Description

A kind of remove the cigarette filter rod of heavy metal in cigarette smoke

Technical field

The present invention relates to cigarette filter rod technical field, particularly relate to a kind of Medicated cigarette filter removing heavy metal in cigarette smoke Rod.

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 remove the volume of heavy metal in cigarette smoke Cigarette filter.

The present invention is achieved by the following technical solutions:

A kind of remove the cigarette filter rod of heavy metal in cigarette smoke, be made up of the raw material of following weight portion: calcium stearate 4.3-5, acrylic resin 81-91, polyvinyl alcohol 1.2-1.5, dibenzal sorbitol 0.6-1, silica gel 5.6-7, activated carbon 2.1- 2.5, tourmaline 6.9-8, carbamide 0.6-0.9, polymine 3.3-4, deionized water are appropriate.

Described a kind of remove the cigarette filter rod of heavy metal in cigarette smoke, be made up of step in detail below:

(1) high-temperature calcination 1-2h at tourmaline and carbamide being blended in 480-550 DEG C, is ground into 50-100 mesh after being cooled to room temperature Standby；It is 40-60% that polymine deionized water is diluted to mass percent concentration, uses equi-volume impregnating by standby Tourmaline in polyethylenimine solution, activate 3-5h, temperature is 85-95 DEG C, is subsequently placed in vacuum drying oven drying；

(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 the excellent performance of tourmaline as the load perfume (or spice) adsorbent of Medicated cigarette, has life Thing effect is good, and environment-protecting asepsis is pollution-free, and utilizes polyethyleneimine-modified so that it is the substantial amounts of functional groups of area load, The supplementary set of heavy metal has extraordinary effect, the preparation method of the present invention can effectively reduce flue gas coal-tar middle oil and a huge sum of money The content of the harmful components such as genus, nontoxic, with low cost, preparation technology is simply easily achieved, before having good industrialization Scape.
