The invention discloses a preparation method for an organic/inorganic hybridization cladding aluminum composite particle, which includes mixing leafing aluminum powder and solvent alcohol evenly to be transferred to a reactor to be stirred for a period of time, then adding alcoholic solution containing an organic silicon source and an inorganic silicon source at a constant speed and mixed solution of catalyst, water and alcohol, reacting for a period of time at the constant temperature, and finally filtering, washing and vacuum drying to obtain the organic/inorganic hybridization cladding aluminum composite particle. The organic/inorganic hybridization cladding aluminum composite particle has the following advantages of being capable of scattering in hydrosolvent and the alcohol solvent well and good in compatibility with resin, keeping good metal glossy, and simultaneously having good performance for resisting acid and alkaline corrosion. The organic/inorganic hybridization cladding aluminum composite particle can be used as environment-friendly metallic pigment for water-based paint.
