[0036] See also Figure 1 and Figure 2 The embodiment of the present application provides a package 10. The package 10 includes a carrier layer 11, a flame retardant layer 13 and an impermeability layer 15. The carrier layer 11 includes a first side 111 and a second side 113 opposite to each other. One of the flame retardant layer 13 and the impermeability layer 15 is disposed on the first side 111 of the carrier layer 11, and the other is disposed on the second side 113 of the carrier layer 11. The flame retardant layer 13 is used to hinder the burning of the carrier layer 11, and the impermeability layer 15 is used to prevent liquid penetration.
[0037] In some embodiments, the cross-sectional shape of the carrier layer 11 may be circular, square, triangular or elliptical, etc., which is not limited here. The carrier layer 11 can be used to support the aerosol generating matrix 200. Among them, the carrier layer 11 is made of at least one of aluminum hydroxide, magnesium hydroxide, titanium oxide, kaolin and diatomaceous earth and plant fiber, and the plant fiber includes at least one of coniferous wood pulp, broadleaf wood pulp, cotton lint pulp and hemp pulp. Among them, the carrier layer 11 is made of at least one inorganic substance of aluminum hydroxide, magnesium hydroxide, titanium oxide, kaolin and diatomaceous earth and plant fiber. Since plant fiber is a renewable organic material, it can reduce the impact on the environment through natural degradation and biodegradation. Therefore, the use of plant fiber and at least one of aluminum hydroxide, magnesium hydroxide, titanium oxide, kaolin and diatomaceous earth to make the carrier layer 11 can improve the degradability of the carrier layer 11, thereby reducing or even avoiding the impact of the carrier layer 11 on the environment.
[0038] In some embodiments, the weight of the carrier layer 11 is [20 g / m 2 , 75g / m 2 Specifically, in some embodiments, the weight of the carrier layer 11 may be 20 g / m 2 , 25g / m 2 , 30g / m 2 , 35g / m 2 , 40g / m 2 , 45g / m 2 , 50g / m 2 , 55g / m 2 , 60g / m2 , 65g / m 2 , 70g / m 2 and 75g / m 2 Since the flame retardant layer 13 is made by coating the flame retardant liquid on the first side 111 of the carrier layer 11 and / or the second side 113 of the carrier layer 11, if the weight of the carrier layer 11 is less than 20g / m2, less flame retardant liquid is coated on the carrier layer 11, resulting in poor effect of the flame retardant layer 13 on preventing the combustion of the carrier layer 11; if the weight of the carrier layer 11 is greater than 75g / m2, the flame retardant liquid coated on the carrier layer 11 is less, resulting in poor effect of the flame retardant layer 13 on preventing the combustion of the carrier layer 11. 2 , the flame retardant liquid coated on the carrier layer 11 is too much, resulting in poor air permeability of the carrier layer 11, thereby affecting the amount of aerosol generated. In the embodiment of the present application, the weight of the carrier layer 11 is [20g / m 2 , 75g / m 2 ], thereby, on the one hand, it can avoid less flame retardant liquid coated on the carrier layer 11, thereby ensuring the flame retardant layer 13's hindering effect on the combustion of the carrier layer 11; on the other hand, it can improve the air permeability of the carrier layer 11, thereby ensuring that the external air can contact the aerosol generating matrix 200 through the carrier layer 11, thereby increasing the amount of aerosol generated by the aerosol generating matrix 200 when heated, and ensuring the user's smoking taste.
[0039] In some embodiments, the flame retardant layer 13 may be disposed on the first side 111 of the carrier layer 11 and / or the second side 113 of the carrier layer 11, so as to ensure that the flame retardant layer 13 has an effect of hindering the burning of the carrier layer 11. For example, the flame retardant layer 13 may be disposed on the first side 111 of the carrier layer 11. For another example, the flame retardant layer 13 may be disposed on the second side 113 of the carrier layer 11. For another example, the flame retardant layer 13 may be disposed on the first side 111 of the carrier layer 11 and the second side 113 of the carrier layer 11. The embodiments of the present application are described only by taking the flame retardant layer 13 disposed on the first side 111 of the carrier layer 11 and the anti-seepage layer 15 disposed on the first side 113 of the carrier layer 11 as an example.
