白炭黑填充氯化聚乙烯/丁腈橡胶并用胶性能的研究

; |2 M+ H  e" A6 D/ g研究了白炭黑对氯化聚乙烯(CM)/丁腈橡胶(NBR)并用胶性能的影响。结果表明,加入多于30份的白炭黑时CM/NBR并用胶的t10和t90均减小;白炭黑对并用胶的补强作用明显,可显著提高拉伸强度,且用量为10~20份时提高迅速,而拉断伸长率在用量变化范围内随白炭黑用量的增加而增加。浸油后,硫化胶耐油性能增加,而耐热老化性能轻微降低。

Effect of silica on the properties of CM/NBR blends was studied.The results showed that the scorch time and optimum curing time of the blends were shortened when silica content was more than 30phr.Silica had significant reinforcing effect to CM/NBR blends,and significantly improved the tensile strength,espcially when silica content was 10~20phr,while the elongation at break increased with the increase of silica content in fixed range.The oil resistance were improved with the addition of silica,while the ..
