Definitions

  • the invention refers to insulating materials.
  • bubble wrap which comprise at least two films of plastic material, whereof at least one is formed with bubbles and is bonded to the other at least in the areas around said bubbles.
  • continuous webs of plastic film are generally pre-heated to a suitable temperature, at least one of the webs being shaped with bubbles by passing on a roller with a shaped surface connected to a suction system, and finally the webs are coupled together on a calender, incorporating ambient air into the sealed bubbles that they form.
  • Said sheets are also used for insulation.
  • use of an air space, or air bubbles imparts an insulating power, but its effect is relatively scanty, in that the nitrogen and oxygen predominantly present do not provide a particularly good insulating power.
  • the presence of oxygen gives rise to the risk of fuelling fires.
  • the state of the art also comprises insulating materials, used for example for buildings or for greenhouses, generally consisting of sheets of expanded material or sandwich- type laminates, for example glass-plastic laminates, or double glazing with an air space.
  • Glass or plastic laminates and double glazing are rigid and costly and generally find their use in different fields from those where flexible sheets are used.
  • the object was therefore to create an effective, low-cost insulating material that is not dangerous and has an effective extinguishing power, usable for a wide variety of uses.
  • a bubble film according to the invention has two or more sheets, whereof at least one is formed with bubbles, bonded together so as to seal the bubbles, said bubbles being filled substantially with carbon dioxide.
  • the film also comprises a sheet of reflecting material.
  • the invention provides an insulating material with good insulating properties, that is not dangerous, is easy to transport and use, with a non-polluting manufacturing process and effective extinguishing power.
  • Figure 1 is a broken off perspective view of an example of a bubble sheet according to the invention
  • Figure 2 is a broken-off cross- enlarged sectional view, , through the bubble sheet of Figure 1
  • Figure 3 is a broken-off cross-sectional view through a variant of the bubble sheet
  • Figure 4 is a broken-off cross section through a further variant of the bubble sheet
  • Figure 5 is a very schematic illustration of an exemplary plant for the production of the sheet of Figure 1.
  • a sheet of bubble material according to the invention is designated as a whole with reference numeral 10 and comprises a first layer or film 11, substantially flat, and a second layer or film 12, shaped with circular bubbles 13.
  • the two layers are bonded together in the areas surrounding the bubbles, so as to close said bubbles tightly.
  • the gas filling the bubbles is completely or mostly carbon dioxide (CO2).
  • Figure 3 illustrates a second embodiment of the invention, consisting of an insulating sheet 20, which comprises three films, that is to say a flat film 21 and a bubble film 22 bonded together as explained above with reference to the films 11 and 12, to form sealed bubbles 23, and a further film 24 bonded to the film 22 at the tops of the bubbles 23.
  • the films 22, 23 and preferably also 21 are therefore bonded together at least at the edges of the sheet, as can be seen on the left in Figure 3, to define one or more further airtight chambers 25 around the bubbles, between the film 22 and the film 24.
  • the layer 24 can be of polyethylene or another thermoplastic material, or it can be a metallized or in any case reflective material, provided with a layer of bondable material.
  • the sheet material 30 comprises a plurality of base films 31, 31' and a plurality of bubble films 32, 32', besides a flat intermediate film 34.
  • Bubbles 33 can be formed between the sheet 31 and the sheet 32, bubbles 33' between the sheet 31' and the sheet 32'.
  • At least one of the films can be reflective.
  • Sheet materials with a carbon dioxide-filled space other than a bubble sheet also come within the scope of the invention, for example a double-walled glass or plastic sheet with an inner chamber between the sheets sealed and filled with carbon dioxide.
  • Figure 5 schematically illustrates an example of a plant for production of bubble film according to the invention.
  • the plant comprises a sealed chamber, indicated as a whole with reference numeral 50, at least one inlet 51 for a web Nl of thermoplastic film and an inlet 52 for a web N2 of thermoplastic material.
  • the webs are preferably heated inside the chamber, by passing around heating rollers 53, 54.
  • a shaping suction roller, per se known, designated with numeral 55, and a coupling calender 56, per se known, are comprised within the chamber.
  • An outlet for the formed bubble web is designated with the numeral 57.
  • the inlets 51 and 52 are provided with a series of linear flexible sealing strips and likewise the outlet 57.
  • the linear flexible sealing strips form chambers where it is possible to recover any gas or air that leaks out and possibly create a different pressure to promote a tight seal.
  • a supply of carbon dioxide is provided to the chamber 50 but is not described herein in that it is per se known to an expert in the field.
  • Carbon dioxide is preferably used in a liquid form, is made to expand outside the chamber 50 and the frigories thus produced are used to cool the water which, by circulating in the cooling calenders, serves to bring the bubble fihn web produced to the temperature of use.
  • the chamber 50 with the appropriate variants can also be used to produce sheets as described above with reference to Figures 3 and 4.
  • the above described embodiment refers to a machine wherein heating of the webs of plastic film is achieved by heating the rolls 53, 54 with oil, flame, steam and/or electrical resistors.

Abstract

Cette invention concerne un nouveau matériau isolant avec des espaces remplis de dioxyde de carbone. Dans un mode de réalisation en particulier, ce matériau comprend une feuille faite d'un film de plastique à bulles dont les bulles sont sensiblement remplies de dioxyde de carbone. Cette feuille s'obtient par réunion d'au moins deux voiles de film plastique dont l'un au moins est de type classique et est réalisé avec des bulles dans une chambre à atmosphère de dioxyde de carbone chambre isolée de l'extérieur. Cette chambre comporte une pluralité de bandes d'étanchéité à l'entrée et à la sortie du film qui empêche le CO2 de fuir et qui forment des chambres dans lesquelles sont récupérées les fuites et qui créent d'éventuelles différences de pression.
