NOVELTY - Water-proof impact-resistant fire-proof cable comprises a cable core, a self-made water-proof layer, a shielding layer, an inner sheath layer and a self-made fireproof layer. The cable core comprises tinned copper wire core material and a cross-linked polyethylene insulating layer. USE - Water-proof impact-resistant fire-proof cable. ADVANTAGE - The cable has waterproof and impact-resistant fireproof effect, and prevents water molecule from penetrating, at the same time, introducing hydrophobic long chain, the waterproof of the gain cable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of waterproof impact-resistant fireproof cable, comprising: (1) mixing N, N-dimethylformamide and tetrahydrofuran, silane hydroxide compound according to mass ratio of 1: 1: 0.1 to 1: 1: 0.2, stirring and dissolving to obtain spinning solution, electrostatic spinning the cable core to the film layer thickness of 0.1-0.3 mm, then placing under 2kW high pressure mercury lamp, the distance is 200 mm, irradiating for 30-60 seconds to obtain the first waterproof layer cable core; (2) placing the first waterproof layer cable core in the container, sealing, inletting 180°C of zinc nitrate water vapor at 20 ml/hour, reacting for 15-18 hours, taking out, cooling to room temperature, drying at 80°C for 7-10 hours to obtain the self-made waterproof layer cable core; (3) using tinned copper wire to the self-made waterproof layer cable core surface weaving thickness of 0.1-0.3 mm of the shielding layer to obtain the shielding layer cable core; (4) mixing cross-linked polyethylene, polyvinyl chloride resin, linear low density polyethylene, poly 1-butylenes, γ -amino propyl triethoxy silane, silicon dioxide, antioxidant 264, calcium stearate, zinc stearate, epoxy soybean oil according to mass ratio of 1: 2: 1: 1.8: 0.1: 0.2: 0.08: 0.1: 0.05: 1 at 100°C, stirring at 2000 revolutions/minute (rpm) for 1-6 minutes, extruding inner sheath layer to the shielding layer cable core at 145-160°C to obtain inner sheath layer cable core; (5) placing the inner sheath layer cable core under the 2kW high pressure mercury lamp, the distance is 200 mm, spraying the inner sheath layer cable core quality 0.5-0.8 times of diallyl diethoxy silane, irradiating for 44-58 seconds, raising the temperature to 60 °C, spraying the inner sheath layer cable core with mass of 88-100 times of the oxidized graphene solution, where the mass ratio of graphene oxide, deionized water, ascorbic acid is 1: 200: 0.1 to 1: 500: 0.5, reacting for 7-10 hours, placing under the atmosphere of water-alcohol vapour, where mass ratio of deionized water and absolute ethanol in the water-alcohol vapor is 1:9, after allowing to stand for 10-13 hours, freezing at -15°C for 4-7 hours to obtain aerogel cable core; (6) placing the aerogel cable core in the container, spraying aluminum sulfate solution of 0.2-0.4 times of the mass of the aerogel cable core, reacting for 35-48 minutes at 160 °C, spraying the sulfuric acid with mass fraction of 8.9% to 0.01-0.03 times of the mass of the aerogel coated cable core, at 30 kHz ultrasonication for 31-43 minutes, washing using deionized water for 6-8 times, drying for 9-13 hours at 100 °C, spraying malonic acid reaction solution with aerogel of 0.4-0.7 times of the cable core, reacting for 4.5-7 hours, washing for 6 -8 times by using deionized water, drying for 10-14 hours at 60 °C to obtain waterproof and impact resistant fireproof cable.
