Abstract

The invention belongs to the technical field of corrosion inhibitors, and particularly relates to a ladybird rhizome extract Q235 steel corrosion inhibitor and a preparation method thereof. The invention relates to a Q235 steel corrosion inhibitor. The Q235 steel corrosion inhibitor is a ladybird rhizome extract. The white ladybird adopted in the invention is a green and pollution-free plant, and the white ladybird extract is extracted by adopting an economic and environment-friendly pure water extraction method. The pure water extraction method is simple to operate and environment-friendly. In addition, the ladybird's nettle extract has good solubility in a sulfuric acid environment, so that the ladybird's nettle extract can form a uniform and compact protective film on the surface of the Q235 steel.

Description

technical field [0001] The invention belongs to the technical field of corrosion inhibitors, and in particular relates to a Q235 steel corrosion inhibitor of Piaoerbai extract and a preparation method thereof. Background technique [0002] Q235 steel has unique physical properties, mechanical properties and economic benefits, and is widely used in industries such as oil and gas. However, the corrosion resistance of Q235 steel, especially in acidic medium, is the biggest challenge faced by the steel industry. In some industrial operations, acids are used very frequently, such as descaling and cleaning, which is potentially dangerous for severe corrosion of mild steel. In order to prolong the service life of Q235 steel and minimize the destructive and possible consequences caused by acid, the most effective way is to add corrosion inhibitor. [0003] In the prior art, inorganic corrosion inhibitors are commonly used to alleviate the corrosion of metals, such as chromate, zin...
