Abstract
DISCLOSED IS A PREPARATION METHOD OF RIGID POLYURETHANE. A CHAIN EXTENDER IS HEATED AT 100-110°C TO MELT, AND IS MIXED AND REACTS WITH A PREPOLYMER WITH THE MASS RATIO BEING 20-29.4:100. THE MIXING TEMPERATURE IS 60-75°C. THE PRODUCE IS POURED INTO A MOLD, AND UNDERGOES VULCANIZATION AT 100-110°C FOR 30 MINUTES BEFORE DE-MOLDING. FINALLY, THE PRODUCE UNDERGOES VULCANIZATION AT 90-110°C FOR 8-10 HOURS TO OBTAIN RIGID POLYURETHANE. IN WEIGHT PERCENT, DIISOCYANATE (24.5-50%) AND POLYMER POLYOL (50-75.5%) REACT AT 80-85°C FOR 2-3 HOURS, SO AS TO OBTAIN THE PREPOLYMER WITH ISOCYANATE ACCOUNTS FOR 7-10%. THE CHAIN EXTENDER IS AN AMINE-BASED CHAIN EXTENDER. THEREFORE, THE PROBLEM OF DECREASED PRODUCT HARDNESS INCURRED BY INTERMOLECULAR HYDROGEN BOND BREAKAGE AND DECREASED INTERMOLECULAR FORCES WHEN THE RIGID POLYURETHANE IS AT HIGH TEMPERATURE IS SOLVED, AND RIGID POLYURETHANE WITH THE SHORE HARDNESS GREATER THAN D60 AT ROOM TEMPERATURE AND THE SHORE HARDNESS STILL GREATER THAN D50 AT 80°C IS OBTAINED.
