Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below.
An embodiment of the present invention provides a metal-wood composite board, as shown in fig. 1 and 3, including: a plurality of metal plate layers 1 and wood plate layers 2 which are adhered by an adhesive and are alternately arranged up and down. The first layer and the last layer of the metal wood composite board are both wood board layers 2; the upper and lower surfaces of the metal plate layer 1 are processed with wire-drawing textures, and the metal plate layer 1 is processed with holes 101 arranged dispersedly.
The metal-wood composite board provided by the embodiment of the utility model is formed by combining a plurality of metal board layers 1 and wood board layers 2 which are adhered by an adhesive and are alternately arranged up and down, the wood board layers 2 keep the characteristics of nature and environmental protection, and the metal board layers 1 provide higher strength and support, so that the metal-wood composite board can meet the requirement of high strength. The first layer and the last layer of the metal wood composite board are both wood board layers 2, so that the whole composite board still keeps the texture of wood in appearance and is more attractive. The wire drawing textures processed on the upper and lower surfaces of the metal plate layer 1 can improve the roughness of the upper and lower surfaces of the metal plate layer 1, so that the combination between the metal plate layer 1 and the wood plate layer 2 is firmer. Meanwhile, the holes 101 distributed on the metal plate layer 1 can reduce the stress of the metal plate layer 1, so that the whole plate is prevented from being bent when a large-size composite plate is processed, the residual metal material after punching can be recycled, the material is saved, and the cost is reduced. Therefore, the metal wood composite board provided by the embodiment of the utility model has high bonding strength, is not easy to bend and deform, and is suitable for large-scale popularization and application.
Specifically, the metal-wood composite board provided by the embodiment of the utility model utilizes the combination of metal and wood, exerts the advantage of high metal strength, improves the strength of the composite board, meets higher strength requirements with less materials, and saves resources. The metal plate layer 1 is made of metal with lower density and higher hardness, and preferably an aluminum plate layer, a copper plate layer or a stainless steel plate layer. The metal wood composite board made of the metal board layer 1 is high in strength, flat and not prone to bending, and compared with honeycomb metal wood composite boards on the market, the metal wood composite board is more suitable for manufacturing door boards, partition boards and the like. The metal plate layer 1 can be a whole metal plate or a metal buckle plate, and the metal buckle plate can make the metal wood composite plate more portable. In addition, the edge of the metal-wood composite board does not need to be sealed, the metal board layers 1 and the wood board layers 2 which are alternately arranged are more attractive when seen from the side, and the real internal structure is more relieved for customers.
In order to make the structure of the metal wood composite board more uniform and the stress is balanced, the metal board layer 1 and the wood board layer 2 are symmetrical up and down along the thickness direction of the metal wood composite board. As shown in fig. 1, the metal plate layers 1 have the same thickness, the wood plate layers 2 have the same thickness, and the first layer and the last layer are both the wood plate layers 2, so that the metal wood composite plate is vertically symmetrical along the thickness direction. According to actual demand, the thickness of each wood board layer 2 also can be inconsistent, as shown in figure 2, in order to improve the proportion of wooden structure, the advantage of the natural environmental protection of wood board layer 2 is fully played, the thickness of middle wood board layer 2 can be increased, the metal board layer 1 connected from top to bottom with it plays the effect of strengthening rib, improves the bulk strength of metal wood composite board, and the wood board layer 2 of first layer and last layer plays the effect of veneer decoration. On the basis of the structure shown in the attached drawing 1, the metal wood composite board is adjusted according to the actual application requirements, but the metal wood composite board still can meet the requirement that the metal board layer 1 and the wood board layer 2 are vertically symmetrical along the thickness direction of the metal wood composite board, so that the overall structure of the metal wood composite board is uniform and symmetrical, and the defects that the whole metal wood composite board is stressed unevenly and has bending deformation and the like due to vertical asymmetry in the thickness are avoided.
It can be understood that the metal plate layer 1 mainly plays a role in improving the strength of the board, and the main body of the metal wood composite board is also the wood plate layer 2, so that the thickness of the metal plate layer 1 is less than that of the wood plate layer 2, the thickness of each metal plate layer 1 is equal and is 0.3-10mm, and the thickness of each wood plate layer 2 is equal and is 2-10 mm. The thickness of the metal plate layer 1 affects not only the strength of the metal wood composite panel but also its density. If the metal plate layer 1 is too thick, although the strength of the metal wood composite plate can be increased, the weight of the metal wood composite plate is too large under the same volume, so that the furniture is too heavy and inconvenient to use. If the metal plate layer 1 is too thin, the requirement for improving the strength of the metal wood composite plate cannot be met. Therefore, the thickness of the metal plate layer 1 is preferably 0.3 to 10mm, for example, 0.3mm, 2.5mm, 5mm, 7.5mm, 10mm, or the like. The thickness of the wood veneer layer 2 is generally larger than that of the metal veneer layer 1 so that the ratio of metal to wood in the metal-wood composite panel is appropriate, and the thickness of the wood veneer layer 2 is preferably 2 to 10mm, for example, 2mm, 3.5mm, 6mm, 8.5mm, 10mm, etc. The thicknesses of each metal plate layer 1 and each wood plate layer 2 are respectively equal, so that the processing process is more convenient, and the combination between the plate layers is more flexible.
