Description

technical field

[0001] The invention relates to a preparation method of a rust remover. Background technique

[0002] Due to the oxidative properties of metals, finished products that need to be made of metals are also easily oxidized, which causes inconvenience in production and use, and even shortens the service life and increases production costs. Contents of the invention

[0003] Purpose of the invention: the purpose of the present invention is to solve the deficiencies in the prior art and provide a rust remover.

[0004] Technical solution: A rust remover of the present invention comprises the following components in parts by weight: 1.5-2 parts of soda ash, 0.5-1 part of sodium phosphate, 0.2-0.5 parts of sodium benzoate, 10-15 parts of naphthenic acid, three 2-5 parts of ethanolamine, 0.1-1 part of citric acid, 0.9-1.1 parts of petroleum sulfonate, 0.5-1.5 parts of hydrogen peroxide, 20-30 parts of 85wt% phosphoric acid and 100 parts of water.
