Abstract

PURPOSE: To obtain an extremely good antislip characteristic and to eminently improve the safety of matting by affixing and integrating an antislip sheet consisting of a thin material coated with a soft acrylic resin foam layer having open cells to the rear surface of the floor-contact part of a matting body. CONSTITUTION: The matting body 1 made of a foamed polyethylene is formed with plural lines of drain grooves 2 in parallel on its rear surface 1. The parts between the adjacent grooves and both ends thereof are formed as the band- shaped floor contact parts 3 projecting to a rear surface side. The antislip sheet 4 is affixed and integrated by thermal fusing, adhering, etc., to the rear surface of the floor contact parts 3. The antislip sheet 4 is formed by coating a fibrous base material 5 made of fiber cloth consisting of a synthetic fiber or natural fiber non-woven fabric or woven fabric with the soft acrylic resin foam layer 6 from it one surface side. This foam layer 6 is a microfoam consisting of the open cells of expansion magnifications of 2 to 6 times and is partly impregnated in the fiber base material 5. The sections of the cells are exposed on the surface 7 on the opposite side.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathroom mat such as a bath mat or a bath drain.

[0002]

2. Description of the Related Art Since the bathroom flooring material is dangerous when it easily slides on the floor surface, various measures have been taken to prevent slipping.

As such a non-slip means, conventionally, a suction cup is provided on the lower surface of the flooring material main body so that it is adsorbed on the floor surface (for example, Japanese Utility Model Publication No. 45-29338, Japanese Utility Model Publication No. 5).
No. 7-40389, No. 56-8545, No. 2
No. 32154) has been proposed most.

However, the suction cup type anti-slip means cannot be expected to be sufficiently effective against the force of skidding on the tile surface, and the floor surface is uneven. It was not possible to expect a sufficient anti-slip effect.

As disclosed in Japanese Utility Model Publication No. 59-32375, which was previously proposed by the present inventor, a non-slip material made of a rubber foam such as styrene-butadiene rubber is attached to the lower surface of the main body of the flooring material so as to be integrated. Although the modified products are also known, they have not been able to sufficiently satisfy the anti-slip effect especially on a wet floor surface.

On the other hand, the flooring material itself is replaced by that made of lightweight expanded polyethylene, and the ethylene-vinyl acetate copolymer (E
VA) A product is also provided, which is made of a resin foam and has a large number of anti-slip ridges formed on the lower surface thereof to improve the anti-slip effect by utilizing the relatively large weight of the flooring material main body. However, it is expensive in terms of material cost, and it is difficult to handle because it is heavy.

[0007]

SUMMARY OF THE INVENTION With the development of a non-slip material, the present invention has an excellent anti-slip action to further improve safety without impairing the advantages of a lightweight laying material such as a foam synthetic resin mat. It is intended to provide an improved bathroom floor covering.

[0008]

According to the present invention, a non-slip sheet is integrally attached to the lower surface of a flooring part of a flooring material, and the non-slip sheet is a thin fiber base material and has a foaming ratio. A bath lining material, characterized in that it has a soft acrylic resin foam layer having 2 to 6 times the number of open cells and the cross section of the cells exposed on the surface, and is made of a thin material that is partially impregnated. And

As the fibrous base material, woven or non-woven fabric made of natural fibers as well as synthetic fibers can be used, but it is preferable to use non-woven fabric or woven fabric made of polyester fiber in terms of strength, cost and the like.

The non-slip sheet has a thickness of 0.1 mm.
If it is less than the above range, a sufficient anti-slip effect cannot be exhibited, and it is difficult to manufacture itself. On the other hand, when the thickness exceeds 0.4 mm and is too thick, it is not possible to expect a particular increase in the anti-slip effect, but there is a cost disadvantage. Therefore, the thickness is 0.2-0.
It is preferable to use one with a range of 4 mm, especially 0.2
It is preferable to use one having a thickness of about 0.3 mm.

If the foaming ratio of the acrylic resin foam layer is lower than 2 times, the water absorption effect is poor and the slip preventing effect when laid on the wet surface becomes insufficient, and if it is higher than 6 times, the slip preventing effect is not achieved. The surface strength of the sheet is too weak to be easily damaged, and the anti-slip effect is also reduced. Most preferably, the center is 3 times and the range is 2.5 to 3.5 times.

[0012]

The fiber base material supplements the strength of the non-slip sheet itself, imparts tensile strength to prevent its damage, and increases the joint strength with the flooring body. The soft acrylic resin foam layer is a fine open-cell foam with an exposed cell cross-section, and due to the unique physical properties of the material, it has an excellent anti-slip function, while the floor surface Even when it is wet, it absorbs the water film to prevent the reduction of the anti-slip effect, and always exhibits a large slip resistance.

