Abstract

The invention discloses an organic coloring process for an aluminum alloy coiled material at medium temperature. The organic coloring process comprises the following steps that step 1, an unclosed aluminum alloy coiled material oxidized by a positive pole is colored; step 2, a liquid on the surface of the colored aluminum alloy coiled material is squeezed dry by a roller wheel; step 3, the aluminum alloy coiled material treated in step 2 is continuously guided into a sealing groove for sealing treatment; in the coloring treatment process, the aluminum alloy coiled material is guided into a coloring groove, the coloring groove contains 80-150 g / L of dye, 0.5-1.0 g / L of a silane coupling agent, 1.5-2 g / L of nano calcium carbonate and balance water; in the coloring treatment process, the coloring temperature is 70-80 DEG C; and the coloring time is 30-60 s. The organic coloring process for the aluminum alloy coiled material at the medium temperature has the advantages that the coloring treatment of the coiled material can be achieved, and the production efficiency of the coiled material can be comparable to the coloring efficiency of the sheet. The invention further discloses the sheet prepared by the process.

Description

technical field [0001] The invention relates to the field of aluminum alloy surface treatment, in particular to a medium-temperature organic coloring process for aluminum alloy coils and an aluminum alloy sheet. Background technique [0002] At present, the same industry generally adopts aluminum wire hangers for the coloring and sealing treatment of the aluminum alloy surface, and fixes the four corners of the required oxidized and colored aluminum plate, and then colors the pieces by soaking in the color bath in the traditional way: [0003] The specific operation method is to clamp the four corners of the aluminum plate with an aluminum wire hanger, soak one by one in the color bath liquid (fixed time) with manual or equipment manipulators, then seal and clean and dry, and finally still cut due to hanging Poor coloring caused by positional contact. Each hanger occupies a position of about 30mm, and is finally cut and removed in the finished product state, resulting in un...
