Problems solved by technology

Graphene has good high temperature resistance and friction resistance, and has been applied in the fields of sheet sliding, friction and wear mechanism, and tribology, and there are many researches and reports; but the chemical properties of graphene are stable, and the interaction with other media is weak. There are strong intermolecular forces, making it difficult to disperse in many solvents

preparation example Construction

[0028] The preparation method of modified graphene oxide is: first by chemical oxidation, the graphene surface has oxygen-containing polar groups with high reactivity such as hydroxyl, carboxyl and epoxy groups, to obtain unmodified graphene oxide. Then, through the reaction of organic substances with C12-C22 alkyl groups and oxygen-containing polar groups, C12-C22 alkyl groups are grafted on the surface of unmodified graphene oxide, thereby introducing C12-C22 on the surface of graphene oxide. The grafting of alkyl groups yields modified graphene oxide. Compared with unmodified graphene oxide, modified graphene oxide has oil solubility and better dispersion in base oil, and can undergo coordination reaction with phosphorus-containing additives in base oil to form coordination compounds. Commonly used organic compounds with C12-C22 alkyl groups include oleic acid, castor oil, lauric acid, etc.

Abstract

The invention discloses metal rolling oil containing modified graphene oxide in the field of steel rolling. The metal rolling oil is prepared from the following components in parts by weight: 85 to 90 parts of base oil, 1 to 5 parts of a phosphorus-containing additive, 2 to 4 parts of an emulsifying agent, and 1 to 5 parts of the modified graphene oxide, wherein the surface of the modified graphene oxide is grafted with C12-C22 alkyl, and the modified graphene oxide and the phosphorus-containing additive generate a coordination compound in the base oil. The technical effects are as follows. The lubricating performance of the metal rolling oil is strong, flat steel rolled under high-speed and high-pressure high rolling force and multi-rolling reduction has a glossy surface and high reflectance, the anti-rusting performance of the surface of the flat steel is ensured, and the cleaning performance of a rolling machine can also be ensured. The invention also provides a preparation method of the metal rolling oil containing the modified graphene oxide.

Description

technical field [0001] The invention relates to a metal rolling oil containing modified graphene oxide and a preparation method thereof in the field of steel rolling. Background technique [0002] With the increasing demand for high-strength sheet steel (HSS) and ultra-high-strength sheet steel (UHSS) for automobile sheets and home appliance sheets, the requirements for rolling oil used in rolling are also getting higher and higher. In the case of high pressure, high speed, high rolling force and multiple reductions, the traditional lubricating oil can no longer meet the requirements for lubrication in the rolling process and the surface quality of strip steel. [0003] When rolling at high speed, high pressure, high rolling force and multiple reductions, a large amount of frictional heat is generated between the work rolls and the rolled plate and strip steel. Due to the accumulation of frictional heat on the surface of the work rolls, the surface temperature of the work ro...
