Abstract

The utility model relates to a decorative wooden board of a bamboo-wood composite structure, which is composed of an upper and a lower bamboo splicing plates, a solid wood splicing plate and a resin layer which is used for splicing the space between every two plates. The bamboo splicing plates are composed of a plurality of bamboo splints which are mutually connected, wherein the resin layer is used for gluing the space between every two splicing side faces of the bamboo splints, and the abutting end of each of the bamboo splints in a length direction is also glued by the resin layer; the solid wood splicing plate is formed by splicing and butt jointing a plurality of solid wood splints, wherein the resin layer is used for gluing the space between every two splicing side faces of the solid wood splints and the abutting end of each of the solid wood splints in a length direction is also glued by the resin layer. Thereby, the bending strength of the utility model achieves more than 5MPa, free formaldehyde is not freed when the utility model is used, therefore the utility model can not cause the pollution of the indoor air.

Description

The decoration wood based panel of composite bamboo-timber structure

Technical field

The utility model relates to a kind of decoration wood based panel of composite bamboo-timber structure.

Background technology

As everyone knows, bamboo wood is the second largest forest reserves of China, the fast growth of bamboo wood, and physical and mechanical property is good, and the texture gracefulness is attractive in appearance.Adopt sheet material and other ornament materials of bamboo processing to obtain being extensive use of in building decoration finishing field.On the other hand, China's Forest Resources is fewer and feweri, has carried out the transition to gradually at present based on a large amount of employing fast-growing, high-yield woods timber resources.Though fast-growing, high-yield woods timber has the characteristics of fast growth, material is relatively poor.Therefore develop bamboo wood joint product, performance bamboo wood and timber is characteristic separately, make its have higher added value and widely the scope of application become the focus of present product development and application.

At present, main bamboo wood joint product mainly contains following a few class: the one, and utilize dwarf bamboo to be primary raw material, it is pulverized discongest after-applied adhesive as sandwich layer, as the top layer bamboo wood joint product that is composited, the main target product is used for the architectural engineering cement formwork with wood single-plate; Second class is to be dash board with the bamboo edge-gluing veneer, is central layer with wood single-plate or solid wood bar, presses texture alternate directions gummed back and uses, and mainly uses the floor series products; The 3rd class is to be sheet surface layer with bamboo mat or bamboo curtain splint, is the bamboo wood composite container flooring product that middle layer plate is produced with the veneer.Above-mentioned bamboo wood joint product has mainly been emphasized bamboo wood as the characteristics of reinforcing material or specially as the characteristics of ornament materials, and the characteristics with ornament materials and structural material do not combine.

Summary of the invention

The purpose of this utility model provides a kind of decoration wood based panel of composite bamboo-timber structure, be a upper and lower bamboo jigsaw and a middle solid wood jigsaw, with each plate of resin bed bonding (spraying), and the splicing of each bamboo jigsaw, solid wood jigsaw itself or butt joint also are bonding with resin bed, thereby constitute the decoration wood based panel that has structural wood concurrently and decorate the material characteristics.

The utility model provides a kind of decoration wood based panel of composite bamboo-timber structure, form by the resin bed between upper and lower two bamboo jigsaw, a solid wood jigsaw and bonding each plate, this bamboo jigsaw is to be formed by connecting by many bamboo bars, wherein bonding between the splicing side of each bamboo bar with resin bed, and the butt end of each bamboo bar length direction is also bonding with resin bed, equally, this solid wood jigsaw is to be formed by many solid wood bar splicings and butt joint, wherein bonding between the splicing side of each solid wood bar with resin bed, and the butt end of each solid wood bar length direction is also bonding with resin bed.

The utility model provides a kind of decoration wood based panel of composite bamboo-timber structure, and above-mentioned bamboo jigsaw is a multilayer, and between each layer folder to establish resin bed bonding, above-mentioned solid wood jigsaw is a multilayer, and presss from both sides between each layer that to establish resin bed bonding.

The utility model provides a kind of decoration wood based panel of composite bamboo-timber structure, and above-mentioned resin bed is Lauxite or integrated timber two component adhesive or isocyanate resin or melamine modified urea-formaldehyde resin.

Bending strength of the present utility model reaches more than the 5MPa, in addition, adopts the sheet material of this kind method gummed in use not have free formaldehyde to discharge, and can not pollute room air.

The specific embodiment

The utility model is made up of the resin bed 3 between two bamboo jigsaw 1, a solid wood jigsaw 2 and bonding each plate, as shown in Figure 1, 2, and wherein:

Bamboo jigsaw 1 is to be formed by 11 splicings of many bamboo bars and butt joint, wherein bonding between the splicing side 111 of each bamboo bar 11 with resin bed 3, and the butt end 112 of each bamboo bar 11 length direction is also bonding with resin bed 3, and above-mentioned butt end 112 can be termination or finger, shown in Fig. 3,4.This bamboo jigsaw 1 uses as upper and lower dash board, and these bamboo bar 11 thickness ranges are at 2mm～5mm; Width range is at 10mm～30mm; Length range is not limit.Adopt this bamboo bar 11 can splice the bamboo jigsaw 1 of any length and width, its bamboo jigsaw 1 can be multilayer (resin bed 3 of also spraying between multilayer) again, and its texture is rift grain direction gummed.

Solid wood jigsaw 2 is to be formed by 21 splicings of many solid wood bars and butt joint, wherein bonding between the splicing side 211 of each solid wood bar 21 with resin bed 3, and the butt end 212 of each solid wood bar 21 length direction is also bonding with resin bed 3, and above-mentioned butt end 212 can be termination or finger, shown in Fig. 3,4.This bamboo jigsaw uses as central layer, and these solid wood bar 21 thickness ranges are at 2mm～30mm; Width range is at 20mm～40mm; Length range is not limit.Adopt this kind solid wood bar 21 can splice the solid wood jigsaw 2 of any length and width, its solid wood jigsaw 2 also can be multilayer (resin bed 3 of also spraying between multilayer), and texture is rift grain direction gummed.

Two bamboo jigsaw 1 are respectively as upper and lower dash board, and solid wood jigsaw 2 is as central layer, bonding with resin bed 3 between bamboo jigsaw 1 and solid wood jigsaw 2, this resin bed 3 can be that Lauxite, integrated timber can be to spray or brush to form with two component adhesive, isocyanate resin or melamine modified urea-formaldehyde resin, resin bed.

All are rift grain direction combination by the compound mode that cementing layer is between bamboo clappers and the plank, form a kind of lightweight construction sheet material through hot-press gluing.This kind sheet material promptly has the performance indications of structural wood, has the characteristics of ornament materials again, can be widely used in building decoration and fitment and structural material.

The utility model can be that the bending strength of bamboo-wood composite material reaches more than the 5MPa, adopt the bonding strength of this kind method institute sheet can reach the requirement of the standard of " laminated structure " standard GB 50206-2002 and outdoor use structural plywood, in addition, adopt the sheet material of this kind method gummed in use not have free formaldehyde to discharge, can not pollute room air.
