Abstract

The invention discloses an aluminum material chemical polishing solution and a polishing method thereof.The aluminum material chemical polishing solution is prepared by mixing an ionic liquid, an additive and water, and the using method of the aluminum material chemical polishing solution comprises the steps that the aluminum material chemical polishing solution is prepared firstly, then chemical polishing treatment is conducted on a to-be-polished aluminum material, and finally the used aluminum material chemical polishing solution is recycled. The polishing solution is treated and recycled and is used for the aluminum material polishing procedure again, repeated recycling is achieved, toxic substances such as yellow smoke and irritant gas are not generated in the using process, harm to the human body and the environment is small, meanwhile, due to the fact that the polishing solution can be recycled, low emission and low pollution are achieved, and the polishing solution is environmentally friendly. The polishing solution is composed of ionic liquid with low concentration, most of the ionic liquid is composed of water, the problem that the polishing solution is lost due to the fact that the aluminum material is attached to and taken out of the polishing solution is obviously solved in the using process, a solution in a rinsing bath can be recycled into the polishing bath after polishing and is used for chemical polishing of the aluminum material, cost is saved, and pollution to the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of polishing liquids, in particular to a chemical polishing liquid for aluminum materials and a polishing method thereof. Background technique [0002] Aluminum has the advantages of light weight, good ductility, corrosion resistance and easy plastic processing. It has been widely used in aerospace, aviation, electronics, automobiles, ships and many other fields. However, during the use of aluminum products, aluminum products will be Corrosion occurs in different degrees, and at the same time, because of its low wear resistance, the decorative and functional properties of aluminum products are not good. In order to improve this shortcoming of aluminum products, it is usually necessary to Surface treatment is carried out to improve its application value, and surface polishing is an important processing technology in the surface treatment of aluminum products, mainly including mechanical polishing, chemical po...