[0040] In some embodiments, the flame retardant layer 13 is provided with a gap 133 for gas to flow to the carrier layer 11. Specifically, in some embodiments, the flame retardant layer 13 may include a plurality of flame retardant portions 131, and there is a gap 133 between adjacent flame retardant portions 131. Therefore, compared with the first side 111 of the carrier layer 11 being entirely covered with the flame retardant layer 13 (i.e., there is no gap in the flame retardant portion 131), the gap 133 between adjacent flame retardant portions 131 can improve the air permeability of the carrier layer 11, facilitate energy exchange, and ensure that the outside air can pass through the carrier layer 11 and contact the aerosol generating substrate 200 during normal inhalation, thereby ensuring or even improving the amount of aerosol generated by the aerosol generating substrate 200 when heated, ensuring the user's inhalation taste and improving the aerosol generation efficiency.
[0041] In some embodiments, the flame retardant portion 131 is annular. Specifically, the plurality of flame retardant portions 131 are annular and surround the first side 111 of the carrier layer 11. The arrangement of the plurality of flame retardant portions 131 can also prevent the aerosol generating product 100 from burning and being damaged when the aerosol generating product 100 comes into contact with an open flame due to user misoperation or other reasons. It should be noted that, in some embodiments, when the flame retardant portion 131 is annular, the cross-sectional shape of the carrier layer 11 is circular.
[0042] In some embodiments, the flame retardant layer 13 is made of a flame retardant and a solvent, wherein the flame retardant is a material with flame retardant properties; the solvent is a material that dissolves the flame retardant, and the solubility of the flame retardant in the solvent may be greater than or equal to 60%. In the present application, the flame retardant may include at least one of aluminum hydroxide, magnesium hydroxide, titanium oxide, kaolin and diatomaceous earth. The solvent includes amino silicone oil. Among them, aluminum hydroxide, magnesium hydroxide, titanium oxide, kaolin and diatomaceous earth are all inorganic substances. After the flame retardant layer 13 is supported by the material and the solvent, the ignition point of the flame retardant layer 13 is relatively high, thereby reducing the flammability of the aerosol generating product 100, reducing or even avoiding the possibility of the aerosol generating product 100 being ignited, and ensuring the safety of the aerosol generating product 100. In addition, amino silicone oil is an organic compound, usually composed of a variety of organic components and silicates, and can be degraded by microbial degradation or photodegradation. Moreover, when the solvent includes amino silicone oil, using at least one of aluminum hydroxide, magnesium hydroxide, titanium oxide, kaolin and diatomaceous earth and amino silicone oil to form the flame retardant layer 13 can reduce the flammability of the flame retardant layer 13 and reduce or even avoid the possibility of the aerosol generating product 100 being ignited.
[0043] In some embodiments, the mass percentage concentration of the flame retardant is [5.0%, 60.0%]. The flame retardant is an additive used to improve the flame retardant ability of the material, that is, when the flame retardant layer 13 is made of the flame retardant and is disposed on the first side 111 of the carrier layer 11, the flame retardant ability of the aerosol generating article 100 is improved. In some embodiments, the mass percentage concentration of the flame retardant can be any one of 5.0%, 10.0%, 15.0%, 20.0%, 25.0%, 30.0%, 35.0%, 40.0%, 45.0%, 50.0%, 55.0% and 60.0%, or any value between any two values. If the mass percentage concentration of the flame retardant is less than 5.0%, the flame retardant effect of the flame retardant layer 13 made of the flame retardant with a mass percentage concentration less than 5.0% is poor, and the effect of hindering the combustion of the carrier layer 11 cannot be achieved. If the mass percentage concentration of the flame retardant is greater than 60.0%, the amount of flame retardant required to make the flame retardant layer 13 is too much, exceeding the maximum load capacity of the carrier layer 11 for the flame retardant, thereby causing damage to the package 10. In the embodiment of the present application, the mass percentage concentration of the flame retardant is [5.0%, 60.0%], thereby, on the one hand, the flame retardant effect of the flame retardant layer 13 made of the flame retardant can be improved, ensuring that the flame retardant layer 13 can hinder the combustion of the carrier layer 11; on the other hand, it can avoid the excessive amount of flame retardant causing the carrier layer 11 to be unable to bear, thereby ensuring the normal production of the package 10. In addition, the mass percentage concentration of the flame retardant of [5.0%, 60.0%] can also reduce the production cost of the flame retardant layer 13.
