Abstract

The invention discloses a rust prevention treatment solution for transmission case inner walls, which is composed 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 sodium petroleum sulfonate, 5.5-6.5% of fatty alcohol polyethenoxy 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.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to 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 damage and pipeline leakag...
