Description

FIELD OF THE INVENTION The present invention relates to a flame retardant panel and a method of manufacturing the flame retardant panel.

The present invention relates to a flame retardant panel, and more particularly, to a flame retardant panel in which the surface of a panel used for an interior of a room is provided with a function of flame retardancy so that the pattern of the original wood itself is expressed as it is.

Generally, it is possible to produce an atmosphere suitable for the user's taste by using a panel having various pattern shapes for the interior of the room.

Conventional panels (MDF, PB, and other materials) as described above are mostly organic materials composed of carbon, hydrogen, and oxygen, and have a property of easily burning.

These panels are not equipped with flame-proofing function. When a fire occurs, flame easily ignites and it spreads all over the room in a short time, causing damage to property and serious damage to human life.

In order to solve the above-mentioned problems, there has been recently proposed a flame retardant panel in which a flame retardant agent is added when fabricating a panel. However, the flame retardant panel is mixed with the flame retardant material inside the panel during molding, The flame is not ignited on the panel itself due to the flame retardant, so that the risk from the fire can be prevented.

However, the conventional flame retardant panel as described above can not easily ignite the flame and can eliminate the risk from the fire. However, since the surface can not express the state of the wood, the design pursued by modern people can not be expressed.

Therefore, in recent years, a flame retardant panel containing a flame retardant has been disclosed, that is, Patent No. 10-1354526. However, in the conventional flame retardant panel, a melamine sheet is adhered to one side of the material, and a flame retardant UV primer, The middle and top coats were coached sequentially, and the flame retardant panel coated with the surface protection film was introduced.

However, in the flame retardant panel as described above, a surface protective film having a uniform pattern is produced by a device and adhered to the surface. When such a flame retardant panel is installed in a room, There is a disadvantage that the user can not receive the feeling of the wood itself pursued.

Therefore, according to the present invention, a flame retardant panel is manufactured so that flame is not ignited on a panel itself when a fire occurs, thereby preventing property damage caused by a fire and valuable personal injury. Also, when a panel is constructed, The present invention is directed to providing a flame retardant panel capable of satisfying consumers' desires by allowing them to survive.

This invention

The present invention relates to a flame-retardant flame-retardant material having flame retardant function, which laminate a flake using the pattern obtained from a log as it is, and adjust the sensitivity of the flake shape represented by the flake to a surface roughness And the coloring layer and the coating layer are sequentially applied to the surface of the substrate in a state in which it is arbitrarily adjusted, and the flame is not ignited when a fire occurs, so that property and personal injury caused by fire can be prevented in advance, So that it can be used in a state in which it can be tailored to the user's taste and overall interior since it can be used as a natural pattern rather than an artificial pattern.

1 is a sectional view showing a structure of a flame retardant panel according to the present invention;
2 is a view showing a process of manufacturing a flame retardant panel according to the present invention.

Hereinafter, the configuration of an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows the structure of a flame retardant panel 100 according to the present invention. In the flame retardant panel 100, a laminate 400 is placed on one surface (upper surface) of a flame retardant material (MDF) 200, To be adhered by the adhesive 300 applied therebetween.

At this time, the adhesive 300 uses a wood bond (an eco-friendly wood bond) used for bonding wood.

The adhesive 300 is applied to the top surface of the flame retardant material 200. The application method may be directly applied by a worker using a roller or a brush with an adhesive, The lower and upper rollers are installed in the lower part of the roller so that the lower part of the roller is maintained in a state of being settled in the adhesive so that the flame retardant material 200 passes between the pair of rollers. So that the adhesive 300 is uniformly applied to the lower surface of the flame retardant material 200 while the roller being positioned rotates.

The colored layer 500 is applied to the upper surface of the vignetting 400. In this case, the colored layer is made of a wood coloring agent, and the color is a color required by the customer.

The veneer 400 may be classified according to the type of the production area and the veneer of the wood.

For example, wood produced in the United States is: ① Black Cherry, Walnut, Maple (SOFT & HARD) ② Hard Maple: Bird Eye, BIRD-EYE, Pygmy Maple (CURLY), Water Drop Maple ③ Oak: Red Oak, White Oak ④ Ash (ASH): black ash, brown ash, white ash, and rosewood, mahogany, and squirrel in the case of Hongsung, Mitsun, and South American mountains in North America.

