Abstract
The invention discloses an additive for reducing ammonia release quantity in cigarette smoke and a preparation method thereof. Alkaline earth metal chlorides are dispersedly loaded on meso-porous silicon; the load is less than 40% of total weight; the aperture of meso-porous silicon is 2-50nm; the specific surface area is not smaller than 300m<2>/g; and the particle size is 40-80 meshes. The method comprises the steps of weighing alkaline earth metal compound to dissolve into a proper amount of deionized water; agitating to form uniform solution; adding the meso-porous silicon to evenly agitate, standing for 12 hours at room temperature, putting into an oven to dry, and cooling to room temperature to obtain the additive. Compared with the prior art, the preparation method is simple in process, low in cost, and significant in ammonia-reducing effect, and can achieve industrial application; and a filter rod with the additive added therein disclosed by the invention is applied to the cigarette. From the result of experiments, the release quantity of ammonia in the cigarette smoke can be effectively reduced; the gas-phase ammonia is greatly reduced by the functional meso-porous silicon material; and particle-phase ammonia is also reduced to a different extent.
Description
Technical field
The present invention relates to a kind of NH in the selectivity reducing cigarette main flume that has
3The adsorbent of burst size.
Background technology
Along with the progress of society, people improve constantly the attention rate of self health, and China further strengthens Harm reduction techniques and falls burnt dynamics as the signatories to a treaty of " Framework Convention on Tobacco Control ", is related to the survival and development of China's tobacco business.Show according to international tobacco research organization statistics, by 2011, the composition of having identified in cigarette smoke surpassed kind more than 5000, and wherein 99.4% composition is harmless.2009, the cigarette smoke harmfulness index research by Zhengzhou tobacco research institute takes the lead and carried out Chinese-style cigarette filtered out 7 kinds of representative compositions as cigarette Evaluation of Harmfulness index in 29 kinds of harmful components of cigarette mainstream flue gas, and ammonia is wherein one.
Ammonia not only affects the sucking quality of cigarette, also can stimulate vision and the respiratory system of human body, and long-term suction meeting causes more serious harm to human body.Therefore, the research that reduces ammonia burst size in cigarette smoke to improve the cigarette quality, to improve the smoking property of cigarette security significant.
So far, launch around its assay method and formation mechanism about the research overwhelming majority of ammonia in flue gas.The research that both at home and abroad ammonia in cigarette smoke is reduced technology seldom, is mainly to realize falling ammonia by the means that reduce tar, selectively falls the ammonia DeGrain.
Summary of the invention
Given this, the object of the invention is to provide the functionalization adsorbent of ammonia burst size in a kind of selectivity reducing cigarette main flume.
For solving above technical problem, technical scheme provided by the invention is, on the one hand, ammonia burst size additive in a kind of reduction cigarette smoke is provided, spread loads alkaline earth metal chloride on mesoporous silicon, the mass percent that load accounts for total amount is not more than 40%, and the mesoporous silicon aperture is 2-50nm, and specific area is not less than 300m
2/ g, granularity is the 40-80 order.
Preferably, to account for the mass percent of total amount be 25% in described load.
Preferably, described alkaline earth metal compound is CaCl
