Abstract

Different amounts of foaming agents were employed in natural rubber(NR)/butadiene rubber(BR) blends to understand the foaming behavior in presence of nano-reinforcing agent, zinc methacrylate (ZMA). The ZMA greatly improved most of the mechanical properties of the rubber foams, however it did not show considerable effect on the cell morphology, such as cell size, density and porosity. It was also observed that the foaming agent concentration affected all the mechanical parameters. When the content of foaming agent was increased, the number of foams was increased leading to a decrease in density of the compounds. But the size and distribution of foams remained unchanged with increased foaming agent. The effect of high styrene-butadiene rubber (HSBR) was also studied. The size of cells became smaller and the cell uniformity was improved with increasing HSBR. The foam rubber compounds showed much efficient energy absorbing capability at higher strains.

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 따라 발포고무의 기계적 물성은 크게 영향을 받는 것으로 나타났다. 발포제 함량 증가에 따라 발포도가 증가하였고, 이는 발포고무의 밀도감소로 나타났지만, 발포입자의 크기나 분산성은 크게 영향을 받지 않았다. 고함량 스티렌-부타디엔 고무(HSBR)의 영향도 함께 조사하였다. HSBR 함량 증가에 따라 발포입자의 크기는 작아졌고 분산성은 향상되었다. 발포고무는 대변형에서 에너지 흡수성이 뛰어난 것으로 나타났다.
