Problems solved by technology

[0007] However, the high-frequency copper-clad laminate in this invention patent uses epoxy resin as the main resin, and lacks flame-retardant treatment, so the final copper-clad laminate will have: first, the dielectric loss factor is large, and the overall dielectric The performance is poor; second, the flame retardant performance of the copper clad laminate is poor, which affects the two problems of the overall use

Abstract

The invention belongs to the technical field of communication materials, and particularly relates to a flame-retardant polyarylether-based composition and a prepreg and a thermosetting high-frequency copper-clad plate prepared from the flame-retardant polyarylether-based composition. The flame-retardant polyarylether composition is prepared by combining a necessary vinyl-terminated polyarylether oligomer, a cross-linking agent, modified resin, a filler, an initiator and an unnecessary flame retardant; and the prepreg and the copper-clad plate which are finally prepared have the advantages of outstanding flame retardance, excellent dielectric property, and overall performance meeting high-frequency communication requirements.

Description

technical field [0001] The invention belongs to the technical field of communication materials, and in particular relates to a flame-retardant polyarylether-based composition and a prepreg and a thermosetting high-frequency copper-clad laminate prepared therefrom. Background technique [0002] Copper clad laminates are widely used in mobile phones, computers, wearable devices, communication base stations, satellites, unmanned vehicles, drones and intelligent robots, and are one of the key materials in the electronic communication and information industries. Traditional thermosetting resins represented by epoxy resin, phenolic resin and cyanate resin have the advantages of high thermo-mechanical properties, high quality and low price, convenient processing and strong versatility. Common materials for substrates. [0003] However, the rapid development of electronic communication and information industry nowadays requires copper clad laminates to have more superior dielectric...
