Problems solved by technology

[0004] The technical problem mainly solved by the present invention is that a considerable part of the components in general lubricating oil are difficult to be degraded by microorganisms, and the loss of lubricating oil into the environment will cause serious pollution to the environment, and the lubricating oil prepared from vegetable oil has poor oxidation stability. Sludge and deposits will be produced in the process, and a method for preparing lubricating oil using vegetable oil as a base oil is provided. The invention extracts watermelon seed oil from watermelon seeds, and then esterifies the watermelon seed oil to obtain watermelon seed oil. Watermelon seed oil is mixed with auxiliary agents such as vinyl ether, ethylenediamine oleate, succinate, triphenyl thiophosphate to prepare lubricating oil. The present invention uses watermelon seed oil as the base oil of lubricating oil, and Its esterification modification can improve the problem of its poor oxidation property. Watermelon seed oil is degradable and environmentally friendly. The lubricating oil prepared has good lubricating performance and strong oxidation resistance, prolonging the service life of engine lubricating oil and reducing deposits generation, and the production cost is low, the preparation process is simple, and it is suitable for industrial production

[0027] First, take 600g of watermelon seeds from the melon, dry the watermelon seeds completely, and shell them to obtain the watermelon kernels. The watermelon kernels are crushed and sieved to obtain a 70-mesh watermelon kernel powder. Mix 1:5 with 5% hydrochloric acid by mass fraction, and after mixing, ultrasonically disperse for 10 minutes at 30°C and 300W power to obtain a dispersion; adjust the pH of the above dispersion to 4.7 with a concentration of 2mol / L hydrochloric acid, and add The total mass of 5% compound enzyme is enzymatically hydrolyzed at 45°C for 5 hours, and the enzymolysis mixture is placed in a water bath, heated to a boiling state for 15 minutes to inactivate the enzyme. After inactivating the enzyme, the mixture is centrifuged at 14000r / min for 20min. The supernatant was obtained, and the supernatant was allowed to stand for stratification to obtain an oil phase, the compound enzyme was a mixture of protease and cellulase at a mass ratio of 2:1; the ab...

Abstract

The invention discloses a method for preparing lubricating oil with plant oil as base oil and belongs to the field of lubricating oil. Watermelon seed oil is extracted from watermelon seeds, then the watermelon seed oil is subjected to esterification reaction to obtain watermelon seed grease, and the watermelon seed grease is mixed with vinyl ethyl ether, EDO-86, succinate, triphenyl thiophosphate and other auxiliaries to prepare the lubricating oil. The watermelon seed oil serves as the base oil of the lubricating oil and is subjected to esterification modification, the problem that oxidization performance is poor is solved, the watermelon seed oil is degradable and environmentally friendly, the prepared lubricating oil is good in lubricating performance and high in oxidation resistance, the service life of the engine lubricating oil is prolonged, generation of sediment is reduced, production cost is low, the preparation process is simple, and the method is suitable for industrial production.

Description

technical field [0001] The invention discloses a method for preparing lubricating oil by using vegetable oil as base oil, belonging to the field of lubricating oil. Background technique [0002] Green lubricating oil can also be called biodegradable lubricating oil or environmentally friendly lubricating oil. It refers to the ecological effect of lubricating oil: the lubricating oil itself and its depleted products will not cause harm to the ecological environment, and are allowed by the environment to a certain extent. . In the process of biodegradation of green lubricating oil, hydrocarbons are first cracked by the decomposing enzymes produced by microorganisms themselves, and then further oxidized and decomposed into small molecules until CO 2 and H 2 O, finally achieves the purpose of degradation, and the process is accompanied by the loss of substances, H 2 O and CO 2 generation, O 2 The process of consumption, energy release, and increase of microbial biomass requ...
