More Information
Summary:Disclosed is a lubricant composition, particularly a grease composition and a lubricating oil composition which are obtained by blending an aralkylated diphenylamine and a phenol compound having a molecular weight of not less than 340 into a base oil. Such a lubricant composition is hardly decomposed or volatilized even at high temperatures and has a long oxidation life. The lubricating characteristics of this lubricant composition can be maintained for a long time. L'invention concerne une composition lubrifiante, notamment une composition de graisse et une composition d'huile lubrifiante obtenues par mélange d'une diphénylamine aralkylée et d'un composé de phénol ayant un poids moléculaire d'au moins 340 dans une huile de base. Une telle composition lubrifiante ne se décompose ou ne se volatilise presque pas, même à des températures élevées, et présente une durée d'oxydation longue. Les propriétés lubrifiantes de cette composition lubrifiante peuvent être conservées pendant une longue durée.
