Explosion suppression material and preparation method thereof

The invention relates to an explosion suppression material and a preparation method thereof and belongs to the technical field of functional metal materials. According to the preparation method, an aluminum alloy foil base body is split by a grooving machine and shaped and wound, and then the shaped and wound aluminum alloy foil base body is split and rolled; the rolled aluminum alloy foil base body is dragged and extended to be of a meshed structure, wound to be of a three-dimensional cellular porous hexagonal structure, and then laminated to be in a required shape; the laminated aluminum alloy foil base body is fed into a nitriding furnace for nitriding; and the nitrided laminated aluminum alloy foil base body is placed in a high-temperature reaction furnace, subjected to oxidation treatment in the air atmosphere, and cooled to the room temperature alternately through cyclic temperature difference, and the explosion suppression material is obtained. By means of the explosion suppression material and the pre
