Embodiment 1

[0021] (1) Preparation of basic electrolyte.

[0022] Add 0.5 g of aluminum trifluoride to NaCl-CsCl, mix well, and then add 0.1 g of tungsten carbide.

[0023] (2) Growth of aluminum-graphene.

[0024] Put an aluminum sheet with a diameter of 3cm, a height of 1cm, and 0.65% (weight) impurities (silicon 0.62%, zinc 0.03%) into the bottom of the alumina crucible, and place the mixture prepared in (1) on the aluminum sheet , Cover the crucible lid and put it in a vertical heating furnace. Heat to a calcination temperature of 800 ℃ under normal pressure, and the calcination time is 1.5h. After the high temperature calcination is completed, pour the liquid mixture in the crucible into another Cool in an alumina crucible at room temperature for 2 hours. After the molten salt mixture is fully solidified, dissolve it in a sodium chloride solution with a mass fraction of 20%. After filtration, the solid mixture is obtained. Use tweezers to slowly remove the solid mixture. The aluminum shee...

Abstract

A preparation method of aluminum-graphene metal composite material, (1) adding fluoride to alkali metal chloride, mixing, and then adding metal or non-metallic carbide powder; (2) putting aluminum sheet into In the alumina crucible, place the mixture in step (1) on the aluminum sheet, cover the alumina crucible, put it into a vertical heating furnace, raise the temperature to 700-800°C under normal pressure, and calcinate for 0.5-5h; (3 ) Pour the liquid mixture formed in step (2) into the crucible, cool at room temperature for 1-2h, after the liquid mixture is solidified, add a sufficient amount of sodium chloride solution, leave the solid mixture after filtering, and slowly shake the solid mixture with tweezers The aluminum sheet in the sample was clamped out and placed on a cover glass, put into deionized water, changed the water three times, and dried to obtain an aluminum-graphene metal composite. The process of the invention is simple, energy-saving and cheap; the hardness, strength and ductility of the obtained aluminum-graphene composite material are at least 2-3 times higher than those of pure aluminum materials.

Description

Technical field [0001] The invention belongs to the field of functional materials. It relates to aluminum-graphene and its preparation method. Background technique [0002] In recent years, carbon nanomaterials including graphene and carbon nanotubes have become important structural and functional reinforcements for new materials due to their high thermal conductivity, high damping capacity, high elastic modulus, high mechanical strength and good self-lubricity. . Synthesizing new lightweight metal composite materials with high conductivity and hardness is one of the most important goals of modern materials science. One of the directions is to prepare high-content nano- or micro-carbon reinforced aluminum composite materials. Aluminum-based composite materials have the advantages of low density, strong corrosion resistance, excellent electrical and thermal conductivity, and good processing performance, which have become the mainstream of current metal-based composite research....
