Abstract

The invention discloses aluminum alloy chemical polishing liquid. The aluminum alloy chemical polishing liquid is prepared by the following raw materials: 100-120 mL of phosphoric acid, 80-90 mL of glacial acetic acid, 3-4 g of 2-methylimidazole, 1-3 g of potassium peroxodisulfate, 0.5-1 g of tetramethyltetravinyl cyclotetrasiloxane, 0.5-1 g of dio-methylphenyl thiourea, 50-100 g of polyethylene glycol-4000, and 1000 g of water; and the mass percentage concentration of the phosphoric acid is 85%. Compared with the prior art, the aluminum alloy chemical polishing liquid has the advantages of environmental protection, no yellow smoke, good glossiness, uniform surface appearance, no special color, no snowflake, no excessive corrosion and convenience to use.

Description

technical field [0001] The invention belongs to the field of metal surface treatment, and in particular relates to an aluminum alloy chemical polishing liquid and a polishing method thereof. Background technique [0002] Chemical polishing is a method that relies on the chemical etching of chemical reagents to selectively dissolve the uneven areas of the sample surface to eliminate wear marks and etch leveling. The chemical polishing equipment is simple and can handle thin tubes, parts with deep holes and complex shapes, and has high production efficiency. Chemical polishing can be used as a pretreatment process for electroplating, or it can be used directly after polishing with necessary protective measures. [0003] Due to their special properties, aluminum and aluminum alloy products are widely used and occupy an extremely important position in the hardware market. Aluminum products must be polished in surface treatment, which not only makes the appearance of aluminum pr...
