Problems solved by technology

However, this material still has the disadvantages of high brittleness and low elongation. Fragments will appear during use, and even cause oil circuit blockage in serious cases.
Especially during rolling, there may be cracks on the edge of the foil, which will affect the explosion-proof performance of the foil

Embodiment 1

[0013] A barrier and explosion-proof material, made of slit and expanded aluminum alloy foil mesh, with a honeycomb porous structure, the chemical composition weight percentage of aluminum alloy foil is: silicon 0.55%, iron 0.65%, copper 0.13%, manganese 1.3%, zinc 0.1%, titanium 0.15%, aluminum as the balance.

[0014] The manufacturing process steps of the above-mentioned barrier and explosion-proof materials are: rolling the aluminum alloy ingot containing the above-mentioned chemical composition into aluminum alloy foil, cutting it into slit aluminum foil by a slitting machine, then shaping and winding, and then rolling the shaped and rolled aluminum foil. The aluminum foil is tempered, the tempering temperature is 220°C, and the tempering time is 10 hours. The tempered aluminum foil is discharged and slitting and rolling, and then the expanded mesh is expanded into an aluminum foil mesh, and the aluminum foil mesh is stacked. Formed into a mesh barrier explosion-proof mat...

Abstract

The present invention relates to an explosion-barrier material which is made of kerfed and expanded aluminum alloy foil grid, and has a honeycomb-shaped vesicular structure. The chemical components have weight percentages that silicon is 0.3-0.6 percent, iron is 0.3-0.7 percent, copper is 0.1-0.2 percent, manganese is 0.8-1.8 percent, zinc is 0.1 percent, titanium is 0.1-0.2 percent, and aluminum is residual. The present invention also relates to the manufacture process of the explosion-barrier material. The process has steps that the aluminum alloy ingot is rolled to be aluminum alloy foil, cut to be kerfed aluminum foil with a joint cutter, and shaped and wound, then tempering treatment is performed to the shaped and wound aluminum foil with the tempering temperature of 220-240 DEG C and the tempering time durance of 8-10 hours, the aluminum foil after the tempering is discharged, cut and rolled, and then pulled and expanded to be the aluminum foil grid, and the aluminum foil grid is folded and molded to be the grid shaped explosion-barrier material. The explosion-barrier material of the present invention has the advantages of good explosion-proof performance, good flexibility, high tensile strength, and high elongation ratio.

Description

technical field [0001] The invention belongs to the field of metal materials, in particular to a barrier explosion-proof material used as a filling material in an inflammable and explosive liquid or gas storage and a manufacturing process thereof. Background technique [0002] At present, after installing a void material in gasoline, propane, acetylene, ether and other liquid and gas fuels and flammable and explosive fluid storage, the use of the material's heat absorption and retardation can effectively increase the safety of the container in an accident sex. U.S. Patent No. 5000336 "Explosion-proof device for container discloses a kind of explosion-suppressing filling, which has two basic structures: one is to make slits with irregular size and arrangement on the foil, and then expand to Foil mesh with irregular mesh size, shape and arrangement, and then use this foil mesh to make an explosion suppression filling body with irregular mesh. The other is punching, bending, a...