[0044] The mass percentage concentration of the solvent is [40.0%, 95.0%]. In some embodiments, the mass percentage concentration of the solvent may be any one of 40.0%, 45.0%, 50.0%, 55.0%, 60.0%, 65.0%, 70.0%, 75.0%, 80.0%, 85.0%, 90.0% and 95.0%, or any value between any two values. In one example, when the mass percentage concentration of the solvent is 45.0%, the mass percentage concentration of the flame retardant is 55.0%. If the mass percentage concentration of the solvent is less than 40.0%, when the flame retardant and the solvent are mixed to make a flame retardant liquid, the flame retardant cannot be completely dissolved, thereby affecting the flame retardant effect of the flame retardant layer 13. If the mass percentage concentration of the solvent is greater than 95.0%, the amount of solvent required to make the flame retardant layer 13 is too much, exceeding the maximum carrying capacity of the carrier layer 11 for the solvent, thereby causing damage to the package 10. In the embodiment of the present application, the mass percentage concentration of the solvent is [40.0%, 95.0%]. Therefore, on the one hand, the flame retardant effect of the flame retardant layer 13 can be improved to ensure that the flame retardant layer 13 can hinder the combustion of the carrier layer 11; on the other hand, the excessive amount of solvent can be avoided so that the carrier layer 11 cannot bear the load, thereby ensuring the normal production of the package 10.
[0045] See also Figure 3 , in some embodiments, in the length direction of the carrier layer 11, the width S of each flame retardant portion 131 is [0.3mm, 1.0mm]. Specifically, in some embodiments, the width S of each flame retardant portion 131 may be any one of 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm and 1.0mm, or any value between any two values. If the width S of each flame retardant portion 131 in the length direction of the carrier layer 11 is less than 0.3mm, the flame retardancy of the flame retardant layer 13 is poor, that is, the flame retardant layer 13 has a poor effect of hindering the combustion of the carrier layer 11, resulting in the aerosol generating product 100 being easily burned and damaged. If the width S of each flame retardant portion 131 in the length direction of the carrier layer 11 is greater than 1.0mm, the air permeability of the carrier layer 11 is poor, thereby affecting the amount of aerosol generated. In the embodiment of the present application, in the length direction of the carrier layer 11, the width S of each flame retardant portion 131 is [0.3mm, 1.0mm]. Therefore, on the one hand, the flame retardant layer 13 can prevent the combustion of the carrier layer 11 from being damaged by combustion, and on the other hand, the air permeability of the carrier layer 11 can be improved to ensure that the outside air can pass through the carrier layer 11 and contact the aerosol generating matrix 200, thereby increasing the amount of aerosol generated by the aerosol generating matrix 200 when heated, and ensuring the user's inhalation taste. In addition, in the length direction of the carrier layer 11, the width S of each flame retardant portion 131 is [0.3mm, 1.0mm], which can also improve the appearance of the package 10.
[0046] In some embodiments, in the length direction of the carrier layer 11, the distance D between two adjacent flame retardant portions 131 is [0.1mm, 2.0mm]. Specifically, in some embodiments, the distance D between two adjacent flame retardant portions 131 can be any one of 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm and 2.0mm or any value between any two values. If the distance D between two adjacent flame retardant portions 131 is 0mm, that is, the flame retardant layer 13 completely covers the first side 111 of the carrier layer 11, then there is no gap 133 in the flame retardant layer 13, resulting in poor air permeability of the carrier layer 11, thereby affecting the amount of aerosol generated. If the distance D between two adjacent flame retardant portions 131 is greater than 2.0 mm, the distance D between two adjacent flame retardant portions 131 is too large. When the aerosol generating product 100 contacts an open flame due to user misoperation or other reasons, the flame retardant layer 13 cannot prevent the burning of the carrier layer 11, thereby causing the aerosol generating product 100 to burn and be damaged. In the embodiment of the present application, in the length direction of the carrier layer 11, the distance D between two adjacent flame retardant portions 131 is (0 mm, 2.0 mm], thereby, on the one hand, the air permeability of the carrier layer 11 can be improved, ensuring that the outside air can pass through the carrier layer 11 and contact the aerosol generating matrix 200, thereby increasing the amount of aerosol generated by the aerosol generating matrix 200 when heated, and ensuring the user's inhalation taste; on the other hand, the flame retardant layer 13 can prevent the burning of the carrier layer 11, thereby preventing the aerosol generating product 100 from burning and being damaged.
