preparation example Construction

[0042] The present invention also provides a method for preparing a metal free-form surface polishing solution described in the above technical solution, comprising the following steps:

[0043] The liquid carrier, the dispersant, the friction agent, the thickening additive, the oxidizing agent and the surfactant are mixed according to the parts by weight, and the pH value is adjusted to obtain the metal free-form surface polishing liquid.

[0044] 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.

[0045] 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 mixing order ...

Embodiment 1

[0052] Weigh 5 kg of α-alumina with a particle size of 2 to 10 μm, add 1 kg of ethylene glycol (concentration: 5%), stir and disperse at room temperature, add 2.5 kg of water, 1 kg of modified ethyl cellulose, and 1 kg of 1% peroxide Hydrogen is made into a suspension, and after adding 1kgN-isopropyl polyacrylamide, a mixed solution is obtained, and the pH is adjusted to 2.5 with nitric acid solution, stirred evenly, and left to stand to obtain a metal free-form surface polishing liquid. The viscosity of the polishing liquid in a static state is 1.37 Pa.s.

[0053] Fix the 316L stainless steel frame on the fixture and immerse it in the prepared metal free-form surface polishing solution. The fixture drives the stainless steel frame to rotate rapidly around the main axis, and at the same time, the frame rotates at high speed perpendicular to the main axis, and polishes for 8 minutes to obtain a smooth mirror surface. No orange peel.

Embodiment 2

[0055] Weigh 5 kg of precipitated silica with a particle size of 20-30 μm, add 5 g of ethylene glycol solution (concentration: 10%), stir and disperse at room temperature, add 1 kg of polyethylene glycol (concentration: 70%), 50 g of corn Starch, add 50g of 0.5% hydrogen peroxide to make a suspension, add 50g of N-isopropyl polyacrylamide to obtain a mixed solution, adjust the pH to 3 with nitric acid solution, stir evenly, and let it stand to obtain a metal free-form surface polishing Liquid, the viscosity of the polishing liquid at rest is 1.52Pa.s.

[0056] The 316L stainless steel frame is fixed on the jig and immersed in the prepared metal free-form surface polishing solution. The jig drives the stainless steel frame to rotate rapidly around the main shaft. Orange peel phenomenon.

Abstract

The invention provides metal free-form surface polishing liquid, and belongs to the field of preparation of polishing liquid. The metal free-form surface polishing liquid provided by the invention isprepared by introducing 20-50 parts of a liquid phase carrier, 0.1-20 parts of a dispersing agent, 1-30 parts of a thickening additive, 80-120 parts of an abrasive, 1-20 parts of an oxidizing agent and 0.1- 20 parts of a surface active material, wherein the components cooperate with one other and work together to ensure a continuous polishing effect of the polishing liquid while solving the technical problems in prior art that viscosity is reduced as the temperature of a polishing system is increased during the polishing, resulting in a decrease in polishing efficiency. At the same time, a preparation method of the metal free-form surface polishing liquid, provided by the invention, is simple and convenient to operate, energy consumption is low, polishing cost is greatly reduced, and metalfree-form surface parts can be polished on a large scale.

Description

technical field [0001] The invention relates to the technical field of polishing materials, in particular to a metal free-form surface surface polishing liquid and a preparation method and application thereof. Background technique [0002] The development goal of modern manufacturing industry is the intelligent manufacturing of Industry 4.0. The crown of intelligent manufacturing is ultra-precision manufacturing, and the pearl of the crown of ultra-precision surface is the processing of ultra-precision and non-damaged surface. For example, the manufacture of ultra-large integrated circuit chips has entered the 7-nanometer manufacturing process. In this ultra-precision manufacturing process, the characteristics of the device are at the nanometer level, which is close to the human neuron system. The fabrication of state-of-the-art VLSI chips cannot be accomplished without the assurance of ultra-precise surface processing. At present, the polishing of ultra-large integrated ci...
