Embodiment Construction
[0010] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:
[0011] Such as figure 1 As shown, the pipeline repair sheet of the present invention has a layered structure, the first layer is a polyolefin substrate layer 1, and a hot melt adhesive layer 2 is arranged on the polyolefin substrate layer 1. The polyolefin substrate layer 1 is a high-density polyolefin subjected to cross-linking radiation. The polyolefin substrate layer 1 is coated on two layers of polyethylene anticorrosion pipes. The hot melt adhesive layer 2 has airtightness.
