Description

composite sheet

technical field

The utility model relates to board materials, in particular to a composite board material with low cost, good toughness, unbreakable properties, high bearing capacity and great nail adhesion.

Background technique

Traditional door panels and furniture panels are generally made of two solid wood panels fixed on a wooden frame. The cost of using solid wood panels to make door panels or furniture panels is relatively high. In addition, with the strengthening of environmental protection, the price of wood continues to rise. High, so the cost of traditional solid wood panels to make door panels or furniture is getting higher and higher; now medium-density or high-density fiberboards are also used instead of solid wood panels, but fiberboards are not tough enough compared to solid wood, and are prone to breakage or deformation. Long-term use is easy to rot, and The load-bearing is small, and when the fiberboard is broken, more short fibers will be produced, which makes people mistake it for cardboard, and the nails on the fiberboard are also difficult to attach firmly.

Utility model content

In order to overcome the disadvantages of the prior art, the purpose of the utility model is to provide a composite plate with low cost, good toughness, unbreakable, high load-bearing and strong nail adhesion.

The utility model is realized through the following technical measures. A composite board includes a board frame and two-layer composite boards respectively attached to two sides of the board frame; A plurality of horizontal strips vertically arranged; the composite board includes a core board, a face plate and a back board, the core board includes at least one layer of solid wood veneer or bamboo wood veneer, and the face plate and the back board are fiberboards. Adhesive layers are arranged between adjacent boards.

As a preferred manner, the vertical wood strips and horizontal wood strips are solid wood strips, laminated lumber or laminated veneer lumber.

As a preferred manner, the core board includes two layers of solid wood veneer or bamboo wood veneer.

As a preferred manner, the solid wood veneer or bamboo wood veneer has a thickness of 1-3 mm.

As a preferred manner, the thickness of the fiberboard is 1-1.5 mm.

As a preferred manner, the fiberboard is a high-density board.

As a preferred manner, the core board is composed of two layers of solid wood veneer or bamboo wood veneer and a layer of fiberboard sandwiched between the two layers of solid wood veneer or bamboo wood veneer.

As a preferred manner, it also includes at least one layer of flame-retardant board arranged in the face plate and the back plate.

As a preferred manner, the flame-retardant board is a fiberboard with small holes, and the small holes are filled with ammonium phosphate dry powder.

As a preferred manner, the composite panel is a door panel, a partition panel or a decorative panel.

The core board of the composite board in the utility model has at least one layer of solid wood veneer or bamboo wood veneer, and the face plate and the back board are all fiber boards, thereby reducing the cost of the product while strengthening the product strength, because the core board has at least one layer Solid wood veneer or bamboo wood veneer, so the utility model is low in cost, good in toughness, not easy to break, high in load bearing and strong in nail adhesion.

detailed description

Below in conjunction with embodiment and with reference to accompanying drawing, the utility model is described in further detail.

A kind of composite board, referring to Fig. 1 to Fig. 5, comprises a board frame and two-layer composite boards 1 attached to the two sides of the board frame; Three horizontal solid wood strips 3 vertically arranged; the composite board 1 includes a core board, a face plate 100 and a back board 200, the core board includes at least one layer of solid wood veneer or bamboo wood veneer, the face plate 100 and the back board 300 They are all fiber boards, and a glue layer is arranged between adjacent boards. In other embodiments, the vertical wooden strips and horizontal wooden strips can also be spliced by laminated veneer lumber, glulam or solid wood.

The core board of the composite board in the composite board has at least one layer of solid wood veneer or bamboo wood veneer, and the face plate 100 and the back board 300 are all fiberboards, thereby reducing the cost of the product while strengthening the product strength, because the core board is at least There is a layer of solid wood veneer or bamboo wood veneer, so the composite board is low in cost, good in toughness, not easy to break, high in load bearing and strong in nail adhesion. The composite board can be made into a door board, a partition board or a decorative board.

In the composite board of Example 1, please refer to Fig. 3, on the basis of the previous technical solution, it can also be that the core board is a layer of solid wood veneer 200, and in other embodiments, it can also be a layer of bamboo wood veneer .

In the composite board of Example 1, please refer to FIG. 3 , on the basis of the previous technical solution, it may also specifically be that the thickness of the solid wood veneer 200 is 1-3 mm.

In the composite board of Example 1, please refer to FIG. 3 , on the basis of the previous technical solution, it can also be specifically that the face plate 100 and the back plate 300 are high-density boards with a thickness of 1-1.5mm.

In the thicker composite board in Embodiment 2, please refer to Fig. 4, on the basis of the previous technical solution, it can also be that the core board is composed of two layers of solid wood veneers 400 and 600 and a layer between them Fiberboard 500, and the solid wood veneer can also be bamboo veneer.

In the composite board of Example 3, please refer to Fig. 5, on the basis of the previous technical solution, it can also specifically include a layer of flame-retardant board 700 arranged on the bottom surface of the panel 100, and the core board is a two-layer solid wood veneer 800 , 900. A layer of flame retardant board 700 is arranged on the bottom surface of the panel 100, so that when a fire occurs, the flame retardant board 700 is used to prevent the fire from spreading.

In the composite sheet of Example 3, please refer to Fig. 5. On the basis of the previous technical solution, the flame-retardant board 700 can also be a fiberboard with small holes 702, and the small holes 702 are filled with ammonium phosphate Dry powder 701. The ammonium dihydrogen phosphate in the ammonium phosphate dry powder 701 can absorb heat and decompose into ammonia and phosphoric acid in the combustion flame, and then generate P ₂ O ₅ . Each step of the reaction is an endothermic reaction, so it has a better cooling effect; the free ammonia generated by the decomposition can react with the OH free radicals generated in the flame combustion reaction, reduce and terminate the free radicals generated by the combustion reaction, and reduce the combustion reaction rate. , when the concentration of free ammonia in the flame is high enough, the contact area with the flame is large enough, the rate of free radical termination is greater than the rate of combustion reaction generation, the chain combustion reaction is terminated, and the flame is extinguished. In addition, ammonium dihydrogen phosphate decomposes at high temperature, forming a layer of glass-like film on the surface of solid matter. The residual covering covers the surface of the burning object. After cooling, a brittle covering is formed to isolate the burning surface from the air. When the covering reaches a certain thickness, it can Prevent re-ignition and prevent combustion from proceeding.

The above is the clarification of the composite plate of the present utility model, which is used to help understand the utility model, but the implementation of the utility model is not limited by the above examples, and any changes, modifications, and substitutions made without departing from the principle of the utility model , combination, and simplification, all should be equivalent replacement methods, and are all included in the protection scope of the present utility model.
