Abstract
Description
Technical Field
[0001] This invention relates to the field of functional materials for clothing, and more particularly to a phase change aerogel composition with temperature regulating function and textiles thereof. Background Technology
[0002] With the continuous advancement of science and technology, people's living standards have improved significantly. As clothing has become an indispensable part of people's lives, people's functional requirements for their clothing have also increased. In the cold season, people want textiles with warm properties to replace the traditional, heavy, and cumbersome way of wearing clothes; in the hot summer, people want textiles with cool and heat-insulating properties so that they don't feel stuffy and feel as if they are in an air-conditioned room.
[0003] Aerogel, currently the lightest and most heat-insulating nano-ceramic material in the world, offers a heat insulation effect of over 10°C compared to ordinary fabrics. In summer, it effectively prevents heat transfer; in winter, it reduces heat loss from the body, achieving a heat-generating and heat-locking effect, making it a winter warmth essential.
[0004] The properties of aerogels are determined by their microstructure, especially their porous structure, with the size and distribution of pores playing a crucial role. Therefore, the regulation of aerogel pore structure has attracted considerable attention. Summary of the Invention
[0005] In order to achieve the control of the pore structure of aerogel, the present invention aims to provide a phase change aerogel composition and textile with temperature regulation function. The composition can increase the internal pore size of the aerogel, can encapsulate more phase change material, improve the phase change function, and enable the phase change aerogel textile to store energy and slow down the temperature rise. When the external temperature drops, it can release energy and slow down the temperature drop, thereby forming a microclimate with a basically constant temperature between the clothing and human skin.
[0006] To achieve the above objectives, the technical solution of the present invention is: a phase change aerogel composition with temperature regulation function, comprising 5-10% by mass of phase change material, 80-95% by mass of binder, and the remainder being aerogel;
[0007] The aerogel can be at least one of a dual-network phase change aerogel and a silica aerogel.
[0008] The phase change material can be at least one of the following: dual-network phase change aerogel, PEG, paraffin, fatty acid, and sugar alcohol.
[0009] Furthermore, the silica aerogel is modified by treatment with surfactants and acids.
[0010] Furthermore, the molar ratio of silicon to surfactant in the silica aerogel is 1:2 to 1:4.
[0011] Furthermore, the surfactant is selected from chlorosulfonic acid and / or chlorosulfonate.
[0012] Furthermore, the acid is hydrochloric acid or sulfuric acid.
[0013] Furthermore, the phase change material is selected from at least one of commercially available PEG, paraffin, fatty acids, and sugar alcohols; the molecular weight of the PEG is 1500-20000.
[0014] The adhesive is selected from one or more of commercially available methyl acrylate, ethyl acrylate, and butyl acrylate;
[0015] The silica aerogel is selected from at least one of hydrophilic silica aerogel and hydrophobic silica aerogel.
[0016] A textile using the aforementioned temperature-regulating phase change aerogel composition includes a textile fabric, wherein the phase change aerogel composition is premixed, centrifuged, and then sprayed, impregnated, or brushed onto the surface of the textile fabric.
[0017] Furthermore, the textile is selected from knitted fabrics, woven fabrics, nonwoven fabrics, spray-bonded cotton, or polyester.
[0018] Furthermore, after the phase change aerogel composition is sprayed, impregnated, or brushed onto the surface of the textile, it needs to be treated at 100℃-160℃ for 1-10 minutes to obtain the phase change aerogel textile.
[0019] Furthermore, the temperature adjustment range of the phase change aerogel textile is 20-80℃.
[0020] Furthermore, the premixing is carried out using a premixing and dispersing device, in which the phase change aerogel and the binder are stirred for 0.5-2 hours to uniformly disperse the phase change aerogel in the binder to obtain a phase change aerogel emulsion.
[0021] The centrifugal separation process uses a centrifuge with a 50-500 mesh filter to centrifuge and filter the phase change aerogel emulsion, thereby separating the insoluble substances in the phase change aerogel emulsion from the emulsion.
[0022] In summary, the present invention has the following beneficial effects:
[0023] 1. This application uses phase change materials and aerogel materials to treat textiles, so that the textiles have both the heat insulation function of aerogel materials and the temperature regulation function of phase change materials. While retaining the rich pore structure of aerogel, the phase change materials are fixed and uniformly distributed.
[0024] 2. The method described in this application for preparing phase change aerogel textiles is simple, and the phase change function is stable and adjustable. Using the JIS L 1096A method, the thermal insulation rate is 74.5-82%, which is 2.5-10% higher than that of unprocessed products of the same weight. The clo value is 1.85-3.10, which is 0.23-1.48 higher than that of unprocessed products of the same weight. Temperature change tests show that the thermal insulation is 3℃-8℃ higher than that of unprocessed products of the same weight. Thermal buffering performance is less affected by temperature changes and exhibits smoother fluctuations. Temperature regulation performance shows that the temperature regulation difference between 40℃ and 15℃ reaches a maximum of +10℃, and the temperature regulation difference between 15℃ and 40℃ reaches a maximum of -10℃, demonstrating a significant temperature regulation effect.

