BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stair mat to be laid on stairs.

[0002]

2. Description of the Related Art Various stair mats have been proposed and put into practical use for the purpose of preventing slipping or muffling when going up and down stairs. As the material,
Various materials such as synthetic rubber, polypropylene, woven cloth, and non-woven cloth are adopted, and various shapes such as those laid only on corners and those laid on the entire floor surface are also used. Adhesion, friction, and the like are also used for the bonding method. For example, in the case of using synthetic rubber, the anti-slip effect is obtained by utilizing the static frictional force of the synthetic rubber on the floor surface, but the anti-slip effect often declines over time, and the sound deadening effect is not very good. Absent.

[0003] There is a type using a cushion material mat for the purpose of obtaining a noise reduction effect. In this case, an adhesive surface is formed on the back surface in order to obtain an anti-slip effect. The stair mat using such a cushion material has a problem that the adhesiveness of the adhesive surface is easily deteriorated by washing.
Moreover, the adhesiveness often deteriorated even after repeated attachment and detachment. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a stair mat having a good anti-slip effect, a sound deadening effect, and washing resistance by forming an anti-slip layer having a vacuum suction force. And

[0004]

Stairs mat according to the present invention SUMMARY OF THE INVENTION may, Te stair mat odor comprising a non-slip layer on one side of the stairs mat body made of fabric or synthetic resin sheet, multi
Made of synthetic resin with porous elasticity and has a vacuum suction force
In addition, the bottom surface is provided with a non- slip layer having a groove for adjusting the adhesive force .

[0005]

[Operation] The stair mat according to the present invention has a sliding surface formed on the back surface.
Ri so stop layer has a good adhesion by the vacuum suction force, only with good slip effect placing stairs obtained.
Also, since a groove for adjusting the adhesive force is appropriately provided,
It has good peelability, can be easily removed, and has good adhesive strength.
The area is divided by grooves so that it can be repeatedly stepped on and slipped
The deformation of the stop layer and the restoring force due to its elasticity are repeated
Also, the deformation of one area of action lifts the other area of action from the floor, etc.
Interference such as raising it is blocked and the entire mat is not positioned.
This is less likely to occur, and since the anti-slip layer has a structure with a large number of bubbles, it is possible to absorb vibration not only in the stair mat body but also in the anti-slip layer, further improving the sound deadening effect .
It

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing an embodiment thereof. FIG. 1 is a schematic view of a stair mat according to the present invention, FIG. 1 (a) is a perspective view showing a state of being mounted on stairs, and FIG. 1 (b) is an enlarged sectional view of the stair mat.
In the figure, 1 is a staircase mat body made of circular knit pile fabric, and this staircase mat body 1 is a substantially rectangular shape corresponding to the staircase shape, and its corners are rounded. On the back surface of the staircase mat body 1, there is formed a non-slip layer 2 formed by applying a mixture having the composition described later.

The composition of the anti-slip layer 2 in the present invention is as shown in Table 1. Specifically, the synthetic resin (emulsion) is a urethane type product "DICFOAM F-520", and the foaming agent is "F-1". ", 4% concentration of CMC as a surfactant
, "VONCOAT 3750" was used as the auxiliary agent (1), "CR-5L" was used as the auxiliary agent (2), "VONDIC NBA-1" was used as the auxiliary agent (3), and "CATALYST PA-20" was used as the catalyst. "CMC" is manufactured by Daiichi Kogyo Seiyaku Co., Ltd., and other products are manufactured by Dainippon Ink and Chemicals Co., Ltd.

[0008]

[Table 1]

The adhesion mechanism of the non-slip layer 2 made of such a material to the floor is the vacuum adsorption force due to the large number of pores formed therein. That is, if this is suppressed a little, the air in the pores is discharged and a reduced pressure state is created, whereby the air adheres to the floor.

When the anti-slip layer 2 is formed on the staircase mat body 1 by coating, the compositions shown in Table 1 are first mixed and foamed by a mixer. Next, this foamed composition is applied to one surface of the staircase mat body 1 by a coating device. Then, this is put into a dryer and dried at 120 to 160 ° C. for 5 minutes.

Table 2 shows the results of the physical property test of the anti-slip layer 2 when the anti-slip layer 2 was applied by changing the expansion ratio and the coating thickness. 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.

[0013]

[Table 2]

The method of measuring the results shown in Table 2 is specifically as follows. Delamination strength: Sample preparation Cotton cloth with adhesive (F-520 thickening liquid)
Is applied, laminated with the foam surface, heat treated and cut to a width of 2 cm. Measure foam breaking strength by autograph. Cellophane peel strength: Cellophane tape on the foam surface
Stick (1.8mm) firmly by hand and instantly peel it off at a right angle to check for damage. ○: No abnormalities ×: Damage Surface friction strength: Rubbing the foam surface with a Gakushin-type friction tester (Flat 500g) and reading the number of times until damage. Adhesion: A 2 cm wide foam sheet is pressure-bonded to a glass plate, and one day later, the 90-degree peel strength is measured. Even when the washing was repeated 20 times, there was no change in the adhesion of the anti-slip layer 2.

Next, Table 3 shows other examples of the composition of the anti-slip layer 2 in the present invention. The products used as the composition in Table 3 are the same as those in Table 1.

[0016]

[Table 3]

When the anti-slip layer 2 made of the composition shown in Table 3 is applied and formed on the staircase mat body 1, the composition shown in Table 3 is first mixed and foamed 3.3 times with a mixer. Next, this foamed composition is applied to one surface of the staircase mat body 1 by a coating device. Then, this is put in a dryer and dried at 120 ° C. for 5 minutes and 140 ° C. for 2 minutes.
In this case as well, as in the above-mentioned examples, good adhesion to the floor was obtained by vacuum adsorption.

Since the non-slip layer 2 is made of, for example, a urethane resin having a large number of bubbles, not only the staircase mat body 1 but also the non-slip layer 2 absorbs the vibration, and the sound deadening effect is obtained. Further improve.
