Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is based on a masking material used for embedding a caulking agent, a sealing agent, or other embedding agent embedded between joints of various members, for example, a curing tape. The present invention relates to the improvement of the masking material used in.

[0002]

2. Description of the Related Art Various members, for example, in a wash basin, between a mating joint between a top counter of a wash basin and a makeup mirror, a top counter of a wash basin, and various types mounted in a mounted state on the counter A caulking agent has been filled into the joint joint between the storage cabinet and the joint joint between the top counter and the wash basin to prevent water from leaking from these joint surfaces.
Further, for example, a caulking agent is filled between the installed bathtub and the bathroom wall surface in contact with the bathtub, and hot water or water splashed from the bathtub or condensed water generated on the wall surface travels along the wall surface. It was configured so that it would not leak into the back of the bathtub.

When such a caulking agent or a sealing agent is prepared as a liquid filler containing silicone as a main component, for example, the filler, for example, the discharge port of the tube in which the filler is enclosed, is used for each joining member. It was pressed against the joint edge of, and pushed out so that the filler was embedded in the gap between the joint ends, and this was smoothed with a fingertip, spatula, etc., and the surface was embedded. .

However, in such a method, the joint waterproofing agent pressed between the joint portions of the respective members is present between the joint portions, and the joint makeup becomes irregular in width, so that the joint members are There was a problem that it could not be configured as a clean joint edge.

From this point of view, it is equivalent to the joint width which is required, in this case, planned for each surface of each joining member on both sides of the gap filled with the joint waterproofing agent. It has been attempted that a pair of masking tapes are adhered to each other with a wide width, and a joint waterproofing agent is filled between the joint ends of the joining members prepared for adhering the masking tapes.

With the masking treatment applied, the joint waterproofing agent filled between the joining members is smoothed with a fingertip or a spatula to prepare its surface, and the masking tape prepared for sticking is removed. By peeling it off, it was possible to fill and mold a joint having a straight side edge.

[0007]

Prior to such joint treatment, the masking tape was prepared in advance on both sides of the portion filled with the joint filling agent such as joint waterproofing agent. It has the feature that a joint with straight side edges can be formed without cutting the side edges of the potting agent one by one with a spatula.

However, in such a method, a pair of masking tapes are adhered in parallel along the respective joining edges of the various joining members so that the mutual intervals are made uniform in advance. You need to prepare
The masking tape prepared for sticking is bent,
Alternatively, the joints created by filling the embedding agent using the masking tape prepared for attachment are
There is a problem in that the joint is formed in a curved shape, or the joint is wide on the one hand and narrow on the other hand, so that the joint has a non-uniform joint shape.

The present invention solves the above disadvantages in the conventional joint waterproofing, and the masking tape is configured to easily and surely form the embedding opening portion of the embedding agent having a uniform width. It is an object of the present invention to provide a masking material that can be prepared by adhering to the surfaces of the respective joining members with a predetermined gap.

Claims (6)

[Claims] 1. A pressure-sensitive adhesive sheet-shaped or pressure-sensitive adhesive tape-shaped masking material used for embedding a filling agent such as a caulking agent or a sealing agent applied to the joint portion, wherein the masking material is the joint portion. Is used by adhering to the surfaces of the joining members on both sides of the above, and the portion corresponding to the embedding agent for embedding the joining portion is separable from other masking material portions. Masking material. 2. A masking material in the form of a pressure-sensitive adhesive sheet or a pressure-sensitive adhesive tape, which is used for embedding a filling agent such as a caulking agent or a sealing agent applied to a joint portion, wherein one surface of the masking material is A sheet which is an adhesive surface used by adhering to the surfaces of the joining members on both sides of the joining portion, and the other surface of the masking material is attached by an adhesion weaker than that of the adhesive surface. Strip-like or tape-like release base material, and the adhesive surface on the side not provided with the release base material is adhered over the surfaces of the joining members on both sides of the joint part, and the release base material The masking material, wherein the masking material is peeled off and used, and a portion corresponding to the embedding agent for embedding the bonding portion is separable from other masking material portions. 3. The masking material according to claim 1, wherein the embedding-corresponding portion of the masking material is a plurality of separable pieces. 4. The embedding-corresponding portion of the embedding agent in the masking material is configured to be distinguishable from other masking material portions. Masking material according to item 3. 5. A masking material in the form of a pressure-sensitive adhesive sheet or a pressure-sensitive adhesive tape, which is used for embedding a filling agent such as a caulking agent or a sealing agent applied to a joint, wherein the masking material has two or more masking agents. This stripping base material is provided as a strip, and the masking strip is attached and adhered to a sheet-shaped or tape-shaped stripping base material at an interval corresponding to the embedding-corresponding portion of the embedding agent. The masking material is characterized in that the adhesion to the adhesive is weaker than the adhesion of the adhesive surface to the surfaces of the joining members on both sides of the joining portion. 6. A masking material piece provided with a space corresponding to the embedding-corresponding portion of the embedding agent attached to the release base material, the adhesive material being adhered and adhered. 6. The masking material according to claim 5, further comprising, on opposite sides of the masking material, a separable piece that is separable from the adhesive target surface of the masking material piece, differently from the other part of the masking material piece. .
