Abstract

The invention relates to an additive for a flower-scented cigarette filter rod and a preparation method of the additive, and belongs to the technical field of cigarette additives. Graphene oxide is subjected to a reduction reaction through a natural reducing agent, the obtained reduced graphene oxide reacts with a flower-scented aldehyde compound and dopamine hydrochloride, then soxhlet extractionis conducted, a graphene-based composite is obtained, and finally, the graphene-based composite prepared from various raw materials is compounded into cigarette graphene-based composite microspheres.The microspheres can selectively adsorb lauric aldehyde, myristic aldehyde, undecanal, peach aldehyde and cocoanut aldehyde from complex natural essences and flavors, the adsorption capacity is controllable, the adsorption intermolecular force of the microspheres is mainly non-covalent bond force, good heat conductivity is achieved, and in the using process, desorption can be quickly conducted; and the microspheres are prepared to form the additive for the flower-scented cigarette filter rod to be added into the filter rod to be used, the flower fragrance can be provided, the cigarette flavoris enriched, the smoking quality is improved, heat subsidence can further be prevented, and application and popularization are easy.

Description

technical field [0001] The invention belongs to the technical field of cigarette additives, and in particular relates to an additive for flower-flavored cigarette filter sticks and a preparation method thereof. Background technique [0002] Graphene is a two-dimensional carbon nanomaterial in which carbon atoms form a hexagonal honeycomb lattice with sp² hybrid orbitals. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. [0003] Tobacco additives are additives to improve the physical and chemical properties of tobacco, including flavors and fragrances, humectants, combustion enhancers, anti-mold agents and adsorbents. Wherein, the purpose of using essence and fragrance is to cover up the irritation and miscellaneous gas etc. of natural tobacco, and improve or improve ...
