BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat laid on a floor made of wood, synthetic resin or tile.

[0002]

2. Description of the Related Art Mats such as kitchen mats and toilet mats are often laid on smooth floors such as wooden floors and floor carpets.
Fabric mats are very slippery and dangerous. Therefore, synthetic rubber was adhered to the back surface of the mat in the entire surface or in a grid pattern, and the anti-slip effect was obtained by utilizing the static frictional force of the synthetic rubber against the floor surface, but the anti-slip effect on a very smooth floor was not sufficient. Was. Further, in such a conventional mat, the synthetic rubber may be detached from the mat due to repetition of washing, or the anti-slip effect may be reduced. In addition, the anti-slip effect often decreased with time.

The present invention has been made in view of such circumstances, and provides a mat having a good anti-slip effect and washing resistance by forming a non-slip layer having a vacuum suction force or an adhesive force. With the goal. Another object of the present invention is to provide a mat that facilitates peeling off from the floor during washing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings showing embodiments thereof. FIG. 1 is a perspective view of the toilet mat according to the present invention, and FIG. 2 is an enlarged sectional view. In the figure, reference numeral 1 denotes a mat main body made of a pile knitted pile fabric, and has a shape in which one side of a substantially rectangular shape is recessed along the shape of the lower part of the toilet. An anti-slip layer 2 formed by applying a mixture of a composition described later is formed on the back surface of the mat body 1.

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

[0008]

[Table 1]

The mechanism of adhesion of the non-slip layer 2 to the floor by such a material is a vacuum suction force by a large number of pores formed here. That is, if this is slightly suppressed, the air in the pores is exhausted and a reduced pressure state is established, thereby adhering to the floor.

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

Table 2 shows the results of a physical property test of the anti-slip layer 2 when the anti-slip layer 2 was applied while 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, all are improved.

The expansion ratio and coating thickness may be determined in consideration of the required performance balance based on the results shown in Table 2.

[0013]

[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. Even when washing was repeated 20 times, no change was observed in the adhesion of the non-slip layer 2.

Next, another embodiment of the composition of the anti-slip layer 2 according to the first invention is shown in Table 3. The products used as the compositions in Table 3 are the same as those in Table 1.

[0016]

[Table 3]

When a non-slip layer 2 composed of the composition shown in Table 3 is applied to the mat body 1, the composition shown in Table 3 is first blended and foamed 3.3 times with a mixer. Next, the foamed composition is applied to one surface of the mat body 1 by a coating device. And put it in the dryer 12
Dry at 0 ° C for 5 minutes and at 140 ° C for 2 minutes. Also in this case, good adhesion to the bed by vacuum suction was obtained as in the above-described example.

The composition of the anti-slip layer 2 in the second invention is an ethylene vinyl acetate (EVA) as EV-40LX of Mitsui Dupont and ethylene methyl acrylate (EM).
A) is Exxon XS-5508, and the weight ratio between EVA and EMA is 7: 3. And such a mixture with a diameter of 90
The mat was applied to the mat body 1 with a thickness of 200 μm using a mm extruder to prepare a mat. The non-slip layer 2 made of such a material has an adhesive force on the surface, and adheres to the floor by this adhesive force.

The physical properties of this prototype mat were measured at four points: physical property change with temperature change, washing resistance, heat resistance, and adhesive force change with time. The size of the prototype is 25 mm width x 10 cm.
It was decided to apply a load by making two reciprocations on a kg roll. Hereinafter, each physical property will be described.

Physical Property Change with Temperature Change The temperature of the floor on which the trial mat was mounted was changed from 0 to 40 ° C., and the physical properties of the mat were measured. The measurement results are shown in Table 4 below. In addition, the measuring method was as follows. This prototype was placed on the floor, a load was applied by reciprocating two 1 kg rolls, and the adhesive was measured after being left at each temperature for 30 minutes.

[0021]

[Table 4]

In a temperature range of 0 to 40 ° C., which is a daily use temperature range, there is no resin adhesion and good adhesiveness.

Washing resistance Also, the washing resistance of the prototype was measured. The measurement results are shown in Tables 5 and 6 below. The measurement method is as follows.
Liter and 25 g of neutral detergent, wash for 10 minutes,
Minutes, dehydrate and dry with hot air at 40 ° C for 15 minutes, then room temperature (20 ° C)
And the procedure of attaching to the floor and measuring the adhesive strength was repeated.

[0024]

[Table 5]

[0025]

[Table 6]

It can be seen that the adhesiveness hardly deteriorates even after repeated washing.

After attaching the heat-resistant prototype to the floor, the temperature of the floor was set to 40 ° C., a load of 30 kg was left for 40 hours, and then the prototype was peeled off. As a result, the resin was peeled off without adhering to the floor, so that it can be said that the heat resistance at about 40 ° C. is good.

Adhesive force change with time Change After attaching the prototype to the floor, deterioration and discoloration of the adhesive force were observed. The observation results are shown in Table 7 below.

[0029]

[Table 7]

Even after a lapse of one month, the adhesive strength remains unchanged, and no discoloration is observed.

FIGS. 3 and 4 show an embodiment in which the surface shape of the anti-slip layer 2 is modified. That is, after coating the anti-slip layer 2, a large number of strip-shaped concave portions 3, 3,... Are formed by using a doctor knife.

The anti-slip layer 2 of the mat shown in FIGS. 1 and 2 has an extremely strong adhesive property as described above, and when placed on an object having a high degree of flatness, such as a floor carpet, peels off even if it is lifted for washing. Needs strong force, but the concave parts 3, 3 ...
The adhesive force is weakened by that amount, and it becomes the starting point of peeling, so that peeling can be performed easily.

The shape of the concave portion is not limited to a stripe shape, but may be an appropriate pattern such as a large number of circles. Further, a pattern in which the concave portion occupies more area than the other portions, that is, a pattern having a large number of round protrusions may be used. In addition, the mat body 1 is not limited to a woven fabric, and a non-woven fabric can be used. The material can be selected from a wide range such as a fiber such as cotton, a synthetic fiber such as nylon, and a synthetic resin film such as a polyester film. Further, the present invention can be applied to all mats laid on the floor, such as kitchen mats and entrance mats, and can have any shape such as an elliptical shape and a rectangular shape.
