It may be a two-component type in which a curing agent for curing the urethane is mixed.

Here, the non-segmented type polyurethane resin means a well-known polyurethane resin which has little fluidity and is used as a sealing agent.

The sealing layer 130 may be formed to have a thickness of approximately 0.5 mm to 1 mm.

As shown in FIG. 1, the floor construction method having the embossed layer 150 using a non-MOCA type polyurethane according to an embodiment of the present invention may include forming a reinforcing layer 140 (S40). have.

Since the reinforcement layer 140 has a higher density than the elastic layer 120 and has a higher hardness than the elastic layer 120, the reinforcement layer 140 may prevent the elastic layer 120 from being easily damaged from an external force. It may be formed of a urethane resin to provide some elastic force.

The reinforcement layer 140 may be formed to have a thickness of 2 mm to 4 mm or less.

At this time, the organic solvent may dissolve the non-segmented type polyurethane in order to smooth the workability in consideration of the influence of the temperature and humidity of the outside in the state of stirring the main agent and the curing agent.

The organic solvent mixed with the non-segmented type polyurethane resin to form the emboss layer 150 may be mixed with 0.5% or more and 3% or less with respect to the total weight of the non-segmented type polyurethane resin.

Here, when the organic solvent exceeds 3%, the embossed shape formed by the fluidity of the non-segmented type polyurethane resin is easily collapsed, and it is difficult to maintain the embossed shape, and when the organic solvent is mixed below 0.5%, the non- There is a problem in that workability is poor due to the viscosity of the shegging type polyurethane resin and it is difficult to form an embossed shape.

That is, when the embossed layer 150 is formed, when the organic solvent is mixed at 1% or more and 3% or less, the workability is slightly lower due to viscosity, but the embossed shape can be maintained and cured while curing.

The organic solvent may be implemented with either toluene or solvent.

Meanwhile, when the emboss layer 150 is formed, rubber chips may be mixed to form an emboss shape. When rubber chips are mixed, the rubber chips emboss layer 150 according to elastic deformation. It is preferable to form the embossed shape only by the viscosity of the non-segmented type polyurethane resin without using a rubber chip because it is easily eliminated.

As shown in FIGS. 3 to 6, the embossing apparatus 200 may easily form an embossing shape using a non-segmenting type polyurethane resin having a relatively high viscosity.

The embossing apparatus 200 may include a uniform coating member 210, an embossing roller 220, and a handle 230.

The uniform coating member 210 may apply a non-segmented polyurethane resin dissolved in an organic solvent to have a uniform thickness.

Non-segmented type polyurethane resin may be applied so as to have the same thickness as the depth of the tooth groove 211.

The uniform coating member 210 may include a thickness adjusting member 215.

The thickness adjusting member 215 may be overlapped with the thickness adjusting member 215 to adjust the thickness of applying the non-segmenting type polyurethane resin.

The thickness adjusting member 215 may be formed in the shape of a plate, and may overlap the thickness adjusting member 215.

In addition, the thickness adjusting member 215 is installed to be slidably moved up and down in the uniform coating member 210, the non-segment type polyurethane resin to be applied according to the height that the thickness adjusting member 215 covers the tooth groove 211. The thickness of the can be adjusted.

At this time, the guide portion 213 for guiding the vertical movement of the thickness adjusting member 215 may be formed on both sides of the uniform coating member 210.

The thickness adjusting member 215 may be provided with a fixing member 217 for fixing in the state of adjusting the thickness by the tooth groove 211, the uniform coating member 210 is adjusted according to the thickness adjusting member 215 A scale indicating the thickness to be applied may be displayed.

The embossing apparatus 200 may include an embossing roller 220.

The embossing roller 220 may form an embossing shape while passing through the non-segmenting type polyurethane resin applied by the uniform coating member 210.

The embossing roller 220 may form an embossing shape in such a manner that the non-segmenting type polyurethane resin protrudes into an arbitrary shape when the embossing roller 220 is rotated by the adhesiveness of the non-segmenting type polyurethane resin. .

The embossing roller 220 may include a roller body 221, a rolling pin 223, and an embossing member 225.

The roller body 221 may be formed in a cylindrical shape, the through hole for the rotary shaft is fitted at both ends of the roller body 221 may be formed.

And, the outer surface of the roller body 221, the plurality of rolling pins 223 may be formed along the circumference, the plurality of rolling pins 223 are spaced apart along the longitudinal direction of the roller body 221 to be installed Can be.

The rolling pin 223 may rotate the roller body 221 spaced apart from the reinforcing layer 140 positioned below the embossing layer 150 to form an embossing shape.

The rolling pin 223 is formed in the shape of a pointed pin end to form a pin groove 141 in the reinforcement layer 140 is located in the lower portion of the embossed layer 150 in accordance with the rotation of the roller body 221, pin groove ( As the non-segment type polyurethane resin forming the emboss layer 150 in the 141 flows into the pin groove 141, the emboss layer 150 may be easily prevented from being peeled off from the reinforcing layer 140.

