Definitions
- the invention relates to a filling compound for an elongated optical transmission element which contains at least one optical waveguide.
- a filler for optical transmission elements is known from EP 029 198 B1, which consists of a mixture of an oil, a thixotropic agent and additionally contains an organic thickener which consists entirely or partially of halogenated and / or halogen-free hydrocarbon polymers . Further filling materials also containing oils are described in DE 38 39 596 A1 and US Pat. No. 4,701016. From DE-OS 27 28 642 a longitudinally watertight optical waveguide cable is known, in which swollen polystyrene in oil is used as a wire filling compound.
- the requirements for such wire filling compounds are that the optical fibers are not subjected to any impermissible tensile and / or compressive forces, ie that the filling compound must not be too stiff. Since this should also apply at relatively low temperatures, for example -30.degree., The oils used have to meet particularly stringent requirements so that they do not harden too much at the low temperatures. Furthermore, these fillings should be sufficiently safe against dripping be (drain test), which is a critical requirement especially at higher temperatures. By using the thixotropic agents in the known wire filling compounds, the behavior can be influenced favorably, especially at higher temperatures, to which the use of thickeners also contributes.
- the invention has for its object to provide a filling material that is particularly economical to produce. This object is achieved according to the invention in a filling compound of the type mentioned at the outset in that the filling compound has a proportion in the form of a plasticizer.
- plasticizers are relatively inexpensive because they are used on a large scale in chemistry. They also have the advantage that they are largely indifferent, in particular e.g. Do not attack or impair protective sleeves or cable jackets. Such plasticizers are particularly easy to process, have a low vapor pressure and are mostly odorless, colorless and generally also light, cold and heat resistant. Another advantage of the plasticizers is that they are not hygroscopic, which is particularly important in connection with optical fibers because of their H2 sensitivity. Such plasticizers are also not harmful to health, difficult to ignite and not very volatile. If plasticizers are used, the mass absorption of polyolefin ferrules is ⁇ 1% by weight.
- plasticizers have a relatively high molecular uniformity of their compounds. So-called monomer plasticizers in particular are absolutely molecularly uniform. However, polymer plasticizers also show a relatively high molecular uniformity of their compounds. The fixing of the properties, such as the temperature behavior, the flash point, the vapor pressure, the viscosity and the dripping behavior, can thus be set and stabilized particularly well. Specifically on that Dripping behavior has a particularly positive effect when using relatively uniformly structured molecules.
- plasticizers are preferably used which are still liquid at 20 ° C, or a viscosity of below
- the processing that takes place at room temperature e.g. introduction of the filling compound into a protective sheath or into a cable jacket
- introduction of the filling compound into a protective sheath or into a cable jacket can thus be carried out in a particularly simple and quick manner.
- the proportion of plasticizers should be between 30% and 99% by weight, preferably between 80% and 95% by weight of the filling compound.
- the filling compound thus receives its formative behavior through the proportion of the plasticizer within the overall composition.
