Abstract

The invention discloses a quickly vitrified fireproof cable material and a preparation method thereof. According to the weight parts, the raw material of the ceramic fireproof cable material comprises 60-70 of ethane-vinyl acetate copolymer, 30-40 of polyethylene, 50-100 of ceramic filler, 0.5-2.5 of coupling agent, 80-100 of flame retardant A, 10-20 of flame retardant B, 1-2 of lubricant and 1-3of antioxidant. The preparation process of the cable material comprises the steps as follows: surface disposing of the ceramic filler, compounding, mixing, granulating, drying and the like. The fireproof cable material is polymer-based composite material and has the same behaviors (namely excellent processability and convenient construction) with normal extrusion cable insulation material under normal environment, and can be vitrified within 10 minutes under the temperature of 750 DEG C or higher; the ceramics can ensure that the normal running time of the line under the temperature of 750-950 DEG C for more than 90min.

Description

technical field [0001] The invention relates to a cable material, more specifically to a rapid ceramicization refractory cable material. Background technique [0002] With the development of society, economy and science and technology, wires and cables are used more and more in people's daily life and in high-tech fields such as aerospace and military. Modern buildings use more and more combustibles, especially in crowded places such as large luxury entertainment venues and stations. If the circuit system fails at the same time when a fire breaks out in these places, the personal and property safety of all personnel on site will face greater threats. If combustibles emit a lot of smoke, especially toxic gases, it will also cause secondary the occurrence of disasters. [0003] When a fire breaks out in some large, high-rise buildings or places, the fire causes a circuit failure, which makes the alarm, automatic door, elevator, sprinkler system, various signal transmission s...
