摘要
介绍了由聚醚N2 2 0、N3 3 0、TDI合成聚氨酯预聚体的实验 ,讨论了聚氨酯预聚体合成工艺及影响因素 ,指出用其制备的聚氨酯防水涂料具有表面光滑、平整、有光泽、流动性好的特点。
The experiment that changes the structure of polyurethane prepolymer to acquire good mutual solubility of prepolymer and asphalt is introduced. At the same time the synthesis technology and influencing factors of polyurethane prepolymer are discussed. Utilizing this technology good polyurethane waterproof paint with smooth surface, planeness and flow ability can be prepared.
