Problems solved by technology

[0011] Since polyaniline is insoluble in common organic solvents, it can only be dissolved in very few strong polar high boiling point solvents (such as N-methylpyrrolidone), and the adhesion of pure polyaniline film to steel is very poor
Therefore, using a large amount of pure polyaniline as an anti-corrosion coating is not very ideal either economically or from the overall performance of the coating film.

Description

technical field [0001] The invention relates to a metal anticorrosion material and a preparation method thereof, in particular to a water-based polyaniline composite metal anticorrosion material and a preparation method thereof. Background technique [0002] The surface of the metal material changes its state due to the chemical or electrochemical action of the surrounding medium (atmosphere, high temperature, molten salt, non-aqueous or aqueous medium) and transforms into a new phase, so that the metal material is damaged. This phenomenon is called It is metal corrosion. Metal corrosion is a spontaneous process and can be severe. Anti-corrosion of metal is a major problem in the global industry. The loss of steel corrosion alone is incalculable. The research on methods and materials to prevent metal corrosion is not only a major scientific issue, but also plays an important role and status in the development of national economy to establish a conservation-oriented society...
