The invention discloses a production method of high-light-fastness rutile type titanium dioxide, which comprises the following steps such as preparing slurry containing rough titanium dioxide, diluting the slurry, adding phosphorus compounds, adding zirconium compounds, adding phosphorus compounds, adding alkaline aluminum compounds, curing, filtering, washing, drying, and crushing. By controlling the adding order and the additive amount of saline components of each material, the added coating agent can precipitate onto the surface of titanium dioxide particles respectively in forms of zirconium phosphate, aluminum phosphate and hydrated aluminum oxide, then through the process like curing, filtering, washing, drying and steam flow crushing, light fastness of the titanium pigment product can be increased, and the characteristics such as high brightness and high opacity can be maintained. Moreover, the dispersibility of the titanium pigment product in an aquosity system is improved, thereby facilitating slurry preparation, slurry storage and the like in use of titanium dioxide.
