摘要:

通过提高SiO₂气凝胶的亲水性来提高水性聚氨酯(WPU)涂料的防腐性能。采用脲醛对SiO₂气凝胶进行改性，并通过Fourier红外光谱(FTIR)、扫描电子显微镜(SEM)等手段表征气凝胶的结构与微观形貌；通过电化学阻抗(EIS)、附着力实验和盐雾实验等研究了涂层的防腐性能。结果表明，添加亲水改性SiO₂气凝胶的涂层的附着力和腐蚀防护性能有明显提高，其中，添加1%亲水改性的SiO₂气凝胶涂层的附着力提升36%。在3.5%NaCl溶液中浸泡70 d后涂层的低频阻抗模值超过6 × 10⁷ Ω·cm²，盐雾480 h后没有明显的鼓泡现象。

Abstract：

Waterborne polyurethane (WPU) coating, a new kind of green material due to its excellent wear resistance, flexibility, low-temperature resistance and chemical medium resistance, has been widely attached attention to the field of marine corrosion protection. In this paper, hydrophilic modification of the hydrophobic silica (SiO₂) aerogel was carried out by urea aldehyde modification. Then, the unmodified- and modified-SiO₂ aerogels as filler were added into the WPU coatings with doses 0.5%, 1% and 2%, respectively, aiming to improve the anti-corrosion properties of WPU coatings. The functional groups and microstructure of SiO₂ aerogel were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). These results proved that SiO₂ aerogel was successfully modified by urea-formaldehyde. The anti-corrosion properties of coatings with different fillers were studied by contact angle test, electrochemical impedance spectroscopy (EIS), adhesion test and salt spray test. The results showed that the adhesion of the coating was significantly improved after adding hydrophilic-modified SiO₂ aerogel. When 1% hydrophilic modified SiO₂ aerogel was added, the adhesion of the composite coating was improved by 36% correspondingly, the low-frequency impedance modulus of the composite coating increased above 6 × 10⁷ Ω·cm² after immersion in 3.5% NaCl solution for 70 d. There was no obvious bubbling phenomenon on the surface of the composite coating with 1% hydrophilic modified SiO₂ aerogel after the 480 h salt spray testing, which showed its best anti-corrosion performance. Thus, it is concluded that the hydrophilic modification of the hydrophobic SiO₂ aerogel by the urea aldehyde modification can improve the dispersibility of the hydrophobic SiO₂ aerogel in the WPU coating, the interface compatibility with the coating and the barrier and shielding effect of the SiO₂ aerogel on corrosive ions. Furthermore, the corrosion resistance of the WPU coating is improved.

Key words： silicon dioxide aerogel waterborne polyurethane hydrophilic modification anti-corrosion property long-term anticorrosion
