Yttrium-containing rare earth polishing solution and preparation method thereof

The invention discloses a yttrium-containing rare earth polishing solution. The yttrium-containing rare earth polishing solution comprises the following components by mass percentage: 10-50% of yttrium-containing rare earth polishing powder, 0.3%-1.5% of a dispersing agent, 0.5%-3% of an anti-hardening agent, 0.2%-5% of a synergist and the balance of a solvent; and a PH value of the polishing solution is 7.5-9.5. The yttrium-containing rare earth polishing solution, as a grinding material, is mainly used for polishing glass of a cover plate of a mobile phone and other optical lenses. 种含钇稀土抛光液，包括含钇稀土抛光粉、分散剂、抗板结剂、增效剂和溶剂；其中，各组分的质量百分含量为：含钇稀土抛光粉为10~50%，分散剂为0.3%~1.5%，抗板结剂为0.5%~3%，增效剂为0.2%~5%，余量为溶剂；所述抛光液PH为7.5~9.5。本发明作为研磨材料，主要用途为手机盖板玻璃抛光及其它光学镜头的抛光。
