Abstract

The invention discloses a high-strength composite aluminum foil structure and a preparation method thereof. The high-strength composite aluminum foil structure comprises a foaming body, wherein the foaming body is a polymethacrylimide foam board, the upper side and the lower side of the foaming body are each provided with an adhesive film layer, the outer sides of the two adhesive film layers are each provided with an aluminum foil in an adhesive mode, and the adhesive film layers are thermosetting adhesive layers which can resist a temperature higher than 270 DEG C. The preparation method of the high-strength composite aluminum foil structure comprises the following steps: preparing materials, slicing a foaming body material, flattening a composite aluminum foil structure blank, and setting the flattened composite aluminum foil structure blank in a temperature environment of 270-350 DEG C. The strength, hardness and other mechanical and physical properties of the formed high-strength composite aluminum foil structural material are greatly improved; and meanwhile, the composite material is light and thin, and the requirement for light weight can be met.

Description

technical field

[0001] The invention relates to a high-strength composite aluminum foil structure. Background technique

[0002] Aluminum foil is a commonly used material for industrial production, including packaging materials, heat insulation materials, sound insulation materials, electroacoustic conversion materials, etc. As an electroacoustic conversion material, sometimes aluminum foil needs to meet certain requirements in strength and light weight, but The simple aluminum foil material is relatively soft, and its hardness and strength are insufficient, so it is difficult to meet the requirements of the market.

[0003] The publication number is CN213798436U, and the patent title is "a moisture-proof and antibacterial aluminum foil composite material". The upper end of the aluminum reinforcement layer is provided with a first antibacterial layer, the upper end of the first antibacterial layer is provided with a first heat-resistant layer, the upper end of the first hea...
