기능성 인솔용 발포체 조성물 및 이를 이용한 무접착 다층 기능성 인솔 제조방법Foam composition for functional insole and method for manufacturing non-adhesive multilayer functional insole using the same
본 발명은 기능성 인솔용 발포체 조성물 및 이를 이용한 무접착 다층 기능성 인솔 제조방법에 관한 것이다.The present invention relates to a foam composition for functional insole and a method for manufacturing an adhesiveless multi-layer functional insole using the same.
종래의 기능성 인솔(insole)은 여러 고분자와 발포제, 가교제 등을 이용하여 배합 → 발포(가류) → 수평 /수직/프로파일(Profile) 재단 → 원단 및 기능성 발포체 접착제 도포 → 발포체 적층 및 압착 → 가열 → 성형 → 재단의 공정으로 제조된다.Conventional functional insole is formulated using various polymers, blowing agents, crosslinking agents, etc. → Foaming (vulcanization) → Horizontal / Vertical / Profile cutting → Dyeing and functional foaming adhesive application → Foam lamination and pressing → Heating → Forming → cutting process.
여러 기능성 발포체를 도입하기 위해 각각의 기능성 발포체를 개별 발포/재단 공정 및 접착 공정을 거치기 때문에 제조 시간이 길며, 제조 공정이 복잡한 문제가 있다.In order to introduce various functional foams, the respective functional foams are subjected to individual foaming / cutting and bonding processes, resulting in long manufacturing time and complicated manufacturing processes.
구체적으로, 종래에는 각각의 기능을 부여하기 위해 조성물 배합이 상이하여 발포(가류) 조건이 다르며, 발포 후 발포체의 발포율, 수축률 등이 다르게 나타기 때문에 각각의 기능성 발포체를 제조 후 접착제로 접착하여 인솔을 제작하여야 하므로 제조 시간이 상당히 길다는 문제가 있다.Specifically, conventionally, in order to impart respective functions, the compositions are different and the foaming (vulcanizing) conditions are different. Since the foaming rate and the shrinkage ratio of the foam are different after foaming, the respective functional foams are bonded with an adhesive There is a problem in that the manufacturing time is considerably long since the insole must be manufactured.
또한, 기존의 기능성 인솔을 제조할 때 각각의 기능성 발포체를 제조하여 형태에 맞춰 재단 후 접착 공정을 거치게 되며, 접착 공정은 인화성 물질 취급으로 화재의 위험이 있으며, 작업자의 눈과 호흡기관에 자극을 줄 수 있고 피부와 접촉 시 피부트러블, 발암의 가능성이 높고 장기간 노출로 인해 건강에 심각한 손상을 유발할 수도 있다. 또한 솔벤트 배출로 인해 후처리 비용이 발생하며 주변 장비를 부식시켜 장비의 수명을 저하 시키는 문제가 있다.In addition, when manufacturing conventional functional insole, each functional foam is manufactured and subjected to a post-cutting adhesion process in accordance with the shape. In the bonding process, there is a risk of fire due to handling of flammable material, In case of contact with skin, skin trouble, possibility of carcinogen is high and long term exposure may cause serious damage to health. In addition, there is a problem that the discharge of the solvent causes post-treatment costs and corrosion of the peripheral equipment, thereby reducing the life of the equipment.
따라서, 다양한 기능성 발포체를 이용하여 제조 시간이 단축될 수 있으며, 환경 친화적인 무접착 다층 기능성 인솔 제조방법에 대한 연구 개발이 시급한 실정이다.Therefore, the manufacturing time can be shortened by using various functional foams, and research and development of an environmentally friendly method for manufacturing an adhesiveless multi-layer functional insole is urgently required.
본 발명의 목적은 종래 각각의 기능성 발포체를 제조하여 형태에 맞춰 재단 후 접착 공정을 통해 제조된 인솔의 제조방법을 대체하고자 프레스를 이용하여 무접착 방식으로 다층 기능성 인솔을 제조하는 방법을 제공하는 데에 있다.It is an object of the present invention to provide a method of manufacturing a multi-layer functional insole in a non-stick manner by using a press in order to replace the manufacturing method of the insole manufactured by the post-cutting adhesion process in accordance with the shape of each conventional functional foam, .
