| 摘 要： | 介绍了一种纯有机亲水铝箔涂料的制备及研究。对亲水树脂的制备方法进行了改进,并通过实验确定:聚醚预聚体与聚氨酯预聚体投料质量比为1∶1;聚合时聚醚预聚体宜加于釜底;应增大乙烯基磺酸钠单体的加入比例。研究了亲水涂料的调配及涂装工艺,确定亲水树脂与表面活性剂吐温-60的质量比在8~10、涂料的pH值在6~6.5,铝箔经汽油漂洗、碱液浸泡脱脂预处理,成膜温度在250℃时,涂膜持续亲水性能优异。

| Abstract: | The preparation approach of organic hydrophilic coating used for aluminum foil was described.The experimental data showed that the preparation approach of hydrophilic resin was improved when the mass ratio of polyether prepolymer to polyurethane prepolymer was 1∶1,polyether prepolymer was added into reactor for polymerization and ratio of sodium ethylenesulphonate in monomers was increased.The blending and coating technologies were studied.The results showed that when mass ratio of hydrophilic resin to non-ionic surfactant tween-60 was 8~10,pH value of the coating was between 6 and 6.5,aluminum foil was pretreated with benzene degreasing and being soaked in lye,baking temperature was 250 ℃,the coating has excellent long-term hydrophilicity. |
