Flaky oxide aluminum as well as preparation method and application thereof
The invention discloses flaky oxide aluminum, the particle size distribution D10-D90 of the flaky oxide aluminum a is 10 [mu] m-500 [mu] m, the median thickness is 50 nm-5000 nm, and the thickness deviation is less than or equal to 20%. Taking a sulfuric acid solution as an electrochemical solution, taking an aluminum foil as a positive electrode, taking a conductive electrode as a negative electrode, and electrifying between the positive electrode and the negative electrode; cutting the aluminum foil with an aluminum oxide film on the surface to remove the edge or cut into a certain size; and carrying out dipping treatment in a copper compound solution, and carrying out ultrasonic dispersion and separation to prepare the flaky oxide aluminum. The flaky oxide aluminum is uniform and controllable in thickness; the flaky oxide aluminum has a large particle size, can be applied to functional coatings, pigments, fillers, flexibilizers, refractory materials and the like, is simple in process, simple in reaction, easy to control and low in cost, and has a wide application prospect.
本发明公开了一种片状氧化铝，所述片状氧化铝的粒径分布D10～D90为10μm～500μm，中值厚度为50nm～5000nm，厚度偏差为≤20％。以硫酸溶液为电化学溶液，以铝箔为正极，以导电电极为负极，在正极与负极之间加电；将表面包含氧化铝膜的铝箔剪切去边缘或剪切成一定尺寸；在铜化合物溶液中浸渍处理，以超声波分散，分离，制备得到片状氧化铝。本发明制备的片状氧化铝厚度均匀可控；粒径大，可应用于功能涂层、颜料、填充剂、增韧剂、耐火材料等，工艺简单，反应简单易于控制、成本低，具有广阔的应用前景。
