Abstract
The invention discloses a kind of formaldehydeless overlapping glue and preparation method with burnt sweet fragrance; the present invention connects crystalline cellulose as sorbing material using acetylated modification nanometer; being handled by acetylated modification improves dispersiveness of the nanocrystal cellulose in overlapping glue; so as to obtain a large amount of activity hydroxies and higher specific surface area; activity hydroxy with the intermolecular generation of free formaldehyde by chemically reacting to generate stable covalent key connection; most free formaldehyde molecule is fixed, so as to significantly reduce the free formaldehyde release of overlapping glue；The nanocrystal hydrophobic cellulose performance Jing Guo acetylated modification is improved simultaneously; the overlap joint that obtained overlapping glue is applied to cigarette paper not only has burnt sweet fragrance; improve the suction taste of cigarette; poisonous fume generation can also be reduced; and can while quality of tobacco shreds is kept to keep cigarette circularity; adhesive property is good, and water resistance is strong, and can avoid seam broken that cigarette machine occurs when taking mouthful, run phenomena such as bar, pleat and wrinkle.
Description
Technical field
The present invention relates to cigarette field of adhesive technology, and in particular to a kind of formaldehydeless overlapping glue with burnt sweet fragrance
And preparation method.
Background technology
As production of cigarettes one of most important adhesive, overlapping glue is mainly used in the bonding at cigarette longitudinal interface.
To make cigarette whip stitch smooth, avoid gas leakage, run the generation of phenomena such as bar, overlapping glue also needs to have on the premise of adhesive property is good
Standby glue uniformity, without caking, bubble-free, free from admixture and the rate of drying characteristic such as soon.At present, domestic cigarette industry it is more with
VAE（VAE）Emulsion uses as overlapping glue.
In cigarette glue, overlapping glue directly participates in burning, because overlapping glue discharges miscellaneous gas of plastic cement etc. in combustion
Penetrating odor, so as to have impact on the suction taste of cigarette, thus need to perfuming cigarette to improve the suction taste of cigarette.Generally, cigarette
Perfuming is concentrated mainly on pipe tobacco, stem, thin slice and filter tip etc., and the research of overlapping glue perfuming is limited only to add essence.With
The continuous lifting that present people are required cigarette, in particular with the increase of numerous Ms's amount of smoking, " outer odor type " is rolled up
The demand of cigarette is incremented by therewith, and the research report that " outer odor type " cigarette is prepared by the use of overlapping glue as flavor carrier is very few.
In currently available technology, document《The preparation of burnt sweet fragrance overlapping glue and its application in cigarette》With WBA/C70
Cigarette is discharged of the coke by the use of overlapping glue as material of main part by preferred essence, polyvinyl alcohol volume and sodium carboxymethylcellulose volume, preparation
Sweet fragrance type cigarette overlapping glue, it is achieved thereby that application of the overlapping glue characteristic perfuming technology in fragrant obvious type cigarette is smelt, for volume
The research and development of cigarette perfuming auxiliary material product provide new thinking.But existing overlapping glue in process of production in the prevalence of
The problem of content of formaldehyde severe overweight, substantial amounts of free formaldehyde is can release in solidification and ageing process, environment can be caused
Pollute and threaten the health of people.The Main Means taken at present include improvement synthesis technique and addition sorbing material.So
And the method for adjusting preparation technology can all cause the decline of its bonding strength while free formaldehyde release is reduced, so
Sorbing material is added to reduce the extensive concern that the research of content of formaldehyde gradually causes researcher.
The content of the invention
It is existing to overcome it is an object of the invention to provide a kind of formaldehydeless overlapping glue and preparation method with burnt sweet fragrance
There is the deficiency of technology.
The object of the present invention is achieved like this：
A kind of formaldehydeless overlapping glue with burnt sweet fragrance, it is characterised in that be used as material of main part, acetylation using cigarette by the use of overlapping glue

Described essence is homemade JT-08.
Described cigarette is with the overlapping glue that overlapping glue is that the commercially available trade mark is WBA/C70.
The addition that described acetylated modification nanometer connects crystalline cellulose is：1.5-2wt.%, its preparation method include following
Step：
（1）Nanocrystal cellulose is put into glacial acetic acid and stirred and evenly mixed, 10-15min is ultrasonically treated under ice-water bath protection, adds
Enter acetic anhydride and catalyst in 50-60 DEG C of stirring reaction 1-2 hours at room temperature；
（2）After reaction terminates, by step（1）Material is poured into and white flock precipitate is separated out in ethanol, and precipitation is stayed in centrifugation, is first used
Ethanol washs 3 times, then with deionized water centrifuge washing 3 times, obtains acetic anhydride-modified nanocrystal aqueous cellulosic suspension；
（3）Above-mentioned water slurry is freeze-dried to constant weight, acetylated modification nanometer is obtained and connects crystalline cellulose.
Described 1g nanocrystal celluloses correspond to 25mL glacial acetic acid, 0.1mL catalyst and 7mL acetic anhydrides, wherein described
Catalyst be perchloric acid, at least one of the concentrated sulfuric acid.
The preparation method of described a kind of formaldehydeless overlapping glue with burnt sweet fragrance, it is characterised in that including following step
Suddenly：
（1）Cigarette is connect crystalline cellulose and be added in rustless steel container with overlapping glue, acetylated modification nanometer, warming-in-water to 70-
80 DEG C, stirring is opened, mixing speed is 120-200 revs/min, and stirring 1-2 hours are well mixed；
（2）Keeping temperature is constant, continuously adds essence, polyvinyl alcohol and sodium carboxymethylcellulose and stirs and evenly mixs, constant temperature emulsification 1-2
Hour；
（3）PH to 4.5-6.0 finally is adjusted with sodium carbonate liquor, is cooled to room temperature, filtering and discharging.
The present invention has following beneficial effect：The present invention receives using existing cigarette by the use of overlapping glue as material of main part, acetylated modification
It is sorbing material that rice, which connects crystalline cellulose, and being handled by acetylated modification improves nanocrystal cellulose disperses in overlapping glue
Property, so as to obtain a large amount of activity hydroxies and higher specific surface area, activity hydroxy by with free formaldehyde intermolecularization
Learn reaction and generate stable covalent key connection, most free formaldehyde molecule is fixed, mouth is taken so as to significantly reduce
The free formaldehyde release of glue；The nanocrystal hydrophobic cellulose performance Jing Guo acetylated modification is improved simultaneously, obtained
The overlap joint that overlapping glue is applied to cigarette paper not only has burnt sweet fragrance, improves the suction taste of cigarette, can also reduce poisonous fume generation,
