【摘要】 在用环氧树脂E-51和内交联剂TMP共同改性的水性聚氨酯胶粘剂中,适当添加环氧树脂可得到稳定的乳液,且综合性能较好。文中讨论了以共聚方式加入环氧树脂,结合DSC和力学性能等方面的研究,找出了合适的环氧树脂添加量为4．0%-8．0%。用环氧树脂改性的水性聚氨酯涂膜具有硬度高,耐水性好等特点。更多还原

【Abstract】 Which put suitable epoxy resin into the waterborne polyurethane adhesive by E-51 epoxy resin and inner cross-linked agent TMP modified together,can be obtained stable the emulsion and better properties.The article discussed mainly to add the epoxy resin with the copolymerization method,and discovered the appropriate content of the epoxy resin between 4.0%-8.0% in the research of mechanics performance and DSC.There are the properties of high hardness,water resistance and so on for waterborne polyurethane by the modified epoxy resin.更多还原
