Abstract

Styrene-butadiene rubber (SBR) latex compounds filled with starch-bamboo charcoal powder hybrids were prepared by latex compounding method. The morphology, mechanical properties and thermodynamic properties of the SBR/starch/bamboo charcoal composites were investigated. The particle size of starch and bamboo charcoal powder was measured by particle size analyzer. SEM was used to confirm the uniform dispersion of starch-bamboo charcoal hybrids in the matrix. The results indicated that the bamboo charcoal could improve the mechanical properties (tensile strength, modulus, and hardness), filler network strength and filler-polymer interaction of compounds. The hybrid with best ratio was made from 15 phr starch and 5 phr bamboo charcoal, which has good dispersion state and great tensile strength. From the results of TGA, the initial decomposition temperature also increased gradually, with the bamboo charcoal ratio increased.


스티렌-부타디엔 고무(SBR) 라텍스와 전분, 대나무 숯을 라텍스 블렌딩 방법으로 혼합하여 SBR/전분/대나무 숯 복합체를 제조하였다. 전분과 대나무 숯의 조성에 따라 모폴로지, 기계적 물성, 열적 특성을 조사하였다. 전분과 대나무 숯의 입자크기를 확인하였고, 전자현미경(SEM)을 이용하여 전분과 대나무 숯을 함께 사용한 경우 분산성이 향상되는 것을 확인하였다. 대나무 숯이 들어가면서 충전제-충전제, 충전제-폴리머 상호작용이 증가하는 것을 관찰하였다. 또한 대나무 숯의 함량이 증가할수록 인장강도, 탄성률, 경도의 향상이 보였으며 15 phr의 전분과 5 phr의 대나무 숯이 들어간 경우 우수한 분산성으로 인해 가장 높은 인장강도를 보였다. 열적 안정성은 대나무 숯의 함량이 증가함에 따라 초기 분해 온도가 증가하였다.