EXAMPLES In the examples shown in FIGS. 1 to 3, (1) is a foaming polyethylene main body, and a plurality of drainage grooves (2) are formed in parallel on the lower surface. Both ends are formed in a strip-shaped floor contacting portion (3) protruding to the lower surface side.

A non-slip sheet (4) is integrally attached to the lower surface of the floor-contacting portion (3) by means of heat fusion, adhesion or the like.

As shown in detail in FIG. 3, the non-slip sheet (4) has a non-fibrous fiber base material (5) made of a non-woven fabric or a woven fabric of synthetic fibers or natural fibers, from one side thereof. The soft acrylic resin foam layer (6) is coated. The acrylic resin foam layer (6)
Is a micro-foamed body with open cells having a foaming ratio of 2 to 6 times, part of which is impregnated in the fiber base material (5), and the surface (7) on the side opposite to the base material (5) has a cross section of the air bubbles. Is said to have been exposed. In other words, the surface of the skin layer does not have a non-porous skin layer, and has a water absorbing property.

The laying material body (1) is not limited to one made of foamed polyethylene, but may be a soft or hard one made of another foamed synthetic resin, or one called a wooden chair. May be

In order to confirm the anti-slip effect of the above-described floor covering according to the present invention, the following comparative test was conducted.

Test Piece 1 (Example) As shown in FIG. 4A, a square test piece having a side length of about 20 cm was taken from the laying material of the above example. here,
In the test piece 1, a drainage groove (2) having a width of 37 mm and a depth of 4 mm is located in the central portion in the width direction, and a pair of convex floor contact parts (3) (3) with a width of 70 mm are located on both sides thereof. I decided. As the non-slip sheet (4), a fiber base material (5) made of a polyester non-woven fabric coated with the soft acrylic resin foam layer (6) of triple foaming is used, and the fiber base material (5) side The surface was adhered to and integrated with the lower surface of the flooring part (3) of the flooring material body (1) by means of heat fusion.

Specimen 2 (Comparative Example) A non-slip sheet (1) made of a vacuum-formed polyethylene foam sheet was formed on the lower surface of the floor-contacting portion (3) of the flooring material body (1).
4) was adhered, and the above-mentioned test was performed by using a laying material in which a large number of hollow circular protrusions (15) (whose top surface is slightly hollow) are formed on the lower surface of the floor-contacting part (3). A test piece (B in FIG. 4) having the same size as the piece 1 was prepared. The material of the main body (1), the size of the drainage groove (2), etc. were the same as those of the test piece 1.

Test piece 3 (comparative example) A floor with a large number of circular non-slip projections (12) formed on the lower surface of a floor material body (11) made of a 15-fold foam of ethylene-vinyl acetate copolymer resin. A test piece having the same size as the test piece 1 (C in FIG. 4) was prepared from the material.

[Slip resistance test] Each test piece was placed on the tile surface, and a weight of about 10 kg was placed on the center of the test piece through a circular wooden patch plate having a diameter of 15 cm, and the test piece was placed on the test piece. The load required to slide the test piece on the tile surface was measured by pulling it horizontally at a speed of about 20 cm / min.

The sliding direction was examined in two directions, parallel and orthogonal to the drainage groove on the back surface of the test piece. Further, the contact surface between the test piece and the tile surface was examined for each of the wet conditions wet with water or soapy water. Soap water here is body shampoo (with Kao Biore U powder)
A solution prepared by dissolving 10 g in 1 liter of water was used. Also,
The tile surface is a matte square tile (94 x 94 mm)
Was constructed by using cement for joints. The test operation was repeated intermittently for about 10 seconds each to perform three times of sliding, and the average value of the tensile loads at that time was obtained.

The results of the above tests are shown in Table 1.

As is clear from the results shown in Table 1, the bathroom floor covering according to the present invention is extremely excellent when used on a wet floor surface even in the case of a lightweight synthetic foam floor covering. It also exhibits anti-slip properties and can significantly improve the safety of the floor covering in practical use.

Such an excellent anti-slip effect is due to the fact that it has a specific expansion ratio, open cells, in addition to the inherently high friction coefficient of the low-foaming soft acrylic resin foam layer. , It is considered that due to the exposed bubble cross section on the surface, the non-slip sheet quickly absorbs water between contact surfaces and exhibits a stable anti-slip action even when laid on a wet surface. To be
