The invention belongs to the technical field of tobacco products, and discloses a preparation method of a functional material rod, which comprises the following steps: mixing a plurality of functional materials to obtain a rod-making mixture; performing extrusion molding on the rod-making mixed material to form a plurality of material mixing strips, and arranging the plurality of material mixing strips in parallel in bundles to jointly form a middle material rod; carrying out fixed-length cutting on the middle material bar; providing a filter tip end rod and a fixed end rod, and coaxially arranging the filter tip end rod and the fixed end rod at an interval to form a cavity space; the cut middle material bar is placed in the cavity space, so that the filter tip end bar, the middle material bar and the fixed end bar jointly form a combined bar; and wrapping the outer side of the combined rod with forming paper to prepare a functional material rod. According to the preparation method of the functional material
