Technical Field

[0001] The utility model relates to the technical field of composite plates, in particular to a foam aluminum composite plate. Background Art

[0002] Foam aluminum is made by adding additives to pure aluminum or aluminum alloy and then undergoing a foaming process. It has the characteristics of both metal and bubbles. It has low density, high impact absorption, high temperature resistance, strong fire resistance, corrosion resistance, sound insulation and noise reduction, low thermal conductivity, high electromagnetic shielding, strong weather resistance, filtering ability, easy processing, easy installation, high forming precision, and surface coating. Foam aluminum has excellent physical properties, chemical properties, mechanical properties and recyclability. These excellent properties of foam aluminum give it broad application prospects in today's material field and it is a very promising engineering material, especially in the transportation industry, aerospace industry and building structure industry. Foam aluminum sheet is a sheet whose main material is foam aluminum.

[0003] The existing patent number CN201520468826.0 discloses a transparent foam aluminum composite sheet, which uses the light curing characteristics of UV resin to obtain better composite strength and transparency by selecting the distance between the ultraviolet light source and the surface of the foam aluminum substrate, the ultraviolet wavelength range, the light energy and the irradiation time.
