Description

{Manufacturing method of chip-board}

TECHNICAL FIELD The present invention relates to a chip board manufacturing method, and more particularly, to a chip board manufacturing method that can manufacture a chip board using a coco foot and an eco-friendly adhesive.

Generally, when a product is produced using a log, the range of use is limited due to physical properties of the log, and defects such as organic matter may be generated. At the same time, since the current production volume of wood is limited, various studies have been conducted on the use of efficient wood, that is, the utilization of 100% wood using limited wood, and the result of the research is the present construction / interior / exterior materials, (MDF, PB (Particle Board), OSB (Oriented Strand Board), etc.) which are used in various kinds of wood products.

Of the sheet products currently produced, plywood is a sheet-like product manufactured by cutting a thin single plate from a log, applying resin to each single plate, and then cross-laminating the single plates based on the fiber direction.

Among the other plate products, MDF stands for Medium Density Fiber board, which is a medium density fiber board. It separates the fiber structure of wood and presses the adhesive, presses it with strong pressure, and a medium density plate is produced. It is becoming very heavy as it gets higher, and the formaldehyde ingredient in the adhesive can be detrimental to health and has recently been avoided. These MDFs are made of artificial materials with various thicknesses. When the surface is uniform and smooth, acrylic paint can provide a plastic-like surface, while the biggest disadvantage is chemical bonding, Too. MDF is mainly used for interior decoration mainly, and it can be used as a product that looks like a wooden furniture by attaching a natural veneer on the surface using the advantage of smooth surface.

PB is an abbreviation of Particle Board. It is a kind of recycled material. It is made by cutting wood into small granules, making it into plate by using adhesive, and attaching wood pattern film on the surface. These PBs are used as built-in shelters, sinks, shoehorns, etc. in the home, and they are mainly used as table tops in general restaurants. Because they are made of small granules and lightweight compared to other timbers, However, there is a disadvantage in that a large side of the plate on which the film is stuck is cut and an additional film band is attached to the cut portion.

Korean Patent No. 10-1209916 (Registered on Apr. 11, 2011) discloses a method for producing a plywood, wherein an adhesive is produced by replacing part or all of the extender with a fiber, wherein the fiber separates the fiber from the log, The fibrous material is formed in the shape of a chip in the surface polishing process of the wood-formed member formed by heat-pressing the fibrous material after coating the fibrous material with the adhesive, The fiberboard is a wood coated with an adhesive and has a predetermined length. The fiberboard is coated with an adhesive manufactured by using the fiberboard, and then the end plates are bonded to each other to manufacture a plywood. According to the disclosed technology, it is possible to easily form the plywood by easily joining the single plywood, and it is also possible to improve the tensile force of the plywood by the fiber having the length in the extender, By decreasing the usage amount, the production cost can be reduced and the flowability of the plywood manufacturing cost due to the change of the wheat flour price can be reduced.

Korean Registered Patent No. 10-1150726 (registered on May 22, 2012) can improve the dimensional stability of wood by blocking the absorption and hygroscopicity of wood even when a wood panel is used as a flooring for ondol, and various strengths A method of manufacturing a thermosetting resin-impregnated wood panel capable of significantly improving the performance of a thermosetting resin-injected wood panel. According to the disclosed technique, there are provided a cutting step of cutting a log into a plate; A plate material drying step of drying the cut plate material; A resin curing step of curing the thermosetting resin injected into the plate material; and a processing step of processing the plate material in which the thermosetting resin is cured, wherein the resin inserting step is a step of injecting the plate material A step of injecting a thermoplastic resin into the tank, a step of injecting the thermoplastic resin into the tank, a step of injecting the thermoplastic resin into the tank, a step of injecting the thermoplastic resin into the tank, A resin recovering step of recovering the thermosetting resin existing in the tank when the injection of the thermosetting resin into the plate is completed by the pressing step, and a step of recovering the plate into which the thermosetting resin is injected from the tank And a recovery step.

The conventional method of manufacturing a chip board (that is, a wood panel) as described above has problems in that the supply of wood, which is the main raw material of the chip board, is not smooth and the time from the consumption of living trees to re- The price of the chip board is continuously rising because it is getting caught. To reduce the price, the customer who needs the environment-friendly chip board by using the wood chip or the chemical adhesive (for example, formaldehyde) And since the level of formaldehyde in wood is low, it is difficult to export them to foreign countries. In addition, since it is necessary to manufacture a chip board after making the wood into sawdust, it has the disadvantage of making the wood into sawdust through a lot of processes and providing a small chip board in a long time and in a short time.
