Abstract
The invention discloses a flame-retardant cable material and a preparation method for the same. The flame-retardant cable material comprises the constituents in the following parts by weight: 100 parts of HDPE (high density polyethylene), 10-30 parts of carbon black, 5-20 parts of decabromodiphenyl ether, 2-4 parts of barium metaborate, 3-7 parts of tri-(2-chloropropyl) phosphate, and 2-4 parts of melamine cyanurate. The preparation method comprises the following steps of: weighing the various raw materials in a proportioning ratio, uniformly mixing, then melting and mixing, and extruding and granulating to obtain the flame-retardant cable material. The flame-retardant cable material disclosed by the invention is good in flame-retardant performance, provided with self-extinguishment property, and can achieve an electrical resistivity of 1018 Ohm.cm, thus completely meeting the requirements of communication cable materials.
Description
technical field [0001] The invention relates to a cable material and a preparation method thereof, in particular to a flame-retardant cable material and a preparation method thereof. Background technique [0002] Cable electric cable; power cable, usually a rope-like cable twisted by several or several groups of wires, at least two in each group, each group of wires is insulated from each other, and often twisted around a center, the whole The outside is covered with a highly insulating covering. [0003] Wires and cables mainly include bare wires, electromagnetic wires and insulated wires for electrical appliances, power cables, communication cables and optical cables. Wire and cable refers to materials used for power, communication and related transmission purposes. There is no strict boundary between "wire" and "cable". Usually, products with few cores, small product diameter and simple structure are called wires, those without insulation are called bare wires, and oth...
