A waterproof and deformation-resistant aluminum-wood composite board

Abstract

This utility model relates to the field of aluminum-wood composite panel technology and discloses a waterproof and deformation-resistant aluminum-wood composite panel. The utility model includes: a honeycomb aluminum layer, serving as a metal intermediate support layer to provide high-strength support; a solid wood layer and a composite adhesive layer, wherein the solid wood layer is fixed to both sides of the honeycomb aluminum layer under the hot-pressing adhesive of the composite adhesive layer, forming a wood-like texture on the outside, initially mimicking the effect of solid wood board; and a decorative layer fixed to the outer wall surface of the solid wood layer, specifically a paint layer fixed by spraying, drying, and curing, or a decorative paper layer fixed by adhesive. Traditional aluminum-wood composite panels are bonded by adhesive film between the upper and lower planes (K-side) and the plane of the wood board, resulting in limited bonding area, especially on the K-side. This improved device forms more bonding surface on both the solid wood layer side and the honeycomb aluminum layer side, particularly within the holes of the honeycomb aluminum layer (F-side).

Description

Technical Field

[0001] This utility model relates to the field of aluminum-wood composite board technology, and in particular to a waterproof and deformation-resistant aluminum-wood composite board. Background Technology

[0002] Traditional aluminum-wood composite panels are waterproof and deformation-resistant. However, due to the honeycomb structure design of the aluminum panels and the different materials, the bonding strength is generally low, and the strength and toughness of the adhesive area will gradually decrease with the increase of service life. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problems mentioned above, a waterproof and deformation-resistant aluminum-wood composite board is provided, which solves the above problems.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A waterproof and deformation-resistant aluminum-wood composite panel, comprising:

[0006] The honeycomb aluminum layer serves as a metal intermediate support layer, providing high-strength support.

[0007] The solid wood layer and the composite adhesive layer are fixed to both sides of the honeycomb aluminum layer by the hot-pressing adhesive of the composite adhesive layer, forming a wood-like texture on the outside, which firstly imitates the effect of solid wood board.

[0008] The decorative layer is fixed to the outer wall of the solid wood layer, specifically by spraying, drying and curing the paint layer, or by gluing the decorative paper.

[0009] The composite adhesive layer is viscous before curing. After hot pressing, it is cured between the solid wood layer and the honeycomb aluminum layer and partially embedded in the hexagonal holes of the honeycomb aluminum layer. It is glued and fixed to the inner wall of the hexagonal holes and the ends of the hexagonal holes are sealed and fixed. This effectively increases the connection strength and connection area of ​​the solid wood layer and the honeycomb aluminum layer after they are glued together. Furthermore, the composite adhesive layer forms a filler at the ends of the hexagonal holes of the honeycomb aluminum layer after curing, thereby enhancing the strength of the honeycomb aluminum layer.

[0010] Preferably, the composite adhesive layer includes hard particles with a particle diameter smaller than the pore size in the honeycomb aluminum layer and environmentally friendly adhesive. Specifically, it can be plastic particles and a two-component water-based wood adhesive. It should be noted that since the plastic particles will not react directly with the two-component water-based wood adhesive to generate new materials, they should not be considered as new materials.

[0011] Preferably, a rough sanding layer is provided on the side of the solid wood layer near the honeycomb aluminum layer, which can be obtained by sanding its surface with sandpaper.

[0012] Preferably, the surface roughness Ra (mm) of the rough sanding layer is between 0.5 and 3, which can effectively increase the adhesive strength of the solid wood layer.

[0013] The advantages and positive effects of this utility model are as follows: Traditional aluminum-wood composite panels are bonded by gluing the upper and lower planes (K-side) and the plane of the wood board together with an adhesive film. The bonding area is limited, especially on the K-side. After the improvement of this device, more bonding surfaces are formed on both the solid wood layer side and the honeycomb aluminum layer side, especially in the holes of the honeycomb aluminum layer (F-side), which effectively enhances the adhesive strength. Furthermore, the composite adhesive layer has good strength after curing, effectively improving the resistance to deformation and increasing the service life compared to the prior art.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention. The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings:

[0021] like Figure 1-4 As shown, the waterproof and deformation-resistant aluminum-wood composite board of this utility model includes:

[0022] The honeycomb aluminum layer 14 serves as a metal intermediate support layer, providing high-strength support.

[0023] Solid wood layer 11 and composite adhesive layer 12, the solid wood layer 11 is fixed to both sides of the honeycomb aluminum layer 14 under the hot pressing and gluing action of the composite adhesive layer 12, forming a wood texture on the outside, firstly imitating the effect of solid wood board;

[0024] The decorative layer 10 is fixed to the outer wall of the solid wood layer 11, specifically by spraying, drying and curing the paint layer, or by adhesive bonding of decorative paper.

[0025] The composite adhesive layer 12 is viscous before curing. After hot pressing, it is cured between the solid wood layer 11 and the honeycomb aluminum layer 14 and partially embedded in the hexagonal holes of the honeycomb aluminum layer 14. It is glued and fixed to the inner wall of the hexagonal holes and the ends of the hexagonal holes are sealed and fixed. This effectively increases the connection strength and connection area of ​​the solid wood layer 11 and the honeycomb aluminum layer 14 after gluing. Furthermore, the composite adhesive layer 12 forms a filler at the ends of the hexagonal holes of the honeycomb aluminum layer 14 after curing, thereby enhancing the strength of the honeycomb aluminum layer 14.

[0026] Preferably, the composite adhesive layer 12 includes hard particles with a particle diameter smaller than the honeycomb pore size in the honeycomb aluminum layer 14 and environmentally friendly adhesive. Specifically, it can be plastic particles and a two-component water-based wood adhesive. It should be noted that since the plastic particles will not react directly with the two-component water-based wood adhesive to generate new materials, they should not be considered as new materials.

[0027] Preferably, a rough sanding layer 13 is provided on one side of the solid wood layer 11 near the honeycomb aluminum layer 14. Specifically, it can be obtained by sanding its surface with sandpaper.

[0028] Preferably, the surface roughness Ra (mm) of the rough sanding layer 13 is between 0.5 and 3, which can effectively increase the adhesive strength of the solid wood layer 11.

[0029] Traditional aluminum-wood composite panels are bonded by adhering the upper and lower planes (K-side) and the plane of the wood board with an adhesive film. The bonding area is limited, especially on the K-side. After the improvement of this device, more bonding areas are formed on both the solid wood layer 11 side and the honeycomb aluminum layer 14 side, especially in the holes (F-side) of the honeycomb aluminum layer 14, which effectively enhances the adhesive strength. Furthermore, the composite adhesive layer 12 has better strength after curing.

[0030] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
