Abstract

The invention discloses an insulated highly-fire-retardant cable sheath material. The insulated highly-fire-retardant cable sheath material comprises, by weight, 50-70 parts of polyolefin elastomers, 20-35 parts of polytetrafluoroethylene, 10-15 parts of dioctyl phthalate, 8-14 parts of dibutyl phthalate, 12-18 parts of prednisolone sodium phosphate, 15-20 parts of diphenylphosphoryl azide, 5-13 parts of 3-pyridinecarboxylic acid magnesium salt, 3-9 parts of aluminum naphthenate, 20-30 parts of flyash, 15-25 parts of guaifenesin, 3-10 parts of trichlorovinylsilane, 9-13 parts of methylaluminoxane and 4-9 parts of 2-camphanone. The insulated highly-fire-retardant cable sheath material is excellent in fire-retardant effect and capable of better guaranteeing production and living safety.

Description

technical field [0001] The invention belongs to the field of cable sheath materials, and in particular relates to an insulating and highly flame-retardant cable sheath material and a preparation method thereof. Background technique [0002] Flame-retardant cables mainly refer to power cables that are self-extinguishing after the cable sheath burns, only after a limited distance of combustion; the use of flame-retardant cables can control the combustion within a local area, reduce the spread, and avoid causing damage to other parts of the equipment itself or the surrounding area. Further burning of other equipment to reduce losses. Therefore, research on flame-retardant cables has become a hot spot in recent years. However, the existing flame retardant materials have the disadvantages of long burning distance and long self-extinguishing time of the cable sheath. Contents of the invention [0003] Aiming at the above technical problems existing in the prior art, the presen...
