Abstract

The utility model provides a flexible decorative veneer. The flexible decorative veneer is good in antiflaming performance and can be shaped at great bending angles. The flexible decorative veneer is of a multi-layer structure, the surface layer is a veneer layer, the middle layer is a metal film, and the bottom layer is kraft paper; a non-woven fabric layer is arranged between the surface layer and the middle layer, and between every two neighboring layers is provided with an adhesive layer or an adhesive film layer. According to the flexible decorative veneer, the non-woven fabric layer plays a role of avoiding damage or tearing of the veneer and providing the veneer with high flexibility and high stability, so that when being manufactured into various products through machines, the veneer can avoid problems. The flexible decorative veneer can be adhered to surfaces of any curvatures of furniture and avoid breakage of wood pieces, thereby not only saving large amounts of wood, but also being convenient and time-saving and further reducing the cost.

Description

A kind of flexible wooden skin of decorating

Technical field

The utility model relates to a kind of wooden skin of decorating, and relates in particular to the bent flexibility of a kind of flexibility and decorates wooden skin.

Background technology

Wood skin refers to the laminar wood materials that flitch obtains through slicing or rotary-cut, generally for the manufacture of top-grade furniture, solid wooden compound floor, high-grade timber and thick china.Because wooden skin has retained the advantage of natural timber completely, the sensation of building solid wood, has saved in a large number natural timber resource simultaneously, has effectively reduced the manufacturing cost of product, is therefore subject to manufacturer and users' extensive welcome, has wide market prospects.But wooden skin product has inflammable frangible shortcoming, a large amount of uses at indoor decorating especially public place are larger threats to people's life security, simultaneously wooden skin product is more crisp, cannot wide-angle bending have hindered the further application of wooden skin product.Patent No. CN202476996U discloses a kind of pachydermia wood leather strap, it is bonding by the stack of delta wood cortex, make thickness thicker, can carry out the chamfered after edge sealing to furniture or class woodwork, but it still can't resolve technical problem that cannot wide-angle bending-wood skin, is not also considered how fire-retardant wooden skin is.

Summary of the invention

The purpose of this utility model is to provide a kind of fire resistance flexibility good, can wide-angle bending moulding to decorate wooden skin product.

For achieving the above object, the utility model by the following technical solutions: a kind of flexible wooden skin of decorating, adopts sandwich construction, surface layer is wooden cortex, and intermediate layer is metallic film, and bottom is brown paper, between surface layer and intermediate layer, being nonwoven layer, is adhesive layer or glued membrane ply of paper between layers.

Preferred as one, the upper surface of surface layer wood cortex is provided with skin of paint, on wooden cortex, scribbles after paint, makes wooden skin surface-stable, and energy and water isolation, there will not be wooden skin to be dried the situation of after-contraction.

Preferred as one, in nonwoven layer, in the machine direction of nonwoven and wooden cortex, the machine direction of wooden skin is perpendicular.

Preferred as one, in described nonwoven layer, nonwoven is impregnation nonwoven.Owing to having adopted impregnation adhesive-bonded fabric, bondline thickness can significantly reduce, even can form discontinuous glue-line, portioned product mesoglea can no longer take thickness in theory, significantly reduce the thickness of soft composite veneer, in the situation that intensity improves, thickness increases limited, and this is a prerequisite that keeps suppleness.

Preferred as one, described wooden cortex is natural veneer or recombinant decorative wood skin.

Preferred as one, described nonwoven layer and wooden cortex gross thickness are 0.05mm-0.6mm.

Preferred as one, described metallic film is aluminium foil or tinfoil paper, thickness 0.01mm-0.08mm.

Preferred as one, the grammes per square metre of described brown paper is 40-100g/m ².

Preferred as one, the top of surface layer wood cortex also comprises difficulty combustion layer, and difficult combustion layer is to be set to the difficulty combustion layer that the surface of melamine impregnated paper adds alundum (Al2O3).

The beneficial effects of the utility model are: the utility model, take metallic film as isolated material, utilizes the noninflammability of metallic film to give wooden skin fire resistance, and metallic film also plays humidification, have overcome that wooden leather material is frangible, frangibility, defect easy to crack.Described wooden skin also can do flame retardant solution dipping, brushing or spray and process, to improve flame retardant rating.After testing, flexible fire resistance of decorating wooden skin described in the utility model can reach the A of GB GB/T 8624-2012 regulation ₂level or B level.

In addition, the effect of the utility model nonwoven is avoid wooden skin damage or tear, and this wooden leatherware with nonwoven has very large suppleness and stability, makes wooden skin in the time that other machines is produced into different goods, is not easy to have problems.Can be attached at the surface of any curvature of furniture, and can not make wood chip fracture, both save a large amount of timber, process convenient and time-saving again, thereby reduced cost.Nonwoven is located between wooden cortex and metallic film, makes multi-layer sheet easy to manufacture, and the bond properties of nonwoven and each interlayer is good.And wooden cortex is after strengthening with nonwoven laminating, easily, intensity and good toughness, can not tear part in carrying.

And, the machine direction of the utility model nonwoven and the machine direction of wooden skin are perpendicular, the composite that has adopted machine direction to intersect, guarantee that composite veneer has good tensile strength two-way, and wooden skin and nonwoven adhesion strength high, quality softness, easy to use, low cost of manufacture, no matter tractive can not be separated from each other and be broken, can be applicable to the decorative faced use of various shapes in any direction.

The wooden skin multi-layered product of the flexible decoration of the utility model, can bending do moulding, and plasticity is strong.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment.

1-wood cortex, 2-nonwoven layer, 3-adhesive layer, 4-metallic film, 5-brown paper in figure.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model embodiment is described further.

As shown in Figure 1, the wooden skin of the flexible decoration of the utility model embodiment, adopts sandwich construction, and surface layer is wooden cortex 1, and intermediate layer is metallic film 4, and bottom is brown paper 5, is nonwoven layer 2 between surface layer and intermediate layer, is polyurethane adhesive layer 3 between layers.

Wherein, the upper surface of surface layer wood cortex can also be provided with skin of paint, on wooden cortex, scribbles after paint, makes wooden skin surface-stable, and energy and water isolation, there will not be wooden skin to be dried the situation of after-contraction.

In described nonwoven layer, in the machine direction of nonwoven and wooden cortex, the machine direction of wooden skin is perpendicular.

Described wooden cortex is natural veneer or recombinant decorative wood skin.

Described nonwoven layer and wooden cortex gross thickness are 0.05mm-0.6mm.

Described metallic film is aluminium foil or tinfoil paper, thickness 0.01mm-0.08mm.

The grammes per square metre of described brown paper is 40-100g/m ².

In Fig. 1, adhesive layer 3 has formed one deck, also can not form one deck, as adopted impregnation nonwoven to replace the nonwoven layer 2 in Fig. 1, from technological angle, the uniformity of impregnation easily guarantees, simultaneously, also for continuous productive process provides reasonable basis, high more a lot of than the efficiency of artificial brushing.Meanwhile, in the situation that glue consumption reduces, fugitive constituent also can significantly reduce, and this is current to ornament materials important requirement, environmentally friendly better.
