The invention discloses a method for preparing organic montmorillonite by using solid phase modified Ca-montmorillonite, specifically, the Ca-montmorillonite and a modifier or a mixed modifier are stirred for reaction at high temperature and modified to obtain the organic montmorillonite in solid phase powered state. The obtained organic montmorillonite can be directly applied to a plurality of polymer materials and can realize the intercalation of rubber macromolecule chains in mixing and vulcanizing process. Verified by mechanical property, properties of the obtained composite material, such as tensile strength, modulus, elongation at break and the like, are boosted and excellent. The method has the advantages of wide source of raw materials, handiness and feasibility, low production cost, no need of water or solvent and no environment pollution, with wide industrial application prospect.
