The composite board comprises a core body and is characterized in that the upper surface and the lower surface of the core body are connected with a plurality of surface layers, and the surfaces of the surface layers are provided with cuticular layers. The composite board has the advantages of low manufacturing cost, attractive appearance and the like.

Description

A kind of multi-layer sheet

Technical field

The utility model belongs to the timber field, relates to a kind of plate, especially relates to a kind of multi-layer sheet.

Background technology

Timber is widely used in building decoration and furniture, family adorn, closely bound up with our daily life, and society becomes to increasing for the plank material day by day now, simultaneously, people also too pursue material life now, just cause the noble quality sense of plank material in the agproximation plate once to add, make a large amount of felling of log in the forest, cause now natural resources deficient day by day, more make the costing an arm and a leg of plank material, because of falling sharply of international deforestation amount makes the source of goods in great shortage.Obviously so high-quality timber of employing adapts to the demand in market, is unfavorable for the development that society is permanent.Just produced the three-ply board that can adapt to social demand, three-ply board sticks together three layers of veneer and makes by the different texture direction thereupon.

Though the effect when three-ply board not only can realize that high-quality timber uses, and price is cheaper makes it just to popularize rapidly in modern society and come, and wooden three-ply board commonly used is inflammable, for fire hides some dangers for.The three-ply board outward appearance is single in addition, dullness, and decoration has obviously increased the expense of installation and the cost of manufacturing in addition; The outer surface plate of three-ply board is directly binded by the resin viscose and forms, because plank material itself all has good water imbibition, and neither in the combining structure have a good waterproof effect, when if wooden plywood is used in the heavier environment of moisture, this wood plywood is mouldy easily, growth cyanines tongue, or influence wooden plywood the bonding effect.

Summary of the invention

The purpose of this utility model is at the problems referred to above, and the multi-layer sheet that a kind of number of plies is more, intensity is higher, cheap is provided.

For achieving the above object, the utility model has adopted following technical proposal: this multi-layer sheet, comprise core body, and it is characterized in that described core body upper and lower surface is connected with the several layers top layer, epidermis is all posted on the surface in the described top layer.

In above-mentioned a kind of multi-layer sheet, described epidermis is collection layer skin.

In above-mentioned a kind of multi-layer sheet, described top layer has six layers.

In above-mentioned a kind of multi-layer sheet, scribble melamine on the described collection layer skin.

Compared with prior art, this multiple-plate advantage is: the number of plies that comprises in the top layer is more, has strengthened working strength of the present utility model.

Epidermis has strengthened the attractive in appearance of surface of the present utility model for collection layer skin, avoids profile too single.

Description of drawings

Fig. 1 is that structure of the present utility model bursts schematic diagram

Among the figure, 1, core body; 2, top layer; 3, epidermis.

The specific embodiment

As shown in Figure 1, this multi-layer sheet comprises core body 1, and described core body 1 upper and lower surface is connected with several layers top layer 2, and described top layer 2 has six layers, and the number of plies that comprises in the top layer 2 has six layers, has strengthened working strength of the present utility model.Epidermis 3 is all posted on the surface in the described top layer 2.Epidermis 3 has strengthened the attractive in appearance of surface of the present utility model for collection layer skin, avoids profile too single.

Can draw corresponding pattern according to required on the above-mentioned collection layer skin, avoid the too single situation of plate body outward appearance.

Six above-mentioned laminate bodies are connected on the upper and lower surface of core body 1 again, and are symmetrical arranged by glued together.

Described epidermis 3 is collection layer skin; Scribble melamine on the described collection layer skin.The melamine that scribbles on the collection layer skin can avoid flaggy directly to contact with malaria, protects the permanent drying of flaggy, postpones the life-span of its use.In addition, the melamine on surface has the fireproof effect simultaneously, and its fusing point is higher, and is difficult for lighting, and it is inflammable again to stop wooden three-ply board, for fire hides some dangers for.

Claims (4)

1. a multi-layer sheet comprises core body (1), it is characterized in that, described core body (1) upper and lower surface is connected with several layers top layer (2), and epidermis (3) is all posted on the surface in described top layer (2).

2. a kind of multi-layer sheet according to claim 1 is characterized in that, described epidermis (3) is collection layer skin.

3. a kind of multi-layer sheet according to claim 1 is characterized in that, described top layer (2) have six layers.

4. a kind of multi-layer sheet according to claim 2 is characterized in that, scribbles melamine on the described collection layer skin.
