摘要

中插板是用於製鞋工業以支撐腳板，材質需堅挺、耐摺及彈性，屬高單價紙製品，本研究以未漂針葉樹硫酸鹽紙漿、舊牛皮紙袋為原料以濕端添加法製板，依序添加合成乳膠18-20%、樹脂1.0%、白土15%、調配劑1%、凝聚劑1%，熱壓成基重3000g/m^2 之硬板，紙板硬度介於95-98、密度介於0.99-1.06g/cm^3之間，填加2%水性聚　樹脂，可使中插板之耐摺達15次以上不斷裂，相較於加拿大紙板之90°角轉折10次為優，依據本報告建議配方，所研製之中插板生產成本每片(90 x 150 x 0.25 cm)約在NT 40元，適合中小型紙廠生產。

Shank board is used in the shoe industry for supporting the sole of the foot, so medium levels of hardness, folding, and stiffness are required. In this study, shank boards were made using unbleached kraft pulp and old kraft bags with the sequential addition of 18-20% synthetic latex, 1.0% epoxy resin, 15% clay, 1.0% regulator, and 1.0% wet-end coagulant. Then using a hot press, boards of 3000 g/m^2 were produced. Results show that shank board had hardnesses which ranged from 95 to 98 and densities which ranged from 0.99 to 1.06 g/cm^3. To increase the board folding, 2% water-based polyurethane was added to the board, and the 90° angle folding test for more than 15 times was achieved. This result is better than a Canadian product (10 times). The approximate production cost of shank board (90 x 150 x 0.25cm) was NTD 40(~USD 1.153)/piece, which is acceptable for middle-and small-scale paper mills.
