Description

Technical Field

[0001] The invention relates to the technical field of cigarette tipping paper, in particular to an anti-seepage tipping paper and a processing technology thereof. Background Art

[0002] Cigarette tipping paper, also known as tipping paper, is a special paper used to wrap cigarette filters. It may also have ink and layers printed on the outside of the cigarette tipping paper, which also has a decorative effect on the appearance of the cigarette.

[0003] In addition, the printing ink and coating of tipping paper must be non-toxic and meet food hygiene standards because they are in direct contact with the smoker's lips; with the development of technology, tipping paper also has the function of reducing tar content. When used in conjunction with high-transparency plug-in paper, it helps reduce the harm of smoking to health.

[0004] However, when using existing cigarettes, especially when smoking, people will hold the cigarette in their mouths for a long time. At this time, saliva in the mouth will pass through the cigarette filter and enter the acetate fiber material inside it. The acetate fiber itself is hygroscopic, which increases the probability of moisture in the saliva entering the interior, making the cigarette filter and acetate fiber wet. When the cigarette filter is wet, the wet filter will affect the passage of smoke, resulting in a worse taste when smoking. The smoke may become bitter or bland, which in turn leads to poor smoking effect for the user.

[0005] In summary, in order to solve the technical problem raised in this article, the present invention proposes an anti-seepage tipping paper and a processing technology thereof. Summary of the Invention

[0022] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0023] Embodiment one:

[0024] As shown in the drawings; a processing technology of the anti-seepage tipping paper, the processing technology comprises the following steps: Figs. 1-3

[0025] Step one, select a tipping paper, then coat a layer of polyacrylate solution on the outside of the tipping paper, after the polyacrylate solution is coated, dry it by air drying;

[0026] Step two, coat glue on the end of the tipping paper which is not coated with polyacrylate solution, then select a sheet-shaped water bag, fill the water bag with oxidase, then adhere the water bag to the glue;

[0027] Step three, after the water bag is laid, lay acetate fiber on the water bag, then roll the tipping paper and the water bag, after rolling is completed, the acetate fiber is wrapped by the tipping paper and the water bag, after wrapping, a complete cigarette filter is formed, connect the formed cigarette filter with the tobacco rod of the cigarette to form a complete cigarette;

[0028] The width of the water bag is 1mm smaller than that of the unfolded tipping paper, when laying the sheet-shaped water bag, align one side of the water bag with the unfolded tipping paper, then lay it, after laying is completed, the area of the tipping paper with a width of 1mm is not covered by the water bag;

[0029] In the above step two, before laying the water bag, coat glue on one end of the water bag, the glue is selected to be water-sensitive glue;

[0030] The oxidase filled in the water bag in step two is selected to be lipase.

[0031] The principle is as follows:

[0032] ​When the tipping paper is processed, a layer of polyacrylate solution is coated on the outer side of the tipping paper, and the polyacrylate solution is air-dried, then glue is coated on one end of the tipping paper which is not coated with the polyacrylate solution, then a sheet-shaped water bag is laid on the glue, and before the water bag is laid on the glue, an oxidase is injected into the water bag, where the oxidase is selected as lipase; the material of the water bag is selected as the same as the material of the microcapsule in the prior art; and the width of the sheet-shaped water bag is less than 1mm of the expanded tipping paper, so that after the water bag is laid on the tipping paper, the tipping paper has a 1mm exposed space for laying the acetate fiber on the water bag, then the water bag and the tipping paper are rolled, after rolling, the two ends of the tipping paper need to be bonded, and the 1mm exposed space of the tipping paper makes it easy to bond the tipping paper, and the tipping paper cannot be bonded due to the water bag; and when the tipping paper and the water bag are bonded, since glue is coated on one end of the water bag in advance, the two ends of the water bag are bonded together by the glue after rolling, and then the exposed area of the tipping paper is bonded above the other end of the tipping paper; when the user uses the tipping paper of the present application, since a layer of polyacrylate solution is coated on the outer side of the tipping paper, and after the polyacrylate solution is air-dried, a thin film is formed on the outer side of the tipping paper, and the molecular structure of the polyacrylate film contains hydrophobic groups such as carbon-hydrogen segments, which have a repelling effect on water molecules, making it difficult for water to spread and penetrate on the surface of the film, thereby reducing the probability of moisture on the filter tip of the cigarette when the user smokes the cigarette even if the user holds the cigarette for a long time; at the same time, since the tipping paper and the water bag are rolled, the tipping paper and the water bag wrap the internal acetate fiber at the same time, and the water bag itself has a waterproof effect, so that the water bag effectively wraps the outer circle of the acetate fiber, preventing the internal acetate fiber filter layer from being wet;

[0033] When the user finishes smoking the cigarette, the user can manually squeeze and pinch the filter tip of the cigarette, at this time the tipping paper and the water bag are squeezed, when the water bag is squeezed, the water bag is damaged, and the water source and the lipase in the water bag flow out, after the water mixed with the lipase flows out, it will wet the tipping paper, then the water and the lipase will react with the thin film of the polyacrylate solution on the outer side of the tipping paper, the lipase first contacts the surface of the thin film formed by the polyacrylate solution, cuts off the high molecular chain on the surface by hydrolysis, and generates small molecular weight compounds, these small molecular products are more easily naturally degraded than the complete polyacrylate mixture; and as the polyacrylate surface layer is continuously degraded, the lipase gradually penetrates into the film, continues to catalyze the hydrolysis of the internal ester bond, thereby realizing the overall degradation of the film;

[0034] And because the water bag is coated with glue at one end, when the water bag and tipping paper are curled, the water bag is connected end to end, and when the water bag is broken, because the glue at the end of the water bag is water-sensitive glue, such as low-molecular-weight PVA glue, when the water in the water bag flows out, it will contact the glue at the end of the water bag, causing the glue at the end of the water bag to dissolve and lose its stickiness, thus separating the two ends of the water bag, and at the same time, the moisture will soak the tipping paper, making it easy to unfold, and when the tipping paper and water bag are unfolded, the inside of the filter is exposed to the air, increasing the contact area between the inside of the filter and the air, increasing the degradation rate of the internal acetate.

