Abstract

Method for assembling a superinsulating material being in the form of plies and formed from at least one very thin metallised perforated polyester sheet 1 which constitutes a screen and from at least one thin polyester tulle fabric which constitutes a separator 3, characterised in that it consists in making, through the screen and the separator, perforations 5 with the aid of a heating tool so as to produce a weld between the screen and the separator along the edge of the perforations.

Description

L'invention vise des matériaux de super isolation qui sont notamment utilisés dans des réservoirs cryogéniques. The invention relates to super-insulation materials which are used in particular in cryogenic tanks.

De tels matériaux comprennent une feuille très mince métallisée et perforée de polyester qui constitue un écran réfléchissant et un séparateur constitué d'un tulle mince de polyester. Généralement la feuille et le tulle sont rendus solidaires par l'un de leur bord. Une telle disposition est peu pratique, car le matériau tend à plisser, surtout s'il s'agit de nappes ayant des dimensions importantes.Such materials include a very thin metallized and perforated polyester sheet which constitutes a reflecting screen and a separator made of a thin polyester tulle. Generally the sheet and the tulle are made integral by one of their edge. Such an arrangement is impractical, because the material tends to wrinkle, especially if it is plies having large dimensions.

L'un des buts de la présente invention est de remédier à cet inconvénient. One of the aims of the present invention is to remedy this drawback.

Le procédé, selon l'invention vise l'assemblage d'un matériau super isolant se présentant en nappes et formé d'au moins une feuille perforée très mince métallisée de ployester qui constitue un écran et d'au moins un tulle mince de polyester qui constitue un séparateur et est caractérisé en ce qu'il consiste à pratiquer au travers de l'écran et du séparateur des perforations à l'aide d'un outil chauffant de manière à réaliser entre l'écran et le séparateur le long du bord des perforations, une soudure. The method according to the invention relates to the assembly of a super-insulating material in layers and formed of at least one very thin perforated sheet of metallized ployester which constitutes a screen and of at least one thin polyester tulle which constitutes a separator and is characterized in that it consists in practicing through the screen and the separator perforations using a heating tool so as to produce between the screen and the separator along the edge of the perforations, a weld.

Ainsi on obtient un matériau qui ne plisse pas et qui est plus facile à utiliser. This produces a material that does not wrinkle and is easier to use.

Lorsqu'on utilise le matériau formé d'un empilage d'écrans et de séparateurs correspondants, afin d'éviter les ponts thermiques on réalise les perforations à l'aide de l'outil chauffant, décalées dans l'épaisseur du matériau.  When using the material formed by a stack of screens and corresponding separators, in order to avoid thermal bridges, the perforations are made using the heating tool, offset in the thickness of the material.

L'invention va maintenant être décrite avec plus de détails en se référant à des modes de réalisation particuliers donnés à titre d'exemple seulement et représentés au dessins annexés, dans lesquels
Figure 1 est une vue en perspective montrant un matériau isolant en nappe.The invention will now be described in more detail with reference to particular embodiments given by way of example only and shown in the accompanying drawings, in which
Figure 1 is a perspective view showing an insulating sheet material.

Figure 2 est une vue en coupe. Figure 2 is a sectional view.

Le matériau isolant représenté à la figure 1 comprend une feuille très mince 1 de polyester métallisée pourvue de perforations 2 et constituant un écran et un tulle mince de polyester 3 constituant un séparateur. The insulating material shown in FIG. 1 comprises a very thin sheet 1 of metallized polyester provided with perforations 2 and constituting a screen and a thin polyester tulle 3 constituting a separator.

Pour réaliser l'assemblage entre l'écran et le tulle, on perfore de place en place ces deux éléments avec un outil chauffant pour réaliser ainsi une soudure le long du bord des perforations 5. To make the assembly between the screen and the tulle, these two elements are punctured from place to place with a heating tool to thus achieve a weld along the edge of the perforations 5.

On peut également réaliser comme cela est représenté à la figure 2 l'assemblage de tout une série de nappes formées de plusieurs écrans 1 entre lesquels sont insérés les séparateurs 3, ces ensembles étant perforés avec un outil chauffant de manière qu'ils soient solidarisés le long des bords des perforations 5. It is also possible, as shown in FIG. 2, to assemble a whole series of plies formed of several screens 1 between which the separators 3 are inserted, these assemblies being perforated with a heating tool so that they are secured together. along the edges of the perforations 5.

On peut aussi prévoir lorsqu'on utilise un grand nombre de nappes d'écrans 1 et de séparateurs 3 que les perforations soients décalées dans l'épaisseur de l'ensemble des nappes pour éviter la formation de ponts thermiques trop importants. Ainsi, si on suppose que le matériau comprend dix écrans superposés l avec des séparateurs correspondants 3, on pourrait réaliser une première série de perforations pour solidariser les quatre écrans supérieurs et les séparateurs correspondants, une seconde série de perforations 5 pour solidariser les second, troisième, quatrième, cinquième et sixième écrans et les séparateurs correspondants, une troisième série de perforations pour solidariser les quatrième, cinquième, sixième, septième et huitienne écrans et séparateurs et ainsi de suite.  It can also be provided when a large number of screen plies 1 and separators 3 are used that the perforations are offset in the thickness of all of the plies to avoid the formation of excessive thermal bridges. Thus, if it is assumed that the material comprises ten superimposed screens l with corresponding separators 3, one could make a first series of perforations to secure the four upper screens and the corresponding separators, a second series of perforations 5 to secure the second, third , fourth, fifth and sixth screens and the corresponding separators, a third series of perforations for securing the fourth, fifth, sixth, seventh and eighth screens and separators and so on.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation qui viennent d'être décrits et représentés. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.  Of course, the invention is not limited to the embodiments which have just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
