| 摘 要： | 采用硅烷偶联剂对氧化石墨烯进行改性后制备了表面功能化石墨烯，并以此功能化石墨烯制备了稳定分散的石墨烯浆料。将此浆料与溶解好的树脂液、预分散好的锌粉浆料混合，制备了石墨烯冷涂锌涂料。通过盐雾试验、接触角试验及电化学测试，确定了石墨烯在涂料体系中的最佳添加量。对石墨烯冷涂锌涂料的性能进行了全面测试，结果显示，涂层耐盐雾时间达到2500 h，是相同厚度热浸锌涂层的2倍以上。

| Abstract: | Well dispersed graphene slurry is prepared with silane-functionalized graphene oxide (f-GO). This graphene slurry is then combined with solved resin and pre-dispersed zinc slurry to prepare the cold-coating zinc paint. The best addition dosage of graphene oxide in the coating is determined by salt spray fog, contact angle test and electrochemical measurements. Properties of the cold-coating zinc paint containing f-GO are tested, and the time of resisting salt spray in the test is above 2500 h, which is about twice the time of the hot-dip galvanizing counterpart with the same thickness. |
