Abstract

The invention provides an aluminium alloy polishing solution. The aluminium alloy polishing solution is prepared from the following raw materials by weight: 92.5-97 parts of a silica sol, 1-2.5 parts of a stabilizer, 1-2.5 parts of an active agent and 1-2.5 parts of a synergist. A preparation method of the aluminium alloy polishing solution comprises the following steps of removing metal ions and other impurities from a silica sol raw material by adopting a 100 nano-scale ceramic membrane filtration system; adding the filtrated silica sol into a sealed reaction tank under a vacuum negative pressure state; adding the stabilizer, the active agent and the synergist into the sealed reaction tank under the vacuum negative pressure state; stirring thoroughly; and mixing uniformly to prepare a finished product of the aluminium alloy polishing solution. The prepared aluminium alloy polishing solution has the advantages of no corrosion, small usage amount, low cost, few scratches and high polishing rate. Besides, compared with a conventional acid polishing solution, the aluminium alloy polishing solution has no pollution and can be recycled easily.

Description

Technical field [0001] The invention relates to the technical field of aluminum alloy polishing, in particular to an aluminum alloy polishing liquid and a preparation method thereof. Background technique [0002] Aluminum alloy is a good structural material, with good mechanical and physical properties and chemical stability at high temperatures. Therefore, with the development of mobile phone shells, notebook computer shells, electronic equipment, mechanical equipment, automobiles and precision parts related industries With the development, the demand for aluminum alloy materials is increasing, and it has a wide range of application prospects. [0003] In addition, due to its lighter specific gravity, high strength, easy processing, stable size, excellent process performance, good corrosion resistance, low cost, and recyclability, aluminum alloy is known as a green engineering metal in the 21st century. Replaces steel alloys in many places. [0004] With the wide application of al...
