Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a tile adhesive used for attaching tiles to the walls and floors of buildings, particularly for attaching tiles to walls such as bathrooms and kitchens. The present invention relates to adhesives for ceramic tiles.

[Prior Art] There are various types of tiles such as vinyl tiles, wood tiles, ceramic tiles, etc., and the appropriate one is selected and used depending on the conditions of the position where the tiles are to be laid. In any case, an adhesive called tile bond is applied to a building base such as veneer, asbestos board, or mortar, and the tiles are crimped onto the adhesive. In particular, when installing tiles on the exterior walls of buildings, instead of joining them with a single adhesive, mix a suitable tile adhesive with mortar and apply this mixture to the base. Tiles are crimped onto the top of the tile.

[Problems to be Solved by the Invention] In any case, the above-mentioned tile adhesives have high fluidity and tend to "sag", so when installing tiles on a wall surface, they are slightly large and heavy. Large tiles are difficult to hold onto the joint surface and tend to fall down gradually.

In other words, ceramic tiles (including ceramic, porcelain, and semi-porcelain) are usually installed on the floors and walls of bathrooms, kitchens, etc., but especially when installing these ceramic tiles on the walls, , 200 square square or more, it is difficult to hold it in the intended position on the wall base due to the fluidity of the adhesive, and it tends to fall easily.

However, to ensure accurate tile positioning,
At present, during the crimping process of tiles, it is recommended to use means to hold the tile in place, such as by inserting a suitable piece of wood between the joints, or to wait some time after applying the adhesive until its fluidity has decreased slightly. Methods such as crimping the tiles from the ground are used.

By the way, as shown in FIGS. 1 and 2, some of the ceramic tiles 1 and the like described above are equipped with a large number of joint grooves 2, 2, etc., which are wide inside, on the back surface, which is the adhesive surface. be. These bonding grooves 2.2... are formed by a part of the adhesive applied on the substrate entering and solidifying when the ceramic tile 1 etc. is crimped. The purpose is to ensure the bonding of the tile to the base by making the adhesive in the bonding grooves 2.2 and 2.2 continuous.

However, as mentioned above, conventional tile adhesives have high fluidity, so when installing tiles on a wall, it is necessary to apply the adhesive as thinly as possible, for example, after applying it, there are many small grooves at the tip. The adhesive 5 is scraped off using something like a spatula with a 30-degree diameter formed thereon, leaving the adhesive 5 only in the plurality of strips, thereby reducing the fluidity in a short time and preventing the drop phenomenon when the tiles are crimped. Therefore, most of the adhesive 5 is applied to the bonding grooves 2, 2, etc. formed on the back surface of the ceramic tile 1, etc.
The reality is that the above-mentioned purpose of strengthening adhesion is not utilized at all because there is no intrusion. Furthermore, since the adhesive 5 adheres only to the remaining filamentous lines as described above, a problem arises in that the bonding area is small.

The present invention aims to solve these problems in adhesives.

[Means for Solving the Problems] The gist of the configuration of the present invention is as follows: Ivy and foamed asbestos calcium carbonate are added to a single tile adhesive in a weight ratio of 100:0.025 to 0.075: This is a tile adhesive mixed with 0.4 NO.9.

As the above-mentioned single adhesive for tiles, all the single adhesives for tiles that are currently being reprinted can be used. There are many others, including D-Pound (Hodaiken's trademark), Jobat (■Unique's trademark), and as mentioned above, any of them can be used as a target. Note that adhesives for exterior wall tiles can also be used in the same manner. However, this case is different from the case for interior tiles in that it is mixed with mortar as described above.

As the ivy, hemp fibers cut into lengths of about 10+sm to 20mm or chemical #a male can be used. Ivy made of chemical fibers has the advantage that it is stronger than one made of hemp, and it is easier to obtain one that does not contain impurities. Moreover, of course, there is nothing wrong with ivy consisting of chemical male and male. As an example of ivy made of chemical fiber, Pearl Wool (trademark of Shirai Asasuji Factory) is suitable.

