Definitions

  • This invention relates to the field of substrate coating, in particular thermo-acoustic insulation and the sealing of essentially flat roofing, and it has as its object a process for insulating and sealing such roofing and a liquid vapor-barrier coating that is suitable for the implementation of such a process.
  • the sealing systems (insulation+outside sealing membrane) should either have ballast or should adhere perfectly to the substrate.
  • the vapor-barrier membranes are generally thin structures that are subject to tearing or to perforation during their handling and after installation.
  • the insulation is generally bonded to the vapor-barrier membrane only by spaced zones, from which there results a limited attachment force and the impossibility of attaching low-cohesion insulations;
  • the discontinuous structure of the insulating layer (foam panels)
  • the latter necessarily will not be sealed at least over the long term, and in particular at the joints between adjacent panels, even if the panels have, in themselves, a water-tight structure. During ageing of said system, infiltrations will therefore be produced, with stagnation of the water under the insulating panels.
  • This invention has as its object to remedy at least some of the drawbacks above and to overcome at least some of the above-mentioned limitations.
  • the invention has as its main object a process for insulating and sealing a roofing that forms an essentially flat substrate, such as a concrete terrace roofing, characterized in that it essentially consists of:
  • FIG. 1 is a side cutaway view of an insulating material that is attached to a concrete substrate according to the current process of the prior art
  • FIG. 2 is a cutaway view of an insulating material that is attached to a concrete substrate according to the process of the invention.
  • a sealing coating 6 that comprises at least one layer of bituminous or synthetic or analogous membranes.
  • the invention thus makes it possible to replace the three stages of the known process, mentioned above (and whose result is illustrated in FIG. 1) and costly in labor and in materials (three different materials), by a single operating stage, by using a product in coating form 3 that is easy to spread on substrate 2 and that simultaneously performs the following three functions: vapor barrier (controlled vapor barrier), adhesion to substrate 2 and bonding of insulation 1 .
  • composition 3 that forms a coating is selected from the group that is formed by the bituminous compositions based on a bitumen/thermoplastic elastomer mixture and the compositions that are based on a bitumen/polyurethane mixture or in the group that is formed by the mixtures that are based on a polyurethane prepolymer, with or without solvent, and the resin/hardener mixtures (such as, for example, epoxy resin/amine hardener).
  • the resin/hardener mixtures such as, for example, epoxy resin/amine hardener
  • composition 3 that forms a coating has a viscosity at 20° C. of between 50 and 300 poise, preferably between 100 and 200 poise and very preferably between 100 and 150 poise.
  • composition 3 thus will be fixed such that the coating can be carried out by means of a brush, a roller, a spatula, a scraper or a similar tool and has a good spreadability of between 5 and 40° C.
  • the amount of liquid or viscous composition 3 , continuously applied over the entire surface of substrate 2 is at least adequate to obtain a smooth upper surface (compensation for rough spots of substrate 2 ) and to ensure an adhesion of insulating layer 1 to essentially its entire lower face.
  • This arrangement will make possible the bonding of low-cohesion insulating materials (mineral wool and perlite, for example), while providing a coating layer 3 , linking insulating layer 1 to substrate 2 , with a high structural cohesion due to homogeneous consistency (relative to three layers [primer/vapor barrier/glue] of the prior art).
  • low-cohesion insulating materials mineral wool and perlite, for example
  • the coating that is used preferably in the form of an essentially liquid composition, should comprise a mixture of substances that are compatible with one another and that contribute in combination to the expression of the three above-mentioned functions, whereby each of them can be accomplished in practice in several different ways, if necessary by acting on several parameters and/or on the types and the amounts of compounds falling within its formulation.
  • bitumen that may or may not be modified, thermoplastic elastomers, epoxy resin monocomponent polyurethane prepolymer or bicomponent polyurethane prepolymer or the like.
  • the water vapor-barrier function can be accomplished by integrating in coating 3 materials or substances that have good hydrophobic properties and that are resistant to the transfer of water vapor. In some cases, the bitumen by itself is adequate to obtain a vapor-barrier function to a sufficient degree.
  • an existing cold bonding solution optionally can be combined with coating 3 that is used within the scope of the invention.
  • bituminous glue [0045] Found among these potential solutions is in particular solvent-containing bituminous glue, polyurethane glue and bitumen/monocomponent or bicomponent polyurethane glue.
