| 摘 要： | 文章采用硅烷偶联剂(KH550、KH560和KH570)改性纳米SiO2,并利用超声设备将其分散在聚醚二醇中,再加入TDI进行预聚反应,得到-NCO封端的预聚体。利用二乙烯三胺扩链得到A组分,加入固化剂B组分,制得醇溶型纳米SiO2/PU胶黏剂。并对改性后的胶黏剂进行了微观结构分析和性能测试。测试结果表明:经偶联剂改性后的纳米SiO2能够与聚氨酯达到很好的纳米尺度的复合,且掺杂SiO2后的聚氨酯胶黏剂剪切强度和耐水性进一步提高。

| Abstract: | In the paper,the surface of the nanosilica was treated by silicane coupling agent KH550,KH560 and KH570 respectively.Such kinds of silicas were dispersed in polyether glycol by ultrasound equipment.When the TDI was added into prepolymerization reaction,prepolymer that the-NCO groups as the end groups was obtained.Diethylenetriamine as chain extender was added into above solution.A component was obtained.Then hardener part B was added,alcohol-soluble nano-SiO2/polyurethane adhesive was prepared.Microstructure analysis and performance testing for the modified polyurethane adhesives showed that SiO2 which was modified by silicane coupling agent can disperse in with polyurethane on nano-size level.And after adding nanosilica,shear strength and water resistance of the polyurethane adhesive were further improved. |
