RESIN COATING METHOD USING OF NANO DIAMOND PARTICLE

摘要

A resin coating method using nano-diamond particles is provided to decrease a friction coefficient of composite coating by maximizing dispersability of a filler and junction property with polymer by using nano-diamond particles treated by silane. A resin coating method using a nano-diamond disperse solution comprises the steps of: mixing nano-diamond powder of 5~20wt.% with an organic solvent of 100wt.%; making a nano-diamond disperse solution having the grain size of 10~100nm by bead milling; adding silane compound of 0.1~1wt.% to a disperse solution of 100wt.% and then, stirring silane compound and a disperse solution at 60~70°C for 1~6 hours; making a mixed coating solution by mixing a disperse solution and an oil coating solution at the weight percent of 1:9.9~1:1.9; coating aluminum alloy with the mixed coating solution; and drying a coating layer at 200~340°C for 30~60 minutes and then, air-cooling the coating layer.
