Description

Technical Field

[0001] The present invention relates to the technical field of tipping paper, and specifically relates to a cigarette tipping paper that prevents breakage. Background Art

[0002] Cigarette tipping paper is a special paper for wrapping the filter tip and the tobacco rod. It is mostly made of tipping paper, and its main functions are to fix the filter tip, fix the tobacco, and transmit the suction air flow.

[0003] According to different processing technologies, tipping paper is divided into two categories: printed tipping paper and coated tipping paper; printed tipping paper is printed by intaglio printing technology and is suitable for medium- and high-grade cigarettes; coated tipping paper is processed by coating technology and is commonly used in low-grade cigarettes.

[0004] Tipping paper not only plays the role of wrapping the filter tip and the tobacco, but also has a certain decorative property; and at the same time, in order to reduce the harm of smoking, holes are usually punched in the tipping paper so that external air can enter from the punched holes during suction to dilute the smoke.

[0005] However, during the production process of tipping paper, in order to meet the requirements of aesthetics, air permeability, printing adaptability, and functionality, the thickness of the finished tipping paper is relatively thin. When actual users use cigarette tipping paper, especially when a single cigarette is placed in a pocket, the cigarette may break, and the breakage usually occurs at the position of the tobacco rod; and when users buy soft-packaged cigarettes, the cigarettes may also break as the users move; this reduces the user experience.

[0006] In summary, in order to solve the technical problems proposed in this article, the present invention proposes a cigarette tipping paper that prevents breakage. Summary of the Invention

[0007] In order to make up for the deficiencies of the prior art, the present invention proposes a cigarette tipping paper that prevents breakage. The preparation method of this tipping paper includes:

[0008] Step 1: Select tipping paper, unfold the tipping paper, and then coat a gel solution on the tipping paper;

[0009] Step 2: Prepare an anti-breakage layer. The anti-breakage layer is woven by fiber filaments in a grid pattern, and the formed anti-breakage layer is placed in the gel solution for soaking;

[0010] Step 3: Take out the anti-breakage layer after soaking from the gel solution, and then perform a drying treatment on the anti-breakage layer;

[0011] Step 4: After the anti-breakage layer is dried, cut it. The width of the cut anti-breakage layer is 1-2 mm less than the width of the tipping paper;

[0012] Step 5: Lay the cut anti-fracture layer on the surface of the tipping paper. When laying, one side of the anti-fracture layer is aligned with one end of the tipping paper, and the other side of the anti-fracture layer is shorter than the tipping paper, so that there is a width of 1-2 mm of the tipping paper not covered by the anti-fracture layer;

[0013] Step 6: Curl the adhered tipping paper and the anti-fracture layer to form a complete cigarette tipping paper.

[0014] As a preferred embodiment of the present application, in Step 6, after the tipping paper and the anti-fracture layer are curled into a cylindrical cigarette tipping paper, the anti-fracture layer is located inside it.

[0015] As a preferred embodiment of the present application, in Step 2, when preparing the anti-fracture layer, the material of the anti-fracture layer is made of bamboo fiber material.

[0016] As a preferred embodiment of the present application, during the manufacturing process of the anti-fracture layer, polylactic acid is added to the bamboo fiber raw material, so that the ratio of bamboo fiber to polylactic acid is 7:3.

[0017] As a preferred embodiment of the present application, after the anti-fracture layer is laid in Step 5, tea polyphenol powder is evenly laid on it. After the tea polyphenol powder is laid, tobacco shreds are placed on the tea polyphenol powder, and then the tipping paper and the anti-fracture layer are curled. After curling, the tipping paper and the anti-fracture layer wrap the tobacco shreds.

[0018] As a preferred embodiment of the present application, before the tobacco shreds are placed on the tea polyphenol powder, bamboo fiber raw material and hydroxyapatite are mixed in the tobacco shreds. The bamboo fiber raw material accounts for 5% of the total amount of tobacco shreds, and the hydroxyapatite accounts for 3% of the total amount of tobacco shreds.

