Title: FLAME-RETARDANT POLYPHENYLENE ETHER RESIN COMPOSITION
Abstract:
The present invention relates to a flame-retardant polyphenylene ether resin composition, comprising, by weight percent: (A) 10-45% of a phosphorus-containing polyphenylene ether resin with a number-average molecular weight of 1000-6000; (B) 10-50% of an epoxy resin composition; (C) 10-50% of a cyanate ester resin; and (D) 10-30% of a soluble halogen flame retardant. The present invention adopts a phosphorus-containing polyphenylene ether resin with a low molecular weight that, when used in combination with an epoxy resin, a cyanate ester, and the like, improves the compatibility of the system and reduces a phase separation area of the system, and increases the adhesive force of a plate and enhances the toughness of the plate. The present invention adopts a soluble halogen flame retardant to further enhance the homogeneity of the resin system, and provides better uniformity, increased adhesion, and a lower dielectric constant and dielectric loss of the plate.
