Embodiment 1

[0025] Metal polishing liquid preparation method: mix 8kg acetic acid and 7kg diethylamine, then add 2kg lauryl polyoxyethylene ether, 1kg PEG-600, 3kg sodium silicate and distilled water, and then stir at room temperature for 30 minutes to obtain Required metal polishing fluid. The final concentration of each component of the prepared environment-friendly metal polishing liquid is as follows: polyoxyethylene lauryl ether 2wt%, acetic acid 8wt%, diethylamine 7wt%, PEG-600 1wt%, sodium silicate 3wt% and water.

[0026] Polishing method: Add 500kg of stainless steel beads, 200mL of the above metal polishing solution and an appropriate amount of water into a 300L vibrating machine, then add the stainless steel workpiece to be polished, vibrate for 15 minutes at room temperature, and then take out the workpiece.

Embodiment 2

[0028] Preparation method of metal polishing liquid: mix 12kg dodecylbenzenesulfonic acid and 6kg triethylamine, then add 3kg sodium alkylbenzenesulfonate, 0.6kg benzaldehyde, 2kg sodium borate and distilled water, Stir for 30 minutes to obtain the desired metal polishing solution. The final concentration of each component of the prepared environment-friendly metal polishing liquid is as follows: sodium alkylbenzenesulfonate 3wt%, dodecylbenzenesulfonic acid 12wt%, triethylamine 6wt%, benzaldehyde 0.6wt%, sodium borate 2wt%.

[0029] Polishing method: Add 500kg of stainless steel beads, 300mL of the above metal polishing solution and an appropriate amount of water into a 300L vibrating machine, then add the stainless steel workpiece to be polished, vibrate for 30 minutes at room temperature, and then take out the workpiece.

Embodiment 3

[0031] Metal polishing liquid preparation method: mix 12kg ethylsulfonic acid and 6kg triethylamine, then add 3kg sodium alkylbenzenesulfonate, 0.6kg benzaldehyde, 2kg sodium borate and distilled water, then stir at room temperature for 30 Minutes to get the desired metal polishing solution. The final concentration of each component of the prepared environment-friendly metal polishing liquid is as follows: sodium alkylbenzenesulfonate 3wt%, ethylsulfonic acid 12wt%, triethylamine 6wt%, benzaldehyde 0.6wt%, sodium borate 2wt%.

[0032] Polishing method: Add 500kg of stainless steel beads, 300mL of the above metal polishing solution and an appropriate amount of water into a 300L vibrating machine, then add the stainless steel workpiece to be polished, vibrate for 30 minutes at room temperature, and then take out the workpiece.

Abstract

The invention relates to the production of an environment-friendly metal polishing liquid and relates to the field of metal polishing liquid production. The main components of the metal polishing liquid include surfactants, organic acids, organic bases, water-soluble organic brightening aids and inorganic salts, and the pH is between 6-8. The brightness and clarity of the surface of the metal workpiece polished by the polishing liquid can achieve a mirror effect, and the production cost is greatly reduced. In the production process, the requirements for the safety protection of employees are low, the corrosion of equipment is small, and the use of the polishing liquid greatly reduces environmental pollution.

Description

technical field [0001] The invention relates to a metal polishing liquid, in particular to an environment-friendly metal polishing liquid. Background technique [0002] Metal products often have burrs or a layer of gray oxide film on the surface after processing, which affects their appearance and corrosion resistance. After finishing (polishing) the surface, the surface finish and corrosion resistance can be greatly improved. At present, there are three common polishing methods: mechanical polishing, chemical polishing, and electrochemical polishing. The leveling property of mechanical polishing is good, but its labor intensity is high and the gloss retention time is not long, so it is only suitable for metal workpieces with simple structure; although the effect of electrochemical polishing is good, the cost is too high; the existing chemical polishing liquid can be It is divided into aqua regia type, sulfuric acid type and phosphoric acid type, etc. The use of chemical p...
