摘　　要：以IPDI、聚醚胺和乙二氨基乙磺酸钠为主要原料,不加热,只需30min,合成水性聚脲;通过1H核磁共振(1HNMR)、全反射红外光谱(ATR)、乳液透射电镜(TEM)和热重分析(TGA)等测试表征了其结构。1HNMR和ATR谱图显示了水性聚脲的结构,TEM测试显示聚脲在水中均匀分散,胶粒成球形状态,TGA测试表明水性聚脲在300℃左右开始分解。IPDI, polyethenoxyamine and aminoethylamino sulfonate sodium as main materials, through 30 minutes reaction without heating, the water-borne polyurea is prepared. 1H NMR, ATR, TEM and TGA methods are used to characterize the polyurea. The spectra of 1H NMR and ATR are for the structure of the polyurea. TEM shows that the polyurea has been homogeneously dispersed in water and is of spherical particle. And TGA gives that the polyurea starts to decompose at 300℃.
