摘　　要：珊瑚断枝移植是恢复珊瑚礁生境的有效手段,文章尝试提供一种在水下反应时间短,凝胶速度快,毒性低不污染环境的环氧胶粘剂及其制备方法,可为以后珊瑚礁生境恢复工作提供理论依据及技术支持。实验结果表明:E44和T31固化剂获得剪切强度与凝胶时间较为符合要求,分别达到了2.72 MPa和33min;在此基础上通过加入不同配比偶联剂、促进剂、稀释剂等,抗剪切强度提高至4.24 MPa,凝胶时间缩短至24 min;胶黏剂凝胶2 h后,抗剪切力显著增加,此后缓慢提升。确定了自制的水下环氧树脂最优配方:E44占57%,T31占33%,KH560占1.14%,增韧剂占2.85%,促进剂占1.65%,填料合计占2%。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 2hours 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%,accel-erator 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.
