The graphene aluminum alloy mixed powder is obtained by dispersing 0.5 g graphene powder ultrasonically into absolute ethanol for 2 hours, and then add aluminum alloy particles into the absolute ethanol under argon atmosphere for ultrasonic treatment for 30 minutes for obtaining graphene aluminum alloy mixed suspension. USE - Method for preparing graphene reinforced aluminum-based composite material. ADVANTAGE - The method prepares the graphene reinforced aluminum-based composite material in a simple, precise, cost-effective and eco-friendly manner with excellent surface quality and mechanical properties. DETAILED DESCRIPTION - Graphene reinforced aluminum-based composite material preparation involves taking 100 g aluminum alloy block, 5 g graphene powder, 5000 ml absolute ethanol, 50 g boron trioxide, and 800000 cm3 argon. The absolute ethanol is poured into ultrasonic cleaning machine, and then placed quartz crucible and aluminum alloy block in ultrasonic cleaning machine to clean for 6 minutes for removing surface impurities of the quartz crucible and aluminum alloy block. 50 g aluminum alloy block is mechanically cut to obtain aluminum alloy particles with a diameter of 3 mm. The graphene aluminum alloy mixed powder is obtained by dispersing 0.5 g graphene powder ultrasonically into absolute ethanol for 2 hours, and then add aluminum alloy particles into the absolute ethanol under argon atmosphere for ultrasonic treatment for 30 minutes for obtaining graphene aluminum alloy mixed suspension. The obtained graphene aluminum alloy mixed suspension is simultaneously subjected to mechanical stirring and ultrasonic treatment for 1 hour, and then filtered and dried under vacuum conditions to obtain graphene aluminum alloy mixture. The graphene aluminum alloy mixture is put into ball mill tank of ball mill for ball milling for 30 minutes for obtaining graphite aluminum alloy mixed powder. The graphene aluminum alloy mixed slurry is obtained by placing 25 g boron trioxide and graphene aluminum alloy mixed powder into quartz crucible into melting furnace. Argon gas is introduced into the smelting furnace to make the smelting furnace reach the normal pressure state. An ultrasonic vibration device is provided to vibrate and mix the aluminum alloy melt and graphene in the smelting furnace to obtain graphene aluminum alloy mixed slurry, and then naturally cooled to obtain solid graphene-reinforced aluminum-based composite material and boron trioxide. The quartz crucible is taken out from the smelting furnace, and then peel off the quartz crucible and boron trioxide for obtaining solid graphene reinforced aluminum matrix composite material.
