Problems solved by technology

Taking chemical rust removal as an example, it mainly uses acid to react with metal oxides to remove rust products on the metal surface, which is commonly known as pickling and rust removal. Use dilute hydrochloric acid to remove rust in internal operation, but don’t soak the rusty metal in it for too long, otherwise the substance inside will also react after removing the surface rust. For example, after removing rust, the acid will react with iron. Causes waste of internal iron
Therefore, most

Embodiment 1

[0052] First, put 18 parts of organic acid, 0.8 part of dextrin, 3 parts of sodium molybdate, 1.1 part of phosphoric acid, and 60 parts of water into the mixer and stir at a constant speed for 30 minutes at room temperature;

[0053] Then put glycerin with a mass and number ratio of 8 parts into the obtained mixed solution, stir at a constant speed at room temperature for 10 minutes, and the speed of the mixer is 25 rpm;

[0054] Next, 0.06 parts by weight of the additive SI-1 was added to the obtained mixed solution, and stirred at a constant speed at room temperature for 30 minutes, and the speed of the stirrer was 25 rpm. Then get an environmentally friendly rust remover.

[0055] In the manufacturing process of the present invention, additive SI-1 is an antacid, and its main component is sodium iodide, which is a commercially available product of Tianjin Guangxing Chemical Reagent Co., Ltd., and its main function is to convert the mixed solution product in an acidic enviro...

Embodiment 2

[0090] First put 25 parts of organic acid, 1.5 parts of dextrin, 7 parts of sodium molybdate, 1.3 parts of phosphoric acid, and 70 parts of water into the mixer and stir at a constant speed for 30 minutes at room temperature;

[0091] Then put glycerin with a mass and number ratio of 12 parts into the obtained mixed solution, stir at a constant speed at room temperature for 15 minutes, and the speed of the mixer is 25 rpm;

[0092] Next, 0.08 parts by weight of the additive SI-1 was added to the obtained mixed solution, and stirred at a constant speed at room temperature for 30 minutes, and the rotation speed of the stirrer was 25 rpm. Then get an environmentally friendly rust remover.

[0093] In the manufacturing process of the present invention, additive SI-1 is an antacid, and its main component is sodium iodide, which is a commercially available product of Tianjin Guangxing Chemical Reagent Co., Ltd., and its main function is to convert the mixed solution product in an ac...

Abstract

The invention discloses an environment-friendly rust remover, comprising the following raw materials in parts by weight: 15-30 parts of organic acid, 5-15% of glycerin, 0.1-2 parts of dextrin, 0.5-10 parts of sodium molybdate, 0.5-2 parts of phosphoric acid, 45-70 parts of water and 0.05-0.1 part of SI-1 additive. The organic acid used in the invention is any one of citric acid, tartaric acid, malic acid, chlorogenic acid, oxalic acid, benzoic acid, salicylic acid and caffeic acid. The invention improves the traditional formula, the manufacturing process is advanced and the manufacturing method is simple, rapid and efficient. The invention overcomes the shortcoming that the existing rust removers pollute the environment, and the rust remover not only has good rust removing function, but also has excellent rust prevention function.

Description

technical field [0001] The invention relates to a chemical preparation for removing metal rust, in particular to an environment-friendly rust remover and a manufacturing method thereof. Background technique [0002] Any metal exposed to the air will quickly react with oxygen to form a thin oxide film on its surface, which actually prevents it from continuing to oxidize and becomes a protective film. Whether the metal will continue to react with oxygen depends on the nature of its oxide film. If the oxide film is stable, there will be no rust inside the metal (such as aluminum). However, this layer of oxide film is often easily replaced or unstable, so that air and water will penetrate the oxide layer protective film, making oxidation and corrosion continue to occur. Metals are continuously exposed to factors that cause rust. For example, most iron and iron alloys form an unstable oxide film, which is easy to fall off or be replaced by other metals. The oxidation reaction c...
