The invention discloses a preparation method of a glass fiber cloth laminate with epoxide-group benzoxazine. The method is characterized by adding amine compounds, a solvent and an aqueous formaldehyde solution into a reactor, reacting with stirring for 1 hour, adding phenolic compounds, reacting for 3 hours under reflux, adding a catalyst and di-salt hydrogen phosphate, adding an aqueous hydrogen peroxide solution with stirring, reacting for 6-8 hours under 55-70 DEG C, cooling, standing, separating an upper organic phase as a benzoxazine resin solution with the epoxy group, putting the benzoxazine resin solution with the epoxy group, thermoplastic phenolic resin and a solvent into a glue preparing tank, stirring under 20-60 DEG C, adding anilino cyclic phosphazene and a promoter, stirring to prepare a resin glue solution, and performing coating and thermoforming for glass fiber cloth to prepare the glass fiber cloth laminate. The prepared laminate can be used for producing electrical glass fiber cloth laminates, or copper clad laminate substrate, or laminated and molded composite materials for other uses, and is good in performance.
