The invention provides a flame-retardant cellulose fiber and a preparation method thereof, and belongs to the field of flame-retardant fibers. The preparation method comprises the steps of tow pretreatment and tow after-treatment. In the step of tow pretreatment, cellulose tows are soaked in a pretreatment solution containing a silane coupling agent, and after soaking, washing and drying are conducted to obtain pretreated tows; in the step of tow after-finishing, the pre-treated tows are immersed in after-finishing liquid at 45-50 DEG C, oil bath treatment is carried out, and the flame-retardant cellulosic fibers are prepared. The flame-retardant after-finishing liquid can effectively solve the problems that after flame-retardant treatment is carried out on cellulose fibers, the physical strength of the fibers is reduced, the air permeability of the fibers is reduced, and the color vividness and color fastness of the dyed fibers are low. 本发明提供一种阻燃纤维素纤维及其制备方法，属于阻燃纤维领域。所述制备方法包括：丝束预处理、丝束后整理；所述丝束预处理，将纤维素丝束浸渍至含有硅烷
