Method for producing metal decorating surface heat-insulating plate with anti-thermal deformation structure

Abstract

The invention discloses a method for producing a metal decorating surface heat-insulating plate with an anti-thermal deformation structure. The method comprises the following steps: (1) feeding an aluminium alloy plate or a zinc plated or aluminium and zinc plated steel plate which forms a metal decorating surface layer into a pressing moulding machine through a screen open-type unwinding machine for performing pressing moulding treatment; (2) uniformly mixing isocyanate and premixed polyether polyol according to the ratio of 1:1 in a polyurethane pouring machine, coating the metal decorating surface layer with a mixture to form a polyurethane heat-insulating layer, then, covering the polyurethane heat-insulating layer with an aluminium foil, a glass fibre fabric, a cement base fabric, an embossed steel plate or an embossed aluminium foil which forms an interlayer, and sizing through a laminating machine; (3) feeding a cured and moulded plate into an electric heating treatment box through a conveying belt for performing heat treatment, wherein the heating temperature in the heat treatment box is at least 50 DEC G, and the heat treatment time is at least one minute; (4) uniformly pouring phenolic foam resin on the bottom surface of the plate which is produced in the step (3) through a pouring metering pump to form a base layer, feeding the base layer in a laminating conveying machine, and cutting the moulded plate into required sizes through a cutting machine.

Description

technical field [0001] The invention relates to a method for producing a metal-finish heat-preservation board with a heat-deformation-resistant structure. Background technique [0002] There are two directions for the promotion and application of thermal insulation and decorative integrated panels in recent years: one uses inorganic decorative panels (cement fiber pressurized panels, silicon-calcium panels, etc.) thermal insulation and decorative integrated panels, and the other is thermal insulation decorative panels with metal finishes. At present, both the two types of thermal insulation and decorative integrated panels have major problems. In the process of industrial development, there are the following defects: the advantage of inorganic decorative thermal insulation and decorative panels is that the production is simple, and the manufacturer does not need to consider the size. After the panels enter the construction site , cut and constructed on site, this system real...
