回归分析法研究补强剂对NBR/EVM并用胶性能的影响

Study on the Effect of Reinforcing Agent on Properties of NBR/EVM Blends by Regression Analysis

采用回归分析法研究了FEF和ZDMA用量对NBR/EVM并用胶性能的影响。结果表明,在试验范围内,随着FEF或ZDMA用量的增加,硫化胶的硬度、拉伸强度、撕裂强度、100%定伸应力、压缩永久变形逐渐增大,而拉断伸长率逐渐减小,耐油性能得到改善;由等高线曲线可以清楚地看出两者用量对性能影响的规律,并可以预测胶料的各项物性与配合剂用量之间的关系。

The effect of FEF and ZDMA amount on the properties of NBR/EVM blends were studied by using regression analysis method.With the increase of FEF or ZDMA amount,the properties of NBR/EVM vulcanizate,such as hardness,tensile strength,tear strength,100% modulus and compression set increased,but elongation at break decreased,the oil-resistance was improved.The relationship between mechanical properties and additives amount of the NBR/EVM blends would be predicted by regression analysis method.
