Interface processing agent and preparation method thereof
The invention provides an interface processing agent and a preparation method thereof. Cation exchange resin and a fluoric acid compound are taken as a corrosive agent, and hydrofluoric acid is generated in an aqueous solution, elements in a material is effectively corroded, the smoothness of the material interface is destroyed, the interface effective surface area is enlarged, and the adhesive force of the material surface is increased. Also, when the corrosion type interface processing agent is used, a phosphate compound, a hydrochloride compound and a nitrate compound form a mixed acid, and thus corrosion of the single acid hydrofluoric acid is avoided and corrosion acceleration effect is reached. The invention also provides a corrosion inhibition type interface processing agent and a preparation method thereof. Cation exchange resin and a fluoric acid compound are taken as a corrosive agent, the interface effective surface area is enlarged and the interface adhesive force is increased. A surfactant 1227, hexadecyl trimethyl ammonium bromide and hexadecylpyridinium bromide effectively prevent hydrofluoric acid from generating erosion and hydrogen osmosis effects on the material surface, reduce corrosion efficiency and reach corrosion inhibition effect.
