Definitions

  • the invention relates to the making of self-plugging and/or non-dripping roofing construction.
  • a modern roof design normally includes a structure to carry loads, insulation to control heat flow, a barrier to control air and vapour flow, and a roofing element to prevent water penetration.
  • Built-up roofing is a continous membrane covering manufactures on site from alternate layers of bitumen, bitumen-saturated felts or asphalt-impregnated glass mats, saturated and coated felts, and surfacings.
  • roofing membranes can also be liquid-applied as a single or two-component system with polymeric fabrics or glass-fibre reinforments. « hatever the type of roof and roofing construction and material used, water leaks and condensation can occur, particu ⁇ larly in the spring in cold climates when the snow on the roof.
  • 2MPI is melting, or during so heavy rain falls that the roof-gutters cannot cope with the amount of water on the roof.
  • Water leakage and dripping for roofing constructions can have considerable economic consequences, even when the amount of water is small, for instance because the leakage site is of very small size, perhaps only a small nail hole. It is also extremely difficult to locate such leakage sites, the more dif ⁇ ficult the smaller the leak.
  • the object of the invention is to solve the above mentioned problems and to provide a method which makes it pos ⁇ sible to achieve a self-plugging, i.e. a self acting leak-stop ⁇ ping and/or non-dripping roofing construction.
  • This object is achieved by a method in which a layer is incorporated in the roofing construction, which layer contains hydrophilic polymers and/or known inorganic viscosity- increasing and/or gel-forming hydrophilic substances.
  • the invention also relates to a roofing construction provided with a layer of the above type.
  • the present invention solves these problems in a simple and economic way by making use of the special properties which hydrophilic polymers and/or certain hydrophilic inorganic sub ⁇ stances possess for increasing the viscosity of water to such an extent that it will not drip from the roofing construction, and/or to bind the water in the form and consistency of a gel.
  • Such polymers and inorganic substances can also by water be brought to swell to such an extent that a leakage is stopped by itself.
  • the hydrophilic polymers which can be used with the method can either be water-soluble or water-swellable, or a combination of both. The same applies for the inorganic subs ⁇ tances.
  • Water-soluble polymers and/or water-soluble inorganic substances of the mention type can be made non water-soluble through partial cross-linking, i.e. cross-linking which leaves a number of hydrophilic groups free to bind water molecules.
  • hydrophilic polymers and/or inorganic hydrophfeic sub ⁇ stances can be incorporated in many different ways in the
  • hydrophilic polymers which can be used for the method can be mentioned natural hydrophilic polymers such as gum arabic, traganth and karaya, semi-synthetic hydro ⁇ philic polymers such as carboxymethylcellulose, methylcellulose and other cellulose ether ' s, lignin derivates, various kinds of modified starches (ethers and acetates), and synthetic hydro ⁇ philic polymers such as polyacrylic acids, polyacrylamides, and polyethylenoxide, polyvinyl pyrrolidone, polyethylenimine and others, as well as combinations of such polymers or with other substances.

  • inorganic substances which can either be used alone to bind water in the form of a gel or a highly vis ⁇ cous fluid, can be mentioned water glass, alumina, magnesia, betonite etc. and mixtures of such inorganic hydrophilic sub ⁇ stances or mixtures of these and hydrophilic polymers.
  • hydrophilic polymers and/or hydrophilic inorganic substances can eventually be cross-linked, either in the form of a pre-crosslinked film or sheet or similar or a layer cross-linked in situ.

Abstract

Afin de rendre une construction de toiture étanche aux fuites, on la dote d'une couche contenant des polymères hydrophiles et/ou des substances inorganiques connues augmentant la viscosité et/ou formant un gel. Cette couche peut être incorporée à la construction sous la forme d'une membrane ou d'un revêtement, ou alors elle peut être répartie en tant que poudre. Grâce à cette couche, la construction de toiture deviendra auto-isolante.