The above-mentioned foamed asbestos calcium carbonate is suitable as a single substance, but it may also be made with this as its main material and added with some adhesive, thickener, and cellulose. Examples include mild sand ( (trademark of Hayashi Cement Industry).

It is preferable to mix ivy and foamed asbestos calcium carbonate into the adhesive by thoroughly stirring and kneading.

The above weight ratio is effective as long as it is within the above range, but in particular: Adhesive alone: Ivy: Foamed asbestos calcium carbonate = 100:
A ratio of 0.04:0.6 provides the best tile adhesive.

[Function] Since the tile adhesive of the present invention is configured as described above, when it is applied to a base and tiles are laid, even if it is a wall base, and 200
Even when a ceramic tile of mm square or more is stretched on the wall base, the adhesive can sufficiently hold the tile in the pressed position.

For example, when the ceramic tile with a plurality of bonding grooves on the back side is to be installed on the wall of a bathroom or kitchen, the adhesive is applied to the wall base a little thicker than the conventional one, The adhesive of this invention, which is used to bond the ceramic tiles by pressure, has low fluidity and "
Ceramic tiles crimped as described above will not slide down, even if they are relatively heavy and are larger than 200 mm square. There is no need to clamp a corresponding piece of wood or provide other position holding means. Therefore, the tile installation work can be done quickly.

Furthermore, unlike conventional adhesives, as mentioned above, it can be applied to the required thickness, so that when the tiles are pressed together, the adhesive can fully penetrate into the bonding grooves on the back side of the ceramic tile. It is thus also possible to ensure a sufficiently strong tile bond after the adhesive has hardened.

By the way, when the above-described tile adhesive for exterior walls is prepared, it is used by mixing it with mortar, as described above. Other effects are similar to those of the interior tile adhesive described above.

[Example] An embodiment of the present invention will be described below.

20 in a can, 0 in a single D pound (trademark of X Dalian)
．． 008, pearl wool (trademark of Shirai Asasuji Factory) and 0.12 kg of foamed mild sand (trademark of Hayashi Cement Industry) were mixed.

As mentioned above, the D-pound is an adhesive for tiles.

As mentioned above, the pearl wool has a thickness of 10 to 20 mm.
It is made of white chemical fiber cut into lengths.

The above-mentioned mild sand is mainly composed of foamed asbestos calcium carbonate, to which some adhesives, thickeners, and cellulose are added.

A tile adhesive was produced by mixing and stirring the above elements as described above.

Using this tile adhesive, a 200+ square meter ceramic tile l as shown in FIG. 1 was attached to a bathroom wall.

The ceramic tile 1 has a plurality of coupling grooves 2 on the back surface.
It is equipped with 2...

First, the tile adhesive 4 is applied slightly thickly onto the wall base 3, and the ceramic tile I is pressed onto the wall base 3. Then, as shown in FIG. 1, the tile adhesive 4 is bonded to the bond N2.2 of the ceramic tile l.
will be fully incorporated. Even if the tile adhesive 4 is applied a little thicker in this manner, the adhesive 4 does not "sag" and the ceramic tile 1
Ensure that the crimping position is maintained.

Therefore, when the ceramic tile 1 is crimped, it is no longer necessary to attach a means for holding the position of the tile, which was necessary in the past. Since unnecessary work is eliminated, the tile installation work can proceed quickly.

Furthermore, the tile adhesive 4 was applied thickly, and the tile adhesive 4 was able to be sufficiently spread over the bonding grooves 2, 2... on the back side of the ceramic tile l, so that the ceramic after solidifying The connection between the tile 1 and the wall base 3 is ensured.

[Effects of the Invention] According to the tile adhesive of the present invention, there is no "sagging" immediately after application, so even when installing a considerably heavy tile in a position where it is easy to move, such as on a wall base. Also, the adhesive position can be maintained almost reliably. Therefore, there is no need to take any special means to hold the crimped tiles in place, and the tile installation work can be carried out efficiently.
