| 目的 制备纤维素基的包覆涂层材料，研究其原位修复与循环性能。方法 以乙基纤维素、蓖麻油和矿物油等为主要原料，采用熔融共混的方法制备得到可循环使用的包覆涂层材料。通过扫描电子显微镜(SEM)、X射线衍射仪(XRD)和红外光谱(FT-IR)研究包覆涂层材料的微观结构，通过电化学交流阻抗技术(EIS)、溶液浸泡实验和中性盐雾试验研究涂层的耐蚀性能。采用自建电磁感应设备研究包覆涂层材料的自修复性能和循环使用性能。结果 在包覆涂层材料中添加Ni粉后，使得涂层具有一定的磁响应特性。当Ni的质量分数达到15%后，有明显的团聚现象。随着Ni含量的增加，包覆涂层材料的磁性能逐渐增强。含10% Ni的包覆涂层材料在5%的HCl溶液中浸泡28天以及中性盐雾10 000 h后均无变化，同时在磁场作用下热熔循环20次，性能和结构没有太大变化。结论 添加10% Ni粉后不会对包覆涂层材料的结构和性能产生影响，同时赋予了较好的电磁感应性能。通过磁场的作用可以修复包覆涂层材料的物理损伤，同时由于包覆涂层材料具有热塑性，可以多次修复损伤以及循环使用。 |

| Recyclable coating materials were prepared, and the repairable and recyclable properties of the coating materials were studied. Ethyl cellulose, castor oil, mineral oil, etc. were used as the main raw materials to prepare the recyclable coating materials with the method of hot melt. The microstructure of the coating material was studied by Scanning electron microscope (SEM), X-ray diffractometer (XRD) and infrared spectroscopy (FT-IR). The electrochemical corrosion resistance (EIS), solution immersion test and neutral salt spray test were used to study the corrosion resistance of the coating materials. The self-made electromagnetic induction equipment was used to study the recycling performance of the coating material. The coating materials had magnetic response characteristics after adding Ni powder. When the Ni powder content reaches 15%, there was obvious agglomeration phenomenon, and the magnetic properties of the coating materials gradually increase with the increase of Ni. The coating materials containing 10% Ni powder had no change after immersion in 5% HCl solution for 28 days and neutral salt spray test for 10000 h. The coating materials properties and structure did not change after 20 cycles of hot melting under the action of an alternating magnetic field. Adding 10% Ni powder will not affect the structure and performance of the coating materials, while giving it better electromagnetic induction performance. The physical damage of the coating materials can be repaired by the action of the magnetic field. Because the coating materials is thermoplastic, it can be repaired and recycled many times. |
