Description

[Detailed Description of the Invention] The present invention allows ceramic tiles to be attached to a base material such as cement concrete, plywood, or resin concrete in a short time with good workability and with high adhesion and extremely excellent impact resistance. It is about the method.

Traditionally, when the base material is cement concrete, the method of pasting this type of ceramic tile to the base material is that the plasterer applies cement alone or mixes it with additives if necessary, as has been done for a long time. The mixture is mixed with bicarbonate of water to make cement mortar, and this is applied to a certain thickness on the base material 3 as shown in Figure 1. A ceramic tile is placed on top of this cement mortar layer 2 and left as it is. When the base material 3 is plywood, iron plate, resin concrete, or some cement concrete, the synthetic resin adhesive 2 such as vinyl acetate or epoxy is used as the base material. Generally, the synthetic resin adhesive layer is applied with a spatula or brush, and then the tile 1 is placed on top of the tile 1 and then left as is to allow the synthetic resin adhesive layer to harden and bond together.

Conventional methods such as Shiriki/Shiko have had major problems in terms of workability, construction time, adhesive strength, and impact resistance.

In other words, when pasting is performed using cement mortar as described above, it requires considerable skill to apply the mortar to a uniform thickness, and if the thickness is uneven, it may be necessary to apply it after the pasting is completed. In this case, the tile painting is not finished smoothly and has unevenness, which is a major drawback in that it is very unsightly in terms of appearance.

In addition, in this case, in order to achieve a smooth finish, pressing only one or a few tiles in the convex portion before the mortar hardens to eliminate unevenness may result in excessive mortar proboscis (between adjacent tiles). This is not possible due to the problem of seepage into the joints.

Therefore, it is necessary to apply mortar to a uniform thickness to the extent possible, but this requires a high level of skill, which is a major problem these days as the number of plasterers is decreasing.

Furthermore, in terms of adhesive strength, even if a mixed material such as latex is added to cement mortar and used, the hardening of the mortar is mainly carried out by the water phase reaction of the cement, so it is inevitable that the adhesive strength will be weak. This is the actual situation.

Therefore, parts of the tiles often peel off during use.

Furthermore, because the adhesive strength is weak, the impact resistance of the tile surface may be affected. If a tool or the like is dropped onto a tile surface, it is unavoidable that the tile in that area will easily crack and become damaged.

In addition, in terms of construction period, cement mortar requires a curing period of at least 7 days, and an additional 4 days for complete hardening.
It takes a considerable number of days, and in this respect too, the conventional pasting method using cement mortarboard has a problem.

Next, if the base material is plywood, steel plate, resin concrete, etc., and a synthetic resin adhesive is used, the synthetic resin used will have a low molecular weight and a low viscosity synthetic resin adhesive will absorb the unevenness of the base material. Since it is impossible to apply the coating as thickly as possible, a high-molecular-weight, high-viscosity product, or a high-viscosity product mixed with an inexpensive filler is generally used.

Therefore, in this case as well, it was a problem because it required considerable skill to coat the base material to a uniform thickness with a spatula, brush, or the like.

The adhesion force of the case is stronger than that of cement mortar, but the use of a high-viscosity product makes it difficult to impregnate the tiles or base material, and therefore the so-called anchoring effect cannot be expected. There was a limit to its strength.

As mentioned above, the conventional method of attaching ceramic tiles to the base material has major problems in terms of workability, construction time, and adhesive strength, and even if expensive ceramic tiles are used, their features cannot be fully utilized. Improvements in this respect have been desired from all quarters.

The inventors of the present invention have conducted various studies to improve this point, and as a result, have discovered a method of attaching tiles that is far superior to conventional methods.

That is, as shown in FIG. 2, in the present invention, a thermosetting resin 5 is applied to a base material 3, a glass fiber base material 4 is placed thereon, and then the thermosetting resin 5 is applied, This is a tile pasting method in which tile 1 is placed on top of the tile.

The thermosetting resin used in the present invention is an epoxy resin, an epoxy acrylate resin, a polyester resin, a phenol resin, etc., and preferably has a viscosity of 0.02 to 10 poise (25
A material with a low viscosity in the temperature range (℃) is suitable.

Furthermore, these thermosetting resins may be used alone or in a mixture of several types, and the curing agent system may be one that is commonly used, and those that are not particularly limited in the present invention may be used. isn't it.

Furthermore, the fibrous material can be appropriately selected from natural fibers, synthetic fibers, glass fiber cloth, paper, non-woven fabrics, etc., but glass fiber materials have good impregnation properties. A glass fiber base material is used in the present invention because it has particularly excellent adhesive strength and durability.

In addition, the method of applying and impregnating the thermosetting resin on the fibrous material may be by applying it with a brush etc. in advance and inserting it between the vitile and the base material, but it is also possible to apply it with a brush etc. and insert it between the base material.
The thermosetting resin is first applied to the surface of the base material,
The method of placing a glass fiber material on top of that, and then placing a tile coated and impregnated with a thermosetting resin on top of that is practical and is therefore adopted in the present invention. .

The advantages of the sticking method of the present invention are as follows.

■) Tiling work does not require the conventional skill and can be easily performed even by an amateur.

2) Compared to the case of using cement mortar, the construction period is greatly shortened and almost no curing period is required.

3) Since the glass fiber base material is used, the adhesive strength of the tiles is greater than that of other fibrous materials, and the tiles hardly peel off during use.

4) Excellent impact resistance of the tile surface due to its high adhesive strength.
Even if an appliance is accidentally dropped on a tile surface, the tile will hardly break.

5) It has excellent water resistance and chemical resistance, and its adhesive strength does not deteriorate much even with changes in waterlogging, so it can withstand long-term use more fully than other fibrous materials.
