Abstract

The invention relates to a magnesium alloy sandwich plate and a preparation method thereof. The magnesium alloy sandwich plate sequentially comprises an upper magnesium alloy panel, a first adhesive layer, a polymer sandwich plate, a second adhesive layer and a lower magnesium alloy panel from top to bottom, wherein the upper magnesium alloy panel and the lower magnesium alloy panel are formed bymagnesium alloy rolled plates through stress relief annealing treatment, the surfaces of the upper magnesium alloy panel and the lower magnesium alloy panel are processed into corrosion resisting films, and the first adhesive layer and the second adhesive layer are formed by high strength glue; and all layers are formed into the magnesium alloy sandwich plate through rolling or hot press curing molding. The magnesium alloy rolled plates with the insulated surfaces are used as the upper magnesium alloy panel and the lower magnesium alloy panel, and the alkalescent high strength glue is used for reliably connecting the upper panel and the lower panel with the polymer sandwich plate to acquire a light sandwich plate with good damping and sound insulating performance and heat insulating performance.

Description

technical field [0001] The invention relates to a composite sandwich board and a preparation method thereof, in particular to a magnesium alloy sandwich board and a preparation method of the magnesium alloy sandwich board. Background technique [0002] Composite sandwich panel is a commonly used mechanical engineering structure with the characteristics of high strength, high sound insulation performance, light weight and low cost. It is composed of upper and lower panels and polymer sandwiches bonded by engineering polymer glue. [0003] The existing composite panel structures are mainly composite sandwich panels and honeycomb panels. Among them, there are mainly two types of composite sandwich panels: one is composed of aluminum alloy panels and polymer sandwich glue, and the other is composed of glass fiber reinforced plastic panels and polymer composite panels. Composed of glued sandwich layers. With the development of lightweight transportation equipment, many original ...
