Abstract

The utility model relates to a long plant fiber wooden composite board used for a board, which comprises upper and lower skin layer woody veneers. The utility model is characterized in that a long plant fiber adhesive-bonded board is glued between the upper and the lower skin layer woody veneers. The upper skin layer is formed by gluing two-layer woody veneers. The lower skin layer is formed by gluing two-layer woody veneers. The number of the layer of the long plant fiber adhesive-bonded board can be 2 to 10 layers. The fiber directions of two contiguous long plant fiber adhesive-bonded boards are interlaced. The thickness of the woody composite board can be 12 to 70 mm. The compound board with wooden board property of the utility model has the advantages of high strength, beautiful appearance, good performance and no deformation, and can be served as a good wooden board succedaneum. Small shrubs, branches, vine class plants and sheet filament straw like vegetable can be rationally applied by the utility model, so the utility model also has wide-ranging material sources.

Description

Long string wood composite board

Technical field

The utility model relates to a kind of long string wood composite board that can be used as plank.

Background technology

Wood plank has been widely used in the various fields of industrial and agricultural production, is deficiency and the defective that remedies wood plank, and having had multiple is the composite plate of matrix with plant timber.As heavy pressing plate, block board etc., wherein heavy pressing plate is wood waste and branch etc. to be smashed back gummed compacting form, because it has destroyed the long fibre feature of plant, thereby intensity is lower, and serviceability is relatively poor; Block board is to be composited by the Wooden veneer on surface and middle plank bonding, have intensity and serviceability preferably, but it still need consume a large amount of wood planks, and its material source will be restricted.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art and provide a kind of material source wide, the more excellent long string wood composite board of serviceability.

The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include the Wooden veneer on upper and lower top layer 2,3, its difference is to be bonded with between the upper and lower surface wood veneer long string glued board 1.

Press such scheme, described upper epidermis 2 is bonded by two-layer Wooden veneer, following top layer 3 is bonded by two-layer Wooden veneer, described long string glued board 1 can be 2～10 layers, be generally 3～7 layers, every layer thickness is 4～10mm, and the machine direction of adjacent two long string glued boards is interlaced, and it is superimposed to be generally the vertical interlaced position; The thickness of wood composite board can be 12～70mm.

Described long string glued board as base material, is got in them one or more by various undershrubs and branch, vine plant, sheet long fibre grass crop, forms through rolling-alignment-oven dry-impregnation-compacting.

The beneficial effects of the utility model are: 1, intermediate course adopts long string glued board, and each plate machine direction is staggered superimposed, the sheet material that is combined into not only intensity is higher, and outer surface is attractive in appearance, serviceability is good, characteristic with wood plank, not yielding, can be used as a kind of good wood plank substitute; 2, make various undershrubs, branch, vine plant, sheet long fibre straw or like vegetable obtain more reasonably using, also make the utility model possess material source widely simultaneously.

Description of drawings

Fig. 1 is the profile of an embodiment of the utility model.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing, upper epidermis 2 and following top layer 3 are bonded by two-layer Wooden veneer, wherein outermost Wooden veneer is a whole type, there is wood grain on the surface, last, be bonded with 3～7 layers long string glued boards 1 between the following top layer, be generally 3 or 5 or 7 layers, the string direction of every layer of glued board is staggered, staggered orientation can become 90 °, and promptly perpendicular staggered, promptly the glued board string direction of ground floor is vertical, the glued board string direction of the second layer is horizontal, by that analogy, the long string glued board of each layer and last, following top layer is by adhesive, repressed being composited.Described long string glued board is formed through rolling-alignment-oven dry-impregnation-compacting by various undershrubs and branch.

Claims

1, a kind of long string wood composite board includes the Wooden veneer on upper and lower top layer, it is characterized in that being bonded with between the upper and lower surface wood veneer long string glued board.

2, by the described composite plate of claim 1, it is characterized in that described upper epidermis is bonded by two-layer Wooden veneer, following top layer is bonded by two-layer Wooden veneer.

3, by claim 1 or 2 described composite plates, it is characterized in that described long string glued board can be 2～10 layers.

4, by the described composite plate of claim 3, it is characterized in that described long string offset plate is 3～7 layers, every layer thickness is 4～10mm, and the machine direction of adjacent two long string glued boards is interlaced.
