Phosphorus element-containing crosslinking agents and flame retardant phosphorus element-containing epoxy resin compositions prepared therewith |
摘要 |
A flame retardant phosphorus element-containing epoxy resin composition substantially free of halogen, including: (I) a non-halogenated epoxy resin material selected from: (A) a non-halogenated phosphorus element-containing epoxy resin; (B) a mixture of: (1) a non-halogenated, non-phosphorus element-containing epoxy resin, and (2) a phosphorus element-containing compound; or (C) the reaction product of: (1) a non-halogenated epoxy resin; and (2) a phosphorus element-containing compound; or (D) a combination of two or more of components (A) to (C); and (II) (A) a multi-functional phenolic crosslinking agent having a hydroxy functionality of at least 2; (B) a material which forms a multifunctional phenolic crosslinking agent having a hydroxy functionality of at least 2, upon heating or (C) a mixture of components (A) and (B); in an amount of from about 50% to about 150% of the stoichiometric amount needed to cure the epoxy resin. Electrical laminate circuit boards having reduced flammability may be made from these compositions.