The embossing member 225 may pass through the non-segmented polyurethane resin wound around the roller body 221 to be coated, and the non-segmented polyurethane resin may be accompanied by adhesiveness due to viscosity to form an embossed shape.

The embossing member 225 may be formed of a material having chemical resistance to an organic solvent, and the embossing member 225 may be formed of a material having porosity in the form of a nonwoven fabric.

The thickness of the embossing member 225 may be formed to have a thickness smaller than the length of the cloud guarantee pin 223 so that the rolling pin 223 protrudes through the embossing member 225.

Here, when the embossing member 225 is the same as the rolling pin 223, the non-segmented polyurethane resin applied by the embossing member 225 in contact with the reinforcing layer 140 is pushed, the applied portion is not As applied, the reinforcement layer 140 may be directly exposed to the outside.

Accordingly, the rolling pin 223 protrudes further through the embossing member 225, so that the embossing member 225 does not directly contact the reinforcing layer 140 when the embossing roller 220 rotates. Since the embossed shape is formed while contacting the upper surface of the polyurethane resin, it is possible to prevent the reinforcement layer 140 from being exposed to the outside as it is uncoated.

In addition, since the viscosity of the non-segmented polyurethane resin forming the embossing layer 150 is high, the embossing roller 220 may not be easily rotated by adhesiveness, so the rolling pin 223 may have the reinforcing layer 140. To form a pin groove 141, it is possible to prevent the rotation of the embossing roller 220 by the viscosity by applying a non-segmented polyurethane resin.

On the other hand, the embossing roller 220 is located in the rear of the uniform coating member 210 with respect to the application direction to apply the non-segmented polyurethane resin uniform coating member 210 to a uniform thickness first, immediately embossing roller 220 may be configured to pass through to form an embossed shape.

For example, when the uniform coating member 210 is rotated downward from the handle 230, the uniform coating member 210 is applied to the non-segmented polyurethane resin in a uniform thickness and at the same time embossed in the rear Although the emboss is formed while passing through the non-segmented polyurethane resin to which the roller 220 is applied, the uniform coating member 210 is spaced apart from the bottom when the uniform coating member 210 is rotated upward from the handle 230. The coating operation can be performed only by the embossing roller 220.

And, at the end where the handle 230a of the handle 230 is located, the lever 233 for moving up and down the handle 230 to move the uniform coating member 210 up and down may be installed, the lever ( 233 is connected to the connecting rod 219 of the uniform coating member 210 by the wire 235 pulls the lever 233 located in the handle 230a, the wire 235 is a portion where the handle 230a is located Pulled by the uniform coating member 210 may be configured to be spaced apart from the floor.

When the 237 is installed to release the lever 233 from the handle 230a, the uniform coating member 210 may be configured to be in close contact with the floor by the elastic force of the elastic spring 237.

Here, the fixing clamp 239 for fixing the lever 233 to the handle 230 in the state in which the uniform coating member 210 is rotated to the top so as not to touch the floor is installed uniform coating member 210 to the top Even if the lever 233 is not held in the rotated state, the uniform coating member 210 may be fixed while being rotated upward.

The embossing apparatus 200 configured as described above pushes the handle 230 in the direction in which the non-segmented polyurethane resin positioned in front of the uniform coating member 210 is positioned, while the uniform coating member 210 passes, The non-segmented polyurethane resin is applied to the upper surface of the reinforcing layer 140 to have a uniform thickness through the tooth groove 211, and immediately after the embossing roller 220 rotates, the non-segmented polyurethane resin The embossed layer 150 can be easily molded in the form of forming an embossed shape in the.

On the other hand, when the embossing roller 220 is rotated, the rolling pin 223 is stamped on the reinforcing layer 140 to ensure that the embossing roller 220 is not rotated by the viscosity of the non-segmented polyurethane resin, As the non-segmented polyurethane resin flows into the pin groove 141 formed in the reinforcement layer 140 by the cloud guarantee pin 223, it is cured to prevent the emboss layer 150 from being easily peeled off from the reinforcement layer 140. Can be.

In addition, the rolling pin 223 is the embossing member 225 is spaced upward from the reinforcing layer 140, when the embossing roller 220 is rotated, the embossing member 225 is in direct contact with the reinforcing layer 140. To prevent the non-segmented polyurethane resin from being pushed out and the uncoated portion to occur, and the embossing member 225 rotates together with the embossing roller 220 in contact with the upper surface of the non-segmented polyurethane resin. The embossed shape can be formed.

In addition, the thickness adjusting member 215 overlaps the uniform coating member 210 to partially cover the tooth groove 211 formed in the uniform coating member 210, thereby controlling the thickness of the non-segmented polyurethane resin.
