Abstract: Transplant the coral pieces was an effective method to recover the coral reef habitat.Paper attempted to provide a kind of epoxy adhesive and preparation method, which had a series of characteristics, short reaction time, high gel speed, low toxicity and no pollution to environment.The experiment results indicated that when the two curing agents T31 phenolic amine curing agent and cardanol modified curing agent of ammonium in the same quality, the shear strength and gel time of E44 and T31 curing agent were more suitable, which reached 2.72 MPa and 33 min; After 2 hours of adhesive gelled, shear stress increased significantly, and then improved slowly.The optimal formulation of the self-made under water epoxy resin was determined:Epoxy resin E44 accounted for 57%, phenolic amine curing agent T31 accounted for 33%, coupling agent KH560 accounted for 1.14%, toughening agent accounted for 2.85%, accelerator accounted for 1.65%, fill in total accounted for 2%.In the area of coral reef habitat restoration area with the characteristics which low toxicity and high adhesive strength of epoxy resin, which can provide a theoretical basis and technical support for the restoration of coral reef habitat in the future.
