The specific implementation process for preparing the graphene metal laminated composite material by using the preparation device is as follows:
s1, placing the metal substrate in the sub-cavity: the feed inlet 710 on the left side wall of the integrated chamber 100 is opened, and 11 copper foils with the thickness of 25 μm are placed one by one on the conveyor belt 311 in the sub-chamber 120, so that a vacant sub-chamber 120 is left between two adjacent copper foils during the placement. Then, 10 silver foils with a thickness of 15 μm are placed one by one on the conveyor belt 311 in the vacant sub-chamber 120 between two adjacent copper foils, and finally the sealing door 730 is fixedly mounted on the left side wall of the integrated chamber 100 again by using a flange, and the feed opening 710 is sealed again.
S2, adjusting parameters in the integrated cavity: the air in the integrated chamber 100 is evacuated through the vacuum line 520, so that the air pressure in the integrated chamber 100 reaches 100Pa (the air pressure in the integrated chamber 100 is obtained through a pressure gauge on the vacuum line 520), and then the vacuum valve is closed, and the vacuum pump is closed to stop working. Then, a valve of the shielding gas pipe 513 is opened, and a shielding gas (in this embodiment, the shielding gas is nitrogen, in other embodiments, the shielding gas may be other inert gas such as argon, etc.) enters the integrated chamber 100, and in this step, the flow rate of the shielding gas may be controlled by a flow controller of the shielding gas pipe 513. After the internal pressure of the integration chamber 100 is restored to the normal pressure, the vacuum valve is opened so that the excessive shielding gas is discharged through the vacuum line 520, thereby making the inside of the integration chamber 100 in a micro-positive pressure state. Then, a second heating system corresponding to the sub-chamber 120 with the metal foil 800 placed inside is started, and the two pairs of corresponding sub-chambers 120 are heated by the second heating system, so that the temperature in the sub-chamber 120 with the copper foil is raised to 1020 ℃, and the temperature in the sub-chamber 120 with the silver foil is raised to 890 ℃.
S3, graphene growth: the valves of the carbon source pipe 511 and the auxiliary gas pipe 512 are opened, and a gaseous carbon source is introduced into the integrated chamber 100 through the carbon source pipe 511, in this embodiment, the gaseous carbon source is methane, and meanwhile, an auxiliary gas is introduced into the integrated chamber 100 through the auxiliary gas pipe 512, and the auxiliary gas is hydrogen. During this period, the protective gas is continuously introduced into the integrated chamber 100, and graphene grows on the surfaces of the copper foil and the silver foil. The time for introducing the gaseous carbon source and the hydrogen is 10 min. In this process, gaseous carbon source (methane), auxiliary gas (hydrogen) and protective gas (nitrogen) enter each sub-chamber 120 through the gas outlet on the gas inlet manifold 510, and each sub-chamber 120 can be filled with all the above-mentioned gases, so that graphene can grow smoothly.
S4, hot press forming: after the gaseous carbon source (methane) and the auxiliary gas (hydrogen) are introduced for 10min, the valves on the carbon source pipe 511 and the auxiliary gas pipe 512 are closed, and the protective gas is continuously introduced into the integrated chamber 100 so as to flush away the residual methane and hydrogen. Meanwhile, the second heating system is turned off and the first heating system is turned on, the heating and the heat preservation of the sub-chamber 120 are stopped, and the hot pressing platform 220 and the pressing plate 210 are heated and heat preserved (because part of heat is dissipated into the main chamber 110 during the operation of the second heating system, the hot pressing platform 220 and the pressing plate 210 have a certain temperature, and the time required for the temperature of the hot pressing platform 220 and the pressing plate 210 to rise to the preset temperature is short). The metal foil 800 (copper foil and silver foil) grown with graphene in the sub-chamber 120 is transferred into the main chamber 110 by using the transfer mechanism 300, specifically, the driving rod 320 is pushed rightward, so that the conveyor belt 311 is driven by a rightward driving force to rotate clockwise, thereby driving the metal foil 800 (copper foil or silver foil) on the conveyor belt 311 to move rightward, the metal foil 800 moves to the right end of the conveyor belt 311, and then the right end of the metal foil 800 slides onto the hot-pressing platform 220 along the guide part 221, so that the metal foil 800 is transferred once. Then, the second driving member 240 drives the hot pressing platform 220 to rise by a distance which is the same as the distance between the same points on the two vertically adjacent conveyor belts 311, so that the top end of the guiding component 221 on the hot pressing platform 220 can be connected with the right end of the previous conveyor belt 311. The above operation is repeated, so that the metal foil 800 in each sub-chamber 120 is transferred onto the hot pressing platform 220 by the transfer mechanism 300, and the stacking of the metal foil 800 is completed. Moreover, since the copper foil and the silver foil are sequentially disposed from top to bottom in the sub-chamber 120 according to the sequence of copper foil-silver foil- … … copper foil-silver foil-copper foil, after the metal foil 800 is transferred onto the hot-pressing platform 220, the two metal foils 800 (copper foil and silver foil) are vertically stacked in an alternating manner by twenty-one layers. After all the metal foils 800 are transferred to the hot-pressing platform 220, the first driving part 230 drives the pressing plate 210 to move downwards, the pressing plate 210 applies pressure to the metal foils 800 stacked on the hot-pressing platform 220, in the step, the pressure of hot-pressing forming is 30MPa, and the pressure maintaining time of the hot-pressing forming is 30min, so that the copper foil and the silver foil in the main cavity 110 are subjected to hot-pressing sintering, and the graphene-copper-silver laminated composite material is obtained.
S5, cooling and taking materials: after hot press molding, the first driving part 230 drives the pressing plate 210 to move upwards for resetting, the second driving part 240 drives the hot pressing platform 220 to move downwards for resetting, meanwhile, cooling water is continuously input into the cooling cavity 610 in the side wall of the integrated cavity 100 through the water inlet pipe 620, and the cooling water flows out from the water outlet pipe 630 after absorbing heat, so that the integrated cavity 100 is cooled. After the temperature in the integrated chamber 100 is reduced to room temperature, the sealing door 730 at the discharge port 720 is opened, the graphene-copper-silver laminated composite material is taken out through the discharge port 720, and finally, the valve on the protective gas pipe 513 is closed to stop the introduction of the protective gas.
In this embodiment, the graphene growth step and the hot press molding step are integrated in the integrated chamber 100, so that the metal foil does not contact with the outside air in the process of preparing the composite material, thereby avoiding adverse effects of the outside environment and improving the yield, stability and uniformity of the product. In addition, the embodiment also avoids the processes of cooling and taking out firstly, stacking and transferring later and heating and hot press molding in the prior art, thereby not only reducing the operation flow, shortening the production period, improving the production efficiency, but also effectively reducing the energy consumption.
