[0002] Grinding and polishing processes generally include plane grinding, vibration grinding, drum grinding, eddy current grinding, magnetic grinding, etc., each with its own application characteristics. In the 3C electronics and other industries, some irregular parts (such as curved surfaces or spherical surfaces) are precisely processed to obtain surface polishing effects or to facilitate the subsequent process of obtaining better anodizing or electroplating effects. Drum grinding is used.

[0003] Wet drum grinding and polishing machine is suitable for deburring and surface polishing of hardware, ceramics, plastics, glass, such as stainless steel, magnesium alloy, zinc alloy, stamping, casting, die-casting, ceramics, jade, etc. Its operating principle is that in a hexagonal barrel or octagonal grinding barrel, with driving force, the appropriate amount of workpiece and the appropriate amount of abrasive rotate in the drum to produce an avalanche motion to achieve a strong grinding effect.

[0004] The use of drum grinding and polishing liquid between the workpiece and the abrasive can improve the grinding efficiency and obtain a better grinding effect. However, the surface grinding and polishing effect of the existing drum grinding and polishing liquid and the yield rate of the products after grinding and polishing still have a lot of room for improvement. Summary of the invention

[0012] Preferably, the friction modifier is one or a combination of monoethanolamine borate, diethanolamine borate, triethanolamine borate.

[0013] Preferably, the electrolyte is a combination of one or more of aluminum nitrate, sodium nitrate and potassium nitrate.

[0014] Preferably, the rheological additive is one or a combination of two of hydroxymethyl cellulose, polyvinyl alcohol (PVA) and fatty acid amide.

[0015] The present invention further proposes a method for preparing a drum grinding and polishing liquid, comprising the following steps:

[0016] (1) Add a wetting agent, a brightener, a surfactant, a friction modifier, an electrolyte, and deionized water to a reaction container in sequence, and stir evenly to obtain a mixed solution;

[0017] (2) The mixed solution is transferred into a blending device, and a rheological additive is added under stirring, and the mixture is stirred evenly to obtain a drum grinding and polishing liquid.
