DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-adhesive tile set in which two tiles are attached to each other by an adhesive applied on the back surface thereof.

[0002]

2. Description of the Related Art In recent years, in the case of a rectangular tile carpet or the like that is adhered to a floorboard or the like, an adhesive is applied to the back surface of the carpet in advance at the factory so that the construction work can be easily performed at the laying site. There is something to store.

In such a tile carpet, two tile carpets are attached to each other by an adhesive applied to the back surface of each tile carpet before shipping from the factory.
A tile carpet set consisting of these two tile carpets is stacked and packaged in a plurality of stages, and is carried into the construction site in that state. And at the construction site,
The tile carpets are separated from each other, and the tile carpets are adhered to each other using the adhesive applied to the back surface of the tile carpets.

Conventionally, as the above tile carpet set, there are those disclosed in, for example, JP-A-61-273315 and JP-A-4-97070.

In the former tile carpet set, the adhesive is arranged so that the adhesive application pattern of the tile carpet on one side and the adhesive application pattern of the tile carpet on the other side are complementary to each other. Is.

The latter tile carpet set is
The back surface of the tile carpet on the other side is bonded to the back surface of the tile carpet on the one side with an adhesive agent interposed therebetween.

[0007]

However, in the former tile carpet set, since the adhesive application patterns on one side and the other side are formed so as to be complementary to each other, the adhesion on the tile carpet on one side is made. When the coating area of the agent is equal to the coating area of the other side, the coating area of the adhesive with respect to the back surface area of the tile carpet is necessarily 50% or less. If the adhesive application area is limited to 50% or less in this way, there is a limit to increase the adhesive application amount, and sufficient adhesive strength cannot be obtained depending on the type and condition of the construction surface. However, the tile carpet cannot be reliably bonded and fixed, and the tile carpet may be displaced or peeled after the construction. Further, in this tile carpet set, the non-adhesive material is arranged in an area other than the adhesive application area on the back surface of the tile carpet, and in addition to the adhesive application work, the non-adhesive material installation work is also performed. There is also a problem that the manufacturing becomes difficult because of the necessity, and the cost increases due to the disposition of the non-adhesive material.

On the other hand, the latter tile carpet set is
Since two tile carpets are bonded together with an adhesive, the tile carpets can be bonded with high adhesive strength by increasing the amount of adhesive provided so as to reliably prevent misalignment during bonding work. Will be done. In particular, if the period from the manufacture of the tile carpet set to the construction (adhesive curing period) is long, or if a strong clamping force is applied during the storage of the tile carpet, the adhesive strength between the tile carpets becomes even higher. This causes a problem that it becomes difficult to separate tile carpets from each other at a construction site.

The present invention solves the above-mentioned problems of the prior art, makes it possible to easily separate the tiles from each other, sufficiently secure the adhesive strength of the tiles to the construction surface, and also to simplify the manufacturing and reduce the cost. It is intended to provide a self-adhesive tile set.

[0010]

In order to achieve the above object, the self-adhesive tile set of the present invention has an adhesive applied to the back surface of each of the two tiles, so that
It's a self-adhesive tile set with the back sides stuck together.
Between the two tiles, the adhesive on one side and the other side
Tile adhesive overlap areas where adhesive overlaps and one side
Tile adhesive and tile adhesive on the other side overlap
There is no adhesive non-polymerized area and both
The adhesive on at least a portion of the periphery between the
The gist is that there is a non-polymerized region.

The structure of the present invention will be described in detail below, taking a case where a tile carpet is used as a tile as an example.

The adhesive applied to the back surface of the tile carpet is a rubber-based adhesive mainly composed of natural rubber, synthetic natural rubber, styrene-butadiene rubber, butyl rubber, etc.
It is possible to use acrylic-based ones such as -ethylhexyl acrylate and n-butyl acrylate, and silicone-based ones such as polydimethylsiloxane rubber. Among these, in view of workability and safety during the coating step, it is preferable to use an aqueous emulsion type.

What shape is the adhesive application pattern?
Although it may be formed on the
Adhesive for tile carpet on one side and tile car on the other side
Adhesive polymerization area where pet adhesive overlaps and one side
Tile carpet adhesive and other side tile carpet
Adhesive non-overlapping areas are mixed
It is necessary to apply an adhesive to the embodiment.

