Embodiment 1

[0014] Embodiment 1: First, aluminum, magnesium and other alloying elements are smelted into alloy ingots. The elemental components and mass percentages of the ingots are: Mg0.8%, Fe0.3%, Si0.6%, Mn1.8, Cu0 .1%, Zn0.2%, rare earth metal 0.45% (specific components: Y0.1%, Ce0.1%, La0.2%, Sc0.05%), the balance is aluminum and unavoidable impurities. Then the cast ingot is rolled into 0.05-0.01mm rare earth aluminum-magnesium alloy foil, sent to the slitting machine to cut the slit, and then sent to the stretching machine to stretch into a grid-shaped metal sheet.

Embodiment 2

[0015] Embodiment 2: First, aluminum, magnesium and other alloying elements are smelted into alloy ingots. The elemental components and mass percentages of the ingots are: Mg1.8%, Fe0.5%, Si0.5%, Mn1.6, Cu0 .2%, Zn0.1%, rare earth metal 0.50% (specific components: Y0.1%, Ce0.1%, La0.2%, Sc0.1%), the balance is aluminum and unavoidable impurities. Then the cast ingot is rolled into 0.05-0.01mm rare earth aluminum-magnesium alloy foil, sent to the slitting machine to cut the slit, and then sent to the stretching machine to stretch into a grid-shaped metal sheet.

Embodiment 3

[0016] Embodiment 3: First, aluminum, magnesium and other alloying elements are smelted into alloy ingots. The elemental components and mass percentages of the ingots are: Mg1.2%, Fe0.4%, Si0.5%, Mn1.2, Cu0 .15%, Zn0.15%, rare earth metal 0.77% (specific components: Y0.15%, Ce0.15%, La0.4%, Sc0.07%, the balance is aluminum and unavoidable impurities. Then the The cast ingot is rolled into 0.05-0.01mm rare earth aluminum-magnesium alloy foil, sent to the slitting machine to cut the slit, and then sent to the stretching machine to stretch into a grid-shaped metal sheet.

Abstract

The invention relates to a rare earth aluminum-magnesium alloy barrier explosion-proof material, which is prepared from the following chemical components, by mass, 0.8-1.8% of Mg, 0.3-0.5% of Fe, 0.3-0.6% of Si, 0.8-1.8% of Mn, 0.1-0.2% of Cu, 0.1-0.2% of Zn, 0.45-1.0% of rare earth metals, and the balance of aluminum and inevitable impurities. According to the present invention, the chemical components are rationally designed, and rare earth metal modification is performed on the aluminum-magnesium alloy, such that the aluminum-magnesium alloy explosion-proof material has advantages of high strength, good toughness, corrosion resistance, strong thermal cracking ability, and the like; after the aluminum-magnesium alloy explosion-proof material of the present invention is placed in a fuel tank, when the fuel tank encounters open fire, static electricity, impact, lightning strike and an accidentally crashing accident, flame burning can be separated, flame propagation speed can be slowed, flame burning height can be significantly reduced, and the container can be prevented from explosion, such that good explosion-proof performance and good explosion inhibition performance are provided.

Description

technical field [0001] The invention relates to an aluminum-magnesium alloy explosion-proof material, in particular to a rare-earth aluminum-magnesium alloy barrier explosion-proof material. Background technique [0002] At present, combustible or combustible substances such as petroleum and methane have become indispensable chemical energy sources for human beings. However, the transportation or storage of these resources increases the risk of fire and explosion. According to relevant data, fires caused by combustible or combustible materials or fires caused by explosions are more difficult to control than ordinary fires. Usually, once a fire or explosion occurs, firefighters can only do aftermath work in order to minimize losses. [0003] In response to the above problems, in the past 20 years, domestic and foreign R&D personnel have conducted special research on explosion-proof and explosion-suppressing materials used for combustible or combustible materials, and achieved...
