Abstract:
      The principles，methods and research progress of rubber toughening epoxy resin were summarized，and its development direction was prospected.Rubber as a toughening agent could improve the toughness of epoxy resin，and its toughening principles mainly included rubber particle tearing deformation，silver grain-shear band-void and silver grain-anchor theory.The common rubber toughening materials mainly included functionalized liquid rubber，core-shell rubber（CSR） particles and composite rubber toughening agent.The toughening technology of composite rubber toughening agent could to some extent solve the problems of functionalized liquid rubber and CSR particles toughening technology in achieving a balance between processing performance，mechanical properties and thermal stability of epoxy resin.The research on toughening technology of composite rubber toughening agent needed in-depth exploration the mechanism of filler dispersion and synergistic toughening，and develop efficient and stable production processe for toughening epoxy resin to promote its industrialization.
