The invention discloses anti-scratching extra-hard glass and a preparation method thereof, relating to the improvement and development of amorphous carbon nitride in the manufacturing field of glass. The anti-scratching extra-hard glass comprises a glass substrate, wherein a buffer nanolayer is arranged on the glass substrate, a nanometer transition layer is arranged on the buffer nanolayer, and a carbon nitride nanolayer is arranged on the nanometer transition layer. According to the anti-scratching extra-hard glass, as aluminum oxide and carbon nitride are taken as the transition layer of the glass substrate, the adhesive force of a membrane layer is increased; by buffering the internal stress of aluminum oxide or carbon nitride by virtue of silicon dioxide, the stress difference between the membrane layer in the front part and a carbon nitride layer can be decreased, the rigidity and the adhesive force of the membrane layer are improved, and the abrasive resistance of the membrane is enhanced; the phenomena that a thin layer is broken and falls off and the transmittance of a carbon nitride structural layer system is low caused by the large stress difference between a substrate and layer materials after the carbon nitride structural layer system is plated are solved; the Moh's hardness measurement reaches a level 6.5, and good anti-reflection and anti-scratching effects are achieved.
