Embodiment 1

[0024] A vegetable oil-based high-temperature-resistant lubricating oil, which is made of the following raw materials in parts by weight: 20 parts of corn oil, 12 parts of castor oil, 10 parts of hydroxyl-terminated dimethyl diphenyl polysiloxane, and 3 parts of polyvinyl alcohol , 3 parts of ethanolamine, 4 parts of polyethylene glycol monomethyl ether, 1 part of ferrocene, 1 part of preservative, 3 parts of composite graphite powder, and 2 parts of modified nano-silica.

[0025] The composite graphite powder is prepared by the following method: slice the paraffin wax, place it in an electric drying oven, raise the temperature to fully melt the paraffin wax, keep it warm, then add graphite powder of equal quality, stir evenly with the graphite powder, After standing and cooling at room temperature, pulverize and pass through a 200-mesh sieve to obtain paraffin-modified composite graphite powder.

[0026] The modified nano silicon dioxide is prepared by the following method: ...

Embodiment 2

[0037]A vegetable oil-based high-temperature-resistant lubricating oil, which is made of the following raw materials in parts by weight: 30 parts of corn oil, 15 parts of castor oil, 13 parts of hydroxyl-terminated dimethyl diphenyl polysiloxane, and 4 parts of polyvinyl alcohol , 5 parts of ethanolamine, 6 parts of polyethylene glycol monomethyl ether, 2 parts of ferrocene, 2 parts of preservative, 4 parts of composite graphite powder, and 3 parts of modified nano-silica.

[0038] This example is the same as Example 1 except that the formulation dosage is different from Example 1. The preparation method of the vegetable oil-based high temperature resistant lubricating oil in this example is also the same as Example 1.

Abstract

The invention discloses a vegetable oil-based high temperature resistant lubricating oil and a preparation method thereof, and belongs to the technical field of lubricating oil. The lubricating oil ofthe invention is prepared by using corn oil, castor oil, hydroxyl-terminated silicone oil, polyvinyl alcohol, ethanolamine, methoxypolyethylene glycols, ferrocene, a preservative, composite graphitepowder and modified nano silicon dioxide as raw materials. According to the preparation method, the paraffin-modified graphite powder is added, which promotes the graphite to exert heat conduction effect, effectively reduces temperature of a friction surface and prolongs the service life of the lubricating oil. Meanwhile, the modified nano silicon dioxide sol reduces the agglomeration of particlesafter oleophilic modification and has the effect of damage repairing, anti-wear and wear reducing by cooperating with the modified graphite powder. The modified nano silicon dioxide sol and the modified graphite powder promote each other to realize the technical effect of high temperature resistance, high efficiency, wear reducing and anti-wear of the lubricating oil of the invention. The preparation process is simple and low in cost, and has wide application potential.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a vegetable oil-based high-temperature resistant lubricating oil and a preparation method thereof. Background technique [0002] At present, lubricating oil is widely used in chemical industry, textile, machinery and other industries. With the further promotion of economic globalization, especially the rapid development of the automobile industry, and the strengthening of environmental protection and energy saving requirements, although the total supply of lubricating oil has not increased significantly, the demand for high-grade lubricating oil has become increasingly strong. Lubricating oil is mainly composed of base oil and additives, of which base oil is the main component of lubricating oil, accounting for more than 85%. [0003] Lubricant base oils are divided into vegetable oil, mineral oil and synthetic oil. Vegetable oil has the characteristics of biodegradation...
