Abstract

L'invention concerne un mélange d'additifs utilisé comme constituant d'une formulation à base d'huile minérale, en tant que constituant principal, et de proportions réduites d'un mélange d'additifs. Ledit mélange d'additifs contient les constituants suivants : a) des copolymères éthylène-vinylester modifiés par des groupes polaires, présentant des indices rectifiés de masse polaire de l'ordre de 3.000 à 50.000 et une proportion en éthylène comprise entre 50 et 90 % en masse, et b) des acides monocarboxyliques C12-C40 pontés par oxyalkyle C2-C6, et/ou c) des copolymères partiellement et/ou entièrement imidisés, à base d'anhydrides d'acide dicarboxylique C4-C20 insaturés et de vinylaromatiques et/ou d' alpha -oléfines C2-C36, la teneur du mélange d'additifs dans l'huile minérale se situant entre 0,005 et 1 % en masse. Ces formulations s'utilisent comme milieux coulants à transporter à basse température et comme carburant à base d'huile minérale à haut pouvoir lubrifiant et à aptitude élevée à l'écoulement.
