Problems solved by technology

At present, the main insulating material for the production of thin-walled cables in the cable industry is cross-linked polyolefin. Because the cable material contains more flame retardants, the insulation resistance is small, the cable is easy to be broken down, and the physical and mechanical properties of the cable have many problems. Insufficient, the insulating wall cannot be ultra-thin, and it is difficult to meet the needs of manufacturing companies

Abstract

The invention relates to a preparation method of polymeric polyaryletherketone containing a DOPO side group. The preparation method comprises following steps: (1) adding dual component bisphenol, difluorobenzophenone, and a catalyst into an organic solvent (I) according to a certain mole ratio, under the action of N2 flow, carrying out reactions for two times at a controlled temperature, immediately pouring the reaction liquid into water under stirring, dialyzing the precipitates by flowing water for 24 hours, and freeze-drying the precipitates to obtain a polyaryletherketone base material containing an allyl substituent; and (2) dissolving the polyaryletherketone base material containing an allyl substituent into an organic solvent (II), under the protection of N2, slowly heating the organic solvent (II), adding mercapto- DOPO derivatives and an initiator into the organic solvent (II), carrying out reactions at a constant temperature, immediately adding the reaction system into water,dialyzing the precipitates by flowing water for 24 hours, and drying the precipitates in vacuum to obtain the polymeric polyaryletherketone containing a DOPO side group. The polymeric polyaryletherketone cable material is synthesized by click reactions and the method is simple and easy to perform. The prepared cable material has the characteristics of high strength, strong wear resistant property, strong oilproof property, good electrical insulating property, low smoke, no pollution, halogen-free property, and flame retardant performance and is suitable for prepare cables with an ultrathin wall; the cable material meets the requirements of processing technology and technique of ultrathin wall insulation cables; the production is convenient, good economic benefits are generated, and the popularization value is high.
