Definitions

  • the invention relates to a silane-crosslinkable polymer mixture for sheathing electrical and / or optical cables and lines, containing copolymers of ethylene vinyl acetate and ethylene butyl acrylate, organic SiLan grafted thereon for crosslinking, a crosslinking catalyst and a flame-retardant filler.
  • Polymer mixtures of the type mentioned for sheathing cables and lines are available in the trade. After admixing the KataLysator, they are mainly processed by extrusion, whereby the action of moisture from the surrounding atmosphere as a result of the grafted-on SiLane leads to silane crosslinking or vulcanization.
  • DibutyL tin dilaurate in the form of a 10% batch based on EVA is used as the catalyst.
  • SiLan crosslinking can be accelerated by introducing the extruded product into hot water or treating it with steam.
  • the crosslinked product has an elongation at break of about 130% and an oxygen index of 29%.
  • the material is not flame retardant enough, which is shown by the relatively low oxygen index. An increase in flame retardancy the addition of additional aluminum hydroxide is not possible with this material. In addition, the material has too low flexibility for some applications.
  • the object of the present invention is to modify the polymer mixture mentioned at the outset in such a way that the crosslinked product has a substantially better flame resistance and greater flexibility.
  • the combination of the polymer mixture mentioned at the beginning with an ethylene-vinyl acetate copolymer with a vinyl acetate content of 50X ensures that the mixture can absorb a considerable amount of aluminum hydroxide, which greatly improves the flame resistance of the end product.
  • the end product has much greater flexibility than the polymer mixture mentioned at the beginning.
  • the mixture can be crosslinked like the usual silane-crosslinkable polymer mixtures.
  • the end product has an elongation at break of 150% and thus meets the requirements of VDE 0207 Part 27 better than the starting mixture.
  • the oxygen index is approx. 40%, which shows that the flame retardancy could be significantly improved.
  • the fire test according to VDE 0472 part 804C is therefore also carried out with thin cables held.
  • the modified material is considerably more flexible than the silane-crosslinked material mentioned at the beginning.
  • the crosslinkable polymer mixture according to the invention has the composition given below, the ethylene vinyl acetate being referred to as EVA and the vinyl acetate as VA:
  • the preferred composition consists of the following parts:
  • the cross-linked insulating compound has the following properties:
  • the crosslinking time of 1mm thick die cuts is approx. 3 hours in a 70 ° C water bath with the usual addition of 3% catalyst as a batch.
