The Effect of Kinds and Dosage of Carbon Black on Crack Development of NBR Rubber
摘要
Abstract
Under conduction of cyclic stress,the cracks in NBR will continue to develop until rubber breaks. In this paper,the effect of kinds and dosage of carbon black on crack development of NBR rubber was investigated and the fraction surfaces were observed using SEM. The results showed that the carbon black of N220 had the best effect on depression to crack development in N220,N330 and N550. If the carbon black of N330 is used,the best dosage is 20 or 30 phr.关键词
