  The present invention relates to a manufacturing method of a decorative board and a floorboard using natural veneer, which will be described in more detail, in expressing and reinforcing the surface of the decorative board or floorboard in a pattern of wood or various designs, conventionally HDF, MDF The decorative board and floorboard were made according to the manufacturing process of HPM (high pressure melamine impregnated paper) or LPM (low pressure melamine impregnated paper) using artificial materials (paper) on the surface of the base material such as PB, plywood, laminated wood, and the like. However, in the present invention, an artificial material (printed paper) is adhered to the adhered surface of the base plate material such as HDF, MDF, PB, plywood, laminated wood, chuck plate, magnesium board plate, chestnut plate, aluminum plate, iron plate, copper plate, and stainless plate. Natural material, that is, natural veneer or fabric, which is a well-being material, is directly cut and glued by various shapes of design, and then laid by placing transparent melamine or transparent phenol-impregnated paper on it and curing the surface at once by high temperature and high pressure. A material preparation step of preparing a natural veneer or cloth and a base plate (bonded surface); A two-stage plastering plate manufacturing process of directly cutting and bonding natural veneer or cloth onto the prepared base plate material (bonded surface); A three-step LPM surface hardening step of reinforcing the surface of the plasterboard, which is plastered on the base plate (adhesive surface), by coating with melamine or phenol-impregnated paper; It relates to a manufacturing method of the decorative plate and floorboard using a natural veneer, characterized in that the manufacturing.

In general, the inconvenience that consumers experience while using office furniture, kitchen furniture, and ondol floors is that the surface of the product (furniture and flooring) is weak due to the surface of the product (furniture and flooring). As it occurs easily, it is a method of reinforcing the surface in order to solve the inconvenience of using the surface material using artificial materials (printed paper) such as HPM (high pressure melamine impregnated paper) or LPM (low pressure melamine impregnated paper). Has been manufactured.

The HPM (High Pressure Melamine Laminate) is used for printing various patterns on paper, dyeing various colors, or simply passing white paper or yellow paper through a container containing melamine resin or phenolic resin. The impregnated sheet is impregnated with phenol, pre-dried and cut into a certain size to make an impregnated sheet.The sheet impregnated with melamine or phenol formed by high temperature and high pressure by being laminated in multiple layers according to the application is called HPM sheet. It is attached to the surface to be bonded (MDF, HDF, PB, plywood, laminated wood, etc.) to manufacture office furniture, kitchen furniture, floorboards and electronic case.

The LPM (Low Pressure Melamine Laminate) is used in the manufacturing process of HPM by making the impregnated sheet in advance and attaching it to the adhered surface of the base material, but the manufacturing process of LPM is different, MDF, HDF, PB, plywood , Put transparent or opaque phenol or melamine impregnated sheet on the surface to be glued, such as laminated wood, put paper or veneer on it, put transparent melamine or transparent phenol impregnated sheet on it, and harden them by high temperature and high pressure at the same time. It is manufactured by the method of processing.

In this way, a pattern of wood is printed on a paper to form a pattern of natural wood, and a melamine sheet is bonded to both sides of these printing papers to form a patterned plate, and then bonded to the surface to be bonded to the substrate to process a manufacturing board or floorboard. However, products made of paper are excellent in scratch resistance, heat resistance, water resistance, and impact resistance, while the HPM and LPM processes use a printed processed material. When the surface was scratched, the white paper protruded, making it a poor quality product, and the surface sanding (smooth polishing) was not possible at all, which made it difficult to make the best texture. In addition, the harmful components printed to express patterns on artificial materials (printed paper) not only generate toxic gases in case of fire, but also adhere to the substrate (adhesive surface) if used for a long time in a humid place. Separation and peeling of the paper part occurred, which shortened the life of the product and caused a problem in the product. In the past, HPM or LPM was difficult to process as natural veneer, and it was difficult to commercially mass-produce due to the uneven surface of tannin, oil and pentosan on the surface of veneer. There were many problems that could not be the right product because of the differences and stains.

Accordingly, an object of the present invention is to devise to improve the various conventional problems as described above, by plastering (cutting and adhering) by directly attaching the veneer or cloth, which is a natural material, to the adhered surface of the base plate material, and then transparent on it By placing melamine or transparent phenol-impregnated paper and hardening the surface at high temperature and high pressure, not only LPM can express the natural texture of natural veneer and wood pattern of various colors, but also durability, aroma and deodorization function, insect repellent function, Functionality such as anion, fouling resistance, flame retardancy can be imparted, and the purpose is to provide an economical and advanced product due to the dramatic improvement in productivity and economical efficiency due to plastering (cutting and bonding).

