Example Embodiment

[0016] Example one

[0017] A method for preparing an anti-rust treatment solution for the inner wall of a gearbox. The composition of the anti-rust treatment solution is calculated in weight percentage: oxalic acid 8%, triethanolamine 9%, citric acid 5%, petroleum sodium sulfonate 8%, fatty alcohol Polyoxyethylene ether 5.5%, ammonium molybdate 5%, sodium benzoate 2%, sodium hydroxide 2.5%, industrial ethanol 2%, ethylene glycol 3.5%, the balance is water; the preparation method is:

[0018] 1) Add industrial ethanol and ethylene glycol into the container, then add triethanolamine and fatty alcohol polyoxyethylene ether, stir to make it evenly dissolved;

[0019] 2) Add an appropriate amount of water in another container, then add oxalic acid, citric acid, sodium petroleum sulfonate, ammonium acid, sodium benzoate and sodium hydroxide in sequence, and stir for 3 minutes for each substance added. When the sodium hydroxide is added After stirring for 15 minutes, add the solution prep...

Abstract

The invention discloses a preparation method of a rust-proof treatment fluid for an inner wall of a gearbox. The rust-proof treatment fluid consists of the following components in percentage by weight: 8-10% of oxalic acid, 7-9% of triethanolamine, 5-7% of citric acid, 6-8% of petroleum sodium sulfonate, 5.5-6.5% of fatty alcohol-polyoxyethylene ether, 3-5% of ammonium molybdate, 2-4% of sodium benzoate, 1.5-2.5% of sodium hydroxide, 2-4% of industrial alcohol, 1.5-3.5% of ethylene glycol and the balance of water. The preparation method comprises the following steps: 1) adding the industrial alcohol and the ethylene glycol into a container, and then adding the triethanolamine and the fatty alcohol-polyoxyethylene ether, and stirring to uniformly dissolve the triethanolamine and the fatty alcohol-polyoxyethylene ether; and 2) adding an appropriate amount of water into another container, then adding the oxalic acid, the citric acid, the petroleum sodium sulfonate, the ammonium molybdate, the sodium benzoate and the sodium hydroxide in sequence, stirring for 3-5 minutes, stirring for 10-15 minutes after adding the sodium hydroxide, adding a solution prepared in the step 1), then adding the rest water and uniformly stirring.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a method for preparing an antirust treatment liquid for the inner wall of a gearbox. Background technique [0002] According to information, the total amount of metal lost due to corrosion and rust in the world is more than 20% of the annual output, and the resulting economic loss is about 1 trillion US dollars. [0003] When the metal is in contact with the surrounding medium, the damage caused by chemical and electrochemical actions is called metal corrosion, and the presence of water and the formation of rust is called rust. Except for a few metals, such as gold, platinum, and titanium, all metals have a tendency to transform into ions, which means that metal corrosion is a spontaneous and ubiquitous phenomenon. [0004] After metal is corroded / rusted, it will change in appearance, color and mechanical properties, for example, causing accidents such as equipment dam...
