Abstract: By semi prepolymer method,a series of polyurethane were synthesized with different isocyanate (TDI,IPDI,HMDI),polyether polyol and BDO.The effect of isocyanate on properties of polyurethane was studied.The results showed that the tensile strength of HMDI type was 7.04MPa that was higher than other and the elongation at break of IPDI type was 600% that was highest in mechanical properties.In performance of water resistance and heat resistance,the best was HMDI type,followed by IPDI type and TDI type.
