Abstract

Effect of carbon blacks (CBs) on the stress relaxation and the elastic recovery of uncrosslinked natural rubber (NR) was examined. It was found that if the type of CB is characterized by smaller size and higher structure, the stress relaxation is more delayed and the elastic recovery becomes more active. These results are attributed to the degree of bound rubber, i.e., the interaction between NR and CB.

미가교 천연고무의 응력완화와 탄성복원에 대한 카본블랙의 영향을 조사하였다. 카본블랙의 형태가 보다 작고 높은 구조의 특징을 가질 때 응력완화는 더 지연되었고 탄성복원은 더 활발하였다. 이 결과는 결합고무의 크기, 즉 천연고무와 카본블랙의 상호작용의 크기에 기인하였다.
