The invention discloses a continuous nanometer TiO2 surface treatment method. Nanometer TiO2 is obtained through technologies of freeze drying, silicon or aluminium coating, organosilane or long-chainfatty acid modification and the like. According to the continuous nanometer TiO2 surface treatment method, inorganic surface treatment and organic surface treatment of the nanometer TiO2 are organically combined, the continuous nanometer TiO2 surface treatment method has the characters that a technology process is short, operation is continuous and convenient, and control is easy; the nanometer TiO2 is suitable for industrial production; meanwhile, prepared nanometer TiO2 powder not only has good hydrophobicity, but also has excellent photostability, and the application fields of a product are further expanded. 本发明公开了种连续纳米TiO表面处理的方法，通过冷冻干燥、硅或铝包覆、有机硅烷或长链脂肪酸改性等工艺得到。本发明将纳米TiO的无机表面处理和有机表面处理有机的结合，具有工艺流程短、连续操作且操作方便、容易控制的特点，适宜工业化生产。同时制备出的纳米TiO粉体不仅具有很好的疏水性，而且具有优异的光稳定性，并进步扩大了产品的应用领域。
