Abstract
Description
A heat storage and heat preservation finishing liquid and its preparation method and application Technical Field
[0001] The present invention relates to a thermal insulation technology for textile fabrics, and in particular to a heat storage and thermal insulation finishing liquid, a preparation method thereof, and an application thereof. Background Art
[0002] With the development of modern science and technology, high-tech products are flooding the market, and people are also seeking more technologically advanced clothing products. The thermal insulation function of down jackets is no longer limited to relying solely on down to achieve the thermal insulation effect. Instead, more raw materials with far-infrared heating, light-absorbing heating, and other functions are used to prepare thermal insulation fabrics. Combined with down filling, multiple thermal insulation effects are achieved, thus satisfying people's pursuit of warmth, lightness, and fashion. Currently, the most commonly used heating materials in the industry include graphene, nanoceramics, and rare earths. Most of them are single components acting on the fabric, with limited thermal storage and heating effects. At the same time, the thermal insulation effect of down jackets on the market that use far-infrared insulation is between 1.5℃ and 2.5℃, and the thermal storage and insulation effect is also limited, far from meeting people's needs.
[0003] Summary of the Invention
[0004] Purpose of the invention: The purpose of the present invention is to improve the heat storage and thermal insulation effects of down jackets, provide a heat storage and thermal insulation finishing liquid, and provide a preparation method of this finishing liquid and the application of the finishing liquid in the preparation of down jacket fabrics.
[0005] Technical solution: The heat storage and heat preservation finishing liquid of the present invention includes 10%-15% silicon boron polymer, 3%-5% nano-ceramic material, 6%-15% acidic hot lava material, 1%-5% polysiloxane crosslinker, 5%-10% dispersant, 3%-5% binder, and the rest is water; the dispersant is fatty alcohol polyoxyethylene ether, fatty acid polyoxyethylene ester, naphthalene sulfonate and polycarboxylic acid, and the ratio is 3:1:2:1.
[0006] Furthermore, the silicon boron polymer is a nanomaterial with a diameter of 200nm-500nm.
[0007] Furthermore, the nano-ceramic material is at least one of kaolin, calcium carbonate, calcium borate, aluminum oxide, iron oxide and manganese oxide, and the ratio thereof is 1:1:2:3:1:1.
[0008] Furthermore, the acidic hot lava material is aluminosilicate, with a content of 56%-65% and a density of 0.4g / cm 3 -1.5g / cm 3 .
[0009] Furthermore, the adhesive is at least one of polyurethane, polyvinyl acetate, polyacrylate and butadiene, and the ratio thereof is 1:2:2:1.
[0010] Furthermore, the preparation method of the heat storage and heat preservation finishing liquid comprises the following steps:
[0011] (a) Mix and stir the raw materials uniformly for later use;
[0012] (b) adding zirconium beads to the mixed solution prepared in step (a) and grinding the mixed solution. The boric acid polymer, the nano-ceramic material, and the acidic hot lava material are uniformly mixed by the grinding under the action of the cross-linking agent, the dispersant, and the binder. The three components interact with each other and complement each other, thereby synergistically achieving the heat storage, heating, and heat preservation functions of the fabric by absorbing solar energy and reflecting thermal radiation.
[0013] (c) During the grinding process, an appropriate amount of water is added until the particle size of the mixed solution is uniform. The grinding machine speed is 10000 rpm-12000 rpm, and the grinding time is 45 min-90 min to obtain a high-efficiency heat storage and heat preservation finishing liquid.
[0014] Furthermore, in step (b), the particle size of the zirconium beads is 1.2 mm to 1.6 mm, and the mass of the zirconium beads is 3 to 4 times the mass of the mixed solution, so as to ensure that the particle size of the finishing solution is maintained at 300 nm to 500 nm.
[0015] Furthermore, the heat storage and heat preservation finishing liquid is applied to the treated ordinary nylon spunlace fabric by rotary screen printing to produce a fabric having both heat storage, heating and heat preservation functions.
[0016] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: 1. The particle size of the heat storage and thermal insulation finishing liquid is about 300nm-500nm, and it has no sedimentation after being placed for 12 months, good viscosity, a viscosity change rate of less than 5%, and good stability; 2. The three components of boric acid polymer, nano-ceramic material and acidic hot lava material interact with each other to achieve the heat storage and thermal insulation functions of the fabric by absorbing solar energy and reflecting thermal radiation. The heat storage and thermal insulation can be increased by more than 20°C within 20 minutes, and the far-infrared reflectivity is more than 98%; 3. The heat storage and thermal insulation durability is good, and after being washed 10 times, it still has good heat storage and thermal insulation performance and high far-infrared reflectivity, and the change rate of both is less than 5%; 4. The use of rotary screen printing on the fabric increases the content of the heat storage and thermal insulation finishing liquid in the fabric, and the heat storage and thermal insulation performance is better. DETAILED DESCRIPTION
[0017] The technical solution of the present invention is further described below.
[0018] Example 1
[0019] A heat storage and heat preservation finishing liquid comprises 13% borosilicate polymer, 4% nano-ceramic material, 10% acidic hot lava material, 3% polysiloxane crosslinking agent, 8% dispersant, 4% binder, and the remainder is water; the borosilicate polymer is a nano-material with a diameter of 200nm-500nm; the nano-ceramic material is kaolin, calcium carbonate, calcium borate, aluminum oxide, iron oxide, and manganese oxide in a ratio of 1:1:2:3:1:1; the acidic hot lava material is aluminosilicate with a content of 56%-65% and a density of 0.4g / cm 3 -1.5g / cm 3 The dispersants are fatty alcohol polyoxyethylene ether, fatty acid polyoxyethylene ester, naphthalene sulfonate and polycarboxylic acid, and the ratio is 3:1:2:1; the adhesives are polyurethane, polyvinyl acetate, polyacrylate and butadiene, and the ratio is 1:2:2:1.
[0020] The preparation method of the heat storage and heat preservation finishing liquid comprises the following steps:
[0021] (a) mixing the raw materials in the above mass percentages and stirring them uniformly for later use;
[0022] (b) adding the mixed solution prepared in step (a) to a vertical mill and adding zirconium beads for grinding, wherein the particle size of the zirconium beads is 1.2 mm to 1.6 mm, and the mass of the zirconium beads is 4 times the mass of the mixed solution;
[0023] (c) During the grinding process, an appropriate amount of water is added until the particle size of the mixed solution is uniform. The grinding machine speed is 10000 rpm-12000 rpm, and the grinding time is 45 min-90 min to obtain a high-efficiency heat storage and heat preservation finishing liquid.
[0024] The prepared thermal storage and insulation finishing liquid had a particle size of 300-500 nm and was then left for a period of time to test its performance. As shown in Table 1, after 12 months, the components of the finishing liquid remained stably mixed, with no sedimentation. The viscosity was approximately 2.38 mPa·s, with a viscosity change of 3.03%. Thorough grinding ensured the small particle size and good uniformity of the thermal storage and insulation finishing liquid. Furthermore, the crosslinker, dispersant, and binder ensured that the boric acid polymer, nanoceramic material, and acidic hot lava material were uniformly dispersed in the solution, resulting in good dispersion and low viscosity change, ensuring excellent stability of the finishing liquid.

