Abstract

The invention relates to engine lubricating oil, and particularly relates to a preparation method of degradable engine lubricating oil, belonging to the technical field of lubricating oil. The preparation method comprises the following steps: uniformly mixing vegetable oil and sodium hydrogen carbonate, heating, preserving heat by reflux, cooling and taking the supernate; distilling the supernate and collecting fractions in a 170-190 DEG C section; and adding vulcanized triphenyl phosphate, succinimide, isobutanol, trialkyl ester oleate phosphate, diglycol butyl ether, 2-aminoethyl heptadecenyl imidazole dodecenyl sodium succinate, an antioxidant, a plasticizer and calcium petroleum sulfonate into the fractions, heating, preserving by reflux and cooling. The engine lubricating oil provided by the invention is good in lubricating effect and can be biodegraded, so that the environmental pollution caused by abandoning the lubricating oil is avoided.

Description

[0001] technical field [0002] The invention relates to an engine lubricating oil, in particular to an engine lubricating oil capable of natural degradation, and belongs to the technical field of lubricating oil. [0003] Background technique [0004] The engine is the heart of a car, and it contains many parts that operate at high speed, such as pistons, crankshafts, camshafts, intake and exhaust valves, etc. The friction between these parts and other parts during operation is quite severe. If there is no lubricating oil, these moving parts that rub against each other will wear out quickly, causing the engine to malfunction or even be destroyed. [0005] The basic function of engine lubricating oil is to form a reliable oil film between metal friction parts to cut off the dry friction between metal friction parts. In addition, engine lubricating oil has other functions, including: lubrication and cooling , Anti-corrosion effect, sealing effect, cleaning effect. Engine...
