Problems solved by technology

Due to the wide geographical distribution of our country, the temperature difference in different regions is very large. Due to the drastic temperature change, the fluidity of the lubricating oil at low temperature is insufficient, and the lubricating oil is obviously thinner at high temperature, and the thickness of the oil film is insufficient, resulting in a decrease in lubricating performance and poor startability at low temperature. , pulling cylinders and other issues

Abstract

The invention discloses novel wide-temperature-range lubricating oil and a preparation method thereof. The lubricating oil is prepared from, by mass, 75-98 parts of base oil, 0.8-3.5 parts of a lubricant, 0.05-0.8 part of N-(2,3-dichloro-6-amino-benzyl)glycine ethyl ester, 0.05-2.5 parts of triethanolamine, 0.5-2.0 parts of sodium benzoate and 0.05-0.2 part of chlorobenzene. The lubricating oil has advantages of wide utilization temperature range, high flashing point, high kinematic viscosity, small trail diameter, excellent lubricating performances and high abrasion resistance under a high-load condition.

Description

technical field [0001] The invention belongs to the field of lubricants, and in particular relates to a wide-temperature range lubricating oil with a wide use temperature range and a preparation method thereof. Background technique [0002] Lubricating oil is an indispensable substance in the mechanical field. It mainly plays the role of reducing friction, increasing mechanical operating speed and prolonging mechanical life. It is especially prominent in the automotive industry. Its tribological behavior is the main cause of automotive mechanical failure and energy consumption. Therefore, reducing the energy loss caused by the friction of engine components is an important factor to reduce the fuel consumption of automobiles. The improvement of engine design and the improvement of lubricating oil formula technology can directly improve the fuel economy of automobiles, but the cost of improving lubricating oil formula is much lower than the cost of developing new engines.
