Abstract

The invention provides steel rust removal fluid and a preparation method thereof. The steel rust removal fluid comprises the following components in parts by weight: 0.8-2.5 parts of oxalic acid, 1-7 parts of tartaric acid, 0.3-1.5 parts of lauryl sodium sulfate, 2-8 parts of phosphoric acid solution, 30-50 parts of hydrochloric acid solution, 0.2-0.9 part of fatty alcohol-polyoxyethylene ether, 0.1-0.8 part of hexamethylenetetramine, 1-5 parts of triethanolamine, 0.2-0.9 part of alkylphenol ethoxylates, 0.3-0.8 part of polyvinyl alcohol, 0.5-2.3 parts of paraffin, 0.1-1.5 parts of ammonium chloride, 0.2-2.5 parts of Tween-80, 0.5-1.5 parts of urotropine and 30-50 parts of water. The preparation method comprises the following steps: weighing the components, adding the phosphoric acid solution and hydrochloric acid solution into water, and adding other components. According to the rust removal fluid, rust on the steel surface can be removed in a short time, and the steel surface does not rust again for a long time after rust removal.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a steel derusting liquid and a preparation method thereof. Background technique [0002] With the development of the steel industry and steel manufacturing industry, the problem of steel corrosion has become increasingly prominent. The weight of metal materials and equipment scrapped due to corrosion every year in the world is about 20% to 30% of the annual output of metal, up to 1×10 8 t above. Before taking various anti-corrosion measures on metal products, rust removal is a necessary process step. The current rust removal methods mainly include mechanical methods and chemical methods. The mechanical method is manual knocking, grinding and sandblasting. The disadvantages are high labor intensity, low efficiency, serious dust pollution, and limited by the shape of the component, it is difficult to clean the rust on the edges, corners, concave corner...