 The present invention relates to a manufacturing method of a decorative board and a floorboard using natural veneer, which will be described in more detail, in expressing and reinforcing the surface of the decorative board or floorboard in a pattern of wood or various designs, conventionally HDF, MDF The decorative board and floorboard were made according to the manufacturing process of HPM (high pressure melamine impregnated paper) or LPM (low pressure melamine impregnated paper) using artificial materials (paper) on the surface of the base material such as PB, plywood, laminated wood, and the like.

If more detailed description of the configuration of the present invention through the accompanying drawings as follows.

Figure 1 shows a flow chart of the entire process for the manufacturing method of the present invention, in order to process the surface of the decorative plate and floorboards with natural veneer or cloth in the process of manufacturing the decorative plate and floorboards ( A material preparation step 10 of preparing a surface to be bonded 15; A two-step plasterboard manufacturing process 20 for directly cutting and adhering the natural veneer 11, 12, 13 or cloth 14 onto the prepared base plate material (adhesive surface 15); Three-step surface hardening (LPM) process (30) to be strengthened by coating with a transparent melamine or transparent phenol-impregnated paper (30-1) on the surface of the plasterboard 27, which is plastered on the base material (bonded surface, 15) ); As shown in the large three-step manufacturing process.

Step 1: Material Preparation Process

In the material preparation process, the natural veneer of the material to be prepared is a natural veneer (11) that is used without a bleaching dyeing process, and the natural veneer itself alone contains tannins, oils, pentosan, etc. As the surface is uneven and it is not a right product due to staining, it is selected, bleached, washed, and dyed by standardizing veneer.In the 2nd plastering process and the 3rd surface reinforcing work LPM process due to the bleaching process Able to achieve color leveling without stains or color agglomeration on the surface, and prepare natural veneer with improved adhesion, and standardize and set color without stain by performing standard dyeing through water washing after bleaching treatment. Natural dyeing veneer (12) and natural collection according to the difference in the standardization process Consists of a veneer (13), two types of crude veneer (11) for use without going through the process of bleaching stain may be necessary when the cost of production to be prepared as the surface flooring and flooring material of the screen. The base plate material (bonded surface 15) prepared from another material maintains the same color as the natural veneer to be plastered on the surface, and to prevent surface contamination of the veneer, an aqueous or oily alcohol stain having the same color as the veneer to be plastered on the surface. Colorant) and apply it to dry.

Step 2: Plaster  Manufacture process

The two-step plasterboard manufacturing process 20 is made of natural veneer (11) or natural dyed veneer (12) and natural aggregate veneer (13) or fabric (14), which is set by bleaching and dyeing as it is. Plasma (cutting and adhering) 21 on the surface to be bonded at the same time, while undergoing a first cold pressing process 22, which is compressed at a cold pressure of 15 kg / cm 2 at room temperature, the temperature of 120 ~ 135 ℃ and 15 kg The process of primary aging (26) after cleaning (25) through the process of sanding (24), which reduces the plastering plate by the secondary thermopress press (23), which is hot pressed at a pressure of / cm2, and smoothly polishes the surface. Up to two stages of plasterboard manufacturing process (20).

Step 3: Surface Reinforcement LPM fair

In the three-step surface hardening LPM process, a transparent melamine or phenol-impregnated sheet was placed on the surface of the plastering plate manufactured in the second step, and the third high temperature and high pressure press process (31) was carried out at a temperature of 165 ° C. to 180 ° C. at 40 kg / cm² pressure. Compression set for seconds. At this time, according to the thickness of the transparent melamine or phenol-impregnated paper impregnated, the eyes of the tree are alive and the grain of the open pore LPM or the eyes are completely filled with cross-pore LPM coating expression, which enables the production of high-quality products.

Thus, the finished boards and floorboards that have been finished to the surface reinforcement are aged for a second time (32) for more than a week, so that even after cutting and grooving or edge processing, they can produce the boards and floorboards without defects such as bending or warping. Can be.

