It is about G.

にボ−ドを貼着する必要がある。2. Description of the Related Art When a wall is constructed by a panel, a board, etc. (hereinafter referred to as a board), or when the wall is reformed using the board, a wall base surface or an old wall is used. It is necessary to attach the board to the wall surface.

討されている。For the sticking of this board, a method of using a nail or a screw nail and a method of using various liquid adhesives such as vinyl acetate emulsion type and neoprene type are known, and recently, they have been used. The use of double-sided pressure sensitive adhesive tape is also being considered.

ては、予め釘孔を設けておく必要があり、面倒である。However, the method using nails and screw nails is unsuitable for the construction of the inner wall because of the appearance, and the gypsum board, the asbestos cement board, and the silicic acid are not suitable. Inorganic boards such as calcium boards need to be provided with nail holes in advance, which is troublesome.

時間を必要とし、その間、支え木、仮釘等による仮固定
が必要であり、接着に長時間を必要とするばかりか、仮
固定のために作業がやっかいである。In the method using a liquid adhesive, it takes a considerable amount of time for the adhesive to cure and to exhibit a predetermined adhesive force, and during that time, it is necessary to temporarily fix it with a supporting tree, a temporary nail or the like. Not only does it take a long time for bonding, but the work for temporary fixing is troublesome.

−プ現象により流動し、依然として剥離が発生し易い。Further, when a double-sided pressure-sensitive adhesive tape is used, it is difficult to secure a sufficient contact area with a normal double-sided pressure-sensitive tape because the surface of the board is relatively rough. Delamination is likely to occur due to stress caused by the dead weight of the board and stress caused by board contraction and warpage due to climate change such as temperature and humidity after bonding. On the other hand, if a pressure-sensitive adhesive that is softer than usual is used to secure a sufficient contact area, it may occur due to stress due to the weight of the board or contraction of the board due to climate change after bonding. The adhesive causes the adhesive to flow due to the creep phenomenon, and peeling still tends to occur.

く、上記液状接着剤使用の場合の不利は解消できる。In addition to the liquid adhesive and the pressure-sensitive adhesive, there is a heat-sensitive adhesive as a typical adhesive. In this adhesive, the adhesive is melted and then cooled and solidified to exhibit a predetermined adhesive force. The time required for this is much shorter than the time required for the liquid adhesive to cure and to exhibit a predetermined adhesive force, and the disadvantages of using the liquid adhesive can be eliminated.

溶融にかなりの時間が必要となり、結局、全体の作業時
間が相当に長くなり、作業性も問題となる。However, in order to surface-bond an architectural board by a conventional bonding method using a pressure-sensitive adhesive, the pressure-sensitive adhesive must be heated through the thickness of the board, Since the thickness of the board is thick, it takes a considerable time to melt the pressure-sensitive adhesive, and as a result, the total working time becomes considerably long and workability becomes a problem.

性率を３×１０6以上にすることが望ましい。In this case, it is effective to wet the board and the rough surface of the wall base surface well with the molten adhesive to increase the contact area of the adhesive with the rough surface in order to increase the adhesive strength. .. Further, after the adhesion, it is effective to prevent the room temperature creep due to the stress acting on the adhesive to ensure the stability of the adhesion. Therefore, since the main component of the heat-sensitive adhesive is a thermoplastic polymer, it is a viscoelastic body, and in order to improve the wettability of the molten adhesive and increase the contact area of the adhesive, the heat-sensitive adhesive is used. It is effective to reduce the dynamic shear storage elastic modulus at the time of adhesive melting of the adhesive, and therefore, it is desirable that the dynamic shear storage elastic modulus is 3 × 10 6 dyn / cm 2 or less. Further, in order to prevent room temperature creep, it is effective to increase the dynamic shear storage elastic modulus of the heat-sensitive adhesive at room temperature. Therefore, the dynamic shear storage elastic modulus of the heat-sensitive adhesive at 20 ° C. It is desirable that the rate be 3 × 10 6 or more.

明らかである。In the present invention, since the heat-sensitive adhesive is heated by the heat generated by the high frequency magnetic field of the induction heating material embedded in the heat-sensitive adhesive sheet, the heat-sensitive adhesive can be melted in a short time. Further, since the board is non-magnetic or insulative and is not heated by induction, the molten heat-sensitive adhesive can be cooled quickly. Therefore, the bonding can be performed in a short time, and the next process can be smoothly performed without any trouble. Further, the dynamic shear storage elastic modulus is within a predetermined range so that the wettability of the heat-sensitive adhesive to the surface to be bonded during melt bonding and the prevention of creep after bonding can be sufficiently satisfied. Since the adhesive is used, the contact area between the surface to be adhered and the heat-sensitive adhesive can be sufficiently widened, and further, the creep of the adhesive after adhesion can be well prevented, and sufficient adhesive strength can be guaranteed. . This is clear from the comparison of the measurement results of the shear strength between the following Examples and Comparative Examples.
