Description
Technical Field
The invention relates to the field of cigarette filter materials and non-woven fields, in particular to a negative ion melt-blown superfine fiber cigarette filter material and a preparation method thereof.
Background
Cigarette smoke contains particulates, commonly referred to as tar. Tar contains a large number of chemical components, 4000 to 5000 being products of incomplete combustion of tobacco. The cigarette filter is used for filtering substances harmful to human bodies, such as tar in tobacco. The present common cigarette filter tip material is acetate fiber cigarette filter tip, and the acetate fiber is produced through wet spinning, and has long production process, harmful solvent and three-waste pollution. In addition, the effect of the cellulose acetate fiber in filtering harmful carcinogenic substances (such as polycyclic aromatic hydrocarbon and aldehyde substances) in the cigarette mainstream smoke is not very ideal, and only about 40% of polycyclic aromatic hydrocarbon substances are removed.
The cigarette filter can filter smoke components to reduce the inhalation amount of tar and nicotine. However, after the cigarette is provided with the cigarette filter, the suction resistance is greatly increased, and the more toxic substances are. Such as carbon monoxide and benzopyrene, are generated by incomplete combustion of organic substances contained in tobacco during smoking, and the larger the resistance is, the less sufficient the oxygen supply is, the more incomplete the combustion is, and the more toxic substances are generated. The finer the fiber, the better the filtration performance. The three main functions of cigarette filters include direct interception, inertial compaction and diffusion precipitation, the most common being direct interception of cigarette filters. Filtration is a complex process, i.e. droplets of tar separate from the smoke and adhere to the surface of the cigarette filter material when they reach it. The thinner the fiber is, the higher the filtering efficiency of the cigarette filter, and the diameter of the acetate fiber used by the conventional filter is 7-20 μm.
Disclosure of Invention
The invention provides a negative ion melt-blown superfine fiber cigarette filter tip material and a preparation method thereof, aiming at solving the problem of low filter efficiency of cigarette filter materials in the prior art.
The technical scheme for solving the technical problems is as follows:
a negative ion melt-blown superfine fiber cigarette filter tip material, the diameter of the melt-blown superfine fiber is 1-5 μm.
Furthermore, the melt-blown superfine fiber is prepared from 94-99 parts by weight of polypropylene material and 1-6 parts by weight of nano tourmaline master batch.
Furthermore, the melt-blown superfine fiber is subjected to electret treatment.
A preparation method of a negative ion melt-blown superfine fiber cigarette filter tip material is characterized by comprising the following steps:
step S1, mixing 94-99 parts by weight of polypropylene material and 1-6 parts by weight of nano tourmaline master batch uniformly to obtain a mixture;
s2, preparing the melt-blown superfine fiber by the melt-blown device by using the mixture;
s3, cooling and bundling the melt-blown superfine fibers sprayed by the melt-blowing device by the cooling and bundling device;
and step S4, the collecting device performs electret treatment and collection on the melt-blown superfine fibers to obtain the electret superfine fiber cigarette filter tip material.
Further, the nano tourmaline master batch of the step S1 is prepared by mixing nano tourmaline materials and polypropylene materials, and the content of tourmaline is 20-40% of the mass of the nano tourmaline master batch.
Further, the cooling bundling device of the step S3 includes a cold air box and a curtain net receiving device; the step S3 specifically includes: the cold air box cools the melt-blown superfine fibers, the cooled melt-blown superfine fibers sequentially fall on a curtain receiving device which is driven along the width direction of a melt-blown die head in a melt-blown device, and the curtain receiving device bundles the melt-blown superfine fibers to obtain superfine fiber bundles.
Further, the cooling bundling device of the step S3 includes a cold air box and a first bundling device; the step S3 specifically includes: the cold air box cools the melt-blown superfine fibers sprayed by the melt-blowing device, and the first bundling device bundles the cooled melt-blown superfine fibers; and the width of the first bundling device along the width direction is not less than the width of a melt-blown die head in the melt-blown device along the width direction.
Furthermore, the melt-blown superfine fibers are cooled and converged by a cooling and bundling device, and are subjected to electret treatment by an electret treatment device.
Furthermore, the electret voltage of the electret processing device is 5-20kV, the electret interval is 20-60mm, and the electret time is 5-10 s.
The invention has the beneficial effects that: the thinner the fiber is, the higher the filtering efficiency of the cigarette filter, the diameter of acetate fiber used by the conventional filter is 7-20 μm, the conventional melt-blowing method cannot prepare fiber bundles, and only fiber non-woven fabric can be prepared. Meanwhile, the curtain net is changed from the movement perpendicular to the width direction of the fiber net of the traditional non-woven fabric preparation into the movement along the width direction of the fiber net, so that the superfine fiber bundle with the diameter of 1-5 mu m can be directly prepared. By adopting the technical scheme of the invention, the fiber with smaller diameter can be prepared, so that the filtering effect of the fiber is improved. The invention also adopts tourmaline as a manufacturing raw material, and the tourmaline can continuously release negative ions. The negative ions are called vitamins in the air, and after being inhaled into a human body, the negative ions can regulate the excitation state of nerve centers, improve the ventilation function of lungs, improve blood circulation, promote metabolism and enhance the immunity of the human body.
The anion melt-blown superfine fiber filter tip material has the advantages of small pressure drop, good air permeability, anion generation, fresh air, obvious improvement on the filtering effect of harmful substances in smoke, and capability of avoiding the environmental pollution problem in the production of acetate fibers. The cigarette filter material adopted by the invention is a thermoplastic material, has rich sources and low price, and the superfine fiber cigarette filter tip material produced by adopting the melt-blowing method has the advantages of simple production process, no pollution and high production efficiency, and the diameter of the obtained superfine fiber is between 1 and 5 mu m, and the diameter is uniformly changed little, so the filter effect is high. Meanwhile, the tourmaline mineral uniformly embedded in the superfine fibers can continuously release high-concentration negative ions, and the cigarette with the negative ion melt-blown superfine fiber cigarette filter tip is manufactured from cigarettes, is packaged into a box, is discarded until being used up, and is always under the action of the negative ions. The long-term effect results in that the content of harmful substances of tar and nicotine is reduced, and a certain fresh-keeping and mildew-proof effect is achieved, so that the irritation of the cigarette is reduced, and the taste is soft. In the smoking process of the cigarette, the smoke after combustion violently collides with high-concentration negative ions when passing through the filter tip by virtue of suction, and harmful components such as tar, nicotine and carbon monoxide in the smoke are further decomposed. Because the length of the filter tip is limited, most negative ions can not work in time and can be sucked into the mouth together with the smoke, but the decomposition effect of the negative ions on harmful ingredients in the smoke is continuously carried out in the oral cavity, the trachea and the lung lobes even in residual smoke discharged by smokers until the smoke is completely exhausted, the electret charge storage performance is good after electret treatment, and the charge retention rate can reach more than 2 years.
