【発明の名称】自己修復性遮水用シートの接合方法
Document Type and Number:
Japanese Patent JP2767549
Kind Code:
B2
Abstract:
PURPOSE:To reinforce the bonding force of a self-adhesive tape and to prevent the peel of a bonded part by holding the self-adhesive tape composed of natural vulcanization type rubber between the end parts or side edges of two water barrier sheets reinforced by a fiber sheet to press both sheets and sewing the held part by sewing thread hang a smooth surface. CONSTITUTION:Each of water barrier sheets 10A, 10B is formed by laminating an intermediate sheet 12 and an outer surface sheet 11 to both surfaces of a fiber sheet 13. The end parts of side edge parts of the water barrier sheets 10A, 10B are overlapped each other and a self-adhesive tape 14 is held between them to be pressed and the overlapped part is sewn by sewing thread 16. This sewing thread 16 is composed of a water-absorbable fiber obtained by providing a water absorbing layer composed of a water absorbing material such as a highly water-absorbable resin to the periphery of a synthetic core fiber. The self-adhesive tape 14 is molded from natural vulcanization type rubber prepared by compounding a vulcanizing agent, a self-adhesive or the like with rubber such as EPDM. In this case, two water barrier sheets are temporarily bonded and next sewing becomes easy and the overlapped surfaces are held to a press bonding state and natural vulcanization is advanced and the bonded part is perfectly bonded.
