Epoxy resin has been widely used in the fields of adhesives,coatings,and composite materials due to its excellent properties.In order to improve the curing rate,and for some heat sensitive components,temperature is an important indicator,it is necessary to lower the curing temperature.Therefore,it is necessary to add curing accelerator.In this article,the research progress and application of curing accelerators for epoxy resin,including tertiary amine and its salt curing accelerators,triphenylphosphine and its salt curing accelerators,substituted urea curing accelerators,imidazole and its salt curing accelerators,boron trifluoride amine complex curing accelerators,etc.were mainly summarized,and the future development direction was pointed out.