[0026] The prepared heat-storage and heat-insulating finishing liquid was applied to down jacket fabrics. Rotary screen printing was applied to treated, ordinary nylon spunlace fabric to create a fabric that simultaneously stores heat and maintains heat. The boric acid polymer, nanoceramic material, and acidic hot lava material interact and complement each other, synergistically absorbing solar energy and reflecting thermal radiation to achieve both heat storage and heat preservation.

[0029] As shown in Table 2, the fabric stored heat and heated up by more than 20°C within 20 minutes. After being washed 10 times, the fabric stored heat and heated up by 19.8°C within 20 minutes, with the heat storage and heating performance decreasing by less than 5%, indicating that the fabric has a good heat storage and heating effect. As shown in Table 3, the fabric has a reflectivity of more than 98% for far-infrared heat energy. After being washed five times, the reflectivity remained above 98%. After being washed 10 times, the reflectivity was 96%, a decrease of only about 2%. The fabric still maintained a stable and efficient thermal insulation effect.
[0030] Example 2
[0031] A heat storage and heat preservation finishing liquid comprises 10% borosilicate polymer, 5% nano-ceramic material, 15% acidic hot lava material, 5% polysiloxane crosslinker, 10% dispersant, 5% binder, and the remainder is water; the borosilicate polymer is a nano-material with a diameter of 200nm-500nm; the nano-ceramic material is kaolin; the acidic hot lava material is aluminosilicate with a content of 56%-65% and a density of 0.4g / cm 3 -1.5g / cm 3 ; The dispersant is fatty alcohol polyoxyethylene ether; the adhesive is polyurethane and polyvinyl acetate, the ratio of which is 1:2.
[0032] The preparation method for the thermal storage and insulation finishing liquid was the same as that of Example 1, except that the mass of the zirconium beads was three times that of the mixed solution. The particle size of the prepared thermal storage and insulation finishing liquid remained between 300 nm and 500 nm. As shown in Table 4, after 8 months, the components of the finishing liquid remained stably mixed and showed no sedimentation. The viscosity was approximately 3.76 mPa·s, with a viscosity change rate of 7.43%. After 12 months, the finishing liquid began to settle, reaching a viscosity of approximately 3.82 mPa·s, with a viscosity change rate of 9.14%. The thermal storage and insulation finishing liquid prepared using this formulation exhibited a relatively high viscosity, ranging from 3.5 mPa·s to 3.82 mPa·s, with a large viscosity change rate. After 12 months, sedimentation occurred, indicating poor stability.

