Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of insoles, in particular to a heat-insulating insole. Background Art
[0002] An insole is a gasket placed inside a shoe to provide additional comfort, support, and protection. As a transition between the foot and the sole, the insole needs to have certain functionality. Especially in cold winter, a pair of insoles with excellent thermal insulation properties can effectively increase the temperature inside the shoe.
[0003] In the prior art, traditional insoles are usually used to achieve warmth by using different thermal insulation materials so that the structures of different materials can trap as much air as possible to achieve a heat-insulating effect. However, stacking various material structures will sacrifice other properties of the insole to achieve better warmth retention, and usually there will be problems such as the insole being too thick, poor air permeability and elasticity, which need to be solved urgently. Utility Model Content
[0004] In view of the above-mentioned deficiencies in the prior art, the present application provides a heat-insulating insole.
[0005] The above invention objectives of the present application are achieved through the following technical solutions:
[0006] The insole body comprises a heat storage surface layer, a support layer and a heat insulation layer from top to bottom, the heat storage surface layer is made of wear-resistant fiber felt, the heat storage surface layer is coated with nano metal oxide with heat storage capacity, the support layer is made of nano microbead coating, and the heat insulation layer is made of aerogel coating.
[0007] By adopting the above technical scheme, wear-resistant fiber felt is used as the basic material, and a variety of nano-metal oxides with heat storage capacity are evenly coated on one side of the fiber felt by a coating method to form a heat storage surface layer, so that when the user's sole contacts the heat storage surface layer, the heat storage surface layer can quickly absorb and store heat, and continuously provide warmth to the sole of the foot through thermal feedback, forming a circulating insulation effect. Nano-bead coating is used as a supporting layer. The tiny pores between the nano-beads can promote air circulation, provide good air permeability, keep the feet dry and comfortable, and at the same time enhance the support of the insole and reduce foot pressure. The antibacterial properties of nanomaterials can be used to effectively inhibit bacterial growth and achieve antibacterial and deodorizing effects. Aerogel coating is used as an insulating layer. The low thermal conductivity of aerogel itself can significantly reduce the loss of heat through the sole and extend the insulation time. The above three-layer complementary structural design can reduce the thickness of the insole while improving its thermal insulation performance, thereby improving the practicality and comfort of the insole.
[0008] In a preferred example, the present application can be further configured as follows: the aerogel coating is prepared by mixing aerogel particles and an adhesive.
[0009] By adopting the above technical solution, aerogel particles and adhesive are mixed to form a uniform coating, which can play a heat-insulating role and be elastic at the same time, so as to improve the elasticity of the insole, thereby improving the comfort of the insole. At the same time, the coating formed by the mixture of aerogel particles and adhesive has a large number of micropores, which will generate adsorption force when it contacts the sole to avoid the curling of the insole, thereby further improving the comfort of the insole.
[0010] In a preferred example, the present application can be further configured as follows: the nano-bead coating is prepared by mixing nano-beads and an adhesive.
[0011] By adopting the above technical solution, the nano beads are mixed with the adhesive to form a uniform coating, so that the nano beads can be evenly distributed inside the insole to evenly support the foot and improve the wearing comfort.
[0012] In a preferred example, the present application can be further configured as follows: the heat storage surface layer, the support layer and the heat insulation layer are adhered and fixed by coating.
[0013] By adopting the above technical solution, the coating method can ensure uniform fitting between the heat storage surface layer, the support layer and the insulation layer, can be applicable to the fitting between different material layers, and can achieve a lightweight design of the insole, reduce the extra burden and weight, and improve wearing comfort.
[0014] In a preferred example, the present application can be further configured as follows: the thickness of the wear-resistant fiber felt used for the heat storage surface layer is 0.3-0.4 mm, the thickness of the nano-bead coating used for the support layer is 0.3-0.4 mm, the thickness of the aerogel coating used for the insulation layer is 0.5 mm-0.6 mm, and the superimposed thickness of the heat storage surface layer, the support layer and the insulation layer does not exceed 1.5 mm.
[0015] By adopting the above technical solution, after superimposing the heat storage surface layer, support layer and insulation layer in this thickness range, a complementary structural design can be completed, which can reduce the thickness of the insole while improving its thermal insulation performance, thereby improving the practicality and comfort of the insole.
[0016] In summary, the present application includes at least one of the following beneficial technical effects:
[0017] 1. Wear-resistant fiber felt is used as the basic material, and a variety of nano-metal oxides with heat storage capacity are evenly coated on one side of the fiber felt by a coating method to form a heat storage surface layer, so that when the user's sole touches it, the heat storage surface layer can quickly absorb and store heat, and continuously provide warmth to the sole of the foot through thermal feedback, forming a circulating insulation effect. Nano-bead coating is used as the supporting layer. The tiny pores between the nano-beads can promote air circulation, provide good air permeability, keep the feet dry and comfortable, and at the same time enhance the support of the insole and reduce foot pressure. The antibacterial properties of nanomaterials can be used to effectively inhibit bacterial growth and achieve antibacterial and deodorizing effects. Aerogel coating is used as the insulation layer. The low thermal conductivity of aerogel itself can significantly reduce the loss of heat through the sole and extend the insulation time. The above three-layer complementary structural design can reduce the thickness of the insole while improving its thermal insulation performance, thereby improving the practicality and comfort of the insole.
