Definitions

  • Said sealing material is a composite material consisting of at least one layer of bituminous composition on a reinforcement structure or reinforcement. It is generally a "sandwich” type material consisting of two layers of a bituminous composition on either side of a reinforcement structure or reinforcement. We speak of "leaves” impregnated or surfaced with a bituminous composition. Said composition may contain, in addition to bitumen, polymers, copolymers, inert or mineral organic fillers.
  • the reinforcement structure arranged in the form of a grid or fabric, is a frame of mineral or organic fibers. Glass fibers or polyester fibers are generally used.
  • Material audit mainly consisting of a reinforcement structure within a bituminous composition, can be added a layer of solder, based on polymer, polyolefin type, to facilitate installation.
  • sealing coatings are multiple. Such coatings are used in the construction of many building and civil engineering works, and in particular in terraces.
  • the present invention therefore relates to a new sealing material consisting of a bituminous sheet inside which is placed a network of woven or non-woven fibers characterized in that said network consists of fibers of glass containing 0.05 to 3% carbon fibers.
  • Bituminous sheets are understood to mean products, in sheets, consisting of tar, bitumens, oxidized bitumens or bitumens modified by the addition of products such as resins, elastomers, polymers and rubbers.
  • the invention will be particularly useful in the case of the use of bitumens containing block styrene-butadiene polymers and / or atactic polypropylenes.
  • the proportion of carbon fibers relative to glass fibers has been fixed at 0.05 to 3% by weight because below the limit of 0.05% no significant influence of carbon fibers has been detected, on the properties of the material, and above the 3% limit the evolution of the properties of the material is much weaker.
  • a 4 mm thick sealing material was produced using a bitumen containing 15% of a styrene-butadiene block copolymer reinforced by means of a glass grid of 100 g / m2.
  • Such a material shows a deformation of 5% when it is subjected to a force of 15 daN / cm.
  • the product of said deformation by said effort is therefore 0.75.
  • Example 1 was reproduced by replacing, according to the invention, the reinforcement of the bituminous layer by: - or (example 2) a sheet of glued fibers of 60 g per m2 composed of a mixture of carbon fibers and glass fibers in the proportion of 1 g of carbon fibers per 60 g of glass fibers; - Either (Example 3) a glued grid made up of 2 threads per centimeter, one thread out of two being made up of a mixture of 98% by weight of glass fibers and 2% by weight of carbon fibers.
  • the proportion of carbon threads may be greater at the edge of the final product than in the middle thereof or may be greater in the parts of said final material which will be most exposed to moisture.
