Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for decorating tile joints, and more particularly to a method for inexpensively forming tile joints which are excellent in decorativeness and have good durability.

[0002]

2. Description of the Related Art In recent years, along with the improvement of living standards, various building materials have been required to have not only functionality and mechanical properties but also excellent decorative properties. As the interior and exterior tiles, tiles provided with various decorations are provided, and thus, regarding the joints formed between the tiles, decorative joints adapted to the decorativeness of the tiles are desired.

Conventionally, as a method for forming a decorative joint, there is a method in which mica is added to an ordinary cement-based joint material to form a glittering and glittering joint.

[0004]

According to the above method of adding mica, 5% by weight or more of mica having a relatively coarse particle size (about several mm) is added in order to obtain a beautiful tile joint having sufficient brightness. There is a need to. As described above, when a large amount of mica having a coarse particle size is added, the curing property of the joint material is impaired, and the mica is dropped from the formed tile joint surface,
In a remarkable case, a problem occurs in terms of durability such as peeling of joints. Moreover, since a large amount of mica is required, there is a drawback that the cost of the joint material is high.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above conventional problems and to provide a tile joint decoration method capable of inexpensively forming a tile joint excellent in decorativeness and excellent in durability. .

[0006]

According to a first aspect of the present invention, there is provided a tile joint decoration method, wherein after filling a joint material in a joint portion between tiles,
The decorative joint material is characterized in that the decorative joint material is adhered onto the joint material during or after the joint material is semi-cured.

A tile joint decoration method according to claim 2 is the method according to claim 1, wherein the joint material for decoration is cement 100.
It is characterized in that 1 to 1000 parts by weight of mica and 0.1 to 100 parts by weight of polymer (as solid content) are blended with respect to parts by weight.

Hereinafter, the present invention will be described in detail.

In the present invention, first, a normal joint material such as cement-based joint material (hereinafter referred to as "base joint material", and joints formed by this base joint material are referred to as "base joint"). Fill joints between tiles. Then, the filling joint material is adhered onto the base joint material during or after the filling is completed.

In the present invention, as the joint material for decoration,
It is preferable to mix 100 parts by weight of cement with 1 to 1000 parts by weight of mica and 0.1 to 100 parts by weight of polymer (calculated as a solid content). Apply on top of the joint and make it adhere.

The particle size of the mica used for the decorative joint material is not particularly limited, but is usually 10 μm to 1 mm.

As the polymer, ethylene vinyl acetate (EVA) type, vinyl acetate (vinyl acetate) type, vinyl acetate-veova type, vinyl acetate-veova-acrylic type, EVA-vinyl chloride type, styrene-butadiene rubber (SBR). ), Epoxy, acrylic, and other polymers that are usually used for cement materials can be preferably used.

The decorative joint material used in the present invention is particularly preferably a mixture of 10 to 50 parts by weight of mica and 5 to 15 parts by weight of polymer (calculated as solid content) with respect to 100 parts by weight of cement.

As described above, after the tile joint portion is filled with the normal joint material, the decorative joint material is attached to the base joint, thereby significantly reducing the amount of the decorative joint material used. Therefore, the material cost can be reduced and the durability of the joint can be improved.

In the present invention, the filling ratio of the base joint material and the decorative joint material to be filled in the joint is not particularly limited. Generally, filling a large amount of base joint material and a small amount of decorative joint material is advantageous in terms of cost and durability, but decorativeness may be insufficient. Then
When a large amount of the decorative joint material is filled, high decorativeness is obtained, but at the same time, the cost is increased and the durability is reduced. In the usual case, the usage ratio of the base joint material and the decoration joint material is about 1: 0.01 to 0.3 in terms of the ratio of the filling depth of the base joint material and the filling depth of the decoration joint material. Is preferred.

In the present invention, the decorative particles to be mixed with the decorative joint material are not limited to mica, and colored or colorless particles such as glass and metal powder may be used. A decorative effect can be obtained.

[0017]

In the present invention, the base portion of the joint portion is filled with a normal joint material, and the decorative joint material is used only in the surface layer portion. Therefore, in the base portion, the original curing characteristics of the joint material are not impaired. It is possible to form a joint having excellent durability. In the present invention, since the decorative joint material is attached to the base joint, this portion can also have excellent durability.

Further, by using the base joint material as described above, the amount of the expensive decorative joint material used can be reduced and the construction cost can be reduced. The surface layer portion of the formed tile joint is made of a jointing material for decoration, so that it becomes a beautiful joint having desired decorative properties.

According to the tile joint decoration method of the second aspect, it is possible to form a beautiful joint portion having a glittering brilliance by the mica.

[0020]

EXAMPLES The present invention will be described more specifically with reference to Examples and Comparative Examples below.

Example 1 A base joint material prepared by preparing a joint filler for decoration having a composition shown in Table 1, making it into a paste with kneading water, and filling a tile joint portion with a usual cement base joint filler. Then, it was filled with a rubber iron to form a joint for decoration.

The ratio between the filling depth of the base joint material and the filling depth of the decorative joint material is as shown in Table 1, and the decorative joint material was filled after the base joint material was hardened.

After the filling of the decorative joint material, the tile surface was wiped with a water-containing sponge for finishing treatment.

As a result, on the day after the construction, the tile joints were finished beautifully.

Example 2 The same as Example 1 except that the composition of the decorative joint material and the ratio of the filling depth of the base joint material and the filling depth of the decorative joint material were as shown in Table 1. Then, the tile joint was formed, and similarly, the next day after the construction, the tile joint was finished beautifully.

[0026]

[Table 1]

Comparative Example 1 For comparison, when tile joints were formed using only the decorative joint materials in Examples 1 and 2, respectively, tile joints having almost the same decorativeness were obtained. The joint material costs were more than tripled in all cases. Moreover, the joints lacked durability, and some mica was peeled off after long-term use.

[0028]

As described in detail above, according to the tile joint decoration method of the present invention, it is possible to inexpensively form tile joints which are excellent in decorativeness and have good durability.

According to the tile joint decoration method of the second aspect, it is possible to form a beautiful joint portion having a glittering shine by mica.
