AI Technical Summary

Problems solved by technology

[0002] The metal will inevitably be oxidized to a certain extent during the long-term contact with the air, which will cause the metal to lose its metallic luster. Therefore, before use, although the existing polishing agent can remove the oxide layer on the metal surface, the polished metal If anti-corrosion treatment is not carried out, the polished metal surface will be oxidized soon and lose its metallic luster

Embodiment 1

[0011] A polishing slurry consisting of 1 kg of alumina polishing powder (α-Al with a particle size of 4 to 15 μm 2 o 3 ), 0.1 kg of 3-aminopropyltrimethoxysilane (CAS: 13822-56-5), 0.3 kg of octadecyltriethoxysilane (CAS: 7399-00-0), 0.2 kg of hard Fatty acid, 0.1 kilogram of glycerol, 0.01 kilogram of phosphoric acid, 0.01 kilogram of sodium dodecylsulfonate and 8.28 kilograms of water are ground and mixed uniformly to obtain.

Embodiment 2

[0013] A polishing slurry consisting of 2 kg of alumina polishing powder (α-Al with a particle size of 10-25 μm 2 o 3 ), 0.1 kg of 3-aminopropyltrimethoxysilane, 0.2 kg of octadecyltriethoxysilane, 0.3 kg of stearic acid, 0.1 kg of glycerol, 0.1 kg of phosphoric acid, 0.05 kg of Sodium dodecyl sulfonate and 7.15 kilograms of water are obtained after grinding and mixing uniformly.

Embodiment 3

[0015] A polishing slurry consisting of 3 kg of alumina polishing powder (α-Al with a particle size of 25-50 μm 2 o 3 ), 0.3 kg of 3-aminopropyltrimethoxysilane, 0.1 kg of octadecyltriethoxysilane, 0.01 kg of stearic acid, 0.2 kg of glycerol, 0.05 kg of phosphoric acid, 0.03 kg of Nonylphenol polyoxyethylene ether NP-10 and 6.31 kg of water are obtained after grinding and mixing uniformly.

[0016] Use of the polishing slurry: use a spray gun to spray the slurry on the aluminum metal utensils to be treated until the utensils show metallic luster, leave them for 10-20 minutes, and then rinse them with water.

Abstract

The invention relates to polishing slurry. The slurry contains the following ingredients in percentage by weight: 10-30wt% of alumina polishing powder, 1-3wt% of 3-aminopropyl trimethoxysilane, 1-3wt% of octadecyl triethoxysilane, 0.1-3wt% of stearic acid, 1-2wt% of glycerol, 0.1-1wt% of phosphoric acid, 0.1-0.5wt% of surfactant and the balance of water. By adopting the polishing slurry disclosed by the invention, a layer of protective film is formed on the surface of metal while the polishing for the surface of metal is completed, so as to prevent air from oxidizing the surface of metal.

Description

technical field [0001] The invention relates to a slurry for metal surface polishing. Background technique [0002] The metal will inevitably be oxidized to a certain extent during the long-term contact with the air, which will cause the metal to lose its metallic luster. Therefore, before use, although the existing polishing agent can remove the oxide layer on the metal surface, the polished metal If anti-corrosion treatment is not carried out, the polished metal surface will be quickly oxidized and lose its metallic luster. Contents of the invention [0003] The object of the present invention is to provide a polishing slurry. [0004] In order to achieve the above object, the present invention provides the following technical solutions: [0005] A polishing slurry, containing 10-30wt% alumina polishing powder, 1-3wt% 3-aminopropyltrimethoxysilane, 1-3wt% octadecyltriethoxysilane, 0.1-3wt% % stearic acid, 1-2wt% glycerol, 0.1-1wt% phosphoric acid, 0.1-0.5wt% surfactan...
