Filter tip additive capable of enhancing filtering capacity of cigarette filter tips as well as preparation method and applications of filter tip additive

Abstract

The invention relates to a filter tip additive capable of enhancing the filtering capacity of cigarette filter tips. The filter tip additive is prepared from the following raw materials in percentageby mass: 5-10 % of carrageenan, 5-12 % of xanthan gum, 10-20 % of guar gum, 10-19 % of sodium alginate, 20-30% of agar, and 18-50 % of activated carbon. The experiment proves that the filter tip additive is added into two-section type filter tips or three-section type filter tips with the mass being 0.1-0.3 % of that of the filter tips, so that the filtering effect for smoke can be enhanced, the total particle matter and tar contents of cigarettes can be well reduced, and thus the effect of reducing the tar and harmful components of cigarette smoke is effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a filter tip additive for increasing the filtering ability of a cigarette filter tip, a preparation method and an application thereof. Background technique [0002] In recent years, with the advancement of tobacco tar reduction and harm reduction, research on tobacco filters has also continued. As a direct and effective means of physically reducing tar and reducing harm, the filter tip filters part of the particulate matter and tar produced by tobacco combustion on the filter tip. In order to pursue a better filtering effect, the length of the filter tip is increased, and adsorption substances are added to the filter tip to further reduce coke and harm. [0003] At present, the domestic cigarette industry mainly uses a single substance such as activated carbon as a cigarette filter additive, and the effect is average. For example, patent CN2015104215702 discloses a ...

AI Technical Summary

Problems solved by technology

For example, patent CN2015104215702 discloses a preparation method and application of an embedded activated carbon filter adsorption additive, which is obtained after pretreatment of activated carbon, colloidal solution and sodium stearate, although it can effectively selectively reduce the The content of various ingredients will not bring negative effects on the migration of active ingredients, but the effect is average

In addition, the adsorption capacity of conventional additives for the filter will not change as the cigarettes are drawn shorter, and some will reduce the adsorption capacity, but as the burning of the cigarettes becomes shorter, the filtering effect of the shredded tobacco itself decreases, and at the same time The enrichment of harmful substances will cause the relative increase of harmful substances
