Problems solved by technology

[0006] However, the purpose of the composition for copper clad laminates in this invention patent is to improve the flame retardant performance. The method adopted is to improve the flame retardant itself, but its dosage is still relatively high, so the final copper clad laminate is only flame retardant. After being improved, the parameters or performance of its dispersion, mechanical properties, uniformity and reliability are still not well guaranteed. Therefore, the overall performance of the final copper clad laminate cannot at least meet the current high frequency and high speed communication. required

Abstract

The invention belongs to the technical field of communication materials, and particularly relates to a flame-retardant polyarylether-based composition. Any one or both of a double-terminal hydroxyl type phosphorus-bromine-containing polyarylether oligomer and a multi-terminal hydroxyl type phosphorus-bromine-containing polyarylether oligomer are used as matrix resin, so that when only a small amount of flame retardant is used or even no flame retardant is used in the flame-retardant polyarylether composition, the prepared prepreg and copper-clad plate can also ensure the effects of sufficient overall performance and better flame retardant property.

Description

technical field [0001] The invention belongs to the technical field of communication materials, in particular to a flame-retardant polyarylether-based composition. 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 resins, phenolic resins and cyanate ester resins have the advantages of high thermo-mechanical properties, high quality and low price, convenient processing and strong versatility, and are commonly used materials for making copper clad laminate substrates . After continuous exploration, the researchers optimized the formula composition and process parameters, and prepared various types of thermosetting copper clad laminates with qualified comprehensive properties, wh...
