ABSTRACT

A N, N’-methylene diacrylamide-based cross-linking copolymer film was thermally polymerised on a 6063 Al alloy using ethylene glycol maleic rosinate acrylate (EGMRA) as the cross-linking agent. The chemical structure and morphology of the copolymer films were examined by Fourier transform-infrared spectroscopy and scanning electron microscopy, respectively. Results confirmed that the polyN, N’-methylene diacrylamide (PMBA)-based cross-linking copolymer films were prepared on the 6063 Al alloy. The corrosion resistance of the PMBA-based films in the absence and presence of the EGMRA was evaluated in 3.5 wt.% NaCl solution by polarisation curves and electrochemical impedance spectroscopy as well as immersion tests. The results showed that the PMBA–EGMRA cross-linked film effectively protected the Al alloy.

摘要

使用乙二醇马来松香酸酯丙烯酸酯（EGMRA）作为交联剂，将AN，N'-亚甲基二丙烯酰胺基交联共聚物膜在6063铝合金上热聚合。分别通过傅立叶变换红外光谱和扫描电子显微镜检查共聚物膜的化学结构和形态。结果证实在6063铝合金上制备了基于聚N，N'-亚甲基二丙烯酰胺（PMBA）的交联共聚物膜。通过极化曲线和电化学阻抗谱以及浸没测试，评估了在不存在和存在EGMRA的情况下，基于PMBA的薄膜在3.5 wt。％NaCl溶液中的耐腐蚀性。结果表明，PMBA-EGMRA交联膜有效地保护了铝合金。