상기 목적을 달성하기 위하여, 본 발명은 에틸렌-비닐 아세테이트 공중합체(ethylenevinylacetate copolymer) 수지 또는 에틸렌-α-올레핀 공중합체(ethylene-α-olefin copolymer) 수지 10 내지 40 중량%, 에틸렌-비닐 아세테이트 공중합체 또는 에틸렌-α-올레핀 공중합체 층간 혼용 수지 5 내지 15 중량%, 발포체 고분자 40 내지 70 중량%, 고무(rubber) 1 내지 10 중량%, 발포속도 조절제 2 내지 3 중량%, 첨가제 1 내지 2 중량%, 점착제(tackifier) 1 내지 2 중량%, 발포제 3 내지 7 중량%, 가교제 0.5 내지 1.5 중량%; 및 가교조제 0.1 내지 0.5 중량%를 포함하는, 기능성 인솔용 발포체 조성물을 제공한다.In order to achieve the above object, the present invention provides a thermoplastic resin composition comprising 10 to 40% by weight of an ethylene-vinyl acetate copolymer resin or an ethylene-α-olefin copolymer resin, an ethylene- 5 to 15% by weight of an ethylene /? - olefin copolymer interlayer mixture resin, 40 to 70% by weight of a foam polymer, 1 to 10% by weight of rubber, 2 to 3% by weight of a foaming rate controlling agent, 1 to 2% by weight of a tackifier, 3 to 7% by weight of a blowing agent, 0.5 to 1.5% by weight of a crosslinking agent; And 0.1 to 0.5% by weight of a crosslinking auxiliary.

본 발명에 따른 기능성 인솔용 발포체 조성물 및 이를 이용한 무접착 다층 기능성 인솔 제조방법은 접착 공정을 생략함으로써 유해 작업 개선, Insole 내부의 유해 물질 제거, 물성 향상, 제조 공정 단축, 생산성 향상, 제조 비용 절감 등의 장점이 있다.The foam composition for a functional insole according to the present invention and the method for manufacturing an adhesiveless multi-layered functional insole using the same can improve harmful operations, remove toxic substances in the insole, improve physical properties, shorten the manufacturing process, .
또한, 본 발명으로 제조된 무접착 다층 기능성 인솔은 다단으로 적층된 기능성 층이 서로 다른 기능을 가지고 있기 때문에 신발 착용 시 착용감을 향상시킨다.In addition, the non-adhesive multi-layer functional insole manufactured by the present invention improves the fit feeling when shoes are worn because the multi-layered functional layers have different functions.
기능성 Insole은 보행 또는 운동 시 체중이 한쪽으로 쏠리면서 생기는 발의 통증과 발목 관절의 부담을 줄일 수 있으며, 그 효과를 증대하기 위해 2 이상의 발포체를 이용하여 제조함으로써 충격 흡수층과 탄성층이 보행 시 1차적으로 발바닥의 충격을 충격흡수 층에서 완화하며, 2차적으로 탄성 층에서 압축 복원력을 높이고, 베이스 층에서 아치와 뒤꿈치 형상을 잘 유지함으로써 하중의 분포를 분산시켜 보행이 원활하게 이루어지는 효과를 갖는다. Functional Insole can reduce foot pain and burden of ankle joint caused by weight gain during walking or exercise, and it is manufactured by using two or more foams to increase the effect, so that the impact absorbing layer and the elastic layer can be used as a primary The impact of the soles of the sole is relieved in the impact absorbing layer, the compressive restoring force is increased secondarily in the elastic layer, and the arch and the heel shape are well maintained in the base layer.
또한 종래 인솔은 보행 시 발생되는 땀이 원단으로 쓰며 들어 장시간 착용 시 냄새의 원인이 되며, 세척 시 원단과 발포체 층의 접착력이 떨어져 수명이 저하되는 문제가 있으나, 원단을 대체한 기능성 발포체는 소재의 다양성으로 여러 기능을 가질 수 있으며, 보행 후 땀이 차거나 냄새가 날 때 쉽게 세척하여 사용할 수 있으며, 발이 건조한 사람의 경우 보습 효과가 있어 갈라짐이나 각질 발생을 저하 시킬 수 있다.In addition, the conventional insole has a problem that the sweat generated during walking is used as a fabric and causes the smell when worn for a long time, and the adhesive force between the fabric and the foam layer during washing deteriorates to deteriorate the service life. However, It can have various functions with diversity, and can be easily cleaned when sweating or smelling after walking, and in the case of a person with dry feet, moisturizing effect may be caused and cracking or keratinization may be reduced.

