Definitions

  • the present invention relates to a thermal and acoustic fire-insulating material, in particular for insulating buildings.
  • It relates more particularly to a thermal and acoustic insulation material based on air bubble films and possibly based on fluid polyethylene fire-resistant foam.
  • US Pat. No. 4,038,447 discloses a flame-resistant insulation cover made up of a bubble film folded back on itself along a longitudinal line and then covered with a cover of synthetic material forming a pocket, the side edges are assembled by staples, leaving a free passage of air between the outside and the inside.
  • Such an insulator does not provide sufficient flame resistance despite the presence of flame retardant additives.
  • the invention relates to an improvement to US Pat. No. 4,038,447 which describes a cover for protecting concrete against frost.
  • the advantage of the latter compared to that used hitherto is its non-flammable power, its ease of transport and its easy implementation.
  • This cover is made up of two layers of air bubble film coated with a non-flammable material assembled together by a graffiti on the periphery of the cover and the establishment of rivets on the rest of the surface. There remains, however, an air passage within the cover which does not allow obtaining sufficient safety assurances with regard to the flame as well as a reduction in the expected thermal characteristics.
  • the product is assembled in such a way that the aluminum sides are on the outside and welded to the sides of the two sheets lengthwise.
  • Air bubble films are already known, in particular made of polyethylene. These films are generally used for packaging or as a thermal insulator. Polyethylene foams are generally used in acoustic protection.
  • the most commonly used thermal and acoustic insulation in buildings is glass wool.
  • the main advantage of this product is that it is inexpensive. However, it has the disadvantage of being thick and heavy, flammable and above all delicate and unpleasant to handle because of the glass dust it generates in its environment. So people who regularly handle glass wool should not be allergic to glass dust and are often prone to irritation or even damage.
  • the object of the invention is to provide an air bubble film and a polyethylene foam which are totally unalterable when the materials are exposed to ultraviolet radiation and when they represent good characteristics of mechanical resistance and flame resistance and to heat while having a good acoustic characteristic.
  • the object of the invention is also to provide a fire-resistant thermal and acoustic insulator, in particular for the insulation of buildings, offices and industry, which is light, not very thick, unalterable when exposed to ultraviolet rays sufficiently flame resistant to meet the standards required in the construction of buildings, inexpensive and that is clean and easy to handle.
  • the insulating material comprising a sandwich formed of two aluminum sheets between which are arranged polyethylene films forming between them air bubbles is characterized in that it comprises an assembly formed of at least two films of synthetic material containing air bubbles, which are made uniformly integral at one of their respective faces by a heating process, optionally trapping between each of said films at least one layer of polyethylene foam, the external faces of the assembly of insulating material being covered with a layer of fire protection.
  • the insulating material mainly comprises two films 2 of synthetic material containing bubbles 3, in particular air bubbles regularly distributed, but possibly of different density, and each of the outer faces of the films forming the insulator is covered with a protective coating 1, such as in particular a continuous layer comprising aluminum and which is welded on at least one of the two faces.
  • At least two films 2 are made integral at the level of their face not coated with the protective layer, by a heating operation which allows uniform welding by thermoplastic fusion.
  • the insulation object of the invention there is interposed between at least two films 2, at least one layer 4 of insulating material, of variable thickness, such as in particular a layer of fluid polyethylene foam in sheet .
  • the bubble plastic layer is, for example, a layer of flame retardant polyethylene
  • the insulator according to the invention may comprise a plurality of assemblies consisting of at least two films of bubbles made integral on one of their faces, the other faces being covered with a layer of aluminum 1; it being understood that, according to a variant, at least one layer of variable thickness of insulating foam 4 is interposed in at least one of the assemblies of bubble films.
  • the films according to the invention are opaque to radiation, reflect radiation and are impermeable to liquids and / or gases.
  • Polyethylene foams are flame retardant and good receptors of acoustic frequencies.
  • bubbles of different dimensions distributed over the surface of the film according to a desired density, it is possible to adjust the frequency response of the film so, thanks to the specific frequency at the resonance of the bubble, to cancel the propagation of the sound.
