Abstract

The invention discloses a special alloy barrier and explosion suppression material. The barrier and explosion suppression material includes the following raw materials in weight fractions: 0.3-0.4% of silicon, 0.7-0.9% of iron, 0.2-0.3% of copper, 2.5-3.5% of manganese, and 0.1% of magnesium. ~0.2%, zinc 0.2~0.3%, titanium 0.1~0.2%, silver 0.4~0.6%, nickel 0.01~0.03%, and the balance is aluminum. The invention discloses a preparation method of a special alloy barrier explosion suppression material, which is prepared by firstly mixing and preheating various metal powders, then sintering, warm rolling into a blank, finally rolling into a foil, and slit stretching. The special alloy barrier and explosion suppression material prepared by the invention has good electrical conductivity, is not easy to collapse, and is not easy to generate debris; the preparation process is simple, the preparation method consumes less energy, the raw material combination is good, and the deformation is not easy to occur.

Description

technical field [0001] The invention relates to the technical field of barrier and explosion suppression materials, in particular to special alloy barrier and explosion suppression materials. Background technique [0002] In the field of storage and transportation of flammable liquids or gases, people will take precautions; but despite this, due to some unforeseen and sudden reasons, chemical plants, oil refineries, gas stations, automobiles, oil trucks, oil depots , oil storage tanks and other accidents caused explosions, which caused irreparable huge losses to the property of the country and the people. In view of the needs of the market, various countries in the world have successively developed various anti-explosion materials, such as polyurethane foam, paper materials, film materials, etc., but these materials have poor chemical stability in petroleum products, are very easy to crack and break, and cause liquid pollution. Suitable for long-term use. The burning and e...
