の目的面から均一に流出しない欠点がある。 For example, when using a waterproof joint material, there are two types of water leakage: water leakage from between the joint material and the material to be jointed, and water leakage through the joint material itself.
To prevent water leakage in the former case, it is necessary that the joint material and the material to be jointed are in complete contact with each other, and to prevent water leakage in the latter case, it is necessary that the joint material itself has water leakage resistance. From these points of view, liquid joint fillers are excellent in preventing water leakage. That is, the liquid joint material itself has excellent waterproof properties, excellent adhesion to the material to be jointed, and excellent ability to follow curved surfaces, so it can exhibit excellent water leakage resistance. However, the desired effect is not achieved unless the spaces between the joints are carefully filled, so filling is time-consuming and workability is extremely poor. There are major drawbacks that make it unsuitable. On the other hand, solid joint materials include non-foamed materials, closed-celled foamed materials, and open-celled foamed materials, all of which are easy to handle and have excellent workability, and can be made by the assembly process described above. Although it is suitable for jointing objects, it has the drawback that the adhesion between the joint material and the material to be jointed is significantly inferior to that of liquid joint material, and the compression by the material to be jointed is small in open cell materials. In this case, the joint resistance is poor. As a solution to some of these shortcomings, the
There is number 143143. However, since this method has a groove in the packing body and fills the groove with adhesive, when the material to be jointed is compressed in the form of a string, the adhesive flows out from the cut surface of the string, and the material to be jointed is The disadvantage is that it does not flow out uniformly from the target surface.

Preferably it is 0.20 g/cm 3 . If the density is outside this range, it may become difficult for the foaming reaction type liquid or semi-liquid synthetic resin raw material (hereinafter abbreviated as liquid synthetic resin raw material) to be impregnated into the foam, or it may be difficult to contain it in a sufficient amount. The disadvantages are that it becomes difficult to compress the foam, the force for compressing the foam becomes too large, or it becomes difficult to follow curved surfaces. Further, the hardness of the foam is preferably 20 to 800 g/cm 2 (compression speed 50 mm/min) at 50% compression to ensure good adhesion to the material to be jointed.
