Definitions

  • the present invention relates to an electrical insulating micaceous and fire-retardant adhesive tape, in particular for an electrical or optical fiber cable, comprising at least one sheet of mica paper and at least one reinforcement sheet agglomerated to the sheet of mica paper by a binder, the sheet of mica paper being provided on its face opposite to the reinforcement sheet with a layer of adhesive.
  • the object of the present invention is to provide an adhesive tape on the side of the mica paper, the adhesive power of which is preserved for a very long period, which can be bonded at any time on very diverse substrates, and which are moreover sensitive. to pressure, so that a simple contact without pressure does not cause sticking, but which ensures a strong bonding as soon as there is pressure between the tape and the surface on which it is to be bonded.
  • the micaceous insulating tape according to the invention is characterized in that its adhesive consists of a curable silicone resin added with a curing catalyst.
  • the silicone resin is a polysiloxane resin, preferably a methyl-polysiloxane resin.
  • the reinforcement sheet is a glass fabric of grammage between 15 and 90g / m2.
  • the reinforcement sheet is a chain comprising 5 to 12 strands per cm2 and of title EC5-5.5 to EC9-68.
  • the reinforcement sheet consists of a film, a fabric or a felt made of synthetic polymer.
  • the synthetic polymer is a polyester, a polyimide, a polyamide or a polycarbonate or polytetrafluoroethylene.
  • the reinforcement sheet is agglomerated with the micaceous paper sheet using a polysiloxane resin added with a curing catalyst.
  • the sheet of mica paper is made of muscovite or phlogopite mica, preferably of grammage 45g / m2 to 200g / m2.
  • the sheet of mica paper is covered on both sides with a reinforcing sheet, only one of these two sheets being provided with an adhesive resin.
  • the adhesive is a glass fabric with a grammage between 15 and 90g / m2, a chain comprising 5 to 12 strands per cm2 of glass strands of title EC5-5.5 to EC9-68, or a film, a fabric or a synthetic polymer felt coated on one side with an adhesive resin, and on the other side with a binder with the sheet of micaceous paper.
  • a chain title such as E.C. 5.5-5.5 signifies a chain formed from glass strands E, obtained by spinning mode C, into 5.5 tex threads with a diameter of 5 microns.
  • a sheet of phlogopite mica paper at 120 g / m2 is laminated with a binder of methyl-polysiloxane synthetic resin added with 2% by weight of cobalt naphthenate, as hardening catalyst, on a glass fabric of grammage 33 g / m2, the paper mica being coated with the same synthetic resin, but devoid of curing additive.
  • the glass fabric can be replaced by a chain formed from 5 to 12 strands per cm, made of glass thread of 5.5 to 68 tex, of diameter 5 to 9 microns, arranged parallel in the direction of the unwinding of the ribbon on a synthetic polymer film, especially polyester.
  • a sheet of phlogopite mica paper at 80 g / m2 is laminated with a binder of methyl polysiloxane resin, added with 2% by weight of cobalt naphthenate hardener, on a polyester film, in particular of polyethylene terephthalate glycol, 12 microns thick, the mica paper being coated with the same synthetic resin without hardener additive.
  • a 75g / m2 sheet of muscovite mica paper is laminated with a binder of methyl-polysiloxane resin, added with 2% by weight of cobalt naphthenate, between two polyester films 12 microns thick, one of these two films, intended to be placed on the side of the sheath of the cable to be protected, being coated with the same methyl-polysiloxane resin without hardening additive.
  • the adhesive may be, instead of a silicone resin, a glass fabric, a chain of strands of glass threads or a film, fabric or felt of synthetic polymer, of the same kind as the reinforcing sheet mentioned above, and provided on both sides with an adhesive resin, with the addition of a catalyst on the side of the micaceous paper sheet.
  • the electrical insulating and fire-retardant adhesive micaceous tape is particularly suitable for the insulation of electrical or fiber optic conductors, it is also applicable to the insulation of other surfaces which it is desired to protect against fire in electrical engineering. , especially in transformers.
