Abstract

The invention discloses a halogen-free flame-retardant cable material, which is composed of the following raw materials in parts by weight: 62-67 parts of methyl vinyl silicone rubber, 30-35 parts of polystyrene, 7-11 parts of fumed white carbon black, 4-7 parts of talcum powder, 5-9 parts of attapulgite, 2-5 parts of dibasic lead phosphite, 6-10 parts of tricresyl phosphate, 3-6 parts of dilauryl thiodipropionate, titanic acid 2-5 parts of tetraisopropyl ester, 2-5 parts of ultraviolet absorber UV531, 1-3 parts of anti-aging agent IPPD, 2-5 parts of antioxidant MB, 3-6 parts of polyvinylpyrrolidone, 7-parts of zinc stearate 11 parts, mica powder 5-9 parts, halloysite 3-7 parts. The invention also discloses a preparation method of the halogen-free flame-retardant cable material. The cable material prepared by the invention has excellent flame retardant performance, does not contain halogen components, does not emit toxic smoke when burning, avoids secondary disasters, and has high safety.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a halogen-free flame-retardant cable material and a preparation method thereof. Background technique [0002] With the development of society, economy and science and technology, wires and cables are used more and more in people's daily life and in high-tech fields such as aerospace and military. Modern buildings use more and more combustibles, especially in crowded places such as large luxury entertainment venues and stations. If the circuit system fails at the same time when a fire breaks out in these places, the personal and property safety of all personnel on site will face greater threats. If combustibles emit a lot of smoke, especially toxic gases, it will also cause secondary the occurrence of disasters. [0003] In order to prevent the cable from catching fire, it is necessary to improve the flame retardant performance of the cable material, reduce its flammabil...
