【Abstract】 An excellent adhesive was prepared from bismaleimide (BMI)、epoxy resin(E-51)、4,4-diaminodiphenyl methane(DDM) and liquid rubber.The good thermol stability from BMI,good bonding strength from E-51 and the toughening effect from liquid rubber were retained in the adhesive. The influences of two rubbers on the properties of adhesives (especially high-temperature strength and temperatureimpact strength) were discussed, at the same time, the adhesives were characterized by means of Thermal Analysis(TG/TGA) and Scanning of Electronic Microscopy(SEM).更多还原
