Abstract
The invention discloses a cigarette filter additive capable of lowering phenol content in mainstream smoke and a preparation method and application of the cigarette filter additive. The cigarette filter additive is a composite formed by loading curcumin formaldehyde resin on a solid carrier. The preparation method includes dispersing the curcumin formaldehyde resin in water and adding in the carrier for soaking prior to filtering and drying to obtain the cigarette filter additive. The cigarette filter additive is good in chemical stability and safe to human bodies, the phenol content in the mainstream smoke can be lowered effectively by adding the cigarette filter additive to a cigarette filter; in addition, the preparation process and operation of the cigarette filter additive are simplified, and industrial production is satisfied.
Description
Technical field
The present invention relates to and a kind ofly can reduce additive of cigarette filter stick of phenol content in main flume and its preparation method and application, belong to cigarette producing field.
Background technology
Cigarette burning is a complicated reaction, 40 kinds are had as the phenolic compound of one of key component in flue gas, wherein topmostly comprise phenol and catechol, phenolic compound in cigarette smoke is mainly derived from the cracking of polyphenol compound in tobacco leaf (chlorogenic acid and rutin sophorin), evidence suggests that the existence of aldehydes matter can significantly improve the carcinogenic activity of polycyclic aromatic hydrocarbon, especially with phenol, adjacent, between, hydroquinones, adjacent, between, the harm of this several phenol of paracresol is large, catechol wherein in smoke condensate has auxiliary tumor promotion, part phenol has strong impulse effect to skin and respiratory mucosa.Some aldehydes matter also may affect the mouthfeel of cigarette, causes astringent taste, pungent and pleasant impression unclean etc.The number of phenolic compounds in cigarette smoke content directly affects suction quality and the harmfulness of cigarette.Therefore, adopt effective harm reduction means, at utmost reduce the loss of flavor component in cigarette smoke while optionally reducing harmful constituents in cigarette flue gas, that significantly improves cigarette sucks security, and this is current the faced important topic of tobacco business.
Reduce the research of harmful components in cigarette, main employing method comprises both at home and abroad at present: dilution method, adsorption filtration method and catalytic oxidation.Filter tip ventilation dilution is a kind of reducing tar and reducing harm technology abroad extensively adopted at present, but it is comparatively large on the impact of cigarette flavor amount, and acceptance level is also not bery high at home, in the development and application of Chinese-style cigarette, there is certain difficulty.The research of adsorption filtration method is relatively more extensive, and conventional adsorbent mainly contains active carbon, carbon molecular sieve, carbonized polymers, polymer absorbant, silica gel, activated alumina, clay and zeolite and hemoglobin etc.The composite filter of people's modified Nano materials such as Zhou Jun produces nanometer 3mg Zhongnanhai cigarette.In cigarette smoke, the selective reduced rate of total amount of harmful tobacco peculiar N-nitrosamine should be 53.5%; In flue gas, the selective reduced rate of the total amount of harmful condensed-nuclei aromatics is 67.20%, the burst size of aromatic amine harmful in the cigarette smoke of nanometer 3mg Zhongnanhai, volatile carbonyl compound, phenolic compound all has obvious reduction, wherein aromatic amine total amount selective reduced rate be 52.5%, the selective reduced rate of carbonyls is 39.2%, and the selective reduced rate of phenolic compound is 34.6%.Applying nano Fe in United States Patent (USP) 20040025895
2o
3deng harmful components such as oxynitrides, carbon monoxide, hydrogen cyanide, a-BaP, nitrosamine, phenols, acetaldehyde and benzene in reduction cigarette smoke.The people such as Li Shaoming carry out this property to Y zeolite, add in cigarette filter, can reduce aldehydes matter 45%, also can reduce other harmful substances in cigarette simultaneously.These reduce additives of harmful constituents in cigarette flue gas respectively its advantage, but security and stability is good, the research and development of falling the additive of harmful excellent effect realize industrialization, is the focus that researcher inquires into always.
Summary of the invention
The object of the invention is to be to provide a kind of chemical stability good, to human-body safety, and effectively can reduce the additive of cigarette filter stick of phenol content in cigarette mainstream flue gas.
Another object of the present invention is to provide a kind of flow process and simple to operate, and low cost prepares the method for described additive of cigarette filter stick.
3rd object of the present invention is the application process being to provide a kind of described additive of cigarette filter stick, to be added in cigarette filter rod and effective selectivity can to reduce the effect of phenol, and has that addition is little, feature to human-body safety.
The invention provides a kind of additive of cigarette filter stick that can reduce phenol content in main flume, this additive of cigarette filter stick is the composite be made up of on carrier the load of curcumin formaldehyde resin.
In preferred additive of cigarette filter stick, the load capacity of curcumin formaldehyde resin on carrier is 0.1 ~ 2% of carrier quality.
In preferred additive of cigarette filter stick, carrier is sodium alginate.
Preferred additive of cigarette filter stick is the granular materials of granule size within the scope of 40 ~ 60 orders.
In preferred additive of cigarette filter stick, curcumin formaldehyde resin is prepared by polycondensation reaction by curcumin and formaldehyde.
The preparation of curcumin formaldehyde resin (CFR) of the present invention is according to phenolic resinoid preparation method conventional in prior art, concrete operations are as follows: add curcumin, triethylamine and formaldehyde to the there-necked flask that dimethyl formamide is housed, thermal response is added 20 ~ 28 hours at 75 ~ 85 DEG C, cooling, filtration, washing, drying, obtain curcumin formaldehyde resin.Obtained curcumin formaldehyde resin has following structural formula:
Present invention also offers the method for the additive of cigarette filter stick described in preparation, the method is dispersed in water by curcumin formaldehyde resin, and after adding carrier immersion, filtration, drying, to obtain final product.
In preferred preparation method, drying is dry at 100 ~ 120 DEG C of temperature.
In preferred preparation method, drying time is 3 ~ 6 hours.
Present invention also offers the application of described additive of cigarette filter stick, additive of cigarette filter stick is added in cigarette filter rod and be applied to phenol content in selective reduction main flume.
In preferred application process, the addition of additive of cigarette filter stick in filter stick is that 20 ~ 40mg/ props up.
Compared with prior art, beneficial effect of the present invention: first curcumin formaldehyde resin (CFR) is added in cigarette filter rod for reducing phenol content in main flume as additive.Macromolecular compound CFR is prepared into loading additive by the present invention, be added in cigarette filter rod and can effectively reduce phenol content in main flume, and there is the few feature of addition, the CFR steady chemical structure in addition in filter stick additive, to human-body safety, meet the requirement that cigarette adds application.In addition, the preparation technology of CFR and compound additive is simple, and cost is low, is applicable to industrialized production.
