Description
Technical field
The present invention relates to a kind of preparation methods of papery cigarette filter tip, belong to cigarette technical field.
Background technique
Still there is the smoker of substantial amounts in the world now, smoking has become social phenomenon.Worldwide can not
In the case where comprehensive smoking ban, the poisonous and harmful element in the reduction cigarette of effort has become to reduce cigarette to the harm of people
A kind of forced means.The cigarette that Institute for Medical Research encourages exploitation harmful substances from flue gases less, to be contemplated for reducing
Cigarette brings people's disease and other harm for being unfavorable for human health.Wherein a most potential approach is exactly exploitation to volume
The higher filter stick of cigarette poisonous smoke noxious substance removal efficiency.
Field mouth stick can filter out part poisonous and harmful substance in main flume, reduce harm of the main flume to human body, reduce
The risk of disease.Using different filter material of cigarette, the effect of tar reduction, safety are also different.Currently, making both at home and abroad
Filter material of cigarette has papery, acetate fiber, poly- third Kaesa fiber, activated carbon fibre, modified acetate fiber etc..
Papery filter tip stick is using wood pulp cellulose as raw material.There is following two production method, wet process embosses paper mouth rod benefit
It is obtained with body paper by resurgence, sufficient line drying, molding, finished product technique；Pure wood pulp cellulose mouth stick is by shredding, bonding, dry system
At the scraps of paper, then it is rolled into paper filter stick.Acetate fiber, that is, cellulose acetate.It is using plant cellulose and acetic acid through being esterified
React obtained staple fibre.Three glucose saccharide residues in cellulose are esterified completely by acetic acid obtains Triafol T, and three
Cellulose acetate obtains the cellulose diacetate that esterification degree is 2.0-2.7 using hydrolysis.Acetate fiber mouth stick has good
Comprehensive performance.Polypropylene fibre is synthetic fibers made of being spinned as polypropylene.In the 1960s, the states such as America and Europe begin to grind
Study carefully using polypropylene tows as cigarette filter material, the higher acetate fiber of fictitious hosts.As made of polypropylene fibre
Mouth stick comprehensive performance is substantially less than acetate fiber mouth stick, so it is generally used in Low-end Cigarettes.
Although cigarette is grown rapidly so far from appearance with filter stick, maked rapid progress, not only make cigarette more beautiful, Er Qieman
The foot requirement of reducing tar and reducing harm.But there is also following disadvantages：（1）The cigarette filter bar material of mainstream is acetate fiber at this stage
And polypropylene fibre；Modified mouth stick and composite tip stick, still using acetate fiber and polypropylene fibre as substrate.Both cigarette
Filter material, especially polypropylene fibre comprehensive performance is undesirable, is not able to satisfy and reduces tar content, reduces to human health damage
Demand, fiber filament fine crushing is sucked into lung in smoking to be done harm to huamn body；（2）Both filtering materials are difficult to biological drop
Solution, accumulates over a long period, causes damages to environment, therefore, finds the ring for being easier the mouth bar material of degradation for raising cigarette product
Guaranteed cost is significant.
Summary of the invention
The technical problems to be solved by the invention：It is acetate fiber, polypropylene fibre for cigarette filter material in the market
The disadvantages of dimension and its modified product, that there are production processes is complicated, at high cost, chemical residue, and discarding after aspirating
The problem of object is difficult to biodegrade, pollutes the environment provides a kind of preparation method of papery cigarette filter tip.
In order to solve the above technical problems, the technical solution adopted by the present invention is that：
（1）Taking cetyl trimethylammonium bromide, urea that mass fraction is added is to stir evenly in 1% acetum, adds first
Base trimethoxy silane, dimethyldimethoxysil,ne stir 30~40min, obtain reaction solution；
（2）Broken section of 5~10cm is cut into after the washing of lotus stem is air-dried, then is placed in 2~3h of firing in Muffle furnace for broken section, it is cold
But it grinds afterwards, crosses 10 meshes, obtain mould material；
（3）Modulus plate material is added in reaction solution is fitted into insulation reaction in reaction kettle after mixing, obtains presoma after cooling, will
Presoma washing, it is dry be placed on 3~5h of calcining in tube furnace, cooling porous material；
（4）Porous material, bamboo fibre, wood pulp are uniformly mixed, and manufacture paper with pulp into wet sheet with copy paper device, then be placed in baking oven
Dry 3~5h, obtains body paper；
（5）Body paper is put into embossing machine, carries out offline embossed, embossing width is 1~2mm, by the paper after embossed
It is the solid filter stick of 20~24mm that length is rolled on cigarette machine, obtains papery cigarette filter tip.
Step（1）In the reaction solution parts by weight of raw materials be 1.8~2.4 parts of cetyl trimethylammonium bromides, 10~12
Part urea, 30~40 parts of mass fractions are 1% acetum, 3~6 parts of methyltrimethoxysilane, 2~4 parts of dimethylformamide dimethyl oxygen
Base silane.
Step（2）The sintering procedure is under nitrogen atmosphere with 300~400 DEG C of 2~3h of firing.
Step（3）The mould material dosage is the 25~75% of dimethyldimethoxysil,ne quality.
Step（3）The insulation reaction temperature is 120~180 DEG C.
Step（3）The calcination process is under nitrogen atmosphere with 500~600 DEG C of 3~5h of calcining.
Step（4）The porous material, bamboo fibre, wood pulp mass ratio be 0.1：2：8.
The present invention is compared with other methods, and advantageous effects are：
（1）The present invention shows a kind of natural hierarchy construction using plant heterogeneous microstructure, has Multi hiberarchy and multi scale pipe
Shape, born of the same parents' shape or fibrous structure shape characteristic and micro-, nano-scale structure show excellent function adaptivity, with lotus
The multilevel structure of the relatively regular macropore system of stem and mutual connection be template, by methyltrimethoxysilane,
Dimethyldimethoxysil,ne poromerics, introducing carbon particle caused by in-situ carburization template strands, to carry out modulation mesoporous
The surface curvature in duct constructs micropore-hole with fine geometrical constraint ability, provides quiet needed for capture oncogenic molecules
Electric attraction strengthens the adsorption capacity to molecule and the interception effect to particle, high to the filter efficiency of tiny particles content,
When air-flow passes through fiber surface, suffered inhibition is smaller, maintains excellent gas permeability；
（2）The present invention can not only improve the physical property of paper filter stick, moreover it is possible to be effectively improved flue gas mass, eliminate xylon gas, subtract
Few irritation, make flue gas is strong, cigarette perfume it is abundant it is fine and smooth, comfortable, moisture feeling is preferable, effectively promotion cigarette smoking quality, and safety, ring
It protects, is pollution-free, degradable.
