Description
L'invention concerne l'utilisation d'une feuille d'aluminium pour ignifuger une pièce comprenant une structure à base de matière plastique et une pièce issue d'une telle utilisation. The invention relates to the use of an aluminum foil for flame retarding a part comprising a plastic-based structure and a part resulting from such use.
II est connu d'utiliser des agents ignifugeant, par exemple à base de composés halogénés, pour ignifuger une pièce comprenant une structure à base de matière plastique, ladite pièce étant notamment destinée à être montée dans un véhicule automobile. It is known to use flameproofing agents, for example based on halogenated compounds, for fireproofing a part comprising a structure based on plastics material, said part being in particular intended to be mounted in a motor vehicle.
L'utilisation de ces agents est très coûteuse. L'invention a pour but de pallier cet inconvénient. The use of these agents is very expensive. The invention aims to overcome this disadvantage.
A cet effet, et selon un premier aspect, l'invention propose l'utilisation d'une feuille d'aluminium pour ignifuger une pièce comprenant une structure à base de matière plastique, ladite feuille étant associée à tout ou partie d'au moins une face de ladite structure. For this purpose, and according to a first aspect, the invention proposes the use of an aluminum foil for fireproofing a part comprising a structure based on a plastic material, said sheet being associated with all or part of at least one face of said structure.
La demanderesse a constaté, de façon inattendue, qu'une pièce ainsi agencée présente des performances anti-feu équivalentes à celles obtenues par l'emploi d'agents ignifugeants, et notamment d'obtenir une classification de type B pour ladite pièce, sur laquelle la combustion est ralentie. The Applicant has found, unexpectedly, that a piece thus arranged has fire performance equivalent to those obtained by the use of flame retardants, and in particular to obtain a type B classification for said piece, on which combustion is slowed down.
Le faible coût d'une telle feuille d'aluminium permet de réduire de façon drastique le coût de l'ignifugation de la pièce. The low cost of such aluminum foil drastically reduces the cost of fireproofing the part.
Selon un deuxième aspect, l'invention propose une pièce issue d'une telle utilisation. According to a second aspect, the invention proposes a part resulting from such use.
D'autres particularités et avantages de l'invention apparaîtront dans la description qui suit, faite en référence à la figure jointe qui est une représentation schématique en coupe d'une pièce issue de l'utilisation sus mentionnée. Other features and advantages of the invention will appear in the description which follows, made with reference to the attached figure which is a schematic sectional representation of a part resulting from the aforementioned use.
En référence à la figure, on décrit l'utilisation d'une feuille 1 d'aluminium pour ignifuger une pièce 2 comprenant une structure 3 à base de matière plastique, par exemple à base de polypropylène, ladite feuille étant associée à tout ou partie d'au moins une face, ici une seule face, de ladite structure. Referring to the figure, the use of an aluminum foil 1 to flameproof a part 2 comprising a structure 3 based on plastic, for example based on polypropylene, said sheet being associated with all or part of at least one face, here only one face, of said structure.
Selon une réalisation, la feuille 1 est associée par surmoulage à la structure 3 qui est moulée. According to one embodiment, the sheet 1 is associated by overmolding to the structure 3 which is molded.
On décrit à présent une pièce 2 ignifugée, issue d'une telle utilisation, comprenant une structure 3 à base de matière plastique dont au moins une face est, en tout ou partie, associée à une feuille 1 d'aluminium. We now describe a fireproofed part 2, resulting from such use, comprising a structure 3 based on plastic material, at least one side is, in whole or part, associated with a sheet 1 of aluminum.
On remarquera que la feuille 1 d'aluminium a aussi des propriétés de réflexion de la chaleur, ce qui peut conférer à la pièce 2 des propriétés de protection thermique. It will be noted that the aluminum foil 1 also has heat-reflecting properties, which can give the component 2 thermal protection properties.
Selon une réalisation, la feuille 1 d'aluminium présente une épaisseur comprise entre 50 et 200 microns, notamment entre 50 et 100 microns. Selon une réalisation, la feuille 1 est associée par surmoulage à la structure 3 qui est moulée. Elle est disposée dans le moule et prend la forme de la pièce 2 sous l'effet de la pression de la matière plastique injectée. According to one embodiment, the aluminum sheet 1 has a thickness of between 50 and 200 microns, especially between 50 and 100 microns. According to one embodiment, the sheet 1 is associated by overmolding to the structure 3 which is molded. It is arranged in the mold and takes the form of the part 2 under the effect of the pressure of the injected plastic material.
25 Selon une réalisation non représentée, la structure 3 est en forme de récipient, notamment de sorte à former bac de batterie ou boite à eau de véhicule automobile, la feuille 1 étant associée à la face externe de ladite structure. According to an embodiment not shown, the structure 3 is in the form of a container, in particular so as to form battery tray or water box motor vehicle, the sheet 1 being associated with the outer face of said structure.
Selon la réalisation représentée, la structure 3 est sous forme d'écran 30 thermique et/ou acoustique et/ou aérodynamique, notamment de sorte à former écran sur moteur, écran de tunnel ou écran de déflection d'air de véhicule automobile.20 Dans un tel écran, on peut prévoir, comme représenté sur la figure, qu'une face de la structure 3, opposée à une face associée à une feuille 1 d'aluminium, est associée à une couche poreuse 4 d'absorption acoustique. According to the embodiment shown, the structure 3 is in the form of a thermal and / or acoustic and / or aerodynamic screen, in particular so as to form a screen on an engine, a tunnel screen or a motor vehicle air deflection screen. such a screen, it can be provided, as shown in the figure, a face of the structure 3, opposite a face associated with a sheet 1 of aluminum, is associated with a porous layer 4 sound absorption.
Dans la réalisation représentée, la couche poreuse 4 est associée, sur sa face externe, à une feuille d'aluminium micro-perforée 5 de protection aux fluides. In the embodiment shown, the porous layer 4 is associated, on its outer face, with a micro-perforated aluminum foil 5 for protecting the fluids.
La taille des perforations 6 est agencée de sorte à empêcher une pénétration des fluides, tels que l'essence ou l'huile, tout en permettant une traversée des ondes sonores pour permettre leur absorption dans la couche poreuse 4. The size of the perforations 6 is arranged so as to prevent the penetration of fluids, such as gasoline or oil, while allowing sound waves to pass through to allow their absorption in the porous layer 4.
Selon une réalisation, la feuille micro-perforée 5 présente une épaisseur comprise entre 70 et 130 microns, notamment de l'ordre de 100 microns. According to one embodiment, the micro-perforated sheet 5 has a thickness between 70 and 130 microns, in particular of the order of 100 microns.
Selon une réalisation, la feuille micro-perforée 5 présente une densité de perforations 6 comprise entre 400 000 et 600 000 perforations /m2, notamment de l'ordre de 500 000 perforations /m2. According to one embodiment, the micro-perforated sheet 5 has a perforation density 6 of between 400,000 and 600,000 perforations / m 2, in particular of the order of 500,000 perforations / m 2.
Selon une réalisation non représentée, on peut prévoir que la structure 3 est poreuse, par exemple en étant à base de feutre de polypropylène comprimé, ce qui évite l'utilisation d'une couche poreuse 4. Dans ce cas aussi on peut prévoir de disposer une feuille micro-perforée 5 à l'opposé de la feuille 1 d'aluminium. According to an embodiment not shown, it can be provided that the structure 3 is porous, for example by being based on compressed polypropylene felt, which avoids the use of a porous layer 4. In this case also it is possible to provide a micro-perforated sheet 5 opposite the foil 1 of aluminum.
