Abstract

The invention provides a polishing fluid for aluminum and aluminum alloy materials which includes grinding material, surface active agent, oxidizer, pH regulator, brightener and de-ionized water. The weight percentage of each component is as follows: 10 to 40 percent of grinding material, 0.01 to 0.6 percent of surface active agent, 0.5 to 10 percent of oxidizer, 1 to 6 percent of pH regulator, 1 to 15 percent of brightener and the rest is the de-ionized water; the pH value of the polishing fluid is 8 to 10; the polishing fluid can be used for the surface polishing process on the aluminum and aluminum alloy materials, can effectively reduce the surface scuffing of the aluminum alloy materials after being polished, reduce the surface coarseness of the aluminum alloy materials after being polished and improve the processing quality of the aluminum alloy materials; besides, the polishing fluid has the advantages of fastening the polishing speed, not corrupting the devices, having a high use property, and the like. The polishing fluid can also be used to stop the problems of generating alkaline fog and ammonia gas during the processing process and optimize the working environment.

Description

technology field. [0001] The invention relates to a polishing liquid, in particular to a polishing liquid for aluminum and aluminum alloy materials. Background technique [0002] At present, in the production process of aluminum and aluminum alloy products at home and abroad, the traditional "three acid" chemical polishing process is basically used to polish aluminum and aluminum alloy materials. A lot of yellow NO will be produced when polishing 2 Gas, causing air pollution in the working environment, seriously affecting the health of workers; in addition, the gas is discharged to the outside to further cause air pollution. Japanese patent Zhao 58-45380 proposes an aluminum and aluminum alloy alkaline chemical polishing solution formed by adding heavy metal salts and silicides to an aluminum chemical polishing solution containing sodium hydroxide, nitrate or nitrite, to reduce NO 2 Gas generation and pollution problems. At the same time, heavy metal salt is an inorganic b...