Hereinafter, in the present embodiment will be described in detail with reference to Figures 2, 3 and 4, the configuration of the two-step plastering manufacturing process 20 and the three-step surface strengthening,

[ Example  One] Plaster  Manufacturing method and 3 step surface reinforcement

Figure 2 is as shown in the cross-sectional view showing an embodiment of the present invention for preparing a plastering plate,

2) is a cross-sectional view showing a method of manufacturing a plastering plate of the present invention, HDF, MDF, PB, plywood, laminated wood, drain plate, magnesium board plate, chestnut plate, aluminum plate, iron plate, copper plate, stainless steel plate, etc. Of the same base plate material (bonded surface 15), any one of the base plate material 15 and the natural veneer (11) or natural dyed veneer (12) or natural aggregated veneer (13) or fabric (14) bleached and dyed. Any one of them is prepared for plastering (cutting and bonding), and then plastered as a structure as shown in FIG.

FIG. 3 is a cut and sawed natural veneer 11, 12, 13 or cloth 14 to the required dimensions, as shown in 1) of FIG. 3 in accordance with a plan view of an embodiment of a plastered structure of the present inventor veneer or fabric. By passing through this mark (21-1), the yield is increased, and the base plate material (bonded surface, 15) by overlapping (21-3) in such a manner as to face the veneer cut to the standard as shown in 2) of FIG. 3) of FIG. 3 while neatly treating the seams of the natural veneer or cloth cut while cutting the portion of the overlapped 21-3 by applying a cut 21-4 to the center of the overlapped 21-3 while adhering to Like vertical, horizontal or mosaic type, block type, any type of natural veneer (cloth) can be formed in a variety of designs, the base material (bonded surface, 15) to the natural veneer (11, 12, 13) or cloth At the same time as the (14) is cut and subjected to the primary cold press process (22) to compress by cold pressure hardener ( 21-5) without need Temporarily aged in temporary temporary temporary adhesion state under cold pressure, secondary bond bonding at 15kg / cm² pressure by press through second pressurization (23), and fully matured. To increase the specific gravity. In addition, HDF has better surface strength than MDF because it is reduced at high temperature and high pressure during molding, and the rigidity of the base plate material (bonded surface, 15) is also very important. It is very important to maintain the abnormality, and if the specific gravity is less than 0.6, it is very important to increase the surface hardness of the product by shrinking the veneer through compaction when plastering. Therefore, since the difference in the rigidity of the veneer is proportional to the surface strength and the scratch resistance of the final finished product, it is very important that the secondary thermopress press 23 for hardly reducing the veneer to pressure.

At the time of plastering, the adhesive 21-2 is plastered with an adhesive 21-2 made by combining melamine co-condensation resin and starch (powder) without using a polyvinyl acetate (PVAc) adhesive. Temporary primary temporary adhesion by primary cold press working (22) at a pressure of 15㎏ / ㎠ and maintain the temperature 120 ° C ~ 135 ° C higher than the curing temperature 80 ° C ~ 100 ° C of general urea resin Secondary thermo-pressure press processing using heat medium boiler for heat treatment enables curing without hardener (21-5), and thus transparent melamine or transparent phenol impregnated sheet (30- 1) When the secondary aging (32) by bonding can be properly aged without poor adhesion or puncture. The absence of poor adhesion or popping means that the polyvinylacetate (PVAc) and the urea components in three stages are used when plastering using adhesives that combine polyvinylacetate (PVAc) and urea resin. There was a problem that the product burst due to poor adhesion because the melamine which is a component of the melamine transparent impregnation impregnated when the surface is strengthened. A hardener (ammonia chloride solution, 21-5) on the adhesive 21-2, in addition to the method of bonding the veneer plastered on the base material (bonded surface 15) by pressure using only cold pressure and heat pressure without using the adhesive 21-2. Placing natural wood veneer (11, 12, 13) or fabric (14) on the base plate material (bonded surface) through only cold pressing 15kg / cm² Cutting and gluing), it is possible to produce a decorative board or floorboard without crushing or bending (bending or warping), and with a mixing mixer having a wrong ratio between the components of the adhesive 21-2, In order to prevent the banding (bending and warping) of 15), 85% by weight of melamine co-condensation resin and 15% by weight of starch (flour) are mixed and mixed on both sides of the base plate material (adhesive, 15), and At this time, if the coating amount is large, the adhesive 21-2 Contaminate the machine going out or veneer surface and doemeuro workability is deteriorated but later than the adhesive coating film 150g per m² in order to prevent the soteum and prevent contamination of the adhesive. Due to the addition of the curing agent as described above, as the adhesive is completed only by the first cold pressing process without the secondary hot pressing process, as shown in 2) of Figure 2 has a feature that can be compressed at the same time by stacking multiple sheets.

