Problems solved by technology

[0003] At present, the glass polishing liquid used in the production of glass processing enterprises uses large particles of rare earth oxide powder as polishing friction agent, the overall polishing rate is low, the dispersion stability is poor, it is easy to cause serious surface scratches, and there are also low flattening and polishing efficiency. defect
Long-time polishing often greatly reduces the polishing efficiency, resulting in rapid wear of the polishing machine, low polishing efficiency, and a large consumption of consumables
Especially for the surface polishing process of glass free-form surface parts, individual glass parts need to be processed separately, which cannot realize large-scale glass polishing, resulting in low polishing efficiency and high cost

preparation example Construction

[0041] The present invention also provides a preparation method for the glass free-form surface surface polishing liquid described in the above technical solution, comprising the following steps:

[0042] The liquid phase carrier, the dispersant, the friction agent, the thickening additive, the oxidant and the surfactant are mixed according to the parts by weight, and the pH value is adjusted to obtain the glass free-form surface polishing liquid.

[0043] In the present invention, the mixing is preferably carried out under stirring conditions, and the stirring is preferably mechanical stirring or magnetic stirring. The present invention has no special limitation on the rotation speed and time of stirring, as long as a mixed solution can be obtained.

[0044] In the present invention, there is no special limitation on the order of adding the liquid phase carrier, dispersant, friction agent, thickening additive, oxidizing agent and surfactant; in the present invention, the mixin...

Embodiment 1

[0051] Weigh 5 kg of mixed rare earth oxides with a particle size of 2-10 μm (the mass ratio of cerium oxide and lanthanum oxide is 1:1), add 1 kg of ethylene glycol (concentration: 5%), stir and disperse at room temperature, and then add 2.5 kg of Water, 1kg modified ethyl cellulose, 1kg PVP to make a suspension, add 1kg N-isopropyl polyacrylamide to get a mixed solution, adjust the pH to 7.5 with sodium hydroxide, stir evenly, let it stand, and get a glass free-form surface Surface polishing liquid, the viscosity of the polishing liquid at rest is 2.4Pa·s.

[0052] Fix the glass ball rack on the jig and immerse it in the prepared glass free-form surface polishing solution. The jig drives the glass ball to rotate rapidly around the main axis, and at the same time, the polishing solution reversely rotates in the container, and polishes for 30 minutes to obtain a smooth mirror surface. any scars.

Embodiment 2

[0054] Weigh 5 kg of cerium oxide with a particle size of 20 to 30 μm, add 5 g of ethylene glycol solution (concentration is 10%), stir and disperse at room temperature, add 1 kg of polyethylene glycol (concentration is 70%), 50 g of corn starch , add 50gPVA to make a suspension, add 50gN-isopropyl polyacrylamide to obtain a mixed solution, adjust the pH to 7 with nitric acid, stir evenly, and leave it to stand to obtain a glass free-form surface polishing solution. The viscosity of the polishing solution in a static state is 3.1 Pa·s.

[0055] Fix the glass ball rack on the jig and immerse it in the prepared glass free-form surface polishing solution. The jig drives the glass ball to rotate rapidly around the main axis, and at the same time, the polishing solution reversely rotates in the container, and polishes for 30 minutes to obtain a smooth mirror surface. any scars.

Abstract

The invention provides a glass free-form surface surface polishing liquid, which belongs to the field of polishing liquid preparation. The glass free-form surface surface polishing liquid provided by the present invention is modified by introducing 20 to 50 parts of liquid carrier, 0.1 to 20 parts of dispersant, 1 to 30 parts of thickening additive, 80 to 120 parts of friction agent, and 1 to 20 parts of rheology. Active agent and 0.1 to 20 parts of surface active substances, the components are coordinated with each other and work together, while ensuring the continuous polishing effect of the polishing liquid, it solves the problem in the prior art that the viscosity of the polishing liquid varies with the polishing system during the polishing process. As the temperature rises, it decreases, resulting in a technical problem that the polishing efficiency decreases. At the same time, the preparation method of the glass free-form surface polishing liquid provided by the present invention is simple, easy to operate, low in energy consumption, greatly reduces the polishing cost, and does not need to use the necessary polishing pad in the traditional polishing process during the polishing process, which can realize High-volume polishing of glass components.

Description

technical field [0001] The invention relates to the technical field of polishing materials, in particular to a glass free-form surface polishing liquid, a preparation method and application thereof. Background technique [0002] The development of modern manufacturing industry has put forward higher requirements for surface precision machining. As an important means in the manufacturing and processing industry, the polishing process not only affects the performance of the product, but also affects the grade of the product. With the complexity of product structure and diversification of product portfolio, the application of polishing process is becoming more and more significant, especially for glass surface polishing process. [0003] At present, the glass polishing liquid used in the production of glass processing enterprises uses large particles of rare earth oxide powder as polishing friction agent, the overall polishing rate is low, the dispersion stability is poor, it ...