In order to improve the roughness of the metal ply 1, the depth of the wire-drawing texture on the upper and lower surfaces of the metal ply 1 is 0.02 to 0.1mm, so that the wood ply 2 and the metal ply 1 are more firmly bonded. The metal plate layer 1 and the wood plate layer 2 are bonded by using the adhesive only, so that the bonding is not firm enough, and the whole looseness is easy to occur. After the upper surface and the lower surface of the metal plate layer 1 are uneven through a wire drawing process, the metal plate layer 1 and the wood plate layer 2 are embedded deeper, and after the connection through the adhesive, the plate layers made of two materials are combined more firmly. Wire drawing is a common method for surface treatment, and the depth of wire drawing treatment performed on the upper and lower surfaces of the metal clad layer 1 by a wire drawing machine is preferably 0.02 to 0.1mm, for example, 0.02mm, 0.05mm, 0.07mm, 0.08mm, 0.1mm, or the like, in order to ensure that the strength of the metal clad layer 1 itself is not affected.
It should be noted that the effect of improving the surface roughness of the metal panel layer 1 can be achieved by other surface treatment methods, for example, the surface of the metal panel layer 1 is roughened with 40 to 60-mesh abrasive cloth so that the surface roughness of the metal panel layer 1 becomes Ra60, and the degree of firmness of the bonding of the wood panel layer 2 and the metal panel layer 1 can be improved. However, if the surface of the metal plate layer 1 is treated by sand blasting, the produced metal wood composite plate is easy to deform, so that the metal plate layer 1 is not suitable to be treated by sand blasting.
In order to reduce the stress in the metal plate layer 1, holes 101 are formed in the metal plate layer 1 in a distributed manner, and the holes 101 are circular, rectangular or star-shaped. The circular holes 101 are most convenient to process, the distances among the holes 101 are equal, the stress in the metal plate layer 1 can be reduced to the greatest extent, and the phenomenon that the whole metal plate layer 1 is bent and deformed in a large size is avoided. In addition, the residual metal materials after the hole 101 is processed can be recycled, so that the manufacturing cost of the metal wood composite plate is greatly reduced. E.g. 1m 1mm thick2The back area of the metal plate after punching can be reduced to 50%, and the cost is reduced by more than 40%. Meanwhile, the reasonable punching does not affect the strength of the metal plate layer 1, namely, a better effect is achieved with lower cost.
Specifically, as shown in fig. 3, in order to ensure that the stress at each position of the metal plate layer 1 is uniform, the holes 101 on the metal plate layer 1 are uniformly arranged in a matrix, and the distance d between the holes at the edge and the edge of the metal plate layer is the same as the distance d between the holes at the edge and the edge of the metal plate layer1Greater than 10 mm. On the basis of ensuring the strength of the metal plate layer 1, holes 101 can be arranged as many as possible. But the distance d between the edge-most hole and the edge of the metal plate layer1At least 10mm, for example, at a distance of 10mm, 15mm, 20mm, 30mm, 40mm, etc., to avoid the edge strength of the sheet metal layer 1 from being affected.
Too large holes 101 or too small holes 101 in the metal plate layer 1 may affect the strength of the metal plate layer 1, and too small holes 101 or too large holes 101 may result in higher cost of the metal plate layer 1. Specifically, the holes on the metal plate layer 1 may be circular, rectangular, or star-shaped. When the holes are circular, the diameter d2 of the circle is 3-20mm, for example 3mm, 8mm, 12mm, 16mm, 20mm, etc. When the holes are rectangular or star-shaped, the area of the rectangular or star-shaped holes is larger than 2mm multiplied by 2 mm. Spacing between holesd3Is 2-70 mm. At the same time, the appropriate hole spacing d3And the large-breadth plate can be conveniently cut into small plates for manufacturing furniture.
At present, the strength of the honeycomb metal composite board on the market is only 60-70% of that of the wood board, and is only 20% of that of the metal wood composite board provided by the embodiment of the utility model, and because the honeycomb metal has a certain thickness, a thinner board cannot be manufactured, the surface of the honeycomb metal board can only be pasted with wood skin with the thickness of 0.5mm, and the wood accounts for a small amount in the whole board. In contrast, the metal-wood composite board provided by the embodiment of the utility model has higher strength, and the strength of the metal-wood composite board with the thickness of 12mm (for example, two metal plate layers 1 are matched with three wood plate layers 2) is equivalent to that of a splint with the thickness of 30mm, so that the quality is excellent. And the metal plate layer 1 and the wood plate layer 2 are flexibly combined, the thickness of the surface layer wood plate can reach 2-5mm, and more real wood texture is provided for people. The metal wood composite board provided by the embodiment of the utility model can be made into a large-width board with the thickness of 4-50mm and the thickness of 3600mm multiplied by 1200mm, can ensure that the surface of the board is flat and has no bending deformation, and has stronger universality for furniture manufacture.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
