[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a floor finishing material, and more particularly to a floor finishing material having a structure in which local swelling due to vapor pressure of moisture or an organic solvent does not occur on a construction surface of the floor finishing material during bonding.
[0002]
[Prior art]
For floor finishing materials used on floors of apartment houses, various stores, offices, schools, hospitals, nursing homes and medical facilities, etc. In order to prevent this, a floor finishing material having a laminated structure of a plurality of layers and having improved absorption of floor impact sound is used.
[0003]
Such a floor finishing material basically has a surface decorative layer having a plurality of laminated structures, and a laminated structure composed of a foam layer laminated below the surface decorative layer. After applying an adhesive such as an adhesive or an aqueous latex adhesive, and taking a predetermined open time (waiting time), the adhesive is applied to the surface of the floor base material on the construction surface, or the floor finish material After applying synthetic rubber latex, aqueous emulsion, and organic solvent-based adhesive using a jig such as a comb-shaped iron on the surface of the floor base material, take a predetermined open time (waiting time), and then finish the floor. It is constructed by sticking materials.
[0004]
In this case, when the floor finishing material having a floor impact sound absorbing property is bonded, the moisture or the organic solvent of the adhesive, and the floor base material on the working surface, particularly, a concrete slab, a mortar, or an ALC board on which mortar is cast. Due to the influence of the vapor pressure due to the moisture and the like, local swelling (swelling) often occurs in the floor finishing material after bonding.
[0005]
This swelling phenomenon is particularly remarkable at the time of construction in the winter season, and occurs several days after the floor finishing material is immediately adhered, and it is necessary to remove the floor finishing material again and correct local swelling again It has extra work and labor.
[0006]
Such local swelling of the floor finishing material after the bonding work is caused by the entangled air (partially adhesive) at the time of bonding (laying) in the floor finishing material having a relatively flexible foam layer. The vapor pressure of the above-mentioned water or organic solvent is applied to a portion such as a void portion which is not bonded due to the above or a portion of the adhesive reservoir (a portion having a large amount of the adhesive), and swelling tends to occur around the portion, To prevent this, some skill was required in applying the adhesive, attaching the floor finishing material (setting an open time), and applying pressure (bleeding air) after the application.
[0007]
[Problems to be solved by the invention]
In view of the present situation, the present invention has the above-mentioned problems, that is, local swelling of the floor finishing material due to the vapor pressure due to the moisture of the adhesive or the organic solvent or the moisture of the base material at the time of bonding the finishing floor material.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, specific embodiments of the floor covering material provided by the present invention will be described with reference to the drawings.
[0013]
The basic structure of the floor finishing material provided by the present invention, particularly the floor finishing material having a floor impact sound absorbing property, is composed of a surface decorative layer and a backing layer laminated on the back surface thereof for absorbing the floor impact sound. Each of the surface decorative layer and the backing layer has a laminated structure of a plurality of layers.
[0014]
That is, FIG. 1 schematically shows a cross-sectional structure of a layer based on one embodiment of the floor finishing material provided by the present invention. In the drawing, 1 is a floor finishing material provided by the present invention. The layer structure of the flooring 2 is composed of a surface decorative layer 3 and a backing layer 4 laminated thereunder.
[0015]
In the present embodiment, the surface decorative layer 3 has, as a specific example, a layer 5 having a transparent or colored embossed print or embossed structure on its surface, and then a synthetic resin transparent layer 6, It is obtained by laminating a layer 7, a foamed or non-foamed layer 8, and a base material layer 9. In addition, whether or not to emboss the surface portion is appropriately determined according to the intended use of the floor finish material provided by the present invention.
[0016]
The surface decorative layer 3 has substantially the same layer structure as a so-called ordinary surface-decorated floor material. That is, the synthetic resin transparent layer 6 has a thickness of about 0.1 to 1.0 mm.
[0017]
In this case, a design as a floor finish is applied to the print layer 7, and the foaming layer 8 has a foaming ratio that is not so high in view of the fact that it is a foam layer constituting a part of the surface decorative layer. Not expensive. More specifically, it is sufficient to have a foaming ratio of about 1.5 to 5 times.
