Description

Technical Field

[0001] The invention relates to the technical field of cigarette tipping paper, in particular to an aromatic flame-retardant tipping paper. Background Art

[0002] With the development of society and the improvement of consumers' health awareness, the tobacco industry has continuously increased its performance requirements for tipping paper. In the early days, tipping paper mainly served the basic function of connecting cigarettes to filters, and only needed to have a certain degree of flexibility and strength to ensure that it would not be damaged during cigarette production and consumer use. However, today, consumers are not only concerned about the taste of cigarettes, but also increasingly value the safety and added experience during smoking. This has prompted the need for tipping paper to have more functionalities, such as flame retardancy and pleasant aroma, to enhance the overall quality and market competitiveness of cigarettes. Secondly, the flame retardant effect of the cigarette itself also needs to be given enough attention. For example, when a cigarette is burning, if a person plays with a mobile phone or is not paying attention to the cigarette while smoking, the burning cigarette may burn the fingers. Also, during the process of smoking a cigarette, if the cigarette is discarded, it will continue to burn without the action of external force and will not extinguish itself.

[0003] In summary, in order to solve the technical problem raised herein, the present invention proposes an aromatic flame-retardant tipping paper. Summary of the Invention

[0004] The present invention provides an aromatic flame-retardant plugging paper, the preparation of which includes the following steps: Step 1: Take a piece of tipping paper that wraps tobacco, and apply glue on one end of the tipping paper. The glue coating area occupies one-fifth of the tipping paper. Step 2: Select an aerogel composite material and apply glue on the surface of the aerogel composite material; Step 3: stick the glue-coated aerogel composite material to one end of the tipping paper coated with glue; Step 4: curling the tipping paper. After curling, the tipping paper includes the aerogel composite material at one end, so that the tipping paper forms a tobacco rod with one end blocked. Step 5: Fill the rolled tobacco rod with tobacco to form a complete tobacco rod.

[0005] As a preferred solution in the present application, in step 2, after the aerogel composite material is selected, the aerogel composite material is formed into a sheet, and then the aerogel composite material is laid on the area where the tipping paper is coated with glue.

[0006] As a preferred solution in the present application, glue is applied on the upward side of the aerogel composite material; and then the fiber reinforcement material is laid thereon.

[0007] As a preferred solution in the present application, the fiber reinforcement material is an activated carbon fiber material, and when the aerogel composite material is curled, the activated carbon fiber material is layered between the aerogel composite materials.

[0008] As a preferred solution in the present application, metal oxide is added to the raw materials of the aerogel composite material before the aerogel composite material is prepared into a sheet shape.

[0009] As a preferred solution in the present application, antimony trioxide is used as the metal oxide.

[0010] As a preferred solution in the present application, in step one, after coating the glue coating area, plant extracts are added to the glue coating area.

[0011] As a preferred solution in the present application, the plant extract is eugenol particles.

[0012] As a preferred solution in the present application, before coating the eugenol particles on the tipping paper, nano-silica material is added to the clove powder particles, and then the aerogel composite material is coated on the surface of the eugenol and silica material.

[0013] The beneficial effects of the present invention are as follows: When the tobacco rod is burned, the aerogel composite material has high air permeability and will not affect the passage of smoke; and when the cigarette burns to the position of the aerogel composite material; the aerogel composite material can be used as the key flame retardant layer of the wrapping paper due to its excellent thermal insulation performance; such as the common silica aerogel composite material, its nanoporous structure gives it extremely low thermal conductivity; when the cigarette burns to the position of the aerogel composite material, heat is transferred to the aerogel composite material, and the aerogel layer can effectively buffer the heat conduction; the gas in the large number of pores inside it expands due to heat and absorbs heat, reducing the heat transfer toward the filter tip, thereby preventing the remaining cigarette from overheating and burning, thereby reducing fire hazards and reducing the problem of people getting burned if they are not careful.

