Problems solved by technology

[0003] Although the traditional magnesium hydroxide and aluminum hydroxide flame retardants can endow the material with good flame retardancy, however, since the matrix resin of most cable materials is a non-polar polyolefin polymer, the polar hydrogen The compatibility of magnesium oxide and aluminum hydroxide is poor, which often reduces the mechanical properties and processing properties of materials

Abstract

The invention relates to a hexaphenoxy cyclotriphosphazene-containing composite flame-retardant cable material and a preparation method thereof. The cable material adopts exaphenoxy cyclotriphosphazene, magnesium hydroxide and aluminum hydroxide as fire retardants to improve the residual rate at a high temperature and improve the thermal stability and the flame retardant property of the cable material; the cable material has the characteristic of low smoke quantity, does not contain toxic substances such as lead, antimony and the like, and is green and environment-friendly; the exaphenoxy cyclotriphosphazene can reduce the filling amount of the magnesium hydroxide and the aluminum hydroxide, improve the flame retardant property of the material and increase the mechanical property of the materials; and the lubricating agent can improve the processability of the material; and therefore, the cable material is a novel high-efficiency flame-retardant cable material.

Description

technical field [0001] The invention relates to a composite flame-retardant cable material and a preparation method thereof, in particular to a composite flame-retardant cable material containing hexaphenoxycyclotriphosphazene and a preparation method thereof. Background technique [0002] Wire and cable have the function of power transmission and information transmission, and play an important role in people's life and production. Designing and preparing low-smoke, low-toxic cable materials with excellent flame-retardant and insulating properties has become a hot spot in flame-retardant research today. [0003] Although the traditional magnesium hydroxide and aluminum hydroxide flame retardants can endow the material with good flame retardancy, however, since the matrix resin of most cable materials is a non-polar polyolefin polymer, the polar hydrogen The compatibility of magnesium oxide and aluminum hydroxide is poor, which often reduces the mechanical properties and pro...
