Problems solved by technology

Since the thickness of the graphene sheet is only 0.335nm, the strong van der Waals force between the layers makes it easy to agglomerate in the emulsion system, which makes it difficult to show the excellent performance of graphene, which limits its application in metal rolling. Wide application in the field of liquid preparation

Abstract

The invention discloses a graphene high-performance environmental-friendly copper sheet strip rolling liquid and a preparation method thereof, and belongs to the technical field of a lubricant. The rolling liquid comprises main components in percentage by weight: 40 to 50% of colleseed oil, 10 to 15% of polyoxyethylene (20) sorbitan tri-oleate, 1 to 2% of oleic acid, 4 to 10% of alcohol, 0.01 to 0.10% of graphene, 0.5 to 2% of sodium hypophosphite, 5 to 10% of triethanolamine and the balance of water. The preparation method of the graphene high-performance environmental-friendly copper sheet strip rolling liquid comprises the following steps: after adding the graphene into the alcohol to carry out ultrasonic processing for a certain time, mixing with the polyoxyethylene (20) sorbitan tri-oleate, the oleic acid and the colleseed oil to obtain an oil-phase mixed liquor; dissolving the sodium hypophosphite and the triethanolamine in the water, adding into the oil-phase mixed liquor, carrying out shearing stirring for a certain time at a certain rotating speed to obtain stock solution of the rolling liquid, and after diluting the stock solution according to a ratio of 1 to 5 to 10, obtaining the rolling liquid which can be used for rolling machining of a copper sheet strip. According to the invention, raw materials are environmental-friendly; the process is simple; the prepared rolling liquid has no toxicity or pungent odor and has an excellent extreme pressure anti-wear property and storage stability.

Description

technical field [0001] The invention relates to a graphene high-performance environment-friendly copper strip rolling fluid and a preparation method thereof, which is used for lubrication and cooling in the copper strip rolling process and belongs to the technical field of lubricants. Background technique [0002] Rolling is a processing method that uses rolls to roll steel, copper, aluminum and other metal blanks into plates of various specifications. During the rolling process, the friction between the roll and the metal is relatively large, and a large amount of deformation heat and friction heat will be generated. If there is no necessary lubrication and cooling, the surface of the rolled piece will be seriously damaged, the strip product will be unqualified, and even the roll will crack and die. Reduced roll life. Therefore, it is necessary to use a large amount of rolling lubricant to lubricate and cool the friction pair, thereby improving the quality of rolled produc...
