蓖麻油酸咪唑啉硼酸酯的合成与摩擦学性能研究

Synthesis and Friction property of a castor oil acid imidazoline borate

以蓖麻油为原料 ,合成咪唑啉硼酸酯 ,用NMR仪测定产品结构 ,在40kg负载下 ,四球机测试 ,0.7%的咪唑啉硼酸酯对钢球磨痕直径为0.568mm。

An imidazoline borate was obtained by reacting castor oil with N-(α-hydroxyethyl) ethylene diamine and then the product of which reacting with boric acid. The structure of the final product was determined by NMR. The friction properties about the product were tested on a four-ball machine under 40kg. The measuring result stated that 0.7% product had smaller wear sear diameter (0.568mm).
