The invention provides a preparation method of a cigarette filter tip rod with blending material controlled-release cool sense essence. The preparation method comprises the specific steps that a supermolecular material and aqueous ethanol with the mass fraction of 0%-95% are mixed to be uniform according to the weight ratio of 1:0.5-1:30 to obtain a supermolecular solution; a temperature-sensitive macromolecular material and aqueous ethanol with the mass fraction of 0%-95% are mixed to be uniform according to the weight ratio of 1:0.5-1:30 to obtain a temperature-sensitive macromolecular solution; the supermolecular material solution and the temperature-sensitive macromolecular solution are mixed according to the weight ratio of 1:(0.1-10) and then subjected to ultrasonic treatment, a cool sense essence solution mixed with aqueous ethanol is added into the mixed solution, stirring is performed, the mixed solution is subjected to ultrasonic treatment and then applied to shreds in the filter tip rod forming process, and the cigarette filter tip rod is obtained after filter tip rod forming. According to the cigarette filter tip rod, essence is slowly and continuously released, therefore, the cigarette smoking comfort is improved, and harm of a cigarette to human health is reduced.
