Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patterned non-slip sheet used by being attached to a floor or the like, and a method for producing the same.

[0002]

2. Description of the Related Art FIG. 1 shows an example of a conventional non-slip sheet of this kind and a method of manufacturing the same. As shown in FIG. 1, in order to manufacture the non-slip sheet 1, an adhesive resin layer 12 is first adhered to the surface of a plastic film 11, and then a pattern 13 is formed on the adhesive resin layer 12 by plate-making printing using a rotary press or the like. Is printed, and the non-slip mineral particles 14 are attached. The non-slip sheet 1 manufactured in this manner is used by being attached to a floor or the like, and a non-slip effect is obtained by friction of the mineral particles 14. In addition, a decorative effect can be obtained by the pattern 13 printed on the adhesive resin layer 12.

[0003]

However, in the above-mentioned conventional non-slip sheet, the mineral particles 1 are printed after the pattern 13 is printed.
Since the color 4 is attached, the color and design of the pattern 13 are easily deformed by the mineral particles 14. For the same reason,
Since the mineral particles 14 are exposed and the degree of adhesion thereof is low, they are susceptible to water and moisture, and the mineral particles 14 are liable to be lost. Therefore, there is a problem that the anti-slip effect cannot be maintained well for a long time. In addition, since the printing of the pattern 13 is performed by plate-making printing, a colorful and clear pattern 13 cannot be obtained, and the manufacturing cost is high and the manufacturing time is long.
There is a drawback that it is not possible to flexibly cope with small-quantity multi-product production.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and a vivid and clear pattern can be obtained, a good anti-slip effect can be maintained for a long time, and the production cost and time can be reduced. It is an object of the present invention to provide a non-slip sheet and a method of manufacturing the same, which can reduce the number of sheets and can flexibly cope with low-volume multi-product production.

[0005]

In order to achieve this object, a non-slip sheet according to claim 1 of the present invention comprises a plastic film, a first adhesive resin layer attached to a surface of the plastic film, and a first adhesive resin layer. Numerous non-slip mineral particles attached to the surface of the adhesive resin layer, a second adhesive resin layer attached to the surface of these mineral particles, and a pattern layer transferred to the surface of the second adhesive resin layer by thermal transfer When,
It is characterized by having.

According to this non-slip sheet, the non-slip mineral particles are not exposed on the surface but are fixed while being sandwiched between the first and second adhesive resin layers. It is resistant to moisture and does not lose mineral particles. Therefore, the anti-slip effect can be favorably maintained for a long time. Further, since the printing of the pattern is performed by the direct printing method by thermal transfer, a clearer and more vivid pattern can be obtained as compared with the case of the conventional plate making printing. For the same reason, the production cost and time can be reduced, and it is possible to flexibly cope with small-quantity multi-product production.
The “pattern” in this specification widely includes colors and characters for decorating a sheet, in addition to shapes and pictures.

According to another aspect of the present invention, there is provided a method of manufacturing a non-slip sheet according to the present invention, comprising: attaching a first adhesive resin layer to a surface of a plastic film; A large number of non-slip mineral particles are adhered to the surface, and a second surface is attached to the surface of the attached mineral particles.
Attaching an adhesive resin layer, attaching a thermal transfer paper on which a pattern is printed to the surface of the attached second adhesive resin layer, and applying a predetermined pressure from above the attached thermal transfer paper under a predetermined heating condition. Thus, the first and second adhesive resin layers are softened and integrated with the mineral particles, and the pattern of the thermal transfer paper is transferred as a pattern layer to the surface of the second adhesive resin layer.

[0008] According to this method for manufacturing a non-slip sheet,
A non-slip sheet according to claim 1 can be manufactured, and thus the above-mentioned effects can be obtained. In addition, since both pressure-sensitive adhesive resin layers are softened and integrated with the mineral particles by heating and pressurizing during thermal transfer, a non-slip sheet having higher robustness can be obtained.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. FIG. 2 shows a method for manufacturing a non-slip sheet to which the present invention is applied. As shown in the figure, in this manufacturing method, first, a first adhesive resin layer 22 made of acrylic resin or the like is attached to the surface of a plastic film 21 made of PVC or the like. Next, a large number of non-slip mineral particles 23 are attached to the surface of the first adhesive resin layer 22. As the mineral particles 23, for example, quartz sand is used. Further, the mineral particles 23
Is adhered so as to cover the second adhesive resin layer 24. This second adhesive resin layer 24 is also similar to the first adhesive resin layer 22,
It is made of acrylic resin or the like.

Next, a thermal transfer paper 25 on which a predetermined pattern is printed in advance is attached to the surface of the second adhesive resin layer 24. Finally, using the press machine P, a predetermined pressure (for example, 4 kgf / cm ² ) is applied from above the thermal transfer paper 25 under a predetermined heating condition (for example, 220 ° C.) for a predetermined time (for example, 30 seconds).
Seconds), the pattern of the thermal transfer paper 25 is transferred as a pattern layer 251 to the surface of the second adhesive resin layer 24, and the manufacture of the anti-slip sheet 2 is completed.

As shown in FIG. 3, in the anti-slip sheet 2 manufactured as described above, the mineral particles 23 are not exposed on the surface, and between the first and second adhesive resin layers 22 and 24. Since it is fixed in the sandwiched state, it is resistant to water and moisture, and the mineral particles 23 do not drop. Therefore, the anti-slip effect can be favorably maintained for a long time. Further, in the manufacturing method of the present embodiment, in particular, both the adhesive resin layers 22 and 2 are heated and pressed during the thermal transfer.
4 is softened and integrated with the mineral particles 23, so that the antiskid sheet 2 having higher rigidity can be obtained.

In addition, since the printing of the pattern is performed by a direct printing method using thermal transfer, a brighter and clearer pattern can be obtained as compared with the case of the conventional plate-making printing. For the same reason, the production cost and time can be reduced, and it is possible to flexibly cope with small-quantity multi-product production.

The materials of the components described in the embodiment are merely examples, and any material exhibiting the function that each should have can be adopted. Further, the predetermined temperature, pressure, and time for performing the thermal transfer are not limited to those illustrated in the embodiment, but can be appropriately changed according to the room temperature, the material of the components, and the like.
