Description
MATERIAU THERMOPLASTIQUE EXTRUDABLE ET MICROMODULE DE FIBRE FABRIQUE A PARTIR D'UN TEL MATERIAU La présente invention a pour objet un matériau extrudable permettant de constituer des pellicules de faible épaisseur, comportant un polymère oléfinique. L'invention trouve une application particulièrement importante, bien que non exclusive, dans la constitution de gaines de micromodules de fibres optiques gainées incorporables dans un câble tel que celui décrit dans le document EP-A-0 468 878 auquel on pourra se reporter. The present invention relates to an extrudable material for constituting films of small thickness, comprising an olefinic polymer. EXTRUDABLE THERMOPLASTIC MATERIAL AND FIBER MICROMODULE MADE THEREFROM The invention finds a particularly important, although not exclusive, application in the constitution of sheaths of micromodules of sheathed optical fibers that can be incorporated in a cable such as that described in document EP-A-0 468 878 to which reference may be made.
Pour un certain nombre d'applications, et notamment pour la constitution de micromodules ayant un faisceau de fibres optiques gainées en contact mutuel, enfermé avec un gel d'étanchéité dans une enveloppe de maintien extrudée, est souhaitable de remplir des conditions qui sont dans une certaine mesure contradictoires. Par exemple, on recherche souvent à la fois, notamment dans le de la constitution de micromodules - une aptitude à l'extrusion en pellicule mince (si possible vers 0,1 mm), - la compatibilité du matériau avec les gels habituels d'étanchéité, - une résistance suffisante du matériau mis sous forme de pellicule mince, afin de permettre une manipulation au cours d'opérations ultérieures sans risque de déchirure, - l'absence de collage de la pellicule de gaine du micromodule sur les fibres, lors du chauffage qui intervient du fait de la mise en place de l'enveloppe extérieure en matériau thermoplastique, - le maintien d'une cylindricité correcte lors de la fabrication du micromodule de l'assemblage des micromodules pour constituer un câble, - retrait réduit au cours de l'extrusion de la gaine pour constituer le micromodule, et cours du refroidissement, cela pour éviter des contraintes sur les fibres optiques, - coloration aisée du matériau, permettant d'identifier les micromodules, - extensibilité limitée permettant de dénuder facilement un micromodule afin de préparer les extrémités pour raccorder les fibres, - enfin, une résistance élevée aux produits chimiques utilisés lors des opérations effectuées sur les câbles, par exemple au solvant de nettoyage. For a number of applications, and especially for the constitution of micromodules having a bundle of optical fibers sheathed in mutual contact, enclosed with a sealing gel in an extruded holding envelope, is desirable to fulfill conditions which are in a certain contradictory measures. For example, it is often sought at the same time, in particular in the constitution of micromodules - an aptitude for thin film extrusion (if possible to about 0.1 mm), - the compatibility of the material with the usual gels of sealing - sufficient strength of the material in thin film form, to allow handling in subsequent operations without risk of tearing, - the lack of gluing of the micromodule sheath film on the fibers, during heating which intervenes because of the establishment of the outer shell of thermoplastic material, - the maintenance of a correct cylindricity during the manufacture of the micromodule of the assembly of micromodules to form a cable, - reduced shrinkage during the extrusion of the sheath to form the micromodule, and cooling course, to avoid constraints on the optical fibers, - easy coloring of the material, allowing iden - limited extensibility for easily stripping a micromodule in order to prepare the ends for connecting the fibers, - finally, a high resistance to the chemicals used during the operations performed on the cables, for example to the cleaning solvent.
Dans le cas de la fabrication de câbles à fibres optiques, certaines des caractéristiques ci-dessus sont essentielles, notamment la résistance mécanique, y compris lors du vieillissement thermique, et la compatibilité avec les gels d'étanchéité et les solvants de nettoyage utilisés pour éliminer le gel et les salissures avant d'effectuer raccordement des fibres optiques à un connecteur. Mais la résistance mécanique est défavorable à la commodité d'emploi, car une pellicule de gainage résistante et ayant grand allongement avant rupture gêne le dénudage des micromodules pour libérer I parties terminales des fibres. In the case of fiber optic cable manufacturing, some of the above features are essential, including mechanical strength, including thermal aging, and compatibility with sealing gels and cleaning solvents used to eliminate freezing and soiling before connecting the optical fibers to a connector. However, the mechanical strength is unfavorable to the convenience of use, since a strong cladding film having a large elongation before failure hinders the stripping of the micromodules to release the end portions of the fibers.
