CLAY-BASED COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR

A clay-based composite material, comprising the following components: 5-99.99 parts of super light clay, 0.01-95 parts of conductive filler, and 0-50 parts of lubricant; or 20-99 parts of super light clay, 1-80 parts of conductive filler, 0-30 parts of aqueous solution, and 0-70 parts of lubricant. A preparation method for the clay-based composite material comprises: (1) molding and then naturally air-drying the super light clay, or spraying or dipping or brushing the conductive filler, and performing natural air-drying for 8-96 hours; (2) putting the super light clay and the conductive filler into an agitator, with a water content being 30-75%, putting the two in a sealed container after sealed agitation, taking out the mold and naturally air-drying same. Reduction treatment of the clay-based composite material comprises: crushing the naturally air-dried clay-based composite material into particles, adding water, putting into the sealed container, placing at room temperature for 24-96 hours, taking out, stir
