The present invention relates to a method for manufacturing floorboards using bamboo, and more particularly, to a method for manufacturing floorboards using bamboo, which is harmless to the human body, has excellent strength, sterilization and insect repellent effect, and has a small depression factor.

In general, floorboards are used as the flooring of the living room, such as apartments or detached houses, as well as the interior floor of the office, when constructing a plurality of floorboards on the floor surface in the length and width direction to have a mosaic arrangement as a whole.

In recent years, due to the high quality of apartments and detached houses, the interest in indoor interiors has increased, and in most cases, natural-friendly floorboards are used as floor coverings when installing living rooms or floors. In addition to the rapidly increasing trend, the development of related technologies is also in progress.

One embodiment of the conventional floorboard material is made of a single united tree, the other embodiment is made by adhering a pattern plate made by turning the wood thinly on the upper surface of the plywood, the floorboard material of the conventional embodiment As described, there are several problems because the whole consists of a single tree.

In other words, the wood used as floorboard is a special species (strong maple, beech, etc.) that is strong, grainy, and calm in color, and has to be received for several decades. Price is soaring when supply and demand are imbalanced. This is happening, and due to various reasons that the non-commercial part like the knot part of the whole wood takes up a lot, there is a problem that it is not popularized as the price of the product increases and the product is used only by some rich people. If the thickness of the floorboard material is a little thin to reduce the cost, when the wood is dried after construction, the whole property is the same and has the same bending property in the same direction. In order to make the whole thickness thicker There is a problem (weight increase of material cost, weight increase, etc.).

In view of various problems of the above-described embodiment, a floor board material which is very popular at a low price is provided in another embodiment, and the floor board material of another embodiment is constructed by bonding a thin plate turned on to a low-cost plywood. In the state, only the pattern plate is displayed to the outside, so that the visual impression of the user is like a floorboard made of a single expensive wood, as in one embodiment, which can produce a low price product by reducing raw material costs. Of course, the plywood, which is one of the components, is bent to one side by drying in the process of use after construction, even though the overall thickness is not thicker than necessary, considering that a plurality of sheets of thinly lit sheets are irregularly bonded in various directions. This does not happen and is popularly used.

Then, when looking at the floorboard material of another conventional embodiment in detail by FIG. 1 there is a rectangular plywood 100 having a suitable size, the one side long side and one side short side of the plywood 100, the insertion protrusion 200 for assembly In addition to the other side is formed on the other side of the long side and the other side of the short side insertion groove 300 is formed for assembly, the upper surface of the plywood 100 is bonded to the thin plate-like pattern plate 400 is turned on thin The surface protection layer 500 is formed on the upper surface of the pattern plate by applying a UV coating material or a urethane coating material.

The manufacturing process of the floorboard material according to another embodiment configured as described above will be described in more detail. A plywood of appropriate size in the form of a rectangular plate having a length of about 90 cm and a width of about 8 cm in a thickness of 6 to 8 mm. (100) is obtained by the processing, and apart from the plywood, the thickness and the width and the length and width of the same size as the plywood 100, respectively obtained by processing the patterned plate (400) and then the plywood (100) The insertion protrusion 200 is formed on one side of the long side and one side of the short side, and the insertion groove 300 is formed on the other side of the long side and the other side of the short side.

After the adhesive is applied to the upper surface of the plywood 100, and then lightly put the pattern plate 400 over the adhesive, by pressing and heating it for a predetermined time by a heat press for the pattern plate 400 by the adhesive After adhering to the plywood 100, the top surface of the patterned plate 400 is subsequently smoothly processed using a sender, and then the UV coated or urethane coating is applied several times by roll coating to the coated surface, followed by drying. After the process, the floorboard is manufactured.

On the other hand, the floorboard manufactured by the above process may form a plurality of insertion grooves to form a checkerboard while crossing the horizontal and vertical direction to the bottom surface of the plywood, which is the floorboard when the floorboard is manufactured on the floor The adhesive material for fixing the plate (epoxy, etc.) is to enter the insertion groove to improve the fixing force, the operation of forming a plurality of insertion grooves on the lower surface of the plywood in consideration of the operator's convenience It is not necessary to fix it in any particular order because the order is determined, but it is better to perform it immediately after the plywood is provided in the preferred order or immediately after forming the surface protection layer on the upper surface of the pattern plate. do.

However, such a floorboard material is a structure that is adhered to the upper surface of the plywood with a thin thickness turned on the structure is inexpensive in terms of price, but the long-term use of the pattern plate is often peeled off partly because there is a problem that a lot of maintenance costs Of course, when partially repaired, the color of the part did not fit well with other parts (discoloration or color difference), which was unsightly in view.

