Abstract
The utility model discloses a kind of novel flame-retardant fireproof environmental cables comprising conductor, insulation, filling, band, sheath, six part of fire-retardant fireproof layer composition.Insulation can be single layer low-voltage cable structure, be also possible to three-layer co-extruded medium and high voltage cable structure.After cable installation, by sprinkling water to cable-flame retardant fireprotection layer, water penetrates into silicate filled layer by braided fabric gap, and solidification is sufficiently merged with silicate, one layer of curing concrete structure is formed, plays the effect of fire-retardant fireproof.
Description
Technical field
The utility model relates to a kind of novel flame-retardant fireproof environmental cable, it is mainly used for protecting fire-retardant, fire prevention and environment
Shield has the occasion of particular/special requirement to use.
Background technique
As people are higher and higher to the densely populated place fire-fighting such as market, subway, building and the requirement of environment, to offer
The cable of electric power has been required to fire-retardant, fire prevention, environmental requirement.The fire-retardant of industry announcement at present, fire prevention, environment-friendly cable predominantly exist
Increase the fire prevention insulating layer that magnetization silicon rubber or other similar material are made into cable to realize, production method is extrusion type.
In order to which this layer of structure is realized extrusion mode, it is necessary to which this layer of structural material has certain mobility, necessarily increases
The addition of some organic lipids or olefines material, these materials increases the processing performance of material, but also reduces material
It is fire-retardant, fire prevention, environmental protection characteristic.The utility model is exactly under the background that such a properties of product and production technology contradict
It generates, changes the processing method of fire-retardant fireproof environmental protection layer structure, the fire-retardant fireproof environmental protection characteristic for material of sufficiently delivering is realized
The optimum efficiency of product.
Summary of the invention
It is convenient that the purpose of the utility model is to provide a kind of production operations, and product overall flame, fire prevention, environmental protection characteristic are extremely
The excellent construction of cable.
The technical solution of the utility model is: a kind of novel flame-retardant fireproof environmental cable, including conductor, insulation, filling, packet
Band, sheath, six part of fire-retardant fireproof layer composition.
The insulation can be single layer low-voltage cable structure, be also possible to three-layer co-extruded medium and high voltage cable structure.
The fire-retardant fireproof layer is belt structure, wrapped to can be single overlays directly outside the sheath of cable
It is wrapped, it is wrapped to be also possible to multilayer gap.Wrapped Duplication is wrapped smooth to realize not less than 30%, and close effect.
The fire-retardant fireproof layer band has upper layer and lower layer glass braid band or other materials with flame-proof environmental protection characteristic
The braid over braid and silicate of matter fill composition.The count of braid over braid is between 80% ~ 90%, it is ensured that after cable can be allowed to install
Water energy is penetrated into, and can ensure that intermediate silicate powder can be lockked firmly in centre.In order to preferably be uniformly distributed, upper
Between lower two layers of braided fabric and silicic acid salt filling, is sewed and fixed by cordage.
The fixed sewing of the fiber forms three sewing threads along band longitudinal direction, and the spacing between every two needle of sewing does not surpass
Cross 5mm.Ensure that silicic acid salt filling is uniformly fixed between upper layer and lower layer braided fabric, forms whole strip lap operating process
In, hydrochlorate filler is not fallen.
After cable installation, by sprinkling water to cable-flame retardant fireprotection layer, water penetrates into silicate by braided fabric gap
Filled layer sufficiently merges solidification with silicate, forms one layer of curing concrete structure, plays the effect of fire-retardant fireproof.
Detailed description of the invention
In order to make the content of the utility model be easier to be clearly understood, below according to specific example with reference
The utility model is described in further detail, wherein Fig. 1 is the structural schematic diagram of the utility model；Fig. 2 is 6 resistance in Fig. 1
Fire fireprotection layer belt structure schematic diagram；Label in attached drawing are as follows: conductor 1, insulation 2, filling 3, band 4, sheath 5, fire-retardant fireproof
Layer 6, glass braid 61, silicic acid salt filling 62, fiber sewing 63.
Specific embodiment
See Fig. 1, Fig. 2, a kind of novel flame-retardant fireproof environmental cable of the utility model, including conductor 1, insulation 2, filling 3, packet
Band 4, sheath 5, fire-retardant fireproof layer 6 form.
The insulation 2 can be single layer low-voltage cable structure, be also possible to three-layer co-extruded medium and high voltage cable structure.
The fire-retardant fireproof layer 6 is belt structure, wrapped to can be single layer weight directly around 5 outside of the sheath of cable
It is wrapped to be also possible to multilayer gap for lap wound packet.Wrapped Duplication is wrapped smooth to realize not less than 30%, and close effect.
6 band of fire-retardant fireproof layer has upper layer and lower layer glass braid band 61 or other with flame-proof environmental protection characteristic
The braid over braid and silicate of material fill composition.The count of braided fabric 61 is between 80% ~ 90%, it is ensured that cable can be allowed to pacify
Water energy is penetrated into after dress, and can ensure that intermediate 62 powder of silicic acid salt filling can be lockked firmly in centre.In order to better
It is uniformly distributed, it is fixed by cordage sewing 63 between upper layer and lower layer braided fabric 61 and silicic acid salt filling 62.
The fixed sewing 63 of the fiber forms three sewing threads along band longitudinal direction, and the spacing between every two needle of sewing is not
More than 5mm.Ensure that silicic acid salt filling 61 is uniformly fixed between upper layer and lower layer braided fabric, forms whole strip lap and operated
Cheng Zhong, hydrochlorate filler 62 are not fallen.
After cable installation, by sprinkling water to cable-flame retardant fireprotection layer, water penetrates into silicic acid by 61 gap of braided fabric
Salt filled layer 62 sufficiently merges solidification with silicate, forms one layer of curing concrete structure, plays the effect of fire-retardant fireproof.
