Abstract

The invention discloses a flame-retardant fire-resistant power cable material which is prepared from the following raw materials in parts by weight: 65-73 parts of methyl vinyl rubber, 38-44 parts of a maleic anhydride grafted ethylene-acetic ether copolymer, 26-30 parts of chloroprene rubber, 10-15 parts of fumed silica, 12-16 parts of mica powder, 28-33 parts of glass fiber, 15-19 parts of kaolin, 1-4 parts of ferrocene, 23-26 parts of melamine, 3-6 parts of an anti-aging agent ODA, 10-25 parts of an antioxidant 1010, 4-7 parts of 1-stearoyl-rac-glycerol, 0.2-0.5 part of chloroplatinic acid, 3-6 parts of calcium stearate, 2-4 parts of tetra-n-butyl titanate, 3-6 parts of tantalum oxide, 5-8 parts of tungsten boride and 5-9 parts of zinc borate. The invention further provides a preparation method of the flame-retardant fire-resistant power cable material. The flame-retardant fire-resistant power cable material disclosed by the invention is high in strength and very good in fire resistance, and increasingly improved requirements of the market on properties of fire-resistant power cables can be met.

Description

technical field [0001] The invention relates to the field of power materials, in particular to a flame-retardant and fire-resistant power 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] When a fire breaks out in some large, high-rise buildings or places, the fire causes a circuit failure, which makes the alarm, automatic door, elevato...
