Abstract

The invention discloses a metal product rustproof cleaning agent, and belongs to the technical field of surface treatment of metal products. The metal product rustproof cleaning agent is prepared by the following components in parts by weight: 5-7 parts of fatty amine polyoxyethylene ether, 4-8 parts of petroleum calcium sulfonate, 4-6 parts of N-nethyl-2-pyrrolidone, 5-7 parts of sorbitol anhydride aliphatic ester, 3-4 parts of defoaming agent, and 15-20 parts of de-ionized water. The metal product rustproof cleaning agent is strong in cleaning capacity, can guarantee better rust preventability under the condition of high humidity, cannot influence the corrosion resistance under the condition of high temperature, and is low in product foam, quick in foam removal, convenient for high-pressure spraying cleaning, safe, harmless and free of environmental pollution. The rustproof cleaning agent is long in rustproof time; and the rustproof time reaches above 180 days.

Description

technical field [0001] The invention relates to an antirust cleaning agent for metal products. The invention belongs to the technical field of surface treatment of metal products. Background technique [0002] During the machining process, parts are often stained with various dirt, such as acid, alkali, salt, dust, sweat, lubricating oil, etc., and may need to be left for a long time after cleaning. This process will cause parts to rust. Some large-scale equipment has large parts and many manufacturing processes. After one process is completed, the manufactured workpiece must be cleaned before entering the next process, otherwise the manufacturing accuracy of the next process may be affected. Due to the large size of the parts, the relatively complicated process, and the long manufacturing time, the metal parts are completely exposed to the air after cleaning with a general cleaning agent, and rust will occur after a long time, which will have an adverse effect on the equip...
