Definitions

  • Plastic roofing membranes are known. They usually consist of foils approximately 1 mm thick made of polyvinyl chloride (PVC). A mesh fabric 3 x 3 to 6 x 6 can also be inserted into the film for reinforcement, or such a mesh fabric is laminated between two thinner PVC films.
  • the roof covering sheets made of PVC have the advantage that they can be prefabricated and are therefore inexpensive and easy to install and have a higher water vapor permeability than sheets made of bitumen or synthetic rubber.
  • Their mechanical vulnerability to pointed objects, such as roof nails accidentally left behind or pointed gravel stones has proven to be disadvantageous. If PVC roof foils harden or become brittle and shrink over time, this is primarily due to the loss of plasticizer through evaporation, migration or decomposition. If a conventional PVC roof covering sheet is laid on a bitumen roof without an intermediate layer, part of the plasticizer migrates into the bitumen over time.
  • the invention has for its object to provide a roofing membrane that no longer has the disadvantages described and is characterized above all by great mechanical stability, against perforation caused by carelessness, or other damage, is practically insensitive in construction, any elongation or everyone Shrinking opposes, so that even after many years, no destructive tensions caused by shrinkage or on sloping roofs no elongations caused by tensile stress due to its own weight can occur.
  • the mechanical stability should be so great that punctiform fastening becomes the rule and the usual gravel can be dispensed with.
  • the roof covering membrane should be able to be manufactured in extremely large widths and should be so strong that it can be nailed down without any problems.
  • the water vapor permeability should be so high that the roof covering membrane, e.g.
  • the underside of the roof covering membrane should be bitumen-resistant so that the membrane can be laid directly on a bitumen roof that has become leaky and the old roof structure does not have to be removed beforehand.
  • a suitable chemical composition, both of the fabric and the PVC coating should ensure that the roof covering sheet has a long service life, even under extreme conditions, so that, for example, the usual gravel is not required for flat roofs.
  • the roof covering membrane should be flame-retardant in the sense of the building regulations, because even the renovation of an easily flammable roof leads to much greater resistance to flying sparks and radiant heat simply by covering with such a membrane.
  • roof covering sheets made of a PVC-coated fabric on both sides in that the fabric is a full fabric made of high-strength synthetic single fibers or continuous yarns with a basis weight of 150 to 300 g / m 2 and a fabric tear strength of at least 200 daN / 5 cm.
  • Fabrics made of polyesters or aramids customary for textile purposes are particularly suitable.
  • the use of such a tightly closed or closed fabric made of high-strength fibers forms a barely destructible and extremely dimensionally stable backbone of the roof covering sheet according to the invention and reduces the risk of perforations, elongation or shrinkage to a minimum.
  • the great mechanical stability enables punctiform attachment.
  • the PVC coating of the top and bottom of the roof covering sheet according to the invention is preferably different and adapted to the respective requirements. If, according to a preferred embodiment of the invention, the underside is to be bitumen-resistant, the PVC coating here contains only polymer plasticizers as plasticizers. These are customary in the trade. Polyester plasticizers based on dicarboxylic acids with 4 to 10 C atoms and diols with 2 to 6 C atoms have proven particularly useful. The polymer plasticizers are used in a ratio of about 85 to 105 parts by weight to 100 parts by weight of PVC. The advantage of polymer plasticizers is that even when laying on bitumen, they do not migrate into the bitumen, but remain in the PVC coating and therefore prevent it from hardening or becoming brittle.
  • plasticizers are selected for the top layer of the roof covering sheet, which are immiscible with the polymer plasticizer of the bottom layer. This ensures that Even the plasticizer of the top layer cannot migrate through the fabric and the bottom layer into the bitumen of an old roof covering if the roof covering sheet is used for a long time.
  • Suitable plasticizers for the upper coating which are very stable and not very volatile and therefore neither evaporate nor be destroyed by weather influences, are, for example, phthalate plasticizers with 12 to 24 aliphatic carbon atoms in the alcohol component of the ester. If it is not important during use that the roof covering sheet is resistant to bitumen, oily wood preservatives or the like, the plasticizers customary for PVC, in particular phthalate plasticizers, can also be used for the lower coating.
