摘要

采用多因素分析法,研究了过氧化物硫化剂DCP和甲基丙烯酸锌(ZDMA)的用量对丁腈橡胶/乙华平橡胶(NBR/EVM)并用胶性能的影响.结果表明,在实验设定范围内,随着DCP和ZDMA用量的增加,NBR/EVM硫化胶的Shore A硬度、拉伸强度和撕裂强度均逐渐增大,而回弹性和拉断伸长率呈下降趋势;采用回归分析法研究了 DOP和ZDMA对NBR/EVM性能的影响,经验证发现,建立的数学模型能较为准确地预测胶料的各项力学性能与配合剂用量之间的关系.

Abstract

The effects of peroxide vulcanizing agent DCP and zinc methacrylate(ZDMA)on the properties of nitrile rubber/ethylene-vinyl acetate copolymer(NBR/EVM)blends were studied by multivariate analysis.The results showed that,with the increase of DCP and ZDMA content,the Shore A hardness,tensile strength,and tear strength of NBR/EVM vulcanizate gradually increased,while the resilience and elongation at break showed a decreasing trend.The regression analysis meth-od was used to study the influence trend of DCP and ZDMA on the performance of NBR/EVM,and it was verified that the established mathematical model could accurately predict the relationship between the mechanical properties of the compound and the dosage of compounding agent.