[0069] Performance testing
[0070] 1. To demonstrate the influence of aerogel and aerogel pore size on the thermal insulation performance of the spray-bonded cotton, the thermal insulation rate and Clo value of the phase change aerogel spray-bonded cotton provided in Examples 1-8 above were tested using the JIS L1096A method and ASTM test. The test results are shown in Table 2.
[0071] Table 2
[0072]
[0073] As shown in Table 2, the phase change aerogel spray-bonded cotton prepared using the method of Example 1 has a 6% higher insulation rate and a 0.94 higher Clo value compared to the unprocessed product of the same weight; the phase change aerogel spray-bonded cotton prepared using the method of Example 2 has a 4% higher insulation rate and a 0.52 higher Clo value compared to the unprocessed product of the same weight; the phase change aerogel spray-bonded cotton prepared using the method of Example 3 has a 5% higher insulation rate and a 0.76 higher Clo value compared to the unprocessed product of the same weight; and the phase change aerogel spray-bonded cotton prepared using the method of Example 4 has a 7% higher insulation rate and a 1.36 higher Clo value compared to the unprocessed product of the same weight. It can be seen that the treated spray-bonded cotton has a higher insulation rate and Clo value than the unprocessed product. The aerogel treated with surfactants has a larger pore size, and the greater amount of air trapped inside the pores can better isolate airflow, thus significantly improving the insulation effect.
[0074] 2. Temperature change experiments were conducted on the phase change aerogel spray-bonded cotton provided in Examples 1-8:
[0075] Test method: A spacer was placed on the heat-receiving element, and the test piece was placed on top of it. An artificial sun lamp was used for illumination. The temperature of the heat-receiving element was measured before irradiation (T1) and 30 minutes after irradiation (T2), and the temperature rise (ΔT) was calculated. The test results are shown in Table 3. The test pieces were selected from phase change aerogel spray-bonded cotton treated according to the methods in Examples 1-8.
[0076] ΔT=T2-T1
[0077] Insulation temperature (ΔT') = ΔT 未加工品的喷胶棉 -ΔT 相变气凝胶喷胶棉
[0078] Table 3
[0079]
[0080] As can be seen from Table 3, after 30 minutes of irradiation, the temperature rise of the treated sprayed cotton was lower than that of the untreated sprayed cotton. The treated sprayed cotton was more heat-insulating than the untreated cotton. The aerogel treated with surfactants had larger pore sizes, and the more air was retained in the pores, which could better isolate air flow and significantly improve the heat insulation performance.
[0081] A blank experiment (without experimental pieces) was conducted using the above method, with untreated spray-bonded cotton as the experimental piece. The data were then compiled in conjunction with those from Examples 1 and 4. Figure 1 ,from Figure 1 It can be seen that the temperature of the heat-receiving body covered by phase change aerogel rises more slowly, proving that the pore size of the aerogel treated with surfactant is larger and more air is retained in the pores, which can better isolate air flow and significantly improve the heat insulation performance.
[0082] 3. Thermal buffering tests were conducted on the phase change aerogel spray-bonded cotton provided in Examples 1-8:
[0083] Test method:
[0084] 3.1 The temperature sensor was placed on a stainless steel plate and placed in an experimental environment (35℃±2) for more than 12 hours. The temperature environment was set to change from 35℃ to 5℃, starting with a decrease of 20℃ per hour until it reached 5℃ and held for 1 hour. Then, the temperature was increased from 5℃ to 35℃ at a rate of 20℃ per hour and held for 2 hours. The temperature of the stainless steel plate was measured, and the test results are shown in Table 4.
[0085] Table 4
[0086] time 0(min) 60 (min) 120 (min) 180 (min) 240 (min) 300 (min) Example 1 35.1 21.7 9.6 20.6 32.4 34.5 Example 2 35.1 23.6 11.5 18.7 30.5 32.6 Example 3 35.1 22.8 10.7 19.5 31.3 33.4 Example 4 35.1 24.5 12.4 17.8 29.6 32.0 Example 5 35.1 21.5 9.4 20.8 32.6 34.7 Example 6 35.1 21.1 9.0 21.2 33.0 34.9 Example 7 35.1 23.5 11.4 18.8 30.6 32.7 Example 8 35.1 23.2 11.0 19.0 30.9 33.0
[0087] As can be seen from Table 4, when the ambient temperature decreases, the phase change material can release energy to slow down the temperature decrease, and when the ambient temperature increases, the phase change material can store energy to slow down the temperature increase.
