Description
Technical field
The utility model relates to wire and cable field more particularly to a kind of cables for ship.
Background technique
Cable in the development of the national economy as handling cable and propagate information carrier, play the role of it is huge, by
To the influence of China's ocean development strategy implementation, domestic shipping industry faces great development space.China can successfully manufacture new
Type ship type is continuously increased, and will further pull on the market demand of cable for ship.It is influenced, is handed over by ship computer room working environment
The use environment for flowing power cable is complicated, and burning is easy when encountering high temperature, for certain there are combustible liquid fuel and high temperature
Extreme environment occasion needs the power cable of a kind of flame retardant property and excellent fire retarding performance to guarantee the power supply of critical facility
And the safety of operation occasion, the normal operation of certain time is able to maintain in flame combustion.But it is existing
Warship ship power cable, fire-retardant and fire resistance is less desirable, there are security risk, needs to improve.
Summary of the invention
Technical problem to be solved in the utility model is in view of the above shortcomings of the prior art, to provide a kind of efficiently resistance
Combustion, the flame-retardant fire-resistant power cable peculiar to vessel of fire resisting.
In order to solve the above technical problems, the technical solution that the utility model is taken are as follows: flame-retardant fire-resistant power cable peculiar to vessel, packet
Include multiple cable cores and be successively wrapped in from inside to outside the filled layer of cable core periphery, inner sheath, flame retardant coating, fireprotection layer, armor and
Oversheath, the cable core are twisted by multiple insulated wire cores, and the insulated wire cores are extruded absolutely by strands tinned copper conductor
Edge layer is constituted, and the flame retardant coating is formed by the double-deck Mica tape, and the fireprotection layer is ammonium phosphate salt particle.
Preferably, the granularity of the ammonium phosphate salt particle of the fireprotection layer is 10~100 microns.
The beneficial effects of adopting the technical scheme are that under fire or hot environment, oversheath and armouring
After damage layer failure, a series of decomposition reactions occur under the high temperature action of flame for the ammonium phosphate salt particle of fireprotection layer, on the one hand,
The ammonia and vapor of generation play the role of cooling and the effect of dilution oxygen concentration, decomposition product phosphorus pentoxide can be formed
Glassy coating separates cable with the oxygen in air, and on the other hand, the free ammonia for decomposing generation can be reacted with flame combustion
The OH radical reaction of middle generation reduces and terminates the free radical of combustion reaction generation, reduces combustion rate, work as flame
Middle the concentration of free ammonia is sufficiently high, sufficiently large with flame contact area, and free radical stops rate and is greater than the rate that combustion reaction generates,
Looping combustion reaction is terminated, and leads to fray-out of flame；The mica tape of flame retardant coating has excellent high temperature resistance and flame resistance
Can, there is good flexibility under normal conditions, meeting the volatilization that harmful vapors are substantially not present when open fire burning, tied using bilayer
Structure plays heat insulation；The granularity of ammonium phosphate salt particle is 10~100 microns, and the ratio of total surface area and volume is big, activity
Height, fast by thermal decomposition rate, capture free radical ability is strong, and fire protection flame retarding efficiency is higher.
Detailed description of the invention
Fig. 1 is the utility model flame-retardant fire-resistant power cable structural schematic diagram peculiar to vessel.
In figure, 1: tinned copper conductor；2: insulating layer；3: filled layer；4: inner sheath；5: flame retardant coating；6: fireprotection layer；7: armouring
Layer；8: oversheath.
Specific embodiment
The utility model is further elaborated combined with specific embodiments below.
As shown in Figure 1, the utility model flame-retardant fire-resistant power cable peculiar to vessel, including multiple cable cores and successively wrap from inside to outside
It is rolled in filled layer 3, inner sheath 4, flame retardant coating 5, fireprotection layer 6, armor 7 and the oversheath 8 of cable core periphery, the cable core is by multiple
Insulated wire cores are twisted, and the insulated wire cores are made of 1 extruded insulation layer 2 of strands tinned copper conductor, the flame retardant coating 5
It is formed by the double-deck Mica tape, the fireprotection layer 6 is ammonium phosphate salt particle.The ammonium phosphate salt particle of fireprotection layer 6 is in flame
A series of decomposition reactions occur under high temperature action, on the one hand, the ammonia and vapor of generation play the role of the oxygen that cools and dilute
The effect of gas concentration, decomposition product phosphorus pentoxide, which can form glassy coating, separates cable with the oxygen in air, another
Aspect, decompose generation free ammonia can be reacted with flame combustion in the OH radical reaction that generates, reduce and terminate combustion reaction
The free radical of generation, reduces combustion rate, enough with flame contact area when the concentration of free ammonia is sufficiently high in flame
Greatly, free radical stops the rate that rate is greater than combustion reaction generation, and looping combustion reaction is terminated, and leads to fray-out of flame；Fire resisting
The mica tape of layer 5 has excellent high temperature resistance and flame resistance energy, has good flexibility under normal conditions, is meeting open fire combustion
The volatilization of harmful vapors is substantially not present when burning, using double-layer structure, plays heat insulation, prevents core temperature excessively high so that absolutely
2 premature failure of edge layer.
As further improvement of the utility model embodiment, the granularity of the ammonium phosphate salt particle of the fireprotection layer 6 is
10~100 microns, the ratio of total surface area and volume is big, and activity is high, fast by thermal decomposition rate, and capture free radical ability is strong,
Fire protection flame retarding efficiency is higher.
