Abstract

The invention discloses a spout stick addictive for reducing nitrite amine peculiar in smoke gas, and the method for preparing the same. The addictive comprises granular molecular screen with granularsize being 150-500 micrometer, and noble metal or its oxide compound evenly distributed on said molecular screen with granular size being 1-50 nm, and rare-earth metal or its oxide compound. The method comprises following steps: (1) preparing granular molecular screen with size being 150-500 micrometer; (2) putting molecular screen into rare earth metal solution for 8-24 hours, washing and dryingunder 50-80 Deg. C for 3-6 hours, treating under 120-200 Deg. C for 2-5 hours; (3) putting molecular screen into noble metal solution for 8-24 hours, drying at 50-80 Deg. C for 3-6 hours, treating at120-200 Deg. C for 2-5 hours, treating at 230-300 Deg. C for 3-6 hours, and getting said spout stick addictive.

Description

technical field [0001] The invention relates to a cigarette mouthpiece additive material and a preparation method thereof, in particular to a mouthpiece additive material for reducing tobacco-specific nitrosamines (TSNAs) in cigarette smoke and a preparation method thereof. Background technique [0002] As we all know, when cigarettes are smoked, harmful substances in the smoke will cause harm to human health. At present, people have made various efforts in order to reduce this harm, such as a kind of "removal of harmful substances in cigarettes" disclosed in Chinese invention patent application publication CN 1172617A published on February 11, 1998. It intends to provide a material that can effectively remove substances harmful to health in cigarettes. The material is obtained by exchanging NaY zeolite molecular sieves with copper ions. It is fully absorbed before being inhaled into the human body or spit out into the air. However, this material has deficiencies. First, i...