The area of application of the adhesive to the tile carpet is preferably 10% or more and 80% or less, more preferably 30%, of the back surface area of the tile carpet.
It is better to set it to 60% or less in the range of% or more. Application area is 1
If the content is less than 0%, the adhesive strength to the construction surface of the tile carpet cannot be sufficiently secured when the tile carpet is adhered, and the tile carpet may be displaced or peeled off. Further, when the coating area exceeds 80%, in the state where the two tile carpets are stuck together, the adhesive polymerization area becomes large and the adhesive strength becomes unnecessarily high, and the tile carpet during the construction.
There is a risk that it will be difficult to separate them from each other .

The amount of adhesive applied in the adhesive application area is preferably 10 g / m ² or more and 100 g / m ² or less, and more preferably 30 g / m ² or more and 60 g.
/ M ² or less is preferable. Application amount is 10g / m ²
If it is less than the above, the adhesive strength to the construction surface of the tile carpet may not be sufficiently secured when the tile carpet is adhered, and if the coating amount exceeds 100 g / m ² ,
The adhesive strength between the tile carpets becomes unnecessarily high, and it becomes difficult to separate the tile carpets from each other .

The area of the adhesive-polymerized region is preferably 1% or more and 80% or less, and more preferably 10% or more and 40% or less with respect to the back surface area of the tile carpet. If the area of the adhesive-polymerized area is less than 1%, the area of application of the adhesive to the tile carpet will inevitably become small, and the adhesive strength to the work surface of the tile carpet will be sufficient when the adhesive is applied. It may not be possible to secure it. Also the adhesive polymerization area
If the area exceeds 80%, the adhesive strength between the two tile carpets becomes unnecessarily high, which may make it difficult to separate the tile carpets from each other during construction.

In the present invention, both tile carpets are

It is composed of a non-adhesive area.

In the present invention, the tile carpet having the above-mentioned structure
The adhesive application pattern for
Physically, for example, the patterns shown in FIGS. 1 to 3 below are exemplified.

The adhesive application pattern of the tile carpet set (1) shown in FIG.

and a), the cross part adhesive application region of the other side and (3b) are, thus adhesive polymer regions on the intersection region (4) is configured
Is done. In addition, areas other than the adhesive polymerization area (4), such as

The adhesive coating pattern of the tile carpet set (11) shown in FIG. 2 (a) is the back surface (12a) (12) of both tile carpets (11a) (11b).
In b), tile carpets (11a) (11b)

Also, as in the above, the adhesive non-polymerized region (15) is

Further, in the tile carpet set (21) shown in FIG. 3 (a), one side tile carpet (21
The adhesive application pattern of a) is composed of a horizontal striped pattern composed of a plurality of adhesive application regions (23a) extending in a strip shape in the left-right direction toward the paper surface of FIG.
The adhesive application pattern of the other side tile carpet (21b) is composed of a vertical striped pattern composed of a plurality of adhesive application regions (23b) extending vertically in a strip shape. In this case, both tile carpets (21a) (2
By rotating one of the 1b) by 90 degrees, the adhesive application patterns of the two tile carpets (21a) and (21b) have the same shape. In the state where the tile carpets (21a) and (21b) having such a pattern are stuck together, as shown in FIG. 6B, the adhesive application area (23a) on one side and the adhesive application area on the other side are formed. Adhesion where (23b) intersects and both adhesives overlap

Similarly to the above, the adhesive non-polymerized region (25) is a one-sided adhesive.

It is composed of

The adhesive application areas (3a) (3b) (23a) (23b) shown in FIGS. 1 and 3 are each formed in a linear shape, but these areas are non-linear such as wavy lines. Whether it is formed on the tile carpet or on an intermittent line such as a broken line, the adhesive coating pattern has the same shape between both tile carpets. Further, the adhesive application areas (13a) and (13b) shown in FIG. 2 are formed in a circular shape, but even if they are formed in a non-circular shape such as a polygonal shape or an elliptical shape, the patterns have the same shape.

