Description
Technical field
The invention belongs to the auxiliary material production technical field of cigarette, be specifically related to one and utilize dissolution in low temperature method dissolves tobacco raw material and wood pulp cellulose, in mould, pressure filtration molding is prepared the method for cigarette mouth rod.
Background technology
In prior art, the fine mouth rod of vinegar, polypropylene mouth rod, pure cellulose mouth rod (paper mouth) and the mouth rod that contains additive are the mouth rods of four kinds of main Types in the market.The main flow in filter material market, the vinegar Xian Zuibangshi world, occupies 68% the market share; Polypropylene mouth rod occupies the market share (being all almost that China is used) of world's cigarette market 21%; The mouth rod (active carbon mouth rod is in the majority) that contains additive occupies 10% the market share; Pure cellulose mouth rod occupies the market share less than 1%.
The rejection effect excellence of the fine mouth rod of vinegar to harmful ingredients in flue gas; be widely used; but its raw material Cellulose diacetate flake (abbreviation secondary cellulose acetate sheets) is a kind of modification regeneration cellulose; it is taking high-purity bleached wood pulp as raw material; make acetylizing agent with aceticanhydride; acetic acid is made solvent; under catalyst action; wood pulp cellulose is carried out to acetylation; through pretreatment, acetify, hydrolysis, precipitating, washing, extruding, dry; make cellulose obtain modification, become and dissolve in acetone and other organic solvent, the Cellulose diacetate flake of tool spinnability.Acetate fiber technology is monopolized by external Ji Jia major company, and the raw material of producing Cellulose diacetate flake is the rare timber that grows in highland, North America, and production range is limited, and the cycle is long, has greatly restricted the production scale of vinegar fibre mouth rod.The organic solvent environmental pollution of using in production is more serious, also easily residues in mouth rod and hazard cigarette consumer's health.
Polypropylene mouth rod is to the rejection effect of harmful ingredients in flue gas not as the fine mouth rod of vinegar, and production process also affects environmental protection, has obvious chemicals taste and affect suction taste in cigarette smoke.
Papery mouth rod, owing to being rich in polar group in natural fiber chemical constitution, easily absorbs water, adsorbs various polarity chemical substances; Fiber surface structure is rough, holds back oiliness and solid particulate matter not worse than the fine mouth of vinegar rod, but has obvious paper taste and apply less.
The quick method of the dissolving cellulos of the dissolution in low temperature Fa Shi Zhang Lina academician of Wuhan University invention, this method adopts the quick dissolving cellulos of 7wt%NaOH/12wt% aqueous solution of urea of-12 DEG C, this novel solvent system has adopted most economical, prevailing industrial chemicals, not only production technology is simple, with short production cycle, inexpensive, and chemical raw material used easily reclaims, can be recycled, be therefore known as free of contamination characteristics among new solvents of cellulose and " green " spinning technique.The dissolution in low temperature method of Zhang Lina academician's invention is mainly used in wet spinning technology, prepares filament, film, chromatographic column filler, composite etc., is applied to the preparation of mouth bar material, and in the one-shot forming technique of material, also has no report but have no it.
Summary of the invention
For the above-mentioned deficiency of prior art, the technical problem to be solved in the present invention is to provide the manufacture method of a kind of one-shot forming cigarette mouth rod, and it does not have spinning process, directly one-shot forming, and technique is simple, with short production cycle, is a kind of brand-new mouth rod preparation method.
Technical scheme of the present invention is: the manufacture method of mouth rod for a kind of one-shot forming cigarette, contain injection molding apparatus, and described method is carried out according to the following steps successively:
(1) tobacco material and wood pulp cellulose are dissolved in the 7wt%NaOH/12wt% aqueous solution of urea of-12 DEG C and obtain colloidal solution, tobacco material and wood pulp cellulose: the ratio of 7wt%NaOH/12wt% aqueous solution of urea is 1:3-23;
(2) internal diameter that step (1) gained tobacco material and wood pulp cellulose colloidal solution is injected into injection molding apparatus is 7.6mm, is highly in the mould of cylindrical, hollow of 50～120mm, is as the criterion to fill; Described mould bottom and impermeable plastic foil are adjacent, and under described plastic foil, going back place mat has 300 object chemical fibre material filter clothes;
(3) whole shaped device is warming up to 30 DEG C, keep, after 30 minutes, removing the impermeable plastic membranous layer of mould lower end, air compressor shower nozzle is aimed to mould upper port, with the colloidal substance of the last moulding in the air mass flow press filtration mold cavity of 1～5ml/min, continue 5～10min;
(4) in mould, inject water purification, consumption is 10～30ml, with the speed press filtration of 10～100ml/min; Repeat above operation 1-2 time of this step;
(5) with injection machine to the shitosan/1wt% aqueous acetic acid 10～30ml that injects 1wt% in mould, with the speed press filtration of 10～100ml/min;
(6) the molded material in mold cavity is taken out, dry, divide the length that is cut to needs, be one-shot forming cigarette mouth rod.
Described tobacco material and wood pulp cellulose refer to a kind of in tobacco leaf, offal, wood pulp cellulose or the mixture among them.Described wood pulp cellulose refers to commercially available bleached wood pulp.
Advantage of the present invention: this method does not have spinning process, directly one-shot forming, technique is simple, with short production cycle, is a kind of new mouth rod preparation method; The industrial chemicals cheap and simple of application, easily reclaims, and can be recycled.
