Abstract
The invention provides a metal cladding layer transparent protective layer structure and a process method thereof. The metal cladding layer transparent protective layer consists of an oil soluble macromolecule transparent protective layer, a water soluble macromolecule transparent protective layer and a metal cladding layer which are coated from top to bottom, the protective layer structure is composed of two layers of transparent protective layers, the water soluble macromolecule transparent protective layer contacted with the surface of the metal cladding layer forms the first layer, and the oil soluble macromolecule transparent protective layer which covers on the water soluble macromolecule transparent protective layer forms the second layer. The first layer is used for preventing other organic or inorganic reagents from playing eroding and discoloring roles in the metal cladding layer; and the second layer is used for isolating the water soluble macromolecule transparent protective layer from contacting outer vapor water and liquid water, enhancing the stability of the first layer, and besides endowing the entire protection layer with corrosion resistance and wear resistance.
