Abstract

The utility model discloses a novel density board which comprises a panel, a core board and a back board which are compounded, wherein the panel, the core board and the back board are density boards, and glass fiber cloth layers are arranged between the panel and the core board and between the core board and the back board. Preferably, the panel and the back board are medium-density boards, and the core board is a low-density board. The ratio of panel thickness to core board thickness to back board thickness to glass fiber cloth layer thickness is 4:3:4:1. The novel density board has the advantages that the two arranged glass fiber cloth layers can well play a role in resisting high temperature, heat transferred from the panel is reduced or delayed to be transmitted to the core board through the arranged glass fiber cloth layer when high temperature combustion occurs, and is reduced or delayed to be transmitted towards the back board again through one glass fiber cloth layer, thus the damage degree to the novel density board can be minimized, and the safety is ensured.

Description

A kind of novel density plate

Technical field

The utility model relates to a kind of wood-based plate, especially novel density plate.

Background technology

The density board of generally using in house decoration, is that to take wood fibre or other plant fiber be raw material, applies the artificial board that Lauxite or other applicable adhesive are made.Existing density board, through the one-time formed sheet material of HTHP after solid wood is pulverized, by the difference of density, can be divided into high-density plate, medium-density plate, low-density plank (medium-density plate density is 550 kilograms-880 kilograms/cubic metre, high-density plate density >=880 kilogram/cubic metre more than).Its advantage is: 1. lower than natural timber price.2. veneer breadth is large, also can do to increase and decrease according to customer requirement.3. steady quality can be controlled when producing comprehensively, and part mass property is better than natural timber (against pressure, be out of shape the characteristics such as little).4. product surface has reached direct instructions for use, greatly reduces processing cost.5. sheet material internal structure is fine and close, in length and breadth to uniform quality, can process arbitrarily, and it,, with its good characteristic, is used widely when house decoration.But density board after all be take wood fibre as primary raw material, woodwork plate, the decorative panel of it and other are the same, exist the shortcoming of not resistance to high temperature, meet high temperature and are easily out of shape.

Therefore, be necessary existing density board to improve.

Summary of the invention

The purpose of this utility model is the novel density plate designing in order to solve the deficiency of above-mentioned technology, and this novel density plate has resistant to elevated temperatures characteristic.

The novel density plate that the utility model is designed, is composited by panel, central layer and backboard, and described panel, central layer and backboard are all density board, is all being provided with glass fibre layer of cloth between described panel and central layer and between central layer and backboard.

As preferably:

Described panel and backboard are medium-density plate, and described central layer is low-density plank.

Described plate thickness: central layer thickness: back plate thickness: the ratio of glass fibre ply gage is 4:3:4:1, through test, such scheme practicality is the strongest.

The novel density plate that the utility model is designed, its beneficial effect is between described panel and central layer, and between central layer and backboard, be all provided with glass fibre layer of cloth, the double-deck glass fibre layer of cloth arranging, can better play resistant to elevated temperatures effect, when being subject to the situation of high-temp combustion, the heat being got off by panel transmission is by the glass fibre layer of cloth being provided with, heat is weakened or is slowed down to central layer transmission, again by layer of glass layer of cloth, heat weakens or slows down toward back plate transmission again, can make like this damaged condition of density board reach and minimize, also guaranteed safety.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of embodiment 1;

In figure: panel 1, central layer 2, backboard 3, glass fibre layer of cloth 4.

The specific embodiment

Below by embodiment, the utility model will be further described by reference to the accompanying drawings.

Embodiment 1:

As shown in Figure 1, the described novel density plate of the present embodiment, by panel 1, central layer 2 and backboard 3, be composited, described panel 1, central layer 2 and backboard 3 are all density board, between described panel 1 and central layer 2 and between central layer 2 and backboard 3, be all provided with glass fibre layer of cloth 4, described panel 1 and backboard 3 are medium-density plate, and described central layer 2 is low-density plank.

The described novel density plate of the present embodiment, its beneficial effect is between described panel 1 and central layer 2, and be all provided with glass fibre layer of cloth 4 between central layer 2 and backboard 3, the double-deck glass fibre layer of cloth 4 arranging, can better play resistant to elevated temperatures effect, when being subject to the situation of high-temp combustion, the heat being transmitted by panel 1 is by the glass fibre layer of cloth 4 being provided with, heat is weakened or slows down to central layer 2 to be transmitted, again by layer of glass layer of cloth 4, heat again weakens or slows down toward back plate 3 and transmits, can make like this damaged condition of density board reach and minimize, also guaranteed safety.

It should be noted that: the thickness of described panel 1, central layer 2, backboard 3, glass fibre layer of cloth 4 can be appointed and get in the knowledge of those skilled in the range, preferred plan is described panel 1 thickness: central layer 2 thickness: backboard 3 thickness: the ratio of glass fibre layer of cloth 4 thickness is 4:3:4:1.

Specific embodiment described herein is only to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
