Abstract

The invention provides a composite decorative board. A multi-layer structure is adopted, a surface layer is a wood veneer layer, a middle layer is a metal thin film, a bottom layer is an inorganic material layer, and a tackiness agent layer or a film adhesive layer is arranged between every two layers. The inorganic material layer is arranged in the decorative board, the decorative board can reach a non-combustible level, the proportion of a fireproof material can reach 90 percent, the composite decorative board has the excellent fireproof and flame-retardant property, and the application occasion can be further expanded. In addition, the surface layer, namely the wood veneer layer, can be isolated from the inorganic materials on the bottom layer and the exterior air through a paint layer on the surface layer and the metal thin film layer below the surface layer, and therefore the composite decorative board is in the relative stable state.

Description

A kind of composite decorating board

Technical field

The present invention relates to a kind of composite decorating board, belong to architectural decoration material field.

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, be a larger threat in a large amount of uses of indoor decorating especially public place to people's life security.

Inorganic material for example calcium silicate board because it has good fireproof performance, intensity advantages of higher, people also apply it in ornament materials, the disclosed a kind of composite plate of for example patent No. 200320119793.6, it comprises backing material plate (1), adhesive-layer (2), decoration panel (3); Described backing material plate (1) is calcium silicate board, and backing material plate posts decoration panel by viscose glue, and viscose glue solidify to form adhesive-layer (2).But inorganic material easily absorbs water, and the chlorion containing in the metal ion such as containing in calcium silicate board and glass magnesium plate etc. easily makes wooden skin variable color, distortion, therefore, hindered the application of the compound product of inorganic material and wooden skin on market.

Summary of the invention

The object of the present invention is to provide a kind of fire retardant performance good, can reach the composite decorating board that does not fire level, and good stability.

For achieving the above object, the present invention by the following technical solutions: a kind of composite decorating board, adopt sandwich construction, surface layer is wooden cortex, intermediate layer is metallic film, bottom is inorganic material layer, is adhesive layer or glued membrane ply of paper between layers.

Preferred as one, described inorganic material layer is calcium silicate board or glass magnesium plate.

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

Preferred as one, between described surface layer and intermediate layer, be nonwoven or tissue paper, be adhesive layer or glued membrane ply of paper between layers.

Preferred as one, for improving the texture of composite decorating board, inorganic material layer bottom can be set up a decorative layer, and decorative layer is wooden skin or paper.

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, the gross thickness of described nonwoven layer and wooden cortex or tissue paper and wooden cortex is 0.05mm-1mm.

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

Preferred as one, described metallic film is aluminium foil or tinfoil paper, thickness 0.01mm-0.1mm.

The invention has the beneficial effects as follows: in decorative panel of the present invention, by being provided with inorganic material layer, can making product reach and not fire level, the ratio of fire proofing material can reach 90%, has good fire retardant performance, and application scenario can further be expanded.

In addition, surface layer wood cortex, by the skin of paint on face and the metal film layer of below, isolates itself and bottom inorganic material and outside air, therefore in metastable state.

The effect of nonwoven of the present invention or tissue paper is to avoid wooden skin damage in process of production or tear.

Brief description of the drawings

Fig. 1 is the structural representation of embodiment of the present invention composite decorating board.

1-wood cortex, 2-nonwoven layer or paper, 3-adhesive layer, 4-metallic film, 5-calcium silicate board in figure.

Detailed description of the invention

Below in conjunction with accompanying drawing, the embodiment of the present invention is described further.

As shown in Figure 1, the embodiment of the present invention is decorated wooden skin, adopts sandwich construction, and surface layer is wooden cortex 1, and intermediate layer is metallic film 4, and bottom is calcium silicate board 5, is nonwoven or paper 2 between surface layer and intermediate layer, is polyurethane adhesive layer 3 between layers.

Wherein, the upper surface of surface layer wood cortex 1 can also be provided with skin of paint, on wooden cortex 1, 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 2, in the machine direction of nonwoven and wooden cortex 1, the machine direction of wooden skin is perpendicular.

1 layer of described wooden skin is natural veneer or recombinant decorative wood skin.

Described nonwoven layer 2 and wooden cortex 1 gross thickness are 0.05mm-1mm.

Described metallic film 4 is aluminium foil or tinfoil paper, thickness 0.01mm-0.1mm.

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 ensures, 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.
