DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile mat to be laid on a floor and a non-slip sheet for a tile mat to be attached to the tile mat.

[0002]

2. Description of the Related Art
Mats or tile mats may be laid on floors in corridors, kitchens, washrooms, toilets, etc. for the purpose of soundproofing, heat insulation, decoration, non-slip, and the like. The tile mat is a tile mat having a small area, for example, a plurality of square mats. Therefore, there is an advantage that it is more convenient to carry than a single mat, and that the degree of freedom such as a change in the surface pattern is increased by changing the laying direction and combination. Also, it can easily cope with the area and shape of the floor surface to be laid.

If the coefficient of friction on the back surface of the tile mat is small, it is very slippery and dangerous. So, in order to increase the coefficient of friction, the back of the tile mat with tackiness,
Those in which synthetic rubber is adhered on the whole surface or in a lattice shape on the back surface are commercially available. However, even if the static friction force of the synthetic rubber against the floor surface is used, the anti-slip effect on a very smooth floor is not sufficient. In addition, in the case of conventional tile mats provided with adhesiveness, the adhesion and static friction force are attenuated from the tile mat due to repeated attachment and detachment, and the anti-slip effect is often reduced, or the anti-slip effect is reduced with time. Was.

The present invention has been made in view of the above circumstances, and provides a tile mat and a non-slip sheet for tile mats having a good non-slip effect on a floor surface by providing a non-slip layer having a vacuum attraction force. The purpose is to provide.

[0007]

The adhesion mechanism of the tile mat according to the present invention to the floor surface is based on the vacuum suction force of a large number of pores formed in the non-slip layer provided on one side thereof. That is, when the anti-slip layer is brought into contact with the floor surface and lightly pressed, the air in the pores is exhausted to be in a reduced pressure state, whereby good adhesiveness is obtained, and thus a good anti-slip effect is obtained. On the other hand, it has good peelability and can be removed many times. It is also excellent in water resistance, and the adhesion of the anti-slip layer is hardly reduced due to the presence of a little moisture.

[Table 1]

A method for manufacturing the tile mat 1 according to the present invention will be described. First, the compositions shown in Table 1 are blended and foamed by a mixer. Next, the foamed composition is applied to one surface of the tile mat body 2 by a coating device. Then, it is put into a dryer and dried at 120-160 ° C. for 5 minutes.

The anti-slip layer 3 obtained by the above-mentioned manufacturing method
The mechanism of adhesion to the floor is due to the vacuum attraction force of the numerous pores formed here. That is, when the anti-slip layer 3 is placed on the floor surface and is slightly suppressed, the air in the pores is exhausted, and the air pressure is reduced, thereby adhering to the floor. Also, even if there is a little moisture on the floor,
Adhesion is hardly attenuated unlike the adhesive layer.

Next, physical properties of the anti-slip layer 3 will be described.
Table 2 shows the results of a physical property test performed by changing the expansion ratio and the coating thickness of the anti-slip layer 3. From Table 2, it can be seen that when the expansion ratio is small, the releasability is good, when the expansion ratio is large, the adhesiveness is good, and when the coating thickness is increased, all are improved. The expansion ratio and the coating thickness may be determined in consideration of the required performance balance based on the results in Table 2.

[0015]

[Table 2]

The method of measuring the results shown in Table 2 is specifically as follows. Delamination strength: Sample preparation Adhesive to cotton cloth (F-520 thickener)
Is applied, bonded to the foam surface, heat treated and cut into 2cm width. The foam breaking strength is measured by an autograph. Cellophane tape peel strength: Cellophane tape on foam surface
(1.8mm) is firmly pasted by hand and immediately peeled off at right angles to check for damage. ○: No abnormality ×: Damage Surface friction strength: The number of times until the foam surface was rubbed with a Gakushin type friction tester (500 g flat) was read. Adhesive strength: One day after the foam sheet is pressed 2 cm wide on a glass plate, 90 ° peel strength is measured.

Next, another embodiment of the composition of the anti-slip layer 3 is shown in Table 3. The products used as the compositions in Table 3 are the same as those in Table 1.

[0018]

[Table 3]

When forming the non-slip layer 3 composed of the composition shown in Table 3, the composition shown in Table 3 is first blended and foamed 3.3 times with a mixer. Next, the foamed composition is formed into a desired sheet shape by a coating apparatus.
Then put this in a dryer for 5 minutes at 120 ° C and 2 minutes at 140 ° C.
Let dry for minutes. Also in this case, as in the above-described example, good adhesion to the floor by vacuum suction was obtained.

FIG. 3 is a rear perspective view showing a state in which the non-slip sheet for tile mat according to the present invention is attached to a commercially available tile mat, and FIG. 4 is an enlarged sectional view showing the non-slip sheet for tile mat. . Non-slip sheets 4 for tile mats are attached to four corners on the back surface of the tile mat body 2. The non-slip sheet 4 for a tile mat has a non-slip layer 3 similar to that of the above-described embodiment formed on one surface, and an adhesive layer 5 having adhesive strength formed on the other surface. As in the previous embodiment, the anti-slip layer 3 is provided with stripe-shaped grooves in order to improve the releasability.

The composition of the adhesive layer 5 is as follows: EV-40LX of Mitsui Dupont as ethylene vinyl acetate (EVA) and XSON of Exxon as ethylene methyl acrylate (EMA).
-5508, and the weight ratio between EVA and EMA was 7: 3.

A method of manufacturing the non-slip sheet 4 for a tile mat according to the present invention will be described. First, the composition of the anti-slip layer 3 shown in Table 1 is blended and foamed by a mixer. Next, the foamed composition is applied to one surface of the nonwoven fabric 6 by a coating device. Then, it is put into a dryer and dried at 120-160 ° C. for 5 minutes. Next, the composition of the pressure-sensitive adhesive layer 5 is mixed and applied to the other surface of the nonwoven fabric 6 with a thickness of 200 μm using an extruder having a diameter of 90 mm to produce a non-slip sheet 4 for a tile mat.

Anti-slip layer 3 obtained by the above-described manufacturing method
The adhesion mechanism to the floor is the same as in the previous embodiment.
This is due to the vacuum suction force of the many pores formed here. That is, if the anti-slip layer 3 is placed on the installation surface and is slightly suppressed, the air in the pores is exhausted and a reduced pressure state is established, thereby adhering to the floor. The adhesive layer 5 has an adhesive force on the surface, and can be adhered to the tile mat body 2 by the adhesive force.

The non-slip sheet 4 for a tile mat according to the present invention may have an elongated shape, for example, attached to two opposing sides, in addition to the configuration of being applied to the four corners as described above. It is easy to freely cut and change the shape of the non-slip sheet 4 for tile mats, and thus the position, shape, and number of the sheets to be stuck may be appropriately selected. Such a non-slip sheet 4 for tile mats is practical if sold in sets of several sheets. At this time, detachable paper such as release paper is attached to the adhesive layer 5. In addition, the non-slip sheet 4 for the tile mat is similarly attached with detachable paper such as release paper,
If a product longer than the size actually used is rolled and marketed, for example, it can be cut into a length suitable for the tile mat body to be attached by the user and used, which is practical.

The composition of the adhesive layer 5 is not limited to the above. For example, as another embodiment, the main component is an acrylate copolymer resin, and the solvent is toluene.
Adhesive tape "8020" (manufactured by Nippon Synthetic Chemical Co., Ltd.), which is ethyl acetate and has a resin content of 40% and a viscosity of 7000 cps / 25.degree.
The adhesive layer 5 may be attached to the other side of the sheet. Note that the tile mat body 2 is not limited to urethane.
