Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an adhesive for floor tiles in which tiles are not displaced during construction.

(Conventional Technology and Problems) Conventionally, floor tiles have been constructed on a floor base using an adhesive.

At this time, as shown in FIG.
Is formed and the floor tiles 3 and 3n are placed on it. When the foot of the builder 5 is placed on the placed tile and the builder tries to stick the next tile 4 (indicated by a one-dot chain line) in the direction of the arrow a, the tile 3 is tile 3 '(indicated by a broken line). Show)
As shown in the figure, the reference line s of the joint is broken, and it partially overlaps with the tile 3x already pasted on the opposite side. As a result, the joint street is deteriorated and the adhesive of the tile 3 ′ adheres to the tile 4 to attach the tile. Problems such as soiling occurred.

Note that 4n is the tile attachment position in the same direction as the tile 3n. The latex adhesive contains a binder and a tackifier in water, which is a solvent, and has a certain degree of tackiness.

Further, when the solvent-type adhesive was filled with short asbestos fibers, a non-slip effect close to that of the present application was obtained to some extent, but as asbestos is harmful to occupational safety and health, another method was required.

(Means for Solving Problems) The present invention is an invention that solves the above problems, and in an adhesive containing a polymer binder and an organic solvent, a granular weight of 50 to 300 μm, which is not dissolved in the solvent, is included in the composition. The first gist of the present invention is an adhesive for vinyl floor tiles, characterized in that it contains 0.5 to 10% by weight of calcium carbonate in the total amount of the adhesive.

After applying an adhesive containing a polymer binder and an organic solvent, which does not dissolve in the above solvent and has a particle size of 50 to 300 μm, place a vinyl floor tile and before the adhesive gives strength. The second gist is a construction method of a vinyl floor tile, characterized in that a construction person places his / her foot on the tile to perform the floor tile construction.

The present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory view of a construction state of the present invention. When the adhesive 14 is applied to the floor base 1 and the tiles 7 are attached around the floor tile 6 as a center, the tile construction direction is an arrow a, When the floor tiles 8, 9, 10, and 11 are attached to the tiles, the tile construction directions of the builder 5 are arrows b, c, d, and e.

When the builder constructs in the a direction, he puts his foot on the tile 7 and places the tile 12 on the adhesive application portion. Similarly, the tile 13 is placed in the front direction of the tile 8 and the tile 11 'is placed in the same direction as the tile 11. The tiles 11 ', 12, and 13 are indicated by a chain line.

At this time, by using the novel adhesive 14 of the present application, the tile will not be displaced even if the builder rides on the tile on the adhesive that does not yet have strength.

As described above, after the floor tile is placed without displacement, the solvent disappears with the passage of time, and the desired adhesive strength of the tile is obtained.

FIG. 2 is a cross-sectional view of the construction of the present invention, in which the binder 14 and a solvent such as water or an organic solvent are contained in the adhesive 14 on the floor base 1, and the particles 15 having a particle size of 50 to 300 μm are contained. Then, the floor tile 17 is attached and constructed on this.

As a result, the particles 15 in the adhesive 14 create a frictional effect and the tile 17 does not slip.

The novel adhesive in the present invention may be a latex, an emulsion-based water-based adhesive or a solvent-based adhesive, but in the case of a solvent-based adhesive, in particular, the tiles during construction were easily displaced, which is a problem. It is more desirable because it can be solved.

In the present invention, a polyvinyl acetate-based or epoxy-based resin is used as the binder of the solvent-based adhesive. In particular, polyvinyl acetate may be a homopolymer of vinyl acetate or a copolymer thereof with ethylene, acrylic acid ester, methacrylic acid ester or the like, and is preferably added in the state of so-called polyvinyl acetate-methanol paste.

As the solvent for the adhesive, an alcohol such as methanol or ethanol, an organic solvent such as toluene, or acetone is used.

The particles used for the adhesive in the present invention are inorganic particles or organic particles, and these particles are not dissolved in the above solvent.

The particle size of the granules is 50 to 300 μm.

As the above-mentioned granular material, calcium carbonate, clay, silica,
And the like, and powdered pipes of thermosetting resin such as polyester, hard PVC, melamine and epoxy are suitable, and the above-mentioned granules are blended in an amount of 0.5 to 10% by weight based on the total weight of the adhesive.

If the above-mentioned granular material exceeds 10% by weight, the adhesive strength will decrease,
In addition, the open time may be extremely short, and if the amount of the granular material is less than 0.5% by weight, the shift prevention effect is insufficient.

When selecting the organic particle state, combine them so that they will not swell or dissolve in the solvent.

The above-mentioned granules preferably have a corner shape, and it is not desirable that the granules have almost or all round granules.

Further, fillers such as calcium carbonate, talc, clay, etc., which have a particle size of 1 to 5 μm and are smaller than the particle size used in the present invention, which are compounded in the conventional adhesive may be added.

Further, a thixotropy agent, a tackifier, a colorant, a plasticizer and the like may be added as appropriate.

Work Conventionally, especially with solvent-based adhesives, floor tiles were often misaligned during construction and soiled the tiles. According to the present invention, the above-mentioned large particle size particles are contained in the adhesive. As a result, a frictional force is generated between the tile and the floor base material, and the tile is not easily displaced.

Examples will be shown below.

The vinyl acetate solvent-based adhesives of Example 1 and Comparative Example 1 of the compounded compositions shown in Table 1 were prepared.

The adhesives of Example 2 and Comparative Example 2 of the compounded composition shown in Table 2 were prepared.

In the adhesives shown in Table 2, 14 parts of the curing agent was added to 100 parts by weight of the main agent to react.

The adhesive obtained above was tested by the following method to examine the displacement of the floor tile.

The above Example 1 and Comparative Example 1 were applied onto a mortar floor with a comb of an adhesive for vinyl tiles, and after 10 minutes, the vinyl floor tiles were adhered in the same manner as shown in FIG.

The results are shown in Table 4.

Thus, when the adhesive of the present invention was used, the floor tiles could be installed efficiently without shifting.

(Effect of the Invention) According to the present invention, the tile is not contaminated, and the floor material construction is finished beautifully.

Construction efficiency is improved because it is not necessary to perform construction while requiring dirt due to tile displacement.

Since the reference line during floor tile construction does not change, construction efficiency has improved.
