Definitions

  • the present invention relates to a new type of material based on a nonwoven textile web usable as reinforcement for waterproofing coatings consisting of a support embedded in a bitumen composition.
  • the oldest is the one that Arthur had used to build his ark.
  • the material most suitable for fulfilling all these characteristics is, to date, constituted by a complex formed of a polyester nonwoven associated on one of its faces with a glass textile grid.
  • the invention therefore relates to a material that can be used as a reinforcement for bituminous waterproofing coatings, said material being of the type constituted by a nonwoven fibrous web and being characterized in that said web is formed from a complex comprising an intermediate layer constituted by a polyester nonwoven, this nonwoven serving as a support for glass fibers implanted in its thickness, fibers which protrude on each side of said support and are folded against it.
  • the internal polyester-based layer is a nonwoven produced from continuous filaments, relatively compact and of small thickness, the glass fibers being implanted in the nonwoven by needling.
  • Such a material is obtained, in a simple manner, by superimposing the internal polyester ply with a ply of glass fibers, said glass fibers having such a length. that when the assembly is subjected to a needling operation, they are implanted in the ply of. polyester and come out, on the face opposite to that where the action of the needles takes place, in the form of loops.
  • the assembly thus produced is then calendered and optionally impregnated using a tacky material of known type compatible with bitumen.
  • a material according to the invention is produced on a conventional installation making it possible to associate nonwoven webs, this installation essentially comprising a needling machine at the outlet of which is placed an impregnation tank, a calender and a drying oven.
  • a layer of polyester weighing 70 g / m 2 and a layer of glass fibers weighing 150 to 160 g / m 2 are introduced, superimposed, said fibers having a length of between 100 and 150 mm.
  • the glass sheet is arranged above the polyester sheet so that the needles of the needling machine entrain the glass fibers through the polyester sheet.
  • the needling machine is adjusted so that, as can be seen from the appended figure, the glass fibers (1) pass through the polyester sheet (2) and protrude on each side of this sheet.
  • the glass fibers (1) After calendering on one of the faces (3) for example of the sheet (2) the glass fibers (1) are in the form of flattened loops (4) while, on the other side, that is to say on the side through which the needles penetrate, said glass fibers (1) have two free ends (5a, 5b) also flattened against the other face (6) of the ply (2).
  • the assembly passes through an impregnation tank containing a binding material, for example an adhesive of the Styrene butadiene type, then between two cylinders allowing the assembly to be expressed and the glass fibers to be flattened against the faces of the polyester tablecloth.
  • a binding material for example an adhesive of the Styrene butadiene type
  • the adhesive is deposited at a rate of 130 g / m 2.
  • the complex thus produced can be stored in the form of a very long winding and then be coated with a layer of bitumen making it possible to obtain a sealed assembly four millimeters thick.
  • This assembly has excellent characteristics of dimensional stability and resistance to static and dynamic punching, making it particularly suitable for making a single-layer waterproofing coating.
  • the basic textile complex can easily be stored and handled, which has a certain advantage given that, in general, the bitumen coating is produced by other manufacturers than those manufacturing the reinforcements.
  • the invention is not limited to the embodiment described above, but it covers all the variants produced in the same spirit.
  • a single glass sheet and a single polyester sheet are used to produce the complex, it could be envisaged to trap the polyester sheet between two glass sheets, the assembly then undergoing needling on both sides.
  • other additional reinforcing elements such as for example a non-woven grid, a film could be interposed between the polyester and glass fibers.
