Abstract

Abstract:

Catalyzed by dibutyl tin dilaurate, a polyether type of epoxy resin E-51 modified waterborne polyurethane adhesive emulsion was prepared using 1,4-butanediol as the small molecule chain extender, dimethylol propionic acid as ahydrophilie chain extender, trimethylolpropane as the crosslinking agent. The performance of modified waterborne polyurethane adhesive emulsion is optimum when the amount of dimethylol propionic acid was 10％, the content of trimethylolpropane and epoxy resin E-51 were 3％ and 4％, respectively. E-51 modified waterborne polyurethane adhesive is provided with good water resistance and high tensile strength.

摘要： 　以1, 4-丁二醇为扩链剂, 二羟甲基丙酸为亲水扩链剂, 三羟甲基丙烷为交联剂, 在二月桂酸二丁基
锡的催化作用下, 用E -51 将聚氨酯改性, 得到一种新型的聚醚型的改性水性聚氨酯胶粘剂乳液。当二羟甲基丙酸
质量分数为10%, 三羟甲基丙烷质量分数为3 %, 环氧树脂E-51 质量分数为4%时, 改性产物的性能最佳。以环氧
树脂E-51 改性后的水性聚氨酯胶粘剂具有耐水性好、拉伸强度高等特点。
