Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor material, more specifically, a plastic floor material that replaces a fiber tile carpet.

[0002]

[Prior art]

 Conventionally, there are two types of flooring materials, a fiber flooring material and a plastic flooring material. Of these, a typical example of the fiber flooring material is a fiber tile carpet. This fiber tile carpet has a sheet-shaped material, which is a thread-like fiber such as nylon thread or polypropylene thread, sewn on a base material with a tufting machine in a loop shape as a surface layer. Such fiber tile carpets are soft and warm, and are widely used in offices as floor materials that are kind to people. On the other hand, a typical example of a plastic floor material is a hard tile made of vinyl chloride resin. This vinyl chloride tile is sold as a substitute for the above-mentioned conventional fiber tile carpet, although it is available in a small amount. The thickness is 4.5 to 5.5 mm, and the size is the same as that of the fiber tile carpet. It is 50 cm square.

[0003]

[Problems to be solved by the device]

 However, the former fiber tile carpet has the following problems. It is unsanitary because soil, sand, dust, etc. tend to accumulate because it is often stepped on by the feet. It is difficult to remove dirt from muddy water on your shoes when it rains and when you accidentally spill coffee. If it is used in a computer room, etc., even if it has been subjected to antistatic processing, it is easy for dust to accumulate and cause an accident. On the other hand, the latter vinyl chloride tile has the above problems. It has a cool texture and luster peculiar to plastic, and lacks suitability for indoor flooring. There is too much discomfort when laid with fibrous tile carpet. The checkered effect cannot be expressed when checkered with the same color. Due to these challenges, vinyl chloride tiles cannot be a substitute for traditional tile carpets and are only sold in small quantities. The present invention has been made with the object of solving the above problems, and while having the excellent function of a plastic floor material, it has a human-friendly texture similar to that of a conventional fiber tile carpet. The purpose is to provide a new type of flooring having.

[0004]

[Means for Solving the Problems]

 In order to solve such a problem, the flooring material of the present invention has an embossing process similar to the surface of a conventional fiber tile carpet on the surface of a transparent plastic sheet. And a special non-woven fabric mixed with multicolored colored fibers is laminated as the decorative layer of the surface layer.

[0005]

[Action]

 (1) According to the present invention described above, a plastic sheet having a tile carpet-like uneven embossed pattern on its surface is used. Therefore, unlike conventional fiber flooring materials, wipe or wash away dirt, dust, mud dirt on shoes when it is raining, dirt when spilling coffee, etc. Is possible and extremely clean. Also, if the surface layer is antistatic processed, it will not collect dust when used in a computer room. (2) According to the present invention, a special non-woven fabric in which fibers colored in various colors are mixed is laminated on the decorative layer on the surface. Therefore, since the viewer feels the fibers are soft through the transparent plastic sheet, the cold texture and gloss, which were the problems of conventional plastic flooring, are eliminated, and the texture is soft and warm. In addition, the surface of the transparent plastic sheet is embossed with a mold similar to the surface of conventional fiber tile carpets. For this reason, the appearance is almost the same as the conventional tile carpet, and even if it is laid in parallel, there is no feeling of strangeness. (3) Furthermore, when the above-mentioned embossing is made into a type having the same directionality as the tufting carpet, a checkerboard effect is applied to tiles of the same color, and the effect of the checkered pattern is clearly expressed. This makes it possible to eliminate the drawbacks of one-sided construction of plastic tiles.

【Example】

 Hereinafter, the present invention will be described in detail by way of embodiments with reference to the accompanying drawings. FIG. 1 (A) is a sectional view showing an embodiment before embossing of the surface layer constituting the flooring material according to the present invention. FIG. 1 (B) is a cross-sectional view showing an embodiment after embossing the surface layer shown in FIG. 1 (A). FIG. 2 is a sectional view showing an embodiment of the flooring material according to the present invention. FIG. 3 is a view showing a pattern on the surface after cutting the floor material shown in FIG.

In this embodiment, a vinyl chloride sheet is used as a plastic sheet, a wet non-woven cloth is used as a fiber sheet, and a floor material is prepared as follows. (1) First, 30% by weight of 5 colors of pre-colored acrylic fiber 1.5 denier x 8 mm (black, blue, beige, wine red, lavender), vinyl chloride thermal fusion fiber Is mixed at 60 w%, pulp at 5 w%, and PVA at 5 w% to prepare a wet non-woven fabric B having a basis weight of 50 g / m ² .

Next, as shown in FIG. 1A, this non-woven fabric B is formed into a so-called sandwich structure as follows. That is, a transparent vinyl chloride sheet A having a thickness of 0.3 mm is provided on the upper layer of the wet unwoven cloth B, and a white vinyl chloride sheet C having a thickness of 0.1 mm is provided on the lower layer of the wet unwoven cloth. Are laminated and thermocompression-bonded under the condition of 140 ° C. to form a surface layer D.

(2) Second, as shown in FIG. 1 (B), the surface layer D (FIG. 1 (A)) is formed on an embossing roll (not shown) previously formed in a tufting carpet-shaped mold. ), The surface layer D is embossed under the condition of 150 ° C. to form the surface layer E. When the embossing roll used in this case is produced, as shown in FIG. 3, it is preferable to produce a concavo-convex shape of a tufting carpet having a directivity only in the longitudinal direction I.

(3) Third, a backing material G having a thickness of 4.5 mm is first prepared by calender extrusion with a composition of 280 parts of an inorganic filler such as calcium carbonate, 80 parts of vinyl chloride resin, and 60 parts of a plasticizer. To create. Next, as shown in FIG. 2, the backer material G is used as a lower layer, the glass fiber sheet F for dimensional stability is used as an intermediate layer, and the surface layer E after embossing is used as an upper layer, and these are laminated. Then, the backer material G and the back surface of the surface layer E are pressure-bonded and laminated while heating to produce the floor material H illustrated.

(4) Fourth, as shown in FIG. 3, the floor material H thus created is cut into 50 cm squares to form a floor material J.

【The invention's effect】

 As described above, according to the present invention, a surface layer including a transparent plastic sheet having a tufted carpet-like embossed embossed pattern formed on the surface thereof is formed, and a colored fiber is mixed as a decorative layer of the surface layer. A technical measure was taken: flooring, which is characterized by the use of sheets. According to this structure, since the flooring material according to the present invention is a plastic tile, it can be easily washed even if it becomes dirty, and it is clean without accumulating sand, dust, etc. Even if it is used in a computer room, it has the technical effect of not having to worry about dust generation. In addition, a fiber sheet with colored fibers mixed in the surface layer is used, and an embossed pattern similar to that of tufting carpet is laid on a transparent plastic sheet on the fiber sheet. It has the same appearance and texture as the carpet, and has the technical effect of being a soft and warm floor material that is kind to people.

Further, the checkered pattern applied with the same color has a good expression of the checkered effect, and even when it is laid with a conventional fiber tile carpet, a good result with no discomfort is obtained. It was