  • the roof covering sheets according to the invention are produced anyway by a plurality of spreads applied one after the other, it has proven to be particularly advantageous to use this production technique for the lower and / or upper coating to consist of 6 to 10 differently composed individual layers.
  • the usual UV absorbers e.g. based on anthraquinone derivatives, mainly incorporated in the outer cover layers of the top in concentrations of 0.05 to 0.5 percent by weight of the coating.
  • the pigments such as. B. Titan white, which ensures that the top is not only extremely light and weather resistant, but also very bright. This results in a strong radiation of incoming solar heat and, as a result, a lower temperature of the roof skin. This is also beneficial for the life of the roof covering.
  • the construction of the roof covering sheet according to the invention in different layers makes it possible to use different fungicides, e.g. To accommodate arsenic, tin or mercury compounds in concentrations of 1 to 3 percent by weight of the coating in different layers. You then get by with smaller amounts of the fungicide in the individual layer and this increases the compatibility of the fungicides with the PVC and the other necessary additives such as stabilizers and additives. Fungi that have developed a certain resistance to a certain fungicide after a long time then encounter a fungicide in the next layer that they are not yet resistant to. This also increases the service life of the roof covering membrane constructed in this way.
  • fungicides e.g. To accommodate arsenic, tin or mercury compounds in concentrations of 1 to 3 percent by weight of the coating in different layers. You then get by with smaller amounts of the fungicide in the individual layer and this increases the compatibility of the fungicides with the PVC and the other necessary additives such as stabilizers and additives. Fung
  • the roof covering sheets according to the invention also contain the other stabilizers and additives which are customary for PVC roofing sheets and which ensure, for example, that the roof covering sheet is hydrolysis-proof, or that traces of acids, e.g. neutralized and rendered harmless by the addition of active calcium carbonate.
  • the flame-resistant equipment is made with the usual additives, e.g. B. by incorporating antimony trioxide in amounts of 5 to 18 weight percent, based on the coating.
  • top and / or bottom with a top coat is preferably made of polyvinyl halides and has, among other things. an effective barrier against plasticizer losses. Top coats consisting primarily of polyacrylates have also proven their worth.
  • the cover sheets according to the invention can be manufactured in extremely large widths of 205 to 320 cm. This makes installation easier and increases safety because fewer weld seams are required.
  • the top of the roof covering sheet can be embossed, for example in the form of flattened pyramids, in order to make the sheet non-slip and non-slip.
  • the roof covering membrane according to the invention fulfills the requirements set out at the outset and, due to its high strength and the special chemical structure, solves all problems with warm roofs, cold roofs, laying on wood, concrete, steel roofs, flat roofs, sloping roofs, and direct laying on bitumen roofs and sched roofs in need of repair Inclinations and constructions.
  • the major advantage of renovating old roofs is that the old roof covering does not have to be removed, with moisture and cracks not playing a role. Gravel can be dispensed with for flat roofs, even on high-rise buildings.
  • the adhesive coat (approx. 100 g / m 2 ) additionally contained 5% by weight of an isocyanate-based adhesion promoter and 1% by weight of a fungicide A.
  • the first top coat (approx. 300 g / m 2 ) additionally contained 1% by weight of a second fungicide B.
  • the second top coat (approx. 300 g / m 2 ) additionally contained 1% by weight of a third fungicide C and 0.25% by weight of an anthraquinone-based UV absorber.
  • the paste contained the usual stabilizers and pigments known to the person skilled in the art and 5% by weight of Sb 2 0 3 as a flame-retardant additive.
  • the first top coat (approx. 300 g / m 2 ) additionally received 1% of the fungicide B, the second top coat (approx. 300 g / m 2 ) 1% of the fungicide C.
  • top coat which mainly contained acrylates.
  • the result was a product that is excellently suited for roofing.
