Abstract

The utility model discloses a bamboo and wood artificial plate with an overlapped structure, which is composed of a core layer, a wood thin plate, and paper for impregnating macromolecular resin. The core layer is a structure layer which is formed by the overlapping of bamboo sheet layer and a wood sheet layer. The utility model overcomes the defects that the core layer of the existing artificial plate is formed by the overlapping of bamboo sheets and wood sheets, so the core layer has the disadvantages of no levelling, non-uniform thickness, leakiness, etc. The utility model is suitable for construction mould plates, packaging box plates, floors, and other decoration panels.

Description

A kind of bamboo wood artificial board

The utility model belongs to artificial board, is meant the artificial bamboo wood board of laminated construction especially.

The various artificial boards that form through the splicing pressurization as sandwich layer with bamboo matter offset plate are arranged in the market, this bamboo matter central layer is generally bamboo chip and bamboo chip is crisscross laminates, because the bamboo chip thickness that bamboo wood is harder and process without selection does not wait, plate after the extrusion forming is smooth inadequately, the even height fluctuation of became uneven can occur, has influenced result of use, and the sandwich layer bamboo chip each other and exist the slit between the levels, cause water easily to infiltrate, influence its fastness, easily produce and come unstuck.

The purpose of this utility model provides the surfacing that a kind of sandwich layer is overlapped and formed by bamboo chip layer and wood chip layer, and thickness evenly and reduced the bamboo wood artificial board material in slit.

Bamboo wood artificial board of the present utility model, paper by sandwich layer, wooden thin plate and dipping macromolecule resin constitutes, described wooden thin plate is overlying on sandwich layer, and up and down two surfaces and its machine direction and core layer surface machine direction are perpendicular, the paper of dipping macromolecule resin then is overlying on wooden thin sheet surface, sandwich layer is overlapped successively by bamboo chip layer and wood chip layer and forms, every layer is not limited to a slice, promptly can be that multilayer is with the material sheet material, this core structure, because it is wooden softer, easy and bamboo chip layer formation compact structure has reduced the slit effectively after the press compacting, has guaranteed flatness.

Described bamboo wood artificial board, sandwich layer comprise three layers of wood chip layer and two layers of bamboo chip layer, make bamboo chip layer two sides that the wood chip layer all be arranged, and this helps reducing between bamboo chip the slit and improves flatness.

Described bamboo wood artificial board, bamboo chip layer are arranged in parallel successively by the bamboo chip of uniform thickness and form, and the sandwich layer after selection processing can guarantee that thickness is even.

Described bamboo wood artificial board, bonding between bamboo chip layer and wood chip layer, bamboo chip layer bamboo chip and bamboo chip by macromolecule resin.

This bamboo wood artificial board has improved core structure, is keeping sufficient intensity simultaneously, has improved flatness, the packing of plate, the uniformity of thickness, is difficult for coming unstuck, and can be used as the construction template, packaging boxboard, floor and other decoration panel.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A partial enlarged drawing of Fig. 1.

Be described further below by embodiment and accompanying drawing thereof, as shown in the figure, bamboo wood artificial board of the present utility model, its sandwich layer (1) is overlapped with wood chip layer (5) by bamboo chip layer (4) and forms, every layer is not limited to a slice, promptly can be that multilayer is with the material sheet material, bamboo chip layer (4) can be woven into bamboo curtain splint with bamboo strip, also can be arranged in parallel successively and form by the bamboo chip of uniform thickness, this sandwich layer (1) surface is respectively coated with the wooden thin plate (rotary cut venner) (2) of drying, cover the paper (3) that has flooded macromolecule resin more than one deck on the wooden thin plate (2) again, make the machine direction on the machine direction of wooden thin plate (2) and sandwich layer (1) surface perpendicular during assembly, during extrusion forming, form the wood chip layer (5) of sandwich layer (1) because material is softer, after the press extrusion, can produce certain deformation, with closely knit combination of bamboo chip layer (4), reduced the slit between bamboo chip layer (4) bamboo chip and the bamboo chip, made it to combine together substantially.

Claims

1, a kind of bamboo wood artificial board, paper (3) by sandwich layer (1), wooden thin plate (2) and dipping macromolecule resin constitutes, described wooden thin plate (2) is overlying on sandwich layer (1), and two surfaces and its machine direction and core layer surface machine direction are perpendicular up and down, the paper (3) of dipping macromolecule resin then is overlying on wooden thin plate (2) surface, it is characterized in that sandwich layer (1) is overlapped successively by bamboo chip layer (4) and wood chip layer (5) to form.

2, bamboo wood artificial board as claimed in claim 1 is characterized in that sandwich layer (1) comprises three layers of wood chip layer and two layers of bamboo chip layer, makes bamboo chip layer two sides that the wood chip layer all be arranged.

3, bamboo wood artificial board as claimed in claim 1 is characterized in that bamboo chip layer (4) is arranged in parallel successively by the bamboo chip of uniform thickness to form.
