Embodiment 1

[0026] The galvanized coil with a thickness of 1mm enters the embossing unit, and the galvanized coil processed by the embossing unit enters the cold bending forming unit, heats the galvanized coil to 30°C, and coats the surface of the galvanized coil with The pressure of 1.3MPa was simultaneously sprayed with PTMEG-1000 polytetrahydrofuran ether glycol and 4,4'-diphenylmethane diisocyanate with a molar ratio of 1:1.5, and allowed to stand for 70 minutes to obtain a polyurethane layer with a thickness of 48.7mm; After standing for 70 minutes, the product will continue to move forward under the thrust of cold bending, and then lay a glass fiber cloth with a thickness of 0.3mm on the product injected with PTMEG-1000 and 4,4'-diphenylmethane diisocyanate , and then the product covered with glass fiber cloth is sent to a double-layer hot-press conveyor, and shaped at 43°C; finally, a composite wallboard with a thickness of 50mm is obtained, and the composite wallboard includes a la...

Embodiment 2

[0028] The galvanized coil with a thickness of 1mm enters the embossing unit, and the galvanized coil processed by the embossing unit enters the cold bending forming unit, and the coil layer with concave and convex parts is obtained through roller extrusion; among them, the concave part Both the convex part and the convex part are rectangular, and the ratio of the length to the width of the rectangle is 1:0.6. Heat the coil layer to 30°C, and simultaneously spray polytetrahydrofuran ether glycol and 4,4'-diphenyl with a molar ratio of 1:1.5 in the concave part of the coil layer at a pressure of 1.3MPa Methane diisocyanate, standing for 70 minutes, to obtain a polyurethane layer with a thickness of 48.7mm; the product after standing for 70 minutes will continue to move forward under the thrust of cold bending, and then sprayed with PTMEG-1000 and 4,4'-di Lay a glass fiber cloth with a thickness of 0.3mm on the product of phenylmethane diisocyanate, and then send the product cov...

Embodiment 3

[0030] The aluminum coil with a thickness of 0.5mm enters the embossing unit, and the aluminum coil processed by the embossing unit enters the cold bending forming unit, and the coil layer with concave and convex parts is obtained through roller extrusion; among them, the concave and convex The convex parts are all rectangular, and the ratio of the length to the width of the rectangle is 1:0.3. Heat the coil layer to 45°C, and simultaneously spray polytetrahydrofuran ether glycol and 4,4'-diphenyl with a molar ratio of 1:1.3 in the concave part of the coil layer at a pressure of 1.5MPa Methane diisocyanate, standing for 90 minutes, to obtain a polyurethane layer with a thickness of 49.3mm; the product after standing for 90 minutes will continue to move forward under the thrust of cold bending, and then sprayed with PTMEG-1000 and 4,4'-di Lay a glass fiber cloth with a thickness of 0.2mm on the product of phenylmethane diisocyanate, and shape it at 35°C; finally obtain a compos...

Abstract

The invention relates to a manufacturing method of a composite wall board. The manufacturing method comprises the following steps that a raw material roll board is put in an embossing unit, then the raw material roll board processed by the embossing unit is put in a cold-bending forming unit, the raw material roll board obtained by the cold-bending forming unit is laid with a polyurethane layer; a fireproof layer is laid on the polyurethane layer, and finally the composite wall board including a roll board layer, the polyurethane layer and the fireproof layer in sequence is obtained. The composite wall board manufactured by adopting the manufacturing method has the advantage of rapid installation and also has excellent heat preservation and insulation, sound insulation, noise reduction, fire prevention, flame retardance, light weight and abrasion resistance. In addition, the manufacturing method of the composite wall board is simple and easy to operation, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a composite wallboard and its manufacturing method and application. Background technique [0002] In recent years, the country has vigorously advocated green energy-saving decorative materials. With the development of science and technology and the improvement of people's material and cultural living standards, people have higher and higher requirements for living environment and environmental protection, especially in residential areas and office buildings. People hope It can be more beautiful, safe and comfortable, thermal insulation and sound insulation and noise reduction. Yet the body of wall on the market is still not ideal in terms of thermal insulation and sound insulation effects. Especially in today's situation of lack of land resources, energy shortage, and more and more dense high-rise buildings, there is an urgent need for a new type of wall panel that ca...
