PREPARATION METHOD FOR HIGH-REACTIVE TEFLON COATED ALUMINUM POWDER

摘要

The present invention relates to a process for preparing highly reactive Teflon-coated aluminum powder which is produced without a polymerization process. Removing the oxide film on the surface of the aluminum powder by stirring the aluminum powder in a sodium hydroxide solution and stirring the aluminum oxide powder after removing the oxide film on the surface of the aluminum powder; Attaching the particles, filtering the aluminum powder adhered with the Teflon particles in the Teflon solution, andAnd a Teflon coating step of forming a Teflon film on the surface of the aluminum powder by thermally treating the aluminum powder with the Teflon particles attached thereto. The method of claim 1, wherein the surface of the aluminum powder is coated with polytetrafluoroethylene (PTFE) Teflon coated aluminum powder is formed.;
