| Abstract: |
| It introduced the types of epoxy curing agents, including both explicit and potential types. Explicit curing agents mainly included amine, maleic anhydride, synthetic resin and thiols while potential curing agents mainly included dicyandiamide and imidazolium. It discussed in detail the advantages and disadvantages of the curing agents, i.e. amine could be cured at room temperature, maleic anhydride had excellent comprehensive properties, synthetic resin and thiols were resistant to chemicals and corrosion. It also sketched the curing mechanism of polybasic amine, tertiary amine and imidazole curing agents, namely activity atoms attacked the epoxy groups to open the ring and form crosslinked structure, giving the epoxy resin good performances. Finally, it described their application in the field of adhesives and coatings, and forecasted the development trend in the aspects of mechanical properties, thermal properties and environmental protection. |
