Problems solved by technology

[0002] At present, in the existing external thermal insulation system of building exterior walls, most of them are interface layer, structural bonded mortar layer, thermal insulation layer, alkali-resistant mesh cloth layer, crack-resistant plastering mortar layer, putty layer, decorative layer on the wall base layer. The surface layer is stacked successively, and some of them are poured on site. The biggest disadvantage is that the degree of industrialization is low, the effect of heat preservation and fire prevention is poor, and the construction quality is not easy to control.
Recently, some factory-produced thermal insulation and decoration integrated composite panels have appeared in the market, but there are also obvious problems such as thermal insulation effect, but poor fire protection function, especially serious engineering safety hazards in structural installation.
In addition, because the above-mentioned integrated composite board does not adopt any protective measures on its surface, not only the moisture-proof performance is poor, but also when the surface is stained with stains, after a certain period of time, the stain invades into the interior of the composite board, causing the composite board to be difficult to scrub. as a result of
In addition, due to the poor shielding effect of the composite panel, its sound insulation effect is also poor

Embodiment 1

[0026] Step 1, prefabricating coated metal coils, the specific process of prefabricating coated metal coils is: cleaning the metal coils after uncoiling, and drying after cleaning. Cleaning the metal coils is to spray the metal coils with acid and alkali solution Spray, remove the grease on the surface of the metal coil to passivate the metal surface, and dry the cleaned metal coil in a temperature environment of 180°C. Apply an adhesive to the cleaned and dried metal coil, and the adhesive is a PU type two-component oily polyurethane. Send the metal sheet coated with adhesive to the laminating machine with oven, glue and coat the PVC decorative film on the metal coil to obtain the coated metal coil, wherein the thickness of the PVC decorative film is 0.12mm, Bake the glued PVC decorative film for 1 minute at a temperature of 120°C.

[0027] In step 2, the prefabricated film-coated metal coil is shaped by a roll bender to form a basic mold with a groove body. During the roll...

Abstract

The invention relates to a production process of a metal hard foam polyurethane composite decorative sheet. The production process comprises the following steps of step 1, prefabricating a coated metal coil; step 2, producing a basic die with a groove body after molding the prefabricated coated metal coil through a rolling bending machine; and step 3, placing a foaming material into the groove body of the basic die to be foamed to produce hard foam polyurethane, then covering a metal film on the surface of the hard foam polyurethane through the guide, sending the metal film into an insulation box to be thermally insulated after shaping the metal film, and producing the metal hard foal polyurethane composite decorative sheet. After the metal hard foam polyurethane composite decorative sheet is installed, a seamless fireproof, damp-proof, heat-preserving and sound-proof wall which is easy to scrub is formed.
