충격방지 및 통기성 신발깔창재Shockproof and breathable shoe insole

제1도는 본 고안의 일부절개 사시도.1 is a partially cutaway perspective view of the present invention.

제2도는 본 고안의 일부확대 단면도.2 is a partially enlarged cross-sectional view of the present invention.

* 도면이 주요부분에 대한 부호의 설명* Explanation of symbols for the main parts of the drawing

1 : 깔창재 2 : 단섬유1: insole material 2: short fibers

3 : 콜크분말 4 : 고무 및 플리우레탄 혼합체3: cork powder 4: rubber and polyurethane mixture

본 고안은 다공질 조직으로 결합된 천연콜크, 단섬유를 고무 및 폴리우레탄 점결재로 결합 구성시키므로서 천연콜크의 특성을 살리며 우수한 신축성, 내점결성 및 통기성을 갖일수 있는 신발깔창재에 관한 것이다. 종래에는 EVA, PVC, 폴리우레탄등 합성수지재를 저발포하여 신발깔창재로 사용하여 왔으나 비연속성의 단위기공의 집합체로 되어 있어 통기성이 없으며 이로 인해 땀의 제거가 곤란하여 무좀발생의 원인이 될뿐 아니라 어느 기간 사용함에 따라 단위기공을 형성하는 벽면과 벽면이 가압에 의하여 집합되므로서 탄성을 상실하게 되고 따라서 충격방지능이 부족해진다.The present invention relates to a shoe insole material that can have excellent elasticity, caking resistance, and breathability while utilizing the properties of natural coke by combining natural coke and short fibers combined with a porous structure with rubber and polyurethane caking material. Conventionally, EVA, PVC, polyurethane, low-foam synthetic resin materials have been used as a shoe insole material, but it is a non-continuous unit of pores, it is not breathable and this is difficult to remove sweat, causing only athlete's foot However, with use for a certain period of time, the wall surface and the wall surface forming the unit pores are gathered by pressing, so that the elasticity is lost and thus the shock resistance is insufficient.

일반적으로 합성수지재는 천연콜크에 비해 열전동성이 크므로 단열성과 흡습성이 좋지않아 동상의 원인이 될 수 있다.In general, synthetic resin materials have greater thermal conductivity than natural cork, which may cause frostbite due to poor thermal insulation and hygroscopicity.

최초에는 콜크분말을 접착제로 결착시켜 판상체로 형성한 것이 있으나 콜크 자체의 단점으로 나타나는 내점결성의 부족으로 부러지기 쉽다.Initially, the cork powder was bound with an adhesive to form a plate-like body, but it is easily broken due to the lack of caking resistance which is a disadvantage of the cork itself.

본 고안은 종래 신발깔창제의 단점을 개선하여 착화시 촉감이 좋고 충격방지의 효과가 크며 통기성 및 내점결성이 우수한 신발깔창제를 얻음에 목적이 있다 하겠다.The present invention is to improve the disadvantages of the conventional shoe insole is to feel good when ignited, the effect of impact resistance is large, and to obtain a shoe insole excellent in breathability and corrosion resistance.

본 고안에 의한 신발깔창재는 천연콜크분말, 단섬유(파사)을 고무 및 폴리우레탄으로 혼합결착시켜 구성한 판상체의 신발깔창제라 할 수 있으며 그 구조를 제1도로서 설명하면 깔창재(1)는 내부에 불규칙적으로 산재한 단섬유(2)와 콜크분말을 고무 및 폴리우레탄혼합체(4)로 결착시켜 구성한 판상체이다.The shoe insole material according to the present invention can be referred to as a shoe insole agent of a plate-like body formed by mixing and binding natural cork powder and short fibers (pasa) with rubber and polyurethane, and the structure of the insole material (1) It is a plate-shaped body formed by binding short fibers (2) and cork powder irregularly scattered therein with rubber and polyurethane mixture (4).

참고로 본 고안에 의한 신발깔창재의 제조방법을 기술하면 중량비로 콜크분말 1부에 대하여 메칠에칠케튼에 용해시킨 폴리우레탄 0.1-0.15부와 단섬유(파사)0.3부-0.35부를 혼하여 건조시킨후 여기에 폴리우레탄과 같은량의 메칠에칠케톤에 용해시킨 고무를 제차혼합하여 열장치가 된 푸레스토판상체로 성형하여 온도 150-200℃에서 가류처리 하므로서 완성된다.For reference, the manufacturing method of the shoe insole according to the present invention is dried by mixing 0.1-0.15 parts of polyurethane dissolved in methyl ethyl ketone and 0.3 part-0.35 parts of short fibers (fasa) with respect to 1 part of cork powder by weight ratio. After this, the rubber dissolved in the same amount of methyl ethyl ketone as the polyurethane is mixed with the first, and molded into a furnace-like plate which becomes a heat device, and is completed by vulcanizing at a temperature of 150-200 ° C.

이와 같은 신발깔창재를 구성하는 콜크는 원래 다공질세포로서 인치입방에 약200만개의 다고질세포가 있으며 각각의 세포들은 수밀성이고 탄성이 있는 격실이므로 고도의 충격을 흡수하는 우레탄이 있고 가벼운 것이 특징이라 할 수 있으며 고무와 폴리우레탄의 혼합체는 콜크와 단섬유를 강인하게 결착하여 콜크의 단점인 점결성을 보강한다. 또 단섬유는 각 방향으로 배열되어 내점결성을 향상시키며 종횡으로 통기성을 제공하고 흡습성을 향상시킨다.Cork, which constitutes such shoe insole material, is originally a porous cell, and there are about 2 million polycytic cells in the cubic inch. Each cell is a watertight and elastic compartment, so it has urethane that absorbs high impact and is light. The mixture of rubber and polyurethane strongly binds the cork and the short fibers to reinforce the coking property which is a disadvantage of the cork. In addition, the short fibers are arranged in each direction to improve the caking resistance, to provide air permeability vertically and horizontally and to improve hygroscopicity.

따라서 본 고안에 의한 신발깔창재는 종래의 것에 비해 착화시 촉감이 좋고 가벼우며 충격흡수력이 크고 탄성이 높다 그밖에도 흡습성과 통기성이 우수하여 무좀방지에 큰 효과를 얻을 수 있고 낮은 열전도율로 단열효과를 얻을수 있어 앞으로 신발깔창재로 큰수요가 기대되는 제품이라 할 수 있다.Therefore, the shoe insole material according to the present invention has a good touch when lighted, light weight, high shock absorption capacity and high elasticity. In addition, it is excellent in hygroscopicity and breathability, and can obtain a great effect on athlete's foot prevention and a thermal insulation effect with low thermal conductivity. It is a product that is expected to have great demand as a shoe insole in the future.