Since the coloring layer 500 uses the log itself as it is, the surface of the coloring layer 500 is not smooth and rugged. Thus, when the coloring layer 500 is coated on the surface of the veneer 400, The coloring layer 500 penetrating the rugged portion on the surface of the vignetting 400 is applied in a state in which the surface is uniform so that the pattern of the vignetting itself can be expressed as it is when viewed from the outside.

The flame retardant panel 100 is completed because the flame retardant urethane coating 600 is applied to the upper surface of the colored layer 500.

FIG. 2 is a drawing (manufacturing process) of a flame retardant panel 100 according to the present invention,

A step S1 of preparing a flame retardant material 200 (MDF);

The flame retardant material 200 can be manufactured by itself or can be used by being put on the outside. It is a fiber board formed by thermo-compression molding a piece of wood under high temperature and high pressure with an adhesive (flame retardant bond) About 0.4 to 0.8.

(S2) applying an adhesive to the upper surface of the flame retardant material;

The application of the adhesive to the upper surface of the flame retardant material 200 is intended to firmly attach the flake 400 to the upper surface of the flame retardant material. It is possible for the operator to apply the adhesive agent by hand, , So that the adhesive can be applied through a mechanical device (this is described in details in the former, and a detailed description will be omitted)

(S3) allowing the laminated wood (400) to be adhered to the top surface of the flame retardant panel (200) to which the adhesive is applied, by adhesive force of the adhesive;

The veneer 400 is used to process logs to a thickness that can be used in a flame retardant panel. The thickness of the flake panel used in the flame retardant panel is most preferably used within the range of 02 to 06 mm.

(S4) making the veneer (400), which is laid on the top surface of the flame retardant panel (200) and firstly adhered by an adhesive, be pressed by tightly adhering the veneer using a hot press.

Since the laminated wood 400 mounted on the flame retardant panel 200 is adhered by the adhesive force of the adhesive 300 and is not tightly adhered to the flame retardant panel 200, So that the flame-retardant panel and the whole veneer can be glued together in a relaxed state.

This is done by pressing the veneer 400 at a temperature of 100 to 120 ° C for about 40 to 60 seconds.

(S5) of working the surface of the veneer 400 which is tightly adhered by the hot presser with sandpaper according to the application;

In the above step, the surface of the vignetting 400 is polished with sandpaper. The vignetting 400 is a method of cutting the wood to a thickness suitable for the flame-retarding panel, The texture of the veneer surface layer is adjusted according to the interior of the room or the taste of the user using the panel 100. The surface of the veneer 400 can be trimmed by using sandpaper.

In other words, if the surface of the veneer is desired to express rough texture, it can be used as it is without performing the sandpaper operation. If the veneer surface is too rough, it is possible to use sandpaper to tailor it to the texture of the surface will be.

(S6) spraying the flameproof lacquer onto the surface of the veneer 400 that has undergone the hot pressing step or sandpapering operation;

In the above step, when the veneer 400 is squeezed using a hot press, the adhesive is exposed to the surface through the veneer, so that the coloring layer is not coated by the adhesive that has passed through the veneer, To prevent coloring of the laminated wood 400. The flame-retardant urethane lacquer is sprayed onto the surface of the laminated wood 400 to such an extent that the adhesive can cover the laminated wood 400, To be covered.

A step (S7) of applying a coloring agent to the surface of the vignette 400 that has undergone the above step, that is, the coating layer on which the flame retardant urethane lacquer is applied;

The coloring layer 500 is applied to the surface of the veneer which is kept smooth without any foreign substance due to the spraying of the flame-retardant urethane lacquer. This is because the coloring agent to be applied is time- The coloring agent is applied 2 to 4 times so that the coloring layer 500 can be applied.

A step (S8) of coating the colored layer (500) coated with the urethane coating (600) by the coating process;

 The flame-retardant urethane coating 600 has a flame-retardant function. The flame-retardant urethane coating 600 has a primary coating (priming) on the surface of the coloring layer 500 and then a secondary coating (topping) And the second stage is done by about one to three operations.

At this time, the coating interval is at least about 10 to 20 minutes, and the drying temperature of the coating layer is at least 30 to 40 DEG C, and the drying time is about 6 hours / RTI >

The flame-proofing test results of the flame-retardant panel 100 thus completed are shown in Table 1 below.

Test standard: Flame retardant performance standard (National Security Notice No. 2015-1) Article 7 Test Items standard
