摘要: 나노보강제의 하나인 아연 메타아크릴레이트 (ZMA)로 보강된 천연고무(NR)/부타디엔고무(BR) 블랜드에 발포제 함량을 달리하여 적용하여 발포거동을 관찰하였다. ZMA 첨가에 따라 전반적인 발포고무의 물성은 향상되었지만, 발포입자크기, 밀도, 발포도 등 발포입자의 모폴로지에는 크게 영향을 미치지 않았다. 발포제의 함량에 기계적 받는 것으로 나타났다. 함량 증가에 발포도가 증가하였고, 이는 밀도감소로 나타났지만, 크기나 분산성은 받지 고함량 스티렌-부타디엔 고무(HSBR)의 영향도 함께 조사하였다. HSBR 크기는 작아졌고 향상되었다. 발포고무는 대변형에서 에너지 흡수성이 뛰어난 【Different amounts of foaming agents were employed in natural rubber(NR)/butadiene rubber(BR) blends to understand the behavior presence nano-reinforcing agent, zinc methacrylate (ZMA). The greatly improved most mechanical properties rubber foams, however it did not show considerable effect on cell morphology, such as size, density and porosity. It was also observed that agent concentration affected all parameters. When content increased, number foams increased leading a decrease compounds. But size distribution remained unchanged with agent. high styrene-butadiene (HSBR) studied. cells became smaller uniformity increasing HSBR. foam compounds showed much efficient energy absorbing capability at higher strains.】
