Description

Wooden board for board mat {board for wood carpet}

The present invention relates to a wooden piece for a mat mat, and more particularly, to prevent the wooden piece in the manufactured state from bending to one side even if the veneer is adhered to only one side of the wooden piece body during manufacture.

Generally, the mat is about 3-4 mm thick, about 30 cm long, and about 2.5 cm wide, on a sheet of synthetic resin sheet 1 having a rectangular shape as shown in FIGS. A plurality of wood pieces (2) are bonded in a mosaic arrangement to form a wide rectangular panel, the four sides of the rectangular panel is wrapped and protected by a fiber finishing material (3) having tough physical properties The edge finishing material is sewn on a piece of wood 2 forming a panel as a fiber material yarn 4 having tough physical properties.

The wood piece (2), which is a component of the above-mentioned wood mat, generally uses solid wood such as maple, oak, and chestnut as a material. The maple, oak, and chestnut are hard to maintain their beautiful wood texture. The quality of wood mat for wood mat is very good, but it is a species that cannot be easily purchased in Korea, so the price is high because it is imported from all foreign countries, and the price of wood mat is also expensive. have.

However, in recent years, thanks to the development of technology, low-priced solid wood, which can be easily purchased in Korea, is processed, and then the veneer is glued to the processed solid wood. The wooden mat is manufactured by making wood pieces that have the same visual impression but have strong surface strength. Therefore, the quality of the wooden mat is slightly lower than that of expensive wood, but the price is cheaper. Preference is on the rise.

Therefore, a technique of manufacturing a piece of wood for mat mat by processing a low-cost solid wood and glue the veneer thereon, which will be described in more detail as follows.

The prior art wood piece for mat mat is a rectangular wooden piece body 11, the water-soluble adhesive layer 12 containing water applied to one side of the wooden piece body, as shown in Figs. It is composed of a veneer 13 of a thin thickness adhered to the water-soluble adhesive layer.

In a wooden mat made of wood pieces having such a structure, it is understood that the veneer 13 adhered to one side of the wood piece body 11 is exposed to the outside.

Referring to the process of manufacturing a piece of wood according to a conventional embodiment of such a structure for reference, a water-soluble adhesive containing water on one side of the rectangular wood piece body 11 made by processing a low-cost solid wood After applying evenly, the veneer 13 made by turning the wood thinly on one side of the wood piece body 11 to which the water-soluble adhesive is applied is temporarily bonded so that the veneer does not fall off temporarily.

Then, when the wood piece main body 11 to which the veneer 13 is temporarily bonded is put into a heat press and pressed while applying heat for a predetermined time, the moisture component of the water-soluble adhesive between the wood piece main body 11 and the veneer 13 is As the water-soluble adhesive is hardened in this process as it escapes to the outside due to heat, the veneer 13 is firmly adhered to the veneer 13 while securing the water-soluble adhesive layer 12 on one side of the wood-body 11. As is known, it is almost the same method as the conventional technique of adhering veneer to furniture crimp plywood.

However, as in the conventional embodiment, when the wood piece to which the veneer 13 is bonded with only one surface of the wood piece body 11 with the water-soluble adhesive layer 12 interposed therebetween, when heat-compressed by heat press in the manufacturing process As the moisture component of the water-soluble adhesive escapes to the outside, a large part of the moisture component penetrates the wood piece body 11 or the veneer 13 and stays thereafter. 11) due to the difference in shrinkage between the veneer 13, there was a problem that the piece of wood bent in one direction as shown by the dashed-dotted line of FIG.

However, in the wooden boards used for furniture, as mentioned above, even if the wood veneer is stuck to the plywood plywood, the wooden boards are not severely bent to one side, because the thickness of the compressed plywood is usually very thick, 1 cm or more, In the piece of wood used for the mat, since the thickness is about 3 mm thin, when the wood veneer 13 is adhere | attached on one side of the wood piece main body 11 which comprises the said wood piece, the piece of wood will gradually become one side. It is bent, it is understood that the quality of the wooden mat is greatly degraded even if the wood piece becomes unusable or used for the wooden mat.

Accordingly, in order to solve the problems of the conventional embodiment described above, the seat for the seat has been filed (Application No. 1998-2000) and registered (Registration No. 187622). The explanation by 6 is as follows.

Conventionally, the wooden piece for the matting wood of the other embodiment has a rectangular wooden piece body 21, a first water-soluble adhesive layer 22 and a second water-soluble adhesive layer 22a applied to both sides of the wooden piece body, The first veneer 23 and the second veneer 23a each having a thin thickness adhered to each of the water-soluble adhesive layers 22 and 22a, respectively. Any one of the first veneer 23 and the second veneer 23a adhered to both sides of the wood piece body 21 is exposed to the outside.

In the process of manufacturing a piece of wood according to another embodiment of the conventional structure of this structure, evenly apply a water-soluble adhesive to both sides of the rectangular wooden piece main body 11 made by processing a low-cost wood and then the water-soluble adhesive is applied Each side of the wood piece main body 21 is temporarily bonded to each of the veneer 23 (23a) of the same shrinkage made by turning a separate solid wood thinly so that each veneer does not fall temporarily.

