Problems solved by technology

[0003] Etched aluminum veneer is a kind of corrosion process on the surface of the aluminum alloy plate, according to the design requirements of the pattern pattern, corroded to a certain depth, retaining the pattern, and the corroded aluminum veneer is widely used in construction projects because of its beautiful appearance. Among them, through different patterns, different architectural exterior curtain walls and interior decoration styles and effects are reflected; at present, the production process of etched aluminum veneer is generally protected by etching and then spraying a certain coating material, but the coating and The aluminum veneer has insufficient bonding force and is easy to fall off. The surface coating has poor atmospheric corrosion resistance, is prone to light pollution, has poor self-cleaning performance, is not convenient for daily maintenance, and has a single color and is prone to chromatic aberration.

Abstract

The invention relates to the technical field of building materials, in particular to a fluorocarbon spray coating and etching aluminum veneer and a preparation process of the fluorocarbon spray coating and etching aluminum veneer. The fluorocarbon spray coating and etching aluminum veneer provided by the invention comprises an aluminum alloy panel with etching patterns at the outer side, wherein the outer side of the aluminum alloy panel is sequentially and outwards provided with a chromizing pretreatment layer and a fluorocarbon coating, the inner side of the aluminum alloy panel is provided with a chromizing protection layer, and the fluorocarbon ceramic coating is further arranged on the chromizing pretreatment layer, so the protection effect is realized on the surface of the aluminum alloy panel, and the adhesive force is strong, so the fluorocarbon coating is firmly attached and cannot easily fall off. The fluorocarbon spray coating and etching aluminum veneer has the characteristics that the light pollution is avoided, the self cleaning performance is high, the daily maintenance is convenient, the color is rich and cannot fade. The manufacture process of the fluorocarbon spray coating and etching aluminum veneer is reliable and is easy to implement, so the adhesive force, the acid resistance, the solvent resistance, the wear resistance, the impact resistance and the mechanical performance of the finished product fluorocarbon spray coating and etching aluminum veneer are good.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a fluorocarbon spray-etched aluminum veneer and a preparation process thereof. 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] Etched aluminum veneer is a kind of corrosion process on the surface of the aluminum alloy plate, according to the design requirements of the pattern pattern, corroded to a certain depth, retaining the...
