Generally, the thickness is 2.0 to 3.0 m / m and the length of one side is about 30 cm. These tiles made of synthetic resin are used by being attached to the base with an adhesive. Therefore, partial repair or replacement is difficult. Further, even in the case of total re-pasting, a great deal of labor and cost are required for the peeling work and the subsequent repair of the base. Furthermore, since it adheres to the base with an adhesive, it cannot be reused after use, and effective use of resources cannot be measured, and there is a problem in terms of pollution in waste disposal.

等に優れていなければならない。A floor material made of synthetic resin is required to have various performances such as abrasion resistance, stain resistance, strength, dimensional stability, and workability. Above all, when considering the effective use of resources, refilling work, repair, application to free access floors, etc., as floor materials,
Ideally, it should have sufficient performance to be used without using an adhesive. In order to meet such requirements, in addition to general performance as tiles, curling resistance (property that does not cause warpage), dimensional stability against temperature changes, strength, load resistance, and compatibility with substrates , The workability must be excellent.

ましくは約25wt％である。Therefore, in the present invention, the surface layer is a layer containing a large amount of resin (resin amount is 25 wt% or more), and is a layer having general performance as a floor tile such as abrasion resistance, stain resistance, and breakage resistance.
The surface layer has a thickness of 0.3 to 1.5 m / m. If it is thinner than 0.3 m / m, the strength and wear resistance are insufficient, and if it is 1.5 m / m or more, the strength such as wear resistance is sufficient, but on the contrary, the strength of the surface layer is too large and warpage is likely to occur, It is not preferable because it becomes expensive in terms of cost. As the surface layer, a material obtained by heating and kneading a thermoplastic resin into a sheet, or a material obtained by once pulverizing and pressing the thermoplastic resin is used. Polyvinyl chloride is generally used as the resin. The polyvinyl chloride may be added with usual compounding agents such as plasticizers and fillers. In particular, plasticizers are important in providing the floor tile with appropriate flexibility. If the amount of the plasticizer is too small, the rigidity becomes strong and the conformability to the substrate is deteriorated, which is unsuitable for the floor tile of the present invention. On the other hand, if the amount is too large, it becomes too soft and the performance such as load bearing becomes poor. The amount of plasticizer used is usually about 15-40 wt%, preferably about 25 wt%.

は約20wt％である。A lower layer of 40 wt% or more of a filler is integrally provided on such a surface layer. This lower layer is a layer with 40% by weight or more of a filler, which is inexpensive and has a large specific gravity. It has good load resistance and dimensional stability, and has a large thickness difference from the surface layer to increase its own weight and surface layer. Prevents warpage to the side. The thickness difference from the surface layer is preferably 2 times or more, more preferably 3 times or more in order to prevent curling (curling). This lower layer also uses the same thermoplastic resin as the surface layer, and polyvinyl chloride resin is the most common. Further, this lower layer is also required to have such flexibility that it fits well with the base, and when polyvinyl chloride is used as the resin, a plasticizer is blended to exhibit such performances (compatibility and flexibility). When a large amount of a plasticizer is added, the conformability is improved, but the load resistance is reduced. Therefore, the amount of the plasticizer blended in the lower layer is usually about 10 to 30 wt%, preferably about 20 wt%.

る。In the present invention, since the floor tile is not fixed to the floor base with an adhesive, the floor tile may be displaced due to running or the like. Therefore, the floor tile of the present invention has an overall thickness of about 4 m / m or more, which is about twice the thickness of the conventional tile or more, to increase its own weight and prevent the displacement. Of course, a non-slip layer may be provided on the back surface of the floor tile of the present invention. The non-slip layer can measure the non-slip depending on the shape of the layer, or can utilize the properties of the material forming the layer. As such an anti-slip layer, there are rubber and various synthetic resin compositions, but a trimellitic acid-based plasticizer such as trioctyl trimellitate is added to polyvinyl chloride in 100 parts by weight with respect to 100 parts by weight of the resin. A composition obtained by blending the above is effective.

In this invention, such a problem is solved by dividing a reinforcing material impregnated with a foamable synthetic resin into two layers and burying the reinforcing material in a floor tile. Of course, it is known to use a reinforcing material such as glass fiber as a method of improving the dimensional stability, but the floor tile according to the present invention is thicker than the conventional floor tile and reinforced as described above. It is not enough to have only one layer, and two layers of reinforcing material improve dimensional stability and strength against load. As the reinforcing material, a material impregnated with a foamable synthetic resin is used. The amount of the foamable resin used is 50 to 500 g / m 2, preferably 100 to
It is 300 g / m 2 .

