The second object of the present invention is to provide a method for processing an overlay plate material that provides various functionalities by adding a reinforcing material to an adhesive used for the plate material and including a functional layer providing thermal discoloration, antibacterial and moisture resistance in the overlay plate material. have.

Hereinafter, with reference to the accompanying drawings will be described in more detail the processing method of the above-described overlay plate-like material.

First, referring to FIG. 1, a perspective view of an overlay plate-like material 1000 completed according to an embodiment of the present invention is illustrated.

In general, the plate material uses a plate material formed by thermally pressing wood fibers into a plate shape.

In the present invention, in using the wood fiber, despite having excellent durability, it is preferable to utilize domestic remnant wood resources, which have been mostly disposed of, because the diameter and length are difficult to use.

For example, the above-described remnant wood resources include pine, pine, pine, pine, yeast, juniper, pine, fir, birch, cypress, and the like. It can be processed into wood fibers using, and thermally compressed to form a plate-like material can be used.

That is, the one or more plate members formed by thermocompression bonding include the first plate member 1001 serving as the center member, the second plate member 1002 laminated on the first plate member 1001 described above, and the second plate member described above ( It is composed of a third plate-like material 1003 stacked on the 1002 to function as a finishing material may be prepared as an overlay plate-like material (1000).

At this time, Preferably, the above-mentioned first plate member 1001 and the third plate member 1003 use HDF (High Density Fiberboard) in which wood fibers are processed at a high density, and the first plate member 1001 described above. The second plate-like material 1002 bonded between the second plate-like material and the second plate material 1002 in a sandwich structure is preferably MDF (Medium Density Fiberboard), which is a wood fiber processed at a medium density.

That is, in the present invention, by using the MDF that is traded at a low price as the second plate member 1002, the process cost can be significantly reduced, and the first plate member 1001 serving as the core material and the first material serving as the finishing material The third plate member 1003 may be made of HDF, thereby firmly reinforcing the weak durability of the second plate member 1002, thereby forming an overlay plate member 1000 having significantly improved strength and durability as a whole.

Although one embodiment of the present invention has been described above, the spirit of the present invention is not limited to the embodiments set forth herein, and those skilled in the art who understand the spirit of the present invention may add components within the scope of the same idea. Other embodiments may be easily proposed by changing, deleting, adding, and the like, but this will also fall within the spirit of the present invention.

On the other hand, it will be referred to Figure 2 for a more detailed description of the processing method of the above-described overlay plate-like material.

In FIG. 2, a flowchart of a method of processing an overlay plate member according to an embodiment of the present invention is illustrated, and unnecessary description overlapping with the description of FIG. 1 will be omitted in the following description.

First, wood fibers are processed to prepare a first plate material serving as a center material, a second plate material stacked on the first plate material described above, and a third plate material serving as a finishing material, and at least one of an upper surface and a lower surface of the first plate material. Applying an adhesive mixed with a reinforcing material composed of industrial waste on one surface, laminating the second plate material on the first plate material one or more layers, and re-coating the above-described adhesive on the exposed surface of the second plate material to the third The overlay plate-like material forming step S10 of forming the overlay plate-like material by laminating the plate-like material may be performed.

At this time, the above-mentioned first plate material, second plate material and the third plate material is one selected from pine, pine, pine, pine, yeast, juniper, pine, pine, fir, birch, cypress It can be understood that the above remnants are processed into one or more platelets.

That is, in the present invention, it is easy to utilize domestic remnant wood resources that have been disposed of because they are shorter in length and have a shorter width and length than those of narcissus, which grow in tropical rainforests such as Malaysia. There is an effect of being able to produce an improved plate material.

In addition, as a preferred embodiment of the present invention, the first plate material and the third plate material used as the finishing material in step S10 is a plate-like material is processed with a higher density of wood fibers than the second plate material It is preferable to use those prepared by.

That is, as an example, the first plate and the third plate may be HDF, etc., in which the density of the wood fibers is high, and the second plate may be processed into a medium density fiber having a relatively low transaction price due to the low density of the wood fibers. The MDF is used to reduce the manufacturing cost.

On the other hand, the plate-like material composed of the above-mentioned medium-density fibers is inevitably reduced in durability because the density of the wood fibers are not tightly coupled, in order to solve this problem, the present invention uses a plate-shaped material formed of medium density Compared to the plate-like material, the thickness of the first plate-like material and the third plate-like material formed by processing at a higher density are processed relatively thick, so that when the first to third plate materials are laminated to form an overlay plate material structure, the rigidity is not deteriorated. It is preferred to be configured to not.

It can be understood that industrial waste reinforcements are mixed.

More specifically, the above-described artificial marble waste contains aluminum hydroxide as a main component, and the above-described aluminum hydroxide generates steam by pyrolysis during combustion, thereby lowering the concentration of the combustion gas and lowering the temperature around the combustion point to suppress combustion. In addition to performing the function, when the artificial marble is processed into a powder, a small amount of phosphorus contained in the powder may react with aluminum hydroxide to increase the effect of the flame retardant.

In addition, the above-mentioned glass fiber waste may be used, for example, mineral wool and glass wool waste. Such glass fiber, as is well known, has excellent thermal insulation by tightly securing a fine air layer therein to block the movement path of heat. In addition, it is made of inorganic glass, which is close to non-combustible, and has a property of melting slowly without burning even if a fire occurs, thereby delaying the spread of fire and securing an evacuation time.

In order to further maximize the reinforcing effect, the first plate member 1001 and the third plate member 1003 may be formed to be thicker than the second plate member 1002.

Further, in the present invention, in joining the first plate-like member 1001, the second plate-like member 1002, and the third plate-like member 1003 described above, the artificial marble waste which is an industrial waste to an adhesive, rather than a general adhesive as an adhesive, is used. And at least one industrial waste reinforcement material selected from glass fiber wastes is mixed to supplement the strength of the artificial marble and glass fiber, thereby providing an overlay plywood having improved durability by providing high resistance to flame retardancy, warpage, and torsion.
