The technical scheme adopted by the utility model to solve the technical problem is as follows:
Tension fire-proof insulation casing is compiled including the first insulating layer and the first glass fibre being arranged in outside the first insulating layer Tissue layer, the first insulating layer inner wall are provided with internal flexible glue layer, are embedded with the tension being axially arranged in the internal flexible glue layer Metallic cable, internal flexible glue layer inner wall are coated with interior fire protection coating, are provided with second outside the first fiberglass braided layer Insulating layer, is provided with the second fiberglass braided layer outside the second insulating layer, outside the second fiberglass braided layer It is provided with layer of silica gel, copper-wire braided layer is provided with outside the layer of silica gel, is provided with polyvinyl chloride outside the copper-wire braided layer Layer, it is provided with abrasive rubber layer outside the polyvinyl chloride layer, external adhesive layer is provided with outside the abrasive rubber layer, it is described Outside attachment layer surface is coated with external fire resistant coating, and the layer of silica gel is bonded in the second glass fibre by epoxy resin layer and compiles Tissue layer outer surface.
As an improvement of the above technical solution, the copper-wire braided layer is formed by proof copper-wire braided, the plating of proof copper-wire braided layer surface There is zinc protective layer.
As a further improvement of the above technical scheme, first insulating layer and second insulating layer are electro-insulating rubber Layer, the electro-insulating rubber layer are ethylene-propylene-diene monomer glue-line.
As a further improvement of the above technical scheme, double-layer structure adjacent in casing becomes one by adhesive bonding A entirety.
As a further improvement of the above technical scheme, the described first fiberglass braided layer and second fiberglass braided Layer is woven by alkali-free glass fibre.
As a further improvement of the above technical scheme, the alkali-free glass fibre is soaked with organic siliconresin.
As a further improvement of the above technical scheme, the layer of silica gel is organosilicon glue-line.
The beneficial effects of the utility model are: the utility model provides a kind of tension fire-proof insulation casing, this kind of tension Axially be embedded with tension metallic cable in the inside flexible glue layer of fire-proof insulation casing, can significant increase casing tensile strength, favorably Cable inside protection sleeve pipe;In addition, first insulating layer and second insulating layer can provide enough insulation for casing Performance, situations such as avoiding the occurrence of electric leakage;Further more, the interior fire protection coating and external fire resistant coating can be inside and outside casings Casing is protected, the high-temperature stability of casing is more preferable, and fire resistance property is higher, is conducive to the safety for promoting casing.
In short, this kind of tension fire-proof insulation casing solves, tensile capacity existing for existing casing is poor, fire protecting performance is poor, absolutely Edge performance is insufficient, service life is short, there are the technological deficiencies such as security risk.
