Problems solved by technology

In addition, the phosphoric acid polishing agent is a strong acid solution, so the loss of aluminum after polishing is large, and a large amount of nitrogen oxides are produced during the polishing process, which pollutes the environment.
The polishing effect of non-phosphoric acid polishing agent on aluminum alloy is not as good as that of phosphoric acid polishing agent on aluminum alloy

preparation example Construction

[0019] The present invention also provides a preparation method of an aluminum alloy polishing agent, the preparation method comprising:

[0020] a. Mix sodium alkylbenzene sulfonate, polyethylene glycol rosin acid, alkylphenol polyoxyethylene ether and water, heat to 50-70°C and keep warm to prepare the first mixed solution;

[0021] b. Add sodium silicate, methyl cellulose and hydrogen peroxide to the first mixed liquid, mix and lower the temperature to 35-40°C and keep it warm to prepare the second mixed liquid;

[0022] c. Cool the second mixed solution to 15-35° C., and then add nitric acid to prepare an aluminum alloy polishing agent.

[0023] In the preparation method of the aluminum alloy polishing agent provided by the present invention, the amount of each raw material can be selected in a wide range, but in order to make the aluminum alloy treated with the aluminum alloy polishing agent have more excellent gloss, preferably, relatively In 100 parts by weight of nitr...

Embodiment 1

[0033] a. Mix 1.5g of sodium dodecylbenzenesulfonate, 15g of polyethylene glycol rosin acid, 7g of octylphenol polyoxyethylene ether and 1400g of water, heat to 60°C and keep it warm for 13min to make the first mixture liquid;

[0034] b. Add 13g of sodium silicate, 0.2g of methyl cellulose and 7.5g of hydrogen peroxide into the first mixed solution, mix and lower the temperature to 40°C and keep it warm for 8 minutes to prepare the second mixed solution;

[0035] c. Cool the second mixed solution to 25° C., and then add 100 g of nitric acid to prepare an aluminum alloy polishing agent.

[0036] d. At 25° C., soak the aluminum alloy sheet in the above-mentioned aluminum alloy polishing agent for 2.5 minutes to prepare polished aluminum alloy A1.

[0037] Table 1 shows the glossiness of the polished aluminum alloy and the detection results of whether nitrogen oxides are produced during the polishing process.

Embodiment 2

[0039] a. Mix 1 g of sodium dodecylbenzene sulfonate, 13 g of polyethylene glycol rosin acid, 6 g of octylphenol polyoxyethylene ether and 1300 g of water, heat to 50°C and keep it warm for 10 minutes to make the first mixed solution ;

[0040]b. Add 11 g of sodium silicate, 0.2 g of methyl cellulose and 7 g of hydrogen peroxide to the first mixed liquid, mix and lower the temperature to 35° C. and keep it warm for 5 minutes to prepare the second mixed liquid;

[0041] c. Cool the second mixed solution to 15° C., and then add 100 g of nitric acid to prepare an aluminum alloy polishing agent.

[0042] d. At 15° C., soak the aluminum alloy sheet in the above aluminum alloy polishing agent for 2 minutes to prepare polished aluminum alloy A2.

[0043] Table 1 shows the glossiness of the polished aluminum alloy and the detection results of whether nitrogen oxides are produced during the polishing process.

Abstract

The invention discloses an aluminum alloy polishing agent, a preparation method thereof and an aluminum alloy polishing method. The aluminum alloy polishing agent contains nitric acid, sodium silicate, sodium alkylbenzene sulfonate, polyethylene glycol rosin acid, alkyl Phenol polyoxyethylene ether, methyl cellulose, hydrogen peroxide and water; Wherein, with respect to the nitric acid of 100 weight parts, the content of described sodium silicate is 11-16 weight part, the sodium alkylbenzene sulfonate The content is 1-2 parts by weight, the content of the polyethylene glycol abietic acid is 13-18 parts by weight, the content of the alkylphenol polyoxyethylene ether is 6-9 parts by weight, the methyl cellulose The content of the hydrogen peroxide is 0.2-0.3 parts by weight, the content of the hydrogen peroxide is 7-8 parts by weight, and the content of the water is 1300-1500 parts by weight. The aluminum alloy polishing agent has no harmful gas emission during the aluminum alloy polishing process and the polished aluminum alloy has excellent glossiness.

Description

technical field [0001] The invention relates to a polishing agent, in particular to an aluminum alloy polishing agent, a preparation method thereof, and an aluminum alloy polishing method. Background technique [0002] At present, there are two main types of chemical polishing agents for aluminum alloys: acidic solutions and alkaline solutions. Alkaline polishing agent is a strong alkaline solution, its main component is sodium hydroxide, the operating temperature is high, usually above 100°C, the alkali fog is severe during polishing, affecting the operating environment, it is severely corroded to aluminum, the metal loss is serious, and the light output speed It is slow, and requires more concentrated acid for post-treatment to remove the black film left after alkali washing, improve the surface brightness, and more processes. [0003] Acidic polishing agents mainly include phosphoric acid polishing agents and non-phosphoric acid polishing agents. Phosphoric acid polishin...
