By manufacturing the insole using a composition consisting of a synthetic resin and various additives, it has excellent antibacterial and deodorizing performance, maintains resilience and resilience, and is environmentally friendly by the biodegradable effect of natural mixed resins. It's about insoles.

Recently, as the functional footwear market has been greatly activated, various kinds of functional shoes have been developed and released to satisfy various needs of consumers. Functionality of these shoes is most of the functional endowment to the sole of the shoe, insoles, midsoles and outsoles to give a variety of functionalities, in particular, the insoles in direct contact with the sole is very important and has been developed in various ways.

The functions of insoles developed in the meantime are mainly due to the improvement of physical properties such as resilience and resilience to alleviate the impact of the soles received from the ground by the weight of the human body when people wear shoes and relieve impact resistance by relieving impact resistance. It is related to insoles that provide antibacterial and deodorizing functions in shoes by containing silver nanoparticles or copper in a synthetic resin composition for reducing or or manufacturing insoles.

As mentioned above, insole is generally known to be harmless to the human body in the case of silver nanoparticles added as an ingredient to increase the antibacterial and deodorizing power. However, in recent years, silver is eluted or absorbed by the human body to be poisoned. Affects the graying of skin tissue. In recent years, the problem that the nanoscaled material is absorbed into the skin tissue and respiratory system by the use of the silver nanoparticle material has been frequently pointed out to cause harm to the human body. In addition, even in the case of copper particles, copper oxide, which emits blue color due to sweat generated from the soles of the feet, is known to be harmful to the human body.

By further strengthening antibacterial activity, the fresh scent makes the shoes more comfortable to wear due to the scent generated from insoles when the shoes are ignited, and it is eco-friendly due to the biodegradable effect of the natural mixed resin by mixing with the synthetic resin. It is an advantage.

The technical configuration of the present invention for achieving the above problems in detail as follows.

The present invention is 100 parts by weight of the base consisting of 10 to 15% by weight of natural mixed resin and 85 to 90% by weight of synthetic resin,

15 to 20 parts by weight of filler, 1 to 3 parts by weight of stearic acid, 2 to 6 parts by weight of zinc oxide, 0.5 to 3.0 parts by weight of crosslinking agent, 0.2 to 1.0 parts by weight of crosslinking aid, 3 to 10 parts by weight of foaming agent And it relates to an environmentally friendly antibacterial insole molded and pressed using a composition consisting of 0.5 to 5 parts by weight of pigment.

The present invention is an eco-friendly antimicrobial insole molded and compressed using a composition mixed with a synthetic resin having antibacterial and deodorizing performance, in particular, extracts of starch and wormwood are not powder but rosin, starch and lactide (lactide) and It is characterized by natural mixing resin by mixing.

In the present invention, the natural mixed resin composition consisting of 5 to 25 parts by weight of Eochocho extract, 20 to 25 parts by weight of wormwood extract, 20 to 25 parts by weight of rosin, starch 20 to 25 parts by weight and lactide (lactide) 15 to 20 parts by weight It is preferable to shape | mold using.

The Eochocho extract is used by extracting by heating 10 ~ 30 parts by weight of ethanol vinegar for 1 to 2 hours at a temperature of 70 ~ 75 ℃, ethanol 100 ethanol, the efficacy of Eochocho to have a strong antibacterial action as known by the synonym It is known, but because it has a slightly fishy smell, it cannot use a large amount, and it works to supplement the antibacterial and deodorizing power of wormwood.

In the present invention, the mixing amount of Echochocho extract is preferably 5 to 25 parts by weight, and when the amount of Echochocho extract is less than 5 parts by weight, the antibacterial and deodorizing performance may be degraded, and the amount of Echochocho extract is more than 25 parts by weight. If you do, the antibacterial and deodorant performance is improved, but there is a risk that a fishy smell occurs.

And in the present invention, the mugwort extract is put into 100 to 100 parts by weight of ethanol by the same method as the method of extracting the eoseongcho 10 to 30 parts by weight of the extract used by heating for 1-2 hours at a temperature of 70 ~ 75 ℃, mugwort Efficacy of the antibacterial and deodorizing effect, and when ignited to act as a wormwood in the insole to feel a pleasant texture.

