摘　　要：研究了响应面法在PVC热稳定剂研究中的使用优势。利用Box—Benhnken中心组合实验设计、响应面分析法和SAS软件，探讨了硬脂酸锌、硬脂酸钙、硬脂酸钡对PVC热稳定性的作用规律，得到了三者对热稳定时间的响应面曲面图。分析图表可知，硬脂酸锌对热稳定时间产生了负面作用，硬脂酸锌和硬脂酸钙之间的交互作用对热稳定时间产生了正面影响，硬脂酸锌与硬脂酸钡之间的交互作用也对热稳定时间产生了正面影响。In this paper, the value of response surface method was studied in the research of PVC heat stabilizers. According to Box-Benhnken design principle, design a response surface analysis of the three factors and three levels of analysis table, and experimental programs, SAS was used to analysis experimental data, which generates response plates about thermal stabilization time evicting by the interaction between ZnSt 2, CaSt2, BaSt2. In the picture, it was figured out that ZnSt2 had a negative linear effect on thermal stabilization time, and there was interaction between ZnSt2and CaSt2as between ZnSt2 and BaSt2.
