Wear-resistant and tear-resistant optical cable material and preparation method thereof

According to the wear-resistant and tear-resistant optical cable material and the preparation method thereof, hexagonal boron nitride and nano silicon dioxide are compounded for the first time, nano silicon dioxide doped hexagonal boron nitride mixed powder is prepared, the nano silicon dioxide doped hexagonal boron nitride mixed powder has the advantages of being good in compactness and small in porosity, and compared with the mode that hexagonal boron nitride is directly added into a base material, the wear-resistant and tear-resistant optical cable material has better wear resistance and tear resistance. The optical cable material prepared by the invention has more excellent wear resistance; then stearic acid is used for carrying out surface modification on the nano silicon dioxide doped hexagonal boron nitride powder, and the powder subjected to surface modification is added into a base material, so that the compatibility between the nano silicon dioxide doped hexagonal boron nitride powder and the base m
