Description

Description: FIELD OF THE INVENTION The present invention relates to a method for manufacturing unit tiles connected by elastic joint material.

2. Description of the Related Art Conventional technology and its problems Conventionally, an inorganic joint material mainly composed of Portland cement was used for filling joints of ceramic tiles. Since the inorganic joint filler is water-based, even if the tile surface is contaminated by the attached joint filler during the joint filling work, it can be easily cleaned by wiping it with a sponge moistened with water.
However, inorganic joint fillers are not suitable as inorganic joint fillers recently because of their poor elasticity and the possibility of cracking or chipping, the fact that they cannot follow the movement of the substrate, causing tile cracks, and their poor waterproofness. Instead, elastic organic jointing materials tend to be used. Although the problems of the above-mentioned inorganic jointing material can be solved by using the organic jointing material, since the organic jointing material is non-aqueous, when the tile surface is soiled with the attached jointing material at the time of joint filling construction, this dirt is removed by the organic solvent. It is necessary to wipe it off and clean it, which is very troublesome. Such problems can be solved by, for example, carefully filling the tile surface so as not to stain the tile surface, or by masking the tile surface, but the former causes a decrease in work efficiency, and the latter causes It is necessary to form a masking for each tile and further remove the tiles, which is not a preferable solution.

The present invention has been made to eliminate such a conventional problem.

MEANS FOR SOLVING THE PROBLEMS The present invention provides a unit tile prepared by adhering an adhesive sheet on the upper surface of a plurality of ceramic tiles arranged with i joint intervals, the adhesive sheet having the lower tile back surface facing upward. Ii) Place the net material on the inverted unit tile so as to cover the entire unit tile, and apply this net material to the entire back surface of each tile of the unit tile in the form of a coating film, and then remove it again. Adhering to the back surface of each tile with a possible paint, and forming a removable masking coating film integral with the above net surface on the entire back surface of each tile, iii. Through the eyes, the organic elastic joint material is released within the joint interval, and if the joint material has adhesiveness to the adhesive sheet, the adhesive sheet side is subjected to release treatment, and if it is not adhesive, release treatment is performed. You And a step of iv to remove each masking coating film from the back surface of each tile along with the peeling of the net material during the uncured state of the filling joint material. , A method of manufacturing unit tiles connected by elastic joint materials.

Examples The manufacturing method of the present invention will be described below with reference to the accompanying drawings.

In the manufacturing method of the present invention, the tile (11) made of ceramics is used, and the ceramic tile (11) has a joint space (12) formed on the base (a) as shown in FIG. And the adhesive sheet (1
Unit tiles (1) are connected by 3).
In the unit tile (1), the shape, size, alignment state and joint size (12) of the tile (11) are substantially the same as those of the known unit tile.

The unit tile (1) is then flipped over on the platform (a),
As shown in FIG. 2, the pressure-sensitive adhesive sheet (2) is placed on the bottom and the back surface of the tile (11) is placed on the table (a).
In the state shown in FIG. 2, the net ground (2) is placed on the unit tile (1), and the removable paint is a thin film from the top of the net ground (2) to the entire back surface of each tile (11). And then dried. By applying and drying this paint, the net (2) is adhered to the back surface of each tile (11), and the back surface of each tile (11) is removably masked with the net (2). A film (3) is formed.

Next, as shown in FIG. 3, a masking coating film (3)
Silicon resin is poured into the joint gap (12) and cured through the eyes of the net portion (2a) opened in (3), and the adhesive sheet (13) surface facing the joint gap (13) is A release layer (4) is formed. The release layer (4) may be formed before the masking coating film (3) is formed.

