Hereinafter, preferred embodiments of the present invention and physical properties of the respective components will be described in detail with reference to the accompanying drawings. However, the present invention is not limited thereto, And this does not mean that the technical idea and scope of the present invention are limited.

The polyurethane coating mat for floor having excellent impact resistance and sound insulation according to the present invention comprises a buffer layer 10 formed by laminating a plurality of foamed sheets, a surface layer 20 formed on the upper surface of the buffer layer 10, And a bottom layer 30 formed on the lower surface of the base 10.

The buffer layer 10 is formed of foamed polyethylene or ethylene vinyl acetate foam and has a thickness of 12 to 20 millimeters. The buffer layer 10 includes a first buffer layer 11 having a thickness of 2 to 4 millimeters, A second buffer layer 12 formed on the upper surface of the first buffer layer 11 to a thickness of 6 to 8 millimeters and a third buffer layer 12 formed on the upper surface of the second buffer layer 12 to a thickness of 2 to 4 millimeters And a fourth buffer layer 14 formed on the upper surface of the third buffer layer 13 to a thickness of 2 to 4 millimeters.

As described above, the first buffer layer 11, the second buffer layer 12, the third buffer layer 13, and the fourth buffer layer 14 preferably exhibit an expansion ratio of 20 to 40, and the first buffer layer The buffer layer 10 composed of the first buffer layer 11, the second buffer layer 12, the third buffer layer 13 and the fourth buffer layer 14 is formed in a quadruple structure and exhibits excellent buffering effect when an external impact is transmitted to the mat The present invention also provides a floor mats having improved smoothness and shape stability compared to a conventional floor mats in which the buffer layer 10 has a single layer and exhibits an effect of rapidly restoring the shape of the mat after impact transmission.

At this time, when the expansion ratio of each layer constituting the buffer layer 10 is less than 20 times, the buffering effect of the floor mat is lowered. When the expansion ratio of each layer constituting the buffer layer 10 exceeds 40 times, The restoring force and sound absorbing effect of the mat are lowered.

The surface layer 20 is formed on the upper surface of the buffer layer 10 to a thickness of 0.8 to 1.2 millimeters and includes a film layer 21 made of a polyethylene film and a print layer (not shown) formed on the upper surface of the film layer 21 22 and a coating layer 23 formed on the upper surface of the printing layer 22.

The film layer 21 is interposed between the fourth buffer layer 14 and the print layer 22. Since the fourth buffer layer 14 is formed of a foamed material, It is difficult to form the print layer 22 having various patterns because the ink easily penetrates and the film layer 21 made of a polyethylene film which is the same material as the fourth buffer layer 14 is formed on the upper surface of the fourth buffer layer 14 And the printed layer 22 is formed on the surface of the film layer 21, it becomes possible to produce a floor mat having various patterns.

In addition, since the film layer 21 is made of polyethylene or ethylene vinyl acetate exhibiting thermoplasticity, which is the same material as the fourth buffer layer 14, the film layer 21 can be thermally adhered to the fourth buffer layer 14 Thereby providing a floor mats which can be adhered firmly through the process, and are environmentally friendly and low in manufacturing cost.

The printing layer 22 is formed on the upper surface of the film layer 21 and serves to provide a floor mat having various colors and patterns, Any material can be used as long as it can be applied to the substrate 21.

The coating layer 23 is formed on the upper surface of the printing layer 22 and is made of polyurethane having a thickness of 3 to 7 micrometers. The coating layer 23 having the thickness described above is formed on the printing layer 22 And provides a mat which is made of polyurethane and does not cause skin troubles as well as improving the appearance quality of a floor polyurethane coating mat having excellent impact resistance and sound insulation according to the present invention.

If the thickness of the coating layer 23 is less than 3 micrometers, the protective effect of the printing layer 22 is deteriorated. If the thickness of the coating layer 23 exceeds 7 micrometers, the transparency of the coating layer 23 is lowered The quality of various patterns and logos formed on the print layer 22 may be degraded.

At this time, the polyurethane constituting the coating layer 23 is preferably a transparent polyurethane which does not contain a pigment, a masterbatch or the like so as not to deteriorate the quality of various patterns and logos formed on the printing layer 22 Do.

The surface layer 20 may include a transfer layer 22-1 and a coating layer 23-1 formed on the upper surface of the transfer layer 22-1. The transfer layer 22- 1 is formed through transfer at a specific temperature and pressure at a high temperature. The transfer printing layer 22-1 formed on the surface of the fourth buffer layer 14 through transfer has excellent adhesion with the fourth buffer layer 14 And serves to provide a pattern or logo that does not permeate the fourth buffer layer 14 and is excellent in quality even though it is formed on the upper surface of the fourth buffer layer 14 made of foam, The thickness and the role of the coating layer 23 described above are the same as those of the coating layer 23, so the content thereof will be omitted.

The bottom layer 30 is formed on the lower surface of the buffer layer 20 to have a thickness of 2 to 4 millimeters. The bottom layer 30 is formed by coating a polyethylene film on one surface of a low density polyethylene having a foaming magnification of 25 to 30 times and forming an emboss.

More specifically, the bottom layer 30 is formed by laminating a polyethylene film having a thickness of 0.03 to 0.05 mm on one side of low-density polyethylene having an expansion ratio of 25 to 30 times to produce a laminate, and a polyethylene film is laminated on both sides of the laminate It is preferable that emboss is formed on the surface to be formed.

The bottom layer 30 having the above structure ultimately absorbs the impact transmitted from the buffer layer 20 to the bottom of the building, and the polyethylene film having excellent abrasion resistance is stacked on the outermost side, Since the floor layer 30 is formed on the outermost side of the floor 30 in contact with the building and is in close contact with the bottom surface of the building, it is possible to prevent the floor mat from slipping from the floor surface of the building .

If the expansion ratio of the low-density polyethylene constituting the bottom layer 30 is less than 25 times, the impact absorbing effect is insignificant. If the expansion ratio of the low-density polyethylene constituting the bottom layer exceeds 30 times, Can be lowered.

Hereinafter, the method and properties of the polyurethane coating mat for floor having excellent impact resistance and sound insulation according to the present invention will be described with reference to examples.
