Problems solved by technology

[0004] However, the thermal stability of graphene oxide is poor, and the oxygen-containing functional groups on its surface can easily form stable chemical bonds, which makes it difficult to realize the shear slip between graphene oxide sheets, thus affecting the effective performance of lubricating properties.

Abstract

The invention relates to a nano titanium dioxide modified graphene oxide rolling liquid and a preparation method thereof. The rolling liquid is composed of nano titanium dioxide modified graphene oxide, oleic acid, triethanolamine, water-based borate, glycerin and deionized water. Oleic acid, triethanolamine, glycerol and water-based borate are sequentially added into deionized water, and are completely dissolved to obtain a primary solution; a graphene oxide-titanium dioxide nano composite material prepared by an improved solvothermal method is added into the primary solution, and ultrasonicdispersion is carried out by using an ultrasonic cell disruptor to avoid agglomeration or layering among nano particles, thereby obtaining the uniform and stable water-based nano rolling liquid. The nano titanium dioxide is used for modifying the graphene oxide, so that the tribology and the rolling lubricating property of the graphene oxide are enhanced while the dispersion stability of the graphene oxide is enhanced. Through deposition of the graphene oxide-titanium dioxide composite nanoparticles, a carbonaceous lubricating film and a carbonaceous protective film can be formed on the surface of the steel plate so as to obtain better rolled surface quality.

Description

technical field [0001] The invention belongs to the field of lubricating cold-rolled steel plates, and in particular relates to a nano-titanium dioxide-modified graphene oxide rolling fluid and a preparation method thereof. Background technique [0002] The friction and wear generated in the cold rolling process lead to energy consumption and equipment failure. The importance and necessity of lubrication is beyond doubt. Although the traditional rolling oil can basically meet the requirements of the production process, it is very easy to cause environmental pollution and is harmful to human health. Due to its excellent cooling performance, flame retardancy, low cost and low pollution, water-based rolling fluid is the main direction of current research on environmentally friendly high-performance rolling fluid. [0003] Graphene, as a new two-dimensional nanomaterial, has excellent thermal conductivity and friction resistance. The shear force between graphene sheets is smal...
