Abstract
The utility model discloses two flexible fire-resistant cables, wherein one flexible fire-resistant cable adopts the structure that a polytetrafluoroethylene belt layer is wrapped outside a conductor, a glass fiber yarn layer is woven outside the polytetrafluoroethylene belt layer, a glass fiber belt or flame-retardant glass fiber cloth layer is wrapped outside the glass fiber yarn layer, and the outermost layer adopts a sheathing layer; and the glass fiber belt or flame-retardant glass fiber cloth layer and the glass fiber yarn layer of the other flexible fire-resistant cable are transposed. In the utility model, the glass fiber yarn layer and the glass fiber belt layer or the flame-retardant glass fiber cloth layer can achieve a better flame-retardant effect and also can prevent heat from being transferred to an insulation layer. The polytetrafluoroethylene has higher melting point and is hard to melt, and the woven glass fiber yarn layer also can achieve a better shaping effect, so that the normal functions are maintained, and a better flexibleness of the cables is ensured.
Description
Technical field
The utility model relates to a kind of cable, specifically is two kinds of flexible fire-proof cables.
Background technology
Fireproof cable plays epochmaking effect in the building of modern city, because it is densely populated in the building, except its reach safely fire protection equipment must be complete, in case breaking out of fire, circuit of systems such as its control electric power, supervision, guiding and alarm must can be kept normal function.Otherwise not only life and property will be committed to the flames, also many social concerns can take place.Existing fireproof cable is wrapped mica tape on cable insulation often, and the hardening of mica sintering can continue to play the effect of insulation when cable fire.No matter be synthetic mica tape, phlogopite band or white clouds master tape, its processing method all is mica powder to be copied make mica paper, with adhesive glass cloth is sticked on one or both sides again and makes, after being bonded together, again through stove oven dry, rolling then cuts into the belt of different size again.In mica tape was made, the quality of glass cloth directly influenced the mechanical strength of product, and adhesive then is to guarantee the not stratified key factor of belt.Mica tape is harder, flexible cable particularly core hour can make whole cable hardening, and wrapped at mica tape, in the processes such as cable processing subsequently, transportation, use, mica all very easily peels off, and does not obviously reach instructions for use.
The utility model content
Technical problem to be solved in the utility model provides two kinds of not only good flame retardation effect, and more soft, the flexible fire-proof cable of processing characteristics.
Flexible fire-proof cable described in the utility model comprises conductor, outside described conductor, sets gradually to be wrapped polytetrafluoroethylene belt, and the braided glass fibre layer, wrapped glass fiber tape or fireproof glass silk layer of cloth, outermost layer is a restrictive coating.
Another kind of flexible fire-proof cable described in the utility model comprises conductor, outside described conductor, sets gradually to be wrapped polytetrafluoroethylene belt, and wrapped glass fiber tape or fireproof glass silk layer of cloth, braided glass fibre layer, outermost layer are restrictive coating.
Above-mentioned conductor can be single solid conductor, stranded conductor or bundle strand conductor.
The wrapped belt of described polytetrafluoroethylene is a base material with the polytetrafluoroethylene film of handling through the surface polarization, and the agent of silicon-coating ketone pressure-sensitive adhesive constitutes.
Described glass fibre layer is alkali-free glass fibre yarn or medium-alkali glass fibre yarn, and preferably selecting for use by many diameters is that the medium-alkali glass fibre of 6-8 μ m and twist with the fingers forms.The glass fibre belt then is the alkali-free glass fibre band.
Described fireproof glass silk cloth forms the LSOH anti-flaming glass wool cloth of preferably selecting for use inorganic combustion inhibitor to make for the glass wool cloth single or double applies anti-flaming dope.
Flexible fire-proof cable of the present utility model, when breaking out of fire, braided glass fibre layer and wrapped glass fibre belt or fireproof glass silk layer of cloth can play flame retardant effect preferably, and can isolate heat as the insulating barrier transmission.In addition, polytetrafluoroethylene all has higher fusing point than polyvinyl chloride, polyethylene and crosslinked polyethylene etc., when catching fire, can not melt, and the glass fibre layer of braiding also can play styling preferably, thereby can keep normal function in the inside for a long time.Adopt the wrapped form of polytetrafluoroethylene can avoid polytetrafluoroethylene hardness big, extrude the shortcoming of back core hardening, conductor adopts bundle strand conductor, thereby cable can keep flexibility preferably.
Description of drawings
The structural representation of Fig. 1 the utility model single-core cable.
The structural representation of Fig. 2 the utility model multicore cable.
Embodiment
As shown in Figure 1, flexible fire-proof cable described in the utility model has two kinds of analog structures, wherein a kind of structure of flexible fire-proof cable is: at first wrapped polytetrafluoroethylene belt 2 outside conductor 1, the braided glass fibre layer 3 again, wrapped then glass fiber tape or fireproof glass silk layer of cloth 4 extrude restrictive coating 5 at last again.
The structure of another kind of flexible fire-proof cable is: at first wrapped polytetrafluoroethylene belt 2 outside conductor 1, and wrapped glass fiber tape or fireproof glass silk layer of cloth 4, the braided glass fibre layer 3 again, extrude restrictive coating 5 at last again.
Described conductor 1 can when the cross section is big, better be selected bundle strand conductor for use for single solid conductor or stranded conductor or bundle strand conductor according to cross-sectional sizes.
Cable can when there is the sheath material outside, better adopt fire-retardant sheath material or low-smoke non-halogen flame-retardant sheath material for single core (Fig. 1) or multicore (Fig. 2), and multicore cable is filled a kind of glass cord of better selecting for use.
