An electromagnetic welding method for pre-laid anti-adhesive waterproof membrane

Abstract

The invention discloses an electromagnetic welding method for pre-laid anti-adhesive waterproof coiled material. The pre-laid waterproof coiled material includes a base material layer made of polyethylene, including: 1) matching the pre-welded waterproof coiled material with the pre-paved waterproof coiled material The gasket is fixed on the substrate, and the gasket is composed of a matrix resin layer and a metal wire inlaid on the upper surface of the matrix resin layer; in terms of mass percentage, the raw materials of the matrix resin layer include: polyethylene 5-30%, polyethylene Propylene 5-30%, ethylene-propylene copolymer 20-50% and ethylene-octene copolymer 20-50%; 2) Lay the pre-laid waterproof membrane on the substrate, so that the pre-laid waterproof membrane and the gasket are attached Then align the electromagnetic welding torch and press it on the pre-laid waterproof membrane at the position of the gasket, and start welding. The invention can quickly fix the pre-laid waterproof membrane on the substrate, and the operation is simple and controllable. It has good performance and firm welding, and also avoids the problem of later leakage caused by nailing and other fixing methods in the prior art.

Description

technical field [0001] The invention belongs to the field of pre-paved anti-adhesive waterproof coiled material, and in particular relates to an electromagnetic welding method for pre-paved anti-adhesive waterproof coiled material. Background technique [0002] The existing pre-paved anti-adhesive coil facade fixing method is to nail directly on the surface of the coil, but the steel nail penetrates the main body of the coil, which will cause a great leakage hidden danger to the waterproof layer in the later stage, which is not conducive to high requirements for waterproofing construction environment. After further improvement of the construction process, the operator has to heat the contact surface between the back of the pre-laid anti-adhesive coil and the ordinary PE or PP gasket through hand-held hot air welding. However, the actual operation is difficult, and the plasticity temperature range is narrow, which has extremely high requirements on the fluctuation range of t...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provide an electromagnetic welding method for pre-laid anti-adhesive waterproof coiled material, which can quickly fix the pre-applied waterproof coiled material on the substrate, and is easy to operate and can be used. It has good controllability, and the welding is firm, which does not affect the appearance. At the same time, it also avoids the problem of later leakage caused by nailing and other methods in the prior art.
