【Abstract】 The preparation of the hybrid reinforced rigid polyurethane composite foam was introduced systematically and the preparation process of it was analysed in detail. The structure and properties of the hybrid reinforced rigid polyurethane composite foam was studied and characterized and the application of the rigid PUR foams was introduced. The effect of couple agent on the strengthing performance of the intensifiers and the effect of SiO2 content on water absorption of PUR blends were analysed. Finally, the future development of it was pointed out.更多还原
