Abstract

The invention discloses a lubricating oil, comprising the following materials: on a weight basis, 0.01-0.5 parts of paraffin, 0.0-1.0 part of oxymolybdenum dialkydithiophosphate, 0.1-1 part of polyurethane, 0.02-1.25 parts of modified polyurea, 3-5 parts of polyethylene wax, 1-50 parts of zinc butyl octyl dithiophosphate, 20-67 parts of petroleum ether, 1-20 parts of anhydrous ethanol, 3-15 parts of xylene, 3-56 parts of dichloromethane, 1-20 parts of benzyl alcohol, and 3-12 parts of n-pentane. When the lubricating oil is used at high temperature, viscosity index is high, and viscosity temperature characteristics are good. The lubricating oil is excellent in oil consumption reduction property, can maintain high temperature high shear (HTHS) viscosity at 150 DEG C and improve oil consumption reduction property at the same time, especially can reduce the HTHS viscosity of the lubricating oil at 100 DEG C, and improve mini rotary viscosity (MRV) at -40 DEG C, and can obtain unexpected beneficial effects.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to a lubricating oil. Background technique [0002] Mechanical lubricating oil refers to the oily liquid applied to the surface of moving parts such as machine bearings or certain parts of the human body. It has the functions of reducing friction, avoiding heat, preventing machine wear and medical purposes. It is generally the product of fractionated petroleum, but also extracted from animal and vegetable oils. Also known as "grease". Non-volatile oily lubricant. According to its source, it can be divided into three categories: moving oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil. The amount of petroleum lubricating oil accounts for more than 97% of the total amount, so lubricating oil often refers to petroleum lubricating oil. It is mainly used to reduce the friction between the surfaces of moving parts, and at the same time, it has the fu...
