preparation example 1

[0065] 300 mg of graphene oxide (purity: 98%, sheet diameter: 20 μm, sheet thickness: 4 nm) was dissolved in water and ultrasonically dispersed to obtain a 5 mg / ml graphene oxide aqueous solution.

[0066] Dissolve 3 mg of sodium tetraborate and 150 mg of sodium dodecyl sulfate in water, and disperse ultrasonically for 10 minutes to obtain a mixed solution of sodium tetraborate and sodium dodecyl sulfate.

[0067] The graphene oxide aqueous solution and the mixed solution were mixed at a rotational speed of 10,000 rpm, and then reacted at 80° C. for 1 hour to obtain a foaming solution.

[0068] 1500 mg of sodium ascorbic acid was mixed with the foaming solution, reacted at 80° C. for 10 h, and then washed with 1 vol% ethanol aqueous solution to obtain graphene hydrogel.

[0069] The graphene hydrogel was frozen at -20°C for 20h, thawed to room temperature, and dried at 65°C for 24h to obtain graphene airgel powder.

Embodiment 1

[0071] Prepare an aluminum alloy honeycomb sandwich (size 200×300×30mm, hole diameter 15mm). A layer of polyurethane adhesive is coated on the first surface of the aluminum alloy honeycomb sandwich to form an adhesive layer A. A calcium silicate board measuring 200 x 300 x 2 mm was attached to the adhesive layer A. 0.1MPa curing treatment for 30min. Set the density to 5kg / m 2 The graphene airgel powder (preparation example 1) is filled in the cavity structure of aluminum alloy honeycomb sandwich core. A layer of polyurethane adhesive is coated on the second surface of the aluminum alloy honeycomb sandwich to form an adhesive layer B.

Abstract

The invention discloses an aluminum alloy honeycomb panel and a production method thereof. The production method comprises the following steps: (1) forming a bonding layer A on the first surface of analuminum alloy honeycomb sandwich, enabling the bonding layer A to be in contact with a panel A, and performing solidification treatment under 0.05-0.25 MPa to combine the aluminum alloy honeycomb sandwich with the panel A; (2) filling the cavity structure of the aluminum alloy honeycomb sandwich with graphene aerogel powder; (3) forming a bonding layer B on the second surface of the aluminum alloy honeycomb sandwich, enabling the bonding layer B to be in contact with a panel B, performing solidification treatment under 0.05-0.25 MPa, depressurizing and then performing solidification so as tocombine the aluminum alloy honeycomb sandwich with the panel B. The aluminum alloy honeycomb panel disclosed by the invention is relatively high in tensile strength.
