[0006] In any of the above conventional examples,
The waterproof sealant is one in which an aqueous emulsion paint is applied to the surface of the joining end of the inorganic substrate, and the waterproof sealant is attached to the surface of the aqueous emulsion paint.
However, since the adhesion between the aqueous emulsion paint and the waterproof sealing material is weak, there is a problem that the waterproof sealing material is easily peeled off.

Here, when the aqueous emulsion paint is applied to the surface of the inorganic substrate, the aqueous emulsion paint is not applied to the surface of the joining end and the surface of the joining end not coated with the aqueous emulsion paint is applied. It is conceivable to attach a waterproof sealing material, but in this case, the joint end of the inorganic substrate and the joint end of another inorganic substrate, which is the joint bottom when joined, are joined. Since the surface is unpainted and the appearance of the joint becomes poor, it is indispensable to apply the aqueous emulsion paint to the surface of the joint end.

In order to solve the above-mentioned problems, a method for treating an end of an inorganic substrate according to the present invention is a method for joining an end of an inorganic substrate to an end of another inorganic substrate. An end 2 is formed, a waterproof sealing material 3 made of a hot-melt resin having water repellency is attached to the surface of the joining end 2, and then the inorganic substrate 1 including the surface of the joining end 2 is attached.
The paint 4 is applied to the surface of the waterproof sealing material 3 having water repellency, and the paint 4 applied to the surface of the waterproof sealing material 3 is repelled to form paint lumps 5 on both sides of the waterproof sealing material 3. Thereafter, the paint 4 is baked. It is a feature. By adopting such a method, the waterproof sealing material 3 is mounted directly on the surface of the inorganic substrate 1 having a porous surface, is mounted so as to bite into the porous surface of the inorganic substrate 1, and the paint 4
The waterproof sealing material 3 is attached more firmly than the case where the waterproof sealing material 3 is attached on the top. Then, a waterproof sealing material 3 made of a hot-melt resin having water repellency is attached to the surface of the joining end 2, and then, a paint 4 is applied to the surface of the inorganic substrate 1 including the surface of the joining end 2. By repelling the paint 4 applied to the surface of the waterproof sealing material 3 having water repellency, the paint mass 5 is formed on both sides of the waterproof sealing material 3 so that both sides of the waterproof sealing material 3 are pressed down by the paint mass 5. As a result, the waterproof sealing material 3 is more securely attached. Moreover, although the paint is repelled on the surface of the waterproof sealing material 3, the paint 4 is applied to the surface of the joining end 2 other than the portion where the waterproof sealing material 3 is mounted. Since the surface of the joining end 2 serving as a joint bottom when the joining end 2 is joined to the end of the other inorganic substrate 1 is coated, even if the joint bottom is visible, the joining portion can be formed. The appearance does not deteriorate.

It is also preferable that the mass of paint 5 is formed on both sides of the waterproof sealing material 3 by flicking, and then the paint 4 is baked to foam and cure the heat-reactive waterproof sealing material 3. By adopting such a method, the waterproof sealing material 3 is mounted directly on the surface of the inorganic substrate 1 having a porous surface, is mounted so as to bite into the porous surface of the inorganic substrate 1, and the waterproof sealing material 3 is provided on the paint 4. The waterproof sealing material 3 is attached more firmly than when the material 3 is attached. Then, a waterproof sealing material 3 made of a hot-melt resin having water repellency is attached to the surface of the joining end 2, and then, a paint 4 is applied to the surface of the inorganic substrate 1 including the surface of the joining end 2. By repelling the paint 4 applied to the surface of the waterproof sealing material 3 having water repellency, the paint mass 5 is formed on both sides of the waterproof sealing material 3 so that both sides of the waterproof sealing material 3 are pressed down by the paint mass 5. As a result, the waterproof sealing material 3 is more securely attached. Moreover, the paint is repelled on the surface of the waterproof sealing material 3,
Since the coating is applied to the surface of the joining end 2 other than the portion where the waterproof sealing material 3 is attached, the joining end 2 of the inorganic substrate 1 and the joined end of the other inorganic substrate 1 are joined. Since the surface of the joining end portion 2 serving as the joint bottom when joining the joints is coated, even if the joint bottom is visible, the appearance of the joint does not deteriorate. Further, by baking the paint 4 last, the waterproof sealing material 3 can be foamed and cured at the same time as the baking of the paint 4.

In addition, a water-repellent waterproofing seal is formed at the end of the inorganic substrate to form a bonding end for bonding with the end of another inorganic substrate, and the surface of the bonding end is foamed and hardened by a thermal reaction. After applying the paint, the paint is applied to the surface of the inorganic substrate including the surface of the joining end, and the paint applied to the surface of the waterproof sealing material having water repellency is repelled. Is formed, and then the paint is baked to foam-harden the heat-reactive waterproof sealing material, so that the waterproof sealing material is directly attached to the surface of the inorganic substrate having a porous surface and cuts into the porous surface of the inorganic substrate. The waterproof sealing material can be attached more firmly than the conventional example in which the waterproof sealing material is mounted on the paint, and the waterproof sealing material can be prevented from peeling off. In addition, a waterproof sealing material made of a hot-melt resin having water repellency is attached to the surface of the joining end portion, and thereafter, a paint is applied to the surface of the inorganic substrate including the surface of the joining end portion, and the repellent is applied. Since the paint applied on the surface of the waterproof sealing material having water is repelled to form paint lumps on both sides of the waterproof sealing material, both sides of the waterproof sealing material are pressed down by the paint lumps, so that the waterproof sealing material is further improved. Is firmly attached,
It can further enhance the adhesion of the waterproof sealing material to prevent peeling, and the paint is repelled on the surface of the waterproof sealing material, but the part of the joining end surface where the waterproof sealing material is attached Since the paint is applied to the parts other than the above, the paint is applied to the surface of the joining end which is the joint bottom when the joining end of the inorganic substrate and the end of the other inorganic substrate are joined. This has the advantage that the appearance of the joint does not deteriorate even if the joint bottom is visible.Furthermore, by baking the paint at the end, the waterproof sealing material is foam-cured at the same time as the paint is baked. And the processing steps can be simplified.
