摘要:
本文主要研究纳米二氧化硅浓缩浆和纳米氧化锌浓缩浆对海洋环氧涂料和聚氨酯涂料性能的影响。通过盐雾试验、氙灯老化试验、人工海洋加速老化试验研究海洋腐蚀环境中纳米复合涂料的耐腐蚀性和抗老化性。通过三步法制备高稳定分散的纳米氧化物浓缩浆，并利用纳米二氧化硅浓缩浆和纳米氧化锌浓缩浆改性海洋船舶环氧底漆和聚氨漆酯船壳漆，制备海洋纳米复合涂料。利用TEM透射电镜、FTIR红外光谱、XPS光电子能谱、光泽度仪、表面接触角测试仪和粘结强度测试仪等研究海洋船舶漆的耐腐蚀性、抗老化性及表面防污性能。纳米二氧化硅浓缩浆的红外光谱分析和粘度测试及纳米氧化锌浓缩浆的透射电镜观察表明高分子分散剂的长碳链位阻效应保证了纳米粒子的均匀稳定分散。不含有纳米二氧化硅浓缩浆的环氧漆粘结强度是4.4 MPa，而含有1.0%纳米二氧化硅浓缩浆的环氧漆粘结强度增加到5.6 MPa。通过氙灯老化试验测试涂层的光泽度变化，纳米聚氨漆酯漆的光泽度高于不含纳米氧化锌的普通聚氨漆酯漆光泽度。聚氨漆酯漆在海洋循环加速老化试验后C/O值减少20.1%，而含有1.2 %纳米氧化锌浓缩浆的纳米复合聚氨漆酯漆老化后C/O值仅减少10.7%,抗氧化性提高。通过对海洋加速循环老化试验中纳米聚氨漆酯漆的测试分析表明1.2%纳米氧化锌浓缩浆提高了海洋船舶聚氨酯面漆的抗老化性和表面接触角。纳米浓缩浆增强纳米复合涂料在海洋重腐蚀环境中耐腐蚀、抗老化等性能。
Abstract:
The aim of this paper is to investigate the effect of SiO2 nano-concentrate and ZnO nano-concentrate on properties of epoxy and polyurethane marine coating. The corrosion-inhibiting and anti-aging properties of composite nano-coatings used in marine environment were investigated by the salt spray test, xenon lamp aging test, ocean accelerated cycle aging test. The stable well-dispersed nano-concentrates were prepared by three-step method, and epoxy and polyurethane marine nano-coatings were modified by SiO2 nano-concentrate and ZnO nano-concentrate. The work has investigated corrosion resistance, weathering resistance and antifouling property of marine nano-coating by use of transmission electron microscopy (TEM), fourier transform infrared spectrometer (FTIR), X-ray photoelectron spectroscopy (XPS), gloss meter and measuring instrument of surface contact angle. The FTIR analysis and viscosity measurement of SiO2 nano-concentrates and TEM observation of ZnO nano-concentrates demonstrate that the well-dispersed state of nanoparticles can be attributed to the strong steric effect of long carbon chains of polymer dispersing agent. The bonding strength of epoxy nano-coating with 1.0% SiO2 nano-concentrate increases from 4.4 MPa of epoxy coating without nano-concentrate to 5.6 MPa. The analytic results of salt spray test demonstrate that 1.0% SiO2 nano-concentrates improve the resistance of epoxy nano-coating to salt spray. The gloss measurement in the xenon lamp aging test demonstrates that gloss of polyurethane nano-coating is higher than that of polyurethane coating without nanoparticles. The C/O ratio of polyurethane coat ing without nano-concentrate after accelerated cycle aging test dramatically decreases 20.1% while the C/O ratio of polyurethane nano-coating with 1.2 % ZnO nano-concentrate after aging test only decreases 10.7%.The measurements of gloss and surface contact angle during ocean accelerated cycle aging test indicate that 1.2% ZnO nano-concentrations greatly enhance the anti-aging and surface contact angle of polyurethane coating. In conclusion, the nano-concentrates can improve corrosion resistance and weathering resistance of nano-coatings in marine heavy corrosion environment.
