| titleOfInvention | A kind of polishing liquid and preparation method thereof polished for magnetic disk substrate |
| abstract | The invention discloses a kind of polishing liquid and preparation method thereof polished for magnetic disk substrate, it is characterised in that this method has following processing step：In the reactor, added by following composition mass percentage concentration, dimethicone：70 ~ 78%, hydroxy ethylidene-diphosphate：2.0 ~ 5.0%, glycerine：2.0 ~ 5.0%, stearic acid：0.5 ~ 2.0%, AlN Al 2 O 3 ‑CeO 2 MgO compounds：12 ~ 20%, each component sum is absolutely, with 200 revs/min of rotating speed, the h of stirring reaction 2 ~ 4 produces the polishing fluid of magnetic disk substrate polishing, wherein the particle diameter of abrasive material is between 20 ~ 100nm.The preparation technology is simple, and condition is easily controllable, and production cost is low, it is easy to industrialized production.Polishing process, glossiness good with liquor finish effect, no marking, flatness is high, and consumption is few, anticorrosion, easily washing. |
