Definitions

  • the invention relates to a bituminous roofing membrane with a carrier insert coated on both sides with bitumen and a plastic fleece applied to the top.
  • roofing membranes hereinafter referred to briefly as roofing membranes, usually consist of a carrier insert coated on both sides with bitumen, which is provided with mineral scattering on the top and on the underside.
  • bitumen which is provided with mineral scattering on the top and on the underside.
  • roofing membranes are only partially non-slip and pose a safety risk when the roof area has to be walked on.
  • roofing membranes which are laminated on one side with a relatively thick and heavy plastic fleece as a mechanical protective layer; the plastic fleeces have weights in the range of 200 to 500 g / m2.
  • bituminous sealing sheets on their top or bottom with elevations or depressions.
  • bitumen which is used as a covering layer for the waterproofing membrane, is subjected to a very strong cold flow.
  • the depressions or ridges embossed into the surface of the bituminous surface flow together within a few months and even out.
  • bitumen compositions which, at the temperatures occurring on the roof, for example at temperatures up to 80 ° C., have no flow over a long period of time; these masses are mixtures of bitumen, fillers, plastic additives and in particular fiber materials.
  • highly reinforced bitumen materials cannot be produced on conventional systems for producing roofing membranes, since the viscosity of these materials is too high for processing on these roofing membrane systems.
  • bituminous roofing membrane of the type described in the introduction in that the bitumen coating is structured on the upper side with the formation of bead-like or knob-shaped projections and that the applied plastic fleece is embedded in the bitumen coating in the area of the projections, while it lies essentially on the bitumen layer in the area between the projections.
  • the plastic fleece is a polypropylene or polyester fleece with a weight per unit area of 10 to 50 g / m2. It is therefore a very thin fleece, which can follow the structure of the bitumen surface, so that the structure of the bitumen top can also be seen through the thin plastic fleece.
  • the projections can preferably have a height of 0.1 to 1 mm and a width of 1 to 5 mm. It is advantageous if the projections rib or bulge extend substantially in the longitudinal direction of the web.
  • At least 10 projections can be provided over a web width of 10 cm.
  • the thickness of the plastic fleece is less than the height of the projections.
  • the invention is furthermore based on the object of specifying a method for producing a non-slip roofing membrane, in which the support insert is coated on both sides with heated and therefore flowable bitumen and the roofing membrane is cooled.
  • the drawing shows a schematic sectional view through a roofing membrane with a structured top and with a plastic fleece applied on the top to stabilize the surface structure.
  • the roofing membrane shown in the drawing comprises a carrier insert 1, which is designed, for example, as a glass fleece, glass fabric, plastic fleece, plastic fabric or plastic film, as is usual with roofing membranes per se.
  • This carrier insert 1 is provided on both sides with a bitumen coating 2 or 3.
  • the coating materials used for this correspond to those that conventionally Lich used for roofing membranes, for example one of the bitumen masses specified below can be used:
  • bitumen B 200 15% by weight atactic polypropylene 20 percent by weight limestone flour.
  • the carrier insert 1 is coated on both sides with the bitumen mass on a conventional system for producing roofing membranes, the bitumen mass being heated for this purpose to such an extent that it is readily flowable.
  • the top of the bitumen coating 3 is profiled, for example by means of suitable profile rollers.
  • beaded or nub-shaped projections 4 are formed in the surface, which rise, for example, 0.1 to 1 mm above the top of the bitumen coating 3.
  • these projections can run essentially parallel to the direction of the web, it is advantageous liable if at least 10 such beads come in 10 cm web width.
  • a thin plastic fleece 5 is placed on this structured surface, for example a polypropylene fleece or a polyester fleece with weights per unit area of 10 to 50 g / m2.
  • This fleece has a thickness which is preferably less than the thickness of the projections.
  • the plastic fleece 5 initially sinks into the still flowable bitumen mass of the bitumen coating 3 in the area of the projections 4, while it is still held at a distance from the top of the bitumen coating 2 between the projections 4 by the projections 4. By sinking the plastic fleece 5 into the projections 4, they are reinforced and thus stabilized, particularly in their near-surface area, so that the tendency of the bitumen to flow together and thus to level the structuring is reduced considerably.
  • the roofing membrane is cooled in a conventional manner, the profiling of the surface stabilized by the plastic fleece 5 being "frozen” so that it is retained.
  • the plastic fleece is embedded in the bitumen mass in the area of the projections 4, and preferably in the surface area, while the plastic fleece lies essentially on the bitumen layer in the lower areas lying therebetween, or at least slightly in this dips.
  • the arrangement of the plastic fleece 5 is shown very schematically, in fact the fleece will not adhere to the profiled surface of the bitumen mass as precisely as is shown in the drawing.
  • the surface of the roofing membrane shows areas next to one another, which essentially consist of plastic-reinforced bitumen or of a plastic fleece that is only slightly bound to the underlying bitumen layer and is otherwise completely exposed. This significantly increases the overall slip resistance of such a web. It is particularly advantageous in this construction that the profile structure of the surface is retained even if the bitumen mass is softened by increasing the temperature, since the plastic reinforcement in the area of the projections leads to an increase in viscosity overall and thus counteracts a flow of the projections.
  • the plastic fleece is so thin that it adapts to the structure of the profiled bitumen surface and enables the bitumen in the area the projections penetrate the fleece to such an extent that fiber-reinforced bitumen regions emerge on the surface, which are separated from one another by the intermediate regions of the plastic fleece that do not escape into the bitumen.
