摘要

为了提高防腐涂料的耐腐蚀等性能并扩大伊朗岩沥青的应用范围,以基质沥青、伊朗岩沥青和环氧树脂作为成膜物质,辅以填料和各类助剂等其他成分,采用双组分工艺制备无溶剂型伊朗岩改性沥青防腐涂料,并采用交流阻抗测试、耐酸碱盐腐蚀性测试等对涂料的防腐性能进行了研究。结果表明:伊朗岩沥青在改性沥青中掺量为15%时,改性沥青的综合性能较为优异;与石油沥青防腐涂料相比,制得的伊朗岩改性沥青防腐涂料的耐腐蚀性能有显著提升,其耐酸、碱、盐浸泡腐蚀时间延长10 d以上。伊朗岩沥青防腐涂料在常温下黏度较大,涂覆温度为60 ℃左右时具有较好的涂覆效果。

Abstract

In order to improve the corrosion resistance of anticorrosive coatings and expand the application scope of Iranian rock asphalt, solentless Iranian rock asphalt anticorrosive coatings were prepared throuth a two-component process using the matrix asphalt, Iranian rock asphalt and epoxy resin as film - forming materials with the addtion of fillers, various additives and other components. The anti - corrosion properties of such coatings were studied through AC impedance test and acid, alkali and salt corrosion resistance test. Results showed that when the content of Iranian rock asphalt was 15%, the comprehensive properties of modified asphalt were best. The corrosion resistance of the prepared Iranian rock asphalt anticorrosive coating was much better than that of the petroleum asphalt anticorrosive coating. The corrosion resistance time to acid, alkali and salt immersion was prolonged by more than 10 days. The viscosity of Iranian rock asphalt anticorrosive coating was large at room temperature, and good coating effect was achieved when the coating temperature was about 60 ℃.
