Embodiment 1

[0021] The metal energy-saving decorative composite board is produced by the following method:

[0022] The first step of pretreatment: the panel is made of alloy aluminum veneer, alloy aluminum coil, titanium plate or titanium zinc plate, the thickness is between 0.7mm-1.0mm, and it should have good ductility on the basis of strong rigidity , The alloy aluminum is preferably 3003H24, and the titanium plate and titanium-zinc plate are folded at 180 degrees without tearing, and then folded back to their original positions without cracking.

[0023] First, use fluorocarbon paint to paint the decorative protective layer on the surface of the panel. When the decorative protective layer is metallic color or solid color, the surface of the panel should be three-coated and three-baked. The dry film thickness of the coating should not be less than 28-30um; After drying, apply a layer of protective varnish (fluorocarbon alcohol). Use a wire drawing machine to pull out the pockmarked b...

Embodiment 2

[0026] To prepare metal energy-saving decorative composite panels, the basic steps are similar to those in Example 1, except that: the first step of pretreatment: when the decorative protective layer is imitation marble or granite stone pattern, the panel needs to be coated four times and baked four times, using fluorocarbon paint, Acrylic or polyurethane spraying, the thickness of the coating should not be less than 32-35um, after all the paints are painted and dried, then apply a layer of overcoat protective varnish (fluorocarbon alcohol), the washing resistance does not change after 10,000 times, and the hardness of the pencil Above 2H, the flexibility of the coating is less than 2T, the adhesion is less than grade 1, (acid resistance, alkali resistance) 3%, no change for 72 hours, the resistance to butanone is greater than 100 times (1kg / cm), and the impact resistance rate is 50kg / cm No paint stripping, no cracks, no blistering or falling off after 500 hours of salt resista...

Embodiment 3

[0028] Production of non-metallic energy-saving decorative composite panels, details are as follows:

[0029] The first step of pretreatment: the panel adopts RPC board, the thickness of the board is 5mm-7.5mm, the compressive strength is 200Mpa, the bending strength is 15Mpa, the fracture energy (1000J / square meter), and the wear coefficient is 1.3. First, use fluorocarbon paint to paint the decorative protective layer on the surface of the panel. When the decorative protective layer is metallic or solid, the surface of the panel is coated with four times and baked four times. The dry film thickness of the coating should not be less than 32um; (imitation of marble, granite ) five coats and five bakes, the dry film thickness of the coating should not be less than 38um. Other processing steps are identical with the second step of embodiment 1. The technical requirements are the same as implementing 1.2.

Abstract

The invention relates to a production method for the construction materials, in particular to an energy-saving decoration composite panel, which comprises two steps; wherein, the first step is the pretreatment: a panel is pretreated depending on the material of the panel; a decoration protective layer is coated on the surface of the panel; the second step is compound: the adhesive is coated on the two surfaces of a heat insulation plate of the first layer; then one surface is compounded with the panel and the other surface is compounded with one surface of a metal reinforced layer; the other surface of the reinforced layer is compounded with a heat insulation plate of the second layer coated with adhesive on one surface, finally the panel is compressed tightly and shaped with a board pressing machine. The invention has the advantages of simple technology method, industrial production, combination of the panel, the heat insulation plate and the metal reinforcing plate, coated protective layer for the panel paint film depending on the material and the decorative patterns, rational material choosing for the decoration protective layer, excellent decorative property, good weatherability, high self-cleaning performance, good product quality of industrial production, good performance, and high productivity.

Description

Technical field: [0001] The invention relates to a production method of building materials, especially a production method of a composite board, and also relates to a production line thereof. Background technique: [0002] At present, marble, granite, aluminum veneer, aluminum-plastic panel, glass curtain, etc. are generally used for indoor and outdoor decoration in the construction field. According to the statistics of the Ministry of Construction, there are more than 35 million square meters of curtain wall market in the country every year. The existing products are aluminum-plastic panels. , aluminum veneer, marble, granite, glass curtain wall as the main decoration materials. Most of these products have a single structure, heavy weight, high consumption of materials, high energy consumption, and complicated construction. This alone wastes nearly 100 billion yuan of funds every year, exploits tens of billions of cubic meters of various mineral products, destroys mountain...