In the present invention, it is preferable that the mixed amount of the mugwort extract is 20 to 25 parts by weight, and when the blended amount of the mugwort extract is less than 20 parts by weight, the antibacterial and deodorizing performance may be degraded, and the amount of the mugwort extract is 25 parts by weight. If exceeded, the performance of antibacterial and deodorizing performance is improved, but the excess of mugwort extract is mixed, and the physical properties of natural mixed resin decreases due to the excess water content during the manufacture of natural mixed resin. There is a possibility that the physical properties of the.

In addition, in the present invention, the extract and the mugwort extract of the Echochocho extract and the mugwort component may be insufficient when the extraction conditions are less than the above-defined range, and the extraction condition exceeds the above-defined range. In particular, the extraction amount of the fish vinegar component and the mugwort component are no longer remarkably extracted.

And in the present invention, the rosin acts to combine the mixture of Eochochocho extract, mugwort extract, starch and lactide (lactide), and improves the binding force of the natural mixed resin and synthetic resin thus prepared. In addition, the terepin contained in the rosin further strengthens the antibacterial activity by phytoncid, which is a main ingredient, and acts to make the sensation of comfort comfortable by the fragrance generated in the insole when the shoes are ignited by the fresh scent.

In the present invention, it is preferable that the mixing amount of the rosin is 20 to 25 parts by weight, and when the mixing amount of the rosin is less than 20 parts by weight, the components of the natural mixed resin may not be properly combined, and the mixing amount of the rosin may exceed 25 parts by weight. In this case, there is a concern that the function of the antimicrobial and deodorant performance may decrease as the amount of mixing of the herbal components having the antibacterial and deodorant performance decreases.

And in the present invention, the starch extract and mugwort extract is not directly combined with the rosin, first mixed with starch and then mixed with lactide (lactide) and then combines with the rosin.

It is preferable that the mixing amount of the said starch is 20-25 weight part. If the amount of starch is less than 20 parts by weight, there is a risk that the fishery extract and mugwort extract may not be properly accommodated in the natural mixed resin component. If the amount of starch is more than 25 parts by weight, the antibacterial and deodorizing properties may be relatively high. As the mixing amount of the herbal components decreases, there is a concern that the function of the antibacterial and deodorizing performance may be lowered.

In addition, the lactide (lactide) is a biodegradable polymer prepared by using starch, and is mixed with rosin by using a mixture of starch extract and wormwood extract, which are components of the natural mixed resin, and wormwood extract. At the time of manufacture, it functions to complement the function of the natural mixed resin.

In the present invention, it is preferable that the mixed amount of lactide is 15 to 20 parts by weight, and when the mixed amount of lactide is less than 15 parts by weight, the function as a natural mixed resin may be deteriorated. When the amount exceeds 20 parts by weight, there is a concern that the function of the antibacterial and deodorizing performance may decrease as the mixing amount of the herbal components having the relatively antibacterial and deodorizing performance decreases.

The synthetic resin is preferably composed of 80 to 85 parts by weight of ethylene vinyl acetate (EVA) and 15 to 20 parts by weight of low density polyethylene (LDPE).

The ethylene vinyl acetate (EVA) in the present invention serves to maintain the resilience and resilience of the insole as the main resin component of the insole.

Low-density polyethylene (LDPE) has excellent physical properties such as flexibility and chemical resistance, and serves to complement the physical properties of ethylene vinyl acetate (EVA).

In the present invention, the mixing amount of ethylene vinyl acetate (EVA) is preferably 80 to 85 parts by weight, and when the mixing amount of ethylene vinyl acetate (EVA) is less than 80 parts by weight, the physical properties such as flexibility and chemical resistance may decrease in the insole. In the case where the mixed amount of ethylene vinyl acetate (EVA) exceeds 85 parts by weight, the amount of ethylene vinyl acetate (EVA) decreases relatively, so that physical properties such as repulsive elasticity and restoring force may decrease.