[0019] As a preferred embodiment of the present application, the gel solution in Steps 1 and 2 is starch-based nanocomposite glue.

[0020] As a preferred embodiment of the present application, the starch-based nanocomposite glue consists of 80% corn starch, 15% nano-activated carbon, and 5% plant polyphenols.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. A kind of anti - break cigarette tipping paper according to the present invention; the ratio of bamboo fiber to polylactic acid is 7:3; the main component of bamboo fiber is cellulose, and its content is between 10% and 50%. Cellulose is the main substance that composes bamboo original fiber cells, and it has relatively high strength and stiffness. Therefore, a high cellulose content makes bamboo fiber have relatively high tensile strength, so that the material of the anti - break layer is bamboo fiber, which improves the tensile strength of the anti - break layer, and then reduces the breakage risk of cigarettes; adding polylactic acid to bamboo fiber makes polylactic acid as the matrix, which can evenly bear and transfer external stress, avoiding stress concentration on bamboo fiber; and the polylactic acid matrix can restrict the movement of bamboo fiber, making the fiber stable when stressed, jointly resisting external forces, improving the overall tensile strength, and further reducing the breakage risk of cigarettes.

[0023] 2. A kind of anti - break cigarette tipping paper according to the present invention; after hydroxyapatite is mixed with tobacco, it can neutralize acidic gases, such as formaldehyde and acetaldehyde, which are harmful components produced during cigarette combustion; the hydroxyl groups of hydroxyapatite can react with acidic gases to form harmless salts, thus reducing the irritating substances in the smoke; at the same time, the porous structure of hydroxyapatite may also help to adsorb other harmful substances, such as heavy metal substances in the smoke, and then reduce the harmful substances in cigarettes.

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] Example 1:

[0030] As Figures 1 to 4 shown; a kind of anti - break cigarette tipping paper, and the preparation method of the tipping paper includes:

[0031] Step 1: Select the tipping paper, unfold the tipping paper, and then coat a gel solution on the tipping paper;

[0032] Step 2: Prepare the anti-fracture layer. The anti-fracture layer is woven in a grid pattern by fiber filaments. Place the woven anti-fracture layer in a gel solution for soaking.

[0033] Step 3: Take out the soaked anti-fracture layer from the gel solution, and then perform a drying treatment on the anti-fracture layer.

[0034] Step 4: After the anti-fracture layer is dried, cut it. The width of the cut anti-fracture layer is 1-2 mm less than the width of the tipping paper.

[0035] Step 5: Lay the cut anti-fracture layer on the surface of the tipping paper. When laying, one side of the anti-fracture layer is aligned with one end of the tipping paper, and the other side of the anti-fracture layer is shorter than the tipping paper, so that 1-2 mm of the width of the tipping paper is not covered by the anti-fracture layer.

[0036] Step 6: Curl the adhered tipping paper and anti-fracture layer to form a complete cigarette tipping paper.

[0037] In Step 6, after the tipping paper and the anti-fracture layer are curled into a cylindrical cigarette tipping paper, the anti-fracture layer is located inside it.

[0038] In Step 2, when preparing the anti-fracture layer, the material of the anti-fracture layer is made of bamboo fiber material.

[0039] During the manufacturing process of the anti-fracture layer, polylactic acid is added to the bamboo fiber raw material, so that the ratio of bamboo fiber to polylactic acid is 7:3.

