Description

Method for manufacturing of board for flooring materials

The present invention relates to a wood piece for flooring, and more specifically, to reduce the raw material costs by varying the manufacturing process so as not to be easily deformed by moisture.

Generally, wood pieces used for various flooring materials have an appropriate size for their use. As shown in FIGS. 1 and 2, wood pieces used for living room floors have a rectangular shape and the size is about 50-60 cm in length. It is about 8-10cm long and 5-6mm thick, and the wood pieces used for the mat are also rectangular in shape, about 30cm long, 3cm wide and 3mm thick.

When using the wood piece for the living room floor as shown in Figures 1 to 2 to form a large living room floor of a certain area by combining a mosaic type, as shown in Figures 3 to 4 when using the wood piece for a wooden mat. After arranging several pieces on the synthetic resin sheet 1 in a mosaic manner, the edges are sewn with the edge finishing material 2 to form a wooden mat.

Thus, one method is required in order to manufacture wood pieces used for various flooring materials such as living room floors and wooden mats, and the conventional method is the thickness of the flooring material of the product that will use cylindrical solid wood as shown in FIG. In the case of 6-7 mm, 3-4 mm in the case of wooden mats) to obtain a wooden board by cutting with a cutting saw, and cutting the wooden board again with a cutting saw so that the length and width of the flooring material of the product to be used Obtaining the wood piece body 11, and smoothing by sanding the upper surface of the wood piece body, and applying a UV coating agent to the upper surface of the wood piece body 11 that has been processed. Forming a UV coating layer 12 having a predetermined thickness, and applying a urethane paint to the upper surface of the UV coating layer to form a urethane coating layer 13 having a predetermined thickness It is performed in are made.

Therefore, a wide wooden board having the above thickness when cut by a cutting saw provided separately so that the cylindrical wood is the floor thickness of the product to be used (6-7 mm if the product to be used is a living room floor, 3-4 mm if a wooden mat). The wide wooden board thus obtained is cut by a cutting saw provided separately so as to be the length and width of the flooring material of the product to be used again, thereby obtaining the wooden piece body 11.

When the upper surface of the wood piece body 11 obtained as described above is sent to the top surface of the wood piece body as a sender to make it smooth, and then the UV coating agent is applied to the top surface of the wood piece body by roll coating and dried several times. , The upper surface of the wood piece body 11 is formed with a UV coating layer 12 to a predetermined thickness, the forming of the UV coating layer 12 on the top surface of the wood piece body 11, the wood of the finished state When the piece is used for the living room floor as shown in Figs. 1 to 2 or when used for a wooden mat as shown in Figs. 3 to 4, the outer surface of the wood piece is protected so that the upper surface is protected by external conditions. This is to prevent the wood pieces from being damaged.

Subsequently, the process of coating and drying the urethane paint on the upper surface of the UV coating layer 12 formed on the wood piece body 11 by spray coating and drying several times, the urethane to a constant thickness on the upper surface of the UV coating layer 12 As the coating layer 13 is formed, the wood piece is completed, and the wood piece in the state manufactured by the prior art has a structure as shown in FIG. 6.

On the other hand, forming the urethane coating layer 13 on the upper surface of the UV coating layer 12, so that when the wooden mat is made using a piece of wood in the finished state so that the upper surface, which is the exposed part of the outside, appears shiny This is to increase the value of commodities.

However, when manufacturing the wood pieces for the flooring by the conventional method as described above, the thickness of the flooring material of the product that will use the cylindrical solid wood from the beginning (5-6㎜ if the product to be used living room floor, 3-4㎜ if the wooden mat) Since it is cut by the saw to be so that there is a problem that the loss of raw materials as much as the amount of sawdust generated in this process.

In addition, the flooring piece of wood in the finished state is composed of a single united wood as a whole, so if you use it to make a living room floor or make a wooden mat, it may be humid in summer or carelessly lifted water during use. Moisture easily penetrates into the wood pieces, as well as the wood pieces are unified, all of which have the same properties, so that the wood pieces are easily twisted in the middle, and the protruding wood pieces are returned to their original state during the subsequent drying process. Since the user thinks as if it is a defective product from the beginning, there is a problem that the preference of the product by the consumer falls.

The present invention has been made in order to solve the above-mentioned problems, peeled to a thin thickness with a cutting knife while rotating the cylindrical wood and then connected to a wide range at the same time by bonding a plurality of sheets in a laminated state by the adhesive When the product is used in the state that the thickness is made and then it is cut by a cutting saw separately provided to make the floor material length and width of the product to be used again, thereby reducing the raw material cost and using the finished floor material in the product. The purpose is to prevent the wood pieces from being deformed by.

In order to achieve the above object, the present invention provides a method for manufacturing a flooring wood piece, the step of peeling off with a cutting knife so as to be a thickness much thinner than the thickness of the flooring material of the product to be used while rotating the cylindrical wood, and to the thin thickness Cutting the circumferential part of the peeled ranch board with a cutting knife so that the cut surface is in a straight line state, and contacting the plural ranch boards with the circumferential part in a horizontal state to a certain size so that the contact surface is made of synthetic resin. Connecting in an overlock manner by a bond, applying a waterproof bond to a ranch board of a wide size connected by the synthetic resin bond, and then laminating a plurality of sheets so that the total thickness becomes the thickness of the flooring of the product to be used; Pressing the finished pasture board integrally with a heat press to obtain a wide wooden board; Cutting the wood board again with a saw to obtain the length and width of the flooring of the product to be used, obtaining a wood piece body, and sanding the top surface of the wood piece body to smooth the wood piece; Applying a UV coating agent to the upper surface of the piece body several times to form a UV coating layer of a constant thickness, and a step of forming a urethane coating layer of a constant thickness by applying a urethane paint on the upper surface of the UV coating layer is carried out sequentially do.

