Embodiment Construction
[0033] The technical solutions in the embodiments of the present invention will be apparent from the drawings in the embodiment of the present invention.
[0034] The present invention provides a composite polishing solution for a blue glass filter comprising aluminum hydroxide, zirconium hydroxide, and silica sol, and liquid base, surfactant, defoamer, and water.
[0035] The present invention also provides a method for preparing a composite polishing fluid for a blue glass filter, comprising the steps of:
[0036] (1) Add mass ratio of 5% deionized water in the reaction kettle, adding mass ratio of 40% aluminum hydroxide (γ-Al (OH) 3 Or γ-AlOOH or α-Al (OH) 3 After stirring 20 min, the control specific gravity is between 1.1-1.2, and the mass ratio of 30% is slowly added, and the mass ratio is 20% silica sol after stirring, and the mass ratio is 5% carboxus. Methylcellulose and polyethylene glycol are used as a fusion agent, stirred, warmed to 50-80 ° C for 1 hour.
