| 目的 验证和对比在高温、高湿、高盐雾的南方海洋大气环境下的车辆腐蚀防护技术。方法 针对高温、高湿、高盐雾环境下的车辆腐蚀问题，通过试验室模拟海洋大气环境开展典型腐蚀防护技术措施的试验验证工作，进行试验数据检测和分析，评价腐蚀防护技术的腐蚀防护效果。结果 石墨烯重防腐体系样板在盐雾、老化试验3 000 h后，漆膜表面无脱落、起泡，且盐雾、老化试验前后附着力均大于8 MPa，判定该防腐体系在高湿、高盐、高温环境下的防腐年限为15~25 a。改性聚氨酯三防漆涂层电路板样板在盐雾、腐蚀、冷热冲击、霉菌试验后，表面均未产生白斑、锈迹等，通过附着力对比证明其结合强度较好。通过对疏水涂层样板盐雾试验前后的附着力进行测试对比，证明疏水涂层在高盐、高温、高湿环境下对光学镜片的结合强度较好，盐雾、霉菌试验后，涂层样板表面均未产生白斑、锈迹等。结论 通过模拟海洋大气环境，对车身金属、电气设备和光学器件的腐蚀技术进行验证，证明石墨烯重防腐体系适用于车身防腐，改性聚氨酯三防漆适用于电气设备防腐，疏水层适用于光学器件防护，后续可为典型腐蚀防护技术在车辆上的应用提供技术支撑。 |

| The work aims to validate and compare vehicle corrosion protection technologies in high-temperature, high-humidity, and high-salt-spray environments typical of southern marine atmospheres. To address vehicle corrosion issues in high-temperature, high-humidity, and high-salt-spray environments, laboratory simulations of marine atmospheric conditions were conducted to test and validate typical corrosion protection measures. Experimental data were collected and analyzed to evaluate the effectiveness of corrosion protection technologies. The graphene-based heavy-duty anti-corrosion system showed no coating peeling or blistering after 3 000 hours of salt spray and aging tests. The adhesion strength before and after the tests remained above 8 MPa, indicating that this anti-corrosion system could provide protection for approximately 15-25 years in high-humidity, high-salt, and high-temperature environments. The modified polyurethane conformal coating on circuit board samples exhibited no white spots, rust, or other defects after salt spray, corrosion, thermal shock, and mold tests. The adhesion of hydrophobic coating samples before and after the salt spray test was tested and compared, indicating that the hydrophobic coating samples had strong adhesion to optical lenses before and after salt spray tests, and had good bonding strength in high-salt, high-temperature, and high-humidity environments. No white spots or rust were observed on the coating surface after salt spray and mold tests. By simulating marine atmospheric conditions, the corrosion protection technologies for vehicle body metals, electrical equipment, and optical devices were validated. It is proved that the graphene-based heavy-duty anti-corrosion system is suitable for vehicle body protection, the modified polyurethane conformal coating is effective for electrical equipment protection, and the hydrophobic coating is ideal for optical device protection. These findings provide technical support for the application of typical corrosion protection technologies in vehicles. |
