Abstract

The invention provides a diamond grinding fluid dedicated for sapphire polishing and a preparation method thereof. The diamond grinding fluid is composed of white mineral oil, plant oil, and diamond micropowder according to a ratio of 10-40 mL: 15-45 mL: 0.3-1.2 g. Diamond micropowder is well dispersed and stably suspended in the compound dispersion system composed of white mineral oil and plant oil. The diamond grinding fluid has the advantages of high grinding efficiency, environment-friendliness, and low cost.

Description

technical field [0001] The invention relates to the technical field of sapphire polishing, in particular to a special diamond abrasive liquid for sapphire polishing and a preparation method thereof. Background technique [0002] Diamond micropowder is an ultra-fine abrasive with high hardness and good mechanical and physical properties. Its shape is spherical or ellipsoidal. It is used for grinding and polishing without scratching the object to be ground. Therefore, it has been widely used in different processing and polishing fields. Especially in the field of ultra-precision surface polishing. Diamond micropowder can be used as a polishing material for hard substances such as gemstones, and can usually be made into polishing products such as aerosols, oily or water-based liquids. Aerosols are easy to stagnate and precipitate, difficult to disperse, and have large waste, which limits their application range. . At present, more researches are on oil-based grinding fluid an...
