Title

EFFECT OF SONIFICATION TIME ON SYNTHESIS AND CORROSION RESISTANCE OF EPOXY-CLAY NANOCOMPOSITE

Pages

  335-346

Abstract

 In recent years many research works have been carried out on anti-corrosive NANOCOMPOSITEs coatings containing mineral reinforcements. The most important criteria in these attempts are polymerization method and the type of matrixand reinforcement of NANOCOMPOSITEs. In this regard, the physical and mechanicalproperties of the polymers in which a small amount of filler is used can be improved. Inthis research, an EPOXY-clay NANOCOMPOSITE was synthesized by in-situ polymerizationmethod using a resin matrix based on bisphenol-A type EPOXY and montmorilloniteclay (Closite (R) 15A). The treatment was used at different ultrasonic stirring times todisperse 1-4 weight percentages of CLAY particles into the matrix. The structure of synthesized EPOXY-clay NANOCOMPOSITE was studied by scanning electron microscopyand X-ray diffraction techniques. The average size of CLAY particles was determined by X-ray diffraction measurement. Then, anti-corrosion properties of EPOXY-claycoatings, prepared under different ultrasonic durations and applied on carbon steelpanels, were investigated by Tafel and electrochemical IMPEDANCE spectroscopytechniques. For this purpose, the carbon steel panels coated with these coatings were immersed in 3.5% sodium chloride solution and tested at different immersion times.The results indicated that a NANOCOMPOSITE containing 1% CLAY, synthesized, stirred60 min ultrasonically, produced smaller particle size, lower corrosion current densityand higher coating corrosion resistance than the other composite formulations. This NANOCOMPOSITE provided superior protection against corrosion in sodium chloridesolution.
