본 연구에서는 Ethylene.α.Olefin copolymer 블렌드 발포체의 구조적, 기계적, 가교특성에 대한 실험을 실시하였으며 다음과 같은 결론을 얻었다. 1) EVA 단독의 경우보다 Ethylene.α.Olefin copolymer 단독 및 블렌드의 경우 기계적 강도가 개선됨을 알 수 있었다. 2) 발포체의 기계적 특성은 발포체의 cell을 구성하고 있는 분자간의 결합력과 cell wall과 cell ribs간의 구조적 특성에 기인하며 가교밀도가 증가에 따른 기계적 특성 차이가 나타났다. 또한 octene의 함량에 따라 기계적 특성의 변화를 나타내었다. 3) octene 함량별 발포체를 동일 비중에서 비교하였을 경우, EVA단독 발포체에 비하여 ...

Ethylene vinyl acetate(EVA) foam is used widely for midsole, a part of footwear. On the other hand, it is well know that ethylene-1-octene copolymer(Engage) for midsole material has excellent elasticity, flexiblilty, abrasion resistance, chemical resistance when it is cross-linked after that foamed. The Ethylene-α-Olefin copolymer manufacture technique where the density control is possible was developed by Phillips Petroleum. The technique will be able to manufacture a Ethylene-α-Olefin copolymer with weather polymerization was developed by Union Carbide. Generally, the foam undergoes the influence in compliance with closed-cell structure, cell size and density plentifully. The density of the foam changes according to cross-linking agent, curing time, mold temperature, formation condition, base Polymer, foaming speed and the gas quantity. When changes like this conditions, the manufacture of foam has the various physical properties which is possible. In this study, used Ethylene 1-Octene copolymer and manufactured evaluated the foam at 1-octene content and by about the quality instead of EVA. Ethylene-1-octene the processing technique is hard to satisfy high viscosity and because of elasticity. Ethylene-1-octene was used until now with EVA physical properties reinforcements. But made the foam with Ethylene-1-octene, independence almost there was not a case which. In order to complement an adhesion property the fixed quantity which blend polarity Polymer and tried to evaluate about that properties. In this study, experimented about structural, mechanical and curing of Ethylene α-Olefin copolymer blended foam. After ethylene-1-octene copolymer was manufactured that crosslink characteristics of the blends and cell structures and mechanical properties of the foam were studied. The following results are obtained, 1) The mechanical strength of Ethylene-α-Olefin copolymer blended foam are improved compared with EVA 2) According to increases Crosslinking density, the mechanical quality difference appeared. According to octene content put out the change of mechanical properties. 3) When compared the mechanical properties of the foam which have same densities, tensile strength, rebound resilience, and compression set properties of the ethylene-α-Olefin copolymer foam were excellent compared with EVA.
