Description

  The present invention relates to a floor anti-slip treatment method and an anti-slip floor structure suitable for ceramic tile floors, and an anti-slip floor material.

  In general, ceramic floors are widely used as flooring materials for buildings such as commercial facilities and stores because they are glossy and have a high-class feeling and are maintenance-free. However, this ceramic tile floor is slippery because the floor surface is smooth, and particularly when the floor surface is wet with rain water or the like, it is more slippery and there is a problem that safety during walking is lowered.

  Therefore, a non-slip portion formed by mixing particles having a particle size of 0.1 mm to 1.0 mm with respect to the crosslinked resin and applying this to the floor material surface from the stencil opening of the roll screen is dispersed on the floor material surface. A fixed non-slip floor material has been proposed (see, for example, Patent Document 1).

  In addition, as an anti-slip flooring material having another configuration, an adhesive is applied to a smooth surface film in a pattern, and then the film surface is coated with particles having a particle size of 0.05 to 1.0 mm. Part of the particles to which no adhesive is applied is removed. Then, the obtained film-like pattern material is laminated with a base material such as a tile backing material of polyvinyl chloride (PVC) having a thickness of 0.5 to 5.0 mm by a press machine, and the particle assembly tip and the film smooth surface are laminated. An antiskid floor material having a substantially uniform surface height has been proposed (see, for example, Patent Document 2).

  In the invention described in Patent Document 1, since the particles are mixed in the crosslinked resin in advance, even if the crosslinked resin is sufficiently stirred, the particles are biased due to a difference in specific gravity, etc. There is a problem that it cannot be adjusted. In addition, there is a problem that the density of the particles in the anti-slip part is low and the anti-slip performance cannot be sufficiently improved by the particles. Moreover, since unevenness is formed on the floor surface by the anti-slip portion, there is a problem that the sharpness of the floor surface is lowered and the appearance and aesthetics of the floor are lowered. The sharpness means an index indicating how clearly and accurately the object image is reflected on the surface of the coating film.

  On the other hand, as described in Patent Document 2, when the particles are attached to the adhesive applied to the film, the particles can be arranged with almost no gap. However, since the thickness of the outer edge of the adhesive applied to the film is inevitably reduced, there is a problem that the adhesiveness to the particles at the outer edge is reduced. In addition, since the aggregate of particles is not covered with a coating agent, there is a problem that the particles are easily peeled off. The invention described in Patent Document 2 is basically intended to improve anti-slip properties and cleanability, and in Patent Document 2, the gloss of the floor is reduced by the anti-slip part, The problem that the sharpness is lowered is not described, is not even suggested, and there is no description of a configuration for ensuring glossiness and sharpness.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, the anti-skid floor structure 1 includes a plurality of anti-skid floor materials 4 that are laid and fixed on the floor slab 2 with an adhesive layer 3 therebetween without any gap therebetween. The floor material body 5, the anti-slip part 6 dispersed and fixed on the surface (upper surface) of the floor material body 5, and the coating layer 7 provided so as to cover the entire floor material surface including the anti-slip part 6 are provided.

  The flooring main body 5 can employ a well-known configuration made of ceramic, wood, stone, synthetic resin, or the like, and in particular, ceramic tiles made of ceramics are preferably used in order to improve glossiness. As the planar shape of the flooring main body 5, it is possible to preferably adopt a square shape or a rectangular shape so that it can be laid down on the floor slab 2 of the building. It is also possible to adopt.

  The anti-slip portion 6 is an assembly composed of a plurality of particles 8 bonded and fixed by an adhesive layer 9 and is accumulated so that adjacent particles 8 are in contact with each other. The number of stacked layers of the particles 8 is set to two in FIG. 3, but can be set to one, or can be set to a plurality of three or more. The thickness of the anti-slip portion 6 is preferably set to 100 μm to 400 μm because if it is too thick, the sharpness and cleanability are deteriorated, and if it is too thin, the anti-slip property and durability are deteriorated.

  The planar shape of the anti-slip portion 6 may be a circle as shown in FIG. 1 or a shape other than a circle, for example, a polygonal shape such as a single letter, a cross, a hexagon or a square as shown in FIG. You can also. In the case of forming a circle, the diameter is preferably set to 10 mm or less.

  As shown in FIG. 1, the position of the anti-slip portion 6 can be arranged at the intersection of vertical and horizontal grids, or can be arranged in other arrangements. Although the space | interval of the adjacent anti-slip | skid part 6 can be set arbitrarily, when the surface area of the anti-slip | skid part 6 becomes small, anti-slip performance will fall, and since glossiness will fall when too large, the surface area of the anti-slip part 6 has the flooring body 5's surface area. It is set to be 3 to 30% of the surface.

