Embodiment 1

[0030] A biodegradable and environmentally friendly lubricant that includes the following components:

[0031] 2wt% chitin-polyurethane fiber, 0.5wt% antiemulsifier, 2.2wt% antioxidant, 1.2wt% rust inhibitor, 1.3wt% dispersant, 1.2wt% defoamer, residual plant mixed base oil.

[0032] Among them, the anti-emulsifier is the anti-emulsifier T1001, the antioxidant is di-tert-butyl-p-cresol, the rust inhibitor is sodium sulfonate, the dispersant is polyisobutene monosorcinimide, and the defoamer is methyl silicone oil.

[0033] The vegetable base oil is canola oil and castor oil mixed in a 2:1 mass ratio.

[0034] The chitin - polyurethane fiber preparation method comprises the following steps:

[0035] (1) The polyurethane material is dissolved in an organic solvent to form a polyurethane solution, and the concentration of the polyurethane solution is 10wt%;

[0036] (2) Add 4wt% chitin whiskers in polyurethane solution, stir evenly to form a spinning solution, stir at a speed of 800 ...

Embodiment 2

[0048] A biodegradable environmentally friendly lubricant, compared with Example 1, the difference is that the use of chitin powder added to the polyurethane solution to form a spinning solution, the remaining steps and components are the same as Example 1.

[0049] Control group 1

[0050] A biodegradable environmentally friendly lubricating oil, compared with Example 1, the difference is that the composition content is not added chitin - polyurethane fiber, the remaining steps and components are the same as Example 1.

[0051] Example 1-2 and the control group produced environmentally friendly lubricants for performance testing.

[0052]1. Use four-ball friction and wear testing machine, load 392N, test 60min, oil pool lubrication, test steel ball for 12.7mmGCr15 standard steel ball, test the friction coefficient and average mold diameter of environmentally friendly lubricating oil, and determine the bearing performance of lubricant according to the four-ball method of GB / T3142-...

Embodiment 3

[0061] A biodegradable and environmentally friendly lubricant that includes the following components:

[0062] 3wt% chitin-polyurethane fiber, 0.5wt% antiemulsifier, 2.5wt% antioxidant, 1.5wt% rust inhibitor, 1.5wt% dispersant, 1.5wt% defoamer, residual plant mixed base oil.

[0063] Among them, the anti-emulsifier is the anti-emulsifier T1001 and the anti-emulsifier D114 mixed, the antioxidant is, thiophosphate dioctyl zinc salt, the rust inhibitor is a mixture of polymer carboxylic acid and phosphate, the dispersant is calcium petroleum sulfonate and magnesium petroleum sulfonate, and the defoamer is methyl silicone oil.

[0064] The vegetable base oil is a mixture of rapeseed oil and castor oil in a mass ratio of 2:1.5.

[0065] The remaining preparation methods and steps are the same as in Example 1.

[0066]The environmentally friendly lubricating oil prepared by this embodiment is tested for four-ball friction wear and biodegradation, the friction coefficient measured by the...

Abstract

The invention relates to the field of lubricating oil preparation, and discloses biodegradable environment-friendly lubricating oil and a preparation method thereof.The environment-friendly lubricating oil is prepared from 1 wt%-3 wt% of chitin-polyurethane fibers, 0.2 wt%-0.5 wt% of a demulsifying agent, 1.5 wt%-2.5 wt% of an antioxidant, 1.0 wt%-1.5 wt% of an antirust agent, 1.0 wt%-1.5 wt% of a dispersing agent, 1.0 wt%-1.5 wt% of a defoaming agent and the balance plant mixed base oil, the chitin-polyurethane fiber is prepared by carrying out electrostatic spinning on chitin and polyurethane; the plant mixed base oil comprises rapeseed oil and castor oil, various properties of the lubricating oil can be mutually balanced by using the chitin-polyurethane fiber, and the viscosity coefficient of the lubricating oil can be improved while the lubricating oil has high biodegradation rate.

Description

Technical field [0001] The present invention relates to the field of preparation of lubricating oil, in particular a biodegradable environmentally friendly lubricating oil and a method of preparation thereof. Background [0002] Lubricating oil has a wide range of applications in aviation, automotive, mechanical processing, transportation, metallurgy, coal, construction, light industry and other industries. The vast majority of traditional lubricating oils are based on mineral oil, which plays a huge role in reducing friction and wear, saving energy, prolonging mechanical life and meeting the lubrication needs under harsh working conditions, however, while it is widely used, it will inevitably enter the environment through transportation, leakage, sputtering, overflow or inappropriate discharge, which seriously pollutes soil and water resources and destroys the ecological environment and ecological balance. [0003] Compared with mineral oil, vegetable oil has excellent lubricati...
