Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floor-shrine that has excellent water permeability and is hard to slip when wet.

(Prior Art) Floor materials used in areas where water is used, such as bathrooms, galleys, toilets, and entrances, are required to have properties that prevent them from slipping when wet.

Conventionally, the following techniques have been proposed regarding such floor materials.

(2) By connecting and solidifying the surface of aggregate such as sand with a particle size of 0.3+nm or more with a thermosetting resin, a water-permeable resin concrete layer with continuous water-permeable pores formed between the aggregates is formed. The water-permeable holes formed in this water-permeable resin concrete layer allow water to permeate from the surface of Floor-+4 to the back side, preventing slippage when wet (for example, see Utility Model Publication No. 15308/1983) ).

■ By scattering plastic particles on the surface of a floor material made of vinyl chloride resin, non-slip properties are imparted to the surface of the floor material (for example, U.S. Pat. No. 4,196,
No. 243 and U.S. Pat. No. 4,239,797).

■In addition to forming unevenness on the surface of the flooring material, the surface is also roughened (
Also, by providing an elastic body on the surface, non-slip properties are imparted to the flooring material (for example, U.S. Pat. No. 4,336
, 293 and U.S. Pat. No. 4,403.009).

(Problem to be Solved by the Invention) However, in the above configuration (①), since the diameter of the water permeation hole is large, foreign matter enters the inside of the water permeation hole along with water.
The disadvantage is that it can become clogged and reduce water permeability.

In the configuration (■) above, since the plastic particles are used to prevent slipping, when the plastic particles get wet, a water film is formed on the surface of the plastic particles, which causes the coefficient of friction to drop significantly compared to when dry, causing slippage. There are some drawbacks that give rise to this. Also,
Since this floor-moon prevents slipping by providing irregularities on its surface, dirt tends to accumulate in the recesses and the surface is also poor in smoothness.

Similarly to the above structure (2), since slipping is prevented by providing irregularities on the surface of the floor material, it is easy to get dirty and has the drawback of poor surface smoothness.

Therefore, the present inventor prepared a floor material composition by mixing powder and granules with a binder such as a thermosetting resin, and by pressure-molding this floor material composition, a plate-shaped floor was produced. - We considered manufacturing materials. The floor material obtained by this method has the advantage that it has fine water-permeable pores and is hard to slip when wet, and has excellent surface smoothness and is hard to stain.

However, since the above-mentioned floor material composition contains a large amount of powder and granules having poor fluidity, molding pressure is applied unevenly when the floor material composition is molded. As a result, in areas where strong pressure is applied, the binder oozes out, resulting in uneven floor appearance, and in areas where pressure is not applied, the strength of the floor material decreases. was.

The present invention solves the above-mentioned drawbacks, and its purpose is to:
It is an object of the present invention to provide a floor material that has long-term non-slip performance even under usage conditions where wet conditions frequently occur. Another object of the present invention is to provide a floor material that has excellent surface smoothness, is hard to stain, has a good appearance, and has uniform performance throughout.

(Means for Solving the Problems) In the floor shed of the present invention, a floor material composition containing a powder and a binder is processed through a cushion sheet that can be elastically and/or plastically deformed. Obtained by pressure molding,
The water permeability is 1.0 to 0.01 cc/c seedling-hr, and the surface roughness is 10 μm or less, thereby achieving the above objectives.

The present invention will be explained in detail below.

The floor material according to the present invention comprises a powder material, a thermosetting resin,
A floor material composition prepared by blending a binder such as cement in a predetermined ratio is pressure-molded into a plate shape. Light aggregates such as sepiolite and wollastonite can be used as the granular material, and it is preferable that the granular material is contained in an amount of about 75 to 85% by weight based on the floor material composition.

If the content of the powder or granules in the floor material composition is less than 75% by weight, the resulting floor material will have poor slip resistance, and the content of the powder or granules in the floor material composition will be poor. When the content exceeds 85% by weight, the resin content decreases, resulting in poor moldability.

Examples of the thermosetting resin include unsaturated polyester, diallyl phthalate resin, epoxy resin, and phenol resin.

To produce a floor material, the floor material composition is
The floor material composition is filled in a plate shape into a mold, a cushion sheet is interposed between the floor material composition and the mold, and the floor material composition is press-molded in that state. The cushion seat is
For example, a plastically deformable sheet such as a felt sheet, an elastically deformable sheet such as a rubber sheet, or a plastically deformable and elastically deformable sheet is used,
Or you may use them together. By pressure-molding the floor material composition through the cushion sheet, the pressure force received from the mold is applied uniformly to the floor material composition by deforming the cushion sheet. be able to.

