Abstract

This paper aims to fabricate new superhydrophobic nanocomposite coating materials to protect the inner surfaces of the petroleum pipelines from corrosion. The batch emulsification polymerization technique (BEM) was used as a facial eco-friendly technique to prepare three hydrophobic (styrene/vinyl acetate) copolymers. The sol–gel method was used to prepare SiO2 nanoparticles (SiO2-NPs) with average size ranging from 90 to 101 nm. The functionalized SiO2-NPs were prepared using hexadecyl trimethoxy silane (HDTS) as a precursor to increasing the hydrophobicity character of the unfunctionalized SiO2-NPs. Three superhydrophobic [(styrene/vinyl acetate copolymer/functionalized SiO2 nanoparticles (SiO2NPs)] nanocomposites denoted as M1, M3, and M5 were fabricated by incorporating 1, 3, and 5 wt% of the functionalized-SiO2NPs into the styrene/vinyl acetate copolymer, respectively. The effectiveness of the fabricated nanocomposite coating materials was analyzed using contact angle measurement and transmission electron and atomic force microscopies. The results showed that the highest contact angle of 161.21o was obtained by M5-nanocomposite. The highest corrosion efficiency of 99.63% was obtained at 300 ppm concentration of M5-nanocomposite-coated solution, 298 K, and 24 days.

纳米乳液聚合技术制备超疏水纳米复合涂层材料及其在石油碳素钢管道防护中的应用
本文旨在制备新型超疏水纳米复合涂层材料,以保护石油管道内表面免受腐蚀。采用间歇乳化聚合技术(BEM)制备了三种疏水(苯乙烯/醋酸乙烯)共聚物。采用溶胶-凝胶法制备了平均粒径为90 ~ 101 nm的SiO2纳米颗粒(SiO2- nps)。以十六烷基三甲氧基硅烷(HDTS)为前驱体制备了功能化SiO2-NPs,提高了非功能化SiO2-NPs的疏水性。通过在苯乙烯/醋酸乙烯共聚物中分别加入1、3和5 wt%的功能化SiO2纳米颗粒(SiO2NPs),制备了3种超疏水纳米复合材料,分别为M1、M3和M5。采用接触角测量、透射电子显微镜和原子力显微镜对制备的纳米复合涂层材料的有效性进行了分析。结果表明,m5纳米复合材料的接触角最高,达到161.21。当m5纳米复合涂层溶液浓度为300 ppm、温度为298 K、腐蚀时间为24 d时,腐蚀效率最高,达到99.63%。
