Description

  The present invention relates to a lightweight tile tile carpet that can be constructed without shifting by simply placing it on the floor without applying an adhesive to the floor surface during construction.

  The conventional tile carpet construction method is to apply an adhesive on the floor surface and apply it to the floor surface, and then apply a sticky adhesive resin to the underside of the tile carpet backing layer to adhere to the floor surface. There is a known method that can be applied without applying an adhesive, but when the tile carpet is peeled off by renewal etc., the adhesive remains adhered to the floor, and a great deal of effort is required to remove this adhesive. It was. Further, a tile carpet that can be easily replaced as a household tile carpet is desired, and the conventional method has not been used for home use because the adhesive stains tatami mats and flooring.

  Patent Document 1 discloses a tile mat provided with a non-slip layer having a vacuum adsorbing force with a large number of pores, and can be used while being peeled many times. Although it is an effective method, if the anti-slip layer is not thickened to some extent, the vacuum adsorption force becomes weak, and the weight is heavy and the cost is not satisfactory.

In Patent Document 2, the carpet can be easily connected and constructed, and is provided with a non-slip tool having a hook-and-loop fastener on the top surface of the carpet's anti-slip sheet. Although it is disclosed as a tile carpet construction method that can improve the anti-slip function, since the joint point is the end of the carpet, the joint force of the entire carpet is weak, and it is not satisfactory because it slips and peels off during use. .

  As a method for constructing a tile carpet, a lightweight tile tile carpet is provided that can be easily laid on the floor surface and can be peeled off and re-applied many times without slipping.

  In view of the above-mentioned circumstances, the present invention provides an anti-slip effect and an adhesive strength by sticking a resin having an adsorptive property and an anti-slip effect to the entire back surface of the tile carpet in a bowl shape at a certain interval. In addition, the present inventors have found that the weight can be reduced and have reached the present invention.

  That is, the tile carpet according to the first invention is composed of an anti-slip resin layer, a backing layer, a backing resin layer, and a skin layer made of pile fibers and a base fabric, and the anti-slip resin layer on the entire carpet back surface. Is a tile carpet characterized by being formed in a bowl shape.

  In the tile carpet according to the second invention, a non-slip resin layer having a large number of micro-dents on the surface of the anti-slip resin layer and micro-cavities in the micro-cavities and having a vacuum adsorption force is formed. The tiled cuppet according to claim 1, wherein

  In the tile carpet according to the third aspect of the present invention, in the non-slip resin layer, the height of the ridge is 0.5 to 3.0 mm, the width of the ridge is 2.0 to 8.0 mm, and the interval between the ridges is 5.0. The gist is the tile carpet according to claim 1, wherein a non-slip resin layer is formed to ˜50.0 mm. If the height of the ridge is higher than 3.0 mm, irregularities appear on the carpet surface, which is not preferable. When it is lower than 0.5 mm, the anti-slip effect is reduced and the effect of making it into a bowl shape is not observed. More preferably, the thickness is 1.0 to 2.0 mm. On the other hand, if the width of the ridge is wider than 8.0 mm, it is not preferable because it becomes planar and the amount of resin applied increases. If it is narrower than 2.0 mm, the anti-slip effect and the adsorption effect are reduced. If the distance between the ridges is larger than 50.0 mm, the area that comes into strong contact with the floor is small and the anti-slip effect and the adsorption effect are reduced. If the distance between the ridges is narrower than 5.0 mm, the carpet weight increases. More preferably, 10-30 mm is good. In the anti-slip resin layer, the resin thickness of the valley portion is not particularly limited, but it may be thinly applied to about 0.01 to 0.2 mm so that a ridge portion can be formed.

4. The tile carpet according to claim 1, wherein the anti-slip resin is coated with 80 to 160 g / m ² to form an anti-slip resin layer. . If the anti-slip resin is applied below 80 g / m ² , a sufficient anti-slip effect and adsorption effect cannot be obtained. On the other hand, if the coating amount exceeds 160 g / m ² , the purpose cannot be achieved in terms of weight reduction and cost.

  The tile carpet according to a fifth aspect of the present invention is characterized in that the anti-slip resin layer is formed by applying and drying a foam obtained by foaming an emulsion having an acrylic polymer, and then drying. The tile carpet according to claim 1.

Carpet tiles according to the sixth aspect of the present invention, the tile carpet weight is tile carpet of claims 1 to 5, wherein the a 1600~2000g / ^{m 2.} More preferably, it is 1600 to 1800 g / m ² .

  In the present invention, reverse warping means that when one side of a tile carpet is picked up and the carpet is hung downward, it slightly warps on the pile side of the carpet. Slight warping is preferable in construction.

  In the first invention, since the resin having the adsorptive property and the anti-slip effect is adhered to the entire back surface of the tile carpet, the entire carpet has an adsorbing effect between the floor surface and a strong adsorbing strength. It becomes. In addition, since the anti-slip resin layer is stuck in a bowl shape, the surface area of the anti-slip resin layer is increased, and it is possible to cope with minute irregularities on the floor, and a stronger anti-slip effect and adsorption strength can be obtained.

  In the second invention, since the surface of the anti-slip resin layer has a large number of minute recesses and minute voids in the minute recess, a vacuum adsorption force is developed, and the tile carpet is simply placed and pressed lightly. In close contact with the floor, anti-slip effect and adsorption strength are developed.