La présente invention vise notamment à fournir un matériau extrudable en pellicule fine représentant un compromis satisfaisant entre les différents résultats à atteindre. L'invention propose notamment dans ce but un matériau extrudable en pellicule fine, constitué par une composition contenant un polymère oléfinique et un taux de charges compris entre 25 à 65 1o en poids de la composition, ledit matériau à l'état non divisé ayant une résistance à la traction comprise entre 6 et 20 Mpa et un allongement à la rupture compris entre 50 et 300 %. The present invention aims in particular to provide an extrudable material in thin film representing a satisfactory compromise between the different results to be achieved. For this purpose, the invention proposes an extrudable fine-film material consisting of a composition containing an olefinic polymer and a filler content of between 25 to 65% by weight of the composition, said material in the undivided state having a tensile strength of between 6 and 20 MPa and an elongation at break of between 50 and 300%.
La dureté shore du matériau est avantageusement comprise entre 35 et 55 D. Grâce à l'allongement limité à la rupture, dû notamment à la présence de charges, la dénudabilité est suffisante pour ne pas obliger à avoir recours à des outils spéciaux. Les caractéristiques minimales ci-dessus, notamment la résistance à traction et l'allongement à la rupture, évitent une fragilité excessive du matériau lors la manipulation. En particulier, ces minima permettent des manipulations lors de fabrication d'un câble ou des raccordements sans risques excessifs de dommages. The shore hardness of the material is advantageously between 35 and 55 D. Due to the elongation limited to failure, due in particular to the presence of loads, the stripping is sufficient not to require the use of special tools. The above minimum characteristics, including tensile strength and elongation at break, prevent excessive brittleness of the material during handling. In particular, these minima allow manipulation during manufacture of a cable or connections without excessive risk of damage.
De plus, le choix d'une dureté Shore D dépassant 35 permet, en cas d'utilisation du matériau pour constituer une gaine de micromodule, d'assurer une cylindricité satisfaisante et d'éviter l'effet dit "de paille", constituée par la formation d'un coude brutal lors des flexions nécessaires à la réalisation des raccordements. In addition, the choice of a Shore D hardness in excess of 35 makes it possible, in case of use of the material to form a micromodule sheath, to ensure satisfactory cylindricity and to avoid the so-called "straw effect" formed by the formation of a brutal bend during the bending necessary to make the connections.
La teneur minimale en charges indiquée plus haut permet de réduire la dilatation et la rétraction des matériaux lors des variations de température qui interviennent lors la fabrication d'un câble. La présence d'une teneur suffisante de charges permet d'eviter le risque de collage des micromodules entre eux, sur des fibres gainées ou sur enveloppe externe. The minimum filler content indicated above makes it possible to reduce the expansion and shrinkage of the materials during the temperature variations that occur during the manufacture of a cable. The presence of a sufficient content of the charges makes it possible to avoid the risk of gluing the micromodules together, on sheathed fibers or on an outer envelope.
Les charges seront généralement minérales. On peut notamment utiliser l'alumine (hydratée ou non), la craie, le kaolin, le talc, la silice, l'hydroxyde de magnésie et leurs mélanges. Toutes ces charges réduisent l'allongement à la rupture et la dilatation ou la rétraction lors des variations de température. Au surplus, elles augmentent l'inertie thermique. Charges will generally be mineral. It may especially be used alumina (hydrated or not), chalk, kaolin, talc, silica, magnesia hydroxide and mixtures thereof. All of these fillers reduce elongation at break and expansion or retraction during temperature changes. Moreover, they increase the thermal inertia.
Les polymères oléfiniques utilisables sont sensiblement les mêmes que ceux couramment utilisés à l'heure actuelle. En particulier, on peut citer les produits suivants - : polyéthylènes - : polypropylènes - : Ethylène Propylène Rubber (Caoutchouc d'ethylène propylène) - EPDM : Ethylène propylène Diène Monomère - : copolymères ethylène-acétate d'alkyl inférieur ( notamment acétate de vinyl) - : copolymères éthylène - acrylate d'alkyl inférieur (notamment acrylate de methyl, éthyl et surtout butyl) - : Ethylène Ethyl Acrylate - VLDPE : Very Low Density Polyethylène (polyethylène à très basse densité) - polymères greffés d'acide acrylique ou d'anhydride maléique - PVC : chlorure de polyvinyl - leurs mélanges et copolymères. The olefinic polymers that can be used are substantially the same as those currently in use. In particular, mention may be made of the following products: polyethylenes: polypropylenes: Ethylene Propylene Rubber (ethylene propylene rubber) EPDM: Ethylene propylene Diene monomer: ethylene-lower alkyl acetate copolymers (especially vinyl acetate) -: ethylene-lower alkyl acrylate copolymers (in particular methyl acrylate, ethyl and especially butyl) -: Ethylene Ethyl Acrylate - VLDPE: Very Low Density Polyethylene (very low density polyethylene) - graft polymers of acrylic acid or of maleic anhydride - PVC: polyvinyl chloride - their mixtures and copolymers.
