Abstract

A preparation method of a thermal insulation composite material comprises the following steps: firstly, mixing foaming thermal insulation material batch and carrying out compression moulding; secondly, preparing a microcrystalline glass sheet material through fusion; thirdly, taking out the prepared foaming thermal insulation material, putting the material on the upper surface of the prepared microcrystalline glass sheet material of 880 DEG C, and compounding the foaming thermal insulation material and the microcrystalline glass sheet material; fourthly, sending the composite sheet material into a foaming furnace of 850 DEG C through a mesh belt, foaming and insulating at 850 DEG C for 25-45 min, cooling at the cooling rate of 10-20 DEG C / min to 600 DEG C, and standing at constant temperature for 30 min; and finally, cooling at the cooling speed of 1-2 DEG C / min from 600 DEG C to room temperature so as to obtain the thermal insulation composite board. According to the invention, the thermal insulation foam glass material and the microcrystalline glass building material are bonded at high temperature into an integral body; the bonding process by the use of cement mortar during the construction process is reduced; material usage is minimized; and construction procedure is simplified. Meanwhile, the prepared thermal insulation composite board's thermal insulation material has advantages of high strength, low water absorption, low density and low heat conductivity coefficient.

Description

technical field [0001] The invention relates to a preparation method of a composite material, in particular to a preparation method of a thermal insulation composite material. Background technique [0002] Foam glass is made of waste glass, fly ash, mica, perlite, pumice powder, volcanic ash and other materials as the main raw materials, adding foaming agent, modifier, accelerator, etc. After heating at 750-900°C in a specific mold, the glass is softened, foamed, and annealed to form a porous glass material filled with countless uniform bubbles. Foam glass has physical properties such as low density, high strength, and small thermal conductivity. It not only has the inherent permanence, safety, reliability, chemical corrosion resistance, and ant-mouse resistance of glass materials, but also has the advantages of being compatible with other buildings. Compared with materials, it also has a series of superior properties such as thermal insulation, waterproof and moisture-proo...
