Abstract

The invention discloses a method for preparing a nano-graphite base abrasive substance, and belongs to the technical field of inorganic chemical materials. According to the method, firstly, ultrasonicdispersion is carried out on nano-graphite and absolute ethyl alcohol, then polyvinylpyrrolidone is added, after ultrasonic dispersion is carried out, isothermal stirring is carried out, a nano-graphite dispersion liquid is prepared, then ultrasonic mixing is evenly carried out on the nano-graphite dispersion liquid, sodium fluoride and nanometer iron powder, then precursor diluent is dropped, then an ethanol solution is dropped, isothermal stirring reaction, standing, filtering and drying are carried out to obtain a dry material; after heating high temperature reaction is carried out on thedry material under an argon shield protection state, cooling is carried out to obtain a preform body, then the preform body is washed with a hydrofluoric acid, washing and drying are carried out to obtain abrasive substance particles, lastly, after the abrasive substance particles, a ceramic adhesive agent and water are mixed, injection molding, drying, demolding, sintering and cooling are carriedout to obtain the nano-graphite base abrasive substance.