[0018]
The foamed layer 8 in the surface decorative layer 3 may be a non-foamed layer, and a thickness of about 0.2 to 3.0 mm is sufficient.
[0019]
The base material layer 8 of the surface decorative layer 3 is a fiber layer such as a woven fabric or a nonwoven fabric, and is particularly preferably a nonwoven fabric layer. The thickness may be about 0.1 to 1.0 mm.
[0020]
On the other hand, the backing layer 4, which is laminated on the back surface of the surface decorative layer 3 and absorbs the floor impact sound, has a layer structure composed of a foam layer 9 and a fiber layer 10, and has a floor impact sound absorbing floor. Since it is a finishing material, it is preferable that the foaming ratio of the foaming layer 9 is slightly higher than that of the foaming layer 8 in the surface decorative layer 3 and has a high foaming ratio of about 2 to 30 times. The thickness of the layer is also preferably about 1 to 10 mm.
[0021]
The fiber layer 11 to be laminated on the back surface of the foam layer 10 is a woven or non-woven fabric layer, particularly preferably a non-woven fabric layer, and may have a thickness of about 0.1 to 1.0 mm.
[0022]
The synthetic resin used for forming each layer is not particularly limited. For example, a synthetic resin used in flooring materials so far, specifically, a polyvinyl chloride (PVC) system, Acrylic, polyurethane, polypropylene, ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA), and other various thermoplastic resins can be used alone or in combination. . Further, various crosslinkable resins can be used, and such crosslinkage is not particularly limited, such as crosslinkage by a crosslinking agent, crosslinkage by heat, light or electron beam.
[0023]
Various inorganic fillers, antibacterial agents, antifungal agents and the like can be added to these resin components as desired.
[0024]
As described above, in the floor finishing material provided by the present invention, the back surface of the floor material, particularly the surface of the backing layer composed of the foam layer 10 and the fiber layer 11 constituting the backing layer 4 on the floor base material side, , Continuous grooves 20, 20... Are provided, and a wrapping air bleeding structure is provided when the floor finishing material is bonded.
[0025]
Such a continuous groove is not particularly limited with respect to a processing method for providing the groove, but is provided, for example, by embossing such as a hot press in the case of a backing layer or a nonwoven fabric alone. Since the vapor pressure of moisture or the organic solvent is released in the horizontal direction through the continuous groove provided, the size of the groove may be any size as long as it is sufficient to release the vapor pressure. It is sufficient if the width is about 0.2 to 5 mm and the height is about 0.1 to 3 mm.
[0026]
It is preferable that the continuous groove reaches the end face of the floor finishing material, so that when the floor finishing material is applied, air transmitted through the groove escapes from the end face to the outside. Furthermore, when a plurality of floor finishing materials are successively arranged, the continuous grooves of the adjacent floor finishing materials are communicated with each other at the end face. It becomes possible to discharge more.
[0027]
In addition, the processing of the embossed structure of the continuous groove may be performed, for example, on a square or rectangular floor finishing material by a single embossing in a direction parallel to the outer shape, or on a grid crossing with it. It may be embossed. Further, the processing direction of the continuous groove may be a direction in which an angle is provided with respect to the outer shape of the floor finishing material.
[0028]
In addition, the floor finishing material of the present invention is not limited to those having the above-described specific laminated structure, but is basically a continuous groove as an air release structure on the bonding construction side of the floor material. Needless to say, any material having an embossed structure may be used.
【The invention's effect】
In the floor finishing material of the present invention configured as described above, a fiber layer, in particular, a nonwoven fabric layer is bonded to the back surface side in contact with the construction base, and the embossed structure for forming a continuous groove is bonded. The moisture of the agent and / or the base material, the vapor of the organic solvent, and / or the entrained air at the time of laying can be dissipated in the horizontal direction through the voids and the continuous grooves of the nonwoven fabric. It has become possible to prevent local blisters that have occurred.
[0029]
In particular, local swelling of the floor finishing material caused by the effects of adhesive, base material, entrapped air, adhesive pool, etc., which occurred up to several days from immediately after construction until the construction adhesive coagulated and hardened In that point, the workability is remarkably improved.