  In the third aspect of the invention, in the anti-slip resin layer, the height of the ridge is 0.5 to 3.0 mm and the width of the ridge is 2.0 to 8.0 mm. Correspondingly, a stable anti-slip effect and adsorption strength can be obtained. Further, when the distance between the ridges is set to 5.0 to 50.0 mm, a greater anti-slip effect and light weight can be achieved.

In the fourth invention, since the non-slip resin is applied in an amount of 80 to 160 g / m ² , a large anti-slip effect and a light weight can be achieved with a small amount of resin, and an inexpensive tile carpet can be obtained. .

  In the fifth aspect of the invention, since the anti-slip resin layer is coated with a foam obtained by foaming an emulsion having an acrylic polymer and dried, it has excellent adhesion and adsorbability and can be easily attached and detached. A non-slip resin layer that does not leave marks or the like is formed.

In the sixth invention, since the weight of the tile carpet is 1600 to 2000 g / m ² , the weight is 1/3 or less of the weight of the conventional tile carpet, and it is easy to store and transport and easy to handle. .

  The tile carpet of the present invention will be described in detail with reference to the drawings. FIG. 1 is a sectional view showing an embodiment of the tile carpet of the present invention. In the figure, a tile carpet 1 has a structure in which a carpet skin layer 4 made of pile fibers 2 and a base fabric 3, a backing resin layer 5, a backing layer 6, and an anti-slip resin layer 7 are laminated. In the present invention, the height 8 of the ridge is from the surface of the backing layer 6 to the tip of the ridge, the width 9 of the ridge is the width of the higher portion of the non-slip resin layer 7, and the interval 10 These respectively show from the end of the higher portion of the non-slip resin layer 7 to the end of the next higher portion.

  The carpet skin layer 4 is formed by planting pile fibers 2 on a base fabric 3. Although it does not specifically limit as the base fabric 3, A polyester spunbond base fabric is preferable and common. The pile fiber 2 is not particularly limited, and is composed of synthetic fibers such as polyester fibers, polyamide fibers, polypropylene fibers, and acrylic fibers, or fibers such as natural fibers such as hemp, cotton, and wool.

  The backing resin layer 5 is for fixing the pile fiber 2 and the base fabric 3 and is not particularly limited. However, the resin composition includes polyacrylate, vinyl acetate / ethylene copolymer, polyvinyl chloride, styrene Butadiene copolymer, polychloroprene, acrylonitrile-butadiene copolymer, methyl methacrylate-butadiene copolymer, polyurethane, etc. are used, and calcium carbonate, aluminum hydroxide, magnesium hydroxide, barium hydroxide, basic as filler Zinc carbonate, silica sand, etc. are used, and a resin composition containing a foaming agent, a crosslinking agent, a thickener, etc. is used.

In the tile carpet of the present invention, it is recommended that one or more glass fiber cloths or polyester fiber cloths are interposed as a reinforcing layer in order to stabilize the dimensions. As the glass fiber cloth, having a basis weight 30 to 50 g / ^{m 2} approximately nonwoven, and basis weight 25 to 45 g / ^{m 2} approximately woven and set fabrics are preferred. The reinforcing layer is disposed on the backing resin layer 5 and is impregnated with the resin to be integrated.

  Nonwoven fabric is often used as the backing layer 6. Examples of the constituent fiber include, but are not particularly limited to, synthetic fibers such as polyester fibers, nylon fibers, polyolefin fibers, and the like, or natural fibers such as wool and cotton, which are single or mixed. Examples of the type of nonwoven fabric include spunbond nonwoven fabric, chemical bond nonwoven fabric, needle punched nonwoven fabric, etc., but considering dimensional stability, a spunbond nonwoven fabric is suitable.

  In the case of the present invention, it is easier to process the non-woven fabric using the non-slip resin layer 7 previously applied in another process. A commercially available product can be used as it is as the emulsion having an acrylic polymer of the non-slip resin layer 7. As such an emulsion, trade names “Dick Form F601”, “Dick Form MF509” (Dainippon Ink & Chemicals, Inc.) and the like can be used. Add foaming aid and cross-linking agent to emulsion and foam 2-6 times with Oaks mixer etc. and apply evenly on the nonwoven fabric, and then cut the notched plate so that the foamed resin becomes wrinkled Then, while winding the non-woven fabric at a constant speed, it is dried at 100 to 150 ° C. for about 5 minutes to integrate the cocoon-shaped anti-slip resin layer into the non-woven fabric.

  In the present invention, a foamed resin layer or a thick non-woven fabric may be laminated as the backing layer 6 in order to impart cushioning properties to the tile carpet. Moreover, a nonwoven fabric or a woven / knitted fabric can also be used as the carpet skin layer.

  Next, FIG. 2 is a schematic view showing one embodiment of a process for producing a tile carpet of the present invention. First, a backing resin layer 5 is applied to the carpet skin layer 4, and then a backing layer 6 made of a non-woven fabric on which an anti-slip resin layer 7 formed in a separate process is formed is pasted. Next, after passing through a drying process, it is cooled and cut to a specified size to obtain a tile carpet.
