The invention also aims to provide a preparation method of the base paper of cigarette tipping paper containing tobacco elements, which comprises the following steps:

s1, crushing a tobacco raw material by adopting crushing equipment to prepare superfine tobacco powder;

s2, mixing the superfine tobacco powder prepared in the step S1 with water for extraction, and filtering to obtain an extracting solution and filter residues after the extraction is finished;

s3, concentrating the extracting solution prepared in the step S2 to prepare a concentrated solution, adding a humectant into the concentrated solution, and fully and uniformly mixing to prepare a coating liquid for later use;

s4, mixing cellulose fibers with water, pulping according to a pulping process, and preparing cellulose fiber slurry for later use after pulping is completed;

s5, mixing the filter residue obtained in the step S2 with the cellulose fiber slurry obtained in the step S4, and adding the filler and the additive in sequence to fully and uniformly mix to obtain mixed slurry;

s6, manufacturing the mixed slurry prepared in the step S5 according to a papermaking manufacturing and forming process to prepare a sheet base;

and S8, drying, rolling, calendering, slitting and rewinding the coating sample prepared in the step S7 to prepare the cigarette tipping paper product containing the tobacco elements.

Further, the ultra-fine tobacco powder in the step S1 is characterized by: the median particle size (D50) is 26.49 um-10.72 um, and the content of particle size smaller than 20um is 38.19% -81.29%.

Further, the mixing weight ratio of the superfine tobacco powder and the water in the step S2 is 1: (4.6-8), the extraction temperature is 50-80 ℃, and the extraction time is 15-70 min.

Further, in the step S4, in the pulping process, the slurry has a Shore beating degree of 60-90 SR degrees;

the absolute dry basis weight of the sheet base prepared by paper making in the step S6 is 20g/m²～30g/m²；

The oven dry basis weight of the coating sample prepared in the step S7 is 26g/m²～45g/m²。

The working principle of the invention is as follows:

crushing raw materials by using crushing equipment to prepare ultrafine powder with median diameter (D50) of 26.49-10.72 um and particle size content of 38.19-81.29% smaller than 20um, adding water for mixing, separating to obtain an extracting solution and filter residues, and extracting for pulping; adding the filter residue extracted from the raw materials and the additive into the slurry prepared by pulping to prepare mixed slurry, and then manufacturing and forming the mixed slurry by paper making to obtain the film base.

Because the raw material is ultrafine powder, if the average diameter of the plant cells is 20um (the particle size of most plant cells is between 10um and 30 um), when the particle size content of 20um is between 38.19 percent and 81.29 percent, the tobacco cells accounting for 38.19 percent to 81.29 percent are broken, the wall breaking degree of the cells is different, and the indexes of the prepared sheet base such as quantification, thickness, bulk, air permeability, tensile strength, tensile rate, moisture absorption rate and the like are different, and the indexes are important factors influencing the coating rate, smoothness, uniformity, physicochemical indexes and the like of finished products.

Tamarind gum, on the other hand, is a water-soluble xyloglucan, a water-soluble polymeric polysaccharide with glucose as the backbone and galactose and xylose as side chains. Xyloglucan is a polysaccharide present in the cell walls of higher plants, in particular the wall (main wall) fraction in which many plant cells grow. In addition, xyloglucan has a network-forming crosslinked microfibril, and therefore, the polysaccharide molecule has a strong hydrophilicity and is capable of binding many water molecules (i.e., hydration) and generating a certain viscosity, and the viscosity of the polysaccharide solution is not so high, but it is characterized by having a thickening effect in the presence of a sugar and inducing gelation. The additive is prepared by mixing one or more of tamarind polysaccharide gum, cationic starch, guar gum, chitosan and the like, and is easy to adsorb on fibers to generate retention, drainage and enhancement effects and promote molecular extension due to the similarity of the molecular main chain structure of the additive and superfine plant powder molecules in the process of preparing mixed slurry; in addition, tamarind polysaccharide gum is mixed with cationic starch, guar gum and chitosan under the accurate dosage and then is fully and uniformly mixed with the mixed slurry, and xyloglucan has the characteristics that reticular cross-linked microfibers can be fully and uniformly mixed with charged starch water-soluble substances due to branches and can easily perform mutual complexation with negatively charged fibers and superfine plant powder, so that the whole additive has uniform charge density, and the retention rate of the slurry is improved; finally, the additive containing the tamarind polysaccharide gum effectively promotes the extension of molecules in the mixed slurry, so that the molecular weight of the whole mixed slurry is moderate, excessive flocculation is avoided, and the uniformity of a film base is improved.

Based on the factors, single or diversified tobacco raw materials are subjected to superfine grinding, so that the materials used in the leaching and pulping processes are homogenized to the maximum extent, and the superfine particle powder is fully mixed with cellulose fibers and then subjected to sheet-based paper making, so that the uniformity of the sheet base is high; the fluctuation of physical indexes such as quantification, thickness, bulk, air permeability and the like is small; the paper has high physical indexes such as tensile strength, tensile rate and the like, the coated paper has fine surface, good coating consistency and small fluctuation of physical and chemical indexes, and the physical indexes such as the tensile strength, the tensile rate and the like meet the strength requirement of the paper in high-speed running. The raw paper of the cigarette tipping paper containing the tobacco elements prepared according to the process has the advantages that the natural tobacco components can reach more than 60%, the excellent physical regulation and control performance can be set and adjusted according to requirements, the appearance and color of the tobacco color are realized, no colorant is used, and the safety of the product is guaranteed.
