Abstract

PURPOSE:To inexpensively form joint-contg. patterns having substantial waterproofness on the surface of a structure by sticking a waterproof self-adhesive agent layer to the surface of the structure, providing a masking material and further chief material paint thereon and stripping the masking material prior to the curing of the paint. CONSTITUTION:A chloroprene rubber adhesive agent is roller-coated on the surface of the structure 10 and after the solvent thereof dries, the surface of a sheet from which release paper is stripped is stuck thereto. The paint 2 such as styrene/acryl copolymer emulsion is sprayed onto the self-adhesive material 11 from above the masking material 12. The masking material 12 is stripped from the self-adhesive agent layer 11 before the paint 2 cures to obtain the joint-contg. patterns. The joint-contg. patterns having the substantial waterproofness over a long period of time are thus easily and inexpensively formed on the surface of the structure.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for forming a joint pattern on the surface of a structure and a sheet for forming the pattern.

Conventional techniques and their problems Conventionally, as a method for forming a joint pattern on the surface of a structure, for example, as disclosed in Japanese Patent Application Laid-open No. 49-8025, a first coating film is formed on the surface of the structure. , attaching a strip onto the coating film, and forming a second coating film over the strip;
Method for peeling off the strip after that, JP-A-57-25958
As disclosed in the issue, a sheet with double-sided adhesive tape corrected in a joint pattern on a mount is prepared in advance, and the tape is applied to the surface of the structure coated with the under-sprayed material, and then the mount is peeled off. There is a method in which the material is sprayed onto the surface of the structure from the tape and then the tape is peeled off.

However, the patterned layer obtained by these methods does not have sufficient waterproofness, and when a crack occurs in a structure, the patterned layer consisting only of a paint film cannot cope with the occurrence of cracks, and cracks occur. This tendency is stronger in joints where the paint film is thinner than in other areas, and there is a big problem with waterproofing. It was unsuitable as a decorative finish for areas that come into contact with water, such as surfaces.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for forming a joint pattern with sufficient waterproof properties on the surface of a structure at a low cost, and a sheet for forming the pattern easily and efficiently.

Means for Solving the Problems The above-mentioned objects of the present invention include a step of adhering a waterproof adhesive layer to the surface of a structure, a step of providing a masking agent on the surface of the waterproof adhesive layer, and a step of applying a masking agent to the surface of the waterproof adhesive layer. A grout pattern on the surface of a structure characterized by a step of applying a base paint to the surface of the adhesive layer from above, and a step of peeling off the masking agent from the adhesive layer before the base paint is cured. and a flexible waterproof adhesive layer, a flexible joint-equivalent masking material provided on the surface of the adhesive layer, and a release paper attached to the back surface of the adhesive layer. This is achieved by using a sheet for forming jointed IG4 walls on the surface of a structure.

The waterproof adhesive layer used in the present invention may be made of only a waterproof adhesive or a waterproof adhesive and a suitable reinforcing material. In any case, it is desirable that the waterproof adhesive has good waterproof properties, has good adhesion to the surface of the structure, and has good adhesion to the main paint, and natural rubber or Synthetic com-based adhesives (such as those containing natural rubber, polybutene and tackifying resin as main components, butyl rubber and polybutene as main components, etc.), binder, filler, etc. as necessary.
An example is one in which stabilizers and color pigments are added in equal parts.

When the adhesive layer includes the reinforcing material, the reinforcing material is
This reinforcement material is used to increase the tensile strength of the adhesive layer and to prevent the layer from elongating and tearing during the adhesive plate, dripping, flowing, etc. Examples include base fabrics (woven fabrics or non-woven fabrics) or nets with low elasticity made of certain natural or synthetic fibers. Such reinforcing materials, which are placed by being buried in the adhesive or press-fitted onto the surface of the adhesive, may interfere with the adhesion of the adhesive layer to the surface of the 114 structure, or may damage the surface of the adhesive layer. It is important that this does not interfere with the adhesion of the main paint to the surface.

The masking material used in the present invention may be any material as long as it is not easily damaged by the main paint and can be peeled off before the main paint hardens, and may be made of various materials such as paper, synthetic resin, and foam. obtained from the material. The surface of the masking material to which the adhesive layer is attached may be treated with a release agent, if necessary. Note that the joint pattern in the present invention includes tile joints, brick joints, and various other patterns.

For example, an acrylonitrile emulsion, a butyl acrylate emulsion, or a styrene-acrylic copolymer emulsion and an aggregate (e.g., porcelain powder) are blended into the main paint, and if necessary, a filler (e.g., calcium carbonate) is added thereto, Furthermore, if necessary, add a small amount of dispersant, thickener,
An example is a coating 1 containing an antifoaming agent or the like. The aggregate may also serve as a colorant, and the amount thereof can be approximately equal to the emulsion in terms of weight ratio.

In the method of the present invention, after the masking material is peeled off from the adhesive layer before the main paint hardens, the main paint and the exposed surface of the adhesive layer are appropriately finished. There is no problem.

This finishing treatment includes top-coating the entire surface with clear paint, coloring the entire surface with an appropriate colored paint and then top-coating it, or applying a pattern with a roller, etc. only to the surface of the main paint, or coloring the surface and then top-coating the entire surface. Examples of treatments include coating the entire surface with a suitable colored paint, applying a pattern with a roller or the like only to the surface of the main paint, or coloring and then top-coating the entire surface.

In the method of the present invention, either the step of attaching the adhesive layer to the surface of the structure or the step of providing the masking material on the surface of the adhesive layer may be preceded. If the latter step of providing a masking material precedes the latter step, then the step is to remove the adhesive layer and masking material! It may be carried out in advance at the manufacturing site. It is desirable to be able to peel off the masking material and reapply it when the masking material is in a bad position with respect to the adhesive layer attached to the surface of the structure.To do this, the masking material should be treated with a release agent in advance. It is desirable to apply

When applying the pressure-sensitive adhesive layer to the surface of a structure in J3 according to the method of the present invention, the surface of the structure can be subjected to a brimer treatment in advance, if necessary. Water-resistant adhesives are preferable for the brimer, and so-called co-glues, which are prepared by dissolving butyl rubber, adhesive resin, fillers, anti-aging agents, etc. in a solvent, are preferable.
Other examples include Ri['] Robrere adhesive, acrylic emulsion contact type adhesive, and the like. Also, when applying the base paint to the adhesive layer, the surface of the adhesive layer may be subjected to a brimer treatment in advance, if necessary. Water-resistant adhesives such as these are preferred, such as acrylic emulsion contact type adhesives.
