Description

fireproof board

technical field

The utility model provides a board, in particular to a fireproof board.

Background technique

Panels are widely used in people's daily life, especially in compartments or wall installations, and even door panels, etc., are often used in panels.

For the sake of nature, the traditional plank is made of solid wood, so that the beauty of its natural texture can improve the visual appeal. However, it cannot be denied that due to the preciousness of natural resources and the sustainable development of the ecology, it is impossible to obtain solid planks by cutting down trees and hindering the ecological balance. Therefore, the existing natural veneer with textures, Lay other material substrates to form boards with wood texture as the surface material.

Whether it is a solid board or a laminated veneer board, it cannot be denied that fire prevention is a major focus, especially due to the concentration of urbanized population. If there is a fire, non-fireproof materials will have a combustion-supporting effect, causing heavy casualties and property damage. Loss, I believe that the tragedy caused by fires in recent years is shocking and still fresh in memory.

In view of this, in all major advanced countries, there are certain standards or norms for this building or indoor ditch board, that is, it must have a certain degree of fireproof or non-combustible effect before it can be used as a building material. The safety of life and property should be treated positively.

At present, there are magnesium oxide base plates on the market, the surface of which is made of veneer. Since magnesium oxide is an inorganic component, it is non-flammable and has no combustion-supporting effect. Basically, the laminated thin-layer veneer has limited combustion support. , so it can meet the basic requirements of fireproof panels.

The only disadvantage of this kind of board is that the acid or alkali of magnesium oxide will penetrate into the veneer after a period of time, and since the veneer is a thin piece of natural wood, this penetration will turn the veneer black, resulting in aesthetic defects. In addition, due to climate change, the discoloration of the veneer will be aggravated, which is unsuitable and unsightly for occasions that must be used for a long time.

Contents of the invention

In view of this, the purpose of the present utility model is to provide a fireproof board, which has the effect of fireproofing.

The utility model is a fire-proof board, which is characterized in that it comprises: a bottom plate selected from magnesium oxide or calcium silicate; Bottom plate; one side of leather, which is made of natural thin wood chips and attached to the middle compartment.

The middle layer is spherical paper.

The interlayer is a non-woven fabric impregnated with melamine resin.

Description of drawings

For further revealing the concrete technical content of the present utility model, please refer to accompanying drawing at first, wherein:

Fig. 1 is an exploded view of the plate structure layer of the present utility model;

Fig. 2 is the finished product schematic diagram of sheet material bonding of the present utility model;

Fig. 3 is a sheet forming flow chart of the present invention.

Detailed ways

As shown in the figure, basically, the panel of the present invention is formed by laminating a base plate 1, a side skin 2 and a middle compartment 3.

Among them, the bottom layer 1 is a fireproof board, preferably a magnesium oxide board or a calcium silicate board. It depends on the needs, but basically it is advisable to standardize, but this is an existing technology, so it is not intended to go into details.

The skin 2 is a natural veneer, which can be planed into thin slices through natural wood to make it have a natural wood grain, and its length and width dimensions correspond to the aforementioned bottom plate 1, so it can be laminated accordingly, which is also an existing one. Zhiyi, so I will not repeat it.

And the present utility model is easy to existing technology, is to be between bottom plate 1 and dough 2, add a middle interlayer 3, this middle interlayer 3 is to be the synthetic paper that takes PP as main raw material, and it has the effect of natural paper. It has the advantages of light specific gravity, waterproof, weather resistance, acid and alkali resistance, and two-way tear resistance. In addition, it has no dioxin black smoke and is an environmentally friendly material. "PEPA" (English name PEPA) is an example. Information about the physical properties and characteristics of this pearlescent paper can be obtained from the website: http://www.pepa.com.tw, and it has a back-adhesive finished product for sticking In addition, the middle partition layer 3 can also be obtained by impregnating PP non-woven fabric with melamine resin.

Please refer to Fig. 2 again, the fire-proof board of the present utility model is that the interlayer 3 is sandwiched between the dough 2 and the bottom plate 1, and forms a board with a three-layer structure, because the interlayer 3 is for preventing Acid-base, and non-stretchable, therefore, after bonding, the acid-base of the substrate 1 can be prevented from penetrating into the dough 2, so the dough 2 will not change color.

Please refer to Fig. 3 again, when the plate of the utility model is produced, it is based on the base material 1 of the magnesium oxide plate, after the middle compartment layer 3 is attached, the surface 2 of the natural veneer is glued and then pressed, so that It sticks closely and forms an inseparable board. Finally, UV glue has to be applied for the protection of the skin 2.

Therefore, through the implementation of the present utility model, its obtainable effect has the following numbers:

(1) Eliminate the acid and alkali penetration of the skin, which can effectively prevent the skin and wood grain from turning black, and it has the effect of covering the bottom, which can highlight the texture of the wood grain.

(2) Effective fire prevention and non-combustibility, because the base plate used in the utility model is a magnesium oxide board or a calcium silicate board, which all have non-combustible characteristics, so it can be widely used in compartments, interior decoration and door panels, and even Where other plates are suitable.

What is disclosed in the utility model is a kind of preferred embodiment, and all partial changes or modifications derived from the technical idea of the utility model and easily deduced by those who are familiar with the art will not deviate from the utility model. scope of patent rights.

Claims (3)

1. A fireproof board, characterized in that, comprising: a base plate selected from magnesium oxide or calcium silicate; A middle compartment layer produced by imitating paper made of PP material, and attached to the bottom plate; One side of the skin is made of natural thin wood chips, which are attached to the middle compartment. 2. The fireproof board according to claim 1, wherein the middle layer is spherical glossy paper. 3. The fireproof board according to claim 1, wherein the interlayer is made of non-woven fabric impregnated with melamine resin.
