Abstract

The invention relates to a filter tip addition agent for selectively reducing crotonaldehyde in smoke of a cigarette and a preparing method and application thereof. The addition agent is a composite material with polyelectrolyte nano particles loaded on the surface of a porous material. Each polyelectrolyte nano particle is a complex of chitosan hydrochloride and sodium alginate. The mass percentage composition of the polyelectrolyte nano particles in the composite material is 0.1-10.0%. According to a cigarette filter tap prepared through the addition agent, by means of the special structure of loading the nano particles on the porous material of the addition agent and functional groups of the loaded polyelectrolyte nano particles, the release amount of the crotonaldehyde in the smoke of the cigarette can be effectively and selectively reduced. In comparison with a cigarette, sold in the market, of the same specification, the cigarette tip prepared through the composite material enables the release amount of the crotonaldehyde in the smoke of the cigarette to be selectively reduced by 20-70%, fragrance ingredient loss can be avoided, and the inherent quality of the cigarette is kept.

Description

technical field [0001] The invention relates to the technical field of cigarette harm reduction, in particular to a filter additive for selectively reducing the release of crotonaldehyde in cigarette smoke, a preparation method and application thereof. Background technique [0002] Crotonaldehyde is a toxin of the cilia of the respiratory tract, which has a strong stimulating effect on the conjunctiva and upper respiratory tract mucous membrane. Long-term exposure can easily cause chronic rhinitis, nervous system dysfunction, conjunctivitis, corneal damage, etc. It is recognized as a toxic substance in cigarette smoke. One of the trace harmful ingredients. The State Tobacco Monopoly Administration also uses seven harmful components including crotonaldehyde as representatives to characterize the harmfulness of mainstream cigarette smoke. Therefore, research on reducing the release of crotonaldehyde in cigarette smoke has become an important direction in the technical field o...
