Abstract
A plywood with high bonding strength comprises a panel and a core board, wherein the core board is formed by gluing at least 3 layers of wood boards and two layers of glass fiber cotton net interlayers, and the surfaces of the two wood boards which correspond to the gluing are respectively provided with a plurality of grooves and bosses which can be butted; the upper layer surface of the first layer of wood board and the lower layer surface of the last layer of wood board in the core board are respectively and correspondingly glued with one panel; the plywood has high hardness and is not easy to crack.
Description
Technical Field
The utility model belongs to the technical field of the floor substrate technique and specifically relates to a plywood of intensity is binded to height is related to.
Background
The plywood is a 3-layer or multi-layer plate-shaped material formed by rotationally cutting wood sections into single plates or slicing wood squares into thin wood and then bonding the single plates or the thin wood by using an adhesive, so that the production cost of the plywood is low and the yield is high; the core board and the face board of the traditional plywood are both wood boards, and the situations of cracking, delamination, deformation and the like often occur in the long-term use process, so that the panels cannot be used continuously;
chinese patent (CN201010133845.X) discloses an aluminum material structure multilayer composite floor and a preparation method thereof, wherein two layers of aluminum plates are arranged in the composite floor to enhance the hard strength of the composite floor, but because the aluminum plates are metal plates, when the aluminum plates and the wood plates are glued, the adhesive viscosity of the aluminum plates and the wood plates is poor, so that the composite floor is easy to crack and delaminate; in view of the above, there is a need in the market for a plywood that is relatively rigid and not prone to cracking.
Disclosure of Invention
In order to overcome not enough in the background art, the utility model discloses a plywood of high bonding strength.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a plywood with high adhesive strength comprises two face plates, a glass fiber cotton net interlayer and a core plate; the core plate is formed by splicing at least 3 layers of boards, one surface of each two adjacent boards is provided with a plurality of grooves corresponding to the two glued surfaces of the two adjacent boards, and the other surface of each two adjacent boards is provided with bosses which can be correspondingly matched with the plurality of grooves one by one;
preferably, the wood grain directions of two adjacent layers of wood boards in the core board are opposite;
preferably, the two surfaces of the other boards except the two boards at the outermost layer of the core board are provided with a plurality of grooves or bosses correspondingly matched with the grooves
Preferably, the core board is provided with 4 layers;
preferably, the thickness of the panel is 0.4-0.6 mm;
preferably, the thickness of the wood plate in the core plate is 1.6-1.8 mm;
preferably, the board of the wood board is eucalyptus or poplar.
Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has:
the utility model discloses a plywood with high bonding strength, which can improve the hardness and toughness of a core plate by clamping a glass fiber cotton net interlayer in the core plate, and is favorable for the permeation of glue and the improvement of the bonding force between the glass fiber cotton net interlayer and a wood plate because the glass fiber cotton net interlayer is made of net-shaped materials; the grooves arranged on the surfaces of the two boards can increase the contact area between the two glued boards, so that the two boards can be glued more tightly and firmly.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural diagram of the corresponding glue joint of two boards.
In the figure: 1. a panel; 2. a wood board; 3. glass fiber cotton net interlayer.
Detailed Description
The invention will be explained in more detail by the following examples, which disclose the invention and are intended to protect all technical improvements within the scope of the invention.
The plywood with high adhesive strength, which is described by combining the attached drawings 1-2, comprises two layers of panels 1, a glass wool net interlayer 3 and a core board; a multi-layer core plate is glued between the two layers of panels 1; the core board is set to be 4 layers according to requirements; a glass fiber cotton net interlayer 3 is arranged between two adjacent core plates close to the panel 1, the glass fiber cotton net interlayer 3 can share certain stress for the wood plate 2, so that the toughness of the plywood is improved, the plywood can bear larger weight, and the glass fiber cotton net interlayer 3 is made of a net material, so that the permeation of glue is facilitated, and the adhesive force between the glass fiber cotton net interlayer 3 and the wood plate 2 is improved; the core board is formed by gluing at least 3 layers of boards 2, one surface of each of two corresponding glued board surfaces of two adjacent layers of boards 2 is provided with a plurality of grooves, and the other surface of each of the two corresponding glued board surfaces of the two adjacent layers of boards 2 is provided with bosses which can be correspondingly matched with the grooves one by one, namely, the contact area between the two glued boards 2 can be increased through the butt joint of the grooves and the bosses, so that the two boards 2 are glued more tightly and firmly; according to the requirement, the two board surfaces of the other boards 2 except the two boards 2 at the outermost layer of the core board are provided with a plurality of grooves or bosses correspondingly matched with the grooves; in addition, the thickness of the panel 1 is 0.4-0.6mm, the thickness of the wood board 2 in the core board is 1.6-1.8mm, the thickness of the panel 1 is not too thick because the panel 1 mainly exists as a protection board and a decoration board of the core board, and the core board mainly plays a supporting role in the plywood, so the thicker thickness is needed to provide the supporting strength.
The part of the utility model not detailed is prior art.