In the present invention, the filler is used to improve the impact absorption and cost reduction, it is preferable to use 15 to 20 parts by weight based on 100 parts by weight of the substrate. If the amount of the filler is less than 15 parts by weight, the filler does not express its function. If the amount of the filler is more than 20 parts by weight, it is difficult to control the foaming process as well as the durability of the insole, and thus it is impossible to manufacture a normal foam. There is concern.

And the filler used in the present invention is preferably calcium carbonate or magnesium carbonate.

In the present invention, the stearic acid is to induce flat crosslinking, it is preferable to use 1 to 3 parts by weight based on 100 parts by weight of the substrate. If the amount of stearic acid is out of the above range, the amount of stearic acid used is difficult to control the crosslinking rate, and in many cases, blooming may occur.

In the present invention, the zinc oxide is for promoting crosslinking, preferably 2 to 6 parts by weight based on 100 parts by weight of the substrate. If the amount of zinc oxide is out of the above range, there is a concern that a problem of uncrosslinked or overcrosslinked may occur.

In the present invention, it is preferable to use 0.5 to 3.0 parts by weight of the crosslinking agent based on 100 parts by weight of the substrate. If the amount of the crosslinking agent is less than 0.5 parts by weight, the crosslinking effect may be insufficient, resulting in poor appearance of the foam, poor compression, etc., resulting in problems in durability of the product. If excessively excessive, crosslinking density may increase due to excessive crosslinking, causing the foam to burst.

And the crosslinking agent usable in the present invention is t-butyl peroxy isopropyl carbonate, t-butyl peroxy laurate, t- butyl peroxy acetate, di- t- butyl peroxy phthalate, t- dibutyl per Oxymaleic acid, cyclohexanone peroxide, t-butyl cumyl peroxide, t-butyl hydroperoxide, t-butyl peroxybenzoate, dicumyl peroxide, 1,3-bis (t-butylperoxyisopropyl) benzene, Methyl ethyl ketone peroxide, 2,5-dimethyl-2,5-di (benzoyloxy) hexane, 2,5-dimethyl-2,5-di (t-buperoxy) hexane, di-t-butylperoxide, 2,5-dimethyl-2,5- (t-butylperoxy) -3-hexane, n-butyl-4,4-bis (t-butylperoxy) valerate and a, a'-bis (t- One or more of butyl peroxy) isopropyl benzene can be selected and used.

In the present invention, the crosslinking aid is used to obtain a suitable crosslinking structure for shortening the molding time and improving durability during the peroxide crosslinking, and it is preferable to use 0.2 to 1.0 parts by weight based on 100 parts by weight of the substrate. If the amount of the crosslinking aid is less than 0.2 part by weight, there is a fear that the effect of the crosslinking promotion may be almost insignificant. If the amount of the crosslinking aid is more than 1.0 part by weight, the normal cross-linking may be impossible due to overcrosslinking.

And the crosslinking aid that can be used in the present invention is divinylbenzene, triaryl cyanurate, triaryl isocyanurate, ethylene glycol dimethacrylate, diethyl glycol dimethacrylate, polyethylene glycol dimethacrylate, trimethyl One or more may be selected and used from an all propane trimethacrylate, an aryl methacrylate, a vinyl butyrate, and a vinyl stearate.

In the present invention, the blowing agent is preferably used 3 to 10 parts by weight based on 100 parts by weight of the substrate. When the amount of the blowing agent is less than 3 parts by weight, there is no foaming effect. When the amount of the blowing agent is more than 10 parts by weight, the molding of the foam is not smooth and the durability is lowered.

And the blowing agent usable in the present invention azodicarbonamide-based, diazominoexobenzene-based, n, n'- dinitrosopentamethylenetetraamine-based, p-toluenesulfonylhydrazide-based, p, p ' One or more types can be selected and used from the group which consists of -oxybis- benzenesulfonyl hydrazide system or benzenesulfonyl idraziad.
