Description

A kind of ceramic polyolefin fire resistant flame retardant cable
Technical field
The utility model is related to electric wire fields, and in particular to a kind of ceramic polyolefin fire resistant flame retardant cable.
Background technology
Currently, common fire-resisting cable is overlapped wrapped phlogopite fire resistant belt or synthetic mica fire resistant belt outside using conductor, then squeeze Make the structure of insulation.Slow due to being overlapped wrapped fire resistant belt speed of production, efficiency is low, increases manufacturing cost.Therefore fire resisting is improved The production efficiency of cable causes concern.
Utility model content
The purpose of this utility model is to provide one kind having good fire resisting, high temperature resistant, fire-retardant, environmentally friendly and superior mechanical The ceramic polyolefin fire resistant flame retardant cable of barrier propterty ensures that cable can circuit be just within the regular hour when fire occurs Often operation, and non smoke and poison gas release, the safe escape of support personnel and being smoothed out for fire-fighting.
The utility model solves the technical solution that above-mentioned technical problem is taken:
A kind of ceramic polyolefin fire resistant flame retardant cable, the cable include flame retardant sheath layer, oxygen barrier successively from outside to inside Layer, fire-resistant wrapping tape and cable core;The cable core is twisted by several insulated single wires, and the gap filling between insulated single wire has resistance Filler is fired, the insulated single wire is disposed with insulating layer, flame retardant coating and conductor from outside to inside;The flame retardant coating is by ceramics Change polyolefin to extrude.
The conductor uses copper wire.
The insulating layer uses polyvinyl chloride or crosslinked polyethylene.
The fire-resistant wrapping tape, which is that the overlapping of high fire-retardance glass tape is wrapped, to be formed.
The oxygen barrier layer is the oxygen barrier filler material of halogen-free and low-smoke flame-retardant polyolefin.
The flame retardant sheath layer is the thermoplastic halogen-free and low-smoke flame-retardant polyolefin material extruded outside oxygen barrier layer.
The beneficial effects of the utility model are embodied in:
Existing fire-resisting cable is wrapped phlogopite fire resistant belt or synthetic mica fire resistant belt to be overlapped outside conductor, then extrude absolutely Edge material, the utility model is related to fire resistant flame retardant cable the resistance to of cable is improved by the adjustment and application to the construction of cable Fiery performance and production efficiency.Flame retardant coating in the utility model is extruded using ceramic polyolefin, meets igneous porcelain, not only resistance to Fiery function admirable, and production efficiency is high.Flame retardant coating, fire-resistant wrapping tape form ceramic material when cable encounters fire, at porcelain, Fire resisting truly is can reach, oxygen barrier layer, fire retardant jacket decomposite hydrate when cable encounters fire, prevent fire Flame is spread, and plays flame retardant effect, ensure cable when fire occurs can within the regular hour circuit normal operation.This practicality is new Raw material employed in type are smokeless, Halogen, non-toxic material, and not will produce smog in high temperature or flame and have Poisonous gas belongs to environment-friendly type fire resistant flame retardant cable.
Further, oxygen barrier layer uses the oxygen barrier filler material of LSOH anti-flaming in the utility model, and oxygen index (OI) is high, meets fire and decomposes Go out to prevent the moisture of propagation of flame, there is good flame retardant effect.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model;
Figure label:1 conductor, 2 flame retardant coatings, 3 insulating layers, 4 flame retardant fillers, 5 fire-resistant wrapping tapes, 6 oxygen barrier layers, 7 fire-retardant shields Jacket layer.
Specific implementation mode
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model ceramic polyolefin fire resistant flame retardant cable, it is characterised in that:The insulated single wire It being made of conductor 1, flame retardant coating 2, insulating layer 3, several insulated single wires are twisted into cable core, and there is flame retardant filler 4 in cable core gap, It is coated with fire-resistant wrapping tape 5 and oxygen barrier layer 6, flame retardant sheath layer 7 successively outside cable core.The characteristics of structure is:
The conductor 1 uses copper wire.
The flame retardant coating 2 is the ceramic polyolefin being extruded in outside conductor.
The insulating layer 3 is the insulating materials being extruded in outside flame retardant coating, including polyvinyl chloride, crosslinked polyethylene etc..
The cable core is twisted by several insulated single wires, and there is flame retardant filler in cable core gap, to ensure cable core structure Rounding.
The fire-resistant wrapping tape 5 is the high fire-retardance glass tape outside cable core.
The oxygen barrier layer 6 is the oxygen barrier filler material of the LSOH anti-flaming extruded outside fire-resistant wrapping tape.
The fire retardant jacket 7 is the thermoplastic halogen-free and low-smoke flame-retardant polyolefin material extruded outside oxygen barrier layer.
The structure and its principle of a kind of ceramic polyolefin fire resistant flame retardant cable of the utility model be:Ceramic polyolefin is resistance to Fiery flame retardant cable includes conductor, flame retardant coating, insulating layer, flame retardant filler, fire-resistant wrapping tape, oxygen barrier layer and flame retardant sheath layer.Wherein Conductor, flame retardant coating and insulating layer form insulated single wire, several insulated single wires form cable core, and there is flame retardant filler in cable core gap, Wrapped fire-resistant wrapping tape, oxygen barrier layer, flame retardant sheath layer successively outside cable core.Flame retardant coating, fire-resistant wrapping tape are when cable encounters fire, at porcelain Ceramic material is formed, can reach fire resisting truly, oxygen barrier layer, fire retardant jacket are decomposited when cable encounters fire Hydrate prevents propagation of flame, plays flame retardant effect.Ensure that cable can circuit be just within the regular hour when fire occurs Often operation.
Above-described specific implementation mode has carried out further the purpose of this utility model, technical solution and advantage Detailed description be not used to limit it should be understood that the foregoing is merely specific embodiment of the present utility model The scope of protection of the utility model, within the spirit and principle of the utility model, any modification made, equivalent replacement, Improve etc., it should be included within the scope of protection of this utility model.
