Description
Technical field
The present invention relates to a kind of paper for cigarette filter tip, in particular to a kind of to have reduction ammonia of main stream smoke of cigarette content function
The cellulose paper or embossed paper of energy and their preparation method and application, belong to technical field of cigarette preparation.
Background technique
Ammonia, colourless have an intense irritation smell, can skin ambustion, eyes, respiratory apparatus mucous membrane, people's sucking is excessive, energy
Cause lung swelling, so that it is dead.It is toxicant, blood ammonia increases most obvious to cranial nerve histologic lesion.It is main in flue gas
One of harmful substance.Content of the ammonia in fresh tobacco leaves is seldom, the modulated fermentation of tobacco leaf, due to the metabolism of protein, amino acid
(reaction such as oxidation, deoxidation), content increases.Amino acid, protein, nitrate and ammonium salt in tobacco leaf etc. are in cigarette smoke
The precursor of ammonia.In cigarette, suitable ammonia cigarette more for carbohydrate and organic acid is necessary, and other
Nitrogenous compound takes part in the formation of the jealous strength of flue gas.Ammonia content is too low, will cause the decline of flue gas strength, and richness is inadequate；
But excess of ammonia can generate strong impulse, cause smoker throat to be shunk, make one to feel cough of choking, nasal cavity, tongue have pungent
Feeling unbearably.Therefore, ammonia plays an important role to control cigarette odor-absorbing.Therefore, ammonia of main stream smoke of cigarette content is reduced, is improved
Smoking safety has become great grinding of needing to solve in the target and tobacco industry development of current international consensus and pursuit
Study carefully one of project.
Currently, reduction ammonia of main stream smoke of cigarette, alternatively property unique objects object is less come the document studied.China
Patent (application number 201010288157.0) discloses a kind of cigarette processing method for reducing ammonia content, mainly using micro-
Wave changes cigarette primary processing technique to realize.Chinese patent (application number 201210041550.9) uses electron beam/x-ray irradiation
Means handle finished cigarette or tobacco leaf to realize.And what Chinese patent (application number 201210197501.4) used
It is the addition active component protoporphyrin compound in filter stick.By the blocking and absorption of solid matter can reduce simultaneously tar and
Other harmful substances matter, but applying its effect on middle low-coke tar cigarette is not that such as report is so obvious, and the reduction amplitude of tar is wanted
Amplitude is reduced higher than harmful substance, and the highly selective requirement for reducing cigarette smoke harmful components cannot be reached.And these are specially
Sharp technology is related to the problems such as technique is more complex or active component safety, at high cost, thus there are certain difficulty for application prospect.
Summary of the invention
In view of the defects existing in the prior art, the purpose of the present invention is intended to provide a kind of with selectivity reducing cigarette mainstream
Ammonia in flue gas content function, and tar content etc. is not reduced, the paper for cigarette filter tip on cigarette taste without influence.
Another object of the present invention, which is to provide, a kind of easy to operate, inexpensive prepares the paper for cigarette filter tip
Method.
Third object of the present invention is to be to provide the application of the paper for cigarette filter tip, is filtered with the standby cigarette made of paper
Stick, the property of can choose reduces the ammonia content in cigarette mainstream flue gas, and oil of focusing does not influence substantially, realizes selective reduction
Harmful substance in cigarette does not influence cigarette taste reducing the harm caused by smoker simultaneously.
In order to achieve the above technical purposes, have the function of to reduce ammonia of main stream smoke of cigarette content the present invention provides one kind
Paper for cigarette filter tip, sucrose octaacetate and/or triethyl citrate are coated on the paper for cigarette filter tip.
Technical solution of the present invention key is to use sucrose octaacetate and triethyl citrate active material is modified
Paper for cigarette filter tip is used by the conventional paper for cigarette filter tip of modified paper for cigarette filter tip replacement, has cigarette filter rod
Ammonia content in selectivity reducing cigarette main flume, this is entirely unexpected effect.
Preferred scheme, the coated weight of the sucrose octaacetate and/or triethyl citrate on paper for cigarette filter tip
To be measured by 2~10mg/ branch cigarette filter rod；More preferably for by the metering of 5~8mg/ branch cigarette filter rod.
Preferred scheme is coated with sucrose octaacetate and triethyl citrate on the paper for cigarette filter tip.It is a large amount of real
It tests and shows that sucrose octaacetate and triethyl citrate are used alone all in certain selectivity reducing cigarette main flume
The effect of ammonia content, and the two is applied in combination, there is preferably drop ammonia effect.
The mass percent of more preferably scheme, sucrose octaacetate and triethyl citrate be 55~65%:35%~
45%；The mass percent of preferred scheme, sucrose octaacetate and triethyl citrate be 60~65%:35%~
40%.The two is mixed in the ratio, can reach optimal drop ammonia effect.
Preferred scheme, paper for cigarette filter tip are cellulose paper and/or embossed paper.
The cigarette filter with reduction ammonia of main stream smoke of cigarette content function is prepared the present invention also provides a kind of
The method of stick paper, this method are that sucrose octaacetate and/or triethyl citrate are dissolved in solvent to be configured to solution, will be described
Solution is coated on the surface of paper for cigarette filter tip, it is dry to get.
Preferred scheme, the mass percent concentration of sucrose octaacetate and/or triethyl citrate is in the solution
5%~50%.
Preferred scheme, solvent are water and/or ethyl alcohol.
Preferred scheme, the drying are realized at a temperature of 60 DEG C~90 DEG C.
In technical solution of the present invention, sucrose octaacetate and triethyl citrate are coated on paper for cigarette filter tip, energy
It is reacted with the active group on cellulose paper support surface rapidly, has the characteristics that load stabilization, reaction time are short.
The present invention also provides a kind of answering with the paper for cigarette filter tip for reducing ammonia of main stream smoke of cigarette content function
With, by the paper for cigarette filter tip be applied to selectivity reducing cigarette main flume in ammonia content cigarette filter rod.
Preferred scheme, the cellulose paper for being coated with sucrose octaacetate and/or triethyl citrate are filtered as cigarette
Stick forming paper uses.
Preferred scheme is coated with the common embossing of embossed paper replacement of sucrose octaacetate and/or triethyl citrate
Paper uses.
Compared with prior art, technical solution of the present invention has the advantage that
1) sucrose octaacetate and triethyl citrate are dexterously loaded to cigarette filter rod and used by technical solution of the present invention
On paper, sucrose octaacetate and triethyl citrate can selectivity react with the ammonia in flue gas, and focusing is oily substantially without influence,
Harmful substance in selectivity reducing cigarette is realized, does not influence cigarette taste simultaneously reducing the harm caused by smoker.
2) sucrose octaacetate and triethyl citrate stability that technical solution of the present invention uses are good, pacify to human body
Entirely, compared with traditional solid adsorption material, the range of choice for dropping evil material has further been widened.
3) carrier that technical solution of the present invention uses is common cellulose paper or embossed paper, does not need other and adds
Work can be directly used as cigarette filter rod forming paper or be used as cigarette filter rod embossed paper.
4) the paper for cigarette filter tip preparation method with reduction ammonia of main stream smoke of cigarette content function of the invention is simple,
It is at low cost, meet the requirement of industrialized production.
