  The present invention relates to a method for preparing a benzoxazine-containing resin composition and a prepreg and a laminate made therefrom. The method for preparing a benzoxazine-containing resin composition is adding an acidic filler to a benzoxazine-containing resin composition. By adding an acidic filler to the benzoxazine-containing resin composition, the present invention promotes greatly the polymerization reaction of benzoxazine and epoxy resin, reduces the curing temperature required for polymerization of benzoxazine and epoxy resin. The laminate prepared from the benzoxazine-containing resin composition, to which an acidic filler is added, has high anti-stripping stability, high glass transition temperature, low water absorption, high heat resistance, high bending strength and good processability, and can achieve low coefficient of thermal expansion.
