Zusammenfassung:	PURPOSE: An organically modified ultrafine aluminium hydroxide and a manufacturing method thereof are provided to increase organic surface treating rate by a simple process. CONSTITUTION: A manufacturing method of an organically modified ultrafine aluminium hydroxide comprises the following steps: adding silane coupling agent to the ultrafine aluminium hydroxide cake(s100), and homogeneous dispersing(s103) and drying the same(s105). The addition content of the silane coupling agent is 0.1-5 parts by weight based on 100 dry weight of the ultrafine aluminium hydroxide cake. The silane coupling agent uses one or more divalent to quadrovalent silane coupling agent which includes vinyl group or epoxy group. The ultrafine aluminium hydroxide cake has the average granularity of 0.5-5.0 micro meters and the moisture content of 30-60%.
