[0018] The second aspect of the present invention relates to a preparation method of the polishing liquid of the present invention, the method comprising: first dissolving the abrasive and the dispersant in water, stirring uniformly, adding an oxidizing agent, and stirring uniformly, adding a pH regulator.
[0019] The third aspect of the present invention relates to a glass polishing method, which includes polishing glass with the polishing liquid described in the present invention.
Embodiment 1-7
[0022] Weigh the abrasive, dispersant and oxidant according to the content of each component in the polishing liquid. Dissolve the abrasive and dispersant in an appropriate amount of water, and perform mechanical stirring. After the dispersion is uniform, continue to add an oxidant and perform mechanical stirring. Then, add an appropriate amount of pH regulator to adjust the pH value of the polishing solution to 7-8. Obtain the alkaline polishing liquid A1-A6.
Embodiment 12-18 and comparative example 19-22
[0028] The same glasses were polished using polishing solutions A1-A7 and D1-D4 respectively, and then the following tests were performed, and the results are shown in Table 2.
[0029] Removal rate: After polishing and cleaning the glass, detect the glass surface quality and polishing rate, measure the quality difference before and after polishing with a precision balance, and calculate the removal rate.
[0030] Surface roughness: use a surface roughness tester to detect the surface roughness of the polished glass.
[0031] According to ASTM E-1820, use a universal testing machine and a Vickers hardness tester to measure glass fracture toughness K IC .
[0032] Table 2
[0033]
[0034] It can be seen from the results in Table 1 that after the glass is polished with the polishing liquid according to the present invention, the glass surface has low roughness, high removal rate and smooth glass surface. Moreover, the polishing liquid of the present invention enhances the...

Abstract
The invention relates to the field of glass manufacture, in particular to a polishing solution and a preparation method thereof. The polishing solution is prepared from an abrasive, an oxidizing agent, a dispersant and a pH regulator, wherein the solution contains, in percentage by weight on the basis of the total quantity of the abrasive, the oxidizing agent and the dispersant, 55%-80% of the abrasive, 2%-20% of the oxidizing agent and 6%-25% of the dispersant. The preparation method comprises steps as follows: the abrasive and the dispersant are dissolved in water and stirred uniformly, theoxidizing agent is added, and the pH regulator is added after the mixture is stirred uniformly. The invention also relates to a glass polishing method which comprises the step of polishing glass withthe polishing solution. The prepared polishing solution has high dispersion stability and polishing efficiency, the surface roughness of the polished glass is low, and the glass surface is flat; closecontact and interaction among compound components are enhanced through high-strength mechanical friction of the polishing solution, the synergistic interaction function of the components is sufficiently played, and the performance of the polishing solution is excellent.
Description
technical field [0001] The invention relates to the field of glass manufacturing, in particular to a polishing liquid and a preparation method thereof. Background technique [0002] Optical glass has high requirements on the surface finish of the glass. In the post-processing process, the polishing process determines the quality of the finished glass. At present, the polishing liquid on the market will have problems such as condensation, low polishing efficiency, and poor glass surface quality during use. Moreover, the suspension and dispersibility of the existing polishing liquid are relatively poor. Contents of the invention [0003] The object of the present invention is to provide a polishing liquid and a preparation method thereof in order to overcome the problems of low polishing efficiency, poor glass surface quality and poor suspension and dispersibility of the existing polishing liquid in the prior art. [0004] In order to achieve the above object, the present i...
