摘　　要：以废旧棉纤维为主要原料,加入一定量废纸,并添加助剂制备一种新型的易降解纸基地膜。研究了棉纤维打浆度、各种助剂和废纸用量对地膜性能的影响。结果表明:制备该新型纸基地膜的最佳工艺条件为85%棉纤维打浆度60°SR,废纸浆5%,水溶性PVA纤维10%,阳离子淀粉1.3%,阳离子壳聚糖0.1%,阳离子聚丙烯酰胺0.7%,羟丙基瓜尔胶0.2%,聚酰胺环氧树脂的0.6%;该条件下制得的新型纸质地膜材料强度性能良好,抗张指数为42.7N·m^2/g,撕裂指数为67.1mN·m^2/g,湿强保留率达49.4%,符合地膜材料的应用要求。A new kind of paper based biodegradable mulch was developed from waste cotton and the optimal preparation conditions for this mulch was also showed as follows：85 % cotton pulp（beating degree 60°SR）, 5 % waste paper pulp, 10% water-soluble PVA fiber and other chemical additives （1. 3% CS,0.1% CCTS,0.7% CPAM,0.2% HPG and 0.6% PAE）. All results showed that the paper based film owned good physical strength （tensile index of 42.7N.m^2/g, tear index of 67. 1mN.m^2/g and wet strength retention of 49.4%） and could be applied as mulch.
