Abstract
The utility model discloses a high temperature resistance silicone rubber glass bushing which comprises a glass fiber yarn layer whose cross section presents to be an annular shape, and a silicone rubber layer which is arranged on the internal surface of the glass fiber yarn layer. The external surface of the glass fiber yarn layer is wound with an aluminum membrane winding tape. According to the high temperature resistance silicone rubber glass bushing, flame combustion can be resisted and heat flow radiation can also be resisted so that hear resistance of the glass fiber bushing can be effectively enhanced and thus high temperature resistance capability is increased.
Description
Technical field
The utility model relates to the cable sleeve technology, is specifically related to a kind of high-temperature-resisting silicon rubber glass bushing.
Background technology
To preserving the ecological environment and the pay attention to day by day of self health, the security performance of cable is proposed to higher more fully requirement along with the mankind.Fire-resisting cable is widely used in skyscraper, hotel, large supermarket, hospital, ,Deng public place, station, so that in the situation that fire, can guarantee the unimpeded of electric power and communication within a certain period of time, win to greatest extent the rescue time of precious silicon, reduce the loss.
At present; fire-resisting cable both domestic and external; mainly that skin at cable arranges a protective casing; and existing protective casing structure is mainly to using the alkali-free glass fibre sleeve pipe as the liner sleeve pipe; then apply the high temperature resistant heat insulation coating at the neck bush tube-surface; weave again one deck aramid fiber yarn braided sleeving on the high temperature resistant heat insulation coating after baking; although this high temperature resistant heat insulation sleeve pipe has improved the heat-resisting ability of cable to a certain extent; but; at some, under special occasion, the heat-resisting quantity of the fiberglass pipe of this traditional structure still can not be satisfied the demand.
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-resisting silicon rubber glass bushing.
For achieving the above object, a kind of high-temperature-resisting silicon rubber glass bushing of the utility model, comprise glass fibre layer in the form of a ring of cross section, be located at the silastic-layer of described glass fibre layer inner surface, at described glass fibre layer outer surface, be wound with an aluminium film take-up strap.
On the basis of such scheme, preferably, described glass fibre layer outer surface scribbles silicone layer.
On the basis of such scheme, preferably, described glass fibre layer is formed by the alkali-free glass fibre yarn braiding.
On the basis of such scheme, preferably, described aluminium film take-up strap comprises alkali-free glass fiber cloth, aluminizer and heat-resistant fireproof glue, and described alkali-free glass fiber cloth is bonded together by heat-resistant fireproof glue and described aluminizer.
On the basis of such scheme, preferably, described silicone layer is coated with the high temperature resistant heat insulation layer outward.
On the basis of such scheme, preferably, described high temperature resistant heat insulation layer is 1.2-1.8mm.
Compared with prior art, its beneficial effect is the utility model:
Be wound with aluminium film take-up strap at glass fibre layer outer surface, make this glass fibre sleeve there is good antiradiation performance, when running into the radiation of heat-flash stream, by aluminium film take-up strap, most of hot-fluid is effectively reflected away, glass fibre layer inner surface at this silicon rubber glass bushing is coated with silastic-layer simultaneously, can effectively improve the thermal endurance of glass fibre sleeve by silastic-layer, thereby make glass fibre sleeve there is good heat-resisting ability.
The accompanying drawing explanation
Fig. 1 is the schematic cross-section of a kind of high-temperature-resisting silicon rubber glass bushing of the utility model.
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 high-temperature-resisting silicon rubber glass bushing, is respectively equipped with from the inside to the outside cross section silastic-layer 20, glass fibre layer 10, slim aluminium film take-up strap 30 in the form of a ring, wherein:
Described silastic-layer 20 is coated on the inner surface of glass fibre layer 10;
Described glass fibre layer 10 is closely to be woven and form by alkali-free glass fibre yarn; Outer surface at described glass fibre layer 10 scribbles silicone layer 40, to improve its temperature capacity;
Described slim aluminium film take-up strap 30 is wrapped in the outer surface of silicone layer 40, and it comprises alkali-free glass fiber cloth, aluminizer and heat-resistant fireproof glue, and described alkali-free glass fiber cloth holds tightly together by heat-resistant fireproof glue and described aluminizer.
Under the heat resistance prerequisite that guarantees the high-temperature-resisting silicon rubber glass bushing, in order effectively to control the size of high-temperature-resisting silicon rubber glass bushing, the outer high temperature resistant heat insulation layer (not shown) that be coated with of described silicone layer 40; Described high temperature resistant heat insulation layer is 1.2-1.8mm.
When breaking out of fire or high-temperature work environment, at first the high-temperature-resisting silicon rubber glass bushing effectively reflects away most of hot-fluid by the aluminizer of aluminium film take-up strap 30, when remaining small part heat continues to internal delivery, because inner surface and the outer surface of glass fibre layer 10 is respectively equipped with silastic-layer 20, silicone layer 40, and silicone layer 40 outer surfaces also are coated with the high temperature resistant heat insulation layer, therefore, remaining small part heat also can effectively be intercepted, when ambient temperature continues to raise, the silastic-layer 20 that is positioned at glass fibre layer 10 inner surfaces still can be used as the last protective barrier of protection cable conductive core, thereby in fire or hot operation situation, for the normal operation of cable is raced against time.The triple technology of glass layer that the utility model scribbles silastic-layer 20 by high temperature resistant heat insulation layer, aluminium film take-up strap 30 and inwall combine, the thermal endurance of the silicon rubber glass bushing that can effectively improve, thereby make it under hot environment, can effectively improve the useful life of cable.
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.