[0047] In some embodiments, in order to ensure the amount of aerosol generated by the aerosol-generating product 100, a large amount of atomizer (propylene glycol and glycerol, etc.) is usually added when making the aerosol-generating substrate 200. If the carrier layer 11 is in direct contact with the aerosol-generating substrate 200, the atomizer will seep onto the carrier layer 11 during the long-term storage of the aerosol-generating product 100, resulting in mottled marks on the carrier layer 11, affecting the clean appearance of the aerosol-generating product 100. Therefore, in the present application, the provision of the impermeable layer 15 can prevent liquid penetration, that is, the impermeable layer 15 can prevent the atomizer in the aerosol-generating substrate 200 from seeping into the carrier layer 11, avoiding the atomizer from forming mottled marks on the carrier layer 11, and ensuring the clean appearance of the aerosol-generating product 100.
[0048] In some embodiments, the impermeable layer 15 is made of natural biofilm material, biowax, surfactant and solvent, wherein the natural biofilm material, biowax, surfactant and solvent are materials with biodegradability, good film-forming property and no chemical reaction with the base paper material, and the mutual solubility rate between the natural biofilm material, biowax, surfactant and solvent is greater than or equal to 60%. Thus, in the case where the impermeable layer 15 is discarded or lost, the impermeable layer 15 can be degraded by substances such as microorganisms, bacteria or fungi, thereby reducing or even avoiding the pollution of the impermeable layer 15 to the environment. It should be noted that in some embodiments, the natural biofilm material includes at least one of biopolysaccharides, chitosan, fatty acid esters and stearic acid. The biowax includes at least one of beeswax, candlewood wax and palm wax. The surfactant includes at least one of Tween 80, Tween 60, glycerol and polyethylene glycol. The solvent includes water.
[0049] In some embodiments, the mass percentage concentration of natural biofilm material is [1.0%, 30.0%]. In some embodiments, the mass percentage concentration of natural biofilm material can be any one of 1.0%, 5.0%, 10.0%, 15.0%, 20.0%, 25.0% and 30.0% or any value between any two values. The mass percentage concentration of biowax is [0.1%, 20.0%]. In some embodiments, the mass percentage concentration of biowax can be any one of 0.1%, 1.0%, 5.0%, 7.0%, 10.0%, 13.0%, 15.0%, 17.0% and 20.0% or any value between any two values. The mass percentage concentration of surfactant is [0.1%, 20.0%]. In certain embodiments, the mass percentage concentration of the surfactant may be any one of 0.1%, 1.0%, 5.0%, 7.0%, 10.0%, 13.0%, 15.0%, 17.0% and 20.0%, or any value between any two values. The mass percentage concentration of the dissolving agent is [30.0%, 70.0%]. In certain embodiments, the mass percentage concentration of the dissolving agent may be any one of 30.0%, 35.0%, 40.0%, 45.0%, 50.0%, 55.0%, 60.0%, 65.0% and 70.0%, or any value between any two values.
[0050] In one example, the impermeable layer 15 is composed of natural biofilm material, biowax, surfactant and solvent. Among them, the mass percentage concentration of natural biofilm material is 10.0%; the mass percentage concentration of biowax is 20.0%; the mass percentage concentration of surfactant is 10.0%; the mass percentage concentration of solvent is 60.0%. It should be noted that in some embodiments, the mass percentage concentrations of natural biofilm material, biowax, surfactant and solvent may vary according to usage and requirements (for example, different parameters such as the size or thickness of the impermeable layer 15 in different aerosol generating products 100 are different).
[0051] In the package 10 of the embodiment of the present application, the carrier layer 11 includes a first side 111 and a second side 113 opposite to each other, and one of the flame retardant layer 13 and the waterproof layer 15 is arranged on the first side 111 of the carrier layer 11, and the other is arranged on the second side 113 of the carrier layer 11. Therefore, the flame retardant layer 13 can hinder the combustion of the carrier layer 11, thereby preventing the package 10 from coming into contact with an open flame due to user misoperation or other reasons, thereby preventing the package 10 from being damaged. In addition, the setting of the flame retardant layer 13 can also avoid safety problems such as fire when the package 10 is discarded.
[0052] In addition, the provision of the anti-seepage layer 15 can prevent liquid penetration, avoid the liquid from forming mottled marks on the carrier layer 11, and ensure the cleanliness of the appearance of the package 10.
[0053] See also Figure 1 and Figure 2 The embodiment of the present application further provides an aerosol generating product 100. The aerosol generating product 100 comprises an aerosol generating substrate 200 and a package 10 of any of the above embodiments, wherein the package 10 is used to support the aerosol generating substrate 200.
