Embodiment 1

[0024] A graphene engine oil is mainly composed of the following raw materials by mass percentage: 0.03%-0.09% of nano-graphene, 0.015%-0.03% of dispersant, and the balance of base oil.

[0025] In this embodiment, the nano-graphene sheet diameter D50 is 2.5 μm or less.

[0026] In this embodiment, the dispersant is a powder dispersant with lipophilic groups.

Embodiment 2

[0028] A preparation method of graphene oil, comprising the following steps:

[0029] S1. First, inject the base oil into the stirring equipment, then add the dispersant to the base oil, and stir at medium speed for 30 minutes;

[0030] S2. Next, the nano-graphene is added to the base oil at a constant speed, stirred at a high speed with a multi-stage high-speed disperser for 2 hours, allowed to stand for 30 minutes, and then continued to be stirred for 2 hours, and the finished product is obtained after the system is stabilized.

Embodiment 3

[0032] A graphene oil stirring device, the stirring device comprises a stirring tank 1, an upper motor 2 and a feeding port 3 are arranged on the top of the stirring tank 1, a lower motor 4 and a discharging port 5 are arranged on the bottom of the stirring tank 1, and the upper motor 2 is connected by transmission The upper stirring rod 6 and the lower motor 4 are connected to the lower stirring rod 7 by transmission. The lower end of the upper stirring rod 6 is embedded in the top of the lower stirring rod 7, and the two are in clearance fit. A lower stirring blade 9 is arranged on the outside of 7, and both the upper stirring blade 8 and the lower stirring blade 9 are of bifurcated structure, and the two are dislocated. Specifically, the base oil is first injected into the stirring tank 1, then the dispersant is added to the base oil, the upper motor 2 and the lower motor 4 are turned on, and the two respectively drive the upper stirring rod 6 and the lower stirring rod 7 to...

Abstract

The invention discloses graphene engine oil as well as a preparation method and equipment thereof. The graphene engine oil is mainly prepared from the following raw materials in percentage by mass: 0.03 to 0.09 percent of nano graphene, 0.015 to 0.03 percent of dispersing agent and the balance of base oil. The high-purity graphene is adopted, can be uniformly dispersed in an oily system for a long time under the action of the dispersing agent, and is not easy to precipitate; the graphene used in the invention does not chemically react with the metal surface of the engine, the inner wall of the engine is protected completely through physical adsorption film formation, and wear between internal friction pairs is reduced; the used graphene can be used for filling and repairing cylinder wall abrasion in a high-temperature and high-pressure environment when an engine works; meanwhile, carburization is formed on the inner wall surface of the engine after long-time use, the surface strength is improved, and the service life of the engine is prolonged; the used graphene can be uniformly coated in the engine along with the reciprocating motion of the piston, so that the effect of a micro bearing is achieved, sliding friction is changed into rolling friction, and the friction resistance is reduced.

Description

technical field [0001] The invention relates to the technical field of graphene oil production, in particular to a graphene oil, a preparation method and equipment thereof. Background technique [0002] With the continuous development of the economy, the car has now become the main means of transportation for people. The engine is the most important component of the car. During the operation of the car engine, the oil plays the role of lubrication, sealing, rust prevention, shock absorption and cooling to ensure the normal operation of the car engine. Adding suitable engine oil to the engine can effectively reduce the mutual wear of the internal friction pair surfaces, improve the internal working environment of the engine, save energy consumption, and reduce the emission of harmful substances in the exhaust. [0003] Graphene is the thinnest two-dimensional material currently found in nature, with excellent properties such as high strength, high lubricity, and high thermal...
