Abstract

The invention discloses an aluminum-based sandwich panel for the construction industry and a preparation method of the aluminum-based sandwich panel. The aluminum-based sandwich board has the structure formed by combing an aluminum panel, a core material and an aluminum panel in sequence, wherein the core material and the panels are in metallurgical bonding; the core material is a composite material consisting of ceramic particles and aluminum; the ceramic particles are any one of or the combination of multiple of alumina balls, alumina hollow balls, pulverized fuel ash particles and floating balls. The preparation method of the aluminum-based sandwich panel comprises the following steps of: filling a mold; preheating the mold in a casting chamber; smelting aluminum in a smelting crucible, generating negative pressure of the casting chamber to enable an aluminium smelting body to enter the mold from bottom to top; condensing the smelting body in the mold in the smelting crucible after pressurization; and carrying out surface treatment on a casting. The aluminum-based sandwich panel prepared by the invention has the functions of temperature preservation, heat insulation, noise reduction and decoration, thus the aluminum-based sandwich panel can be widely applied in the construction field.

Description

technical field [0001] The invention relates to a sandwich panel used in the construction industry, in particular to an aluminum-based sandwich panel which has the functions of fire prevention, heat preservation, heat insulation, noise reduction and decoration. The invention also relates to the aluminum-based sandwich panel Plate preparation method. Background technique [0002] In terms of exterior wall decoration in the construction industry, most of the outer layers are pasted with benzene board or extruded board. Although the paste layer has a good thermal insulation function, the flammability of benzene board paste materials makes it unable to meet the national fire protection requirements. The fires in domestic high-rise buildings in recent years have fully demonstrated this point; in addition, the weather resistance of this type of material is poor, making its life shorter. In terms of interior decoration, many sponge-like high polymers are still used as sound insula...
