Abstract

The green water-base no-chromium solution for chemical aluminum material conversion consists of two components, component A and component B. The component A consists of zirconium carbonate, HF-H20, aluminum hydroxide and water; and the component B consists of titanium dioxide, HF-H20 and water. The solution is used in no-chromium phosphorizing treatment of aluminum and aluminum alloy. The solution of the present invention has low cost, low power consumption, low paint consumption, fast filming speed and high converted film quality.

Description

Technical field: [0001] The invention belongs to a chemical solution, and the invention relates to an environment-friendly aluminum material chromium-free chemical conversion water-based solution and its preparation. Background technique: [0002] Chromium phosphating treatment of aluminum is also called green film chromate treatment, the main components are phosphoric acid, chromic acid, chromate and fluoride. In the pre-painting treatment of aluminum and its alloys, the biggest source of pollution is the phosphating process, while the traditional three film-forming technologies (chromium phosphating, zinc phosphating, and chromate chromate treatment) of aluminum and its alloys use zinc Phosphating has the least toxicity and the most capacity for wastewater treatment, but the quality of the membrane layer needs to be further improved. Therefore, the development and production of chromium-free phosphating technology has become an important issue in the treatment of aluminum...
