Abstract

The invention discloses an aluminum product chemical polishing solution and a preparation method thereof, and relates to the technical field of aluminum product chemical polishing solutions. The aluminum product chemical polishing solution comprises a main material and an auxiliary material. The main material is composed of 2.1%-3.1% of citric acid, 4%-5% of sulfonic acid, 0.6%-1.2% of thiourea, 2.5%-3.6% of aluminum phosphate, 1.3%-1.6% of coconut diethanol amide, 3.2%-4.5% of nitric acid and 0.7%-1.4% of benzamide. The auxiliary material is composed of 0.35%-0.5% of a thickener, 0.31%-0.45% of a sensitizer and 0.52%-0.72% of an emulgator. The preparation method includes the following steps that S1, the raw materials are prepared; S2, the main material is prepared; S3, the solution is prepared and S4, a finished product is processed. By means of the aluminum product chemical polishing solution and the preparation method thereof, the problems that when a machine is adopted for polishing and grinding, operation is complicated and meanwhile the attractiveness of aluminum products can be greatly affected are solved, the polishing treatment technology using the polishing agent is improved, a polishing solution preparing method with the mature technology is enhanced and the using requirement standards are met.

Description

technical field [0001] The invention relates to the technical field of chemical polishing liquid for aluminum products, in particular to a chemical polishing liquid for aluminum products and a preparation method thereof. Background technique [0002] Aluminum is a chemical element. Its chemical symbol is Al and its atomic number is 13. The content of aluminum in the earth's crust is second only to oxygen and silicon, ranking third, and is the most abundant metal element in the earth's crust. Among metal varieties, it is the second largest category of metals after steel. It was not until the end of the 19th century that aluminum emerged as a competitive metal in engineering applications and was all the rage. The development of the three important industries of aviation, construction, and automobile requires that the material properties have the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new metal aluminum,...
