Nanometer dual-fuel lubricating oil and preparation method thereof

Abstract

The invention relates to nanometer dual-fuel lubricating oil comprising the following mixed components in percentage by weight: 95.6% of base oil, 1% of composite special nanometer ceramic anti-wear agent, 1.2% of high-base number synthetic calcium sulfonate T-106, 0.7% of dual succinimide ashless dispersant T-154, 1.4% of sulfur phosphorous butyloctyl zinc salt T-202 and 0.1% of non-silicon composite anti-foaming agent 2#. The nanometer dual-fuel lubricating oil disclosed by the invention has the advantages of effectively reducing the abrasion of a motor, prolonging the service life of the motor, remarkably improving the fuel efficiency, reducing the fuel consumption, obviously reducing the exhaust gas emission, reducing the air pollution, protecting the environment, effectively improving the working environment of the motor, improving the acceleration performance, increasing the power, obviously reducing the temperature of the motor, reducing the equilibrium temperature of parts and the lubricating oil to about 75 DEG and eliminating the mechanical thermal expansion phenomenon, having excellent cleaning dispersing performance and effectively controlling the generation of oil sludge carbon deposit to ensure that the oil products are not easy to age.

Description

Technical field: [0001] The invention belongs to the technical field of engine lubricating oil, in particular to a nanometer dual-fuel lubricating oil and a preparation method thereof. Background technique: [0002] The car is an important tool in people's daily life, and the most important part is the engine, which provides abundant power for the car, but the normal operation of the engine is inseparable from good lubrication, especially the high-speed moving parts in the cylinder, the traditional The main performance indicators of lubricating oil used in fuel engines include viscosity, viscosity temperature, thermal oxidation stability, cleaning and dispersibility, corrosion resistance, total base number and total acid number, flash point and ignition point, etc. Bad, reflecting the quality level of the lubricating oil.

Problems solved by technology

[0003] With the increasing price of fuel, some cars are gradually using liquefied petroleum gas and natural gas as new fuels. These gases can continue to use fuel engines, and only need simple modification. However, the high temperature generated by the gas during combustion will make ordinary Too fast oxidation of lubricating oil will lead to the decline or failure of lubricating oil quality, which is not conducive to the lubrication protection of the engine. The high-ash additives of ordinary lubricating oil are very easy to form hard deposits on the surface of engine components

Due to the valve wear and lax closure caused by the dry gas, the exhaust gas after combustion will contain a large amount of nitrates, which will lead to the nitration of ordinary lubricating oil, and generate a large amount of sludge, blocking the oil circuit or forming harmful substances such as paint film, causing Crashing, deflagration, abnormal engine noise, power drop, etc.