또한 본 발명은 상기 조성물을 이용하여 2 이상의 시트를 준비하는 단계; 상기 2 이상의 시트를 적층하는 단계; 상기 적층된 시트를 프레스에 투입하여 발포시켜 다층 기능성 발포체를 준비하는 단계; 상기 다층 기능성 발포체를 성형하는 단계; 및 상기 성형된 다층 기능성 발포체를 재단 및 사상하여 다층 기능성 인솔을 제조하는 단계;를 포함하는, 무접착 다층 기능성 인솔 제조방법을 제공한다.The present invention also relates to a method for preparing a sheet, comprising: preparing two or more sheets using the composition; Stacking the at least two sheets; Introducing the laminated sheet into a press and foaming to prepare a multilayer functional foam; Molding the multi-layer functional foam; And cutting and shaping the molded multilayer functional foam to produce a multi-layer functional insole.
상기 조성물을 이용하여 2 이상의 시트를 준비하는 단계에서, 다층 기능성 인솔을 제조하기 위해서 각각의 기능성 인솔용 발포체 조성물의 발포율, 수축률, 가교도 등을 적절히 조절하여 2 이상의 시트를 준비하여야 한다. In preparing two or more sheets using the above composition, at least two sheets should be prepared by appropriately adjusting the foamability, shrinkage, and degree of crosslinking of each foam composition for a functional insole in order to produce a multi-layer functional insole.
상기 2 이상의 시트를 적층하는 단계에서, 시트 간의 박리현상 발생 시 폴리에틸렌 공중합체 수지, 폴리프로필렌 공중합체 수지, 스타이렌 엘라스토머 수지, 올레핀 블록 공중합체 수지, 및 폴리올레핀 엘라스토머 수지로 이루어진 군에서 선택된 2 이상의 수지로 조합된 에틸렌-비닐 아세테이트 공중합체 또는 에틸렌-α-올레핀 공중합체 층간 혼용 수지 및 접착제를 사용하여 2 이상의 시트를 적층시킨다.In the step of laminating the two or more sheets, at least two resins selected from the group consisting of a polyethylene copolymer resin, a polypropylene copolymer resin, a styrene elastomer resin, an olefin block copolymer resin, and a polyolefin elastomer resin Or an ethylene-vinyl acetate copolymer or an ethylene-alpha-olefin copolymer interlayer-mixing resin and an adhesive are used to laminate two or more sheets.
상기 다층 기능성 발포체를 준비하는 단계는 상기 적층된 시트를 프레스에 투입하여 120 내지 180℃에서 120 내지 180 kgf/cm2의 압력으로 5 내지 15분 동안 발포시켜 다층 기능성 발포체를 준비하는 단계일 수 있으며, 이에 제한되는 것은 아니다.The step of preparing the multilayer functional foam may be a step of putting the laminated sheet into a press and foaming at 120 to 180 ° C at a pressure of 120 to 180 kg f / cm 2 for 5 to 15 minutes to prepare a multilayer functional foam But is not limited thereto.
상기 다층 기능성 발포체를 준비하는 단계에서, 발포 배율은 110 ~ 250%까지 선택적으로 제조가 가능하다.In the step of preparing the multi-layered functional foam, the foaming magnification can be selectively made up to 110 to 250%.
구체적으로, 각각의 기능성 발포체는 발포 후 초기 발포율과 냉각 후 발포율을 가지는데 정상적인 형태의 발포체를 제조하기 위해서 각각의 기능성 인솔용 발포체 조성물의 초기 발포율과 냉각 후 발포율을 동일하게 가져가야 된다. Specifically, each of the functional foams has an initial foaming ratio after foaming and a foaming ratio after cooling. In order to prepare a foam in a normal form, the foaming ratio of each foaming composition for each functional insole must be equal to the foaming ratio after cooling do.
예를 들면, 기능성 발포체의 제1층은 초기 발포율이 200%이고, 냉각 후 발포율이 190%이며, 기능성 발포체의 제2층은 초기 발포율이 190%이고, 냉각 후 발포율이 185%인 기능성 인솔용 발포체 조성물을 이용하여 발포를 하였을 경우 뒤틀림, 갈라짐 등의 발포 형상 불량이 발생이 된다. 따라서, 두 가지 이상의 기능성 발포체를 이용하여 다층 기능성 인솔을 제조하기 위해선 적층된 시트가 동일한 초기 발포율 및 냉각 후 발포율을 가져야 한다. For example, the first layer of the functional foam has an initial foaming ratio of 200%, a foaming ratio after cooling of 190%, a second layer of functional foaming has an initial foaming ratio of 190%, a foaming ratio after cooling of 185% When foaming is carried out by using the foam composition for a functional insole, the foaming defects such as warping and cracking may occur. Thus, in order to prepare a multilayered functional insole using two or more functional foams, the laminated sheet must have the same initial foaming ratio and a foaming ratio after cooling.
