火山灰微粒改性聚苯胺/环氧涂层的防腐蚀和耐热冲击性能

摘要

通过向聚苯胺/环氧涂层中添加适量的火山灰微米粒子（TMP），有效提高了涂层的防腐性能，同时考察了TMP含量对涂层防腐性能的影响。实验结果表明添加TMP后的涂层在95℃、12% NaCl溶液中浸泡60 d后仍具有较高的低频阻抗值；其中，添加量为10%（质量分数）的涂层的阻抗值最高，为1.27×10⁹ Ω·cm²，说明该涂层仍具有较好的防腐性能。另外，该复合涂层的附着力有所改善，并具有优异的耐热冲击性能。

Abstract：

The protective performance of polyaniline/epoxy coating was effectively improved by adding appropriate tephra micron particles (TMP). Meanwhile the effect of TMP incorporation content on protective efficiency was investigated. The experiment results indicate that impedance modulus of low frequency for coatings with TMP maintained high levels after 60 days immersion in NaCl solution (95℃, 12%). Among them coating with 10% TMP had the highest impedance modulus, 1.27×10⁹ Ω·cm², which means the coating steel had a well protective performance. In addition, the hybrid coating has improved adhesion strength and outstanding thermal shock resistance.
