Definitions
- the invention relates to the field of PVC waterproofing membranes, especially for the roof construction.
- PVC waterproofing membranes have been known for some time. They have also been used for a long time for sealing roofs and roof structures. Traditionally, the tracks are laid on the roof and welded together. For attaching such tracks are so far primarily mechanical anchors, z. As nails, used. Of course, the guarantee of tightness is a big problem.
- PVC waterproofing membranes contain a large amount of plasticizer to ensure long-term flexibility of the waterproofing membrane.
- the object of the present invention is therefore to provide a PVC sealing membrane or a method of sealing, which at least greatly reduces, if not prevents, the plasticizer absorption of the adhesive from the PVC film.
- a waterproofing membrane according to claim 1 is able to achieve this object.
- this film easily allows a long-cherished desire to namely to realize a full-surface and long-term bonding of a PVC sheet with a substrate, in particular a roof or a roof structure, and thus to achieve optimum sealing.
- a layer of PE has, for its part, an efficient barrier action against plasticizers, as are commonly used in PVC, especially plasticized PVC.
- the sealing sheets disclosed in this document are easy to produce, can be stored and transported for extended periods of time, and can be laid and bonded in an extremely simple manner.
- no mechanical fastening means, such as nails or the like, are required for laying and fixing. This reduces the susceptibility of slides to injuries. As a result, sources of leakage are massively reduced.
- the present invention relates in a first aspect to a sealing sheet.
- This waterproofing membrane has the following layer structure:
- the layers are arranged in the order a), b), c) and d).
- flexible film is understood to mean, in particular, flexible sheet-like plastics in a thickness of from 0.05 ⁇ m to 5 mm thick, which can be rolled up.Thus, in addition to films in the strict sense, thicknesses of less than 1 mm, and although, preferably, sealing sheets, as typically used for sealing tunnels, roofs or swimming pools in a thickness of typically 1 to 3 mm, in special cases even in a thickness of up to 5 mm, are understood , Calendering or extrusion and are typically commercially available in rolls. or produced locally. They can be single-layered or multi-layered.
- films may also contain other additives and processing agents, such as fillers, UV and heat stabilizers, plasticizers, lubricants, biocides, flame retardants, antioxidants, pigments, such as titanium dioxide or carbon black, and dyes.
- additives and processing agents such as fillers, UV and heat stabilizers, plasticizers, lubricants, biocides, flame retardants, antioxidants, pigments, such as titanium dioxide or carbon black, and dyes.

The PET film advantageously has little, preferably no plasticizer.
- the PET film has an excellent plasticizer barrier effect.
- an aluminum layer in addition to the PET film, an aluminum layer can also be used, in such a way that between the layer b) of the first adhesive (K1) and the layer c) of the polyethylene terephthalate film (F2) a layer b ') of aluminum (F3), in particular in the form of an aluminum vaporization, is arranged.
- the layer thickness of the aluminum layer is preferably thinner than 20 micrometers, preferably between 1 and 15 micrometers.
- the thickness of the PET film (F2) can be reduced. It is particularly suitable in these cases if the thickness of the PET film (F2) is at least 0.5 micrometers, in particular between 1 micrometers and 50 micrometers.
- the aluminum layer may be applied to the PET film via vacuum coating techniques or by fusing or melting the PET film onto an aluminum foil.
- the PVC film (F1) is in contact with a first adhesive (K1).
- This adhesive produces a good bond between the PVC film and the polyethylene terephthalate film (F2).
- Adhesives based on (meth) acrylates have proven to be such a first adhesive in particular. It has proved to be particularly advantageous if this adhesive can be activated by heat.
- the first adhesive wen preferably no, contains plasticizer.
- the adhesive effect of the adhesive should not be adversely affected by plasticizers from the contacting PVC film.
- the PVC film or the PET film is coated with the first adhesive (K1).
- the first adhesive (K1) used is an adhesive which can be activated by means of heat, the temperature during the contacting is selected in particular above the activation temperature of the adhesive, so that the adhesive cures immediately after the contacting and thus the adhesive bond takes place directly.

- the reinforcement is made by fibers so that the PVC film is reinforced with a fiber mat, a fiber fabric or a fiber fabric. As fibers in particular glass fibers or polyester fibers are suitable.
- the layer of the second adhesive (K2) on the side facing the polyethylene terephthalate film (F2) is in contact with a release film (F4).
- the release film can be removed from the waterproofing membrane so that the waterproofing membrane can be bonded to the substrate by the exposed adhesive.
- the release film is removed during the bonding process.
- the present invention relates to a release film
- Composite body which consists of a previously described sealing film as well as a substrate (S1) adhered thereto via the second adhesive (K2) of the sealing film.
- any suitable material can serve as the substrate (S1).
- substrates (S1) are building materials such as concrete, gypsum, stone, brick, mortar, fiber cements and natural stones such as granite or marble; Metals or alloys such as aluminum in aluminum, steel, non-ferrous metals, galvanized metals; Wood, insulation foams, polyisocyanurate resins (PIR); coated substrates such as coated metals or alloys; as well as paints and varnishes.
- materials such as those used as a roof substrate.
