The invention discloses a
halogen-free
flame-retardant
epoxy resin
system composition and application, the
epoxy resin
system composition is composed of an
epoxy resin part and a curing agent part, the epoxy resin part is composed of dihydroxydiphenylmethane
glycidyl ether, 2, 2 '-[(1-methylethylene) bis (4, 1-
phenylene formaldehyde)] dioxirane, 2, 2'-dihydroxydiphenylmethane
glycidyl ether, 2, 2 '-[(1-methylethylene) bis (4, 1-
phenylene formaldehyde)] dioxirane, 2, 2'-dihydroxydiphenylmethane, 2, 2 '-dihydroxydiphenylmethane, the
halogen-free
flame retardant is composed of hydroxyl-terminated polysiloxane modified
bisphenol A
glycidyl ether, an organophosphorus
flame retardant, an active
diluent and an auxiliary agent. And the curing agent part consists of an alicyclic amine curing agent, amine-terminated polyether and an
accelerant. The epoxy resin
system composition provided by the invention is low in mixing
viscosity and strong in
operability, a cured product has excellent
toughness and
heat resistance while ensuring that the flame retardant grade meets UL94V0, and the problems that a
halogen-free flame-retardant system is poor in process
operability, the performance of the cured product is reduced, halogen elements can release harmful gas at high temperature, and the service life of the cured product is prolonged can be effectively solved. And harm to
human health and environment is caused.
