Abstract

The invention discloses a low-smoke flame-retardant cable material and a preparing method thereof. The material is prepared from, by weight, 20-25 parts of low-density polyethylene, 15-20 parts of ethylene-vinyl acetate copolymer, 12-18 parts of EVA resin, 45-55 parts of modified nano-magnesium hydroxide, 0.2-0.4 part of nano aluminum nitride powder, 1-2 parts of a cross-linking agent, 1-2 parts of calcium stearate, 1-2 parts of stearic acid, 0.2-0.4 part of ultraviolet light absorber UV-531, 8-15 parts of smoke inhibitor, 20-40 parts of compatilizer, 7-10 parts of a processing agent, 3-6 parts of antioxidant, 1-3 parts of a temite resisting agent and an appropriate amount of deionized water. The low-smoke flame-retardant cable material has excellent flame retardance and non-combustion-delay performance, fuming amount is small during combustion, toxic gas and corrosive gas are not generated, and the low-smoke flame-retardant cable material is good in low temperature resistance and ultraviolet resistance.

Description

technical field [0001] The invention relates to the technical field of cable production materials, in particular to a low-smoke flame-retardant cable material and a method thereof. Background technique [0002] With the rapid development of the global economy and the enhancement of human awareness of environmental protection, the requirements for the quality and performance of wires and cables in various fields are getting higher and higher, and there are more and more fires caused by the aging of wires and cables. How to reduce the fire Low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke flame-retardant cable materials is increasing. At present, most of the production of halogen-free low-smoke flame-retardant cable materials is to add a large amount of magnesium hydroxide or aluminum hydroxide to polyolefin substrates to achieve fla...
