Polyurethane functional insole

Abstract

Provided is a polyurethane functional insole. The insole comprises an artificial leather layer, an adhesive layer and a polyurethane layer, and the polyurethane layer and the artificial leather layerare bonded together by the adhesive layer; the adhesive layer is composed of a polyurethane glue and functional powder, the percentage of the polyurethane glue is 75%, and the percentage of the functional powder is 25%; the functional powder is composed of 12% of tourmaline, 10% of magnet, 10% of jade, 12% of ceramic composite powder, 6% of a bamboo charcoal, 6% of crystal, 20% of talc and 24% ofantibacterial powder with a particle size of less than 7000 mesh; the insole can be used for relieving pain and removing swelling and inflammation, has a good effect on rheumatism, vascular embolization inflammation, beriber, tinea pedis, helosis, heel pain and the like, and effectively massage the meridians and acupoints of the soles of the feet, and long-term use can promote blood circulation, settle five organs, help nerves, enhance brains, enhance memory, enhance physical fitness and prolong life.

Description

technical field [0001] The invention relates to the technical field of footwear, in particular to an insole, in particular to a functional polyurethane insole. 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, etc. Advantages, but there a...

[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] China Invention Patent No. 201710864215.1 discloses "a latex PU insole"; although it discloses a latex PU insole, including a bottom layer, a middle layer and a surface layer, the bottom layer is latex and combined with the middle layer heat treatment, and the temperature of the heat treatment combination is 150-180 The temperature and time are 50-200 seconds, the middle layer is PU, the surface of the middle layer is coated with glue and bonded with the surface layer, and the surface layer is cloth; among them, the ratio of latex in percentage is as follows: natural latex is 92-94%, Accelerator is 0.1%, dispersant is 0.1%, ammonia powder is 0.2%, swelling soil is 0.1%, and sulfur is the balance; but it needs two layers of glue to bond three layers of different substances together, and the process is relatively Complicated; although such insoles are relatively comfortable, they lack physiotherapy functions and cannot meet the increasing health care needs of modern people; and the natural latex of latex PU insoles is 92-94%, and the cost of natural latex is relatively high, which will lead to high product sales prices , is not conducive to the promotion of products
