Problems solved by technology

Although this kind of cleaning agent has a good cleaning effect on the grinding liquid under high temperature (about 70°C) ultrasonic conditions, it is easy to corrode some sensitive materials such as 6-series aluminum due to the presence of strong inorganic acids.

Abstract

The invention provides a grinding liquid cleaning agent excellent in cleaning effect on silica sol grinding liquid and free of corrosion effect on aluminum alloys. The grinding liquid cleaning agent comprises the components in parts by weight of 15-25 parts of sulfamic acid, 15-25 parts of surface active agent, 10-15 parts of ethylene glycol monobutyl ether, 2-10 parts of corrosion inhibitor, 10-15 parts of sodium polyacrylate, 3-12 parts of salicylic acid and 20-30 parts of water. The grinding liquid cleaning agent selects high-performance organic amine ester type surface active agents, combined salicylic acid, sulfamic acid, corrosion inhibitors-siloxane ketone, sodium polyacrylate and ethylene glycol monobutyl ether; and through a cooperation effect of the six components, the cleaning performance on silica sol by the cleaning agent is improved, and the excellent cleaning effect is still achieved under acid condition. The grinding liquid cleaning agent is obviously higher in cleaningcapacity for the silica sol at high temperature compared with a conventional weak-acidity grinding liquid cleaning agent, so that higher actual application value is achieved.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and relates to a metal surface cleaning agent, in particular to a grinding liquid cleaning agent suitable for 6 series aluminum alloys. Background technique [0002] 6-series (Al-Mg-Si) aluminum, as a medium-strength aluminum alloy with good comprehensive properties, is widely used in aerospace, transportation and construction due to its advantages such as small density, good corrosion resistance and formability. Machinery and other fields. Aluminum alloys need to use liquid abrasives during the grinding or polishing process. After grinding and sweeping, a large amount of abrasive liquid will remain on the surface of the workpiece. This type of abrasive liquid adheres very firmly to the surface of the workpiece after the surface is dried. At present, weak acid cleaning agents are generally used in the market for ultrasonic cleaning at a high temperature of about 70°C. The cleani...
