Abstract
The invention relates to application of polyvinyl acetate adsorption resin on cigarettes and is characterized in that the polyvinyl acetate adsorption resin is added to cigarette filters, the release amount of phenol in mainstream smoke in the cigarettes can be selectively reduced by over 25%, and the adding amount of the polyvinyl acetate adsorption resin in each filter is 10-30mg. The polyvinylacetate adsorption resin is prepared by suspension polymerization and is composed of raw materials: divinyl benzene, vinyl acetate, a pore-foaming agent, an initiating agent, water, inorganic salt and a dispersing agent. The polyvinyl acetate adsorption resin material can effectively adsorb the harmful substance phenol in the smoke, the release amount of tar is substantially unchanged or slightlyreduced, negative effects on smoking quality of the cigarettes are avoided simultaneously, and accordingly the aim of selectively reducing the release amount of phenol in the cigarette smoke is achieved.
Description
Technical field
The invention belongs to the cigarette harm reduction and add the material field, be specifically related to the application of polyvinyl acetate polymeric adsorbent in the cigarette harm reduction of phenol burst size in a kind of selectivity reducing cigarette main flume.This material is applied to cigarette filter rod, can effectively reduces phenol burst size in the main flume, the sucking quality to cigarette does not have a negative impact simultaneously.
Background technology
Phenol is one of main harmful components of cigarette mainstream flue gas, Volatile Phenols compounds in the cigarette smoke mainly produces in the cigarette burning process, " cigarette harmfulness Research on Index System " project is by the relation of research harmful components burst size and flue gas BA, find that phenol is to influence one of topmost harmful components of cigarette mainstream flue gas harmfulness, therefore, the phenol content that reduces in the cigarette smoke is significant for reducing cigarette harmfulness.
For the phenol that how to reduce in the cigarette smoke, many correlative studys have also been carried out both at home and abroad.Wang Hongwei etc. (Wang Hongwei, Fang Ding, Xu Zhiqiang, etc. Anhui agricultural sciences, 2009 (10) 4371-4372.) studied shitosan-Fe
2+Complex compound shows that to the suction-operated of harmful ingredients in flue gas it all has stronger suction-operated to flue gas moisture, phenol and HCN.Study a kind of macropore microporous hybrid starch granule in CN 101531779 patents, it has been made an addition in the filter core of cigarette filter, made binary or ternary composite filter tip, can effectively reduce tar, phenol, hydrogen cyanide and the carbon monoxide amount of sending in the flue gas.Common activated carbon fiber with reaming in the CN101015394A patent is carrier, by reaming, infusion process the aluminum nitrate of difference amount or ferric nitrate or both mixing is dispersed on the carrier, prepares different loads amount Al through roasting again

3Modified active carbon fiber, it is prepared into composite filter tip, can reduce tar, phenol, catechol, hydroquinones, resorcinol, right-metacresol and orthoresol etc. in the flue gas.Select for use dark chamber calixarene compound as adding material among the CN 101664228A, utilize molecular recognition effect and the cavity size selection effect of calixarene compound, simultaneously benzo [a] pyrene and the phenol burst size in the selectivity reducing cigarette fume.Invented a kind of novel mesoporous material for absorption cigarette mainstream flue gas tar, phenol, tobacco-specific nitrosamine etc. in the CN 101433818A patent.Mesoporous material is mesopore molecular sieve such as the SBA-15 with 3 dimension reticulated microstructure, only stone pattern, or plating is decorated with the three-dimensional netted microstructure of " liquid film " or process metal oxide such as zirconia modification, the SBA-15 meso-porous molecular sieve material of only stone pattern.CN101919589A, CN101974124A, CN101919591A, CN101961646A etc. have invented the polymeric additive of phenol type substances in a series of reduction cigarette smokes.Such additive is the phenol harmful substance in the moisture selectivity reducing cigarette fume that utilizes in the material.United States Patent (USP) (US6779529) has been announced a kind of by fibrous filter segment, selected adsorbent section and the cigarette filter that the mutual coaxial serial connection of general sorbent segment constitutes, its selected adsorbent section is that phenolic resin as matrix resin forms after primary amine and secondary amine functionalization, and this filter tip can be removed some specific compositions such as phenol etc. from flue gas.
In sum, in reducing cigarette smoke, some explorations and research have been carried out aspect the phenol burst size both at home and abroad, but these technology are relatively poor to the selective adsorption capacity of phenol in the cigarette smoke, and simultaneously material preparation process complexity, cost are higher, all are not used widely.
Summary of the invention
Purpose of the present invention just is being based on above-mentioned prior art situation and the application of polyvinyl acetate polymeric adsorbent in the cigarette harm reduction that provide, the polyvinyl acetate polymeric adsorbent makes by suspension polymerisation, this material is applied to cigarette filter rod, can effectively adsorb the harmful substance phenol in the flue gas, and releasing content of coke tar slightly reduces, sucking quality to cigarette does not have a negative impact simultaneously, thereby reaches the purpose of phenol burst size in the selectivity reducing cigarette fume.
The objective of the invention is to be achieved through the following technical solutions: the application of polyvinyl acetate polymeric adsorbent of the present invention on cigarette, be that the polyvinyl acetate polymeric adsorbent is added in the cigarette filter, the phenol burst size is more than 25% in can the selectivity reducing cigarette main flume, and its addition is every filter tip 10-30mg; The preparation method of described polyvinyl acetate polymeric adsorbent comprises following concrete steps:
