Abstract

The invention provides a porcelain enamel glaze material composition, which contains zinc oxide, diboron trioxide, zirconium oxide, silicon oxide and sodium oxide, wherein the composition also contains aluminum oxide or a compound which can generate the aluminum oxide after sintering, calcium oxide or a compound which can generate the calcium oxide after sintering, barium oxide and lithium oxide. The invention also provides a film coating material prepared from the porcelain enamel glaze material composition and a method for preparing the same. The film coating material has the advantages of better bonding force, wear resistance and corrosion resistance, and small surface roughness.

Description

technical field [0001] The invention relates to an enamel glaze composition, a coating film material prepared from the enamel glaze composition and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, while people require the diversification, personalization and multi-function of mobile phones, MP3, MP4, cameras and other electronic products and other products, they also have higher and higher requirements for the appearance of these products. For example, it is required to have a variety of colors and bright colors that are not easy to fade, smooth appearance, good hand feeling, metal texture and smooth glass, etc. Generally speaking, the appearance requirements of these products are achieved by coating the surface of the substrate, so , while realizing the appearance requirements of these products, there are also high requirements for the bonding force, wear resistance and corrosion resistance of the film layer on t...
