[0034] Correspondingly, as above-mentioned the preparation method of the polishing liquid that is used for zinc oxide crystal oxygen surface polishing, it comprises the following steps:
[0035] S1: Weigh a fixed amount of abrasive and add it to a fixed amount of deionized water, stir evenly, then add a fixed amount of electrolyte and surfactant, and stir evenly;
[0036] S2: Finally, add a pH regulator, adjust the pH value to 2.5-6.0, and stir well to obtain the polishing solution for polishing the oxygen surface of the zinc oxide crystal.
[0037] The abrasive of the present invention is preferably a nano-composite particle with a core-shell structure; the ionized acrylic acid derivative resin shell has good hydrophilic and lipophilic balance, which is conducive to the environmental stability of the charge, and is easy to form on the surface of the abrasive particle. The electric double layer increases the electrostatic repulsion between particles, thereby weakening the tend...
