On the other hand, as well as satisfying the required performance in practical use, new demands for flooring materials have begun to emerge from the viewpoint of safety, comfort or environmental considerations due to the growing awareness of the living environment of users. One of them is slip resistance. This is measured, for example, according to JIS-A1454 “Polymer-based tension flooring test method”. S. R. It is expressed by the standard value of slipperiness assuming the walking indicated by the value.
For floor sheets used outdoors, especially for stairs, balconies, and condominium corridors, various flooring materials with uneven surfaces have been put to practical use. As one of them, a non-slip floor material in which a raised printed pattern portion is formed on a substrate, and a point-shaped anti-skid small protrusion group made of a crosslinked resin is formed on the surface of the printed pattern portion by printing is integrally fixed. It has been known.

<First Embodiment>
〔Constitution〕
1A and 1B are cross-sectional views schematically showing a configuration example of the floor decorative material 10 according to the first embodiment of the present invention.
As shown in FIG. 1A, the floor decorative material 10 includes a slip-proof floor decorative sheet 1 and a floor base material 11. Further, the decorative sheet 1 for a non-slip floor includes a base sheet 2, a printing layer 3 formed on the base sheet 2, a transparent thermoplastic resin layer 4 formed on the printing layer 3, and a transparent thermoplastic resin. A topcoat layer 7 formed on the layer 4 is provided.

As the base material 11 for floors, south plywood plywood, particle board, medium density fiber board (hereinafter MDF), and normal plywood stipulated in Japanese Agricultural Standard can be used. Moreover, the base material which consists of wood powder addition olefin resin can also be used. The thickness of the floor substrate 11 is preferably about 3 to 25 mm.
The decorative sheet 1 for a non-slip floor has a plurality of (for example, many) convex portions 5 on the surface (the upper surface in FIG. 1), and a top coat layer 7 is provided on the surface. The top coat layer 7 enhances the weather resistance, scratch resistance, stain resistance and the like of the anti-slip floor decorative sheet 1. Further, the floor decorative material 10 is obtained by sticking the back surface (the lower surface in FIG. 1) side of the anti-slip floor decorative sheet 1 to the floor base material 11.

2A to 2D are plan views schematically showing a configuration example of the floor decorative material 10 according to the first embodiment of the present invention. As shown in FIG. 2A, each of the plurality of convex portions 5 in a plan view (hereinafter referred to as a planar shape) may be a rectangle (for example, a square). Moreover, as shown in FIG.2 (b), each planar shape of the some convex part 5 may be circular (for example, regular circle). Moreover, as shown in FIG.2 (c), each planar shape of the some convex part 5 may be a triangle (for example, regular triangle). Further, as shown in FIG. 2D, the planar shape of each of the plurality of convex portions 5 may be a cross shape (that is, a cross shape). In any case of FIGS. 2A to 2D, the arrangement of the convex portions 5 is a random arrangement (that is, an arrangement having no regularity). Since the convex portions 5 are randomly arranged, unpleasant rubbing noise associated with walking of a pet or the like is suppressed.
The decorative sheet 1 for a non-slip floor is provided with a printing layer 3 on a base sheet 2 to form a base layer. Printing is usually known. For example, a gravure printing method can be used.

  For the base sheet 2, for example, a vinyl chloride resin, an acrylic resin, a polyolefin-based polypropylene resin, or a polyethylene resin can be used. Of these, polyolefin resins can be preferably used in terms of environmental compatibility, processability, and cost. In addition, the grade and composition of the resin can be selected in consideration of ease of sheeting, printability, and suitability for bending.

  A transparent thermoplastic resin layer 4 is provided on the printing layer 3, and a plurality of convex portions 5 are formed on the surface thereof. The shape and size of each of the plurality of convex portions are, for example, the same as each other. The method of forming the transparent thermoplastic resin layer 4 may be a method of bonding a polypropylene film, or a method of forming the transparent thermoplastic resin layer 4 on the printing layer 3 using an extruder. The formation method of the convex part 5 may be a method of forming an uneven shape on the surface of the transparent thermoplastic resin layer 4 by heating and pressurizing using an embossing mold (so-called embossing). When forming the transparent thermoplastic resin layer 4 with an extruder, the convex part 5 can be formed in the surface of the transparent thermoplastic resin layer 4 with an embossing roll etc. immediately after extrusion.

