| 摘 要： | 以甲基丙烯酸锌(ZDMA)/白炭黑填充氢化丁腈橡胶(HNBR),研究ZDMA/白炭黑并用比、硫化剂DCP用量及硫化时间对HNBR硫化胶结构和性能的影响。结果表明,在填料总量不变的前提下,随着白炭黑用量的增大,ZDMA/白炭黑填充HNBR硫化胶拉伸强度和压缩永久变形先减小后增大,填料分散性下降;随着硫化剂DCP用量的增大,ZDMA/白炭黑填充HNBR硫化胶物理性能和动态性能提高,填料分散性变好。当ZDMA/白炭黑并用比为10/30、硫化剂DCP用量为5～6份、一段硫化条件为160℃×45min、二段硫化条件为150℃×(9～12)h时,ZDMA/白炭黑填充HNBR硫化胶综合性能较好。

| Abstract: | Hydrogenated nitrile rubber(HNBR)was filled with zinc dimethacrylate(ZDMA)/silica,and the effects of ZDMA/silica blending ratio,the addition level of vulcanizator dicumyl peroxide(DCP)and curing time on the structure and properties of HNBR vulcanizates were investigated.The results showed that,the tensile strength and compression set of ZDMA/silica filled HNBR vulcanizate were decreased at first and then increased,the filler dispersibility was declined as the addition level of silica increased while filler ... |
