NOVELTY - Preparing graphene oxide and butyl rubber composite material involves dispersing graphene oxide in water to obtain a graphene oxide dispersion liquid, where the mass ratio of graphene oxide to water in the graphene oxide dispersion liquid is 0.001 to 0.1: 1. The butyl rubber is dissolved in a solvent to obtain a butyl rubber solution, and the mass ratio of the butyl rubber to the solvent in the butyl rubber solution is 0.1 to 1:20. A surfactant aqueous solution is prepared according to a mass ratio of 17: 2 by sodium dodecylbenzenesulfonate and sodium dihydrogen phosphate. The mass ratio of the mass of sodium dodecylbenzenesulfonate and sodium dihydrogen phosphate to water is 0.01: 0.1;. The butyl rubber solution is added to the surfactant aqueous solution at a volume ratio of 0.01: 1 and stirred and dispersed at high speed. After the dispersion is completed, a butyl rubber emulsion is obtained. USE - Method for preparing graphene oxide and butyl rubber composite material. DETAILED DESCRIPTION - The speed of the disperser is 4000 to 9000 rpm, and the dispersion time is 20 to 60 minutes. The graphene oxide dispersion liquid is added to the prepared butyl rubber emulsion at a mass ratio of 0.01: 150, and stirred and mixed to obtain a mixed dispersion liquid. A disperser is added to continue dispersing, the dispersing time is 1 to 10 minutes, and the speed of the dispersing machine is 4000 to 9000 rpm. The sulfurization assistant sulfur, tetramethyldithiothiuram, 2-mercaptobenzothiazole, zinc oxide, stearic acid are added to the mixed dispersion according to 1.25phr, 1.5phr, 1phr, 5phr, 2phr to continue dispersion and obtaining an unvulcanized raw material solution. A disperser is used to continue dispersing, the dispersing time is 1 to 10 minutes, and the speed of the dispersing machine is 4000 to 9000 rpm. The solution in the obtained mixture is removed. CaCl2 is added as a demulsifier to the mixed dispersion, and the mass ratio of CaCl2 to butyl rubber added is 0.01: 0.1. The floc layered mixed dispersion is then separated by oil and water using a paging funnel to obtain unvulcanized raw materials. The unvulcanized raw materials are poured into a watch glass, first use a blast oven to dry for 2 hours, and then transferred to a vacuum oven with a vacuum of 0.1 MPa, and continue to dry for 36 to 64 hours. After drying, the raw materials of graphene oxide and butyl rubber are obtained. The graphene / butyl rubber material can be obtained by hot pressing the raw materials. The hot pressing temperature is 145 to 160 degrees C, the pressure is 13 to 20 MPa, and the time is 10 to 20 minutes.
