Problems solved by technology

The disadvantage of this patent solution is: when used, it needs to be extruded by a special rubber extruder, and it needs to be vulcanized through a vulcanization process, so the process is relatively complicated and the scope of application is limited; if the cable material is made into a silicone rubber belt , and wrap it outside the cable core during the wire and cable processing process, the production efficiency is low and the cost is high, which is not conducive to industrial scale-up production; another example is the invention patent application publication number CN103525092A which provides "a kind of ceramic silicone rubber cable material and Its preparation method", formula (by weight): 80-90 parts of silicone rubber, 10-20 parts of natural rubber, 20-30 parts of mineral silicate, 10-15 parts of antimony trioxide, 10 parts of ammonium polyphosphate -20 parts, 4-6 parts of zinc oxide, 1-2 parts of antioxidant (DTPD), 20-30 parts of spray carbon black, 10-20 parts of light calcium carbonate, 14-16 parts of aluminum hypophosphite, calcium stearate 1-2 parts, 1-2 parts of pentaerythritol, 1-2 parts of talc powder and 12-14 parts of modified filler
This patent application scheme all adopts ceramic silicon rubber material like aforementioned CN101169993B, and this patent application scheme also has the des

Background technique [0002] With economic development, social progress, and significant improvement in living standards, people's awareness of safety in food, clothing, housing, transportation, and use has increased in all aspects. Among them, the safety of electricity use has become increasingly stringent. In view of the fact that wires and cables are important carriers of power systems, their safety has attracted much attention. Since the fire-resistant cable can guarantee the emergency facilities and equipment to continue to run for a certain period of time in a reasonable period of time in the burning state, it will win valuable time and / or create favorable conditions for the escape of people trapped in the fire and the rescue of firefighters. Conditions, so more by th...
