The present invention relates to grinding tool technical fields, and in particular to the grinding tool and preparation method thereof of modified Nano Material cladding phenolic resin, the grinding tool are made of abrasive material, auxiliary packing and modified bonding agent；The modified bonding agent includes phenol-formaldehyde resin powder and modified Nano additive；Each parts by weight of raw materials array becomes: 3~30 parts of abrasive materials, 5~60 parts of auxiliary packings, 30~80 parts of phenol-formaldehyde resin powders, 0.01~10 part of modified Nano additive；The modified Nano additive is that nano material first obtains the nano material of polymer overmold modification after the processing of surface lipophilicity, then through in-situ polymerization.Products of the present invention has good self-lubrication, greatly improve grinding tool friction durability in grinding, grinding efficiency is not influenced simultaneously, it again can be with alternative abrasives, optimize formula and technique, the drawbacks of grinding tool wear time and grinding efficiency cannot be taken into account in industry thoroughly is improved, there are very big market prospects. |
