Description

Technical Field

[0001] The utility model belongs to the technical field of decorative materials and relates to a light composite aluminum-plastic plate. Background Art

[0002] As a new type of decorative material, aluminum-plastic panels have been introduced to China from Germany in the late 1980s and early 1990s. They have quickly gained popularity due to their economy, variety of optional colors, convenient construction methods, excellent processing performance, excellent fire resistance and noble quality.

[0003] Aluminum-plastic panels are widely used in building exterior walls, curtain wall panels, renovation of old buildings, interior wall and ceiling decoration, advertising signs, display stands, purification and dust prevention projects, etc., and are a new type of building decoration material.

[0004] Existing composite aluminum-plastic panels generally adopt solid texture, with high density and insufficient lightness. In addition, the core structure strength is low and the impact resistance is poor, which can easily lead to deformation of the panel or fracture of the core. Utility Model Content

[0005] The utility model aims to provide a light composite aluminum-plastic plate with light weight and high strength in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A lightweight composite aluminum-plastic panel comprises a plastic core plate and an aluminum plate, characterized in that the plastic core plate comprises an upper plastic sheet, a honeycomb core and a lower plastic sheet fixedly connected in sequence from top to bottom, the honeycomb core is evenly distributed with a number of penetrating honeycomb holes, the aluminum plate is arranged on the upper surface of the upper plastic sheet and the lower surface of the lower plastic sheet, a decorative film layer is fixedly connected to the upper surface of the aluminum plate above the upper plastic sheet, and a protective coating is fixedly connected to the upper surface of the decorative film layer.

[0008] The lightweight composite aluminum-plastic panel reduces the weight of the plastic core board by setting the honeycomb core, thereby reducing the overall mass of the panel, making it lighter and reducing the load on the building, and the structure of the honeycomb core also enhances the internal strength of the plastic core board, so that the overall structural strength of the panel is large, and the bending and fracture resistance are stronger; the arrangement of the aluminum plate makes the surface of the panel have good weather resistance and fire resistance, and is easy to clean and maintain; the arrangement of the decorative film layer allows the surface of the panel to have different colors, making it more decorative and aesthetically pleasing, and the arrangement of the protective coating protects the integrity of the decorative film layer, slows down the fading, aging or damage of the decorative film layer, and prolongs its service life.

[0009] In the above-mentioned lightweight composite aluminum-plastic panel, the aluminum plate includes an upper aluminum plate and a lower aluminum plate, the upper aluminum plate is fixedly connected to the upper surface of the upper plastic sheet, the lower aluminum plate is fixedly connected to the lower surface of the lower plastic sheet, and the above-mentioned decorative film layer is fixedly connected to the upper surface of the upper aluminum plate.

[0010] The upper aluminum plate and the lower aluminum plate cover the plastic core plate. The aluminum material makes the plate surface have good weather resistance and fire resistance, a long service life and easy cleaning and maintenance.

[0011] In the above-mentioned lightweight composite aluminum-plastic panel, an adhesive layer is provided between adjacent two of the upper aluminum plate, upper plastic sheet, honeycomb core, lower plastic sheet and lower aluminum plate, and the upper aluminum plate, upper plastic sheet, honeycomb core, lower plastic sheet and lower aluminum plate are sequentially fixedly connected by the adhesive layer.

[0012] The provision of the adhesive layer ensures that the connection between two adjacent layers in the board is firm and not easy to separate, thereby increasing the compactness and stability of the overall structure.

[0013] In the above-mentioned lightweight composite aluminum-plastic panel, the decorative film layer is a paint coating, and the decorative film layer is coated and formed on the upper surface of the upper aluminum plate.

[0014] In the above-mentioned lightweight composite aluminum-plastic panel, the decorative film layer is a powder coating, and the decorative film layer is fixedly connected to the upper surface of the upper aluminum plate by electrostatic spraying.

[0015] Whether the upper surface of the aluminum plate is coated with paint or a decorative film layer is formed using powder electrostatic spraying technology, the plate can be customized in different colors according to different needs. It is more decorative and beautiful, suitable for different usage scenarios, and has high flexibility.

[0016] In the above-mentioned lightweight composite aluminum-plastic panel, the protective coating is a UV coating.

[0017] The transparent UV coating is attached to the surface of the decorative film layer by coating and curing, which protects the decorative film layer without affecting the color of the decorative film layer, slows down the fading, aging or damage of the decorative film layer, and makes the surface of the board easy to clean and maintain.

[0018] In the above-mentioned lightweight composite aluminum-plastic panel, the thickness of the upper aluminum plate is consistent with that of the lower aluminum plate.

[0019] In the above-mentioned lightweight composite aluminum-plastic panel, the thickness of the upper plastic sheet and the lower plastic sheet are consistent.

[0020] Such a structure makes the upper aluminum plate, the upper plastic sheet, the honeycomb core, the lower plastic sheet and the lower aluminum plate form a vertically symmetrical structure, making the overall strength and performance of the plate more balanced.

[0021] Compared with the prior art, the lightweight composite aluminum-plastic panel has a honeycomb structure inside the panel through the setting of the honeycomb core, which reduces the overall weight of the panel, makes it lighter, and reduces the load on the building. At the same time, it also enhances the internal strength of the plastic core panel, so that the overall structural strength of the panel is large, and the bending and fracture resistance are stronger. In addition, the setting of the decorative film layer enables the surface color of the panel to be customized according to different production requirements, and the decorative and aesthetic properties are stronger. The integrity of the decorative film layer is protected by the setting of the protective coating, which slows down the fading, aging or damage of the decorative film layer, making it easy to clean and maintain while extending its service life.
