Inorganic Si-Ca-Al alloy thermal insulation composite board and making method thereof

Abstract

The invention relates to an inorganic silicon calcium aluminum alloy thermal insulation composite board and a manufacturing technology thereof. The thermal insulation composite plate comprise an XPS or an EPS insulation board and an aluminum alloy thin plate; the thermal insulation composite plate also comprises an inorganic silicon calcium plate which is arranged between the XPS or an EPS insulation board and the aluminum alloy thin plate; the inorganic silicon calcium plate and the aluminum alloy thin plate are adhered through epoxy resin adhesive; the adhered plate is pressed under the effect of a cold press till the epoxy rein is completely reacted and dried to form a silicon calcium composite board; after the silicon calcium composite board is taken out, water-based neoprene adhesive is sprayed on the bottom surface of the silicon calcium composite board or the surface of the EPS or the XPS plate for the compound of the thermal insulation board to form a thermal insulation composite board; the thermal insulation composite board is put in the cold press for 10 to 20 hours and then is taken out; the thermal insulation composite board is cut according to different specifications, and then the finished products are obtained. The invention has the advantages of low cost, energy saving, good thermal insulation effect, high strength and convenient construction. The thermal insulation composite board can be widely applied to the external decoration for various walls.

Description

Technical field

[0001] The invention relates to a high-grade heat-insulating decorative material for building energy-saving external walls and a production process thereof, in particular to an inorganic silicon-calcium-aluminum alloy thermal insulation composite board and a production process thereof. Background technique

[0002] At present, the well-known aluminum-plastic panel is a double-layer aluminum composite plastic in the middle. Its structure includes a 0.6mm thick aluminum alloy sheet on the skin, a 0.2mm thick aluminum alloy sheet on the bottom layer, and a 2mm thick composite plastic in the middle, plus EPS or XPS for keel installation. The shortcoming of the insulation board is that the cost is high, and the keel of the steel structure directly produces a thermal bridge; the other structure includes the silicon-calcium XPS composite insulation board, and the shortcoming of its existence is that the inorganic silicon-calcium on the surface The board needs to be ...
