BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail with reference to the drawings showing the embodiments.

1 and 2 are a sectional view and an enlarged sectional view of an essential part showing an embodiment of an anti-slip rug according to the present invention. In this non-slip rug, a felt-like non-woven fabric 3 is laminated on a back face 2 of a rug original fabric 1, and a foam layer 4 in which a synthetic rubber or a plastic resin is mixed with a microcapsule foam 8 ... , Partially laminated with smooth floor anti-slip part 6 ...
And the remaining portion (the exposed portion of the non-woven fabric) is used as the anti-slip portion 7 for pile-like flooring material.

In the original rug 1, the pile 10 is densely formed on the base cloth 11, and the pile 10 is attached to the back surface of the base cloth 11 to prevent the pile 10 from being pulled out.
12 is coated (for example, a tufted carpet stock), and the back surface 2 of this adhesive layer 12 is provided with a non-woven fabric 3
Are fixed with an adhesive. As an adhesive,
200 parts by weight of SBR latex (solid content 50% by weight), 3 parts by weight of surfactant (solid content 35% by weight) and filler {calcium carbonate (solid content 100% by weight)} 400 parts by weight and thickener (solid content 5 parts by weight) and 40 parts by weight of water are preferred.

The non-woven fabric 3 is made of polyester or polypropylene having a cotton thickness of 1 to 80 denier and has a thickness of 0.2.
mm to 10 mm, basis weight 15 g / m ² to 600 g / m ² , density 0.01 g
/ Cm ^{3 to} 0.90 g / cm ^3, and those having an appropriate fluff are suitable. If the thickness is less than this lower limit, the slip-proof effect on the pile floor material is reduced, and if it is more than the upper limit, it is uneconomical and difficult to fold. Further, in the case of a nonwoven fabric having a basis weight smaller than the lower limit, the adhesive layer for preventing pile removal oozes out, which becomes a factor to impede the anti-slip effect. If it is larger than the upper limit, it is very uneconomical. Regarding the density, if the density is less than the lower limit, tearing of the non-woven fabric is likely to occur, and if it is more than the upper limit, the drying property at the time of processing is deteriorated, causing a problem of uneconomicality due to a decrease in productivity.

The foam layer 4 is made of styrene / butadiene rubber (SBR), ethylene vinyl acetate copolymer (EV).
A), methyl methacrylate / butadiene rubber (MB
It is formed by applying a resin composition prepared by blending heat-expandable microcapsules with an anti-slip resin such as R) or acrylic resin on the back surface 5 of the nonwoven fabric 3 and then heating and foaming.

More specifically, in the case of an acrylic resin, for 100 parts by weight of an acrylic resin (solid content 50% by weight), thermally expandable microcapsules {Nippon Philite Co., Ltd. product "Expansel 053wu80" (solid content 75 (Non-floss) resin composition A in which 4% by weight of (% by weight)) is blended, is used as the saucer container portion 13 of the roll coater apparatus E shown in FIG.

Here, the roll coater device E will be described. The two upper and lower rolls 14 and 15 that rotate forward and backward mutually.
The lower roll 15 is provided with a plurality of resin adhering portions 20 ... Having a predetermined width and height on the outer peripheral surface 16 in the circumferential direction. The resin-attached portion 20 ... is composed of an annular convex portion 17 ...
A plurality of ridges 18 formed by partially notching 17 and round, triangular and star-shaped ridges 19 protruding from the notches of the ridges 18 ... They are provided at a predetermined interval from each other. Further, below the lower roll 15, the saucer container part
13 is provided, and when the resin composition A is filled in the saucer container portion 13, the resin adhering portion 20 of the lower roll 15 ...
The lower outer peripheral surfaces 21 of the protrusions 17, 18 and the protrusions 19 are immersed in the resin composition A, respectively.