Le matériau extrudable comportera généralement de plus des plastifiants à faible teneur,ne dépassant pas quelques pour cent en poids, tels des huiles aliphatiques ou des phtalates (par exemple phtalate de di-octyle ou didécyle), des adipates, des trimellitates, etc. Des produits de protection contre chaleur ou les ultraviolets doivent être incorporés lorsqu'une exposition ou le rayonnement solaire est à craindre. The extrudable material will generally further include low-content plasticizers, not exceeding a few percent by weight, such as aliphatic oils or phthalates (eg, di-octyl phthalate or didecyl), adipates, trimellitates, and the like. Heat or ultraviolet protection products must be incorporated when exposure or solar radiation is to be expected.
Dans certains cas, on ajoutera un ou des silanes ou aminosilanes, tels que - vinyl trimethoxysilane - amino propylsilane - amino trimethoxysilane Si on utilise un trialkoxy silane, il sera souhaitable de. ne pas aller au-delà d'un composé ayant plus de cinq atomes de carbone. In some cases, one or more silanes or aminosilanes, such as - vinyl trimethoxysilane - amino propylsilane - amino trimethoxysilane, may be added. If a trialkoxy silane is used, it will be desirable to. do not go beyond a compound with more than five carbon atoms.
On donnera maintenant, à titre d'exemple, les propriétés de plusieurs matériaux conformes à l'invention, en même temps qu'une comparaison avec un matériau témoin classiquement utilisé à ce jour pour constituer une gaine de micromodule. La description qui suit fait référence à la figure unique qui montre un micromodule dans un état déformé qu'il est susceptible de prendre lorsqu'il est pressé contre d'autres micromodules par une enveloppe externe. Le micromodule comporte plusieurs fibres optiques 10 individuellement gainées contenues dans une gaine 12 qui doit etre facilement déchirable pour permettre le dénudage des extrémités des fibres en de raccordements. Cette gaine 12 est généralement constituée par extrusion le faisceau de fibres optiques 10 lors du tirage de ces dernières et prend alors une forme approximativement circulaire lorsque le faisceau de fibres présente lui même un pourtour dont la forme ne s'écarte pas trop du cercle corconscrit. La gaine enserre les fibres et s'applique en effet contre elles. A l'intérieur d'un câble, la pression des micromodules les uns contre les autres peut déformer leurs section et les amener par exemple a celle qui est illustrée. By way of example, the properties of several materials in accordance with the invention will now be given at the same time as a comparison with a control material conventionally used to date to form a micromodule sheath. The following description refers to the single figure which shows a micromodule in a deformed state that it is likely to take when pressed against other micromodules by an outer envelope. The micromodule comprises a plurality of individually sheathed optical fibers 10 contained in a sheath 12 which must be easily tearable to allow stripping of the ends of the fibers into connections. This sheath 12 is generally formed by extruding the bundle of optical fibers 10 during the drawing of the latter and then takes an approximately circular shape when the bundle of fibers itself has a periphery whose shape does not deviate too much from the cortex circle. The sheath grips the fibers and applies against them. Inside a cable, the pressure of the micromodules against each other can deform their section and bring them for example to that which is illustrated.
