Halogen-free flame-retardant epoxy resin composition and application thereof

摘要: The invention relates to the field of high molecular materials, in particular a halogen-free flame-retardant epoxy resin composition and application thereof. comprises 100 parts ofepoxy resin, composite flame retardant provided with diphenylphosphine oxide groups, 5-15 main retardant, 0-10 an auxiliary 2-30 curing agent 0-1 part accelerating crosslinking agent. further mixture at least two reinforced fibers, flexibilizer, filler, silane coupling solvent. containing groups is flame-retarding efficiency small adding amount has excellent compatibility dispersity resin; process, intermolecular dispersion can be realized, original transparent state maintained. finally cured advantages low cost, transparency, water absorption rate, glass conversion temperature, thermal stability, dielectric constant loss, retarding like.
