Manufacturing clear coated aluminum alloy lighting sheet |
摘要 |
A process for making an aluminum alloy lighting sheet product having a reflective surface protected by a UV-stable polymer coating. An aluminum alloy sheet is chemically brightened in an aqueous acidic solution, conversion coated, and then coated with a UV-stable polymer. Alternatively, an aluminum alloy sheet is chemically etched in an aqueous alkaline solution, conversion coated, and then coated with a UV-stable polymer. Preferably, the UV-stable polymer contains about 0.5-10 wt. % amorphous silica particles. In another embodiment, an aluminum alloy sheet surface is cleaned, chemically conversion coated and then coated with a coating composition containing a UV-stable polymer and 0.5-10 wt. % of about 0.5-5 microns.