In addition, most floorboards produced so far have to be limited to patterns placed on wood and pattern boards. From the user's point of view, almost the same pattern is visually repeated in any house or office. There was a problem that the user's preference for the product is gradually falling.

The present invention has been made in view of the above problems, the object of the invention is to solve the above-mentioned problems, the relatively low price of bamboo processing by the side, while the surface is strong and green tea and salt penetrates into the pores of bamboo It is an object of the present invention to provide a method for manufacturing a bamboo floorboard material, which makes it hard to be easily deformed by the external environment by making the rigidity and strong properties of the bamboo flexible.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Figure 2 is a process diagram showing the manufacturing process of the present invention and Figure 3 is a bamboo floorboard material produced by the method of the present invention according to the present invention firstly the upper plate 12 and lower plate 17 and the intermediate plate 11 By manufacturing the intermediate plate 11 is installed between the upper plate 12 and the lower plate 17 to form a floor board material, but the upper plate 12, the lower plate 17 is the same manufacturing method and in the case of the intermediate plate 11 The manufacturing method is the same, but the difference only in the thickness and the upper surface of the top plate 12 is a natural lacquer coating layer 16 is formed.

Detailed manufacturing method of the floorboard material of the present invention is a seven-year-old wood felling 60cm or more in diameter and dried in the natural state (see S10), after the drying process the wood with a diameter of 60cm or more in the width of 1.8cm bamboo pieces ( 15) (see S20).

Bamboo flakes (15) formed by the sculpting cutting process to naturally dry for 7 days to breathe bamboo breath (see S30), water 10t green tea solution 1t, salt 2t with respect to 10t of bamboo pieces (15) after the second drying process After the bamboo pieces (15) are completely immersed in the mixture of the mixture and aged for 24 hours at a high temperature of 100 ℃ or more (see S40).

The reason for using the green tea solution and salt in the aging process (S40) is to penetrate into the pores of bamboo and act as a catalyst to soften the rigidity and strong properties of the bamboo, making it easy to install on the floor when the product is finished after construction. This is to prevent distortion and defects in advance.

On the other hand, after removing the moisture and moisture from the steamed bamboo made by the aging process (S40) in the shade (see S50) and after the third drying process (S50) to inspect the moisture content of the bamboo pieces (15) or less set water content Perform a water measurement process (S60) to select only.

At this time, the moisture content of the measured bamboo pieces 15 should be less than 2%, and when the moisture content is 2% or more, bad treatment is performed, and the bamboo pieces passed as a result of the moisture measurement are dried for 10 days in the shade (see S70).

In addition, after the fourth drying process (S70) by horizontally pasting bamboo carved into 1.8cm in width is 610cm in length, the upper plate is 2mm thick, the middle plate is 5mm thick, the lower plate 17 is processed so that the thickness is 2mm ( S80), and compresses the bamboo disc prepared according to the above specification into a piece of 1.8cm bamboo by applying a compression time of 400 hours at 400t pressure for 48 hours. (See S90.)

After the compression process using the Lutheran machine to check the deformation and defects (see S100) and then cut the disk to 92mm in length, 75mm in width, 9mm in total thickness, and then the top plate 12, intermediate plate 11, lower plate 17 in order Laminated and bonded together.

The installation form of the upper plate 12 and the lower plate 17 is the same as the arrangement of the bamboo pieces 15, as shown in Figure 3 attached to the middle plate 11 is the floor arrangement in the form of cross-border to cross the arrangement Forming the structure of the upper plate, the middle plate, the bottom plate is formed in the order of the top and bottom, and the bottom plate the back side of the bottom plate 이루어진 made of the processing and the projection 200 is processed (see S110).

Grinding the surface of the material through the cutting process (S110) to perform the best surface precision machining (see S120), five times machining and at least one time processing, and the lacquer on the surface of the precision processed product Paint the oral solution several times repeatedly (see S130).

The reason for performing the lacquer several times as described above is to form a predetermined coating layer 16 and the reason for forming the coating layer 16 in natural lacquer is to allow the bamboo to breathe.

On the other hand, the natural lacquer coated product is transferred to a maturation chamber and dried naturally in the shade (see S140), and after the fifth drying process (S140), one product is inspected with a yuan and the color and the horizontality are examined. If it does not meet the standard during visual inspection, it is processed by defective treatment and manufactured in the order of packing process (see S160) to automatically package the finished product.

The present invention manufactured by the above method is processed by relatively low price bamboo side, while the surface is strong, green tea and salt penetrates the pores of the bamboo to soften the rigidity and strong properties of the bamboo, easily deformed by the external environment There is an effect to prevent that.