[0015] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0016] Example 1:

[0017] Figures 1 to 4 As shown; An aromatic flame retardant plugging paper, the preparation of the plugging paper comprises the following steps; Step 1: Take a piece of tipping paper that wraps tobacco, and apply glue on one end of the tipping paper. The glue coating area occupies one-fifth of the tipping paper. Step 2: Select an aerogel composite material and apply glue on the surface of the aerogel composite material; Step 3: stick the glue-coated aerogel composite material to one end of the tipping paper coated with glue; Step 4: curling the tipping paper. After curling, the tipping paper includes the aerogel composite material at one end, so that the tipping paper forms a tobacco rod with one end blocked. Step 5: Filling the rolled tobacco rod with tobacco to form a complete tobacco rod; In step 2, after the aerogel composite material is selected, the aerogel composite material is formed into a sheet, and then the aerogel composite material is laid on the area where the tipping paper is coated with glue.

[0018] Here’s how it works: During the production of the flame-retardant tipping paper, glue is applied to one end of the tipping paper, and then the aerogel composite material is laid on the end of the tipping paper coated with glue. During the production of the aerogel composite material, it is produced into a sheet, and the size of the sheet of aerogel composite material is the same as the size of the glue-coated area; After the aerogel composite material is laid, the staff curls the aerogel composite material into a cylindrical shape, then curls the tipping paper and wraps the tipping paper around the outer ring of the rolled aerogel composite material. The glue on the tipping paper is bonded to the outer ring of the aerogel composite material, so that the aerogel composite material and the tipping paper form a barrel-shaped structure with one end blocked. Then, tobacco is filled into the tipping paper to form a complete tobacco rod; the tobacco rod is connected to the cigarette filter to form a complete cigarette; When the cigarette tipping paper formed above is in use and the tobacco rod burns, the aerogel composite material has high air permeability and will not affect the passage of smoke; and when the cigarette burns to the position of the aerogel composite material; the aerogel composite material can be used as a key flame retardant layer of the tipping paper due to its excellent thermal insulation performance; such as the common silica aerogel composite material, its nanoporous structure gives it extremely low thermal conductivity; when the cigarette burns to the position of the aerogel composite material, heat is transferred to the aerogel composite material, and the aerogel layer can effectively buffer the heat conduction; the gas in the large number of pores inside it expands due to heat and absorbs heat, reducing the heat transfer to the direction of the filter, thereby preventing the remaining cigarette from overheating and burning, thereby reducing the fire hazard and reducing the problem of people getting burned by carelessness; The nanoporous structure of aerogel composite materials is not only heat-insulating and flame-retardant, but also has a certain adsorption effect on tiny particles and some harmful gases produced by cigarette burning; for example, when smoke passes through the filter area containing aerogel composite materials, the aerogel pores can intercept tiny particles such as tar, reducing their entry into the human body. At the same time, its adsorption effect on some harmful gas molecules helps to purify the smoke.

[0019] Example 2:

[0020] Figures 2 to 4 As shown; glue is applied to the upward side of the aerogel composite material; and then fiber reinforcement is laid on top of it; The fiber reinforcement material is an activated carbon fiber material, and when the aerogel composite material is curled, the activated carbon fiber material is layered between the aerogel composite materials.

