Abstract

The utility model discloses a fireproof insulated glass fiber cased pipe. The fireproof insulated glass fiber cased pipe comprises an insulating layer and a braiding layer the cross sections of which are annular, the braiding layer is wrapped on the external surface of the insulating layer, the braiding layer is of a net structure weaved by alkali-free glass fiber filaments, and the alkali-free glass fiber filaments are soaked with a silicone resin at a high temperature. Compared to conventional glass fiber pipes, the fireproof insulated glass fiber cased pipe is better in high temperature resistance and insulation effect.

Description

The hot-face insulation glass fibre sleeve

Technical field

The utility model relates to the cable sleeve technology, is specifically related to a kind of glass fibre sleeve.

Background technology

At present, application is for automobile, shipbuilding; electrothermal device, electron beam lines, lamp decoration; motor device field glass fibre sleeve, due to its residing operational environment, therefore require it to have good heat-resisting quantity; resistance to wear, dielectricity, self-extinguishment; and the fire resistance of current existing glass fibre sleeve, insulating properties and anti-thermal effect are all undesirable; particularly under high strength hot-fluid radiation event, not good enough to the thermal protection effect of protected object, still can not meet the client and use needs.

The utility model content

For the deficiencies in the prior art, the purpose of this utility model aims to provide a kind of high temperature resistant, hot-face insulation glass fibre sleeve that insulation effect is more desirable.

For achieving the above object, a kind of hot-face insulation glass fibre sleeve of the utility model, comprise that cross section is insulating barrier and the braid of ring-type, described braid is wrapped in described insulating barrier outer surface, described braid is the network structure formed by the braiding of alkali-free glass fibre silk, and described alkali-free glass fibre silk high temperature is soaked with silicones.

Preferably, described insulating barrier is polytetrafluoroethylene, fluorinated ethylene propylene copolymer on the basis of such scheme.

The utility model compared with prior art, because having adopted 1. braids to adopt, it by the glass fiber that is soaked with silicones, is worked out, therefore, silicones can be full and uniform be attached on glass fiber, thereby not only can effectively guarantee the braid heat-resisting ability, simultaneously, can reduce the thickness of braid; At braid peripheral hardware one by the insulating barrier that the particle of polytetrafluoroethylene, fluorinated ethylene propylene copolymer is squeezed into, it is compared with adopting layer of polyurethane, its price is cheaper, and has better insulation, acidproof, oil resistant, heatproof, decay resistance.

The accompanying drawing explanation

Fig. 1 is a kind of hot-face insulation glass fibre sleeve of the utility model schematic cross-section.

Embodiment

Below, by reference to the accompanying drawings and embodiment, the utility model is described further:

Refer to Fig. 1, the utility model provides a kind of hot-face insulation glass fibre sleeve, comprises that cross section is the insulating barrier 10 of ring-type and the braid 20 of ring-type, and described braid 20 is wrapped in described insulating barrier 10 outer surfaces, wherein:

Described braid 20 is the network structures that formed by the braiding of alkali-free glass fibre silk, and this alkali-free glass fibre silk high temperature is soaked with silicones, because silicones is immersed on alkali-free glass fibre by high temperature, therefore, for the fibre pipe that is sprayed at the alkali-free fiber layer surface, to be attached to the alkali-free filament more even because of it, the face that does not exist the alkali-free filament not adhere to, thus can greatly improve its heat-resisting ability.

On the basis of said structure, insulating barrier 10 of the present utility model is polytetrafluoroethylene, fluorinated ethylene propylene copolymer, make insulating barrier 10 shells have good anti-flammability and antiacid alkali resistance, in the useful life that can greatly improve electric wire, electric wire can be used in well-to-do scope.

For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and the distortion all should belong to the protection range of the utility model claim within.