Then, the roll coater E is driven to pass the rug original fabric 1 having the nonwoven fabric 3 on the back side between the upper and lower rolls 14 and 15 (with the nonwoven fabric 3 facing the lower roll 15 side). Then, the resin composition A adhering to the outer peripheral surface 21 of the rotating resin adhering portion 20 is applied to the back surface 5 of the nonwoven fabric 3,
As shown in FIG. 5, linear (striped), round, triangular and star patterns are transferred.

When the rug roll 1 having the resin composition A applied to the nonwoven fabric 3 is dried by heating at 130 to 150 ° C., the microcapsules having a diameter of 10 to 20 μm in the resin composition A have a diameter of 40 to 40 μm.
It expands to 80 μm, and the volume becomes about 60 times, and foam 8 is formed, and this foaming forms a foam layer 4 having minute projections 22 ... Formed (see FIG. 2).

The foamed layer 4 serves as a smooth floor material anti-slip portion 6 having a particularly large slip resistance (friction resistance) with respect to a so-called flooring. On the other hand, the remaining portion (the exposed back surface 5 of the non-woven fabric 3 on which the smooth floor material anti-slip portion 6 is not laminated) becomes a pile-like floor material anti-slip portion 7 which is particularly intricately entangled with a carpet or the like and has a large slip resistance.

However, the foam layer 4 is the back surface 5 of the nonwoven fabric 3.
It is desirable to laminate in an area of 0.3 to 80% of the entire surface, and if the foam layer 4 is less than 0.3%, the slip prevention effect for the smooth floor material of the smooth floor material 6 (such as wood flooring) cannot be sufficiently obtained. If it is more than 80%, the slip prevention effect for the pile floor material (carpet, etc.) of the slip floor portion 7 for the pile floor material cannot be sufficiently obtained.

Further, referring back to FIG. 3, the lower roll of the roll coater device E is used to obtain the above-mentioned 0.3-80% laminated area.

It can be determined by setting the width dimension W (or the mutual spacing dimension). Further, the annular convex portion 17 and the convex strip portion 18 are formed in a wavy shape,
The convex portion 19 may be of a letter type, and the smooth floor anti-slip portion 6 may represent various patterns, letters, figures, symbols and the like. Generally, in the distribution process, the mark is effective because it is handled in a state that it is wound so that the back surface is on the outside.

In addition to the roll coater device E, for example, a known dot coating device (not shown) may be used to apply the resin composition A mixed with microcapsules to form the foamed layer 4. is there.

As shown in FIG. 5, when the anti-slip rug of the present invention is laid on the floor surface 30a of the smooth floor material 30 such as smooth and hard wood flooring, the partially formed smooth floor material. The anti-slip parts 6 ... Contact the floor surface 30a. When the anti-slip rug is pulled in the direction of the arrow (horizontal direction), the rough recesses 23 of the anti-slip part 6 for smooth floor material (see FIG. 2) absorb the dust existing between the floor surface 30a and the rug. Along with
The protrusions 22 ... Adhere to the floor surface 30a to increase the wear coefficient, exhibiting a slip-preventing effect, and suppressing slipping of the rug.

Further, as shown in FIG. 6, when an anti-slip rug is laid on a pile-like floor material 31 (having cushioning properties) typified by tufted carpet, dense piles 10 are formed.
The smooth floor 6 anti-slip portion 6 and the pile floor anti-slip portion 7 come into contact with. Then pulling in the direction of the arrow (horizontal direction)
The fibers of the slip prevention part 7 (nonwoven fabric 3) for pile-like flooring are pile 10
It entangles with ..., which exerts an anti-slip effect and prevents the rug from slipping.

FIG. 7 shows another embodiment of the anti-slip rug of the present invention, which is formed on the back surface 26a of an electric carpet 26 having an electric heater 25 therein (as described above), and is made of felt-like nonwoven fabric 3 The foam layer 4 in which the foam 8 of the heat-expandable microcapsule is mixed in the synthetic rubber or plastic resin is partially laminated on the back surface 5 of the non-woven fabric 3 --- an area of 0.3 to 80% of the entire back surface 5 --- Is laminated to form a slip resistant portion 6 for a smooth floor material, and the rest is a slip resistant portion 7 for a pile floor material.

