Abstract
The present invention discloses a nitroxide free radical inhibiting filter tip with tea polyphenol and vitamin C as effective components. Tea polyphenol and vitamin C in the weight ratio of 2:1-10:1 are either compounded with ethanol and distilled water into soaking agent to soak filter tip or mixed with proper amount of adhesive into spraying agent to spray onto filter tip shred. The filter tip thus produced, when used to common cigarette, has a NO inhibiting rate of 35.2-69 %, oxygen free radical inhibiting rate of 32.3-71.9 % and NO2 inhibiting rate of 10-18 %.
Description
The present invention relates to a kind of cigarette filter and preparation method thereof, particularly relate to a kind of inhibition NO free radical cigarette filter and preparation method thereof.
Because it is saline and alkaline to contain the harmful substance and the abundant tertiary amines of tar, solid phase in the tobacco.Particularly the tertiary amines of gas phase class is saline and alkaline, in the moment of smoking and suction, generation is comprised N-nitroso thing at interior various strong carcinogens, nitrogen oxide type then is the main precursor of carcinogenicity N-nitrosamine, cause the DNA oxidation, destroy the gene base, cause dna damage etc.
For addressing these problems, in recent years, all adopt the harmful substance of removing cigarette by NACF or acetate fiber filter tip both at home and abroad in succession.But these measures can only suppress the harmful substance of tar and solid phase, and produce effects very few to the carcinogen that suppresses the gas phase class.For suppressing the murder by poisoning of cigarette smoke, people have launched research to various interpolation materials, adopt as Chinese patent 9811479.2 and add the method that is loaded with the metal oxide zeolite, reduce the NOC in the flue gas.And for example CN1145206A has disclosed a kind of low free radical and low toxicity cigarette and production method thereof, adds bluish dogbane medicinal extract and remove the solid phase free radical in pipe tobacco, is mixed and made into filter tip with Tea Polyphenols and vitamin C with finite concentration and active carbon.Also particularly point out, Tea Polyphenols, bluish dogbane and ascorbic combination are necessary, and show with detailed data, and Tea Polyphenols and ascorbic proportioning are to have best removing effect at 1: 1 o'clock.Because it is the circle of carrier that this patent application do not jump out with the active carbon, make the absorption of effective ingredient be subject to quantity and its uniformity that in filter tip, distributes of active carbon.And, being mixed and made under the aggregate measures of filter tip with the bluish dogbane tobacco shred immersion and with Tea Polyphenols and vitamin C and active carbon taking, its gas phase clearance rate also only is 26.8%.
It is that carrier is adsorbed with effective constituent with the filter tip that purpose of the present invention just provides a kind of, and can obviously improve the gas phase clearance rate, effectively suppresses the NO free radical cigarette filter.
Another object of the present invention just provides a kind of method that suppresses the NO free radical cigarette filter of producing
Task of the present invention is achieved in that with the filter tip to be carrier, the effective ingredient that absorption is made up of antioxidant Tea Polyphenols and synergist vitamin C, and Tea Polyphenols and ascorbic weight ratio are 2: 1～10: 1.By the Tea Polyphenols that extracts in the natural tea, safety non-toxic has very strong anti-oxidation function, is the strong scavenger of super qi oxide cation group and the main active oxygen of hydroxyl groups two classes and desirable nitroso thing nertralizer.Add natural synergic agent vitamin C again, can suppress NO free radical more effective, all sidedly.
Another task of the present invention is achieved in that (1). is weight ratio that 2: 1～10: 1 Tea Polyphenols and vitamin C dissolves with ethanol, adds an amount of distilled water, is mixed with the immersion liquid agent; (2). cigarette filter is placed in the immersion liquid agent soaks, soak into filter fiber fully, make effective ingredient in the immersion liquid agent be evenly distributed in the surface of filter fiber until the immersion liquid agent; (3). roll immersion liquid agent unnecessary in the filter fiber; (4). low temperature dries, and must suppress the NO free radical cigarette filter.
Another task of the present invention also can realize like this: (1). is weight ratio 2: 1～10: 1 Tea Polyphenols and vitamin C with ethanol, distilled water wiring solution-forming; (2). in the tow adhesive, mix solution and send forth on tow, make the effective ingredient in the solution be bonded on the tow equably; (3). tow is processed into inhibition NO free radical cigarette filter.
Because from as carrier, it is big to be adsorbed with the effective constituent specific area, and is evenly distributed with filter tip in the present invention;
The effective ingredient of forming by antioxidant Tea Polyphenols and synergist vitamin C, and weight ratio is set at 2: 1～10: 1, synergistic function is strong;
Make the inhibiting rate of nitric oxide, oxygen radical bring up to 35.2～69% and 32.3～71.9% respectively, to NO
2Inhibiting rate also reach 10～18%;
Effective ingredient so that the ethanol dissolving is made up of antioxidant Tea Polyphenols and synergist vitamin C is uniformly dispersed;
Be based on suppressing and removing NO free radical in the cigarette smoke with filter tip, avoided in the cigarette combustion process, the decomposition of effective ingredient produces the possibility of new harmful substance.
The present invention is described in further detail below in conjunction with embodiment.
