摘要 | Linear phenolic-epoxy polymers were cured with diaminodiphenyl sulfone (DDS), metaphenylene diamine (m-DPA), and phenolic aldehyde amine (PAA), respectively, to prepare several anti-corrosion materials that are coating components. The effect of different curing agents on energy of activation (E(alpha)) and glass transition temperature (T) of polymers was investigated using differential scanning calorimetry (DSC). E(alpha) of phenolic-epoxy/DDS is higher than that of phenolic-epoxy/PAA, and lower than that of phenolic-epoxy/m-DPA. The three anti-corrosion materials were immersed in 10% sulfuric acid (H(2)SO(4)) solution at 80 degrees C for 800 h. T(g) of phenolic-epoxy/DDS material varies very little before and after acid immersion testing. while T(g) of phenolic-epoxy/PAA material drastically decreases after the acid immersion test. A gravimetric liquid sorption experiment indicates that weight loss of phenolic-epoxy/DDS material is the smallest among three anti-corrosion materials. X-ray photoelectron spectroscopy (XPS) analysis demonstrates that the carbon-to-oxygen (C/O) ratio of phenolic-epoxy/DDS material after exposure testing is higher than that of phenolic-epoxy/m-DPA material and phenolic-epoxy/PAA material. The high T(g), high C/O ratio, and low weight loss of phenolic-epoxy/DDS material as a coating component during exposure are connected directly with the strong corrosion resistance of the coating. |
