Description

The cigarette filter rod that a kind of absorption property is good

Technical field

The present invention relates to cigarette filter rod technical field, particularly relate to the cigarette filter rod that a kind of absorption property is good.

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 the cigarette filter rod that a kind of absorption property is good.

The present invention is achieved by the following technical solutions:

The cigarette filter rod that a kind of absorption property is good, is made up of the raw material of following weight portion: agar 5-8, acrylic acid 6-9, third Acrylamide 3.3-5, bentonite 2.8-3, N,N methylene bis acrylamide 17-21, calcium stearate 4.5-6, acrylic resin 80- 95, polyvinyl alcohol 1.6-2, dibenzal sorbitol 0.6-1, silica gel 6-8, activated carbon 4-5, deionized water are appropriate.

Described a kind of cigarette filter rod containing adsorbate, is made up of step in detail below:

(1) agar is placed in beaker, adds appropriate deionized water, be heated to 80 DEG C and make it dissolve, under the conditions of ice-water bath, Equipped with in the beaker of acrylic monomers, add appropriate 0.1mol/L sodium hydroxide solution, make acrylate moiety neutralize, then add Enter acrylamide, bentonite and N,N methylene bis acrylamide solution, stir and be placed in 85 DEG C of water-baths preheating；Then and Agar solution mixing adds Ammonium persulfate. and reacts 3-4h at 85 DEG C, filters, and is pulverized by product and is placed in 80 DEG C of baking ovens drying To constant weight；

(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 uses natural macromolecule modification sodium polyacrylate to make and has fine absorbability Composite, allow it improve the mouthfeel of medicated cigarette as carrier loaded spice, bring to smoker and well aspirate impression, in order to save About resource reduces pollution, and selection polypropylene fibre replacement diacetate fiber is as cigarette filter rod, in order to improve polypropylene fibre Shortcoming employing calcium stearates etc. are to polypropylene modification so that it is surface occurs that hole, crack and groove increase its specific surface area, and Also use porous and poromerics silica gel, activated carbon to polypropylene modification so that it is to become capillary polypropylene material, improve further Its adsorptivity, and the means using solid phase to stretch make fiber, it is to avoid electrostatic spinning intermediate ion liquid is to polypropylene fibre The impact of absorption property, improves safety, and harmful substance in medicated cigarette is played good crown_interception, prepared by the present invention Cigarette filter rod there is induction fragrance, cover impurity, remove the effect of harmful substance in Medicated cigarette, improve the quality of tobacco product, And reducing cost, preparation method subtracts three, easily operates, pollution-free, is worthy to be popularized.
