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 appea

Example Embodiment

[0025] Example 1:

[0026] Step 1. Prefabrication of film-coated metal coils. The specific process of prefabrication of film-coated metal coils is: cleaning the metal coils after uncoiling, drying after cleaning, and cleaning the metal coils by spraying the metal coils with acid and alkali solutions. Pour, remove the grease on the surface of the metal coil to passivate the metal surface. Drying is to dry the cleaned metal coil in a temperature environment of 180°C. The cleaned and dried metal coil is coated with an adhesive, and the adhesive is a PU type two-component oily polyurethane. The metal sheet coated with adhesive is sent to a laminating machine with an oven, and the PVC decorative film is glued and coated on the metal coil to obtain a film-coated metal coil. The thickness of the PVC decorative film is 0.12mm. Bake the glued PVC decorative film for 1 minute at a medium temperature of 120°C.

Cleaning the metal coils involves spraying the metal coils with acid and alkali solutions. Pour, remove the grease on the surface of the metal coil to passivate the metal surface. Drying is to dry the cleaned metal coil in a temperature environment of 200°C. The cleaned and dried metal coil is coated with an adhesive, and the adhesive is a PU type two-component oily polyurethane. The metal sheet coated with adhesive is sent to a laminating machine with an oven, and the PVC decorative film is glued and coated on the metal coil to obtain a film-coated metal coil. The thickness of the PVC decorative film is 0.18mm. Bake the glued PVC decorative film for 3 minutes at a temperature of 200℃.

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.

Description

technical field [0001] The invention relates to a decorative board, in particular to a metal rigid foam polyurethane composite decorative board and a production process thereof. Background technique [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 layers are stacked in sequence, 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 po...
