Embodiment 1

[0029] 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.

[0030] Polishing method: Add 350kg of zirconium beads, 200mL of the above metal polishing solution and an appropriate amount of water into a 300L vibration 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

[0032] Metal polishing liquid preparation method: mix 12kg dodecylbenzenesulfonic acid and 6kg triethanolamine, then add 3kg alkylbenzenesulfonate sodium, 0.6kg benzaldehyde, 2kg sodium borate and distilled water to it, and then under room temperature 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%, triethanolamine 6wt%, benzaldehyde 0.6wt%, sodium borate 2wt%.

[0033] Polishing method: Add 450kg of stainless steel beads, 300mL of the above metal polishing solution and an appropriate amount of water into a 300L vibration 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

[0035] 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%.

[0036] Polishing method: Add 550kg 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 field of application of a metal polishing solution. A preparation method of the metal polishing solution comprises the following steps: uniformly mixing 8-15 part of organic acid and 4-7 parts of organic alkali by weight, adding 2-5 parts of surfactant, 0.2-1 part of water-soluble organic bright assistant and 1-3 parts of inorganic salt by weight in the mixture, and adding water to stir so as to obtain the metal polishing solution, wherein the metal polishing solution mainly comprises the surfactant, the organic acid, the organic alkali, the water-soluble organic bright assistant and the inorganic salt and has the pH of 6-8. The adding of all the components and the polishing operating process are carried out according to the strict sequence. The surface brightness and definition of a metal workpiece polished by adopting the metal polishing solution reach the mirror plane effect, so that the production cost is greatly reduced. The safety protection requirements to employees during the production process are low, the corrosion to equipment is small, and the environmental pollution is greatly reduced by adopting the metal polishing solution.

Description

technical field [0001] The invention relates to the preparation of a metal polishing liquid, in particular to the preparation of 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...
