More Information
Summary:The invention discloses an arc-extinguishing gas-generating material for a fuse and a preparation method thereof, the arc-extinguishing gas-generating material for the fuse comprises a core material, and a first coating layer and a second coating layer which sequentially coat the core material, the core material is carbonate, the thermal decomposition temperature of the carbonate is 200-600 DEG C, the first coating layer is hydrophobic wax, and the second coating layer is hydrophobic wax. The melting point of the hydrophobic wax is 40-90 DEG C, the second coating layer is a polymer film-forming material, and the melting point of the polymer film-forming material is 100-350 DEG C. The low-melting-point hydrophobic wax and the high-melting-point polymer film-forming material are used for sequentially coating the core material, and the hydrophobic wax and the polymer film-forming material effectively isolate invasion of external water molecules to the core material, so that the carbonate core material coated at
