| 中文摘要: |
| 应用二次响应曲面试验设计法研究无卤低烟阻燃三元乙丙橡胶（LSOH-EPDM）电缆绝缘材料的阻燃体系和阻燃性能，建立不同性能指标的回归方程。结果表明：采用响应曲面试验设计法得出的LSOH-EPDM绝缘材料不同性能指标的回归方程预测值与试验值吻合性较好；随着镁铝水滑石、氢氧化铝和氢氧化镁用量的增大，胶料的阻燃性能提高，物理性能呈下降趋势；3种阻燃剂的配比对阻燃性能影响显著，采用镁铝水滑石、氢氧化铝和氢氧化镁用量分别为67，53和59份的阻燃体系的LSOH-EPDM胶料具有良好的阻燃性能、耐高温性能和耐油性能；采用LSOH-EPDM绝缘材料生产的单芯阻燃A类电缆阻燃性能提高，整体材料成本降低。 |
| 英文摘要: |
| The flame retardant system and flame retardant property of zero halogen，low smoke and flame retardant EPDM（LSOH-EPDM） cable insulating material were investigated by quadratic response surface methodology experimental，and the regression equations with different properties index were established.The results showed that，the predicted values of regression equation for different properties index of LSOH-EPDM insulating material obtained by quadratic response surface methodology experimental were in good agreement with the experimental values.With the increase of Mg-Al hydrotalcite，Aluminum hydroxide and Magnesium hydroxide amount，the flame retardant property of compound was improved and the physical properties showed a downward trend.The proportions of three kinds of flame retardants had significant effect on the flame retardant property，The LSOH-EPDM compound with 67 phr Mg-Al hydrotalcite，53 phr Aluminum hydroxide and 59 phr Magnesium hydroxide had good flame retardant property，high temperature resistance and oil resistance.The flame retardant property of the single core flame retardant class A cable produced from LSOH-EPDM insulating material was improved，and the overall material cost was reduced. |
