| Zusammenfassung: | The invention relates to a method for peeling two-dimensional nano talc by using organic solvent hydrothermal/puffing, which comprises the following steps: S1, crushing: grinding talcum powder to the required particle size, such as 200-5000 meshes; s2, a hydrothermal method: weighing an organic solvent with the concentration of 30-100% and talc according to the weight ratio of 1: (0.5-1.5), sequentially pumping the organic solvent and talc into an acid reaction kettle, heating to a boiling point or above, and keeping for 1-72 hours; the invention relates to the technical field of inorganic nonmetallic mineral materials. The prepared two-dimensional nano talcum powder can be effectively applied to the field of inorganic material filling, the filling amount is large, and the strength and toughness of the material are improved.
