Abstract  

Based on a cross-linked polyurethane (CPU) system composed of polyoxypropylene polyol (PPG) and diphenylmethane diisocyanate (MDI), a kind of polyether modified MQ (E-MQ) resin was added to prepare E-MQ reinforced pouring type CPU elastomer. The results show that the E-MQ resin has good compatibility with the CPU, and the prepared E-MQ resin reinforced elastomer has excellent mechanical properties. When the content of E-MQ resin is 8% (E-MQ resin accounts for the total mass fraction of the CPU) the tensile strength of polyurethane elastomer reached to 20.8 MPa, increased by 22.4% comparing to the basic CPU, tear strength is 82 KNm-1, Shore A hardness is 82 degrees.
Key words:  polymer material      polyurethane elastomers      polyether modified MQ resin      tensile strength      thermal resistance