  • This invention therefore also has as its object a coating that is used for the implementation of the process that is described above, making it possible in particular to perform the three functions that are mentioned above.
  • coating 3 consists of a preferably essentially liquid composition, i.e., a viscosity as mentioned above and that comprises, by weight:
  • At least one structuring and adhesive component that is selected from the group that is formed by the thermoplastic elastomeric polymers, the polyurethane prepolymers and the resin/hardener mixtures.
  • composition 3 consists of, by weight:
  • At least one structuring and adhesive component that is selected from the group that is formed by the thermoplastic elastomeric polymers, the polyurethane prepolymers and the resin/hardener mixtures.
  • thermoplastic elastomer or elastomers that modify the bitumen can, for example, be selected from the group that is formed by SBS (styrene-butadiene-styrene), SIS (styrene-isoprene-styrene), EVA (ethylene/vinyl acetate copolymer) and mixtures of the latter.
  • SBS styrene-butadiene-styrene
  • SIS styrene-isoprene-styrene
  • EVA ethylene/vinyl acetate copolymer
  • Bitumen is advantageously a direct distillation bitumen, for example of type 70/100.
  • the coating can also be carried out with an oxidized or semi-blown bitumen.
  • composition 3 consists of a mixture that is based on reactive resin, preferably consisting of, by weight:
  • composition 3 consists of a mixture without a solvent that is based on polyurethane prepolymer, preferably consisting of, by weight:
  • At least one said mineral or metal feedstock can be selected from the feedstock that is selected from the group that is formed by slate powder, aluminum paste, chalk, aluminosilicates and mica.
  • the feedstock preferably consists of laminating flakes that, after coating 3 dries, form a continuous film on the aluminum or mica surface.
  • coating 3 consists of a monocomponent composition.
  • coating 3 consists of a bicomponent composition of which a first component comprises in particular a polyol and of which the second component comprises in particular an isocyanate.
  • the polyol/isocyanate pair can, for example, correspond to the hydroxylated polybutadiene/methyldiphenyldiisocyanate pair.
  • coating 3 consists of a bicomponent composition, of which a first component comprises in particular an epoxy resin and of which the second component comprises in particular an amine hardener.
  • coating 3 can comprise an additional structuring feedstock in the form of short fibers 5 , preferably fibers made of a polymer material.
  • Component A Component B: Direct distillation bitumen, 40.00 preferably 70/100: Solvent: 10.00 MDI: 2.50 Plasticizing oil: 8.00 (methyldiphenyldiisocyanate) Slate powder: 21.00 A/B ratio: 40/1 Hydroxylated polybutadiene: 21.00 Adhesion: Amount of glue applied: 1.5 kg/m 2 PSE adhesion (expanded polystyrene: 25 kg/m 3 ) on concrete: 1.2 daN/cm 2 (cohesive rupture in PSE) Water vapor permeability: Less than 0.1 g/m 2 .24 h
  • Direct distillation bitumen 40.00 preferably 70/100: Solvent: 13.00 Tackifying resin: 4.00 SBS/SIS mixture: 3.00 Slate powder: 18.00 Aluminum paste: 22.00 Adhesion: Amount of glue applied: 2 kg/m 2 PSE adhesion to concrete after 28 days: 6 N/cm 2 (50% cohesive rupture in PSE; 50% cohesive rupture in adhesive binder) Water vapor permeability: 0.10 g/m 2 .24 h.
  • the invention also has as its object a composite insulating and sealing system for roofing that forms an essentially flat substrate, such as a concrete terrace roofing, obtained by means of the process above, characterized in that it has a stratified composite structure and consists of, starting from substrate 2 , a dried or polymerized coating layer 3 that simultaneously forms a controlled passage water vapor barrier, a leveling coating and an agent for surface adhesion to substrate 2 , by an insulating layer 1 that is attached by coating layer 3 to substrate 2 , whereby said insulating layer 1 is preferably formed by the juxtaposition of individual elements in the form of strips or panels, and by a sealing coating 6 that comprises at least one layer of bituminous, synthetic or analogous membranes, whose adjacent edge zones advantageously at least partially overlap one another.
  • Upper sealing coating 6 can be formed in particular by a layer that consists of bituminous membranes that are cold or hot glued to insulating layer 1 , whereby these membranes are themselves provided with an upper coating of mechanical and/or chemical protection, integrated with said membranes.
