Figs. 1 to 3 are sectional views showing an embodiment of the odor-reducing fabric floor according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the structure and operation of the odor-reducing fabric floor according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 are cross-sectional views showing an embodiment of the odor-reducing fabric floor according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to Figure 1, a preferred embodiment of the present invention relates to a flooring comprising a lower layer 100, an odor barrier layer 120 and a PVC fabric layer 130.

The flooring material may be applied to a heating mat including an electric plate or a hot plate.

The lower layer 100 is the most basic layer that imparts bufferability to the flooring material, and serves to support the upper odor-blocking layer 120 and to absorb impacts of the upper and lower portions. The lower layer 100 may be formed in a form of one layer or two or more layers in the form of a foam layer or a non-foam layer.

The lower layer 100 may have a composition of 100 parts by weight of a PVC resin, 20 to 100 parts by weight of a plasticizer, 0.1 to 8 parts by weight of a heat stabilizer, and 0 to 250 parts by weight of a filler.

If the lower layer 100 is too thick, the thickness of the entire bottom layer may become thick, and heat transfer may not be efficient. Therefore, it is preferable that the bottom layer 100 has a thickness of 4 mm or less.

Since the odor generated by the compound in the liquid organic composite stabilizer is much generated in the production of polyvinyl chloride (PVC) substantially in the lower layer 100, the liquid organic compound stabilizer which does not use the smell is not used, Stabilizer can be added to prevent smell.

The Ca-Zn system is preferably a powder type, and Ba-Cd system, Ba-Zn system, Ca-Zn system, Zn stabilizer is applied rather than a stabilizer which is harmless to the human body, considering the use of a warm mat, that is, a product which is directly contacted to the human body.

In addition, the Ca-Zn system can be mixed with various resins as heat stabilizer to maintain the physical and chemical properties of the resin during processing and the finished product, and it can be harmless to the human body and suitable for flooring.

The odor barrier layer 120 is provided to block the odor coming from the lower layer 100 and is made of polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polyurethane (PU), thermoplastic polyurethane (TPU), thermoplastic olefin (TPO), acrylic, and polylactic acid (PLA).

It is preferable to select polyvinyl chloride (PVC), and the odor barrier layer 120 may include a powder type stabilizer in which an organic compound is excluded without using a liquid organic compound that causes an odor, Zn-based stabilizers may be included.

The odor barrier layer 120 may be composed of 100 parts by weight of a PVC resin, 20 to 100 parts by weight of a plasticizer, 0.1 to 8 parts by weight of a heat stabilizer, and 0 to 250 parts by weight of a filler.

If the thickness of the odor barrier layer 120 is less than 0.1 mm, the odor barrier effect may be insufficient. If the thickness of the odor barrier layer 120 is less than the thickness of the odor barrier layer 120, Is more than 3.0 mm, the thickness becomes thicker without any further odor blocking effect, which may lead to an increase in the overall manufacturing cost of the flooring.

The PVC fabric layer 130, which is provided on the upper side of the odor barrier layer 120 to reduce the smell of polyvinyl chloride (PVC), is made of PVC fabric or PVC coated fabric such as polyester or nylon, A sheet can be produced.

In order to vary the appearance of the fabric, it may be woven using two or more different colors of polyvinyl chloride (PVC), and the pattern may be formed by dyeing or printing on the fabric surface, if necessary.

The weaving method can be selectively used according to needs such as plain weave, twill weave, etc. Also, a powder type stabilizer in which an organic compound is excluded can be included to prevent odor generation, and a Ca-Zn type stabilizer can be preferably included.

It may also be desirable to use a pigment of the powder type that does not contain an organic compound in the pigment or dye to be added to impart the hue to the PVC fabric layer 130.

2, a dimension-stabilizing layer 110 may further be interposed between the lower layer 100 and the odor-blocking layer 120.

The dimensional stability layer 110 serves to complement the dimensional stability of the floor mat. In the case of the flooring, the dimension changes due to the temperature change due to heating or the like, and consequently, This is to ensure such dimensional stability.

The dimension stabilizing layer 110 may be made of glass fiber impregnated with at least one of polyvinyl chloride (PVC), acrylic resin, melamine resin and polylactic acid (PLA) resin, And may have a unit mass per unit area of 20 to 150 g / m < ² >.

If the weight of the glass fiber is less than 20 g / m ² , the effect of reinforcing the dimensional stability may be insufficient. If the weight of the glass fiber exceeds 150 g / m ² , the thickness becomes thicker without any further dimensional stability effect, ≪ / RTI >

The materials added to the dimension stabilizing layer 110 are preferably added in an amount of 30 to 150 parts by weight based on 100 parts by weight of the resin, 30 parts by weight or less of the viscosity reducing agent, and 250 parts by weight or less of calcium carbonate And 50 parts by weight or less in the case of titanium dioxide.

The dimension stabilizing layer 110 preferably has a thickness of 0.1 to 1.0 mm. When the thickness of the dimension stabilizing layer 110 is less than 0.1 mm, the dimension stabilizing effect may be insufficient, and when the thickness of the dimension stabilizing layer 110 is If it exceeds 1.0 mm, the thickness becomes thicker without any further dimensional stability effect, which may lead to an increase in the overall manufacturing cost of the flooring.

As shown in FIG. 3, the surface treatment layer 140 may further be formed on the PVC fabric layer 130.

The surface treatment layer 140 is formed on the PVC fabric layer 130 for the purpose of improving the surface quality such as scratch resistance and abrasion resistance of the bottom material and improving the stain resistance to facilitate cleaning.

The surface treatment layer 140 may include polyurethane, urethane acrylate, and the like.

The surface treatment layer 140 may be formed by various methods. In the present invention, in the case of a general PVC fabric flooring, a UV treatment agent flows into a gap between weaving structures, and ultraviolet light is not properly transmitted through the gap If the UV curing is not properly performed and consequently, the UV curing agent is not cured, the remaining un-curing agent may generate a malodor. Accordingly, the surface treatment layer 140 of the present invention is formed by applying a one-component type or two-component type treatment agent to the laminated PVC fabric layer 130 using any one selected from polyurethane or acrylic type, Heat drying or thermal curing.

The surface treatment layer 140 preferably has a minimum thickness of 8 microns and an average thickness of 15 microns. This is because when the surface treatment layer 140 is formed to a thickness of less than 8 microns, it is expected to improve the physical properties such as scratch resistance If it is more than 15 microns, it may take a lot of manufacturing cost to form the surface treatment layer 140.

The method for manufacturing the odor-reducing textile flooring according to the present invention having the above-described structure will now be described.
