Polypropylene tip filter stick adhesive for modifying cigarettes and application thereof

The invention belongs to the technical field of assorted cigarette materials, and relates to a polypropylene tip filter stick adhesive for modifying cigarettes and an application thereof. The polypropylene tip filter stick adhesive for modifying cigarettes disclosed by the invention consists of a modifying agent and a cigarette polypropylene water-based adhesive, wherein the modifying agent comprises gluconic acid-delta-lactone, aspartame and chitin-chitosan emulsion, and the chitin-chitosan emulsion and the cigarette polypropylene water-based adhesive are home-made. Cigarettes formed by grafting cigarette polypropylene strand sticks have an absorption defect due to the chemical inertness of polypropylene fiber surfaces. The polypropylene tip filter stick adhesive for modifying cigarettes disclosed by the invention serves as an adhesive to be applied on loosened cigarette polypropylene strand surfaces in a polypropylene filter stick forming process, the modifying agent is left in the strand surfaces after drying and solidifying, and rolled polypropylene fiber tip filter sticks are grafted with the cigarettes, so that the adsorption property of tip filters can be improved, the tar content can be reduced, and the smoking taste can be improved.
