Immediately after attaching the weight, the test piece was gently inverted so that the vinyl chloride-based waterproof sheet could be pulled by its own weight of 10 g.
The time until the vinyl chloride-based waterproof sheet peeled from the flexible board was 30 seconds or more (o), and the case shorter than 30 seconds was (x).

接着強度確認
23℃雰囲気下にて2液を十分に混合し、くし型の塗布治具を用い、フレキシブルボード(70mm×150mm)に塗布した。15分間静置し、塩化ビニル系防水シート(25mm×200mm)を張り付けシート上を5kgローラーにて2往復しシートを圧着した。
23℃雰囲気下にて48時間静置養生後、引張速度200mm/minにて90°剥離試験を行った。20N/25mm以上を(○)、20N/25mmに満たない場合を(×)とした。
初期固着力確認、接着強度確認結果を表3、表4に示す。
Adhesive strength check The two solutions were mixed sufficiently in a 23 ° C. atmosphere, and applied to a flexible board (70 mm × 150 mm) using a comb-type application jig. The sheet was allowed to stand for 15 minutes, a polyvinyl chloride-based waterproof sheet (25 mm × 200 mm) was attached, the sheet was reciprocated twice by a 5 kg roller, and the sheet was crimped.
After standing for 24 hours in a 23 ° C. atmosphere, a 90 ° peel test was conducted at a tensile speed of 200 mm / min. 20 N / 25 mm or more is (○), and the case of less than 20 N / 25 mm is (X).
Tables 3 and 4 show the results of the initial adhesion strength check and the adhesion strength check.
