Problems solved by technology

However, the organic polymer materials used in metal foam composite panels based on organic polymers are easy to burn, and most composite panels use polymer adhesives to glue and splice porous foam alloys and metal panels in the production process. The adhesive is easy to age, which leads to a short service life of the composite board. At the same time, when the adhesive splicing is subjected to strong impact, it is easy to cause the matrix to crack and make its safety factor low.

Abstract

The invention discloses a flame-retardant low-density foamed alloy composite plate and a preparation method thereof. The flame-retardant low-density foamed alloy composite plate comprises a porous foamed alloy core, a brazing filler metal and metal panels, wherein the porous foamed alloy core is prepared by covering a substrate of polyether sulfone resin sponge and polyester resin sponge of a three-dimensional net structure, with a chemical nickel plating layer and an electric nickel plating layer in a double-layer adhesion manner; the metal panels are welded on the upper side or the upper side and the lower side of the porous foamed alloy core through the brazing filler metal. The flame-retardant low-density foamed alloy composite plate has both functions of battery shielding and sound insulation, is capable of making rail traffic vehicles relatively energy-saving, safe and comfortable, and can be widely applied to the field of rail traffic vehicles.
