脆弱纸张加固材料研究

作为一种天然的有机材料,纸张在环境因素的影响下很容易老化。对于脆弱纸张,可通过加固来提高纸张的耐久性。本研究对羟丙基甲基纤维素、有机硅改性丙烯酸脂、有机氟树脂在加固脆弱纸张方面的应用进行了研究。结果表明,羟丙基甲基纤维素(HPMC)能有效改善纸张强度,不改变纸张的外表,不发粘不发黄,耐老化性好,不影响以后的再处理。

Research on consolidation materials for fragile paper

As a natural material,paper deteriorates easily under various environmental conditions.For fragile paper,consolidation materials could be used to improve its durability.Hydroxypropylmethylcellulose (HPMC) fiber,silicone modified acrylic resin and fluorocarbon resin were used as consolidants for fragile paper.The results show that HPMC can improve the mechanical properties of paper without changing its appearance.The treated paper was not sticky and did not yellow.The paper also has very good antiaging properties and potential for retreatment.Compared with other materials,HPMC has many advantages as a consolidant for fragile paper.
