Description

Shoe insole and its manufacturing method {OUTSOLE IN FOOTWEAR AND METHOD FOR MANUFACTURING THEREOF}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe insole and a method of manufacturing the same, and more particularly, to a shoe insole that promotes blood circulation by foot pressure, removes foot odor, removes bacteria, and improves breathability.

Generally, the insole is placed on the inner floor such as shoes, sneakers, etc. (hereinafter referred to as 'shoes') to prevent cushioning while improving cushioning and comfort.

In recent years, height insoles have been released to increase height, and foot, which is a miniature version of the human body, has been able to selectively use items having efficacy such as acupressure, deodorization, and antibacterial in keeping with the trend of pursuing well-being.

The foot is not only composed of many bones, joints, ligaments, muscles and blood vessels, but also concentrated in acupuncture points and meridians. The foot is called a microcosm of the human body because it is connected to all other organs of the body by all distributed acupuncture points. Efforts to activate the metabolism and function of related organs by stimulating these acupuncture points on the foot have been made since ancient times, centering on oriental medicine, and the fruits of this have been transmitted to modern medicine. Therefore, the foot acupressure method which tries to maintain the health of a body by promoting the function of the related human organs by stimulating the reflector (acupuncture point) distributed in a foot with acupressure, acupuncture, massage, etc. is widely popular.

In addition, since the part of the sole of the person is generally concave between the heel and the heel, there is a problem that the concave portion cannot be stimulated while standing or walking. In particular, because the concave part of the sole has a number of acupoints that affect the internal organs such as the kidneys, stomach, pancreas and duodenum, the acupressure of this part is also important.

These important feet in the human body are exposed to the outside when the weather starts to cool and dry, and the friction and pressure are so severe that they become dry and loose due to the irritation of the sole of the foot due to walking and lack of moisture. It may be caused by deformation of the foot, inadequate shoes or occupational effects, overweight, aging of the skin, lack of nutrition, or genital abnormalities. In severe cases, the heel splits, changes in the season or winter, bleeding and pain, and severe cracks can be a secondary bacterial infection as a crack.

These and other objects and novel features of the present invention will become more apparent from the description of the present specification and the accompanying drawings.

First, the composition of the shoe insole according to the present invention will be described.

The composition of the shoe insole according to the present invention is a composition added with antibacterial, deodorant, and far infrared rays harmless to the human body, polyurethane resin, silicone resin, vinyl chloride resin, polyethylene, polypropylene, polystyrene, polyester and / or mixtures thereof The raw material selected from the group consisting of in the clay or ocher, silver nanoparticles, including charcoal as an additive composition.

The composition of the shoe insole according to the present invention contains 75-85 parts by weight, preferably 80 parts by weight, as the ratio of the raw material to the total weight of the shoe insole composition (hereinafter simply referred to as "parts by weight").

If the raw material is less than 75 parts by weight, relatively expensive additives are contained in a large amount to increase the manufacturing cost, there is a fear that the bonding strength of the resin may be lowered, if exceeding 85 parts by weight there is a problem that the function of the additive is reduced.

Moreover, it is preferable to use polyurethane as a raw material. In the polyurethane, an alcohol having an active hydroxyl group (-OH) and an isocyanate group having an isocyanate group form a urethane bond by an addition polymerization reaction.

In addition, the composition of the shoe insole according to the present invention contains 8-12 parts by weight, preferably 10 parts by weight of clay. If the clay is less than 8 parts by weight, the far-infrared radiation effect is low, and if it exceeds 12 parts by weight, the bonding force is lowered. The white clay is a natural mineral, 20 times better than yellow soil, that is, it generates far-infrared rays, activates the physiology of cells, generates heat energy, and releases harmful substances. It has the effect of promoting metabolism and preventing aging, and has been widely used as a cosmetic and food additive for a long time.

In addition, the efficacy of commonly known clay is as follows.

White clay produces large amounts of negative ions and clears the air. Negative ions keep the room clean and fresh by curing, sedimenting and removing cations contained in various harmful substances around us. Thus, the nose and throat of those who were not bronchial are refreshed. The white soil absorbs all the smells of cigarettes, foods, and scents, so you don't need a fragrance.

Also, clay makes the head clear and cool by the generation of oxygen. Lack of ventilation can lead to heavy head and headaches. White clay makes ozone harmful to human body by making anion oxygen (O ₂ ) which is beneficial to human body, and solves the oxygen deficiency phenomenon in the room.

