一种铝合金化学氧化液
摘要：
本发明涉及一种铝合金化学氧化液，其由钼酸盐、磷酸盐、氟化物、锰化合物、有机酸(盐)、水组成，溶液中钼酸盐含量为1.0～15g/L，磷酸盐含量为0.5～10g/L，锰化合物含量为0.1～3g/L，氟化物含量为0.5～5g/L，有机酸(盐)含量为0.3～5g/L；pH值在4.0～6.0之间。本发明溶液可在常温下生产，浸渍处理后可形成一层结合力良好的氧化膜。本发明所有成分均为无毒或低毒化合物，不含六价铬和铅镉等重金属，溶液所含成分无贵重金属，而且均为常规商品化产品，成本低。氧化处理后无需增加封闭工序，简化了工艺流程，生产控制方便。本发明溶液可用于铝合金型材等变形铝合金制品的氧化处理。
摘要（英）：

The present invention relates to a chemical oxidation liquid for an aluminum alloy. The chemical oxidation liquid has a pH value of 4.0-6.0 and is composed of the following components of: molybdate, phosphate, fluoride, a manganese compound, organic acid (salt) and water, wherein the molybdate content in the solution is 1.0-15 g/L, the phosphate content is 0.5-10 g/L, the manganese content is 0.1-3 g/L, the fluoride content is 0.5-5 g/L and the organic acid (salt) content is 0.3-5 g/L. The solution provided by the present invention can be produced at room temperature, and is subjected to impregnation treatment to form an oxide film with a good binding force. All components in the chemical oxidation liquid are non-toxic or low-toxicity compounds and are free of heavy metals such as hexavalent chromium, cadmium and lead, and the components in the solution are free of noble metals and are conventional commercial products, so that the cost is low. After the oxidation process, a sealing process is omitted, thus simplifying process, and the production is convenient to control. The solution provided by the present invention can be used for the oxidation treatment of deformed aluminum alloy products such as aluminum alloy profiles.
