| 中文摘要: |
| 采用自定义响应曲面法进行乙丙橡胶的试验设计和方差分析,建立起炭黑和石蜡油填充份数对乙丙橡胶加工性能和物理机械性能影响的数学模型。数学模型包括七个根据线性或二阶交互作用建立的拟合方程,拟合方程均显著(p<0.05)且拟合优度R2>0.90。建立的数学模型可以根据配方性能要求自动匹配出合适的炭黑和石蜡油配比范围,实验结果与设计要求的差异在5%以内。本文介绍的采用自定义响应曲面建立数学模型的方法可从两因子增至更多因子,具有较强的拓展性和实用性。 |
| 英文摘要: |
| Customized Response Surface Methodology (RSM) is applied to investigate the influence of carbon black and paraffin oil on the processability and physical and mechanical properties of ethylene-propylene rubber (EPDM) compound and a mathematical model is constructed based on design of experiment and analysis of variance (ANOVA). In the mathematical model, 7 fitting equations have been established by means of linear or 2 factorial interactions which is significant with p<0.05 and goodness of fit >0.90. The above mathematical model can be applied to find a suitable range of carbon black and paraffin oil based on the desired performance of the compound. The actual experimental results are highly consistent with the desired performance within 5% error. The customized RSM can be applied to more factorial to support the EPDM compound design which has an excellent application extensibility. |
