Problems solved by technology

In order to improve the flame retardant performance of the material, flame retardants such as antimony trioxide and zinc borate are mostly used to improve the flame retardant performance of the product, and then the greater the amount of this additive is added, the easier it is to reduce its toughness and cause the outer layer to break The phenomenon

Abstract

A preparing method of an ionic sol modified polymer flame retardant cable material is disclosed. A 1-butyl-3-methylimidazolium methanesulfonate ionic liquid, phosphonitrilic chloride trimer and silica which are adopted have good synergistic flame retardant performance. In addition, polystyrene as a heat-insulating material also has good flame retardant performance. A finished product master batch of the method has characteristics of high strength, good toughness, good flame retardance, high antibacterial activity and high stability and has excellent comprehensive performance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method of an ion sol-modified polymer flame-retardant cable material. Background technique [0002] As society pays more and more attention to fire hazards, the fire performance of cables is also required to be higher. Some special flexible cables (such as elevator cables, telecommunication device cables, etc.) Smoke and toxic and corrosive gases are dangerous factors in fires, which hinder people's safe evacuation and fire fighting work, causing serious losses of life and property. At the same time, with the development of communications, automobile industry and computer industry, Especially in many occasions such as aviation wires, automotive wires, high-temperature instrument cables, and oil drilling platform cables, it is increasingly necessary to use cable materials with flame retardant, low smoke, good thermal stability, and high thermal deformation temper...
