As Oil Additive
新型无硫磷含氮杂环化合物的制备及其摩擦学特性

A new kind of nitrogen-containing heterocyclic compounds without sulfur and phosphorus,Di-(Quinazolin-4-one)-N-Methylene]-n-Dodecylamine(DQMD),was prepared.Tribological behavior of synthectic DQMD as a lubricating additive in liquid paraffin was evaluated on the four-ball tester and universal friction and wear tester.The anticorrosion property and thermal stability were also investigated.The worn steel surfaces were analyzed by means of optical microscope,scanning electron microscope and X-ray photoelectro...
