Abstract

The invention relates to the technical field of building materials and particularly relates to a ceramic aluminum single sheet and a preparation process of the ceramic aluminum single sheet. The ceramic aluminum single sheet comprises an aluminum alloy panel, wherein a sand-sprayed passivation layer, a chromizing pre-treatment layer and a fluorine-carbon ceramic coating are sequentially and outwardly arranged at the outer side of the aluminum alloy panel; the fluorine-carbon ceramic coating sequentially comprises a fluorine-carbon primer layer, a fluorine-carbon paint layer and a fluorine-carbon protection layer from inside to outside; a chromizing protection layer is arranged at the inner side of the aluminum alloy panel, and then the sand-sprayed passivation layer and the chromizing pre-treatment layer are arranged, and finally the fluorine-carbon ceramic coating is arranged, so that the surface of the alloy panel is cleaned and the adhesive force is strong; and the fluorine-carbon ceramic coating is firmly attached and is not easy to drop off. The preparation process of the ceramic aluminum single sheet disclosed by the invention is reliable and feasible, so that the final product ceramic aluminum single sheet has the advantages of excellent adhesive force, excellent acid resistance, excellent solvent resistance, excellent abrasion resistance, excellent impact resistance and excellent mechanical property.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a ceramic aluminum veneer and a preparation process. Background technique [0002] Most of the traditional building decoration materials are stone or gypsum board, but these decoration materials are relatively heavy, the building safety is poor, and the installation and processing performance is also poor. Aluminum veneer is widely used in the field of architectural decoration due to its excellent processing performance, light weight and low price. In recent years, with the needs of market development and the improvement of industry product grades, people have higher and higher requirements for various performances of aluminum veneers. [0003] Aluminum veneer is widely used due to its light weight. The Chinese invention patent No. ZL03229332.1 discloses a ceramic aluminum veneer building decoration material. The aluminum plate is used as the base material. The surfa...