Also, the clay makes the body light by far-infrared radiation. In other words, white clay itself activates cellular functions by radiating far-infrared rays to help expand microvascular artery veins, promote systemic circulation, relieve stress, and sleep better. If the body's circulation is not working properly, toxins accumulate and become a disease. Toxin purification occurs during sleep, and after sleeping, the body becomes lighter.

Also, the clay does not generate static electricity, so the inside of the shoe is clean. Static electricity does not occur under the influence of negative ions, and fine dust in shoes does not stick to socks, clothes, etc., and is clean.

As a composition of the shoe insole of the present invention, loess may be applied instead of the clay.

That is, it may contain 8-12 parts by weight of ocher.

Ocher is a honeycomb structure with a wide surface, and a large number of spaces have a multi-layer structure. In this sponge-like hole, far infrared rays are absorbed and stored. They radiate when heated to stimulate molecular activity of other objects.

A spoonful of ocher contains 200 million microorganisms, and is filled with an active enzyme called caritase, a physiologically active substance beneficial to the human body that reduces, degrades and detoxifies the active oxygen peroxide that causes aging.

Moreover, in this invention, silver nanoparticles are mixed and it has antibacterial and deodorizing function.

That is, since the shoe insole of the present invention includes an aqueous silver-containing solution containing nano-sized silver, it has an antibacterial and antifouling performance that gives excellent antimicrobial, corrosion resistance and adhesion.

The silver nanoparticles have a strong antibacterial action by silver metal ions (Ag +), which are antimicrobial agents. Therefore, silver metal ions (Ag +) directly bind to bacteria -SH group, -COOH group, -OH group, etc. Oxygen is converted into active oxygen which sterilizes by destruction or disturbance, or catalyzed by silver, and antibacterial function is exerted by the sterilization mechanism by active oxygen.

On the other hand, as a method for refining silver to a nano size, an adsorption method for refining silver using an adsorption surfactant from a silver salt and a composite method for producing a polymer-silver nanocomposite using a silver salt and other polymers are generally used.

That is, in the adsorption method, when silver ions in the silver salt are reduced to silver nanoparticles, the size and distribution of the metal particles are controlled by the surfactant. When preparing silver nanoparticles using silver salt, an aqueous solution of surfactant is added, and due to the inherent nature of the surfactant to be adsorbed, silver (Ag) Fusion between particle nuclei is prevented. Therefore, the reduced metal particles are delayed or blocked from binding to other metal particle nucleus surfaces, thereby producing metal particles with uniform size distribution and fine particles. In the adsorption method, silver salts and surfactants such as AgNO ₃ are used, and metal ion reducing agents such as hydrazine, lithium aluminum borohydride, sodium borohydride and ethylene oxide are also added. The method for producing fine silver particles by the adsorption method is described in detail in Korean Patent Registration 375525.

The composition of the shoe insole according to the present invention contains 2-5 parts by weight, preferably 3 parts by weight of silver nanoparticles. Silver nanoparticles are not desirable if the diameter of the silver is less than 1.0nm due to the increase in cost by the production of nano silver, and if it exceeds 20nm, the nano silver is not uniformly dispersed when added to the resin does not exhibit sufficient antimicrobial effect, poor with resin Due to the mixed properties, poor adhesiveness and corrosion resistance are exhibited, which causes cost increase.

In addition, when the concentration of silver in the silver-containing solution is less than 2 parts by weight, a large amount of silver-containing solution should be used to maintain the concentration of silver relative to the resin when preparing the composition of the shoe insole, which results in impaired resin properties and reduced corrosion resistance and conductivity. do. If the silver concentration exceeds 5 parts by weight, it is not preferable because a large amount of stabilizer is required in order for the nanonized silver to be stabilized without reaction or entanglement.

Moreover, the raw material of the shoe insole of this invention contains 6-10 weight part of charcoal, for example, 7 weight part preferably. If the charcoal is less than 6 parts by weight, the original function of the charcoal is lowered. If it exceeds 10 parts by weight, the bonding strength of the resin is lowered.

Charcoal is a hard carbon activated carbon that is generally carbonized at a temperature of 1000 ℃ or higher. Although it varies slightly depending on the material of the wood used, there are numerous micropores of about 1 / 1000mm. ^It is a cube wide enough to ^two . These micropores have already been identified for their ability to adsorb and remove harmful substances and odor-causing components in water and are used for water purification, food filtration, alcohol purification, deodorization / dehumidification, and electromagnetic shielding.

In particular, 1 g of bamboo activated carbon has about two to three times more micropores than currently used palm, oak, and pine activated carbon, and also contains an active silicic acid, which exhibits excellent deodorizing function compared to other activated carbons.