[0034] The prepared heat-storage and heat-insulating finishing liquid was applied to fabric using the method of Example 1, resulting in a fabric with both heat-storage and heat-insulating properties. As shown in Table 5, the fabric achieved a heat-storage and heat-increasing performance of 16.8°C within 20 minutes, demonstrating poor heat-storage and heat-increasing performance. After 10 washes, the heat-storage and heat-increasing performance decreased by 10.12%. As shown in Table 6, the fabric's reflectivity to far-infrared heat energy was above 92%. This reflectivity remained above 92% after five washes, and after 10 washes, the reflectivity decreased by only approximately 2.17%. This finishing liquid exhibited poor heat-storage and heat-increasing performance, poor heat-storage and heat-increasing stability, and low reflectivity to far-infrared heat energy, but exhibited high reflectivity stability.

[0039] The preparation method for the thermal storage and heat preservation finishing liquid was the same as that of Example 1. The particle size of the prepared thermal storage and heat preservation finishing liquid remained between 300 nm and 500 nm. As shown in Table 7, after four months, the components of the finishing liquid remained stably mixed, with no sedimentation. The viscosity remained around 1.35 mPa·s, with a viscosity change rate of 3.05%. Starting at eight months, the finishing liquid began to settle, and the viscosity increased rapidly. After 12 months, the viscosity increased to around 1.45 mPa·s, with a viscosity change rate of 10.69%. The thermal storage and heat preservation finishing liquid prepared using this formulation had a relatively low viscosity of 1.31 mPa·s to 1.45 mPa·s, a large viscosity change rate, and after eight months, sedimentation occurred, indicating poor stability.

[0044] As shown in Table 8, this fabric achieved a 18.2°C thermal storage and temperature increase within 20 minutes, which is inferior to that of Example 1. However, after 10 washes, the thermal storage and temperature increase performance decreased by less than 2%, indicating good thermal storage and temperature stability. As shown in Table 9, the fabric's reflectivity to far-infrared heat energy was over 98%, remaining above 98% after five washes. After 10 washes, the reflectivity decreased by only approximately 2.04%. While this finishing solution's thermal storage and temperature increase performance was inferior to that of Example 1, the reflectivity and reflectivity stability of this finishing solution were not significantly different from those of Example 1.

[0081] Comparative Example 6
[0082] A heat storage and heat preservation finishing liquid, wherein the dispersant used is polyvinyl pyrrolidone, and the other components and proportions, preparation method and application in fabric preparation are the same as those in Example 1. The particle size of the prepared heat storage and heat preservation finishing liquid is maintained at 300nm-500nm.
[0083] As can be seen from Table 25, the viscosity of the finishing liquid ranged from 2.39 mPa·s to 2.98 mPa·s, showing a significant change in viscosity compared to Example 1.

The rate of change in viscosity and stability of the finishing liquid were close to those of Comparative Example 5, which were both relatively poor.
[0084] Table 25 Thermal storage and insulation finishing liquid stability test results
[0085] As can be seen from Tables 26-27, the fabric prepared with the finishing liquid stored heat and rose in temperature by 18.9°C within 20 minutes.