  As the particles 8, particles having an average particle diameter of 10 μm to 200 μm, preferably 50 μm to 150 μm can be suitably employed, but particles having other sizes can also be employed. Moreover, although the spherical shape can employ | adopt suitably the shape of the particle | grains 8, it is also possible to employ | adopt irregular shapes other than spherical shape. Furthermore, the particles 8 can be used in combination with a plurality of types of particles having different average particle diameters and / or shapes. By using multiple types of particles in combination, durability and anti-slip properties can be improved. As the material for the particles 8, a synthetic resin material such as polyurethane, polyester, polyvinyl chloride, acrylic, or polycarbonate can be used, and an inorganic material such as alumina, natural sand, silica sand, or silicon carbide can also be used. . In particular, since it is transparent and can prevent deterioration of the sharpness of the floor surface 10, it is preferably composed of transparent beads made of glass, acrylic, polycarbonate, or the like.

  The adhesive layer 9 for bonding the particles 8 to each other can be made of an adhesive composed of any component as long as it has low viscosity and can penetrate between the particles 8 constituting the anti-slip portion 6 and is cured and transparent. . For example, a silicone-based adhesive, an acrylic adhesive, a urethane-based adhesive, or the like can be adopted, but it is also preferable to use a coating agent that constitutes the coating layer 7 as an adhesive.

  The coating layer 7 is formed by applying a silicone-based coating agent to the floor surface 10. However, it is also possible to employ known floor coating agents such as acrylic and urethane other than silicone.

The coating amount of the coating agent can be arbitrarily set, but is 50 to 400 g / m ² , preferably 100 in order to sufficiently ensure the durability of the anti-slip portion 6 while sufficiently ensuring the anti-slip property in the anti-slip portion 6. It is preferable to set to ˜300 g / m ² .

  The glossiness of the surface of the non-slip floor structure 1 is such that the glossiness of the floor surface before the anti-slip treatment is ensured so that the glossiness and sharpness of the floor surface can be sufficiently secured and a good-looking and beautiful floor can be realized. 30% or more, preferably 50% or more. The glossiness is obtained when GLOSS268 manufactured by Konica Minolta is used as a glossiness meter and the measurement angle is set to 60 °.

  Since the antiskid floor structure 1 and the antiskid floor material 4 include the antiskid part 6 in which the aggregate of the plurality of particles 8 is fixed to the floor surface 10 by the adhesive layer 9, the antiskid performance can be improved. Moreover, since the surface area of the anti-slip portion 6 with respect to the floor surface 10 is set to 3 to 30%, the glossiness of the surface of the anti-slip floor material 4 is lowered and the sharpness is lowered while sufficiently ensuring the anti-slip property. And the deterioration of the cleaning property can be prevented. Moreover, since the coating layer 7 covering the entire floor surface 10 including the anti-slip part 6 is formed, peeling and breakage of the anti-slip part 6 can be effectively prevented, and the durability can be improved.

  Next, an anti-slip treatment method for a floor of an existing building will be described with reference to FIGS. In addition, this anti-slip treatment method can be applied to the floor of a new building, or can be applied to a floor material before construction on the building. When applying to flooring before construction to a building, in the following cleaning process to curing process, replace "floor surface" with "floor surface" and apply anti-slip treatment to the floor material surface. .

  First, in the pretreatment process, after dust and dirt on the floor surface 10 are removed with a vacuum cleaner, the floor surface 10 is cleaned with a paper waste soaked with acetone, and an unnecessary portion of the anti-slip treatment, for example, between floor materials Paste the masker to cover the joints.

  Next, in the masking step, as shown in FIG. 6A, a masking sheet 12 having a plurality of openings 11 is attached to the floor surface 10. As the masking sheet 12, for example, a grid-like vertical and horizontal intersection so that the anti-slip portion 6 has an appropriate size and has a thickness of 100 μm to 400 μm and an opening ratio of the opening 11 of 3 to 30%. What formed the opening part 11 of diameter 10mm or less in a position is employ | adopted. Further, as the masking sheet 12, it is preferable to employ a sheet other than the white type so that the filling leakage of the particles 8 in the next step can be easily confirmed visually.

  Next, in the particle filling step, as shown in FIG. 6B, after the particles 8 are dispersed on the masking sheet 12, the metal spatula 13 is moved while being obliquely applied to the upper surface of the masking sheet 12, As shown in FIG. 6C, the opening 11 is filled with a necessary amount of particles 8 and unnecessary particles 8 on the masking sheet 12 are removed.

  Next, in the adhesive application step, as shown in FIG. 7 (a), the adhesive 9A made of a silicone-based coating agent is sprayed using a spray-type spreader, and then the metal spatula 14 is applied to the masking sheet. 12, the adhesive 9 </ b> A is filled in the opening 11, the adhesive 9 </ b> A is filled between the particles 8 without a gap, and the unnecessary adhesive 9 </ b> A on the masking sheet 12 is removed. However, as the adhesive 9A, it is possible to adopt a material other than the silicone-based coating agent.

