Description
Technical field
The present invention relates to cigarette filter rod technical field, particularly relate to a kind of cigarette filter rod with magnetic absorption.
Background technology
The harmful substance that cigarette combustion produces, such as the N-nitrosamine in tar, benzopyrene, free radical etc., serious harm cigarette
The people's is healthy, and Chinese smoker is numerous, and Smoking is harmful to your health, must improve the safety of Medicated cigarette under existing conditions,
Inevitably cause the loss of fragrance matter, perfuming research to be carried out while reducing harmful substance, improve Medicated cigarette
Local flavor, meets consumer demand.Filter tip can with the harmful substance in effectively catching cigarette smoke, the most novel filter tip material
For reducing, cigarette smoke is coal-tar middle oil and other harmful components tool has very important significance in research.Adsorption technology subtracts at perfuming cigarette
Evil has important application, is added in filter tip after adsorbent essence, the requirement of perfuming can be met;Additionally add at filter tip
Add the adsorbent of suitable high absorption property, the CO in flue gas can be adsorbed.
In " application in perfuming cigarette harm reduction CO of the modified porous material " literary composition, author proposes to select delicate fragrance type spice two
Hydrogen actinidia lactone and geranyl acetone are applied research object, have selected aluminium silicate, montmorillonite and MCM-C41 for absorption storage perfume
Material, for presently, there are the fragrance material problem that release efficiency is the highest from these porous materials, by load glucose again
The method of high temperature cabonization is modified, and test result indicate that the adsorbent after carbonizing and modifying, and the acidic-group on its surface all increases,
Basic group all reduces, and the Desorption Activation Energy of Carbon on dihydroactinidiolide and geranyl acetone adsorbent after modification reduces,
Show that this method of modifying can effectively weaken adsorbent and show the adhesion with fragrance material, contribute to the slow release of fragrance material;
Reducing CO part, preparing the adsorbent of activated carbon supported copper the most respectively by different Cu source, testing and show to prepare
Two kinds of adsorbents all have preferably reduction CO effect.Although author is pretty good in perfuming harm reduction each side effect, but comprehensively real
Border effect and cost consideration, process is loaded down with trivial details, does not possess actual application, is unfavorable for large-scale promotion, and the present invention is from reality
Occurring, the filter stick material understanding China's tobacco business use is mainly cellulose diacetate and polypropylene fibre, diacetate fiber
Element fall Jiaozhuo is used substantially, comfortable taste, but its raw material sources are limited, and price is high, and complex manufacturing is seriously polluted, polypropylene
Fiber is cheap, and chemical stability is good, but owing to the polarity of this material is little, smooth surface, to the nicotine in flue gas and tar
Absorbability poor diacetate fiber so that it is only used in low-grade medicated cigarette, and polypropylene fibre is modified by the present invention,
Make fiber surface coarse, introduce functional group, strengthen its absorption and retain the performance of harmful ingredients in flue gas, reduce cost, economize on resources,
Invention is made to possess good Social benefit and economic benefit.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of cigarette filter rod with magnetic absorption.
The present invention is achieved by the following technical solutions:
A kind of cigarette filter rod with magnetic absorption, is made up of the raw material of following weight portion: calcium stearate 4.8-6, poly-third
Olefine resin 83-90, polyvinyl alcohol 1.2-1.5, dibenzal sorbitol 0.6-1, silica gel 5.5-6, activated carbon 3.6-4, attapulgite
5.4-6, magnetic iron oxide 0.8-1, activated alumina 2.2-2.6,0.5% pyrite extracting solution 7-8, glutaraldehyde 0.4, deionized water
In right amount.
Described a kind of cigarette filter rod with magnetic absorption, is made up of step in detail below:
(1) attapulgite is crushed to 300-400 mesh, is impregnated into 3-4h in the sodium hydroxide solution of 20%, after taking-up, uses deionization
Water washing becomes neutrality to surface, dries, and carries out mixing, stirring by the flavone extractive of modified attapulgite and 0.5%, adds
Magnetic iron oxide and activated alumina, carry out ultrasonic disperse, then drip the glutaraldehyde solution of 2-5%, reacts at 60-80 DEG C
2-3h, Magnet separates, and filters, and washing is dried;
(2) calcium stearate is added in the Oleum Terebinthinae of 15-18 times amount, is evenly stirred until dissolving, be subsequently adding the polypropylene tree of 40%
Fat mixes, and heated and stirred is completely dissolved to polypropylene, adds polyvinyl alcohol and two benzal Pyrusussuriensiss when temperature is cooled to 40-55 DEG C
Alcohol, ultrasonic disperse is uniform, is then added to pelletize in double screw extruder and makes master batch, by washing with alcohol post-drying for several times and residue
Acrylic resin blending and modifying to make modified polypropene standby;
(3) modified polypropene prepared by silica gel, activated carbon and step (2) is respectively placed in baking oven drying, drains moisture, cooling
After modified polypropene is cut into granule, the melt blending 20min in banbury by modified polypropylene particles and activated carbon granule, so
Rear addition silica gel continues 30min is blended, and cuts into the granule of uniform particle sizes after taking out cooling, be placed on capillary rheometer
In, make mixing precursor, precursor is clamped on fixture, add in hot tank at the environment of 170-180 DEG C, with the speed of 10mm/min
Uniform Tension makes fiber;
(4) load essence on product step (1) prepared, be coated in modification prepared by step (3) by binding agent compound poly-
On tacryl, after drying, conventionally make cigarette filter rod.
The invention have the advantage that the present invention pollutes for the reduction that economizes on resources, select polypropylene fibre to replace two acetic acid fine
Tie up as cigarette filter rod, use calcium stearate etc. to polypropylene modification to improve the shortcoming of polypropylene fibre so that it is surface goes out
Existing hole, crack and groove increase its specific surface area, and also use porous and poromerics silica gel, activated carbon to change polypropylene
Property so that it is become capillary polypropylene material, improve its adsorptivity further, and the means using solid phase to stretch make fiber,
Avoid the impact on polypropylene fibre absorption property of the electrostatic spinning intermediate ion liquid, improve safety, and in medicated cigarette
Harmful substance plays good crown_interception, also utilizes cross-linking reaction to make magnetic on adsorbent band, to the huge sum of money in cigarette smoke
Belong to ion and there is preferable crown_interception, and absorption property is good, carry fragrant and desorption aroma effect is good, make smoker have well
Suction impression, preparation technology of the present invention is simple, and production cost is low, can separate with externally-applied magnetic field, have after using
It is beneficial to the recovery of garbage, and with reducing harmful substance, there is good effect improving cigarette taste, be worthy to be popularized.
