The preparation method of the papery filter material comprises a filter material paper processing procedure, a multilayer compounding procedure, a rolling and solidifying process and a cutting and setting procedure and comprises the following specific steps of: shredding and dispersing a fiber slurry sheet material, forming a fiber mesh layer by utilizing an air-laid mode, rolling and drying to prepare a monolayer papery filter material; uniformly coating an adhesive on one face of the monolayer filter material paper, covering a second layer of filter material paper on the adhesive, rolling and compounding; then rolling and solidifying; and cutting and setting so as to obtain the papery filter material. According to the multilayer compounded papery filter material, the bulk of the papery filter material is not lost, and the tensile strength of the papery filter stick is ensured; the softness of the papery filter material is enabled to be higher than that of a product in the prior art; the rate of spreading on the surface of the filter material is low, so as to ensure the filter efficiency of the filter stick to particle matters and tar; and the preparation method is simple and convenient in process, uses natural sizing materials and meets the sanitary, safe and environment-friendly requirements.
Description
Technical field
The invention belongs to technical field of tobacco processing, further belong to cigarette filter material processing technique field, be specifically related to a kind of tensile strength height, the bulky performance is good, and the cigarette that is easy to filter stick formation is with paper filter stick filter material and preparation method thereof.
Background technology
At present, tobacco business is more and more paid close attention to the development of low-coke tar cigarette.As the important component part of cigarette, filter stick is the important technical that reduces tar content in the flue gas.Current, diacetate fiber is the main filter material of filter stick production and preparation, and its filter efficiency is higher, and outward appearance is good, cooperates the use hardness of plasticizer suitable.But along with the development of low-coke tar cigarette, its filter efficiency more and more can not satisfy the requirement of industry, and the fine filter stick of vinegar itself exists cost than problems such as height.Therefore, filter efficiency is higher, and the lower paper filter stick of cost obtains more concern gradually.
The employed papery filter material of paper filter stick generally adopts the traditional wet paper technology and gets, and when hanging down resin added, can obtain tensile strength preferably, so pliability is better, satisfies the filter stick formation requirement; But wet method prepares the papery filter material has relatively high expectations to raw material specification, and such as fibre length, neat and well spaced degree etc., preparation cost is higher simultaneously.Simple based on dry process, become the paper bulk high, pliability is better, and to advantages such as ingredient requirement are lower, dry method paper papery filter material receives publicity gradually.For example, one Chinese patent application 200510024998 " method of dry process paper filter tip and preparation thereof " discloses expanded dry method Preparation Method made of paper, and the gained filter material can satisfy the filter stick formation requirement basically.But, there is not the participation of aqueous medium in the dry method papery filter material forming process, do not have hydrogen bond action between fiber, and fiber is without processing such as making beating, so paper ubiquity tensile strength defect of insufficient.In order to remedy this defective, increase the resin added of paper usually, but cause the paper bulk to descend, hardness raises, thereby has caused the filter stick formation difficulty, and glue consumption parcel fiber easily when big, makes the filter stick filter efficiency reduce.
In sum, prior art dry method papery filter material exists tensile strength and pliability, bulk, the conflicting problem of filter efficiency.For this reason, develop a kind of deficiency that can overcome prior art, have high-tensile, and do not lose the bulky performance of paper, the cigarette that has guaranteed filter stick formation property is very necessary with the paper filter stick filter material, and has wide practical value.
Summary of the invention
First purpose of the present invention is to provide a kind of tensile strength high, and the bulky performance is good, and the cigarette that is easy to filter stick formation is used the paper filter stick filter material; Second purpose of the present invention is to provide a kind of preparation method of this kind papery filter material.
First purpose of the present invention is to realize (unless otherwise indicated, percentage of the present invention is percetage by weight) like this: papery filter material of the present invention is composited through adhesion process with the papery filter material by dry method cigarette filter rod more than 2 layers.
Second purpose of the present invention is achieved in that and comprises filter material paper conversion, MULTILAYER COMPOSITE, rolls curing and cut shaping process, specifically comprises:
A, filter material paper conversion: with the shredding of fiber pulp plate, filament dispersion, gas delivery, negative-pressure adsorption, precompressed, adopt the air lay mode to form fiber web layer, roll-in, oven dry is prepared into the single-part stationery filter material, and is subsequent use;
B, MULTILAYER COMPOSITE: with the even adhesive coating of individual layer filter material paper one side, cover second layer filter material paper on it, roll-in is compound; The compound follow-up filter material paper of same mode is until satisfying production engineering specifications;
C, roll curing: with the even adhesive coating of MULTILAYER COMPOSITE filter material paper one side, roll, carry out baking and curing then and form the filter stick section bar by technological requirement, subsequent use;
D, cut typing: the filter stick section bar is cut the cigarette that typing promptly obtains having high-tensile by technological requirement use the papery filter material.
The present invention adopts multilayer dry method filter material paper combination process, under the prerequisite of not losing papery filter material bulk, has guaranteed the tensile strength of paper filter stick; And the pliability that guarantees the papery filter material is higher than prior art products; And papery surface of filter medium resin added is low, guarantees the filter efficiency of filter stick to granule phase substance, tar; Technology of the present invention is easy, uses natural gum material, meets safe and sanitary and environmental requirement.
