Embodiment 1
[0036] This embodiment provides an electromagnetic welding method for a pre-laid anti-adhesive waterproof membrane, the pre-laid waterproof membrane includes a substrate layer made of polyethylene, and the electromagnetic welding method includes the following steps:
[0037] (1) Fix the pre-welded gasket matched with the pre-laid waterproof membrane to the tunnel arch wall through screws, wherein the gasket is made of a matrix resin layer and embedded on the upper surface of the matrix resin layer Consisting of metal wire; in terms of mass percentage, the raw materials of the matrix resin layer include: polyethylene 10%, polypropylene 15%, ethylene-propylene copolymer 50% and ethylene-octene copolymer 25%, the The matrix resin layer is made by blending, melting and extruding the components in its raw materials;
[0038] Wherein, the middle part of the base resin layer has an inwardly recessed limiting and fixing part, and the middle part of the limiting and fixing part has a s...
Embodiment 2
[0051] This embodiment provides an electromagnetic welding method for pre-laying anti-adhesive waterproof coiled materials, which is basically the same as that of Embodiment 1, the only difference being that in terms of mass percentage, the raw materials of the matrix resin layer include: polyethylene 10%, polyethylene 20% propylene, 40% ethylene-propylene copolymer and 30% ethylene-octene copolymer, the welding time is 1.5s.
[0052] Performance test: The measured bonding strength between the gasket and the pre-paved anti-adhesive waterproof membrane is 5.25N / mm, and the joint shear strength is 12.32N / mm.
Embodiment 3
[0054] This embodiment provides an electromagnetic welding method for pre-laid anti-adhesive waterproof coiled material, which is basically the same as that of Embodiment 1, the only difference being that in terms of mass percentage, the raw materials of the base resin layer include: polyethylene 12%, polyethylene Propylene 18%, ethylene-propylene copolymer 45% and ethylene-octene copolymer 25%, welding time is 1.2s.
[0055] Performance test: The measured bonding strength between the gasket and the pre-paved anti-adhesive waterproof membrane is 4.45N / mm, and the seam shear strength is 11.64N / mm.
