Problems solved by technology
[0002] Communication cables are now widely used. Cables are widely laid in the wild, underground, and at the bottom of the ocean. The environment is harsh. At the same time, communication cables have high requirements for communication quality. After long-term use of existing communication cables, the outer layer peels off and the shielding layer If it is broken, the cable signal is affected. At the same time, in the event of a fire, the cable jacket is easily broken, releasing toxic gas, and affecting the interruption of the signal communication of the cable.

Embodiment Construction
[0018] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0019] see figure 1 , the embodiment of the present invention includes:
[0020] The fluoroplastic communication cable includes a four-layer structure, which is a nitrile rubber layer, a flame-retardant layer, a filling layer and a shielding layer in sequence from outside to inside.
[0021] The nitrile rubber layer is located at the outermost layer of the fluoroplastic communication cable, which plays a supporting role for the communication cable. At the same time, the insulating phosphor layer is coated on the nitrile rubber layer, which is convenient for the cable to operate in dark light. laid in state.
[0022] The flame retardant layer is...

Abstract
The invention discloses a fluoroplastic communication cable. The fluoroplastic communication cable comprises four structure layers and sequentially comprises a butyronitrile rubber layer, a flame retardation layer, a filling layer and a shielding layer, wherein the filling layer employs fiberglass and silica gel filler, the filling layer is internally provided with six copper conductors and three hard packing bag layers, shielding isolation boards are respectively arranged among the six copper conductors and are used for realizing shielding among the copper conductors to prevent signal interference, and the seventh copper conductor is externally wrapped in the shielding layer. The fluoroplastic communication cable has advantages of high and low temperature resistance, anti-oxidation performance, long service life and high safety coefficient.
Description
technical field [0001] The invention relates to the field of fluoroplastic products, in particular to a fluoroplastic communication cable. Background technique [0002] Communication cables are now widely used. Cables are widely laid in the wild, underground, and at the bottom of the ocean. The environment is harsh. At the same time, communication cables have high requirements for communication quality. After long-term use of existing communication cables, the outer layer peels off and the shielding layer If it is broken, the cable signal is affected. At the same time, in the event of a fire, the cable jacket is easy to rupture, releasing toxic gas, and affecting the interruption of the signal communication of the cable. [0003] The existing fluoroplastics are developing rapidly. Fluoroplastics are part or all of hydrogen replaced by fluorine. There are polytetrafluoroethylene, polyperfluoroethylene, polytrifluoroethylene, and polyvinylidene fluoride. Fluoroplastics are use...