More specifically, as shown in FIGS. 3, 4 and 7, polyester felt-like non-woven fabric 3 having a weight of 200 to 500 g / m ² is coated with an acrylic resin and thermal expansion in a roll coater device E. The resin composition A in which the functional microcapsules have been prepared is applied and heat-dried to form the anti-slip portion 6 for a smooth flooring material having a design pattern, thereby obtaining the backing material 33.

Next, the back material 33 is placed on the back surface 26a of the electric carpet 26. At this time, the aluminum sheet 28, then the electric heater 25, and the surface material 27 in which the piles 10 are densely stacked on the back surface material 33 are sequentially laminated with an adhesive material or an adhesive sheet,
A slip-proof electric carpet is obtained by integrating the whole with a hot press heated to 140 to 150 degrees.

In this anti-slip rug (electric carpet), the anti-slip portion 6 for smooth flooring is used for smooth flooring such as wood flooring, and the pile-like flooring is used for tufted carpet. The pile-like floor material anti-slip parts 7 each exhibit an anti-slip effect and prevent slippage such as lateral slippage.

[0029]

EXAMPLES Next, a slip resistance test was conducted on the anti-skid rug of the present invention and a conventional product, and the results are shown in Table 1.

[0030]

[Table 1]

A vertical load of 18 kg was evenly applied to a 20 × 20 (cm) test sample, the test sample was pulled horizontally along various floor materials, and the maximum static friction force was measured by an autograph to determine the friction coefficient. I asked.

From these results, the product of the present invention and the conventional product show similar sliding resistance (friction coefficient) to the wooden floor material, the vinyl chloride floor and the folding table, but the invention of the present invention can be applied to the carpet. The product shows a considerably larger slip resistance (friction coefficient) than the conventional product.

Therefore, according to the anti-slip rug of the present invention, an excellent anti-slip effect can be obtained on not only smooth floor materials such as wood flooring but also vinyl floors, folds, and non-smooth pile floor materials. It can be said that it works.

[0034]

Since the present invention is configured as described above, the following effects can be obtained.

Small protrusions 22 ... (See FIG. 2) generated by the microcapsule foam 8 (according to claim 1, 2, 3 or 4) are effective for the mating floor material. To increase the slip resistance, and moreover, the slip resistance is further increased by the synergistic effect of the irregularities of the fibers of the non-woven fabric 3 and the convex portions 22 ... Of the foam layer 4 attached to the fibers. In addition, the slip prevention portion 6 for the smooth floor material exerts a slip prevention effect on the hard smooth floor material 30 such as wood flooring, and the slip prevention portion 7 for the pile-shaped floor material.
Exhibits an anti-slip effect on the pile-like floor material 31 such as tufted carpet. That is, since the anti-slip effect is effective for various floor materials, the place to be laid is not limited, and it is possible to prevent the rug from being positioned little by little in each room, and it can be used safely.

Further, the anti-slip portion 6 for smooth floor material (foam layer 4)
Since it is a partial formation, the coating amount is small and it is economical. In particular, when the area of 0.3 to 80% is used as the slip prevention portion 6 for the smooth flooring material, it effectively acts as a non-slip material on each type of flooring material.

(According to the anti-slip rug according to claim 3 or 4, the anti-slip portion 7 (nonwoven fabric 3) for pile-like floor material is excellent in air permeability, so that in winter, a smooth floor such as wood flooring is used. Condensation does not occur between the back surface material 33 of the electric carpet 26 laid on the material 30 and the floor surface. Therefore, the anti-slip effect does not decrease, and it can be used satisfactorily throughout the year.

(According to the anti-skid rug according to claim 5) Characters and figures such as product names and beautiful designs are displayed on the anti-slip part 6 for smooth flooring so that the type of rug can be used in the distribution process. Can be easily identified and PR can be given to consumers and the like.
