Abstract
The invention discloses a method for preparing an activated carbon cigarette filter stick from tobacco straw, and belongs to the technical field of cigarette filter sticks. The method is characterized by comprising the following steps: adding water into tobacco straw, squeezing and filtering, and crushing the filtrate to obtain straw grains; preparing straw activated carbon from a part of the straw grains by using a physical activating method; extracting the rest straw grains with a mixed liquid of water and an organic solvent, removing the water and the soluble matters of the organic solvent, and removing lignin by using a sulfite method, bleaching and drying, thereby obtaining straw fiber; preparing the straw fiber into acetic acid straw fiber by using a dichloromethane homogeneous method; uniformly dispersing the straw activated carbon and the acetic acid straw fiber into a dispersing agent, drawing silk, and drying, thereby obtaining activated carbon acetic acid straw fiber; orientating strands of the activated carbon acetic acid straw fiber, loosening, gluing, coiling, cutting, and balancing the moisture, thereby obtaining the activated carbon cigarette filter stick. The invention provides the method for preparing the activated carbon cigarette filter stick with good tar reduction and harm relief effects from tobacco straw wastes.
Description
Technical field
The present invention relates to the preparation of a kind of tabacco straw containing the method for active carbon cigarette filter rod, belong to cigarette filter rod processing technique field.
Background technology
Containing multiple materials be detrimental to health such as tar, carbon monoxide and nicotines in cigarette smoke, how to remove these harmful components is the problem that people pay close attention to always, since nineteen twenty-five Hungarian Aivaz invention wadding and cellulose soft packing manufacture cigarette filter rod, tipping filter stick just becomes the main way of Tar gradually, at present, the material preparing cigarette filter rod mainly contains three kinds, acetate fiber, polypropylene fibre and paper, wherein, is most widely used with cellulose acetate filter rod.
As current most widely used cigarette filter rod material, acetate fiber is made primarily of cotton linter, wooden oar etc., but these material prices costly, and wherein, a large amount of uses of wood pulp fiber also can heavy damage ecological environment.And the stalk containing plants such as the straw of a large amount of string, soybean, corn and tobaccos often goes out of use in field, be not fully utilized, cause the serious waste of resource.
Having at present much utilizes straw to prepare the report of plant fiber filter rod, and Chinese patent CN103445295A and CN103054189A all relates to the technique preparing cigarette filter rod with raw material extraction strings such as offal, cigarette stalk, tendril, cotton fiber, wood fibres.Chinese patent CN101703314B also describes a kind of method preparing plant fiber filter rod with rice-straw fibre, wheat straw fiber, soybean stalk fiber, tabacco straw fibers mixture.But plant fiber filter rod is at reducing tar and reducing harm aspect of performance, also there is larger gap with cellulose acetate filter rod, in addition, along with Tar require increasingly strict, even cellulose acetate filter rod also cannot satisfy the demands.
Summary of the invention
The object of the invention is to: for current tobacco business problems faced in reducing tar and reducing harm, provide a kind of and make full use of the method containing active carbon cigarette filter rod that tobacco straw waste preparation meets Tar demand instantly.
Object of the present invention is achieved by the following technical programs.
Tabacco straw preparation, containing a method for active carbon cigarette filter rod, is characterized in that method step is:
(1) get 1 part of tabacco straw, add the water soaking of 2 ~ 5 parts, squeeze and filter, be crushed to 50 ~ 100 μm after filter residue and drying, make stalk particle;
(2) get part stalk particle, be made into straw-stem active charcoal with physical activation method;
(3) by preparing the remaining stalk particle of straw-stem active charcoal, filter, except anhydrating and organic solvent solubles after extracting 30 ~ 360min with water and organic solvent mixed liquor at 60 ~ 90 DEG C, collect filter residue, with the lignin in sulphite process removing filter residue, bleaching, drying, obtain stalk fibre;
(4) stalk fibre carrene homogeneous method is made acetic acid stalk fibre;
(5) get 2 ~ 10 parts of step (2) gained straw-stem active charcoals and 90 ~ 98 parts of step (4) gained acetic acid stalk fibres add in dispersant, be stirred well to and be uniformly dispersed, reel off raw silk from cocoons, dry, obtain containing active carbon acetic acid stalk fibre;
(6) carry out tow orientation, shredding, gluing to step (5) Suo Shu containing active carbon acetic acid stalk fibre, roll, cut and equilibrium water conten, obtain containing active carbon cigarette filter rod.
Described tobacco can be in flue-cured tobacco, cool cigarette, suncured tabacco, burley tobaccos, Turkish tobaccos and Nicotiniana rustica any one or multiple.
Described dispersant can be in acetone, methyl acetate, carrene and chloroform any one or multiple, the quality of dispersant is 5 ~ 10 times of straw-stem active charcoal and acetic acid stalk fibre gross mass.
The invention has the beneficial effects as follows:
1, realize the regeneration of tobacco waste resource: tabacco straw is made straw-stem active charcoal and acetic acid stalk fibre by the present invention, and then preparation is containing active carbon cigarette filter rod, realizes the object of regeneration tobacco waste resource.
2, filter stick reducing tar and reducing harm performance is improved: straw-stem active charcoal adds in acetic acid stalk fibre by the present invention, makes containing active carbon cigarette filter rod, compared with regular-size cigarette filter stick, significantly improves containing active carbon cigarette filter rod reducing tar and reducing harm performance.
3, reduce cigarette filter rod production cost: the present invention take tobacco straw waste as the raw material of preparation containing active carbon cigarette filter rod, while guarantee reducing tar and reducing harm performance, greatly reduce the production cost of cigarette filter rod.
