Abstract

The invention discloses green environment-friendly lubricating oil for a diamond-like film friction pair. The green environment-friendly lubricating oil for the diamond-like film friction pair includes, by weight ratio, 80-85 parts of hydroisomerization dewaxing base oil, 1-2 parts of acrylic acid and ether copolymer, 1-2 parts of polymethacrylate, 2-4 parts of monoalkenyl succinimide, 1-2 parts of oleic acid gylcol ester, 2-3 parts of 4, 4'-Methylenebis (2,6-di-tert-butylphenol), 2-4 parts of viscosity index improver OCP (ethylene / propylene copolymer), 1-2 parts of alkenyl succinate, and 3-5parts of oleic acid oleylamine modified nano-ruthenium particles. The green environment-friendly lubricating oil for the diamond-like film friction pair has the advantages of forming a lubricating film on the surface of the metal and DLC (diamond-like carbon) carbon film at the same time with green low-melting-point metal bismuth that is recognized as harmless to the human body used as a nano-additive core and a sulfur-free phosphorus modifier used for modification, and significantly improving stability and anti-friction and anti-wear ability of the DLC friction pair.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a green and environment-friendly lubricating oil used for diamond-like carbon film (DLC) friction pairs and a preparation method thereof. Background technique [0002] Diamond-like carbon film (DLC) is a kind of amorphous carbon film with high hardness, low friction coefficient, high wear resistance and high chemical stability. As the third-generation solid lubrication technology, it has broad application prospects in the future automotive and aerospace fields. The low friction coefficient of DLC film can effectively reduce the friction loss of key parts of the engine, and it is the focus of research in the field of engine energy saving and emission reduction in the world. However, the lubricating oil friction reducers, antiwear agents, and extreme pressure agents widely used in these fields are designed and synthesized based on the surface reaction with meta...