上を計ることもできた。As for the reinforcing material, it is preferable to embed the first reinforcing material in the upper side from the center of the entire thickness of the floor tile and the second reinforcing material in the lower side from the center. In the case of a laminate, warping may occur if the balance of strength between layers is lost. Therefore, the embedding position of the reinforcing material is adjusted in consideration of the overall balance. In the present invention, it is preferable to embed the upper and lower sides with the center of thickness as a boundary. As a result, warpage can be further prevented, and dimensional stability and load resistance can be improved. However, when two layers of reinforcing material are used, it is effective to balance them more easily if they are separated from each other, and it is effective in preventing warpage, but if they are too far apart, it becomes difficult to bend the floor tile with ordinary reinforcing materials, and Familiarity and workability are also reduced. The reason is that the conventional reinforcing material is used by impregnating the inside with a non-foaming synthetic resin composition, and since the reinforcing material has a dense structure, it is deformed by bending stress and This is because the property of absorbing and relaxing stress is poor and the rigidity becomes strong, and as a result, the floor material is stretched. However, in the present invention using the reinforcing material impregnated with the foamable resin, the bending stress is absorbed and relaxed by the deformation of the bubble portion inside the reinforcing material with respect to the bending stress. It was also possible to improve the compatibility with the substrate.
発泡性樹脂の発泡倍率は1.3〜3.0倍程度が好ましい。1.
3倍未満であると床タイルとしてのなじみ性が低下する

しくない。The expansion ratio of the expandable resin is preferably about 1.3 to 3.0 times. 1.
If it is less than 3 times, the conformability as a floor tile is deteriorated, and if it is more than 3.0 times, delamination or roughening occurs, which is not preferable.

に限定されるものではない。The first and second reinforcing materials may be the same or different. Examples of these reinforcing materials include non-woven fabrics, woven fabrics, nets, mats and the like using organic fibers and inorganic fibers. Among them, glass fiber non-woven fabric is preferable from the viewpoint of cost and improvement of dimensional stability. As the synthetic resin with which the reinforcing material is impregnated, the same resin as the synthetic resin forming the base or a resin having a high affinity with it is preferable. Usually, a paste mainly composed of polyvinyl chloride or a copolymer of polyvinyl chloride and another resin can be mentioned. Examples of the plasticizer include DOP and BBP, and examples of the filler include calcium carbonate, silica and mica. For the foamable resin, any method such as mechanical foaming and chemical foaming can be used. In the case of mechanical foaming, it is general that a paste containing a surfactant and the like is mechanically mixed with air, and the paste has already been foamed before being impregnated with the reinforcing material. On the other hand, in the case of chemical foaming, a so-called chemical foaming agent which decomposes and releases gas by heat such as azodicarbonamide is mixed in the paste, and the reinforcing agent is impregnated and then heated to decompose the foaming agent. This is a method of curing the paste. However, these exemplified compounds and methods are merely examples, and the present invention is not limited thereto.

用すればよい。The floor tile according to the present invention is used by simply laying it on a base without using an adhesive. The floor base is not particularly limited, such as a general corkreet floor base of a building, a floor board of a free access floor, and a heating floor panel. Further, since no adhesive is used, the floor tiles after use can be recovered and reused. In recycling, the tile after use is subjected to steps of crushing, washing, and drying, and then heat-kneaded into a sheet, which may be used as a middle layer or a lower layer of a new floor tile.

いので補強材の繊維のほぐれ、分散性も向上する。Effect of the Invention The floor tile of the present invention can be used simply by laying it without using an adhesive. Since the reinforcing material is impregnated with a foaming resin, it has excellent heat insulating properties as a floor tile and is highly compatible with the base.
Therefore, construction is easy, and replacement after construction can be done quickly. In addition, since it is highly compatible with the groundwork, there is no need to attach it to the groundwork with an adhesive, and since the floor material is not contaminated with the adhesive, the floor tiles after use can be recovered and reused, which is an effective resource It can be used and pollution problems can be prevented. In particular, when the waste tile pieces are kneaded for reuse because they are impregnated with a foaming resin, the reinforcing material with bubbles has a larger share when kneading with rolls than the reinforcing material with a dense structure impregnated with non-foaming resin. Since the cell structure is easily broken, the fibers of the reinforcing material are loosened and the dispersibility is improved.