[0018] 2. The aerogel particles are mixed with the adhesive to form a uniform coating, which can play a role in heat insulation and is elastic at the same time, so as to improve the elasticity of the insole, thereby improving the comfort of the insole. At the same time, the coating formed by the mixture of aerogel particles and adhesive has a large number of micropores, which will generate adsorption force when it contacts the sole to avoid the curling of the insole, thereby further improving the comfort of the insole.
[0019] 3. The coating method can ensure uniform fitting between the heat storage surface layer, the support layer and the insulation layer. It can be applied to the fitting between different material layers, and can achieve lightweight design of the insole, reduce the extra burden and weight, and improve wearing comfort.

[0023] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.
[0024] It should be noted that the terms "first", "second", etc. in the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.
[0025] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.
[0026] A heat-insulating insole of the present application is described below with reference to the accompanying drawings.
[0027] like Figure 1 and Figure 2 As shown, the heat-insulating insole comprises an insole body 1, which comprises a heat storage surface layer 2, a support layer 3 and a heat insulation layer 4 from top to bottom. The heat storage surface layer 2 adopts a wear-resistant fiber felt 5, and the heat storage surface layer 2 is coated with a nano-metal oxide 6 with heat storage capacity. The support layer 3 is made of a nano-bead coating, and the heat insulation layer 4 is made of an aerogel coating. The wear-resistant fiber felt 5 is used as a basic material, and a plurality of nano-metal oxides 6 with heat storage capacity are evenly coated on one side of the fiber felt by a coating method to form a heat storage surface layer 2, so that when the user's sole contacts it, the heat storage surface layer 2 can quickly absorb heat and store heat, and continuously provide warmth to the sole of the foot through thermal feedback, forming a cycle In order to improve the thermal insulation effect, nano-bead coating is used as the supporting layer 3. The tiny pores between the nano-beads can promote air circulation, provide good breathability, keep the feet dry and comfortable, enhance the support of the insole, reduce the pressure on the feet, and use the antibacterial properties of nano-materials to effectively inhibit the growth of bacteria and achieve the antibacterial and deodorizing effect. Aerogel coating is used as the thermal insulation layer 4. The low thermal conductivity of aerogel itself can significantly reduce the loss of heat through the sole and extend the thermal insulation time. The above three-layer complementary structural design can reduce the thickness of the insole while improving its thermal insulation performance, thereby improving the practicality and comfort of the insole.
[0028] It should be noted that the wear-resistant fiber felt 5 is a felt-like material made of fiber material, which has high wear resistance and tensile strength. Using it as the basic material of the heat storage surface layer 2 can significantly improve the strength and wear resistance of the insole surface layer, and the nano metal oxide 6 with heat storage capacity is evenly coated on one side of the fiber felt by coating to form a heat storage surface layer 2 that can quickly absorb and store heat, and continuously provide warmth to the sole of the foot through thermal feedback, forming a circulating insulation effect. Among them, the nano metal oxide 6 with heat storage capacity can be selected from nano phase change materials. Nano phase change materials are materials that can undergo phase change (transition between liquid and solid) within a specific temperature range. These materials can absorb or release a large amount of heat during the phase change process to achieve storage and release of thermal energy. Common nano phase change materials include nano metal oxides 6 such as nano titanium dioxide and nano aluminum oxide.
[0029] Furthermore, the aerogel coating is prepared by mixing aerogel particles and an adhesive. The aerogel particles and the adhesive are mixed to form a uniform coating, which can have elasticity while playing a heat-insulating role, so as to improve the elasticity of the insole, thereby improving the comfort of the insole. At the same time, the coating formed by the mixture of aerogel particles and the adhesive has a large number of micropores, which will generate adsorption force when it contacts the sole to prevent the insole from curling, thereby further improving the comfort of the insole.
[0030] Furthermore, the nano-bead coating is prepared by mixing nano-beads and an adhesive, and the nano-beads and the adhesive are mixed to form a uniform coating, so that the nano-beads can be evenly distributed inside the insole to evenly support the foot and improve wearing comfort.
[0031] In addition, the heat storage surface layer 2, the support layer 3 and the insulation layer 4 are bonded and fixed by coating. By adopting the coating method, it can be ensured that the heat storage surface layer 2, the support layer 3 and the insulation layer 4 are bonded evenly, which can be applicable to the bonding between layers of different materials and can realize the lightweight design of the insole, reduce the extra burden and weight, and improve the wearing comfort.
[0032] In this embodiment, the thickness of the wear-resistant fiber felt 5 used in the heat storage surface layer 2 is 0.3-0.4 mm, the thickness of the nano-bead coating used in the support layer 3 is 0.3-0.4 mm, the thickness of the aerogel coating used in the insulation layer 4 is 0.5-0.6 mm, and the superimposed thickness of the heat storage surface layer 2, the support layer 3 and the insulation layer 4 does not exceed 1.5 mm. By superimposing the heat storage surface layer 2, the support layer 3 and the insulation layer 4 in this thickness range, a complementary structural design can be achieved, and the thickness of the insole can be reduced while improving its thermal insulation performance, thereby improving the practicality and comfort of the insole. In actual tests, after the heat storage surface layer 2 contacts the sole of the foot, it can absorb heat and store heat and rise by 6°C in a short time (with the sole temperature as a reference), and then heat the sole of the foot through thermal feedback to form a cycle.
[0033] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
