Embodiment 1

[0047] Preparation of performance stabilizer for magnetorheological polishing

[0048] Step 1: Add 10.0g of dispersant polyvinyl alcohol into 500ml of deionized water, and stir until the dispersant is completely dissolved;

[0049] Step 2: Continue to add 15.0g of wetting agent propylene glycol, and stir until evenly mixed;

[0050] Step 3: continue to add 8.0g of antioxidant sodium carbonate, stir well to form base carrier liquid;

[0051] Step 4: Weigh 75.0 g of cerium oxide abrasive grains, slowly add them into the stirring base carrier liquid, and keep stirring for 10 minutes to obtain a performance stabilizer for magnetorheological polishing.

Embodiment 2

[0053] Step 1: Add 5.5g of dispersant polyacrylamide into 500ml of deionized water, and stir until the dispersant is completely dissolved;

[0054] Step 2: Continue to add 15.0g of wetting agent propylene glycol, and stir until evenly mixed;

[0055] Step 3: continue to add 8.0g of antioxidant sodium carbonate, stir well to form base carrier liquid;

[0056] Step 4: Weigh 75.0 g of cerium oxide abrasive grains, slowly add them into the stirring base carrier liquid, and keep stirring for 10 minutes to obtain a performance stabilizer for magnetorheological polishing.

[0057]The difference between this example and Example 1 is that polyvinyl alcohol is used as a dispersant to prepare the cerium oxide stabilizer.

Embodiment 3

[0059] Step 1: Add 10.0g of dispersant polyvinyl alcohol into 500ml of deionized water, and stir until the dispersant is completely dissolved;

[0060] Step 2: Continue to add 15.0g of wetting agent propylene glycol, and stir until evenly mixed;

[0061] Step 3: continue to add 8.0g of antioxidant sodium carbonate, stir well to form base carrier liquid;

[0062] Step 4: Weigh 50.0 g of cerium oxide abrasive grains, slowly add them into the stirring base carrier liquid, and keep stirring for 10 minutes to obtain a performance stabilizer for magnetorheological polishing.

[0063] The difference between this embodiment and Embodiment 1 is that the content of cerium oxide abrasive particles is reduced.

[0064] 2. Effect of performance stabilizer for magnetorheological polishing on the efficiency of magnetorheological polishing

Abstract

The invention discloses a method for maintaining the polishing efficiency of a magnetorheological polishing liquid, a stabilizer and a preparation method of the stabilizer, and solves the technical problems that the polishing efficiency stability of an existing magnetorheological polishing solution is poor, and the long-time use requirement cannot be met. The stabilizer comprises the following components in percentage by mass: 12%-30% of abrasive particles, 0.5%-5% of a wetting agent, 0.05%-5% of a dispersing agent, 0.2%-3% of an antioxidant and the balance of water. The magnetorheological polishing liquid has the advantages that the polishing efficiency is stable after the stabilizer is added, and long-time use is met.

Description

technical field [0001] The invention relates to the technical field of magnetorheological polishing, in particular to a method for maintaining the polishing efficiency of magnetorheological polishing fluid, a stabilizer and a preparation method thereof. Background technique [0002] With the continuous development of modern optical technology, the demand for optical components such as large-scale optical devices, deep-space surveying and mapping equipment, and various optical scanning systems continues to rise. high demands. The traditional optical polishing processing method has small removal volume, low processing efficiency, and low precision. It is obviously difficult to meet the mass production requirements of large-scale optical engineering and modern optoelectronic systems for high-precision optical components. [0003] Magneto-rheological polishing is recognized as a revolutionary technology in optical micro-nano manufacturing, which can quickly obtain surface accur...