If the convex portions are regularly arranged at regular intervals, such as a staggered lattice, for example, a rubbing sound accompanying walking of a pet or the like is generated at the same frequency, resonates and amplifies, and an unpleasant rubbing sound It is felt by human ears. In the present embodiment, since the convex portions 5 are randomly arranged, the frequency of the rubbing sound is not uniform, and the resonance and amplification of rubbing are suppressed. For this reason, suppression of an unpleasant rubbing sound that can be heard by the ear can be realized.
The random arrangement of the convex portions 5 may be arranged in consideration of having no regularity, and in that case, a certain effect can be expected. In addition, the random arrangement of the convex portions 5 becomes more effective by randomly arranging them using random number calculation.

  The convex portion 5 preferably has a height of 20 μm or more and 80 μm or less. If the height of the convex portion 5 is less than 20 μm, the anti-slip performance is inferior, and if it is larger than 80 μm, the production process such as difficulty in forming the convex portion shape becomes difficult. Here, the height of the convex part 5 is the height A from the bottom part to the top part of the convex part 5 as shown in FIG.1 (b). This height A is also the height difference between the adjacent convex portions 5 and concave portions 6 among the concave and convex portions formed on the surface of the transparent thermoplastic resin layer 4.

  Moreover, in this 1st Embodiment, as shown to Fig.1 (a), the height A of two or more convex parts among the several convex parts 5 mutually differs. For example, among the plurality of convex portions 5, the height A of the first convex portion 5a, the height A of the second convex portion 5b, and the height A of the third convex portion 5c are different from each other. , The height A is non-uniform (that is, different values). The height A is higher in the order of the first convex portion 5a, the second convex portion 5b, and the third convex portion 5c. Thus, in addition to the convex portions 5 being randomly arranged, the height A of the convex portions 5 is non-uniform, so that the frequency of the rubbing sound is further non-uniform. Thereby, resonance and amplification of rubbing can be further suppressed, and unpleasant rubbing sound heard by the ear can be further suppressed.

  3A to 3D are plan views showing the maximum length B of the convex portion 5 in plan view. As shown in FIG. 3A, the maximum length B of the square is the length of the diagonal line. Further, as shown in FIG. 3B, the maximum length B of a regular circle is a diameter. Moreover, as shown in FIG.3 (c), the maximum length B of an equilateral triangle is the length of one side. Moreover, as shown in FIG. 3D, the maximum length B of the cross shape is the length of both ends in the vertical direction (or horizontal direction).

  In each embodiment of the present invention, the maximum length B of the convex portion 5 is 300 μm or less, for example, 40 μm or more and 200 μm or less is preferable. If the maximum length B of the convex part 5 is less than 40 μm, the slip resistance may be inferior. Further, the surface density of the convex portions 5 (that is, the ratio of the convex portions per unit area in plan view) is preferably 0.05 or more and 0.5 or less. When this areal density is less than 0.05 or greater than 0.5, the slip resistance may be poor.

In the case the planar shape of the convex portion 5 is square, the surface density of the protrusions 5 can be expressed by n × B ^{2 /} C ^2. Here, C is the length of one side of a square arbitrarily defined in plan view, and n is the number of convex portions 5 included in the square. Moreover, when the planar shape of the convex part 5 is a regular circle, the surface density can be represented by n × (π / 4) × B ² / C ² . When the planar shape of the convex portion 5 is a triangle, the surface density can be represented by n × (√3 / 4) × B ² / C ² .

  A top coat layer 7 is provided on the outermost surface of the anti-slip floor decorative sheet 1. For the top coat layer 7, by using a cross-linked resin such as a thermosetting resin, an ultraviolet curable resin, or an electron beam curable resin, weather resistance, scratch resistance, stain resistance, etc. Can be strengthened. These resins may be used alone or in combination. For example, as the top coat layer 7, a plurality of resins among the above resins may be mixed and used, or one of the resins and a resin other than the above may be mixed and used. These resins may be applied using a known coating machine, and may be cured by irradiation with heat, ultraviolet rays or electron beams in accordance with the type of crosslinking. In addition, the shape of the convex part 5 formed on the surface of the transparent thermoplastic resin layer 4 is reflected on the top coat layer 7 formed thereon, and the convex part is also formed on the surface of the top coat layer 7.
