钛纳米鳞片-有机无机杂化耐酸涂层制备及性能研究
Preparation and performance study of titanium nanoflakes/organic-inorganic hybrid acid-resistant coating
通过高能球磨法制备了钛纳米鳞片材料,并利用SEM、XPS、FT-IR和TGA对材料进行测试表征。结果表明,钛由微米级的球状变为纳米级的片状,且钛表面上接枝了有机树脂,证实了钛纳米鳞片的制备。将钛纳米鳞片作为涂层填料,通过改变填料含量实现钛纳米鳞片对涂层耐酸性腐蚀性能的强化。结果表明,钛含量为1%时涂层具有最好的耐酸性、耐腐蚀性、耐介质渗透性能;与添加未改性钛的涂层相比,添加了钛纳米鳞片的涂层的低频模值为1015 Ω·cm2,比前者高出半个数量级;涂层与基材之间的结合力没有受到影响,涂层的耐温性、耐磨性、耐盐雾性能也得到了提高。
Titanium nano scale-like flakes are prepared through high-energy ball milling method,and characterized by means of SEM,XPS,FT-IR and TGA measurements.The results show that titanium material changes from micron-sized spheres to nano-flakes,and the surface of titanium is grafted with organic resin,which confirms the preparation of titanium nanoflakes.Taking titanium nanoflakes prepared as coating fillers,the enhancement of the acid and corrosion resistance of the coating is realized through changing the content of nanoflakes filler.The results show that the coating that contains 1 % of titanium has the best resistance to the penetration of acidic corrosive medium.The low-frequency modulus value of the coating added with titanium nanoflakes is 1015 Ω·cm2,which is half an order of magnitude higher than that of the coating added with the unmodified titanium.The adhesion between the coating and the substrate is not affected,and the temperature resistance,abrasion resistance,and salt spray resistance of the coating are also improved.
