Efficient and energy-saving engine lubricating oil and preparation method thereof

Abstract

The invention provides an efficient and energy-saving engine lubricating oil and a preparation method thereof. The efficient and energy-saving engine lubricating oil comprises base oil, polyol ester synthesized oil, nanometer chromium oxide, nanometer copper oxide, ethylene-propylene-diene rubber, an antiwear agent, polyisobutylene succinimide, mineral silicon oil, dimethyl silicon oil, polyisobutene and sulfurized calcium alkyl phenolate. Due to reasonable ratio and combination of all the components in the technical scheme, the efficient and energy-saving engine lubricating oil has a good energy-saving effect, the life of an engine can be prolonged, the problem that wear and oil consumption of an automobile are abnormally increased under high temperature and high load can be solved, and the formed oil sludge and carbon deposition of the engine can be reduced; and the efficient and energy-saving engine lubricating oil has good friction characteristics, excellent mechanical stability aswell as extremely good heat stability and oxidation stability and is capable of reducing heat and wear and reducing the oil consumption.

Description

technical field [0001] The invention belongs to the technical field of energy saving, and in particular relates to a high-efficiency energy-saving engine lubricating oil and a preparation method thereof. Background technique [0002] "Lubrication" is a traditional equipment management technology. With the development of modern equipment to large-scale, precision and automation, there are higher requirements for the traditional technology of "lubrication", which is mainly reflected in how to adopt advanced lubrication technology and deployment methods , Reduce abnormal wear of equipment, reduce spare parts consumption, reduce energy loss, and ensure safe operation of equipment. The existing large-scale heavy-duty vehicles have a large operating load, high summer temperature, and large wear and tear, which have a great impact on the life of the vehicle. Therefore, a lubricant is provided to solve the problem that the heavy-duty vehicles can be better under the environment of h...
