Definitions
- the present invention relates to a hydrosilylation process which is particularly intended for the preparation of a crosslinkable polymeric composition.
- the invention finds a particularly advantageous, but not exclusive, application in the field of insulation and / or sheathing materials for energy and / or telecommunication cables, including optical fiber cables.
- Hydrosilylation is a grafting process that is widely used today, particularly in the manufacture of silicones. It consists schematically in grafting a silane compound onto an unsaturated polymer, with the objective of obtaining a potentially crosslinkable polymeric composition.
- hydrosilylation is generally carried out by mixing an unsaturated polymer with a silane compound, all in the presence of a platinum-based hydrosilylation catalyst.
- the polymer is usually used in solid form, while the silane compound and the platinum catalyst are commonly employed in liquid form.
- This type of process has the disadvantage of being difficult to transpose to the field of cabling, since the substances used in the formulation are predominantly in liquid form. Indeed, cable manufacturing equipment, including extruders, are generally adapted to be powered and then operate essentially with purely solid materials.
- Such a hydrosilylation process also has the disadvantage of being extremely expensive, mainly because of the intrinsic cost of the liquid platinum catalyst. This is all the more true that the catalyst in question must necessarily be used in large quantities to obtain somewhat uniform results.
- the technical problem to be solved by the object of the present invention is to provide a hydrosilylation process consisting of mixing an unsaturated base polymer, a silane compound and a platinum hydrosilylation catalyst constituted by a masterbatch consisting of a polymer matrix in which solid platinum is dispersed, a hydrosilylation process which makes it possible to avoid the problems of the state of the art, in particular by offering an optimal match with the means of production of the cable, while being substantially less expensive.
- the basic unsaturated polymer may be of any known nature, and in particular an olefin.
- the silane compound relates very generally to any substance having silicon-hydrogen bonds Si-H.
- the invention as thus defined has the advantage of being perfectly compatible with existing cable manufacturing equipment, and in particular extruders. Indeed, provided that the silane compound generally liquid is beforehand Amalgamated with the conventionally solid unsaturated polymer, it is possible to mix with the platinum catalyst, with materials that are completely solid initially. The fact of being able to implement the invention directly with the means of production of the cable, constitutes a technical and economic advantage.
- a hydrosilylation catalyst in the form of a masterbatch also allows a better dispersion of platinum within the mixture, resulting in a significantly higher efficiency. Equivalent effect, it is therefore possible to use substantially less catalyst, which implies a significant gain in terms of cost. Another consequence of the decrease of the platinum content in the overall mixture lies in the preservation of the electrical properties of the final material; the latter being then virtually unaffected by the presence of the conductive metal. Finally, the conditioning of the platinum in the form of a masterbatch makes it possible to precisely determine the quantity of catalyst actually necessary, which is fundamental in the context of the invention since its final concentration must be of the order of only a few ppm or parts per million.
- the polymer matrix of the masterbatch is chosen from the group of polyolefins, polyolefin copolymers, or any mixture of these components.
- the nature of the polymer matrix of the masterbatch is identical to that of the unsaturated base polymer. This characteristic makes it possible not to modify the mechanical, dielectric and aging properties of the final material.
- the solid platinum of the masterbatch is constituted by hexachloroplatinic acid.
- the content of hydrosilylation catalyst is between 4 and 7% relative to the total amount of unsaturated base polymer.
- the silane compound is a polyhydrosiloxane, and in particular a polymethylsiloxane.
- the content of silane compound is between 1 and 8% relative to the total amount of unsaturated base polymer, and preferably between 4 and 6%.
- the crosslinking process is carried out at a temperature which is between 100 and 125 ° C.
- the invention also relates to any energy and / or telecommunication cable comprising at least one conductive element extending inside at least one insulating element, and wherein at least one insulating element is made of a crosslinked material. following a hydrosilylation process as previously described.
- the invention is furthermore related to any energy and / or telecommunication cable provided with at least one conductive element extending inside at least one insulating element, and further provided with at least one sheath made of a crosslinked material according to a hydrosilylation process as previously described.
