Abstract

The invention belongs to the technical field of honeycomb aluminum plates and preparation processes thereof, and particularly relates to a honeycomb aluminum plate based on hot press molding and a preparation process thereof. The honeycomb aluminum plate comprises two aluminum plates and an aluminum honeycomb core sandwiched between the two aluminum plates, and the honeycomb aluminum plate is integrally formed through a hot press molding process. According to the invention, the aluminum honeycomb core is coated with the nickel layer through laser cladding, and the performance of the whole honeycomb aluminum plate is enhanced through paint spraying and chromizing treatment in various procedures of synthesizing the aluminum plate, so that the requirement of meeting more than two times of an outer wall decorative surface of a special building is met; the chromizing liquid adopted for chromizing treatment of the aluminum plate is composed of chromic nitrate, oxalic acid, cobalt salt, sodium dodecyl sulfate and borate, and has the advantages of being environmentally friendly, efficient, capable of saving energy, resistant to hard water and integrated, so that the efficiency of the preparation process is improved, the preparation process is more environmentally friendly, and the process is simpler.

Description

technical field [0001] The invention belongs to the technical field of honeycomb aluminum plate and its preparation process, in particular to a honeycomb aluminum plate based on hot pressing and its preparation process. Background technique [0002] Composite honeycomb panels are generally composed of plates and honeycomb cores, with very high strength and rigidity. It is generally used as a decorative surface for building exterior walls. [0003] The performance of the current honeycomb aluminum panels is generally the same as or close to the requirements of the standard (JG / T334-2012 "Aluminum Honeycomb Composite Panels for Building Exterior Walls", but the exterior wall decoration requirements of some special buildings are more than twice the standard, while the existing technology The performance of the honeycomb aluminum plate is not enough. Contents of the invention [0004] (1) Technical problems to be solved [0005] In order to overcome the defects in the above...
