Abstract
The present invention relates to a halogen-free resin composition and a prepreg and a laminated board prepared therefrom. The halogen-free resin composition contains the following components in parts by weight: 50-100 parts of an epoxy resin; 20-70 parts of benzoxazine; 5-40 parts of a polyphenyl ether; 5-40 parts of allyl benzene-maleic anhydride; 10-60 parts of a halogen-free flame retardant; 0.2-5 parts of a curing accelerator, and 20-100 parts of a filler. The prepreg and laminated board prepared from the halogen-free resin composition have comprehensive performances such as a low dielectric constant, a low dielectric loss, an excellent flame retardance, heat resistance, cohesiveness and moisture resistance, etc., and are suitable for use in a halogen-free high multilayer circuit board.
