Film covering device for constructing self-adhered coiled material with wet method

Abstract

The invention relates to a film covering device for constructing a self-adhered coiled material with a wet method. The film covering device comprises a cooling steel belt, a film covering frame, a left driving roller, a right driving roller, a knurling roller and a main driving roller, wherein the left driving roller and the right driving roller are symmetrically arranged respectively on both sides of the cooling steel belt, the left driving roller and the right driving roller are tangent to the cooling steel belt, an oil applying tank is arranged on the cooling steel belt, an isolating film is coated with covering materials by the oil applying tank, the film covering frame is arranged on one side of the left driving roller, the isolating film is wound on the film covering frame, the knurling roller and the main driving roller are arranged on one side of the right driving roller, and the knurling roller and the main driving roller are tangent. According to the film covering device, an original film covering process is changed, an inherent idea is broken, a great effect is achieved at low cost, under the condition that other aspects are not changed, the appearance of the coiled material is improved by the film covering device, and the wet bonding intensity is increased.

Description

technical field [0001] The invention relates to a film coating device for wet construction self-adhesive coils. Background technique [0002] In recent years, the application range of wet-laid self-adhesive membranes has become wider and wider, especially in rainy areas in the south. For this reason, GB / T23457-2009 "Pre-laid / Wet-laid waterproof membranes" was specially issued, and the market capacity is very large. However, the bonding problem between the wet-laid coil and the cement base has been criticized by people. The wet-laid coil is bonded to the cement slurry, and the quality of the bonding is directly related to the waterproof quality. How to improve the adhesion between the coil and the cement base The connection effect is a major problem in the building waterproofing industry. [0003] The traditional wet-laid coil uses smooth silicone oil-coated PE as the isolation material. The surface area of ​​the smooth PE film is limited, the bonding effect of the coil is n...