Hereinafter, the present invention will be described in more detail with reference to the accompanying FIG. 7 as an embodiment.

Attached Figure 7 is a flow chart showing the process of manufacturing the wood piece for the flooring by the method of the present invention, the present invention is a cutting knife to be much thinner than the thickness of the flooring of the product to be used while rotating the cylindrical wood Peeling off to obtain the ranch board; cutting the circumferential portion of the thinly peeled ranch board with a cutting knife so that the cut surface is in a straight line; Contacting the contact surface in a horizontal state so as to have a predetermined size, and adhesively connecting the contact surface by a synthetic resin bond, and applying a waterproof bond to a wide-size pasture board adhesively connected by the synthetic resin bond, and then using the entire thickness. Stacking a plurality of sheets so as to have a thickness of the flooring material; Obtaining a wooden board of a wide size by integrally pressing the same, and cutting the wooden board again with a cutting saw so as to have a length and width of the flooring of the product to be used, thereby obtaining a wooden board body 101, and an upper portion of the wooden board body. Sanding the surface and smoothing the surface; applying a UV coating agent to the upper surface of the wood-treated body piece 101 to form a UV coating layer 102 having a predetermined thickness, and the UV coating layer The step of forming a urethane coating layer 103 of a predetermined thickness by applying a urethane paint on the upper surface of is performed sequentially.

Therefore, the cylindrical wood is rotated by a separate rotating device, so that the thickness of the flooring of the product to be used (5-6 mm if the product to be used in the living room floor, 3-4 mm for the wooden mat) is provided separately so that the thickness is much thinner. When peeled off with a cutting knife, a thin plate of ranch is obtained. The peripheral part of the ranch board thus obtained is cut by another cutting knife provided so that the cutting plane is in a straight line, and then the circumferential parts are arranged in a straight line. After contacting the pasture plate in a horizontal state to a certain size, the contact surface is adhesively connected by the synthetic resin bond, and after a certain time, several pasture plates contacted in the horizontal state are unified with each other by the synthetic resin bond. It is a large sized ranch.

In this way, if a plurality of ranch boards of a wide size is obtained, the waterproof bond is applied to each of the ranch boards of the wider size, and then laminated several sheets of the ranch boards of the wide size so that the overall thickness becomes the thickness of the flooring of the product to be used. Pressing the stacked sheets of pads with a heat press causes the synthetic resin bonds and the waterproof bonds applied to each pads to melt and mix with each other as well as penetrate into the cell tissues of each pads. As the board is integrated with the adhesive, a wide sized wood board is obtained, and the wood board obtained is cut by a cutting saw provided separately so as to have the length and width of the flooring material of the product to be used, thereby obtaining the wood piece body 101.

When the upper surface of the wood piece body 101 obtained in this way is subjected to a smoothing process as a sender, and then the UV coating agent is applied to the upper surface of the wood piece body by a roll coating and dried several times. On the upper surface of the wood piece body 101, a UV coating layer 102 is formed to a predetermined thickness, forming the UV coating layer 102 on the top surface of the wood piece body 101, as described above As described above, when the wood piece of the finished state is used for living room flooring as shown in FIGS. 1 to 2 or when used for a wooden mat as shown in FIGS. It is to ensure that the wood pieces are not damaged even by external conditions.

Subsequently, the process of repeatedly applying and drying the urethane paint on the upper surface of the UV coating layer 102 formed on the wood piece body 101 by spray coating, and the urethane to a predetermined thickness on the upper surface of the UV coating layer 102 While the coating layer 103 is formed, the wood piece is completed, and the wood piece in the state produced by the present invention has a structure as shown in FIG. 8.

On the other hand, forming the urethane coating layer 103 on the upper surface of the UV coating layer 102, when the wooden mat made by using a piece of wood in the finished state as described in the prior art that is the upper exposed portion The purpose is to increase the value of goods by making the surface look glossy.

Therefore, when manufacturing the wood pieces for flooring by the method of the present invention, since the solid wood is peeled off with a cutting knife to a thin thickness to obtain a ranch board and then used in a laminated state, the thickness of the flooring material to be used by the cutting saw as in the prior art Since it does not turn on as much as sawdust does not occur, as well as the loss of raw materials is effective.

In addition, the wood slab for the flooring of the finished state is a structure in which a plurality of thin-walled ranch boards are laminated and bonded, and in the bonded state, adhesive bond is infiltrated between the cell tissues of each ranch board, thereby making a living floor using If you use a wooden mat, even if it is humid during the summer season or if you inadvertently pick up the water during the use process, the moisture does not penetrate into the inside of the wood. The side does not protrude in the middle, so the preference of the product by the consumer is increased.
