13 一种新型疏水防潮包装纸板及其性能的研究 1 2 1 夏新干, 董最红 , 张新昌 ( 1. , 214 122; 2. , 311265) : 制备了具有绿色环保特点的聚乳酸( PLA) 溶液涂覆的疏水防潮 板( 原 和箱板 ) , 并研究了其性能 结果表明: 涂覆后, 板的表面更加光滑, 疏水防潮性能也有所提高; 根据所使用聚乳酸溶液的质量浓度的不 同, 板水分吸附率的降低程度也不尽相同, 在 1~ 3 g/ mL 内, 质量浓度越高, 水分吸附率下降得越多, 拉伸强 度也随之增强 : 疏水防潮; 原 ; 箱板 ; 聚乳酸 : T B485. 5; T B484. 1 : A : 1001- 3563( 20 10) 23- 0013- 04 Study on a New Type of Hydrophobic and Moisture Proof Packaging Board and Its Performance 1 2 1 X I A X ing an , D ON G Z uihong , ZH A N G X i nchang ( 1.Jiangnan U niv rsit y, Wuxi 2 14 122, China; 2.
