The present invention also provides any and be equipped with at least a conductor element that extends at least a insulation component, and is equipped with at least a electric power and/or communication cable by the sheath of making by the crosslinked material of above-mentioned hydrosilylation method (sheath).
Other characteristic of the present invention and advantage manifest from following description, and this description provides by nonrestrictive illustrative embodiment.
The preparation masterbatch
In this embodiment, the polymeric matrix that constitutes masterbatch is that terpolymer by ethene, propylene and norbornylene constitutes.
Hydrosilylation catalysts based on platinum is the form that chlordene closes platinic acid, and it has formula H 2PtCl 6.xH 2O, and comprise 41.88% pure elements platinum.
The first prepared product A is incorporated in the 36g polymkeric substance by 1g (gram) chlordene is closed platinic acid, promptly with the polymkeric substance of 36 weight parts to the ratio of the catalyzer of 1 weight part and prepare.
Particularly, the sort of operation is carried out in Banbury mixer, to guarantee the good distribution of hydrosilylation catalysts in polymeric matrix.The melt temperature of a little higher than ethylene-propylene-norbornene terpolymer of temperature that is applied, promptly 110 ℃.
Therefore, the prepared product A that obtains by that way contains 1.13% pure platinum.Thereby the second prepared product B is by 1g prepared product A and this terpolymer of 36g, with the similar ratio of the ratio that is used for described first mixture, promptly the polymkeric substance of 36 weight parts is to the prepared product A preparation of 1 weight part.
Described second operation reasonably (logically) is undertaken by using the condition identical with above-mentioned those conditions.Thereby obtain 0.03% active platinum content for prepared product B, therefore prepared product B advantageously constitutes according to masterbatch of the present invention,, is suitable as hydrosilylation catalysts that is.
The preparation insulating material
In temperature remains on 110 ℃ Banbury mixer, at first introduce the base polymer of 100 weight parts, advantageously the base polymer with masterbatch is identical in this embodiment for this base polymer, is ethylene-propylene-norbornene terpolymer.
The unit of above-mentioned amount is weight part/100 part base polymers (pph).
In case this polymkeric substance melts, just introduce silane compound therein, this compound is the form of two kinds of mixture of ingredients.Therefore, add following material: at first be the poly-hydrogenated methyl siloxanes of 3 weight parts, its have along its chain-the SiH-group, hereinafter referred to as " Silox1 "; Next is the poly-hydrogenated methyl siloxanes of 3 weight parts, and its end at its chain contains-the SiH-group, hereinafter referred to as " Silox2 ".
Introduce hydrosilylation catalysts with the form of masterbatch (particularly being prepared product B) again then, make the solid-state platinum content in the gained mixture be positioned at the scope of 12ppm-35ppm, preferably in the scope of 12ppm-20ppm.
Described mixture is hereinafter referred to as " final mixture ".
Married operation carries out 2 minutes time under 125 ℃ temperature.
After this, after that operation, this final mixture self-crosslinking in ambient air.
Good crosslinked in order to confirm by using the method according to this invention to obtain really, use NFEN 60811-2-1 standard and carry out thermal creep under mechanical stress and measure.
Thermal creep test is the end that the weight that will be equivalent to apply the equivalent stress of 0.2 megapascal (MPa) (MPa) is applied to the dumbbell shape sample, and places the stove that is heated to 200 ± 1 ℃ to reach 15 minutes time in this device.
If this sample breaks, think that then the result of this test fails under the combined action of mechanical stress and temperature in test process.
Final mixture with the composition shown in the table 1 is carried out creep test.

The fate of self-crosslinking 20 5 1 -
Thermal creep Sample breaks Do not break Do not break -
Described " fate of self-crosslinking " corresponding to for guaranteeing the sample required minimum fate that do not break, except when beyond can not taking place when crosslinked, this from the sample of final mixture 1 as can be seen.
After 20 days self-crosslinking, the sample of final mixture 1 makes creep test failure, because it breaks during it is arranged in 15 minutes of stove.
Therefore, the amount of employed catalyzer is 10ppm in final mixture 1 promptly, is not enough to make that final mixture has good creep properties.
Different with the sample made from final mixture 1, the sample made from final mixture 2 and 3 under mechanical stress, shows extraordinary thermal creep characteristic after the self-crosslinking of very fast (promptly being less than 7 days).
At last, the sample made from final mixture 4 can not carry out creep test, causes too fast and out of contior reaction kinetics because introduce catalysis masterbatch (the prepared product B with active platinum of 0.03%) in the hot mixt of undersaturated base polymer and silane compound.
As a result, for final mixture, the quantity of the key that is produced becomes too big and can not keep is deformable.
Therefore, it is impossible continuing to stir, because it makes it degraded by the splitting of chain that makes final mixture.
Therefore, for the solid-state platinum content more than or equal to 36ppm, final mixture is obsolete and therefore can not moulding.
The invention is not restricted to the foregoing description, and the method that all can be imagined based on the describe, in general terms that is provided in the specification sheets of the present invention is provided more widely.
