| 目的 评价自主开发的聚氨酯配套体系性能。 方法 概述了海洋大气环境下钢结构涂层性能的评价方法，通过 NORSOK M-501 循环腐蚀实验来探讨聚氨酯涂料与富锌类底漆、环氧类底漆的配套性，通过 QUV 加速老化实验来对比自主开发的聚氨酯涂料与国外同类产品的抗老化性能。 结果 聚氨酯涂料与富锌类底漆的配套体系的抗腐蚀蔓延性优于与环氧类底漆的配套体系。自主开发的聚氨酯涂料体系经 4200 h 循环老化后，划线处腐蚀蔓延 5.56 mm，腐蚀蔓延小于 NORSOK M-501 标准规定的 8 mm，附着力从 12.26 MPa 衰减到 9.83 MPa，附着力衰减幅度为 19.8%，附着力衰减幅度小于 NORSOK M-501标准规定的 50%。自主开发的聚氨酯涂料在紫外光照射下老化 3000 h 后，60°光泽度从 81.5 降低到 66.5，光泽保持率为 82.94%。 结论 自主开发的聚氨酯涂料体系的耐海洋大气环境性能优良，耐循环老化和耐紫外光加速老化性能与国外同类产品相当。 |

| The work aims to evaluate the properties of the self-developed polyurethane supporting system. The evaluation methods of steel structure coating properties in marine atmosphere were summarized. The matching of acrylic polyurethane coating with zinc-rich primer and epoxy primer was investigated through the NORSOK M-501 cyclic corrosion test, and the aging resistance of the self-developed acrylic polyurethane coating was compared with that of foreign similar products through QUV accelerated aging experiment. Corrosion spreading resistance of the supporting system consisting of polyurethane coating and zinc-rich primer was better than that of the supporting system consisting of polyurethane coating and epoxy primer. For the self-developed polyurethane coating system subject to 4200 h of cyclic aging, corrosion in the marked position spread by 5.56 mm (less than 8 mm specified by NORSOK M-501 standard), adhesive force decreased from 12.26 MPa to 9.83 MPa at the attenuation amplitude of 19.8% (less than 50% specified by NORSOK M-501 standard). After aging for 3000 h under UV-irradiation, 60° glossiness of the self-developed polyurethane coating decreased from 81.5 to 66.5 while the gloss retention rate was 82.94%. The self-developed polyurethane coating system is of excellent marine atmospheric environmental resistance. Its cylic aging resistance and UV-light accelerated aging resistance are equivalent to that of foreign similar products. |