Next, as shown in FIG. 4, the organic elastic joint material (5) is filled in the joint space (12) through the eyes of the open net portion (2a) as in the case of the silicone resin liquid. ,
After filling, while the joint material (5) is uncured, the net material (2)
The masking coating film (3) is peeled off. In this peeling removal, the masking coating film (3) is integrally bonded to the net material (2). Therefore, when the net material (2) is peeled off, the masking coating film (3) is peeled off as the net material (2) is peeled.
... will also be peeled off from the back surface of the tile (12) one after another, and the masking coating (3) will be used by using the net (2).
... can be removed at once.

After removing the net material (2) and the masking coating film (3) ..., the unit tile (1) is returned to the correct orientation as shown in FIG. 5, and the adhesive sheet (13) and the release layer (4) are removed. The unit tiles (1 ') are obtained by removing the. In this unit tile (1 '), the top surface of the tile (12) was protected by the adhesive sheet (13) and the back surface thereof was protected by the masking coating film (3) during the joint filling work. There is no need for cleaning and wiping. Since the joint material (5) filled in the joint space is placed in a non-adhesive state with the adhesive sheet (13), the surface is not roughened when the adhesive sheet (13) is peeled off, and the surface is smooth. And it will be a beautiful finish. Adhesive sheet (13)
The release layer (4) and the release layer (4) are not necessarily removed at the time of manufacturing the unit tile, and may be removed at the use site.

In the production method of the present invention, the release treatment of the pressure-sensitive adhesive sheet (13) is not always necessary, and may be omitted if, for example, the joint material is not likely to adhere to the pressure-sensitive adhesive sheet (13) with a silicone resin. .

When the release layer (4) is formed as shown in the figure, a unit tile having a deep joint finish as shown in FIG. 6 can be obtained by appropriately selecting the thickness of the layer (4).

This unit tile with a deep joint finish can also be obtained by forming a concave portion (13a) on a pressure-sensitive adhesive sheet (13) using a joint rod or the like, as shown in FIG.

In the present invention, the material of the net (2) is not particularly limited as long as it has adhesiveness to a coating material and appropriate strength, and natural fibers such as cotton, artificial fibers such as rayon, Synthetic fibers such as polyester and other inorganic fibers such as glass fibers may be used.

A suitable thickness of the thread forming the net (2) is about 100 to 500 denier, and an opening of the eyes is preferably about 1 to 10 mm. When the eye opening is 1 mm or less, the passage property of the joint material (4) is deteriorated, and when the eye opening is 10 mm or more, the degree of bonding between the net material (2) and the masking coating film (3) is decreased and the masking coating film ( The peeling and removal of 3) may become unstable, which is not preferable.

As the removable coating material used in the present invention,
Any adhesive may be used as long as it has a weak adhesive force to the surface of the ceramic tile and allows the coating film to be easily peeled off, and those having the following properties are particularly suitable.

(1) Can be easily applied by brushing, spraying, etc.
No special equipment required.

(2) After coating, the coating film formation time is short, and preferably,
A coating film is formed within 1 hour at room temperature.

(3) The coating film has appropriate flexibility so that the peeling work can be easily performed, and has sufficient strength to exceed the adhesive force with the base so as not to damage the coating film during the peeling work.

As a particularly preferable coating material having the above-mentioned properties,
A solvent-type or emulsion-type coating material, which comprises a film-forming polymer as a main component and a solvent or water, and to which a release-imparting material or the like is added if necessary, can be mentioned. Examples of the coating film-forming polymer for such paint include styrene-butadiene-styrene thermoplastic rubber, styrene-isoprene-styrene thermoplastic rubber, ethylene-vinyl acetate polymer, thermoplastic urethane polymer, acrylic ester polymer, Atactic polypropylene etc. can be illustrated.

In the present invention, as the organic elastic joint material, various known materials can be used, for example, polyurethane, polysulfide, silicone rubber, modified silicone,
Those containing liquid chloroprene rubber as a main component are suitable.

Effect According to the production method of the present invention, the finish of the joint portion of the jointing material is beautiful, and the stain on the tile is eliminated, so that a unit tile having a beautiful appearance can be efficiently produced.
