Description

Technical Field [0001] The present invention relates to a method for producing a wall and a floor board using plywood,

The present invention relates to a method of manufacturing a plate material using plywood, and more particularly, to a method of manufacturing a plate material by applying pressure to an upper surface of a plywood plate to uniformly pressurize the plywood plate, And to provide a method of manufacturing a wall and floor board using a plywood for enabling to provide a particularly good surface texture.

Generally, it is common to decorate the inside of a building with a general type of flooring or wallpaper to decorate the concrete floor in the indoor floor or wall of various buildings. However, in recent years, In order to enhance the interior walls and floors and to make the entire living space have a natural wood texture, it is becoming common to attach a separate plate to the floor of the room to express the wooden texture of the wood as it is.

These wall and floor boards are mainly used in the living room floor of apartments, single-family homes, indoor walls and floors of offices and schools for the environment-friendly environment, and veneer A plate material affixed to a substrate is mainly used.

The conventional MDF sheet is a MDF (Medium Density Fiberboard) sheet. In the MDF sheet, a melamine impregnated color sheet (hereinafter referred to as " MDF " And a melamine impregnated top and a melamine bottom overregion were superimposed on the upper side and thermocompression was performed by pressing between the upper and lower heating plates.

However, although the conventional reinforced plate using MDF as described above can bring about simplification of the processing of the plate, it provides a method of manufacturing an optimal plate material that compresses heat. However, due to the nature of MDF structure, This structure was very weak against deformation and impact such as swelling of the tissue, and particularly, there was a problem that the thermal conductivity was weak.

In order to compensate for the weakness of the MDF as described above, a steel floor board and a veneer sheet using plywood are used. In the manufacturing method of the steel floor board using the plywood, A high pressure laminate (HPL) top plate in which impregnated grafts, a melamine impregnated surface and a melamine impregnated overgraze are overlapped and thermocompression bonded is manufactured, and the plywood is provided separately from the top plate. Secondarily, Was prepared by applying pressure at room temperature.

However, due to the characteristics of the plywood, the strength of the steel plate using the conventional plywood as described above can bring about improvement in the surface strength due to the characteristics of the heat-compressible top plate in a single process. However, Since the nature of the plywood is such that gas and water vapor are expanded from the inside of the plywood, there is a problem that the gas and water vapor are discharged from the plywood itself because the discharge passage for discharging the gas is not provided and the plywood structure is destroyed. The HPL sheet is processed and processed by an adhesive so that it is required to be manufactured through a plurality of processes, so that the productivity is greatly reduced, and there is a problem that deformation is caused by a difference in compressibility between the HPL plate and the plywood .

In the case of a veneer sheet using plywood, a veneer sheet is adhered to a plywood sheet using an adhesive, followed by thermocompression drying, and the upper side of the veneer is repeatedly subjected to sanding and surface coating Respectively.

However, the veneer sheet using the conventional plywood as described above can improve smooth veneer texture by surface processing for several times, but since it must be manufactured through a plurality of processes, the productivity is extremely limited and the surface strength is weak there was.

In order to solve the above problems, applicant of the present invention has proposed a method for manufacturing a plate material having superior surface strength and high density by press-forming a shape paper, an over-ledge, a veneer, -1299918, which is incorporated herein by reference in its entirety.

However, in the method of manufacturing a laminated board as described above, even if other kinds of laminated boards are formed by three or five ply sheets, the difference in density is different in each part, and when the same compressive force is applied, , In particular, there is a serious problem that even a partial variation in strength occurs.

As described above, in the method of manufacturing the wall and floor board using the plywood of the present invention, it is possible to stably support the plywood through the round bar wave plate during the compression molding of the plywood, and the uniform density It is possible to maintain uniform flatness and to maintain a uniform thickness while maintaining the uniformity of compression molding and to obtain embossed patterns and coating layers on the surface thereof in the course of compression molding, In particular, since lattice-like concavo-convexes are formed on the bottom surface through the round bar wave mirror surface plate, the smooth application of the adhesive agent and the adhesive force are increased in the construction of the plate material
