Problems solved by technology

[0005] However, the disadvantages of the vitrified silicone rubber cable material are: when in use, it needs to be extruded by special extrusion equipment and needs to be vulcanized, the process is relatively complicated, and the scope of application is limited; if the cable material is made into a silicone rubber belt Wrapping it outside the wire and cable core will make the production efficiency low and the cost high, which is not conducive to industrial scale-up production

Abstract

The invention relates to a low-smoke zero-halogen ceramic fireproof cable material and a preparation method thereof. The low-smoke zero-halogen ceramic fireproof cable material is prepared from the following materials in parts by weight: an ethylene-vinyl acetate copolymer, an ethylene-alpha-olefin copolymer, maleic anhydride-grafted amorphous polyolefin, mica powder, ceramic powder, glass powder, magnesium hydroxide, calcium oxide, zinc oxide, melamine cyanurate, an antioxidant 1010, a silane coupling agent A-172, and lubricant silicone master batch; the ethylene content of the ethylene-vinyl acetate copolymer is 28-40%, and the melt flow rate is 3-5g/10min; the ethylene-alpha-olefin copolymer is a mixture of one or two of an ethylene-alpha-propylene copolymer and an ethylene-alpha-octene copolymer which are mixed according to any ratio by weight; the glass powder is low-melting-point glass powder having the melting point of 500-800 DEG C. The low-smoke zero-halogen ceramic fireproof cable material is porcelainized to change into a hard ceramic protection layer after ignition at high temperature and has certain mechanical strength, thereby ensuring normal operation of a wire and cable line.

Description

technical field [0001] The invention relates to the field of low-smoke fire-resistant cable materials, in particular to a low-smoke and halogen-free ceramicized fire-resistant cable material and a preparation method thereof. Background technique [0002] With the rapid growth of urban population, along with the continuous increase of high-rise buildings, subways, airports, stations, large hotels, supermarkets, hospitals, and large public sports, entertainment venues, and public transportation facilities, the importance of fire protection and fire safety issues has become prominent. . At present, when a fire breaks out in some large, high-rise buildings or public places, the fire will cause a circuit failure, which will cause the alarm, automatic doors, elevators, sprinkler systems, various signal transmission systems and other emergency rescue equipment to stop working, making it difficult for on-site personnel escape. At the same time, if combustibles emit a large amount ...
