Embodiment 1

[0013] The 5182 high-magnesium aluminum alloy is prepared according to the following weight percentages for use. The specific chemical composition of the alloy is: Mg=4.65%, Mn=0.35%, Cu=0.10%, Si=0.14%, Fe=0.20%, and Al balance. Among them, Mn, Cu, Si and Fe are added in the form of master alloy. Select 8-12 mesh and 8-18 mesh open-pore puffed vermiculite, put it in the vacuum suction casting mold, adjust the particle gap and air permeability, and preheat the puffed vermiculite at T b Control at 160°C±10°C; melting alloy temperature T c Control 790°C±10°C; after the vacuum degree of the vacuum tank reaches the maximum value, open the connector between the liquid alloy and the suction casting port, open the vacuum hand valve to start suction casting, and use the vacuum hand valve to control the flow rate V of the suction casting alloy liquid c At 0.1m / s, cooling and demoulding after suction casting is completed, the compression performance is measured with a universal testing...

Embodiment 2

[0016] All the other are with embodiment 1. The specific chemical composition of the prepared 5083 high-magnesium aluminum alloy is: Mg=4.5%, Mn=0.5%, Cu=0.10%, Si=0.4%, Zn=0.25%, and Al balance. Choose 12-14 mesh, 12-18 mesh and 12-24 mesh closed-cell puffed vermiculite. T b =440°C±10°C. T c =690°C±10°C. V c = 0.5m / s. The obtained data are summarized in Table 2.

Abstract

A light and porous high-Mg Al-alloy-expanded ore composition is prepared from high-Mg Al-alloy and puffed vermiculite and pearlite through vacuum percolation casting method. Its density is less than 1.9 g / cu*cm. Its advantages are ease control of foam pore, and high compression strength and thermal insulating effect.

Description

Technical field: [0001] The invention relates to a preparation method of a high-magnesium aluminum alloy-natural expanded ore composite material. Background technique: [0002] At present, in the sound-absorbing material industry, there are two types of sound-absorbing materials that are getting more and more attention, one is aluminum foam or magnesium foam; Glass cenospheres isolated from fly ash of power plants. Comparing the two, the advantage of the former is that it can be used alone, but the disadvantages are: ① It is difficult to control the cell quality in the industrial production of pipes, strips, and sheets; ② The foam compression performance is not ideal; ③ The heat insulation effect is not good. The advantage of the latter is that it not only has better noise reduction performance, but also its heat insulation performance is unmatched by most other materials. Its disadvantages are that it cannot be used alone as a tube, belt, sheet, etc. ; Another influential...