After being washed 10 times, the reflectivity dropped to 88%, and the reflectivity decreased by about 7.37%. The reflectivity to far-infrared heat energy was low, and the stability of the reflectivity to far-infrared heat energy was poor.
[0086] Table 26 Test results of thermal storage and heating performance of thermal insulation fabrics
[0087] Table 27 Thermal insulation performance test results of heat storage and thermal insulation fabrics
[0088] As shown in Table 28, the stability, thermal storage and temperature-raising performance, and insulation performance of the finishing solutions of Examples 1-3 and Comparative Examples 1-6 were compared. The finishing solution prepared in Example 1 exhibited moderate viscosity, low viscosity change, and the best stability. Fabrics prepared with this finishing solution exhibited a thermal storage and temperature-raising rate of less than 5% after 10 washes, and their far-infrared reflectivity decreased by approximately 2%. The main active ingredients in the finishing solution—boric acid polymer, nanoceramic material, and acidic hot lava material—have thermal storage and temperature-raising functions. The nanoceramic material also reflects thermal radiation. The three components, when ground and mixed in appropriate proportions, interact synergistically, absorbing solar energy and reflecting thermal radiation to achieve thermal storage and insulation for the fabric. The nanoscale active ingredients, under the action of the crosslinking agent, dispersant, and binder, are evenly dispersed in the solution. This excellent dispersion ensures that the finishing solution remains stable for extended periods, exhibits minimal viscosity change, and maintains excellent stability.
[0089] In Example 2, the high content of nano-ceramic material results in a small particle size, few surface defects, good adhesion to other components, and high strength. Simultaneously, the high content of cross-linking agent and the high total mass of the finishing liquid increase the viscosity of the finishing liquid. In Example 3, the cross-linking agent content is too low, resulting in weak interaction between the active components and low viscosity and poor stability of the finishing liquid.
[0090] Analyzing the performance of the finishing solutions of Comparative Examples 1-3, Comparative Example 1, which lacks a boric acid polymer, exhibits low thermal storage and temperature rise, and the worst stability, indicating that boric acid polymers have the greatest impact on the thermal storage and temperature rise performance of the fabric. Comparative Example 2, which lacks a nano-ceramic material, exhibits low far-infrared reflectivity, resulting in poor thermal insulation, indicating that nano-ceramic materials have the greatest impact on the far-infrared reflectivity of the fabric. Comparative Example 3, which lacks an acidic hot lava material, exhibits higher far-infrared reflectivity and better thermal insulation than Comparative Example 2, but after 10 washes, the thermal insulation effect decreases by 4.17%, and the thermal insulation stability is poor, indicating that the acidic hot lava material has the greatest impact on the thermal insulation stability of the fabric. Furthermore, the dispersant and binder components in Comparative Examples 1 and 2 are relatively simple, resulting in uneven dispersion of the effective components and poor stability of the finishing solution. After prolonged storage, the finishing solution exhibits severe sedimentation, a decrease in the effective components, and an increase in the viscosity of the finishing solution, which in turn affects its content in the fabric and its thermal storage and temperature rise performance. The lack of any of the three components will affect the dispersibility and stability of the finishing liquid, and thus affect its heat storage or insulation effect.
[0091] Table 28 Performance test results of heat storage and thermal insulation finishing liquids with different ratios and fabrics prepared therefrom
[0092] Comparative Examples 4-6, the finishing liquids were modified in the type and combination of the crosslinking agent, dispersant, and adhesive. In Comparative Examples 4 and 6, the type and amount of the dispersant were changed, while the crosslinking agent and adhesive remained unchanged. The finishing liquids prepared began to settle after four months of storage, indicating extremely poor dispersion stability. The finishing liquids also exhibited poor thermal storage and heating performance and low far-infrared reflectivity. After 10 washes, the thermal storage and heating performance decreased by 11.83%-14.81%, and the thermal insulation performance decreased by 5.32%-7.37%. The poor thermal storage and reflectivity stability indicates poor adhesion of the active ingredients to the fabric. In Comparative Example 5, the type and amount of the crosslinking agent, dispersant, and adhesive were modified, while the amount remained unchanged. The finishing liquid prepared exhibited sedimentation after eight months of storage, indicating poor dispersion stability and significant viscosity fluctuations. The finishing liquid also exhibited poor thermal storage and heating performance and low far-infrared reflectivity. After 10 washes, the thermal storage and heating performance decreased by 6.28%, and the thermal insulation performance decreased by 7.29%.
[0093] This demonstrates that different crosslinkers, dispersants, and binders, as well as their combinations, acting on the same proportions of heat-storing and heat-insulating components, can cause the finishing liquid to settle after different periods of time, with varying degrees of sedimentation. This results in significant variations in the finishing liquid's viscosity, dispersibility, and dispersion stability. The dispersant improves the finishing liquid's dispersibility and ensures uniform dispersion of the active components. The crosslinker and binder synergistically bind the active components, maintaining their stable dispersion and viscosity over time. This locks the active components within the finishing liquid, allowing more of them to be transferred to the fabric upon application, achieving a thermal storage and heat-insulating effect. Furthermore, the crosslinker, dispersant, and binder synergistically enhance the adhesion of the active components to the fabric surface, ensuring that the fabric maintains its excellent thermal storage and heat-insulating properties even after multiple washes.
