Explosion-suppressing material and preparation method thereof

Abstract

The invention belongs to a preparation method of an explosion-suppressing material. The explosion-suppressing material comprises the following chemical compositions by weight percent: 0.3-0.5 percent of Si, 0.1-0.3 percent of Fe, 0.15-0.25 percent of Cu, 1.0-1.5 percent of Mn, 1.0-1.5 percent of Mg, 0.1-0.3 percent of Zn, 0.15-0.25 percent of Ti, 0.03-0.06 percent of La, 0.05-0.09 percent of Ce and the balance Al. A grain structure of the explosion-suppressing material is refined by adopting a repeated heating forging and pressing method. The explosion-suppressing material provided by the invention has excellent extrusion resistance, collapse prevention, zero dreg-falling and high-strength explosion-suppressing property. The performance indexes of the explosion-suppressing material, such as strength, plasticity, fracture toughness and fatigue resistance, are greatly increased according to the preparation method; the technology is simple and is easily performed; and the service life of the explosion-suppressing material is prolonged.

Description

technical field [0001] The invention belongs to a novel explosion-suppressing material and a preparation method thereof. Background technique [0002] Explosion suppression material is a honeycomb-like bulky material installed in a flammable and explosive fluid storage container. It is a functional material that can prevent or inflammable and explosive fluid from burning and exploding. [0003] The current anti-explosion materials are mainly aluminum alloy anti-explosion materials. After the aluminum alloy explosion suppression material is placed in the flammable and explosive fluid storage container, because the mesh in the explosion suppression material laminate forms a honeycomb structure, the inner cavity of the fuel tank is divided into many small "small compartments". These "small compartments" "It can curb the spread of flames. At the same time, this honeycomb structure has good thermal conductivity per unit volume. It must quickly absorb most of the heat released by...

Problems solved by technology

[0004] However, the disadvantages of the current anti-explosion materials are that the material has large internal crystals, is not compact, hard and brittle, has no toughness and elongation, and is easy to break and drop slag.

Moreover, the entire honeycomb mesh material is placed in the fuel tank. Due to the shaking and stamping of the oil in the tank, it is very easy to cause the collapse of the explosion suppression material, that is, the compression of the entire honeycomb mesh, causing it to lose its explosion suppression function, and the entire honeycomb mesh is collapsing. During the process, the slag will be crushed under pressure, and the slag will seriously block the oil circuit of the fuel tank, often causing the oil circuit to fail to ignite, seriously affecting the quality
