Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a fiber floor tile used as a floor covering for a house or the like.

[0002]

2. Description of the Related Art Conventionally, fiber floor tiles have advantages such as easy laying construction, easy portability, easy partial replacement, and excellent designability due to combination of colors and shapes. Up until now, it has spread to non-residential fields, but in the residential field, it is not used because of the hard backing layer and lack of habitability due to the structure of the product, and long fiber flooring has been mainly used. . However, when a long fiber flooring material is used in the living field, even if the stain or wear is partial, it is not possible to replace only that part, and it is completely replaced, which is uneconomical. Further, when replacing the furniture, all the furniture and the like arranged on the long fiber flooring had to be moved, which was very troublesome. Therefore, for the living of the fiber floor tile having the above-mentioned advantages, a resin foam or a laminate of fiber layers has been developed and used for the backing layer, but these are too important to walk and resin strength, There were problems such as weak elastic strength, peeling of the fiber surface layer due to long-term load, elastic fracture, warpage at the abutting portion due to elongation, poor dimensional stability, and elongation and contraction due to temperature.

[0003]

DISCLOSURE OF THE INVENTION The present invention solves the above problems and is excellent in stationary stability and durability required for floor coverings of houses and the like, and yet has cushioning property, walking feeling, heat retaining property and sound insulation. An object is to provide a fiber floor tile having excellent properties and the like.

[0004]

Means for Solving the Problems The above-mentioned problems are the surface of the present invention, a fiber surface layer (1) composed of a fibrous material, a polymer resin backing layer (2), and a woven or non-woven fabric made of inorganic or organic fibers. Reinforcing material backing layer (3), thickness 3m
A fibrous non-woven fabric of m or more, in which each fiber is fused and reinforced by fusible fibers, a fibrous backing layer (4) containing a fused fiber and a polymer resin backing layer (5) are sequentially laminated. Settled with fiber floor tiles. Hereinafter, the present invention will be described.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The fiber surface layer (1) of the fiber floor tile of the present invention comprises a base fabric layer (7) and a pile layer (6), which are conventionally used for tile carpets such as nylon, acrylic and polyester. , Synthetic fibers such as polypropylene or natural fibers such as wool are cut into a woven or non-woven base fabric layer of synthetic fibers such as polyester or polypropylene,
A pile layer having a loop shape or a combination of cuts and loops is used. In particular, it is sufficient if it can withstand residential use regardless of the density of the pile layer. The fiber surface layer (1) imparts designability, heat retention, sound absorption and the like to the fiber floor tile.

The polymer resin backing layers (2) and (5) of the fiber floor tile of the present invention are made of a high-grade resin such as ethylene resin, ethylene vinyl acetate resin, polyvinyl chloride resin, amorphous olefin polymer resin and asphalt resin. Although a molecular resin can be used, a vinyl chloride resin and an amorphous olefin polymer are particularly preferable in terms of performance, ease of use, cost and the like. When these resins are used for the polymeric resin backing layer (2), they have appropriate bending resistance, so the entire resin surface receives the load,
Prevents partial dents and warpage due to point load. Also,
Since it has sufficient adhesive strength, it prevents peeling of the fiber surface layer. Further, when used for the polymer backing layer (5), it is appropriately stiff and flexible, so that it can be placed on a floor base well, and can sufficiently withstand lateral displacement load caused by walking or the like.

The woven or non-woven fabric used for the reinforcing material backing layer (3) of the fiber floor tile of the present invention has the property of preventing elongation against load, elongation against temperature change and contraction. If it can be used. In particular, in the case of glass fiber woven cloth, since it can be embedded in the polymer resin backing layer (2) through the mesh, the manufacturing process can be simplified,
In addition, a reinforcing effect that is balanced vertically and horizontally can be obtained. In the case of a non-woven fabric, a basis weight of 30 g / m ² or more is preferable from the viewpoint of dimensional stability, but it is important to sufficiently impregnate the polymeric resin backing layer (2).

The fusible fiber-containing fibrous backing layer (4) of the fiber floor tile of the present invention comprises a heat-fusible fiber having a melting point of 150 to 170 ° C. in an organic fiber layer of natural, synthetic or semi-synthetic type. 20 to 50 parts by weight are uniformly mixed with 100 parts by weight of the fiber, and 20 to 5 are added to the upper surface, the lower surface or both upper and lower surfaces of this layer.
This is a non-woven fabric in which 0 parts by weight of polyester spunbonded non-woven fabric is superposed, and at the same time, a web layer is formed by a needle punching machine, and then the organic fiber layers are melt-bonded by heating. In a needle-punched non-woven fabric in which each fiber is only mechanically entangled, the inter-fiber bond is cut due to shear stress, or the inter-fiber peeling occurs due to the tensile force during replacement. In addition, when each fiber is bound with a binder such as synthetic resin latex, there is a problem that flexibility and cushioning properties are lacking and resin breakage occurs due to a load, resulting in separation between fibers. On the other hand, the fused fiber-containing fibrous backing layer (4) of the present invention has mechanical strength, flexibility and cushioning property because each fiber is bonded by fusion bonding with homogenous fibers having a low melting point. Excellent characteristics are obtained. The thickness of the fibrous lining layer (4) containing the fusion fiber is 3 mm or more and has a density of 0.05 to 0.08 g / cm in view of cushioning properties, walking feeling, sound insulation properties, etc. in the living field.
³ is suitable, but it may be other than this depending on the manufacturing method.

In the fiber floor tile of the present invention, a polymer resin backing layer (5) is coated on a Teflon coating belt with a doctor knife so as to have a thickness of 1 to 2 mm, and a nonwoven fabric layer (4) serving as a cushion layer is formed thereon. On top of it, and the polymer resin backing layer (2) on it with a doctor knife for 2-3 m
After being applied in a thickness of m, the reinforcing material backing layer (3) is laminated thereon so that the base surface layer (7) of the fiber surface layer (1) faces downward, and then laminated. The entire surface is pressed to sufficiently impregnate the base fabric layer (7) of the fiber surface layer (1) with the polymer resin backing layer (2), and then the polymer resin backing layer (2) and the polymer backing layer (5) After the solidifying process, it is cut into tiles to obtain the fiber floor tile of the present invention.
When the resin used in the polymeric resin backing layer (2) or (5) is vinyl chloride resin, the solidification processing is 180 to 22.
Heat to 0 ° C. then cool. Further, in the case of the amorphous olefin polymer composition, since it is applied in a state of being heated and melted at 180 to 200 ° C., the solidification processing treatment is only cooling.

The thus obtained fiber floor tile of the present invention comprehensively exhibits the characteristics which have not been heretofore obtained, and in particular, when the weight is applied, the entire surface does not receive a local depression, and the cushioning property and the walking feeling are obtained. Excellent performance in living environment such as heat retention and sound insulation.