상기 다층 기능성 발포체로 제품을 성형하는 방법은 가열성형 방법 또는 냉각성형 방법이 있다.The method for molding the product with the multi-layer functional foam includes a heat molding method or a cooling molding method.
구체적으로, 가열성형 방법은 다층 기능성 발포체를 성형 몰드가 장착된 프레스에 투입 후 5 내지 7분 동안 140 내지 160℃로 가열 후 실온으로 냉각하여 성형하는 것일 수 있으며, 이에 제한되는 것은 아니다.Specifically, the heat molding method may include molding the multi-layered functional foam into a press equipped with the molding mold, heating it to 140 to 160 ° C for 5 to 7 minutes, cooling it to room temperature, and molding.
냉각성형 방법은, 다층 기능성 발포체를 120 내지 170℃로 가열한 후 성형 몰드가 장착된 프레스에 투입하여 2 내지 5분 동안 냉각하여 성형하는 것일 수 있으며, 이에 제한되는 것은 아니다.The cooling molding method may include, but is not limited to, heating the multi-layered functional foam at 120 to 170 캜, placing it in a press equipped with a molding mold, cooling it for 2 to 5 minutes, and molding.
구체적으로, 상기 다층 기능성 발포체를 성형하는 단계에서, 가열성형 방법 또는 냉각성형 방법에 따라 가열을 할 경우 적층된 각각의 다층 기능성 발포체의 열 수축률이 다르면 또한 휘어짐, 뒤틀림 현상이 발생하게 된다. Specifically, in the step of molding the multi-layer functional foam, when heating is carried out according to the heat molding method or the cooling molding method, when the heat shrinkage ratios of the respective multi-layer functional foams stacked are different, warping and warping phenomena also occur.
이를 해결하기 위해 각각의 기능성 인솔용 발포체 조성물의 가교시간, 가교온도, 가교밀도 및 열 수축 물성을 동일하게 하여야 한다. 기능성 발포체 층간 박리현상은 각각의 기능성 인솔용 발포체 조성물에 폴리에틸렌 공중합체 수지, 폴리프로필렌 공중합체 수지, 스타이렌 엘라스토머 수지, 올레핀 블록 공중합체 수지, 및 폴리올레핀 엘라스토머 수지로 이루어진 군에서 선택된 2 이상의 수지로 조합된 에틸렌-비닐 아세테이트 공중합체 또는 에틸렌-α-올레핀 공중합체 층간 혼용 수지 및 점착성 수지를 첨가하여 층간 박리현상을 해결할 수 있다. In order to solve this problem, the crosslinking time, crosslinking temperature, crosslinking density and heat shrinkage properties of the respective foam compositions for functional insole should be the same. The interfacial peeling phenomenon of the functional foams is caused by a combination of two or more resins selected from the group consisting of a polyethylene copolymer resin, a polypropylene copolymer resin, a styrene elastomer resin, an olefin block copolymer resin and a polyolefin elastomer resin to each of the foam compositions for functional insole The interlayer delamination phenomenon can be solved by adding an ethylene-vinyl acetate copolymer or an ethylene-alpha -olefin copolymer interlayer-mixing resin and a tackifying resin.
다층 기능성 발포체를 제조하기 위해서는 각각의 기능성 인솔용 발포체 조성물을 초기 발포율, 냉각 발포율, 가교시간, 가교온도, 가교밀도, 열 수축성, 층간 혼용 수지, 점착성 수지 등을 동일하게 맞춰 제조를 하여야 하며, 이렇게 제조된 기능성 인솔용 발포체 조성물을 시트화 하여 다층 적층함으로써 2 이상의 기능성 발포체를 선택적으로 제조할 수 있다.In order to produce a multi-layer functional foam, the foam composition for each functional insole must be prepared in the same manner as the initial foam ratio, the cooling expansion ratio, the crosslinking time, the crosslinking temperature, the crosslinking density, the heat shrinkability, the interlayer resin, , And a foam composition for a functional insole manufactured as described above is sheeted to form a multilayer laminate, whereby two or more functional foams can be selectively produced.