matériau témoin est constitué par du polyéthylène ayant une densité nominale 0,92 et un "melt flow index" de 0,3 g110 mn à 190 C, sous une pression de 21,6 N. matériau a été utilisé pour constituer la gaine d'un micromodule, par extrusion sur un faisceau de quatre fibres optiques. La gaine 12 constituée avait un diamètre de 1 mm et une épaisseur de 0,12 mm. L'extrusion se fait sans difficulté et la gaine obtenue est bien cylindrique. Mais lors de la constitution du câblé, par extrusion d'une enveloppe externe à base de polyéthylène, la chaleur nécessaire à l'extrusion de l'enveloppe déforme les micromodules et les gaines tendent à se coller ensemble et à se coller à l'enveloppe extérieure, imposant des précautions particulières, comme exemple l'interposition d'un ou plusieurs rubans séparateurs entre les micromodules l'enveloppe. The control material consists of polyethylene having a nominal density of 0.92 and a "melt flow index" of 0.3 g / min at 190 ° C., under a pressure of 21.6 N. Material was used to form the sheath. a micromodule, by extrusion on a bundle of four optical fibers. The sheath 12 constituted had a diameter of 1 mm and a thickness of 0.12 mm. The extrusion is done without difficulty and the sheath obtained is cylindrical. But during the constitution of the cord, by extrusion of an outer envelope based on polyethylene, the heat required for the extrusion of the envelope deforms the micromodules and sheaths tend to stick together and to stick to the envelope external, imposing special precautions, as an example the interposition of one or more separator tapes between the micromodules envelope.
Ces difficultés sont écartées lors de la mise en ceuvre d'un matériau conforme l'invention. These difficulties are eliminated during the implementation of a material according to the invention.
<U>Exemple 1</U> Dans un mélangeur, on a préparé une composition comprenant, en poids - 50 parts de polyethylène de densité 0,92 ayant un Melt Flow Index à 190 C, sous 21 N, de 1.8g110 min - 50 parts de copolymère EVA contenent 18 % d'acétate de vinyle -130 parts d'hydrate d'alumine - 5 parts de lubrifiant (huile paraffinique) - 5 parts d'additifs (anti-oxydants, silane, lubrifiant) Les ingrédients sont mélangés pendant 10 minutes, jusqu'à 160 C. <U> Example 1 </ U> In a mixer, there was prepared a composition comprising, by weight - 50 parts of polyethylene of density 0.92 having a Melt Flow Index at 190 C, under 21 N, 1.8 g / min - 50 parts of EVA copolymer contains 18% of vinyl acetate -130 parts of alumina hydrate - 5 parts of lubricant (paraffinic oil) - 5 parts of additives (anti-oxidants, silane, lubricant) The ingredients are mixed for 10 minutes, up to 160 C.
Après calandrage sur un mélangeur à cylindres, le materiau est découpé, puis moulé à 180 C sous pression, sous forme de plaques permettant d'effectuer des mesures caractérisant le matériau. After calendering on a roll mill, the material is cut and then molded at 180 ° C. under pressure, in the form of plates making it possible to carry out measurements characterizing the material.
Les caractéristiques mécaniques obtenues sur les plaques sont les suivantes Résistance à la rupture = 11.4 Mpa Allongement à la rupture = 125 Dureté = 45 Shore D La composition a été utilisée pour constituer des micromodules. Pour cela, on l'a mise sous forme de granulés qui sont introduits dans une extrudeuse de 45 mm de diamètre, et 24 diamètres de longueur. The mechanical characteristics obtained on the plates are the following: Resistance to fracture = 11.4 MPa Elongation at break = 125 Hardness = 45 Shore D The composition was used to constitute micromodules. For this, it was put in the form of granules which are introduced into an extruder 45 mm in diameter, and 24 diameters in length.
Les températures d'extrusion sont comprises entre 130 et 165 C, depuis la trémie d'alimentation, jusqu'à la tête d'extrusion. The extrusion temperatures are between 130 and 165 C, from the feed hopper, to the extrusion head.
Pour caractériser la gaine obtenue, deux opérations ont eté faites. To characterize the sheath obtained, two operations were made.
La première a été une mise en forme à une vitesse de OOmlmin, pour obtenir un tube de 0 mm de diamètre externe, et de 0.12 mm d'épaisseur radiale. The first was a shaping at a speed of OOmlmin, to obtain a tube of 0 mm in outer diameter, and 0.12 mm in radial thickness.
Pour seconde, la mise en forme a été identique à cela près qu'on introduit à travers la tête l'extrudeuse 4 fibres optiques colorées, et qu' injecte simultanément un gel d'étanchéité pour former un module qui, après refroidissement de la matière extrudée, est recueilli dans un bac où il s'enroule librement à plat. For second, the shaping was identical except that we introduce through the head extruder 4 colored optical fibers, and that simultaneously injects a sealing gel to form a module which, after cooling of the material extruded, is collected in a tray where it winds freely flat.
