Summary:
polyurethane prepolymer was synthesized from toluene diisocyanate, polyether glycol, 2, 2-dimethylol propionic acid, etc., and crosslinked waterborne polyurethane was prepared by 3-aminopropyl triethoxysilane (KH550) sealing and emulsification. The properties of the waterborne polyurethane were tested. The results show that KH550 can significantly improve the water resistance and hardness of waterborne polyurethane. When the mass fraction of KH550 is 7.5%, the comprehensive performance of waterborne polyurethane is better, and the hardness is 2H.

Summary:
KH-550 modified polyurethane polymer was synthesized with polyether glycol (N210) and isophorone diisocyanate (IPDI) as main raw materials and 3-aminopropyltriethoxysilane (KH-550) as silicone modifier. The effect of KH-550 dosage on the mechanical properties of modified polyurethane elastomer was investigated, and the structure of KH-550 modified polyurethane prepolymer was characterized by Fourier transform infrared spectroscopy. The results show that the modified waterborne polyurethane dispersion has good stability, the feel of the film is soft, the water absorption is reduced, and the mechanical properties are significantly improved.
