Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Living room,
Mats or tile mats may be laid on the floors of corridors, kitchens, washrooms, toilets, etc. for the purpose of soundproofing, heat retention, decoration, and slip prevention. The tile mat has a plurality of small areas, for example, square ones. Therefore, it has an advantage that it is more convenient to carry than a single mat, and the degree of freedom such as the change of the surface pattern is large by changing the direction and combination of the mats. In addition, the area and shape of the floor surface to be spread can be easily accommodated.

If the back surface of the tile mat has a small coefficient of friction, it is very slippery and dangerous. Therefore, in order to increase the coefficient of friction, the back surface of the tile mat is made tacky,
Commercially available products are those in which synthetic rubber is adhered on the entire surface or in a lattice pattern on the back surface. However, even if the static friction force of the synthetic rubber on the floor surface is used, the anti-slip effect on a very smooth floor is not sufficient. In addition, with conventional tile mats that have been made tacky, the adhesiveness and static frictional force of the tile mat are attenuated due to repeated attachment and detachment, and the anti-slip effect often declines, or the anti-slip effect diminishes over time. It 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 mat having a good anti-slip effect on a floor surface by providing an anti-slip layer having a vacuum suction force. The purpose is to provide.

[0005]

The tile mat according to the present invention is characterized in that the tile mat laid on the floor is provided with a non-slip layer made of synthetic resin and having a vacuum suction force on one surface side.

A non-slip sheet for a tile mat according to the present invention is a non-slip sheet to be attached to a tile mat laid on a floor surface, which has a non-slip layer made of a synthetic resin and having a vacuum adsorption force on one surface side and the other surface side. And an adhesive layer made of synthetic resin and having an adhesive force.

[0007]

The function of adhering the tile mat according to the present invention to the floor surface is based on the vacuum suction force by the large number of pores formed in the non-slip layer provided on the one surface side. 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 and a reduced pressure state is obtained, whereby good adhesiveness is obtained, and thus a good anti-slip effect is obtained. On the other hand, it has a good peeling property and can be attached and removed many times. It also has excellent water resistance, and the adhesiveness of the anti-slip layer is less likely to deteriorate due to the presence of a little water.

In the non-slip sheet for tile mats according to the present invention, the adhesive layer formed on the opposite side of the anti-slip layer has an adhesive force and can be adhered to the back surface of various tile mat main bodies.

[Table 1]

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

Anti-slip layer 3 obtained by the above-mentioned manufacturing method
The adhesion mechanism to the floor is due to the vacuum adsorption force due to the large number of pores formed here. That is, when the anti-slip layer 3 is placed on the floor surface and held down for a while, the air in the pores is exhausted to bring about a depressurized state, thereby adhering to the floor. Even if there is a little moisture on the floor surface,
The adhesiveness is unlikely to be reduced like the adhesive layer.

Next, the physical properties of the anti-slip layer 3 will be described.
Table 2 shows the results of physical property tests performed by changing the foaming 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, both are improved. The expansion ratio and the coating thickness may be determined from the results shown in Table 2 in consideration of the required balance of performance.

[0015]

-5508, and the weight ratio of EVA and EMA was set to 7: 3.

A method of manufacturing the non-slip sheet 4 for 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, this foamed composition is applied to one surface of the nonwoven fabric 6 by a coating device. Then, this is put into a dryer and dried at 120 to 160 ° C. for 5 minutes. Next, the above composition of the adhesive layer 5 is mixed and applied to the other surface of the non-woven fabric 6 with a film thickness of 200 μm by an extruder having a diameter of 90 mm to produce a non-slip sheet 4 for tile mat.

Anti-slip layer 3 obtained by the above-mentioned manufacturing method
The adhesion mechanism to the floor is similar to that of the above-mentioned embodiment.
This is due to the vacuum suction force due to the large number of pores formed here. That is, when the anti-slip layer 3 is placed on the installation surface and held down a little, the air in the pores is exhausted to a depressurized state, thereby adhering to the floor. Further, the adhesive layer 5 has an adhesive force on the surface, and can be adhered to the tile mat main body 2 by this adhesive force.

Further, the non-slip sheet 4 for tile mat according to the present invention may be adhered to the four corners as described above, or may be elongated and adhered to, for example, two opposite sides. Since it is easy to freely cut the tile mat non-slip sheet 4 to change its shape, the position, shape, and number of sheets to be stuck may be appropriately selected. Such a tile mat non-slip sheet 4 is practical if it is marketed as a set of several sheets. At this time, removable paper such as release paper is attached to the adhesive layer 5. In addition, the non-slip sheet 4 for tile mat is similarly attached with removable paper such as release paper,
For example, if a product longer than the size actually used is rolled and put on the market, it can be cut into a length suitable for the tile mat body to be attached by the user before use, which is practical.

The composition of the adhesive layer 5 is not limited to the above. For example, in another embodiment, the main component is an acrylic ester copolymer resin and the solvent is toluene.
Adhesive tape "8020" (manufactured by Nippon Synthetic Chemical Industry Co., Ltd.), which is ethyl acetate and has a resin content of 40% and a viscosity of 7,000 cps / 25 ° C, is used as a nonwoven fabric 6
The adhesive layer 5 may be attached to the other surface side. The tile mat body 2 is not limited to urethane.
