titleOfInvention | A kind of low viscosity high heat resistant toughening epoxy resin composition |
abstract | The invention discloses a low-viscosity, high-heat-resistance and toughening epoxy resin composition, which is characterized by comprising 30-50% by weight of alicyclic epoxy resin, 30-60% of acid anhydride curing agent, accelerator 0.1-2% and toughening agent 5-20%. The invention has excellent manufacturability and heat resistance, the viscosity before curing is 150-400 mPa·s, and the glass transition temperature after curing reaches 220-260 °C. In addition, the epoxy resin composition also has excellent fracture toughness and low thermal expansion coefficient, and has good application prospects in the fields of composite material manufacturing and microelectronic packaging. |