If the adhesive application patterns of both tile carpets are formed in the same shape in this way, the operation of applying the adhesive to each tile carpet can be performed by the same operation. It is possible to easily carry out the operation of applying the adhesive, in other words, the production of the tile carpet set.

Among the adhesive coating patterns shown in FIGS. 1 to 3, the diagonal striped pattern shown in FIG. 1 is composed of linear adhesive coating areas, and two tile carpets are used. Since it is not necessary to rotate one of the tile carpets by 90 degrees at the time of bonding, the adhesive application work and the tile carpet bonding work can be performed most easily.

The tile carpet set of the present invention is manufactured by applying an adhesive to the back surface of each tile carpet and drying it, and then bonding two tile carpets together.

In this production, the screen method can be preferably used when the adhesive is applied to the tile carpet. As the screen used in the screen method, a screen having a size of 29 mesh or more and 250 mesh or less can be used, and preferably a screen of 60 mesh or more and 1
It is better to use one having 40 mesh or less. If less than 29 mesh is used, the amount of adhesive applied may increase, which may make it difficult to separate the tile carpets from each other . Further, if the one having a size of more than 250 mesh is used, the amount of the adhesive applied becomes small, and when the tile carpet is adhered, it is not possible to sufficiently secure the adhesive strength to the construction surface of the tile carpet. There is a case where a positional shift or peeling occurs, which is not preferable.

In the manufacture of carpet sets, 2
When the tile carpets are attached to each other, it is preferable that the adhesive is sufficiently dried before being applied.

That is, the adhesive in the undried state cannot obtain a sufficient adhesive force, and the tile carpet laminating work and the construction work cannot be performed well. If the adhesive construction is performed, when the tile carpet is peeled off from the construction surface, the adhesive remains on the construction surface, and the peeling work cannot be performed well. For this reason, if the tile carpets are pasted together before the adhesive dries to produce a product, it cannot be installed until the adhesive dries, and until the adhesive dries after the carpet set is manufactured. The period (adhesive curing period) becomes longer. Therefore, as described above, after drying the adhesive, if the tile carpets are pasted together into a product, it can be installed immediately after the carpet set is manufactured, so the adhesive curing period becomes unnecessary,
Positive effects can be expected, such as quick response to product demand.

To dry the adhesive, the tile carpet coated with the adhesive is heated in an oven or the like. The drying temperature at this time is 60 ° C to 100 ° C.
C is suitable and the drying time is suitable for 2 to 5 minutes.
If the drying temperature or the drying time does not reach the above specified range, the adhesive will be in a dry state and the above-mentioned problems will occur. If the drying temperature or the drying time exceeds the above-specified range, the product may be deteriorated due to heat or dimensional accuracy may be deteriorated particularly when the product is left for a long time at a high temperature.

<Evaluation>

[Table 2] As shown in Table 2 above, in each of the tile carpet sets of Examples 1 and 2 and Comparative Examples 1 and 2 obtained as described above, two tile carpets were mixed on site.
In order to evaluate the difficulty of the work of separating from each other , the carpets were peeled from each other and the peel strength at that time was measured.

Furthermore, in order to evaluate the difficulty of displacement of the tile carpet on the construction surface at the site, the separated tile carpets were respectively stuck on a PP plate (polypropylene plate), a slate plate and an iron plate, In order to evaluate the slip resistance strength when pulling each tile carpet in the surface direction and the easiness of peeling from the construction surface of the tile carpet at the time of replacement, each tile carpet was peeled from its corner portion to the diagonal line. And the maximum intensity at that time were measured.

As can be seen from the table, in the tile carpet sets of Examples 1 and 2 related to the present invention, the carpets could be peeled from each other with a small force, and the work was easy. Furthermore, the sliding resistance of the carpet on the construction surface (PP plate, slate plate, iron plate) is large, and it is possible to effectively prevent the occurrence of misalignment, and the peeling strength to the construction surface is not so high that the carpet is The peeling work was easy. On the other hand, the tile carpet set of Comparative Example 1 required a large force to peel the carpets from each other, and the peeling work was difficult. Furthermore, the tile carpet set of Comparative Example 2 is
Compared with Example 1, although the same amount of adhesive was applied, the slip resistance of the carpet could not be sufficiently secured, and the positional displacement could not be effectively prevented.
