Abstract

The invention discloses a wide-temperature-range biolubricant for a vehicle and a preparation method of the wide-temperature-range biolubricant. The biolubricant comprises components in parts by mass as follows: 92-99 parts of base oil, 0.5-3 parts of a lubricating agent, 0.01-0.2 parts of an antioxidant, 0.3-2 parts of a pour point depressant, 0.1-5 parts of a viscosity index improver and 0.08-3 parts of a dispersing agent, wherein the base oil is an oil mixture of poly-alpha-olefin and refined bio-oil. The preparation method of the biolubricant comprises following steps: part of the dispersing agent, the lubricating agent and the antioxidant are sequentially added to poly-alpha-olefin and subjected to heating, stirring and uniform mixing, and oil A is obtained; besides, the remaining dispersing agent, the pour point depressant and the viscosity index improver are sequentially added to the refined bio-oil and subjected to heating, stirring and uniform mixing, and oil B is obtained; finally, the oil B is slowly dropwise added to the oil A, an oil mixture is subjected to heating stirring, low-temperature stirring and normal-temperature centrifugal separation, and the biolubricant is obtained. The biolubricant is good in viscosity-temperature performance, environment-friendly and biodegradable, has good low-temperature starting performance for a vehicle engine, and can have a good lubricating effect in a wider temperature range.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to a wide temperature range biological lubricating oil for vehicles and a preparation method thereof. Background technique [0002] With the popularization of domestic cars in our country, the lubrication problems related to cars have become increasingly prominent. Under normal circumstances, vehicles have a lubricating oil change cycle specified by the manufacturer. However, due to the impact of extreme weather in recent years, even if the vehicle is changed according to the requirements specified by the manufacturer, failures due to poor lubrication still emerge in endlessly, and sometimes even affect the vehicle. and personnel safety. Although there are some multi-grade lubricating oil products on the market at present, they are mainly equipped for conventional winter and summer temperatures. They are obviously insufficient for vehicle lubrication in extreme climates. , The fluid...