[0088] A blank experiment (without experimental pieces) was conducted using the above method, with untreated spray-bonded cotton as the experimental piece. The data were then compiled in conjunction with those from Examples 1 and 4. Figure 2 ,from Figure 2 It can be seen that increasing the amount of phase change material added can store more energy and is less affected by changes in ambient temperature.
[0089] 3.2 In the experimental environment (5℃±2), the stainless steel plate was placed for more than 12 hours. The ambient temperature was set to increase by 20℃ per hour from 5℃ to 35℃ and held for 1 hour. Then, the temperature was decreased from 35℃ to 5℃ at a rate of 20℃ per hour and held for 2 hours. The temperature of the stainless steel plate was measured. The test results are shown in Table 5.
[0090] Table 5
[0091] time 0(min) 60 (min) 120 (min) 180 (min) 240 (min) 300 (min) Example 1 5.6 19.7 32 20.5 9.1 6.4 Example 2 5.6 18.1 30.4 22.1 10.7 8 Example 3 5.6 18.6 30.9 21.6 10.2 7.5 Example 4 5.6 16.9 29.2 23.3 11.9 9.2 Example 5 5.6 19.9 32.2 20.3 8.9 6.2 Example 6 5.6 20.3 32.6 19.9 8.5 5.9 Example 7 5.6 18.2 30.5 22.0 10.6 7.9 Example 8 5.6 18.4 30.8 21.6 10.3 7.7
[0092] As can be seen from Table 5, when the ambient temperature rises, the phase change material can store energy and slow down the temperature rise; when the ambient temperature decreases, the phase change material can release energy and slow down the temperature decrease.
[0093] A blank experiment (without experimental pieces) was conducted using the above method, with untreated spray-bonded cotton as the experimental piece. The data were then compiled in conjunction with those from Examples 1 and 4. Figure 3 ,from Figure 3 It can be seen that increasing the amount of phase change material added can store more energy and is less affected by changes in ambient temperature.
[0094] Combination Figure 2 and Figure 3It can be seen that, compared with unprocessed products of the same weight, phase change aerogel spray cotton has a slower temperature drop when cooling (higher temperature) and a slower temperature rise when heating (lower temperature). Phase change aerogel spray cotton is less affected by temperature changes and has a smoother fluctuation.
[0095] 4. Temperature regulation test was conducted on the phase change aerogel spray cotton provided in Examples 1-7:
[0096] Test Method: Three 10*10cm test pieces were stacked together to form a test sheet. The test sheet was placed on the heat-insulating material, with a thermocouple temperature sensor placed between the top and bottom edges. The test sheet was placed in an environment of 40℃ for more than 4 hours, and then transferred to an environment of 15℃. The temperature change over time was measured. Alternatively, the test sheet was placed in an environment of 15℃ first, and then transferred to an environment of 40℃, and the same method was used. Measurement Environment: Temperatures of 40±2℃ and 15±2℃. The test results are shown in Table 6.

[0101] A blank experiment (without experimental pieces) was conducted using the above method, with untreated spray-bonded cotton as the experimental piece. The data were then compiled in conjunction with those from Examples 1 and 4. Figure 4 .
[0102] Combining Tables 6 and 7 and Figure 4 It can be seen that the phase change aerogel spray cotton treated with surfactants and with a higher amount of phase change material has a higher temperature difference and better temperature regulation performance.
[0103] 5. Scanning electron microscopy was performed on aerogel A and hydrophilic silica aerogel prepared in Example 1. The test results are shown in [reference needed]. Figure 5 .
[0104] Figure 5 (a) is a scanning electron microscope image of the untreated surfactant;
[0105] Figure 5 (b) is a scanning electron microscope image of aerogel A treated with surfactant;
[0106] from Figure 5 It can be seen that the pore size of the aerogel treated with surfactants increases, and the chlorosulfonic acid groups (ClSO) in the surfactants increase. 3-The surfactant undergoes an esterification reaction with the hydroxyl (OH) groups on the aerogel surface to generate hydrophilic groups, while the surfactant dissolves in acid to generate sulfate groups (SO₄). 3- The surfactant reacts with the hydroxyl groups within the silica aerogel to form sulfate bonds. This cross-linking reaction increases the strength, stability, and durability of the aerogel. The surfactant undergoes hydrolysis during dissolution in acid, releasing chloride and sulfate ions. These ions further participate in the internal structure of the aerogel, modifying it and increasing its pore size. However, acid alone cannot simultaneously provide chlorosulfonic acid groups (ClSO₄²⁻). 3- ) and sulfate groups (SO 3- This method cannot achieve the purpose of synergistic modification of aerogels.
[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
