Abstract

Zn–Al layered double hydroxides (Zn–Al LDHs) were prepared in situ on the surface of zirconium phosphate (ZrP) nanosheets in order to improve the lubricating capabilities of LDHs in waterborne epoxy (WEP). Subsequently, ZrP-LDHs (ZL) were functionally modified with tannic acid (TA) and cerium ions (Ce(Ⅲ)) to prepare ZrP-LDH-PTA-Ce(Ⅲ) (TCZL) nanohybrids. Subsequently, the WEP coating was combined with TCZL to create a dual-purpose coating exhibiting wear resistance and anti-corrosion properties. The tribological test results demonstrated that the WEP coating containing TCZL (TCZL/WEP) exhibited a 75.27 % lower wear rate than the blank WEP coating. Furthermore, the Electrochemical impedance spectroscopy (EIS) showed that the impedance modulus at 0.01 Hz (|Z|_0.01 Hz) of the TCZL/WEP coating was roughly 2 orders of magnitude higher than that of the blank WEP coating after 35 days of corrosion. In summary, TCZL/WEP exhibits excellent wear resistance and anti-corrosion performance. This high-performance functional coating exhibits excellent anti-corrosion and excellent wear resistance, with numerous application opportunities across multiple industries.

在磷酸锆上原位生长层状双氢氧化物以增强水性环氧涂料的耐腐蚀和耐磨性

在磷酸锆（ZrP）纳米片表面原位制备了锌铝层状双氢氧化物（Zn-Al LDHs），以提高其在水性环氧树脂（WEP）中的润滑性能。随后，用单宁酸（TA）和铈离子（Ce（Ⅲ））对zrp - ldh （ZL）进行功能修饰，制备ZrP-LDH-PTA-Ce（Ⅲ）（TCZL）纳米杂化体。随后，WEP涂层与TCZL涂层结合，形成具有耐磨和防腐性能的双重用途涂层。摩擦学试验结果表明，含TCZL的WEP涂层（TCZL/WEP）的磨损率比空白WEP涂层降低了75.27%。电化学阻抗谱（EIS）表明，腐蚀35 d后，TCZL/WEP涂层在0.01 Hz （|Z|0.01 Hz）处的阻抗模量比空白WEP涂层高约2个数量级。综上所述，TCZL/WEP具有优异的耐磨性和防腐性能。这种高性能功能性涂料具有优异的抗腐蚀和耐磨性，在多个行业中具有广泛的应用机会。
