Abstract

The invention discloses lubricating oil comprising the following substances, by weight: 0.01-0.5 parts of paraffin wax, 0.0-1.0 parts of oxymolybdenum dialkydithiophosphate, 0.1 parts of a terpolymer, 0.02-1.25 parts of modified polyurea, 3-5 parts of low-molecular-weight polyethylene wax, 1-50 parts of zinc butyloctyl 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, 3-12 parts of n-pentane, and 40-80 parts of base oil. When the lubricating oil provided by the invention is applied under a relatively high temperature, the lubricating oil has high viscosity index and good viscosity-temperature characteristics. The lubricating oil has an excellent oil-consumption-saving characteristic. With the lubricating oil, high-temperature high-shear viscosity under a temperature of 150 DEG C can be maintained while the oil-consumption-saving performance can be improved. Especially, the 100 DEG C HTHS viscosity of the lubricating oil can be reduced, and the MRV viscosity under a temperature of -40 DEG C can be improved. According to the invention, an outstanding beneficial effect can be obtained.

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...