[0054] The aerosol generating substrate 200 is an element that can generate an aerosol after being heated. The form of the aerosol generating substrate 200 can be fully solid or semi-solid. It should be noted that in some embodiments, the aerosol generating substrate 200 can be a cylindrical structure similar to a cigarette, or a sheet structure, a strip structure or a block structure. The aerosol can be visible or invisible and can include vapor (for example, fine particulate matter in a gaseous state, which is usually liquid or solid at room temperature) and liquid droplets of gas and condensed vapor. The "aerosol" herein covers the aerosol generated when the aerosol generating substrate 200 in the heated aerosol generating product 100 is heated.
[0055] In some embodiments, the aerosol generating article 100 may be a sheet structure, in which case the aerosol generating substrate 200 is also a sheet structure. Specifically, in some embodiments, when the aerosol generating substrate 200 is in a fully solid state, the aerosol generating substrate 200 may be prepared into a sheet structure by a process such as rolling or thick slurry. In this case, the carrier layer 11 may be a sheet structure, and after the aerosol generating substrate 200 is manufactured, the aerosol generating substrate 200 may be placed between two carrier layers 11 to form the aerosol generating article 100; or the carrier layer 11 may be a tubular structure, and after the aerosol generating substrate 200 is manufactured, the aerosol generating substrate 200 may be extended into the carrier layer 11 through one end of the carrier layer 11, and the second side 113 of the carrier layer 11 is opposite to the aerosol generating substrate 200.
[0056] In other embodiments, the aerosol generating article 100 may be a cylindrical structure, in which case the aerosol generating substrate 200 is also a cylindrical structure. Specifically, in one embodiment, when the aerosol generating substrate 200 is in a fully solid state, the aerosol generating substrate 200 may be prepared into a cylindrical structure by a process such as rolling or thick slurry. At this time, the carrier layer 11 may be a cylindrical structure. After the aerosol generating substrate 200 is manufactured, the aerosol generating substrate 200 may be extended into the carrier layer 11 through one end of the carrier layer 11, and the second side 113 of the carrier layer 11 is opposite to the aerosol generating substrate 200. In another embodiment, when the aerosol generating substrate 200 is in a fully solid state, the aerosol generating substrate 200 may be prepared into a sheet structure by a process such as rolling or thick slurry. At this time, the carrier layer 11 can also be a sheet structure. When making the aerosol generating product 100, the aerosol generating matrix 200 with a sheet structure can be firstly spread flat on the carrier layer 11 with a sheet structure, and the carrier layer 11 and the aerosol generating matrix 200 can be rolled together to form a cylindrical structure.
[0057] In the aerosol generating product 100 of the embodiment of the present application, the carrier layer 11 includes a first side 111 and a second side 113 opposite to each other, the second side 113 of the carrier layer 11 is opposite to the aerosol generating substrate 200, and the flame retardant layer 13 is arranged on the first side 111 of the carrier layer 11, thereby, the flame retardant layer 13 can hinder the burning of the carrier layer 11, and prevent the package 10 from contacting with an open flame due to user misoperation or other reasons, resulting in burning damage to the package 10, and the setting of the flame retardant layer 13 can also avoid safety problems such as fire when the package 10 is discarded. In addition, the setting of the anti-seepage layer 15 can prevent liquid penetration and prevent the liquid from forming mottled marks on the carrier layer 11, thereby ensuring the cleanliness of the appearance of the aerosol generating product 100 and the internal cleanliness of the aerosol generating device.
[0058] See also Figures 1 to 3The present application also provides a method for preparing a package 10. The method for preparing the package 10 includes:
[0059] 01: coating a flame retardant liquid on the first side 111 of the carrier layer 11; and
[0060] 03: The flame retardant liquid is dried to form a flame retardant layer 13 . The flame retardant layer 13 is provided with a gap 133 for gas to flow toward the carrier layer 11 .
