Description
Technical field
The utility model relates to technical field of electric wires and cables, and in particular to it is a kind of based on can Ceramic composite material it is fire-retardant
Cable.
Background technique
With the quickening of social development and urbanization process, density of population sharp increase, public place and public transport
The security against fire of facility is increasingly prominent.How unimpeded, the reduction cable in a fire electric power and communication line important circuit is ensured
A large amount of poisonous and harmful dense smoke when burning, and make power cable not and become the hazardous material of transmitting flare, this is modern architecture work
In journey the problem of urgent need to resolve.
Summary of the invention
The technical issues of the utility model is solved is to provide a kind of nontoxic, fire-retardant, environmentally friendly, resistant to high temperature and adapts to weight
Want the flame retardant cable of engineering demand.
The technical solution adopted in the utility model is: a kind of flame retardant cable based on Ceramic composite material, including conduction
Core, refractory insulating layer, filled layer, belting layer and restrictive coating.The outside of conductor wire core coats refractory insulating layer, refractory insulating layer
Outside be coated with filled layer, belting layer is coated on the outside of filled layer, is coated with restrictive coating on the outside of belting layer.Hot-face insulation
Layer and restrictive coating use can Ceramic silicon rubber composite material.
The conductor wire core is single copper free wire, is also possible to multiply copper free wire and is twisted.
The belting layer, which is that the overlapping of hydroxyapatite incombustible paper is wrapped, to be formed.
The refractory insulating layer and restrictive coating are squeezed out using plsitive mold.
The utility model provide it is a kind of based on can Ceramic composite material flame retardant cable.The utility model can ceramic SiClx
Rubber composite material be silicon rubber-polysilsesquioxane block polymer, have at normal temperature usual silicone rubber it is non-toxic and tasteless,
High-low temperature resistant, good electrical insulation performance and good processing performance.After encountering high temperature or flame ablation, it can be formed hard
Ceramic protective layer plays the role of fire-retardant, fire resisting, the original shape and structure of composite material can be preferably kept, to protect
The mechanically and electrically performance of inside cable does not change.
As refractory insulating layer and restrictive coating can Ceramic composite material be to be squeezed out using plsitive mold, have high
Elongation at break (> 200%), and it is easy to process.
As refractory insulating layer and restrictive coating can Ceramic composite material start to be hardened in 450 DEG C of temperatures above, highest
Refractory temperature is up to 1000 DEG C；At least tolerance burning time is 90 minutes.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model；
In figure: conductor wire core (1), refractory insulating layer (2), filled layer (3), belting layer (4) and restrictive coating (5).
Specific embodiment
As shown in Figure 1, a kind of flame retardant cable based on Ceramic composite material, including conductor wire core (1), refractory insulating layer
(2), filled layer (3), belting layer (4) and restrictive coating (5).Conductor wire core (1) can be single copper free wire, be also possible to multiply
Copper free wire is twisted.Refractory insulating layer (2) can Ceramic silicon rubber composite layer for tight conductor wire core；This
Utility model can Ceramic silicon rubber composite material be silicon rubber-polysilsesquioxane block polymer, have at normal temperature general
Logical the non-toxic and tasteless of silicon rubber, high-low temperature resistant, good electrical insulation performance and good processing performance.Encountering high temperature or flame
After ablation, hard ceramic protective layer can be formed, plays the role of fire-retardant, fire resisting, can preferably keep composite material original
Shape and structure, so that the mechanically and electrically performance of inside cable be protected not change.
Filled layer (3) be alkali-free glass fibre, alkali metal oxide content less than 0.8%, play electrical isolation, fire insulation and
Skeleton humidification.
Belting layer (4) is hydroxyapatite incombustible paper；Using wrapped technology is overlapped, Duplication is not less than 15%, plays
Fire retardation.
Restrictive coating (5) is can Ceramic silicon rubber composite layer, material and effect and the refractory insulating layer (2) phase
Together.
The utility model is equipped with multi-layer fireproofing flame retarding construction, ensure that the synthesis fire protecting performance of utility model.
The utility model is not limited to above-mentioned preferred forms, anyone can obtain under the enlightenment of the utility model
Other various forms of products, however, make any variation in its shape or structure, it is all that there is same as the present application or phase
Approximate technical solution, all falls within the protection scope of the utility model.
