Abstract:
1. A non-halogen flame retardant epoxy resin composition, comprising: (A) a silicon-containing, phosphorus-modified epoxy resin having an average epoxy equivalent of 300 to 1500 and containing phosphorus in an amount of 2 to 5% by weight, wherein the silicon-containing, phosphorus-modified epoxy resin is: a) a mixture of a non-silicon, phosphorus-modified epoxy resin and a silicon-containing compound; or b) a phosphorus-modified epoxy resin containing silicon atoms in a molecular structure thereof; (B) 20 to 100 parts by weight of a multifunctional epoxy resin, relative to the silicon-containing, phosphorus-modified epoxy resin wherein the multifunctional epoxy resin comprises a combination of tetraphenyl ethane epoxy resin and a bisphenol A novolac epoxy resin; (C) a 35 to 120% mixed curing agent of an amine curing agent and a phenolic curing agent, relative to the epoxy equivalent; and (D) 20 to 100 parts by weight of a metal hydrate inorganic flame retardant, relative to the resin composition.
