Functional insole and production process thereof

Abstract

The invention relates to a functional insole and a production process thereof. The functional insole comprises an insole surface layer, a polyurethane layer and a gluing layer, wherein the insole surface layer is in contact with the sole of a human body, the polyurethane layer is arranged on a shoe, and the gluing layer is used for combining the insole surface layer and the polyurethane layer together. The gluing layer consists of environment-friendly white glue with gluing function and functional powder with various functions. The glue coating comprises the following components in percentage:80 to 90 percent of white glue and 10 to 20 percent of functional powder. The functional powder consists of the following target components in percentage by weight: 21 to 33 percent of magnetic powder, 29 to 42 percent of negative ion powder, 26 to 44 percent of far infrared ceramic powder, 3 to 9 percent of jade powder and 4 to 11 percent of antibacterial powder. The functional insole can dilatecapillary vessels, enhance blood circulation and promote metabolism for a circulatory system; the functional insole can activate cells, excrete or endow regeneration ability to aged and dead cells, and enhance functions and vitality of cells for cell tissues.

Description

technical field [0001] The invention relates to the technical field of footwear, and relates to a functional insole, in particular to a functional insole and a production process thereof. Background technique [0002] Existing insoles generally have two structures: one is simply made of EVA material, and the other is simply made of elastic and wear-resistant elastomer material, including PU, SEBS, SBS, latex, rubber or other elastomers. Materials; Among them, the insole made of pure EVA material is light in weight and low in cost, but due to the lack of performance characteristics of the material itself, after wearing it for a period of time, the position of the force point of the heel and forefoot with relatively large force will be lost. Elasticity, forming pits, not having the function of shockproof, and the service life is relatively short; the insoles made of pure PU, SEBS, SBS, latex, rubber or other elastomer materials have good elasticity, wear resistance, comfort, e...

[0002] Existing insoles generally have two structures: one is simply made of EVA material, and the other is simply made of elastic and wear-resistant elastomer material, including PU, SEBS, SBS, latex, rubber or other elastomers. Materials; Among them, the insole made of pure EVA material is light in weight and low in cost, but due to the lack of performance characteristics of the material itself, after wearing it for a period of time, the position of the force point of the heel and forefoot with relatively large force will be lost. Elasticity, forming pits, not having the function of shockproof, and the service life is relatively short; the insoles made of pure PU, SEBS, SBS, latex, rubber or other elastomer materials have good elasticity, wear resistance, comfort, etc. Advantages, but there are shortcomings such as heavy product weight and expensive price

[0003] Chinese Invention Patent No. 201810083214.8 discloses "a multi-functional insole", which includes a wear-resistant layer. The inside of the wear-resistant layer is provided with cooling holes. The top of the wear-resistant layer is provided with a shockproof layer. The top of the battery is provided with a positive pole of the power supply and a negative pole of the power supply. The top of the battery is connected with a graphene heating layer through the positive pole of the power supply and the negative pole of the power supply. A graphene heating plate is arranged in the middle of the graphene heating layer. Graphene is a material with high resistance. According to Joule According to the law, when a certain current passes through, a heat that changes according to the current will be generated, and then heat will be provided for the insole. In winter, the insole will provide comfortable heat to the user's sole after wearing shoes, and graphene will generate heat. The plate will always generate heat to achieve heat preservation; however, it needs to install a battery in the insole, which will inevitably lead to an increase in the size of the insole, and there will be problems with the need to replace the battery or charge the point, which is not conducive to the promotion of the product