The floor material obtained in this manner contains a predetermined amount of powder and granules, so that the interior thereof is provided with continuous water permeable pores, and the interior thereof has a porous structure. Therefore, the water existing on the surface of this flooring material flows downward through the water permeable holes, and when it gets wet, there is no large amount of water present at the interface between the surface of the flooring material and the object being contacted. It should be possible to prevent the coefficient of friction when wet from dropping significantly compared to when dry. In addition, since the diameter of the water permeation holes formed in the surface layer is relatively small, impurities do not penetrate into the water permeation holes and clog them, and the impurities on the surface of the floor-shrine (=
Since it only gets on the skin, you can wash away this contaminant with water.

The water permeability of the obtained floor material is 1.0 to 0.01 cc.
/cm2fl-hr, preferably 0.5-0.05cc
/cJ-hr, and the surface roughness of the floor material JI
The centerline average roughness (Ra) shown in S standard BO601 is 10 μm or less. The water permeability of the floor material is 1
, if it exceeds 0cc/cf/hr, there is a risk of clogging, and the water permeability is 0.01cc/c/c.
If it is less than +flhr, it tends to slip when wet. When the surface roughness of the floor material exceeds 10 μm, the feel to the touch deteriorates.

The thus formed flooring material is used, for example, as a flooring material for sanitary products, toiletries, entrances, bromnets, hellandas, etc., or by laying it on gymnasium floors, poolsides, pavements, etc.

(Example) Hereinafter, the present invention will be specifically explained based on Examples.

A floor material composition was prepared by mixing 20 parts by weight of actual soil cement and 1 to 80 parts by weight of sepiolye. Next, as shown in FIG. Floor material composition #4 and shoes 1 and 5 made of felt sheets were placed in an overlapping state, and then the upper die 2 was lowered to pressure-form the floor material composition 4. Thereafter, this molded product was cured and cured to obtain a floor material.

Next, the water permeability, surface roughness, and slip resistance of the obtained floor material were measured, and the appearance, strength, and clogging of the floor material were evaluated. The results are shown in Tables 1 and 2.

Note that the surface roughness was measured in accordance with JIS standard BO601. The measurement of slip resistance was performed as follows.

As shown in FIG. 2, the floor material 1 is tilted at a predetermined angle, a tester stands on the floor material 1, and the inclination of the floor material 1 when the tester slides off the surface of the floor material 1. Measure the angle θ and calculate the friction coefficient from this sliding angle θ; t
Anθ was determined. And the friction coefficient tanθd when dry
The coefficient of friction tanθwet when wet with water against ry is determined, and this value tanθwet/lanθdry is ◎ if it is 1.0 or more, ○ if it is 0.9 or more and less than 10, △ if it is 0.75 or more and less than 0.9. Indicated as ×.

In addition, clogging evaluation was performed by dispersing talc powder (10 μm or less) in water (0.2 g/cc) and dispersing 50 cc of this liquid.
Sprayed on a 100x100111m test piece at the appropriate time, talc powder remains on the surface and can be washed off later.
Items in which talcum powder leaked out from the back side or caused clogging are marked with an x.

The surface roughness was determined by measuring the center line average roughness (Ra) according to JIS BO601 using a measuring device (needle; diameter 2 μm, cutoff 0.8
mm). As for the texture, a sensitivity test was conducted using the palm of the hand, and those with roughness were marked with an x, and those with no roughness were marked with an ○.

A floor material was obtained in the same manner as in Example 1, except that the floor material composition was pressure-molded without using the comparative flame cushion sheet, and the appearance and strength of this floor material were the same as in Example 1. evaluated. The results are shown in Table 2.

(The following is a blank space) +1 From the results in Table 1, it can be seen that those with low water permeability have poor slip resistance when wet with water. Also, the binder
Those formed from a floor-shrine composition containing 25 to 15% by weight of the earthen composition, and whose water permeability is in the range of 1.0 to 0.01 cc/c hr. It can be seen that the texture, slip resistance, and clogging properties are excellent. Examples 1.2 and Comparative Example 7 do not cause clogging, have a sufficiently small amount of water permeation, and have impurities remaining on the surface. These have smooth surfaces and small water permeability, so they can be washed away to remove impurities.

From the results shown in Table 2, it was confirmed that by using the Kunjon sheet, the material composition could be uniformly pressed, its appearance improved, and its strength could be made uniform.

(Effects of the Invention) As described above, according to the present invention, the coefficient of friction in a wet state does not decrease significantly compared to that in a dry state, so it is difficult to slip when wet, and the surface is not clogged with foreign matter.
A foot shrine that is hard to slip over a long period of time can be obtained.

Moreover, the surface smoothness can be improved, making it difficult to stain, and the sensitivity can also be improved.

Furthermore, since pressure can be applied almost uniformly during molding, the binder does not ooze out onto the surface, resulting in a floor material that has a good appearance and uniform strength throughout.
