Description

TECHNICAL FIELD [0001] The present invention relates to a method for manufacturing a flooring material using plywood,

The present invention relates to a method for manufacturing a floor material using plywood and a floor material thereof. More particularly, the present invention relates to a method for manufacturing a floor material using MDF, The present invention relates to a flooring material manufacturing method and a flooring material using the plywood capable of producing a continuous operation of a flooring having a connecting projection and a connecting recess.

In general, the flooring material is constructed to cover and decorate the concrete floor which is constructed on the indoor floor of the building, and to have a natural wood texture effect as a whole while producing a luxurious indoor atmosphere.

In addition to the development of plywood manufacturing technology, the utilization of logwood has been enhanced and many plywoods having excellent physical properties have been provided. In the processing of logs, the logs are not cut directly from the logs and the logs are cut round, A thin sheet is cut and laminated by a method in which the resultant is arranged in a direction perpendicular to each other, and the sheet is laminated to each other with an adhesive or the like to form a plate having a constant thickness.

By doing so, the plywood does not have a certain direction of orientation as compared with the wood plate having the texture, so that there is almost no distortion, and the endurance and the like are improved in all directions.

However, the plywood processed by this method has a problem that the decoration property is deteriorated because there is no texture of the wood itself due to its processing characteristics.

Therefore, when such plywood is used for flooring materials such as flooring or other building materials, the surface is decorated with veneer and the surface thereof is coated with a resin coating so as to be resistant to water resistance and scratching .

As an example of manufacturing this kind of indoor flooring, there is a method of manufacturing a flooring material by bonding a veneer single plate to the upper surface of a plywood with urea resin.

Particularly, in order to improve the appearance effect, the surface of the veneer is ground with a brush or the like, and then the appearance and effect are improved by coloring and surface treatment.

However, such a manufacturing method has a disadvantage in that it is difficult to form the desired thickness of the veneer to a desired thickness, and the resistance to water and heat is very weak.

Particularly, a flooring material using such a veneer has a problem that discoloration, scratching, and deformation due to moisture occur when it is used.

In order to solve the above problems, a flooring material has been developed. The flooring material according to the related art has a base layer composed of any one of MDF, HDF and plywood, and an adhesive layer laminated on the upper surface of the base layer. And a printing layer formed by embossing in an embossed state.

BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Laid-Open Publication No. 10-2014-0091277 (published on Jul. 21, 2014, title of the invention: flooring material and its manufacturing method).

The flooring material according to the related art has a problem that it can cause the interlayer noise when it is applied to the indoor floor of the apartment house because the flooring material according to the prior art does not have a separate technical structure for buffering action.

In addition, since the flooring material according to the prior art does not have a separate technical structure for connecting a plurality of flooring materials to each other, there is a problem that a gap may be generated between the flooring material and the flooring material when a plurality of flooring materials are successively applied .

Therefore, there is a need for improvement.

The present invention relates to a method of manufacturing a flooring using a MDF, which can prevent floor-to-floor noise by canceling the impact applied to the floor of the room, reduce heat loss, A method for manufacturing a flooring material using the same, and a flooring material thereof.

The second mold 50 is seated on the second mold 50, And a finishing block 74 that is seated on the upper surface of the third mold 70 so as to close the molding hole 72. [

The third mold 70 is lifted or lowered by the operation of the lifting drive unit 86 so that the third mold 70 is raised so that a gap is formed between the second mold 50 and the third mold 70 The panel member 12 can be inserted into the seating groove 32 at a distance between the second mold 50 and the third mold 70.

The second mold 50 includes a first block 58a which is seated on the upper surface of the first mold 30 and curved in an 'C' shape and a second block 58b which is disposed adjacent to the first block 58a And a second block 58b bent in an 'a' shape so as to form the mounting hole portion 52.

The first block 58a and the second block 58b are each formed with an inclined surface 54 at an outer corner to connect the spacing drive unit 80. The spacing drive unit 80 is disposed on the inclined surface of the first block 58a And a second spacing cylinder 84 connected to the slope 54 of the second block 58b.

When the rod is projected from the first spacing cylinder 82 and the second spacing cylinder 84, both end portions of the first block 58a and the second block 58b are closely attached to each other and a rectangular embossing hole portion 52 .

When the rod is projected from the first spacing cylinder 82 while both ends of the first block 58a and the second block 58b are in close contact with each other and the rod is inserted into the second spacing cylinder 84, The entirety of the second mold 50 protrudes to the outside of the first mold 30 and the third mold 70 while the both ends of the second block 58a and the second block 58b are kept in close contact with each other, The hole portion 72 and the mounting hole portion 52 are separated from each other.

When the second mold 50 is moved in the lateral direction, grooves for forming the connecting protrusions 22 are formed on the two side surfaces of the central portion of the work space in which the urethane foam resin is filled, The connection groove portion 24 is formed.
