The present invention relates to a phosphorus-containing epoxy resin, which is an epoxy resin modified with a side chain having a reactive phosphorus-containing compound. Also, the present invention relates to a flame-retardant resin composition, which comprises:
(1) the phosphorus-containing epoxy resin,
(2) a halogen-free hardener having a reactive hydrogen capable of reacting with the epoxy group in epoxy resin, and
(3) a hardener promoter.
The flame-retardant resin composition described above has improved excellent heat resistance and flame retardant property, and is especially suitable for adhesive laminates, composite materials, printed circuit boards, adhesive material for copper foils, and is suitable for IC packaging materials.
本发明涉及一种含磷环氧树脂,它是一种用具有活性含磷化合物的侧链改性的环氧树脂。此外,本发明还涉及一种阻燃树脂组合物,它包括:
(1) 含磷环氧树脂、
(2) 不含卤素的固化剂,其活性氢能与环氧树脂中的环氧基团发生反应,以及
(3) 硬化剂促进剂。
上述阻燃树脂组合物提高了优异的耐热性和阻燃性,特别适用于粘合层压板、复合材料、印刷电路板、铜箔粘合材料,也适用于集成电路包装材料。
