Description
Technical Field
The invention relates to a paper filter material, in particular to a paper filter material of paper-making fiber, and also relates to a preparation method and application thereof, belonging to the field of new material development of cigarette filter sticks.
Background
The cigarette filter is a main cigarette auxiliary material in the tobacco industry, and the selection of the material of the cigarette filter has obvious influence on the smoking quality and tar reduction of the cigarette. Compared with the acetate fiber filter stick commonly used at present, the paper filter stick has obvious advantages in tar reduction, cost and environmental protection, but the cigarette with the paper filter stick has the defects of dry smoke, large irritation, obvious wood gas, bitter aftertaste and the like during cigarette smoking, so that the paper filter stick is difficult to be commonly applied to cigarettes. At present, the research reports about the modification of paper filter sticks at home and abroad still use pure wood pulp fiber paper or bamboo pulp fiber paper as a carrier, and the defects of the paper filter sticks are not essentially improved. Therefore, the search and development of novel plant fiber materials have become one of new means for improving the quality of paper filter sticks.
In the prior art, studies have been made to blend a certain proportion of bagasse fibers in wood pulp fibers, and the paper filter stick blended with the bagasse fibers can increase the sweetness of smoke when a cigarette is smoked, but the bagasse fibers belong to short fibers, so that the tensile strength of a paper base prepared by using the paper filter stick alone is not enough, and the paper breaking phenomenon can occur in the processing of the paper filter stick, thereby affecting the processing stability.
Paper mulberry bark, which is called paper mulberry bark, milk bark, millet bark, paper mulberry and the like, is a perennial deciduous tree. The paper mulberry has high cellulose and pectin content and low lignin content. The average length of the paper mulberry fiber is between that of flax and kenaf, obvious transverse striations are formed on the fiber wall, the cell cavity is obvious, and the two ends of the fiber are sharp and are branched. The paper-making wrapper has long been used as a paper-making raw material, and the bast fiber of the paper-making wrapper is slender, high in strength, white and flexible, is a high-quality paper-making fiber raw material, and is also the earliest raw material applied to paper making in China. The paper has ivory color, smooth writing, strong ink absorption, fresh scent, difficult color change, difficult damage, long preservation time and other characteristics. At present, the paper-making fiber is mainly used for producing high-grade paper, special paper, artificial cotton and the like with higher requirements on fiber quality.
The paper-making fiber is a long fiber, and the paper-making fiber is tried to be used for cigarette paper filter materials in consideration of the material characteristics, and related documents and reports do not appear at present.
Disclosure of Invention
In order to solve the problems, the invention provides a preparation method of a paper filter material of paper-making fibers and application of the paper filter material of paper-making fibers obtained by the method in cigarette paper filter sticks or composite filter sticks.
The paper-based paper filter material is prepared by properly cutting paper-based fibers, pulping and making paper into a paper filter material paper base, and coating and drying the paper base by using the extracting solutions of dark plum and olive fruits, so that the defect of poor taste absorption of a common paper filter stick is overcome, and the performance and the effect are better.
The purpose of the invention is realized by the following technical scheme:
a preparation method of a paper filter material of paper fibers with paper structure comprises the following steps:
(1) preparing a paper base: the method comprises the steps of (1) carrying out hydraulic pulping and defibering on a commercially available paper mulberry bark pulp board, then carrying out pulp grinding on the paper mulberry bark pulp board by using a KRK high-concentration disc grinder, wherein the pulp concentration is 10-15% by mass, the disc grinding gap is 0.1-0.2mm, then carrying out pulp grinding on a PFI pulp grinder, the pulp concentration is 5-8% by mass, controlling the beating degree to be 30-40 DEG SR, adding a conventional auxiliary agent into the pulp, then carrying out paper making forming on a paper forming machine, and drying the paper for later use;
(2) preparation of coating liquid: mixing and crushing dark plum and olive fruit according to the mass ratio of 3:7-7:3, and then carrying out hot reflux extraction with water to obtain an extracting solution, wherein the material-liquid ratio during extraction is 1:25-1:40, the extraction temperature is 65-75 ℃, and the extraction time is 1.5-3 h; filtering the extract, concentrating under reduced pressure to obtain concentrated solution, adding 95% ethanol with the same volume as the concentrated solution for alcohol precipitation, centrifuging, and collecting supernatant as coating liquid;
(3) preparing a paper filter material: and (3) coating the coating liquid prepared in the step (2) on the paper base prepared in the step (1) and then drying, wherein the adding amount of the coating liquid on the paper base is controlled to be 0.3% -1.2%.
KRK mainly lies in the cutting action to the fibre, and PFI is more obvious to the devillicate brooming effect of fibre, because the paper-structure skin fibre is longer than traditional wood pulp or bamboo pulp fibre, in order to obtain the better paper base of quality, adopts the method of carrying out PFI defibrination after KRK defibrination earlier.
The paper filter material of the paper-made wrapper fiber has faint scent when no extracting solution is added, reduces wood miscellaneous gas and the like, but has other defects in sensory quality, and as the paper filter stick for cigarettes, a certain amount of feed liquid needs to be added to improve the suction quality of the paper filter stick, so that the comprehensive sensory quality of the paper filter stick is relatively balanced. According to the invention, the smoked plum and olive fruit extracting solution is coated on the paper substrate of the paper wrapper and used for the filter stick, so that the irritation of smoke can be reduced, the sweet and fragrant note is increased, and the comfort of the oral cavity and the aftertaste sweet feeling are improved.
Further, in the step (1), the basis weight of the paper sheet is controlled to be 37 +/-1 g/m2, and the thickness is controlled to be 0.12 +/-0.02 mm.
Further, after filtration, the mixture was concentrated under reduced pressure to 1/4 in terms of volume.
Further, in the step (1), after defibering, refining is carried out for 2 times by a KRK high-consistency disc mill.
The invention relates to a paper filter material made of paper fiber with paper structure skin prepared by the preparation method.
The invention relates to application of the paper filter material of paper-structured fiber in cigarette paper filter sticks or composite filter sticks.
Compared with the prior art, the invention has the advantages that:
(1) due to the long fiber characteristic of the paper-making filter stick, the paper-making filter stick paper base is made by properly cutting and grinding the paper-making fibers, the tensile strength of the paper base is superior to that of wood pulp fibers and bamboo pulp fiber paper bases, the stability of the paper filter stick during rolling is improved, and a novel plant fiber material is provided for the paper filter stick.
(2) The smoked plum and olive fruit extracts for the paper base of the paper filter material of the paper-making fiber are developed, and the problems of dry smoke, large stimulation and reduced texture of the traditional paper filter stick are solved.
(3) The paper filter material with the paper-made wrapper fiber can bring fresh and sweet aroma when the cigarette filter stick is used for smoking cigarettes, reduces the paper flavor of the cigarette with the paper filter stick during smoking, reduces the irritation, improves the aroma quality to some extent, and makes the mouth sweet.
