水性聚氨酯阻燃胶黏剂的制备及性能研究
|
摘要
以羟基封端的聚二甲基硅氧烷为改性试剂、己内酰胺为封端剂、羧酸基多元醇做亲水扩链剂,采用阴离子自乳化的方法制备一种聚二甲基硅氧烷改性的环境友好型水性聚氨酯阻燃胶黏剂。通过傅里叶变换红外光谱仪(FT-IR)、万能试验机,极限氧指数测试仪等实验仪器对水性聚氨酯阻燃胶黏剂进行了阻燃性能和力学性能表征。研究结果表明,羟基封端的聚硅氧烷接入分子链结构中,合成的聚氨酯具有良好的阻燃效果,并且得到难燃的胶黏材料,表现出良好的阻燃与力学性能。
With Polydimethylsiloxane as modified reagent and caprolactam as a cappingagent and 2,2-Bis(hydroxymethyl)propionic acid(DMPA) as hydrophilic chain extender,the anion self-emulsifying method is adopted to prepare a kind of an environmental friendly waterborne polyurethane flame retardant adhesive.The waterborne polyurethane flame retardant adhesive was characterized by,fourier transform infared spectrometer(FT-IR),universal testing machine and other experimental instruments.Flame retardance was tested by limiting oxygen index(LOI)tester.The results show that the synthesized polyurethane has good flame retardant effect when hydroxyl terminated polysiloxane is inserted into the molecular chain structure,and the flame retardant adhesive material is obtained,showinggood flame retardant and mechanical properties.
