Definitions
- the invention relates to a method for preparing a graphene/metal composite board, and belongs to the technical field of composite materials.
- Graphene is a new type of two-dimensional nanomaterial with a strength of up to l. OlTpa, which is 100 times that of structural steel and a density of 1/5 of structural steel. Under the background that traditional methods have been difficult to increase the strength of metal materials, graphene has become another important direction for reinforced metal materials.
- Graphene is a monolayer or a molecular layer of a sheet-like structure with a length ranging from 20 ⁇ m to 50 ⁇ m.
- the main preparation methods are physical methods and chemical methods. Currently, a large number of graphenes are prepared by chemical methods on the market. Due to the low density of graphene, the strength of the metal material is increased while the density of the material is lowered.
- graphene also has excellent properties such as ultra-high electron mobility (200,000 cm2/V ⁇ S), electrical conductivity, thermal conductivity (5000 W/m ⁇ K), and Young's modulus (l lOOGPa), so the graphene composite
- metal materials such as aluminum, titanium, and magnesium, it is expected that a composite material having a light weight, high strength, and a combination of structural functions such as electrical conductivity and heat conduction can be obtained.
- the invention provides a method for preparing a graphene/metal composite board according to the above prior art situation, which adopts a slurry method to prepare a high-strength graphene composite metal sheet, and the graphene slurry is sprayed by a spraying process. Coating on the surface of the metal sheet, and then preparing a high-strength graphene composite sheet by a hot rolling process, the high-strength Graphene composite sheets have excellent engineering application prospects in light armor materials, aviation and aerospace.
- the method for preparing the graphene/metal composite sheet is characterized in that: the method is:
- the graphene/polyvinyl alcohol mixed slurry is applied to the upper and lower surfaces of the metal sheet by spraying, and the thickness of the coating layer is greater than 100 ⁇ m;
- the graphene metal sheets obtained by the step (6) are bonded together to form a graphene composite metal sheet by hot rolling.
- the hot rolling method allows the graphene to be uniformly dispersed into the matrix of the metal sheet, which significantly increases the strength of the sheet metal.
- the method adopts ultrasonic vibration to prepare a monodisperse graphene homogeneous solution, and then mixes monodisperse graphene with a polyvinyl alcohol solution to prepare graphene/polyethylene.
- the alcohol mixed slurry is composited with a metal plate by using a graphene/polyvinyl alcohol mixed slurry, and the dispersibility of the graphene can be ensured;
- the graphene composite sheet is prepared by stacking, which is beneficial to the uniform dispersion of graphene into the substrate of the sheet, and exerts the reinforcing effect of graphene;
- graphene has better toughness than reinforcing materials such as SiC.
- Graphene can also have a lubricating effect during rolling, which is beneficial to roll forming of metal;
- the present invention achieves molecular bonding of graphene and a metal plate, and can better retain the intrinsic physical properties of graphene and metal materials;
- the process of the invention is simple, easy to realize the preparation of large-scale and large-sized graphene composite plates, and reduces the production cost, and has excellent engineering application prospects in the fields of light armor materials, aviation and aerospace.
- Embodiment 1 Embodiment 1
- the graphene aluminum alloy sheet obtained by the step (6) is subjected to hot rolling at a hot rolling temperature of 440 ° C to 480 ° C to prepare a graphene composite aluminum alloy sheet.
