る。In the case of a cement-based joint filler, water is added to the cement-based powder and kneaded.
Since the joint is sunk into the joint with a trowel, the joint fills the joint, so it protrudes and is applied to the building surface decoration material around the joint, and the surface finishing decoration material attached to the building surface becomes dirty. Therefore, there is a problem that the dirty portion must be pickled and washed away. On the other hand, a synthetic resin-based joint filler is used in the form of a paste having a relatively low viscosity, and after filling the joint filler with the joint, the joint has a low viscosity when the joint is pressed down with a trowel or the like. If the filler fills out and soils the building surface decorations around the joint, it is not easy to remove it.
As shown in FIG. 7, adhesive tapes 5 and 5 ′, which are called curing tapes, are previously adhered to the peripheral edge surfaces of the building surface finishing materials 2 and 2 ′, respectively.
It is necessary to mask the peripheral edge surface of 2 'and then fill the joint filler 30 to perform the operation. FIG. 7 is a schematic cross-sectional view showing a conventional joint filling step of filling joints using a conventional synthetic resin joint filler. FIG. 7A shows a state in which finishing materials 2 and 2 ′ for surface decoration are attached to the building surface 1. Reference numeral 4 denotes a gap between the finishing materials 2 and 2 'for surface decoration, and is a portion where joints are formed. Next, as shown in FIG. 7 (b), adhesive tapes 5, 5 'called curing tapes are attached to the peripheral edge surfaces of the building surface finishing materials 2, 2'. Then, as shown in FIG.
Is filled in the gap 4 using a caulking gun or the like. Next, as shown in FIG. 7D, the surface of the joint filler 30 filled by pressing with a trowel or a spatula is adjusted to have a concave cross section. At this time, since the synthetic resin joint filler 30 has a low viscosity and is sticky, the joint filler 30 protrudes from the joint part to the periphery. The protruding joint filler is indicated by 30 'and 30''. Although not shown, the joint filler 3 shown in FIG.
When filling the gap 4 with 0, the adhesive tape 5,
Often, a part of the coating is applied to the 5 '.
Next, as shown in FIG. 7 (e), the adhesive tapes 5, 5 ′ called curing tapes are applied to the building surface finishing materials 2, 2 ′.
Peel off from the peripheral edge surface of each one and beautiful joints are completed.

When a synthetic resin-based joint filler is used, all four sides of the finishing material for surface decoration are used. It is necessary to attach the adhesive tape to the peripheral edge surface of each piece, and to fill the joint filler and cure, then peel off the attached adhesive tape one by one,
The number of working processes is greatly increased.

In other words, since it is a plastic string like a udon (dried noodle) or clay kneaded with a small amount of water, a conventional liquid joint filler is used. In comparison with, it can be easily filled into the gaps of the building surface finishing material without polluting the surrounding building surface decoration finishing material, and it has plasticity, so from there, an appropriate spatula, iron, or other appropriate jig By pressing and finishing, filling can be buried and filled along the joint shape, and after filling, the joint is cured in the atmosphere, so that a joint having excellent water resistance and durability can be easily formed. Therefore, troublesome steps such as pickling and joint curing (the above-described adhesive tape treatment) can be omitted, and a beautiful joint excellent in water resistance and durability can be easily formed.

のみに限定されるものではないことは明らかである。As the moisture-curable synthetic resin used in the present invention, a resin which does not substantially undergo a curing reaction when stored in a moisture-free state, and which causes a curing reaction by moisture, for example, moisture in the atmosphere. The oxygen-curable synthetic resin used in the present invention may be a resin in which a curing reaction does not substantially occur if stored in the absence of oxygen, and a curing reaction is caused by oxygen, for example, oxygen in the atmosphere. The specific curing mechanism described above is merely an example, and the fact that these resins are not particularly limited to those described above is not limited to a curing reaction that causes a curing reaction due to oxygen or moisture. Since it is clear that any putty-like plastic string containing the synthetic resin before curing of the synthetic resin can be used, it is limited to only those described above. Than not it is clear.

添加してパテ状の可塑物とする事ができる。In order to form a string having a putty-like plasticity by using the above-mentioned synthetic resin before curing the oxygen-curable synthetic resin or the moisture-curable synthetic resin, the synthetic resin has a putty-like plasticity. If it is a liquid, it can be formed into a string, or if it is a liquid, it can be pre-polymerized to a solid state that has putty-like plasticity, and it can be further increased by the absence of oxygen and moisture Those which can prevent the curing from proceeding may be formed into a plastic putty by prepolymerization or the like. However, these resins usually have a viscosity of 250,000 to 30.
Since it is often commercially available in a liquid state of about 000 cps (centipoise), an appropriate solid powder filler can be added to make a putty-like plastic.

(0 × 5.5 mm) is applied to the joint portion of the construction having a joint width of 5 mm, and the same one-component type modified urethane-based moisture-curable synthetic resin “auto-sizing sealant” (used in Example 2) ( Auto Chemical Industry Co., Ltd. only (without adding silica powder) was used as a joint filler. The joint filler was a liquid having a viscosity of about 300,000 cps. After the joint filler was filled, the joint filler was pressed using a joint iron. As a result, the joint filler protruded from the joint and soiled the finishing sheet material for building surface decoration. Dirt could not be removed by wiping, and the surface of the finishing sheet material for building surface decoration was stained widely. Therefore, such a 250,000
Even if a liquid material having a viscosity of about 500,000 cps is used, a clean joint cannot be formed without using a mask material such as the above-described curing tape, and it takes a lot of trouble.

が形成できる目地充填材を提供できる。The joint filler of the present invention is a so-called putty-like plastic cord, and therefore, compared to the case where a conventional liquid joint filler is used, a surface decoration material for surrounding buildings is used. It can be easily filled into the gaps of the building surface decoration material without soiling, and it has plasticity, so it can be pressed along with an appropriate spatula, iron, or other appropriate jig from above, along the joint shape. It can be buried and filled, and is cured in the atmosphere after filling, so that joints with excellent water resistance and durability can be easily formed. Therefore, a troublesome process such as pickling or curing tape treatment can be omitted, and a joint filler capable of easily forming a beautiful joint having excellent water resistance and durability can be provided.
