Referring to fig. 1, an embodiment of the present invention provides a high-reflectivity enameled pressed steel, including:

a substrate 1; the overglaze layer comprises an overglaze protective layer 3 arranged on the substrate 1 and a high-white overglaze reflecting layer 4 arranged on the surface of one side, far away from the substrate 1, of the overglaze protective layer 3. The high-white overglaze reflecting layer 4 has better reflectivity, the high-white overglaze reflecting layer 4 is superposed on the overglaze protecting layer 3, and the double-layer overglaze of the protecting layer 3 and the high-white overglaze reflecting layer 4 is superposed, so that the sufficient covering power of the high-white overglaze reflecting layer and the full and smooth enamel surface are ensured, and the reflectivity of the surface of the enamel steel plate is improved.

It should be noted that the high-white overglaze reflecting layer 4 is arranged on the overglaze protecting layer 3 by spraying and sintering; the substrate 1 is an enamel rigid substrate 1 and is made of zero-carbon steel, so that the high-reflectivity enamel steel plate is free of porcelain removal and porcelain exposure risks.

The high-white overglaze reflecting layer 4 is adjusted on the basis of high-white series enamel glaze, the reflectivity is more than 85%, and the high-reflectivity enamelled steel plate is bright in color tone on the surface while the high-reflectivity enamelled steel plate is guaranteed to be acid-base resistant, wear-resistant, corrosion-resistant and easy to clean, so that the use place is guaranteed to be bright for a long time, and the driving sight is not influenced. Therefore, the application range of the enameled pressed steel is expanded, and the enameled pressed steel can be hung on the wall surfaces of keels and corner connectors and plays roles in decoration, heat preservation and noise reduction on interior vertical surface decoration and exterior decoration.

In one embodiment, the high-reflectivity enameled pressed steel further includes a first ground coat layer 21 disposed on the upper surface of the substrate 1, and a second ground coat layer 22 disposed on the lower surface of the substrate 1, and the cover coat protective layer 3 is disposed on a side surface of the first ground coat layer 21 away from the substrate 1. It is understood that the first ground coat layer 21 and the second ground coat layer 22 are disposed on the substrate 1 by spray sintering, and the overglaze protection layer 3 is disposed on the first ground coat layer 21 by spray sintering; the first ground coat layer 21 and the second ground coat layer 22 can ensure that the overglaze layer and the substrate 1 are tightly combined; wherein, the first ground coat layer 21 and the second ground coat layer 22 are black.

The wavelength reflected by the surface of the overglaze protection layer 3 is 400-760 nm, that is, the overglaze protection layer 3 is white. Because the first ground coat layer 21 is black, the black color of the first ground coat layer 21 is covered by the white overglaze protection layer 3, so that the absorptivity of natural light and lighting lamp light can be reduced, the transmittance is reduced, the reflectivity of the high-white overglaze reflection layer 4 is effectively improved, and the brightness of a use place is improved.

Specifically, the thickness of the high-white overglaze reflecting layer 4 is 180-450 μm, and the thickness of the overglaze protective layer 3 is 100-300 μm. Through the double superposition of the thickness of the overglaze protective layer 3 and the thickness of the high-white overglaze reflective layer 4, the enamel overglaze reflective layer with very strong covering power and full and smooth surface is obtained, and high reflectivity of the enamel overglaze reflective layer is ensured. The reflectivity of an object is related to the degree of absorption of light by itself and the smoothness of the surface, the higher the lightness of the color, the higher the reflectivity, the better the smoothness and the higher the reflectivity.

Specifically, the substrate 1 includes a main body portion 11 and extension portions 12 extending downward along two ends of the main body portion 11, a cavity 13 is defined between the extension portions 12 and the main body portion 11, and the overglaze protection layer 3 and the high-white overglaze reflection layer 4 are both disposed on one side of the substrate 1 away from the cavity 13. A cavity 13 is formed between the main body 11 and the extending portion 12, and the cavity 13 has a good protection effect on the backing plate 5 and the second ground coat layer 22 installed inside, so that the service life is prolonged.

In addition, the high-reflectivity enameled steel sheet further includes a backing plate 5 disposed in the cavity 13, wherein the backing plate 5 is disposed on a side surface of the second ground glaze layer 22 away from the substrate 1. The backing plate 5 is an aluminum honeycomb core or a calcium silicate plate, and the backing plate 5 is connected with the second ground coat layer 22 through a sticking mode. The backing plate 5 has good rigidity and the surface bonded with the second ground coat layer 22 is flat, so that the backing plate 5 improves the flatness and rigidity of the substrate 1 through the second ground coat layer 22.

In a preferred embodiment, the high-reflectivity enameled pressed steel further comprises a sealant 6, a notch is formed between the edge of the backing and the cavity 13, and the sealant 6 is embedded in the notch. The sealant 6 is silicone sealant 6, and the sealant 6 is embedded in the notch, so that a gap between the backing plate 5 and the cavity 13 is sealed, the sealing property of the high-reflectivity enameled pressed steel is ensured, and mildew can be prevented.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
