Abstract
La composition d'huile lubrifiante contient une huile de base (X), un antioxydant à base de diphénylamine (A), un antioxydant à base de naphtylamine (B) et un antioxydant à base de phénol contenant du phosphore (C). L'huile de base d'huile lubrifiante (X) satisfait aux exigences (1) à (4). ∙ Exigence (1) : présenter un indice de viscosité égal ou supérieur à 120. ∙ Exigence (2) : présenter un %CP de 85 ou plus selon déterminé par analyse du cycle (procédé n-d-M). ∙ Exigence (3) : présenter une densité, à 15 °C, de 0,835 g/cm3 ou moins. ∙ Exigence (4) : présenter une viscosité cinématique, à 40 °C, de 28,8 mm2}/s ou plus. Le rapport de teneur [ (B)/ (A)] de l'antioxydant à base de naphtylamine (B) à l'antioxydant à base de diphénylamine (A) est de 2,0 ou plus en rapport massique. Le rapport de teneur [ (C)/ (B)] de l'antioxydant à base de phénol contenant du phosphore (C) à l'antioxydant à base de naphtylamine (B) est de 0,15 ou moins en rapport massique.
