Embodiment 1
[0052] This embodiment provides a protective material for sealing the outer anticorrosion layer of a pipeline, which includes a protective layer covering the outside of the pipeline and a putty system at both ends of the protective layer. The protective layer includes a resin system and a fiber reinforcement. The resin system includes the following components in mass percent: E51 epoxy resin 55%, polyetheramine D2000 10%, polythiol 30%, 2,4,6-tris(dimethylaminomethyl)phenol accelerator 2 %, polypropylene oxide butyl ether reactive diluent 3%. The fiber reinforcement is 200g / m 2UHMWPE fiber unidirectional cloth. The putty system includes the following components in mass percent: E51 epoxy resin 45%, polyetheramine D2000 15%, polythiol 20%, 2,4,6-tris(dimethylaminomethyl)phenol accelerator 1%, polypropylene oxide butyl ether reactive diluent 3%; silane coupling agent KH550 1%; toughening agent CYH-277 5%; glass microspheres 10%.