[0040] The principle is as follows:

[0041] During production, after the tipping paper is unfolded, a gel solution, which is viscose, is applied to the tipping paper. Subsequently, the anti-breakage layer is prepared. Specifically, fiber filaments are woven in a grid pattern. The fiber filaments are processed by the wet spinning technology in the prior art. After the fiber filaments are processed, the processed fiber filaments are woven into a grid pattern to form the anti-breakage layer. Then, the anti-breakage layer is placed in the gel solution, and the fiber filaments are soaked with the gel solution. After soaking is completed, it is taken out and dried. The drying method can be natural air drying or drying by baking; after the anti-breakage layer is dried, it is cut. The specific cutting size is such that the width dimension of the anti-breakage layer is smaller than the width dimension of the tipping paper. For example, if the width of the unfolded tipping paper is 24.5 mm, then the width of the anti-breakage layer is 23.5 mm; after the anti-breakage layer is cut, it is laid on the tipping paper. Specifically, one end of the anti-breakage layer is aligned with the tipping paper, and there is a 1-mm gap between the other end of the anti-breakage layer and the other end of the tipping paper, so that there is a 1-mm gap on one side of the tipping paper that is not covered by the anti-breakage layer; one side of the anti-breakage layer is aligned, and the other side leaves a space. In this way, when it is curled into a cylindrical shape, the uncovered tipping paper edge can provide an additional bonding area and provide bonding conditions; in addition, the uncovered part allows the tipping paper to fit more easily when curled, reducing the generation of wrinkles or bubbles; after the anti-breakage layer is laid, tobacco is laid on the anti-breakage layer, and the tipping paper and the anti-breakage layer are curled, and the tobacco is curled between the tipping paper and the anti-breakage layer; and during this process, the anti-breakage layer is located on the inner wall of the tipping paper, so that the tobacco is in direct contact with the anti-breakage layer; after the tipping paper, the anti-breakage layer, and the tobacco are curled, the anti-breakage layer is a grid-like woven structure. When the anti-breakage layer moves on the tipping paper, due to the grid-like structure of the anti-breakage layer, the grid-like structure evenly distributes the external force to each cross node, avoiding local stress concentration, dispersing the stress, and thus reducing the probability of breakage when the cigarette is externally squeezed by a bending force or the like; and at the same time, the anti-breakage layer is located on the inner side of the tipping paper, so that the inner side of the tipping paper forms a grid-like shape. After the tobacco is located inside the tipping paper, the tobacco contacts the grid of the anti-breakage layer, increasing the friction between the tobacco and the tipping paper, and thus avoiding the problem of tobacco falling when the cigarette is placed in a cigarette case or a pocket;

[0042] In the above description, the material of the anti-fracture layer is mainly bamboo fiber material, and polylactic acid is added to the bamboo fiber raw material, so that the ratio of bamboo fiber to polylactic acid is 7:3; the main component of bamboo fiber is cellulose, and its content is between 10% and 50%. Cellulose is the main substance that constitutes bamboo fibrous cells, which has high strength and rigidity. Therefore, the high cellulose content makes the bamboo fiber have a high tensile strength, so that the material of the anti-fracture layer is bamboo fiber, which improves the tensile strength of the anti-fracture layer, thereby reducing the risk of cigarette breakage; polylactic acid is added to the bamboo fiber, so that polylactic acid as a matrix can evenly bear and transmit external stress, avoiding stress concentration on the bamboo fiber; and the polylactic acid matrix can limit the movement of the bamboo fiber, so that the fiber remains stable when subjected to force, jointly resists external forces, improves the overall tensile strength, and further reduces the risk of cigarette breakage;

[0043] When the cigarette is lit, bamboo fiber and polylactic acid will burn. The main products of bamboo fiber combustion are CO2 and H2O, and there are no persistent organic pollutants. At the same time, a small amount of lignin pyrolysis products are released, which have a slight aroma and improve the smoking experience. The main products of polylactic acid combustion are CO2 and H2O, and the microporous structure on the surface of bamboo fiber (pore size 0.1-1μm) absorbs part of the tar (adsorption rate 22%). The lactic acid vapor produced by the degradation of PLA reacts with ammonia in the flue gas to reduce the irritating smell, thereby reducing the harm of cigarette smoking to the human body.

