Corrosion Inhibitor Polymer Modified with Acid Activated Attapulgite: Preparation and Performance of Dispersing Ferric Oxide

The corrosion inhibitor modified with acid activated attapulgite (CIATP) was prepared with acid activated attapulgite (HATP), styrene sulfonic sodium (SSS), maleic anhydride (MA) as monomers, water as solvent and ammonium persulfate as initiator. The effects of mass ratio of monomer, reaction temperature, the content of initiator and reaction time of preparing CIATP were investigated. The influences of the prepared CIATP concentration, time, pH and temperature of the system on the dispersing ferric oxide efficiency were also investigated. The obtained results showed that the prepared CIATP had excellent efficiency of dispersing ferric oxide, and nearly 98.98 % of dispersing ferric oxide efficiency was obtained. The experimental results indicate the corrosion inhibitor CIATP could be used in the corrosion inhibitor of high temperature water.