[0061] Specifically, after the flame retardant and the solvent are mixed to prepare the flame retardant liquid, a flame retardant having a gram weight of [20 g / m 2 , 75g / m 2 ] is provided on a carrier layer 11, and a flame retardant liquid is coated on a first side 111 of the carrier layer 11, and then the flame retardant liquid is dried to form a flame retardant layer 13. Thus, the flame retardant layer 13 can hinder the combustion of the carrier layer 11, and the flame retardant layer 13 is provided with a gap 133 for gas to flow to the carrier layer 11, thereby improving the air permeability of the carrier layer 11, ensuring that the external gas can contact the aerosol generating matrix 200, and thus increasing the amount of aerosol generated. It should be noted that, in some embodiments, the flame retardant liquid is made of a flame retardant and a solvent. The flame retardant includes at least one of aluminum hydroxide, magnesium hydroxide, titanium oxide, kaolin and diatomaceous earth. The solvent includes amino silicone oil. The mass percentage concentration of the flame retardant is [5.0%, 60.0%]. The mass percentage concentration of the solvent is [40.0%, 95.0%].
[0062] In some embodiments, the temperature for drying the flame retardant liquid is [30°C, 120°C]. In some embodiments, the temperature for drying the flame retardant liquid may be any one of 30°C, 40°C, 50°C, 60°C, 70°C, 80°C, 90°C, 100°C, 110°C and 120°C, or any value between any two values. If the temperature for drying the flame retardant liquid is less than 30°C, the drying time of the flame retardant liquid may be longer, affecting the production efficiency of the flame retardant layer 13. If the temperature for drying the flame retardant liquid is greater than 120°C, some substances in the flame retardant liquid may react (such as chemical changes or decomposition reactions, etc.) during the drying process of the flame retardant liquid, thereby affecting the flame retardant effect of the flame retardant layer 13. Therefore, in the embodiment of the present application, the temperature for drying the flame retardant liquid is [30°C, 120°C]. On the one hand, it can shorten the drying time and improve the production efficiency of the flame retardant layer 13; on the other hand, it can prevent some substances in the flame retardant liquid from reacting, thereby ensuring the flame retardant effect of the flame retardant layer 13.
[0063] See also Figures 1 to 3 In some embodiments, the method for preparing the package 10 further comprises:
[0064] 05: Applying an impermeable liquid on the second side 113 of the carrier layer 11; and
[0065] 07: Drying the flame retardant liquid to form an impermeable layer 15.
[0066] Specifically, after the anti-seepage liquid is prepared by mixing the natural biofilm material, biowax, surfactant and solvent, a 20 g / m 2 , 75g / m 2 ] and apply an impermeable liquid on the second side 113 of the carrier layer 11, and then dry the impermeable liquid to form an impermeable layer 15. As a result, the impermeable layer 15 can prevent the atomizer in the aerosol generating matrix 200 from seeping into the carrier layer 11, avoid the atomizer from forming mottled marks on the carrier layer 11, and ensure the clean appearance of the aerosol generating product 100. It should be noted that in some embodiments, the impermeable liquid is made of natural biofilm material, biological wax, surfactant and solvent. The natural biofilm material includes at least one of biopolysaccharide, chitosan, fatty acid ester and stearic acid. The biological wax includes at least one of beeswax, candlewood wax and palm wax. The surfactant includes at least one of Tween 80, Tween 60, glycerol and polyethylene glycol; the solvent includes water. The mass percentage concentration of natural biofilm material is [1.0%, 30.0%]; the mass percentage concentration of biowax is [0.1%, 20.0%]; the mass percentage concentration of surfactant is [0.1%, 20.0%]; and the mass percentage concentration of solvent is [30.0%, 70.0%].
[0067] In some embodiments, the temperature for drying the anti-seepage liquid is [30°C, 120°C]. In some embodiments, the temperature for drying the anti-seepage liquid may be any one of 30°C, 40°C, 50°C, 60°C, 70°C, 80°C, 90°C, 100°C, 110°C and 120°C or any value between any two values. If the temperature for drying the anti-seepage liquid is less than 30°C, the drying time of the anti-seepage liquid may be longer, affecting the production efficiency of the anti-seepage layer 15. If the temperature for drying the anti-seepage liquid is greater than 120°C, some substances in the anti-seepage liquid may react (such as chemical changes or decomposition reactions, etc.) during the drying process of the anti-seepage liquid, thereby affecting the anti-seepage effect of the obtained anti-seepage liquid. Therefore, in the embodiment of the present application, the temperature for drying the anti-seepage liquid is [30°C, 120°C]. On the one hand, it can shorten the drying time and improve the production efficiency of the anti-seepage layer 15; on the other hand, it can prevent some substances in the anti-seepage liquid from reacting, thereby ensuring the anti-seepage effect of the anti-seepage layer 15.
