Abstract

The invention discloses a cable material containing DOPO and cross-linked alkenyl polyaryletherketone and a preparation method thereof. In this method, two-component bisphenol monomer, difluorobenzophenone and K 2 CO 3 or Na 2 CO 3 The molar ratio is 1:1:(1.2~3) in the solvent, in N 2 Under the action of flow, react at 130-150°C for 1-5h, then react at 150-170°C for 1-10h, stop heating, naturally cool down to 80°C, add alkenyl-containing bisphenol and difluorobenzophenone in equimolar amounts , at N 2 After stirring evenly under the action of air flow, the temperature is raised to 150-160° C. for 3-20 hours to synthesize polyaryletherketone containing DOPO groups and alkenyl groups. The method is simple and easy, and a weak base is used to form a salt in the polymerization reaction, and a cable material containing DOPO and cross-linked alkenyl polyaryletherketone is synthesized. The polymer has good thermal stability, has DOPO flame retardant properties and high-temperature cross-linking of alkenyl, which improves the environmental stress cracking resistance and wear resistance of cable materials. It is used in resins such as polyaryletherketone and polyarylethersulfone. The resin has good flame retardant effect.

Description

technical field [0001] The invention relates to a cable material containing DOPO and cross-linked alkenyl polyaryl ether ketone, in particular to a preparation method containing DOPO and cross-linked alkenyl polyaryl ether ketone.