Plastering plate that has undergone the first cold press process 22 and the second hot press press process 23 so that the transparent melamine or transparent phenol impregnated sheet 30-1 can be well impregnated during the three-step surface hardening LPM process. The sanding (24) operation to smooth the surface is repeated several times to help strengthen the surface. In the HPM and LPM process using artificial materials, sanding (24) was not possible at all, but sanding (24) was made by laying natural veneer (11, 12) or fabric (14) on the substrate (adhesive surface 15) in advance. The ability to keep the surface clean and smooth over and over again is a prerequisite for high quality, and sanding (24) is a very important point, especially for veneer and fabric. As a result, it is easy to upscale and standardize quality, such as scratch resistance, scratch resistance, and abrasion resistance, which is incomparable with products made of paint, and also to mass production. Especially, LPM made of artificial material (printed paper) In this case, the veneer should be made 4'X 8 'or 5'X 8' but the width of the veneer is 0.5 'to make the side joints 4' (1240mm) wide because the width is not constant. Work can be done when it is more than mm, but if you use plastering, the thickness of veneer should be 0.2mm and narrow veneer can be used. Therefore, sanding (24) several times using thin veneer (0.2mmT) of thin veneer (0.2mmT), which is impossible in HPM and LPM manufacturing process, and transparent melamine or phenol-impregnated paper (30-1) in a thinner 0.15mmT thickness Since it can be combined with the high strength wear resistance and scratch resistance is further guaranteed. After a number of sanding (24) operation is performed, the cleaning (25) to remove the dust or foreign matter that is ejected when the grinding is carried out, the plastering plate made by the two-step plastering manufacturing process (20) is three steps The surface reinforcement LPM process 30 compensates for the problem of poor adhesion or popping during the compression of the third high temperature and high pressure, and provides a sufficient cooling time for one week or more to undergo a two-step plastering manufacturing process through the first aging step (20 ) Will be made.

When making veneer (cloth) LPM on hard adhered surface such as HDF by the above-mentioned plastering plate manufacturing process, the back veneer (cloth) of hard base plate material (bonded surface) such as HDF should be at least 0.15 ~ 0.2mm thick. In addition, the front veneer should be 0.15 ~ 0.2mm thick to solve the banding and whitening of the front surface of the product. In addition, maintaining the smoothness of the high-pressure press is an important point for correcting the whitening phenomenon, so it is very important to replenish the thickness of the outer portion of the press, which has been thinned by continuous use.

 Figure 4 shows a cross-sectional view of a method for strengthening the surface of the plasterer of the present invention, the third high temperature and high pressure to the third compression and the transparent melamine or transparent phenol-impregnated sheet (30-1) on the surface of the prepared plastering plate The press working 31 is compression set for 50 seconds at a pressure of 40 kg / cm² at a temperature of 165 ° C to 180 ° C. At this time, open pore LPM expresses the tree's eyes when it is 30g ~ 50g per m² depending on the thickness of the transparent melamine or phenol impregnated paper impregnated. Due to this, it is possible to produce high-quality products, and the finished board and floorboards that are finished until the surface reinforcement are aged for a second time (32) for more than a week, so that defects such as warpage and warping are eliminated even in the next step of cutting and grooved processing or edge treatment process. It can produce vanity boards and floorboards.

As described above, although the present invention has been described above, it is not necessarily limited thereto, and various modifications may be made without departing from the scope and spirit of the present invention.

The above-described configuration and the present invention relates to a natural veneer (cloth) LPM (cosmetic and floorboards) manufacturing method, LPM by using a natural veneer, natural dyed veneer, natural aggregate veneer, cloth, not printed paper It is possible to produce natural, high-quality, differentiated customer satisfaction products that seemed impossible in the industry.In addition, the use of dyed veneer for the standardization of color and the use of aggregate veneer for the standardization of color, pattern, and standard are applied to the LPM of veneer or cloth board. It is possible to bring about a revolution. Especially, if you use natural veneer without bleaching or dyeing veneer, you can produce natural texture of natural veneer at economic cost because you can produce low quality but low quality without standardization of color. Can be provided to In particular, the veneer HPM and veneer LPM can be used only when the width is connected, and the crumpled surface is not available, whereas only the flat and clean veneer is used, whereas the plastering veneer LPM of the present invention has a narrow width as well as the veneer veneer of the present invention. Wood veneer can also be used, resulting in superior cost savings and mass production.