[0021] Here’s how it works: In the first embodiment, glue is applied to the upward side of the aerogel composite material, and then a fiber reinforcement material is laid on top. The fiber reinforcement material uses an activated carbon fiber material. When the sheet-shaped aerogel composite material in the first embodiment is curled, the sheet-shaped aerogel material will wrap the activated carbon fiber between each layer of aerogel material to form a layer. When the smoke passes through the aerogel composite material and the activated carbon fiber, the aerogel composite material and the activated carbon fiber will jointly filter the smoke from the burning cigarette. The aerogel composite material first intercepts most of the larger-sized tiny particles through its pore structure, reducing the filtration burden of the activated carbon fiber; while the activated carbon fiber, with its strong adsorption capacity, adsorbs the smaller particles that penetrate the pores of the aerogel composite material, forming a "first interception, then adsorption" collaborative filtration mode; this synergistic effect greatly improves the overall filtration efficiency of tiny particles. For harmful gases such as carbon monoxide, nitrogen oxides, and formaldehyde in cigarette smoke, the activated carbon fiber can quickly adsorb and fix them, significantly reducing the content of these harmful gases in the smoke, and can reduce the content of tiny particles in the smoke to a lower level than when using aerogel or activated carbon fiber alone, providing smokers with cleaner smoke; At the same time, when the cigarette burns to the position of the aerogel composite material, there are a large number of active sites on the surface of the activated carbon fiber. During the combustion process of the cigarette, these active sites can adsorb free radicals generated by the combustion; free radicals are the key factor in maintaining the continuous combustion reaction. The activated carbon fiber interrupts the chain transmission of the combustion reaction by adsorbing free radicals, thereby inhibiting the further development of the cigarette combustion reaction; when the thermal insulation performance of the aerogel composite material and the adsorption performance of the activated carbon fiber for free radicals work together in long-term use, the durability of the flame retardant performance is maintained; as the burning time of the cigarette increases, the aerogel continues to block heat, reducing the impact of heat on the activated carbon fiber, so that the activated carbon fiber can maintain its adsorption activity for free radicals for a long time and continue to inhibit the combustion reaction; this synergistic durability of performance ensures that the flame retardant effect can be effectively exerted throughout the entire cigarette combustion process, reducing the time that the cigarette continues to burn without external force.

[0022] Example 3:

[0023] Figures 1 to 4 As shown; before the aerogel composite material is prepared into a sheet, a metal oxide is added to the raw material of the aerogel composite material; Antimony trioxide is used as the metal oxide.

[0024] Here’s how it works: Before the aerogel composite material is prepared into a sheet shape, antimony trioxide is added to the raw materials of the aerogel composite material. When antimony trioxide is used in combination with the aerogel composite material for cigarette flame retardancy, when the cigarette burns to the position of the aerogel composite material, the cigarette sparks will contact the aerogel composite material. At this time, the antimony trioxide reacts with halides and other substances generated during the combustion process to generate a carbonaceous structure at the active contact position of the aerogel composite material and the cigarette. The carbonaceous structure blocks the position where the cigarette continues to burn, and can further block heat transfer through the contact between the spark and the subsequent cigarette body, effectively inhibiting the combustion reaction.

[0025] Example 4:

[0026] Figures 1 to 4 As shown; in step one, after coating the glue coating area, adding plant extract to the glue coating area; Eugenol granules are used as plant extract; Before coating the eugenol particles on the tipping paper, nano-silica material is added to the clove powder particles, and then the aerogel composite material is coated on the surface of the eugenol and silica materials.

[0027] Here’s how it works: In step 1, after glue is applied to the glue-coated area, eugenol particles are added to the glue. After the eugenol particles are laid on the glue, a sheet-like aerogel composite material is laid on the clove powder particles, and a nano-silica material is added inside the eugenol particles so that the clove powder particles and the nano-silica material are mixed and located between the tipping paper and the aerogel composite material. During the burning process of cigarettes, eugenol particles can adjust the composition and properties of the smoke produced by the burning cigarettes; they can make the smoke softer and more delicate, reduce the irritation and roughness in the smoke, and make smokers feel a more comfortable aroma experience during the smoking process; at the same time, nano-silica material is added to eugenol. Nano-silica has a small particle size and a large specific surface area, which can form a porous structure and can physically intercept tiny particles in the smoke, playing a filtering role; at the same time, nano-silica itself is odorless and will not change the aroma of eugenol; and it can be well mixed with eugenol without chemical reactions that affect the aroma components; Nano-silica material is added to the eugenol particles. Nano-silica has good high-temperature resistance and can maintain stable physical and chemical properties at high temperatures. When mixed with eugenol, it can improve the high-temperature resistance of the entire system to a certain extent because it can disperse heat and reduce the thermal decomposition and volatilization of eugenol at high temperatures. At the same time, nano-silica has good thermal conductivity. When nano-silica is laid on the outer circle of the aerogel composite material, the heat of the cigarette spark is transferred to the aerogel composite material. It can be transferred out of the cigarette through the nano-silica material on the outside, and the heat generated by the cigarette burning is dispersed to a larger area; this can reduce the local temperature of the burning area, thereby slowing down the combustion speed and enhancing the flame retardant properties of the cigarette.
