Mechanical and anticorrosion properties of organic coatings containing surface-treated talc particles depending on the dopant type
Original language description
Based on previous reaserch1, presented work is focused on surface-treated pigment base on laminated silica conductive polymer (PANI). H3PO4 was used as a primer dopant of PANI chain, diethyl phosphite (DEPH) was used as a secondary dopant which served for reprotonation of PANI salt. PANI surface layer improved paint film adhesion, physico-mechanical and anticorrosion properties of organic coatings. Talc particles were coated by conductive polymer on 10, 20 and 30 wt%. Epoxy-ester resin was used as a binder. Surface-treated pigments were then applied into this resin on 1, 5 and 10 vol% concentration. These basic coatings were applied on glass and steel panels where physico-mechanical destruction tests were made by standard. Corrosion properties were afterwards tested in an industrial enviroment containing sulfur dioxide and 100% relative humidity for 504 hours. Corrosion defects were evaluated by ASTM standards after exposition: blistering, corrosion under the paint. The result of the work was to find the most effective paint film based on mass and volume filling with a conductive polymer depending on the type of dopant the resultant organic coating was not allowed to lose adhesion after wetting, it had to prevent blistering and corrosion penetration of the metal substrate.
