DETAILED DESCRIPTION

[0015] In order to have a clearer understanding of the technical features, purposes and effects of the present application, the present application will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present application and do not constitute a limitation on the scope of protection of the present application.

[0016] The present application proposes a method for preparing a liquid-conducting component, comprising the following steps:

[0017] Step 100, pretreatment: irradiating the cellulose nonwoven fabric to generate free radicals on the surface, and then stretching the cellulose nonwoven fabric to obtain a pretreated cellulose nonwoven fabric.

[0018] In some embodiments, the cellulose nonwoven fabric includes natural cellulose and / or regenerated cellulose. The natural cellulose may include at least one of cotton fiber and hemp fiber. The regenerated cellulose may include at least one of viscose fiber, lyocell and cuprammonium fiber. It is understandable that the cellulose nonwoven fabric may include one fiber, such as cotton fiber or viscose fiber. The cellulose nonwoven fabric may also include two fibers, such as hemp fiber and lyocell. The cellulose nonwoven fabric may also include three fibers, such as viscose fiber, lyocell and cuprammonium fiber. The cellulose nonwoven fabric may be a cellulose spunlace nonwoven fabric. The gram weight of the cellulose nonwoven fabric (i.e., the weight of the cellulose nonwoven fabric per square meter) is 40 g / m 2 ~120g / m 2 , you can choose 40g / m 2 , 60g / m 2 , 80g / m 2 , 100g / m 2 , 120g / m 2 wait.

[0019] The irradiation treatment uses electron beam irradiation, and the irradiation dose is 50kGy~200kGy, and 50kGy, 100Kgy, 120kGy, 150kGy, 200kGy, etc. can be selected. It can be understood that the irradiation dose can be adjusted according to the electron beam current, voltage and traction speed. The purpose of irradiation is to generate free radicals on the surface of cellulose so that nanocellulose can better combine with it and prevent it from falling off, but excessive radiation will cause degradation of the fiber material. Therefore, the irradiation dose should be controlled as much as possible under the premise of satisfying the modification effect.

[0020] Drawing can be done by drawing the cellulose nonwoven fabric out under the action of a drawing machine. Drawing can change the morphology and physical properties of the fibers in the cellulose nonwoven fabric, and improve the mechanical properties and processing properties of the fibers.

[0021] Step 200, modification treatment: spraying the nanocellulose solution on the surface of the pre-treated cellulose non-woven fabric to allow the nanocellulose to bind to the surface of the cellulose non-woven fabric, thereby obtaining a modified cellulose non-woven fabric.

[0022] The nanocellulose solution includes solvent water, nanocellulose with a mass percentage of 0.5% to 3% and an activator with a mass percentage of 0.1% to 2%, wherein the mass percentage of nanocellulose can be selected from 0.5%, 1%, 1.5%, 2%, 3%, etc., and the mass percentage of the activator can be selected from 0.1%, 0.5%, 1.0%, 1.5%, 2%, etc. The diameter of the nanocellulose is 10nm to 500nm, and 10nm, 100nm, 200nm, 300nm, 400nm, 500nm, etc. can be selected; the aspect ratio of the nanocellulose is 20 to 100, and 20, 40, 60, 80, 100, etc. can be selected. The activator activates the nanocellulose, and the activator can be persulfate, and the persulfate can be potassium persulfate or ammonium persulfate, and the activator can also use other water-soluble activators.

[0023] In this step, the nanocellulose solution is first heated to activate the persulfate therein, and the nanocellulose solution is heated to 60°C to 80°C, and the heating temperature can be 60°C, 65°C, 70°C, 75°C, 80°C, etc. Then 100g to 1000g (heated) nanocellulose solution is sprayed on each square meter of the pre-treated cellulose non-woven fabric, and the uniformity of the spraying is ensured, so as to achieve the modification of the cellulose non-woven fabric by nanocellulose. The modified nanocellulose non-woven fabric is used as a liquid guide, which can effectively improve the uniformity and stability of the atomized matrix during the atomization process and enhance the taste. Among them, the spraying amount of the nanofiber solution on each square meter of the pre-treated cellulose non-woven fabric can be selected as 100g, 300g, 500g, 800g, 1000g, etc. If the spraying amount is too little (less than 100g), it will not improve the taste. If the spraying amount is too much (higher than 1000g), the liquid guide performance will deteriorate and it is easy to have a paste taste.

[0024] Step 300, post-processing: laminating the modified cellulose non-woven fabric, followed by drying and shaping, surface cleaning and drying to obtain a liquid guide member.

[0025] The lamination process is to improve the bonding force between the nanocellulose and the cellulose non-woven fabric. The lamination process can be performed by roller lamination. The lamination gap of the roller is selected according to the gram weight of the cellulose non-woven fabric. Generally, the cellulose non-woven fabric with a higher gram weight will have a higher thickness, and the lamination gap will also increase accordingly. In some embodiments, the lamination gap of the roller is less than 50% of the thickness of the cellulose non-woven fabric.

[0026] The drying temperature for drying and shaping is 100℃~150℃, and 100℃, 110℃, 120℃, 130℃, 140℃, 150℃, etc. can be selected; the drying time is 20min~40min, and 20min, 25min, 30min, 35min, 40min, etc. can be selected. There is still nanocellulose that is not firmly bonded on the cellulose non-woven fabric after drying and shaping, and the surface is cleaned to remove excess nanocellulose. Surface cleaning is to immerse the dried and shaped modified cellulose non-woven fabric in water for cleaning. Furthermore, the cleaned modified cellulose non-woven fabric is dried and rolled up, and a liquid guide part can be obtained after cutting, wherein the cutting size, shape, etc. can be selected according to actual needs and are not limited here.

[0027] The present application also proposes a liquid guide, which is made by any of the above-mentioned methods for preparing a liquid guide, wherein the liquid guide comprises a cellulose non-woven fabric, and nanocellulose is distributed in the cellulose non-woven fabric. By using the nanocellulose-modified cellulose non-woven fabric as the liquid guide, the uniformity and stability of the atomization matrix during the atomization process can be effectively improved, and the liquid absorption performance can be improved.

[0028] The present application also proposes an atomization device, which includes the above-mentioned liquid guide. In some embodiments, the atomization device includes a housing and an atomization core, and the atomization core includes the above-mentioned liquid guide and a heating element. When the atomization device is working, the liquid guide absorbs the atomization matrix, and the heating element of the atomization core heats and atomizes the atomization matrix on the liquid guide. The liquid guide of the atomization core adopts a cellulose non-woven fabric modified by nanocellulose, and has stable liquid absorption performance, thereby improving the taste, smoke volume and user experience of the atomization device.

[0093] The dried modified cellulose nonwoven fabrics of the above-mentioned Examples 1-5, Comparative Example 1 and Comparative Example 2 were cut and processed into liquid guides, and the cutting specifications were 7.5mm*60mm*6 layers. The same electronic atomization device was selected for installation test, and the taste was scored every 500 puffs. When the amount of atomization matrix was insufficient, it was supplemented. The scoring criteria were divided into four dimensions, namely sweetness, coolness, aroma and fullness. The score of each dimension was 0 to 5 points from low to high. The average score of the four dimensions was taken as the final score. The test results are shown in Table 1.

[0094] Table 1 Taste test results

Therefore, the use of the liquid guide of the present application makes the electronic atomization device have a better taste.
