Abstract: 본 발명은 고무 Latex(Latex)에 물로부터 호화 시킨 전분 용액을 직접 블렌드(Blend) 하여 원료고무와 충전제를 화학적으로 블렌드 한 고무 조성물이다. 이 때에 고무 Latex와 전분 간의 커플링제(Coupling-agent)로써 레조시놀-포름알데히드(Resorcinol-formaldehyde)를 이용하며, 이를 이용하여 가황 고무 컴파운드(Compound)를 제조한다. 고무 Latex와 호화 전분 용액의 블렌드 시에 커플링제로 레조시놀-포름알데히드를 사용하면 고무와의 친화력이 떨어져 인장강도가 크게 저하되는 문제와 물에 잘 녹는 전분의 특성상 용액상태로 블렌드 시에 일어나는 전분의 손실을 해결할 수 있으며, 그 양의 첨가비에 따라 가황 고무 컴파운드의 물성을 변화시킬 수 있다.