Then, the wood piece main body 21 to which the veneers 23 and 23a are temporarily bonded is put into a heat press and pressed while applying heat for a predetermined time, which is between the wood piece main body 21 and the veneers 23 and 23a. Since the water-soluble component of the water-soluble adhesive is released to the outside by heat, the water-soluble adhesive is hardened in this process, so that the water-soluble adhesive layers 12 and 12a are secured on both sides of the wood-body main body 21, respectively. 13a is firmly completed.

Therefore, after the veneers 23 and 23a are adhered to both sides of the wood piece body 21, the moisture contained in the wood piece body 21 and the veneers 23 and 23a may be dried while being drained to the outside. When the veneers (23) and (23a) have the same shrinkage rate, the warp does not occur in either direction, so when the wooden mat is made by using the wood piece of another conventional embodiment, the whole wood piece is seen from the outside. Compared to the wooden mat made using the material, there is no compromise in appearance and quality.

However, the wood mat for wood mat according to another embodiment of the prior art has to adhere the veneer having the same shrinkage rate to each side of the wood piece body during manufacture, so that the production process is complicated and the productivity is reduced due to the deterioration of workability. Of course there is a problem in that the manufacturing cost of the product increases due to the excessive use of unnecessary veneer when considering that only one side of the wood piece is exposed to the outside when making a wooden mat using the manufactured wood piece.

The present invention has been devised to solve the above-described problems, even if the glued wood only on one side of the main body of the wood piece constituting the wood piece, so that the wooden piece is not bent to one side after the production of the wood piece The purpose is to reduce the manufacturing cost as well as improve the workability due to the adhesion of city veneer.

101. Wood piece body 102. Moisture reactive adhesive layer

103. Veneer

According to the present invention for achieving the above object, a rectangular piece of wood piece main body, a water-reactive adhesive layer applied to one side of the wood piece body, melted by heat and hardened by moisture, and the water reactive adhesive There is provided a wooden mat for a mat made of thin veneer glued onto a layer.

Hereinafter, the present invention will be described in detail with reference to FIGS. 7 to 8.

7 is a perspective view showing a wood piece for the present invention mat mat, Figure 8 is a longitudinal sectional view showing a wood piece for the present invention mat mat, the wood piece for the present invention wood mat is a rectangular piece of wood piece 101 And a water-reactive adhesive layer 102 having a property of being applied to one side of the wood piece body and being melted by heat and hardened by moisture, and a veneer 103 having a thin thickness adhered to the water-reactive adhesive layer.

Referring to the manufacturing process of the wood piece for the present invention wood mat mat as described above by reference.

First of all, in order to manufacture the present invention wood matting wood piece, it is understood that the wood piece body 101 on the rectangular plate is provided by processing a low-cost wood as a prerequisite.

When a moisture-reactive adhesive having a property of being melted by heat and hardened by moisture is applied to one side of the provided wood-clad body 101, the moisture-reactive adhesive starts to harden while immediately absorbing moisture components contained in the air. At this time, the veneer 103 made by thinly turning the wood to one side of the wood piece body 101, the moisture-reactive adhesive is applied to the temporary glue so that the veneer does not fall off temporarily.

Then, when the wood piece main body 101, which is temporarily bonded to the veneer 103, is put in a heat press and pressed while applying heat for a predetermined time, the moisture-reactive adhesive between the wood piece main body 101 and the veneer 103 is heated by heat. As the film melts, the film becomes uniform. After stopping the operation of the heat press, since no more heat is transferred, the water-reactive adhesive attracts the surrounding moisture and starts to harden by moisture while absorbing moisture. 103 is primarily bonded to the piece of wood main body 101 while maintaining a certain adhesive strength.

Subsequently, when the veneer 103 is primarily bonded to the main piece of wood piece 101 and stored at room temperature for a certain period of time, the moisture-reactive adhesive between the wood piece body 101 and the veneer 103 is to absorb moisture around. As the moisture is absorbed more and more, it is completely hardened, so that the veneer 103 is firmly and completely adhered to the solid wood while the moisture-reactive adhesive layer 102 is secured to one side of the wood-clad body 101 so that the wood-fiber is manufactured. will be.

Therefore, in the state in which the veneer 103 is adhered to one side of the wood piece main body 101 or after adhesion, since the moisture component is always absorbed by the moisture-reactive adhesive layer 102, the wood piece main body 101 or the veneer 103 is As the moisture component does not penetrate, since the wooden piece body 101 and the veneer 103 are not contracted or contracted even during the drying process, the warp is hardly caused to one side.

Therefore, the present invention wood matting wood piece only need to adhere the veneer only on one side of the wood piece body during manufacture, so that the production process is simple and the productivity can be increased by improving the workability. As it decreases, the basic effect of lowering the manufacturing cost of the wooden mat is further reduced, and the quality of the mat made of the mat made by using the wood piece is not bent to one side, but the effect is very excellent.
