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.
本发明涉及一种阻燃聚苯醚树脂组合物,按重量百分比计包括:(A)10-45%的数均分子量为1000-6000的含磷聚苯醚树脂;(B)10-50%的环氧树脂组合物;(C)10-50%的氰酸酯树脂;以及(D)10-30%的可溶性卤素阻燃剂。本发明采用了一种低分子量的含磷聚苯醚树脂,该树脂与环氧树脂、氰酸酯等配合使用时,可提高体系的相容性,减少体系的相分离面积,增加板材的粘合力,提高板材的韧性。本发明采用可溶性卤素阻燃剂,进一步提高了树脂体系的均匀性,使板材具有更好的均匀性、更强的附着力、更低的介电常数和介电损耗。
