1. Field of the Invention
The present invention relates to a protective film structure, and more particularly to a nano protective film structure that is capable of anti-corrosion, anti-oxidation, anti-fingerprint, and anti-static electricity, and has effects of filtering, luster, hardness increase, and surface flatness.
2. Description of the Prior Art
In the conventional arts, a protective film structure mainly comprises an inorganic protective film structure and an organic protective film structure. The organic protective structure, such as paint, will be discolored and cracking under the radiation of ultraviolet light. Furthermore, the organic protective structure has capillaries, so that the waterproofing and weather fastness thereof are bad. Moreover, the organic protective structure is easy to generate static electricity and is CAPABLE OF SPARK that bring users high hazard. Although, a corrosion-resistant film can be formed by mixing a resin with a compound, such as Ti, Zr, Zn, Si, V, Al, etc, and then coated on a surface of a metal. The inorganic film in the conventional arts has some drawbacks. For example, a substrate of the inorganic film is limited to metal, and the cost of the inorganic film, the cost of the inorganic film is high, and the luster of the metal coated with the inorganic film is decreased.
In some conventional arts, a protective film is coated on a substrate by vacuum evaporation, such as CVD (Chemical Vapor Deposition) or PCD (Physical Vapor Deposition). The coating process must be executed in vacuum, and so the cost is high and the process is complicated. In addition, the protective film is often applied in conditions of high conductivity and high electromagnetic shield, and the color of the film is generally metallic color or the original color of the inorganic material. Therefore, the application thereof is restricted.
Hence, it is apparent that the conventional protective films are in need of improvement due to those many drawbacks.
In those conventional arts, the protective films have the problems mentioned above. In view of this, the present invention is to coat at least one nanoscale or microscale organic film on a substrate, and then to coat at least one nano inorganic film on the organic film.
The main objective of the present invention is to provide a protective film that is capable of anti-corrosion, anti-oxidation, anti-fingerprint, and anti-static electricity, and has effects of filtering, luster, hardness increase, and surface flatness by forming the colorless inorganic film on the organic film comprising coloring substances. Furthermore, the protective filter can be colored with any color to increase practicability, and suitable to any martial, such as substrate can be metal, alloy, or nonmetal, such as plastic.
Another objective of the present invention is to increase surface luster of the substrate by forming a transparent light layer.
Still another objective of the present invention is to increase productive efficiency and to decrease cost by forming a base layer of filler between the organic film and the substrate to increase the surface flatness. Furthermore, the surface luster is further increased.
Referring to
The substrate 1 can be plastic, metal, alloy, and so on. The organic film 2 is nanoscale or microscale film, and comprises a PU resin or UV resin, and a nanoscale or microscale coloring substance. If the surface of the substrate 1 is not even, at least one base layer 4 comprising a PU or UV resin and filler, as shown in
By forming the nano protective film structure mentioned above, the protective film is capable of anti-corrosion, anti-oxidation, anti-fingerprint, and anti-static electricity, and has effects of filtering, luster, hardness increase, and surface flatness. The protective filter can be colored with any color to increase practicability.
