摘要


本試驗的目的在於探討高分子樹脂對含浸紙張性質之影響。試驗中使用的樹脂包括壓克力樹脂、乙烯-乙烯乙酸共聚合樹脂、石油樹脂及聚脲酯樹脂四類10種,探討的紙張性質則有乾、濕抗張強度、撕裂強度、耐摺強度、不透明度、透氣度及上膠度等。試驗結果顯示:樹脂的類別對含浸紙張之性質有決定性的影響。其中對紙張強度影響最大者為壓克力樹脂;石油樹脂則對含浸紙張之不透明度及上膠度有顯著的影響;而乙烯-乙烯乙酸共聚合樹脂在高樹脂率時,會降低紙張之透氣度。

The purpose of this paper is to investigate the properties attainable by impregnation with dispersions of polymers. 10 polymers belonging to four categories are used in this study, they are acrylic resin, EVA resin, petroleum resin and PU resin respectively. The contributions of various saturants to the physical properties of paper such as dry and wet tensiles, tearing resistance, folding endurance, opacity, air permeability and sizing were compared. The results of this study strongly indicate that the categories of polymers play a dominate role in determining physical properties of impregnate-papers. It can be seen that the acrylic resins show the highest tensile and folding improvement and the least tearing retention. Petroleum resin shows the most pronounced effect on the opacity and the sizing of impregnated-papers. EVA resins reduce air permeability at high resin pickups.
