Abstract

The invention discloses a soft flame retardant cable material. The soft flame retardant cable material comprises the following raw materials by weight: 30-40 parts of polyolefin resin, 15-28 parts ofrecycled polyethylene, 13-25 parts of high impact resistant polypropylene, 8-15 parts of vinisol, 5-10 parts of hollow glass microsphere, 4-9 parts of coated nanometer fly ash, 2-3 parts of plasticizer, 5-10 parts of nanometer calcium carbonate, 1-3 parts of zinc stearate, 2-4 parts of trioctyl trimellitate, 1-2 parts of dioctyl sebacate, 2-4 parts of barium stearate, 3-6 parts of triethyl citrate, 1-2 parts of antioxidant, and 5-10 parts of aluminum hydroxide. The soft flame retardant cable material is relatively low in cost, the performance meets the standard request, and the problems that alarge quantity of toxic smoke and corrosive gases produced in the combustion of the existing flame retardant cable in the fire disaster greatly damage survivors and rescue workers and pollute the environment are solved.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to a soft flame-retardant cable material and a preparation method thereof. Background technique [0002] Power supply has become an indispensable part of the rapid development of the world economy, and wires and cables, as the carrier of power supply, pervade all walks of life. Since the polymer insulation materials used in wires and cables are flammable materials, the cables are often burned due to internal factors (cable self-heating, short circuit, etc.) and external factors (fire, etc.) during the transmission of electric energy, causing damage to life and property. Traditional flame-retardant cables mainly use halogen-containing polymers (such as PVC) and halogen-containing flame retardants (chlorine- or bromine-containing compounds) to obtain good flame-retardant properties through mixing, but fires still cause cables to burn, and cables A large ...
