ADDITIVE MIXTURE AS COMPONENT OF A MINERAL OIL COMPOSITION

摘要

An additive mixture as component of a mineral oil composition comprises, as main components and trace proportions of the additive mixture, the following additive components: a) ethylene vinyl ester copolymers modified with polar groups with molecular mass weight averages of 3,000 to 50,000 and an ethylene component of 50 to 90 mass %, b) C12-C40 monocarboxylic acids with C2-C6 oxyalkyl bridges and/or c) partly and/or completely imidated copolymers of unsaturated C4-C20 dicarboxylic anhydrides and vinyl aromatics and/or C2-C36 alpha -olefins, whereby the content of the additive mixture in the mineral oil is 0.005 to 1 mass %. The compositions are suitable for low temperature flowing media and high lubricity mineral oil fuels of high ease of flow.
