Description

Composite wallboard combining natural veneer and aluminum honeycomb plate and manufacturing process thereof
Technical Field
The invention relates to the field of architectural decoration, in particular to a natural veneer and aluminum honeycomb panel composite wallboard.

The aluminum honeycomb panel comprises an aluminum skin and an aluminum honeycomb structure, a high heat conduction value is formed between the aluminum skin and the aluminum honeycomb structure, the expansion and contraction of the inner aluminum skin and the outer aluminum skin are synchronous, and the aluminum honeycomb skin is provided with small holes, so that gas in the panel can freely flow, and the structural deformation can not be caused when the aluminum honeycomb panel expands with heat and contracts with cold. Because the aluminum honeycomb panel has the advantages of high wind pressure resistance, shock absorption, sound insulation, heat preservation, flame retardance, high specific strength and the like, the aluminum honeycomb panel is widely applied to the aspects of high-rise building outer wall decoration, indoor partition wall panels and the like.
The natural veneer is made up by using natural log as base material and adopting multiple processes of planing and cutting, etc. to obtain the veneer with uniform thickness. The natural veneer is non-toxic and environment-friendly, has pure natural wood textures on the surface, emits natural costustoot, can embody the characteristics of natural wood materials in home decoration, greatly reduces the cost compared with pure wood decoration, and is popular and loved by people.
At present, most of the existing wallboards are used after natural wood veneers are adhered on the surfaces of aluminum honeycomb panels so as to combine the advantages of the aluminum honeycomb panels and the natural wood veneers. However, the wall surface is prone to accumulate moisture, the wallboard with the veneer attached thereon has poor waterproof performance, and the natural veneer is prone to foaming, glue failure, cracking, aging and the like due to moisture. At the same time, the impact resistance of the wallboard needs to be improved.
Chinese patent CN212499282U discloses a composite decorative board with wood veneer adhered on an aluminum plate, which adopts a double-layer glue layer of polyethylene glue-mixed veneer-white latex to bond the wood veneer and the aluminum plate, wherein the aluminum plate is hollow and internally provided with a reinforcing rib, and a first splicing part and a second splicing part which are respectively positioned at two sides of the aluminum plate are arranged. The decorative board that this technical scheme provided is easily assembled, and intensity is high, bonds firmly, but does not carry out treatments such as waterproof, resistant weather to the veneer.
Chinese patent CN213979554U discloses a sealed light composite wallboard, which comprises a steel frame, a rear wallboard, a front wallboard, an outer layer filling block, a protection plate, a fireproof plate and the like, and can ensure the sealing performance of the composite plate and improve the high temperature resistance of the composite plate. However, the wallboard has many layers and large density, and the internal stress can not be released in time, so that the wallboard is easy to deform, and the manufacturing process is complex.
Chinese patent CN113085285A discloses a compound fire-proof acoustic board of aluminum-wood, including substrate, first aluminum sheet layer, first wooden cortex, first specially customized glue layer, second aluminum sheet layer, second wooden cortex and second specially customized glue layer etc. the bottom of second wooden cortex is provided with bonds and has fire-proof acoustic paper. The wallboard is matched with the aluminum plate layer by utilizing the non-combustible inorganic composite board, so that the base material achieves the non-combustible effect, and the wallboard has the advantages of high strength and difficult deformation. But the wallboard does not address the handling and maintenance of the veneer.
To the problem that prior art exists, this application has provided a compound wallboard that natural veneer and aluminum honeycomb panel combine.
