Abstract
The invention discloses a ceramic fireproof and fire-resistant silicone rubber cable. The ceramic fireproof and fire-resistant silicone rubber cable includes a ceramic fireproof and fire-resistant silicone rubber insulating cable core, a filler, a ceramic fireproof and fire-resistant composite tape and a ceramic fireproof and fire-resistant silicone rubber sheath which are arranged sequentially from inside to outside; the insulating cable core includes wires and insulating layers which are wound on the outer layers of the wires; and the filler is a ceramic fireproof and fire-resistant silicone rubber filler. According to the ceramic fireproof and fire-resistant silicone rubber cable of the invention, the ceramic fireproof and fire-resistant silicone rubber insulating layers is adopted as a multi-layer structure, and therefore, the ceramic fireproof and fire-resistant silicone rubber cable has the advantages of multi-layer safe guarantee and excellent fireproof effects.
Description
Technical field
The present invention relates to field of cables, be specifically related to a kind of ceramic fireproof silicone rubber for cable.
Background technology
Common fire-retardant, low cigarette macromolecular material, as after the burning of plastics, rubber and silicon rubber, residue is ashes, cable causes line short after being burnt very soon.At present, what adopt both at home and abroad is the fire-resisting cable that mica tape asbestos are wound around mostly.The fire-resisting cable that mica tape and asbestos are wound around, need multi-lay winding in process of production, due to the restriction of process conditions, overlapping the slot place is often easily caused to occur defect, mica tape embrittlement after burning, easily come off, also cause fire-resistant weak effect, thus be difficult to ensure communication, electric power in case of fire safe and smooth.
Summary of the invention
A kind of fire prevention, fire-resistant, fire-retardant, nontoxic ceramic fireproof silicone rubber for cable is the invention provides for solving the problem.
Technical scheme of the present invention:
A kind of ceramic fireproof silicone rubber for cable, comprises the ceramic fireproof silicon rubber insulation cable core, filler, ceramic fireproof composite band and the ceramic fireproof silicone rubber jacket that set gradually from inside to outside; Described insulated core comprises wire and is wound in the insulating barrier of wire external layer; Described filler is ceramic fireproof silicon rubber filling thing.
Described insulated core is 3-12 root; The internal diameter of described wire is 0.5-10mm; Described insulating barrier is for being ceramic fireproof silicone rubber insulation layer.
Beneficial effect of the present invention:
Cable choosing low smoke and zero halogen of the present invention, without phosphorus nitrogen, heavy metal free, nontoxic, harmless not melting, do not drip, do not prolong the ceramic fireproof silastic material of combustion, there is extraordinary fire resistance, flue gas toxity safe class reaches the highest level of security ZA level of macromolecular material, secondary injury is not caused to human body, meets European Union ROHS standard; Sandwich construction of the present invention adopts ceramic fireproof silicone rubber insulation layer, multi-level safety guarantee, and flameproof effect is good; Cable of the present invention, at the temperature of 650 DEG C-3000 DEG C, burns into rapidly the complete housing that ceramic-like is hard, and its housing armouring plays a very good protection to circuit, ensures unobstructed under fire conditions of circuit; Cable of the present invention is soft, good springiness, and intensity is high, good mechanical performance, high temperature resistant, anti-aging, excellent electrical property, normal serviceability temperature-70 DEG C-200 DEG C; Cable fire grade of the present invention reaches the A grade standard of GB/T12666, and performance is tested by the CWZ level Water spray of Britain BS6387, vibrations, refractory chamber.
