DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to inorganic floors such as condominiums, office buildings, hotels and restaurants, public facilities such as schools, government offices, underground passages, and existing floors and stairs in buildings such as baths and saunas. The present invention relates to a non-slip construction method for an inorganic flooring material suitable for application to a material.

[0002]

2. Description of the Related Art In this type of building, inorganic flooring materials such as tiles, terrazzo, enamels, natural stones or artificial stones have been widely constructed in response to the recent upscaling.
Due to its inorganic nature, it has a low coefficient of friction when wet with water (wet state), which increases the risk of pedestrians (especially elderly and children) slipping and falling, especially in public facilities. There is a strong social demand for improving the slip resistance of inorganic flooring materials.

Conventionally, as a non-slip method of the inorganic flooring, a non-slip coating (for example, a coating in which an aggregate such as silica sand is mixed with a urethane resin or an epoxy resin) is applied to a walking surface of the inorganic flooring. Non-slip material (for example, a sheet in which mineral particles are attached to the surface of a polyethylene film or aluminum film, or a rubber or plastic mat) is applied to the walking surface of an inorganic floor material. Have been.

[0004]

However, in the above-mentioned construction method, not only the texture of the inorganic flooring material is changed by the paint, but also the curing and drying must be performed for a predetermined period after the construction, so that the walking is performed immediately after the construction is completed. In addition, there was a problem that the aggregate of the surface layer was peeled off due to aging, and maintenance was required each time.

On the other hand, in the above-described method, not only does the texture of the inorganic flooring change depending on the thin material, but if the inorganic flooring has irregularities, it is necessary to adjust the base in advance, and if the thin material comes off, Had the problem of causing a stumbling block.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a method for preventing slippage of an inorganic flooring material capable of improving the slip resistance in a wet state without changing the texture.

[0007]

That is, according to the present invention, the walking surface (2a) of the inorganic flooring material (2) is cleaned and degreased, and then the walking surface of the inorganic flooring material is measured in microns. A concave portion (3) having the size of (1) is formed, and then the walking surface of the inorganic flooring is neutralized and washed with water. Then, the walking surface of the inorganic flooring is dried to remove moisture. It is constituted as follows.

The numbers and the like in parentheses are for convenience showing the corresponding elements in the drawings, and therefore, the present invention is not limited to the description on the drawings. The same applies to the fields of “Claims” and “Action”.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an inorganic flooring to which one embodiment of the non-slip construction of an inorganic flooring according to the present invention is applied.
(A) is a perspective view thereof, (b) is an enlarged sectional view thereof, and FIG. 2 is a graph showing a result of a slip test of an inorganic floor material when a hard sole shoe for men is used. FIG. 3B is a graph showing the results of a slip test of an inorganic flooring when using soft-soled shoes for men, and FIG. 3A is a graph showing water + dust. The graph of a spraying state, (b) is a graph of an oil spraying state.

The non-slip construction of the inorganic flooring according to the present invention is performed in the following procedure.

First, after cleaning the walking surface 2a of the existing inorganic flooring material 2, a degreasing process is performed.

Next, on the walking surface 2a of the inorganic flooring material 2, a large number of concave portions 3 having a size of a micron (1/1000 mm) are formed uniformly over the entire surface of the walking surface 2a. To do so, a specific liquid agent (a liquid agent containing ethylene glycol, monobutyl ether, fluorine ion, ammonium ion, and sulfate ion as a component) is applied and diffused on the walking surface 2a of the inorganic flooring 2, and the walking surface 2a is brushed with a mat brush. Perform processing. Then, a recess 3 having a size of a micron unit is formed on the walking surface 2a of the inorganic flooring material 2.

Next, after a neutralization treatment is applied to the walking surface 2a of the inorganic flooring material 2, washing and washing are performed. Baking soda and the like can be used as the neutralizing agent.

Finally, the walking surface 2a of the inorganic flooring 2 is dried to remove moisture, and the non-slip construction of the inorganic flooring 2 is completed.

As described above, the non-slip construction of the inorganic flooring material 2 can be carried out quickly in a short time, not only is it possible to walk immediately after the completion of the construction, but also the base material is adjusted in advance even if the inorganic flooring material 2 has irregularities. No need.

The inorganic flooring material 2 on which the anti-slipping work has been completed as described above exhibits excellent anti-slip properties when wet with water. That is, when walking in a state where water is accumulated in the concave portion 3 of the inorganic flooring material 2, the water in the concave portion 3 is pushed out by the treading force during walking, and the inside of the concave portion 3 is in a negative pressure state. As a result, the shoes or bare feet are sucked to the walking surface 2a of the inorganic flooring material 2 by the sucker action, so that the slip resistance of the inorganic flooring material 2 is improved. Further, since the concave portion 3 formed on the walking surface 2a of the inorganic flooring 2 has a size of a micron unit, the texture of the inorganic flooring 2 does not change.

In order to confirm the above-mentioned effects (improvement of anti-slip property), an inorganic flooring material to which the present invention is applied (the present invention) and an inorganic flooring material having no micron-sized concave portion 3 (Conventional product) and JIS A 5705 (19
92) A floor material slip test was performed in accordance with the floor material slip test method (oblique tension type) in the Appendix, and the slip resistance of the two was compared. That is, as the material of the sliding piece, two types of men's hard sole shoes and soft shoes for men were used, and the surface state of the sliding piece was water +
Dust scattering state (tap water and test dusts 7 and 1 specified in JIS Z 8901 in a mass ratio of 20:
A mixture of 1: 9 was sprayed at a rate of 400 g / m ² ) and an oil sprayed state (edible rapeseed oil (JAS vegetable oil / fat 32) was sprayed at a rate of 40 g / m ² ).
Using the seeds, a slip test was performed under the conditions of a temperature of 20 ° C. and a humidity of 50%, and a slip resistance coefficient (CSR) was calculated from the maximum tensile load (Pmax). The results are shown in Tables 1 and 2 and FIGS.

[0020]

[Table 2]

As apparent from FIGS. 2 and 3, the slip resistance coefficient (CSR) of the product of the present invention (solid line) is larger than that of the conventional product (dashed line) under any conditions. In particular, in the combination of men's hard sole shoes and oil-sprayed state, C.I. S. R = 0.097 s, whereas the product of the present invention has C.I. S. R = 0.289 s, which is about three times higher, and it has been proved that the product of the present invention is superior to the conventional product in the slip resistance.

[0022]

As described above, according to the present invention,
The walking surface 2a of the inorganic flooring 2 is cleaned and degreased, and then the recess 3 having a size of a micron unit is formed in the walking surface 2a of the inorganic flooring 2, and then the inorganic flooring 2 is formed. The second walking surface 2a is subjected to a neutralization treatment and then washed with water, and then the walking surface 2a of the inorganic flooring material 2 is dried to remove moisture. When walking in the walking, the water in the recess 3 is pushed out by the treading force at the time of walking, and the inside of the recess 3 is in a negative pressure state. In addition, it is possible to improve the slip resistance in a wet state without changing the texture of the inorganic flooring material 2.

In addition, unlike the conventional method using a non-slip coating, not only is it possible to walk immediately after the completion of construction, but also excellent in maintainability. Further, unlike the conventional method using a non-slip thin material, even if the inorganic flooring has irregularities, adjustment of the base is not required, and there is no possibility of causing a stumbling.