  Next, in the drying step, the adhesive 9A is dried. The drying time depends on the outside air temperature and the air permeability of the building, but when a silicone-based coating agent is used as the adhesive 9A, it is left to dry at room temperature for 60 minutes to 120 minutes.

  Next, in the masking removal step, as shown in FIG. 7B, the masking sheet 12 is removed and then the burrs are removed. Then, after removing masking and unnecessary maskers, the floor surface 10 is checked, and if there is a defective portion in the anti-slip portion 6, it is repaired.

Next, in the coating process, as shown in FIG. 7 (c), a silicone-based coating is applied using a spray-type spreader in the same manner as the adhesive application process so that the spray amount is 100 to 200 g / m ^2. The coating layer 7 is formed by uniformly dispersing the agent 7A on the floor surface 10.

  Next, in the curing step, the coating layer 7 is left until it is dried, and then the remaining masker is removed to obtain the anti-skid floor structure 1 as shown in FIGS.

  According to this anti-slip treatment method, the particles 8 are filled in the openings 11 dispersedly arranged in the masking sheet 12, and then the adhesive 9A is filled in the openings 11 to form the anti-slip part 6. 6, the particles 8 can be densely arranged without gaps, and the particles 8 can be arranged in a single layer or a multi-layer depending on the thickness of the masking sheet 12. Can be improved. Moreover, since the anti-slip | skid part 6 is distributedly arranged on the floor surface 10, by setting the surface area of the anti-slip part 6 with respect to the floor surface 10 appropriately, ensuring anti-slip property enough, It is possible to prevent the glossiness from being lowered and thus the sharpness and the cleaning property from being lowered. Furthermore, since the coating layer 7 is formed by applying the coating agent 7A to the entire floor surface 10 including the anti-slip portion 6, it is possible to effectively prevent the anti-slip portion 6 from being peeled off or damaged and to improve its durability. Furthermore, the floor anti-slip treatment method can be applied to the floor of an existing building, can be applied to the floor of a new building, or the floor before construction on the building. It can also be applied to the material.

Next, the evaluation test of the anti-slip treatment method will be described.
As shown in Table 1, as a masking sheet 12, a masking sheet 12 in which openings 11 are formed at the intersections of lattice-like vertical and horizontal directions, the opening ratio of the openings 11 and the diameter of the openings 11 are variously changed. A type of masking sheet 12 was used. In addition, glass beads having a diameter of 100 μm were used as the particles 8, and a silicone-based coating agent was used as the adhesive 9 </ ^b > A and the coating agent 7 </ ^b > A, and the application amount in the coating process was set to 150 g / m ² .

  Then, in the same manner as described above, the surface of the flooring was subjected to anti-slip treatment, 11 types of anti-slip flooring samples 4A were produced, and gloss and anti-slip properties were measured.

  Glossiness was evaluated by glossiness when measured at a measurement angle of 60 ° using GLOSS268 (manufactured by Konica Minolta) as a gloss meter. The results are shown in Table 1. In Table 1, the case where the glossiness of the floor material surface after the anti-slip treatment is 50% or more of the glossiness of the floor material surface before the anti-slip treatment is indicated by “◯”, and the case where it is less than 50% and 30% or more. The case where it is less than 30% is represented by “x”.

  The anti-slip property was evaluated by a slip resistance coefficient obtained using a slip tester (OY / PSM: developed at Tokyo Institute of Technology).

  Specifically, as shown in FIG. 8, a sliding piece 21 made of a rubber sheet for hard bottom men's shoes is attached to the bottom surface of a steel sliding piece base 20 having a size of 80 mm × 70 mm. Then, the anti-slip floor material sample 4A is horizontally installed on the work table 22 with the anti-slip portion 6 facing upward, and the pedestal 20 with the slide piece 21 attached is installed on the upper surface of the anti-slip floor material sample 4A. Then, at the moment when the vertical load 785N is loaded on the sliding piece 21 and the sliding piece 21 is brought into contact with the surface of the anti-slip flooring 4A, the tensile load speed of 785N / s is obliquely upward (in the direction of arrow P). ) Was measured, and the maximum tensile load (Pmax) was measured by dividing the maximum tensile load (Pmax) by the vertical load 785N to calculate the slip resistance coefficient (CSR value). The results are shown in Table 1. In Table 1, the case where the CSR value is 0.5 or more is represented by “◯”, and the case where the CSR value is less than 0.5 is represented by “x”.

  The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and it goes without saying that the configuration can be changed without departing from the gist of the present invention.