[0044] Embodiment 2:

[0045] like Figures 1 to 4 As shown; in step five, after the anti-fracture layer is laid, tea polyphenols powder is evenly laid on it. After the tea polyphenols powder is laid, the tobacco is placed on the tea polyphenols powder, and then the tipping paper and the anti-fracture layer are curled. The curled tipping paper and the anti-fracture layer wrap the tobacco.

[0046] Here’s how it works:

[0047] In the above step five, after the anti-fracture layer is laid, tea polyphenol powder is laid on top of the anti-fracture layer. After the tea polyphenol powder is laid, tobacco is placed in the tea polyphenol powder, and then the tipping paper and the anti-fracture layer are curled. After the tea polyphenol is distributed in the cigarette, the tea polyphenol combines with benzopyrene in the cigarette through hydrogen bonds, and the adsorption rate of benzopyrene is greater than 90%, which greatly reduces the benzopyrene in the flue gas, thereby reducing the harm of cigarettes to the human body. In addition, tea polyphenol decomposes and absorbs heat during combustion, which reduces the peak combustion temperature, thereby inhibiting the formation of benzopyrene and further reducing the harm of cigarettes to the human body.

[0048] Embodiment three:

[0049] like Figures 2 to 4As shown in the figure; before placing the cut tobacco into the tea polyphenol powder, bamboo fiber raw material and hydroxyapatite are mixed in the cut tobacco. The bamboo fiber raw material accounts for 5% of the total amount of the cut tobacco, and the hydroxyapatite accounts for 3% of the total amount of the cut tobacco.

[0050] The principle is as follows:

[0051] Before placing the cut tobacco into the tea polyphenol powder, bamboo fiber raw material and hydroxyapatite are mixed in the cut tobacco. The bamboo fiber raw material accounts for 5% of the total amount of the cut tobacco, and the hydroxyapatite accounts for 3% of the total amount of the cut tobacco. Bamboo fiber itself has relatively high strength and a porous structure, which may help increase the packing density of the cut tobacco and improve the combustion uniformity. At the same time, the adsorption capacity of bamboo fiber may help reduce harmful substances in the smoke, such as tar and nicotine. In addition, the degradability of bamboo fiber may reduce the residue after the cut tobacco burns, meeting the environmental protection requirements. After mixing with the cut tobacco, hydroxyapatite can neutralize acidic gases, such as formaldehyde and acetaldehyde, which are harmful components generated during cigarette combustion. The hydroxyl groups of hydroxyapatite can react with acidic gases to form harmless salts, thus reducing the irritating substances in the smoke. At the same time, the porous structure of hydroxyapatite may also help adsorb other harmful substances, such as heavy metal substances in the smoke, thereby reducing the harmful substances in the cigarette.

[0052] Example 4:

[0053] As Figures 2 to 4 shown in the figure; the gel solution in Step 1 and Step 2 is starch-based nanocomposite glue;

[0054] The starch-based nanocomposite glue consists of 80% corn starch, 15% nano-activated carbon, and 5% plant polyphenols.

[0055] The principle is as follows:

[0056] Making the gel solution be starch-based nanocomposite glue, which uses corn starch as the main component. Corn starch has good biodegradability, but it is insufficient in terms of strength and water resistance. Therefore, the addition of nano-activated carbon will enhance its mechanical properties and provide adsorption capacity at the same time. The high specific surface area of nano-activated carbon can effectively adsorb harmful substances, such as carcinogens like benzo[a]pyrene. The addition of plant polyphenols makes the starch-based nanocomposite glue have antioxidant and antibacterial effects, further improving the health and safety of the product.

[0057] When the starch-based nanocomposite glue is coated on the tipping paper and the anti-break layer is immersed in the starch-based nanocomposite glue, where the nano-activated carbon and plant polyphenols penetrate into the anti-break layer, enhancing its bonding strength and functionality, thereby improving the use effect of the tipping paper.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
