Abstract
The present invention relates to a colored porcelain aluminum oxide alloy decorative plate and a manufacturing method thereof. The surfaces of the forming aluminum plate materials generate one layer of oxide film by sonic waves, electrolytic degreasing, water washing, neutralization, porcelain oxidation, electrostatic painting, and computer colored grains of heat sublimation. The colored porcelain aluminum oxide alloy decorative plate which has the same shape with the porcelain glaze has the characteristics of florid color, smooth shape, no reflection, various colors and styles, no poison, burning insulation, corrosion resistance, high durability, and no harmful effects on human bodies and environment. The colored porcelain aluminum oxide alloy decorative plate has multiple varieties, such as wood grains, granite, marble series, etc., and the colored porcelain aluminum oxide alloy decorative plate is an ideal environmental protecting decorative material of a new generation. The processing steps of the present invention are reasonably designed, and membranous layers of products can not appear obvious cracks. The combined performance is favorable, and after the membranous layers are cut vertically and horizontally for many times, the membranous layers are not stripped at all. After the colored porcelain aluminum oxide alloy decorative plate is tested by neutral saline, any difference can not be generated within 500 hours, and colors can not fade at all. The acid-resistant corrosion performance is high, and after 1% of HCI is used for testing under the temperature of 25DEG C, no difference is generated within 24 hours. Compared with the indoor decorative plate in the market, the present invention has the characteristics of fire prevention, burning insulation and favorable ornamental performance.
