Aluminum hanging piece with excellent surface corrosion resistance

Abstract

The utility model discloses an aluminum hanging piece with excellent surface corrosion resistance, which comprises an aluminum hanging piece body, the aluminum hanging piece body comprises a substrate layer, an inner protection layer is arranged on the outer side of the substrate layer, the inner protection layer comprises an aluminum oxide coating and a hafnium oxide coating, an outer protection layer is arranged on the outer side of the inner protection layer, and the outer protection layer is arranged between the aluminum oxide coating and the hafnium oxide coating. And the outer protection layer comprises a polytetrafluoroethylene coating and a polyvinyl chloride coating. The aluminum hanging piece is provided with the outer protection layer, the polyvinyl chloride coating of the outer protection layer can perform a first layer of corrosion-resistant protection treatment on the outer side of the aluminum hanging piece body, the polytetrafluoroethylene coating can perform a second layer of corrosion-resistant protection treatment on the outer side of the aluminum hanging piece body after the polyvinyl chloride coating is damaged, and the inner protection layer is arranged to perform a second layer of corrosion-resistant protection treatment on the outer side of the aluminum hanging piece body. The integral fire resistance of the aluminum hanging piece body can be improved through the hafnium oxide coating, the integral oxidation resistance of the aluminum hanging piece body can be improved through the aluminum oxide coating, and the integral service life of the aluminum hanging piece body is effectively prolonged through matching of the structures.
