| 中文摘要: |
| 目的 通过特种功能纳米粒子的协同作用以及不同功能涂层的合理配套使用，获得集抗菌防霉、防腐、阻燃和耐磨等多种功能于一体，适用于涉海和航天装备综合防护的多功能纳米涂层材料。方法 以环氧树脂为底漆和中间漆的基体树脂，加入多聚磷酸盐和石墨烯复合助剂制备防腐底漆，加入石墨烯和膨胀型阻燃剂为复合阻燃助剂制备阻燃中间漆；以丙烯酸改性聚氨酯为面漆基体树脂，加入吡啶硫酮锌和纳米银抗菌复合助剂以及纳米陶瓷颗粒耐磨助剂，制备抗菌防霉耐磨聚氨酯面漆。将防腐底漆、阻燃中间漆和抗菌防霉耐磨面漆合理搭配，制备多功能一体化综合防护涂层材料。通过铅笔硬度测试、划格法附着力测试、耐冲击强度测试和耐人工老化测试评价纳米涂层的常规性能，通过盐雾测试研究防腐性能，通过燃烧实验研究阻燃性能，通过抗菌防霉实验研究抗菌防霉性能，通过摩擦实验评价其耐磨性能。结果 经测试，纳米涂层的硬度为H，附着力为0级，耐冲击强度为50 kg•cm。800 h人工老化试验后，漆膜无明显变化。800 h中性盐雾测试后，基体无腐蚀点。12 s垂直燃烧实验研究发现其平均烧焦长度仅为1 mm，滴落物的续燃时间为0 s。烟密度研究发现纳米涂层240 s的Dm平均值仅为13，抗菌、防霉实验表明该纳米涂层对大部分细菌的抑菌率高达99%，其防霉等级为0级，耐磨性能测试发现涂层的质量损失为32 mg。结论 所研制的一体化纳米涂层具有优异的防腐、阻燃、耐磨和抗菌防霉性能，可以在航天航空以及海工设施等特种设备上使用，能够起到综合防护作用。 |

| This work aims to obtain a multifunctional nano-coating material with antibacterial, antimildew, anti-corrosive and flame-retardant functions for comprehensive protection of marine and aerospace equipment depending on synergistic effect of special functional nano-particles and reasonable ancillary use of different functional coatings. Anticorrosive primer was prepared by adding zinc polyphosphate and graphene as compound agents into substrate resin taking epoxy resin as primer and intermediate paint. Antibacterial, antimildew and anti-corrosive polyurethane finish paint was prepared by adding zinc pyrithione, nano-silver antimildew compound agents and nano ceramic particle wear-resistant additive into the substrate resin taking acrylic acid-modified polyurethane as finish paint. The multi-functional integrative protective coating material was prepared by matching anti-corrosive primer, flame-retardant intermediate paint as well as antibacterial, antimildew and anti-corrosive finish paint in a reasonable manner. Conventional properties of the nano-coating were evaluated by performing pencil hardness test, cross cut adhesion test, impact strength test and artificial aging resistance test. Corrosion resistance was studied by performing salt spray test. Flame retardancy was studied by performing combustion experiment. Antibacterial and antimildew properties were investigated by performing antifungal and antibacterial experiments. Hardness of the nano-coating was up to H, adhesive force reached grade 0 and impact resistance was 50 kg•cm. After artificial aging for 800 h, the paint film changed slightly. After the neutral salt spray test, the substrate had no corrosion spot. 12 s vertical ignition test showed that the burning length was merely 1 mm and drip afterflame time was 0 s and the burn length only 1 mm. Smoke density study showed the average Dm was only 13 for 240 s. Bacteriostasis rate of the nano-coating was up to 99% and antimildew grade was grade 0. Wear resistance test showed that mass loss of the coating was 32 mg. The integrative nano-coating prepared as-developed exhibits excellent antibacterial, antimildew, anti-corrosive and flame-retardant properties, hence it plays an important role in protecting special equipment such as space aircraft and marine facilities. |