[0035] Example Two:

[0036] As shown in Figs. 1-3 Step two, the glue coated on the tipping paper is water-sensitive glue loaded with a photocatalyst;

[0037] The photocatalyst used in the glue coated on the tipping paper is titanium dioxide nanoparticles, specifically, the titanium dioxide nanoparticles are slowly added to the glue before the glue is coated on the tipping paper.

[0038] The principle is as follows:

[0039] Based on the above-mentioned example one, the glue coated on the tipping paper in step two is water-sensitive glue loaded with titanium dioxide nanoparticles, that is, titanium dioxide nanoparticles are uniformly dispersed in water-sensitive glue (such as low-molecular-weight PVA glue), and then coated on one end of the tipping paper that is not coated with polyacrylate, used to paste the sheet-shaped water bag filled with lipase; When the tipping paper is not pinched, the tipping paper is in a dry state, the water-sensitive glue is tightly combined with the fibers of the tipping paper by intermolecular hydrogen bonds, ensuring that the water bag is stably attached during the processing and storage of cigarettes, avoiding displacement or falling off; After the user finishes using the cigarette, the user pinches the tipping paper, causing the water in the water bag to flow out, which will soak the glue between the water bag and the tipping paper, causing the glue to dissolve after coming into contact with water, and at the same time, the titanium dioxide nanoparticles in the glue will separate from the glue along with the water, which will contact the film formed by the polyacrylate solution on the surface of the tipping paper, and when the user discards the filter, under the sunlight on a sunny day, the titanium dioxide particles will promote the production of hydroxyl radicals and superoxide radicals, which will accelerate the oxidation and rupture of the ester group on the surface of the polyacrylate film on the outside of the tipping paper, thus accelerating the degradation rate of the polyacrylate;

[0040] In the first embodiment, since the glue bonded to the tipping paper is water-sensitive, when the water in the water bag contacts the bonding points at the two ends of the tipping paper, the adhesion between the two ends of the tipping paper is lost. At the same time, the adhesion between the two ends of the water bag is lost, causing the tipping paper and the water bag to unfold. After the tipping paper unfolds, the contact area between the acetate fiber inside the tipping paper and the air is larger. In addition, after the tipping paper unfolds, the tipping paper, the water bag, and the acetate fiber are in an unfolded state, resulting in a larger contact area with light, thereby accelerating the degradation of the polyacrylate by the titanium dioxide particles.

[0041] At the same time, after the water bag ruptures, the water in the water bag will enter the acetate fiber, and the water and lipase mixture in the water bag will simultaneously enter the acetate fiber filter layer. On the one hand, water will increase the humidity of the acetate fiber, thereby increasing the dissolution of the acetate fiber. On the other hand, after the lipase enters the interior of the acetate fiber, it can catalyze the hydrolysis reaction of ester bonds. Acetate fiber contains a large number of ester bonds. Lipase catalyzes the hydrolysis of these ester bonds and degrades high-molecular-weight acetate fiber into low-molecular-weight acetic acid and cellulose, thereby further accelerating the degradation of acetate fiber.

[0042] Example 3:

[0043] like Figs. 1-3 As shown; in step three, before the acetate fiber is laid on the water bag, graphene oxide is added to the acetate fiber so that the graphene oxide is mixed with the acetate fiber.

[0044] Here’s how it works:

[0045] In the above embodiment 1, before laying the acetate fiber, the graphene oxide and the acetate fiber staple fibers are mixed, and the mixing method can be mechanical uniform mixing. The mixed acetate fiber is then laid on the surface of the water bag and then crimped into shape;

[0046] On the one hand, when graphene oxide is evenly mixed with cellulose acetate, the graphene oxide has a high specific surface area, which increases the filtering effect of graphene oxide on harmful substances in smoke and reduces the harmfulness of cigarette smoke to the human body;

[0047] On the other hand, when graphene oxide is mixed with lipase, graphene oxide has rich surface functional groups, such as hydroxyl, carboxyl and epoxy groups. These functional groups can interact with lipase and enhance the catalytic activity of lipase. At the same time, graphene oxide has a large specific surface area and excellent adsorption properties, which can adsorb more lipase molecules; increase the contact area between the enzyme and acetate fiber, thereby improving the degradation efficiency of acetate fiber.

[0048] Example 4:

[0049] like Figs. 1-3The permeation-preventing tipping paper is prepared by the permeation-preventing tipping paper processing process, and the tipping paper comprises that micro-holes are arranged at the joint of the tipping paper and the tobacco rod.

[0050] The principle is as follows:

[0051] By means of laser drilling at the joint of the tipping paper and the tobacco rod (i.e. the interface area of the filter and the cigarette), micro-holes with a diameter of 5-10 μm are arranged in an array, so that when a user smokes the cigarette, the micro-hole design can make external air enter the smoke through the micro-holes and mix with the smoke, thereby reducing the content of harmful substances in the smoke and enhancing the smoothness of smoking.

[0052] The basic principle, main features and advantages of the present application are shown and described above; it should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principle of the present application, and various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
