Abstract

The invention discloses a preparation method of a thin-wall high-temperature-resistant radiation-resistant flame-retardant cable material, namely, polyether-ether-ketone. The method comprises the following steps: placing a three-component bisphenol monomer, difluorobenzophenone, and K2CO3 or Na2CO3 into an organic solvent according to a molar ratio of 1:1:(1.2-2.0), conducting reacting at 130-150DEG C for 1-5 hours under the action of N2 flow, and the conducting reacting at 150-170 DEG C for 3-20 hours to prepare the thin-wall high-temperature-resistant radiation-resistant flame-retardant cable material polyether-ether-ketone. The method is simple and easy to implement, and the thin-wall high-temperature-resistant radiation-resistant flame-retardant cable material polyether-ether-ketone is prepared by adopting a stepwise polymerization method. The cable material prepared by the invention has the characteristics of high strength, high wear resistance, high oil resistance, high-temperature resistance, radiation resistance, good electrical insulation property, low smoke, no halogen, flame retardancy and the like, is very suitable for extrusion of ultrathin-wall cables, can meet the processing technology of ultrathin-walled insulated cables and the technical requirements of products, is convenient to produce, and has good economic benefits and popularization values.

Description

technical field [0001] The invention relates to the technical field of polyetheretherketone, in particular to a thin-walled high-temperature-resistant radiation-resistant flame-retardant cable material polyetheretherketone and a preparation method thereof.
