A method for preparing a flexible sol-gel polishing block, comprising:
- (1) adding a gel agent and an abrasive into deionized water, and stirring to even to obtain a first material, wherein the gel agent is at least one of λ carrageenan, gellan gum, sodium carboxymethyl cellulose, or konjac gum;
- (2) adding a skeleton for the gel agent into the first material obtained in the step 1, and mixing to even to obtain a second material;
- (3) injecting the second material obtained in the step 2 into a mold, and curing the mold containing the second material to obtain a cured gel;
- and
- (4) drying the cured gel to obtain the flexible sol-gel polishing block,
- wherein in the flexible sol-gel polishing block, a content of the abrasive is 9-11 wt %, a content of the gel agent is 2.9-3.1 wt %, and a content of the skeleton for the gel agent is 30-40 wt %.
