Embodiment approach

[0034] As a preferred implementation manner, after the step S205, it also includes:

[0035] Step S206, sticking a protective film on the upper surface and / or lower surface of the hollow aluminum-plastic panel.

[0036] In order to protect the aluminum film on the surface of the hollow aluminum-plastic panel from abrasion, in this step, a protective film may also be pasted on the upper surface and / or lower surface of the hollow aluminum-plastic panel. After the user installs the hollow aluminum-plastic panel, tear off the protective film, which can ensure that the aluminum film of the hollow aluminum-plastic panel will not be worn during transportation or installation.

[0037] Further, as a preferred implementation manner, after the step S205, it also includes:

[0038] Step S207 , cutting the hollow aluminum-plastic panel according to actual needs to obtain a finished hollow aluminum-plastic panel.

[0039] The hollow aluminum-plastic panel produced on the production line ...

Abstract

The invention is suitable for the technical field of building and decoration, and provides a production method of a hollow aluminum-plastic panel. The production method comprises the following steps: injecting a plastic particle raw material into an extruder for plasticizing to obtain a plastic hot melt; pushing the plastic hot melt into a hollow panel die; extruding the plastic hot melt from an outlet of the hollow panel die; cooling and setting the extruded plastic hot melt through a vacuum setting device to obtain a hollow plastic panel; dragging out the hollow plastic panel through a traction device; thermally treating the hollow plastic panel through a heating device; covering a glue film and an aluminum film on the upper surface and the lower surface of the thermally treated hollow plastic panel; and then performing laminating forming through a heating laminating device, and cooling to obtain the hollow aluminum-plastic panel. According to the hollow aluminum-plastic panel provided by the invention, the adhesion degree of the aluminum film and the inner layer hollow plastic panel is high, and the whole mechanical structure is stable and hard to deform.

Description

technical field [0001] The invention belongs to the fields of architecture and decoration, and in particular relates to a production method of a hollow aluminum-plastic panel. Background technique [0002] Aluminum-plastic panel is a kind of building decoration material processed on special aluminum-plastic panel production equipment with aluminum plate as the surface material and polyethylene plastic as the core material. Because aluminum-plastic panels are easy to process and shape, they have been widely used in various fields such as building curtain walls, exterior wall decoration and advertising, and interior decoration. [0003] But existing aluminum-plastic panels are all solid aluminum-plastic panels. When manufacturing solid aluminum-plastic panels, plastic pre-shaped plates are extruded through a general-purpose mold, then cooled and shaped by a cooling device, and finally adhesive film and aluminum film are pasted and pressed together. However, because the inner ...
