Abstract

The present invention relates to a decorative veneer, which is characterized by that it is formed from solid batten as core layer, medium/high density fibreboard or solid multi-layer plywood as sandwich layer and two layers of facial layers, i.e. melamine facing paper or Baoli wood-grain ppaer and melamine gloss-finishing face layer or polyester face layer. Said invented decorative veneer is convenient for construction, can be arbitrarily cut into various required sizes and formed into various wood products. It has no need of painting and blocking hole with putty, and its cost is low.

Description

A kind of lamellar facing board

The invention belongs to laminar product with the characteristics that are connected between the thin layer of different materials, or rather, be a kind of with the solid wood bar be sandwich with comprise in/high density fiberboard, melamine graining paper, solid wood multi-layer glued board, the interconnective decorative board of solid wood wood finish thin skin individual layer and processing method thereof.

The combined plate kind that is used for building decoration in the market is a lot, but the processing and fabricating method is very complicated, cuts out the clear limit of plate → core-board through joiner bladed saw plate clear limit → facing three-ply board usually and connects combination → facing three-ply board and the compound preceding brush coating of core-board → facing three-ply board and be connected the surperficial filling fourth of compound → facing three-ply board eye putty multipass → wood strip edge sealing → brushing eight times with core-board vapour fourth to paint; Produce jointly both at home and abroad ^*Fixedly appearance pattern ^*The shaping combined material, be a kind of can not be reconfigured, can not arbitrary combination, only limit the use of in dado, wallboard, ceiling board, flanging button line, and cost is high.

The objective of the invention is to overcome the prior art shortcoming, propose a kind of various designing requirements that are fit to, arbitrarily saw is cut out the decorative board of combination.

Main technical schemes of the present invention: with the solid wood bar be laminboard layer, in/high density fiberboard or solid wood multi-layer sandwich panel are interlayer, the two-layer finish coat that superposes successively from inside to outside again is light surface layer or a polyester surface layer on melamine graining paper or Pola woodgrained paper polyester finishing paper and the melamine, constitutes lamellar facing board.

The characteristics of lamellar facing board of the present invention are to be the decorative board that sandwich is formed following structure with the solid wood bar:

First kind of structure: comprise solid wood bar sandwich, glossy paper on solid wood bar sandwich upper and lower surface symmetry superposes middle and higher density fiberboard interlayer, melamine graining paper, melamine successively constitutes seven layers of composite veneer material.

Second kind of structure: comprise solid wood bar sandwich, at solid wood bar sandwich upper and lower surface symmetry superpose successively solid wood multi-layer glued board interlayer, wood grain facing thin skin individual layer or Pola wood grain polyester finishing paper, unsaturated polyester (UP) surface layer, constitute seven layers of composite veneer material, described unsaturated polyester (UP) surface layer is the polyester surface layer of pitted skin, inferior light or light.

All there is the two layers of surface finish coat above-mentioned two kinds of structure top and bottom, also can cancel the two layers of surface finish coat at the sheet material back side, thereby constitute five layers of composite veneer material.

The concrete preparation method of composite veneer material of the present invention:

The preparation method of the composite veneer material of first kind of structure may further comprise the steps:

1. the outer surface of high density that is 2.5-5mm with two thickness or the medium density fibre board (MDF) two-layer finish coat that superposes successively from the inside to the outside respectively is a light surface layer on the thick melamine of thick melamine graining paper of 0.1-0.2mm and 0.15-0.5mm, and is the 300-1000 Tons per Inch at temperature 120-180 ℃, pressure respectively ²Following hot pressing obtains two superimposed layers;

2. the solid wood bar laminboard layer upper and lower surface that 8-26 is thick is coated the thick urea-formaldehyde resin adhesive of 0.5-1mm equably;

3. two superimposed layers and the finish coat that scribbles that the solid wood bar sandwich laminating step (1) of urea-formaldehyde resin adhesive obtains in step (2) upper and lower surface is outside, at the 5-30 Tons per Inch ²Pressure promptly obtains seven layers of composite veneer material down in fact.

The concrete preparation method of the composite veneer material of second kind of structure may further comprise the steps:

1. the solid wood bar laminboard layer upper and lower surface that 8-26mm is thick is coated the thick urea-formaldehyde resin adhesive of 0.5-1mm equably;

2. the solid wood bar sandwich laminating thickness that scribbles urea-formaldehyde resin adhesive in upper and lower surface is the solid wood multi-layer glued board interlayer of 2-3mm;

3. the symmetrical from the inside to the outside two layers of surface finish coat that superposes successively of solid wood multi-layer glued board interlayer upper and lower surface in step (2) is thick wood grain facing thin skin individual layer of 0.15-0.5mm or 0.05-0.2mm thick Pola graining paper and the thick polyester surface layer of 0.15-0.5mm, make hot pressing condition by hot pressing or conventional method with the cold subsides of glue: 60-80 ℃, 300-500kg/cm ²

Solid wood bar sandwich of the present invention, high density or medium density fibre board (MDF), solid wood multi-layer glued board, melamine graining paper, Pola graining paper, wood grain facing thin skin, melamine and pitted skin, inferior light or light unsaturated polyester (UP) surface layer all are commercially available prod.

Composite veneer material of the present invention can be made into the sheet material of different size, normally: long * wide * thick=2440 * 396-600 * 8-32 millimeter or 2440 * 1220 * 8-32 millimeter can be widely used in all kinds of woodworks that building decoration comprises door, door pocket, exterior window trim heating installation bag decorations, kitchen cabinet, furniture, dado.

Only need pass through the clear limit of blanking → connection combination → wood strip edge sealing operation when composite veneer material of the present invention is used for building decoration gets final product.

Advantage of the present invention:

The shaping combined material of the fixedly moulding pattern that composite veneer material of the present invention is better than producing in the market, can design blanking as required, be combined into various woodworks, and easy construction does not need brush paint and blocks up eye with putty, save man-hour, save raw material, free from environmental pollution, the cost of sheet material is low in addition, is fit to the needs of all kinds of consumption layers.