  • the aluminum layer 1 is an aluminum film attached to a polyethylene film which is welded to the layer of synthetic material 2 with bubbles 3.
  • the insulator according to the invention has several thicknesses of a minimum of 7 mm comprising at least two films of flame-retardant air bubbles, 10 mm bubble having 3.5 mm thickness.
  • a minimum thickness of 7 mm comprising at least two films of flame-retardant air bubbles, 10 mm bubble having 3.5 mm thickness.
  • 18 mm bubbles 7 mm thick to have a maximum thickness of 28 mm.
  • a 30 mm bubble with a thickness of 14 mm is provided.
  • the bubble polyethylene is mixed in a mixing silo (20) with the adjuvants allowing it to be flame retardant and with any other additives (dyes, etc.) following, for example, 95% of polyethylene is mixed with 3% of aluminum 50 and 2% of dyes.
  • a hollow drum (26) (27) is used on which a strip (24) of hot polyethylene is wound, from an extrusion / laminating device (21) to form bubbles with this strip.
  • a roller (31) pressing and welding a second strip (25) of hot synthetic material, in particular hot polyethylene against the first strip (24) wound on the drum (26).
  • the installation comprises a feed drum (32) on which the aluminum foil is wound, and means (33) for preheating the aluminum foil disposed between the feed drum (32) and the means (34) allowing to press and weld the aluminum foil on the layer of bubble plastic at the drum outlet (26).
  • the preheating means (33) consist of a roller (33) kept hot and coming into contact with the aluminum sheet, for heating a polyethylene film of this sheet through the aluminum film.
  • the insulation according to the invention consists of several thicknesses of films with air bubbles superimposed on each other and associated with each other by their hot-welded surfaces.
  • the films of 30 microns of aluminum being heat welded on the surface are always turned towards the outside and constitute the outside faces of figure 1.
  • the tests were carried out and surprisingly showed that an insulator according to the invention has a high resistance to fire (classification M1) a life greater than 10 years classified as rot-proof and 0 to humidity by the CEBTP.
  • the invention consists in improving the insulating product in its new design, by hot gluing the films of air bubbles between them in such a way that when we make cuts that the product remains whole in its thicknesses and waterproof.
  • the second improvement is to allow the offset from the left and right of the product to offset a better thermal and phonic seal.
  • the invention therefore relates to a sound and thermal insulating material on the basis of films with air bubbles and an envelope of a film of aluminum welded hot to be able to resist fire.
  • the material resulting from the manufacture by superimposition of flame-retardant bubble polyethylene films is assembled by hot gluing to form a sandwich that can be cut without having to reconstitute the insulating product by stapling.
  • the figure shows a perfect assembly by hot gluing to form a sandwich which can be cut without having to reconstitute the insulating product by stapling.
  • the thermal and phonic fire-resistant insulation in the form of a sheet, in particular for the insulation of buildings consists of at least two thicknesses superposed one on the other so that the layers comprising aluminum of thicknesses form the outer faces of the insulation
  • the product bonded over its entire surface allows a better rigidity of the insulation which is thus easier to put in place and has better hold (no creation of belly during use under roof or ceiling).
  • the insulating assemblies according to the invention can either be covered with a coating or be bonded to an acoustic correction material such as in particular a rigid panel (plaster, wood, decor panel, panel made of composite material (fiberglass, carbon fiber) on one or both sides with or without battening of wood or synthetic material and be fitted with a sealing device between the panels in order to avoid thermal and sound bridges and to avoid damage by humidity.
  • an acoustic correction material such as in particular a rigid panel (plaster, wood, decor panel, panel made of composite material (fiberglass, carbon fiber) on one or both sides with or without battening of wood or synthetic material and be fitted with a sealing device between the panels in order to avoid thermal and sound bridges and to avoid damage by humidity.
  • the product thus obtained is really suitable for insulating buildings but also in the industry for ventilation ducts in noisy rooms, boats, caravans ...
