Abstract
Disclosed are a halogen-free resin composition, and a prepreg and a laminate prepared by using the same. The halogen-free resin composition comprises the following components according to organic solid matters by weight parts: (A) 40-80 parts by weight of allyl modified benzoxazine resin; (B) 10-20 parts by weight of hydrocarbon resin; (C) 10-40 parts by weight of allyl modified polyphenylene oxide resin; (D) 0.01-3 parts by weight of initiating agent; (E) 10-100 parts by weight of filler; and (F) 0-80 parts by weight of phosphoric flame retardant. The prepreg and the laminate prepared by using the halogen-free resin composition have lower dielectric constant and lower dielectric loss tangent value, higher peeling strength, higher glass transition temperature, excellent heat resistance and good flame retardant effect.