- the polymer matrix composing the masterbatch consists here of terpolymer of ethylene propylene norbornene.
- the platinum-based hydrosilylation catalyst is in the form of a hexachloroplatinic acid of formula H 2 PtCl 2 , xH 2 0, and comprising 41.88% pure platinum element.
- a first preparation A is made by incorporating hexachloroplatinic acid Ig in 36 g of polymer, i.e., in a proportion of 36 parts by weight of polymer to 1 part by weight of catalyst. Concretely, this operation is carried out in an internal mixer in order to guarantee a good dispersion of the hydrosilylation catalyst within the polymer matrix.
- the applied temperature is slightly higher than the melting temperature of the ethylene propylene norbornene terpolymer, ie HO 0 C.
- Preparation A thus obtained then contains 1.13% pure platinum. Since this content is still too important for the intended application, a new dilution operation is carried out.
- a second preparation B is therefore prepared from ig of Preparation A and 36 g of terpolymer, in a proportion similar to that of the first mixture, that is to say 36 parts of polymer weight per 1 part by weight of preparation A.
- This second operation proceeds logically according to the same conditions as those previously described.
- An active platinum content of 0.03% is then obtained for this preparation B which thus advantageously forms a masterbatch according to the invention, that is to say used as a hydrosilylation catalyst.
- a base polymer which is in this example advantageously identical to that of the masterbatch, that is to say the terpolymer of ethylene propylene norbornene.
- silane compound which is here in the form of a mixture of two constituents is then incorporated.
- Siloxl 3 parts by weight of a polymethylhydrosiloxane endowed with groups -SiH- along the chain, hereinafter referred to as "Siloxl”
- Silox2 3 parts by weight of a polymethylhydrosiloxane provided with -SiH- groups at the end of the chain
- the hydrosilylation catalyst is incorporated in its turn, in the form of a masterbatch, in this case Preparation B, so that the solid platinum content of the mixture thus obtained is between 12 and 35 ppm, and preferably between 12 and 20 ppm.
- the mixing operation is carried out at a temperature of 125 ° C. and for a duration of 2 minutes. Then, after this operation, the final mixture self-crosslinks to the ambient air.
- heat creep measurements under mechanical stress were carried out according to standard NF EN 60811-2-1. The hot creep is to ballast one end of a dumbbell type test piece with a mass corresponding to the application of a stress equivalent to 0.2 MPa, and to place the assembly in an oven heated to 200 +/- 1 0 C for a period of 15 minutes.
- test result is then considered as a failure.
- the creep tests are carried out on final mixtures whose compositions are detailed in Table 1.
- the final mixtures 1 to 4 are implemented according to the process described above.
- Table 2 shows the heat-creep results under mechanical stress for final mixtures 1 to 4.
- the "number of days of self-crosslinking" corresponds to the minimum number of days necessary not to break the specimen, except if crosslinking can not take place, as can be seen with the test specimen of the final mixture 1 Indeed, after 20 days of self-crosslinking, the test piece of the final mixture 1 fails the creep test because of its rupture during the 15 minutes of residence in the oven.
- the amount of catalyst used, namely 10 ppm, in the final mixture 1, is therefore not sufficient to provide a final blend with optimized creep properties.
- test pieces of the final mixture 2 and 3 have very good mechanical stress heat creep properties for very fast self-crosslinking, that is to say less than 7 days.
- the final mixture test piece 4 could not undergo the creep test since the incorporation of the catalytic masterbatch (preparation B at 0.03% active platinum) in the hot mixture of unsaturated base polymer with the Silane compounds give rise to reaction kinetics that are too fast to be controlled. As a result, the number of links created becomes too great for the final mixture to remain transformable.
- the final mixture is unusable and can not be shaped.
- the present invention is not limited to the implementation examples which have just been described and relates in general to all the methods that can be envisaged from the general indications given in the disclosure of the invention.
