用动态变换模型设计阻燃ABS配方

Dynamic Transform Model for Formulation Design of Flame Retardant ABS

运用试验设计的方法 ,建立了反映阻燃ABS共混体系中组成与性能间相关联的动态变换模型。实验结果表明 :PVC对体系的阻燃性贡献显著 ,且与Sb2 O3 有协同作用。ABS用量的增加可明显改善共混体系的韧性。CPE除具有良好的阻燃性外 ,对PVC和ABS均有很好的增韧。加入少量烃类加工改性剂 (TR)利于CPE增韧PVC。当显著性水平α为 0 .0 1时 ,该数学模型与实际情况拟合良好 ,各项性能的回归值与实测值的误差基本在 10 %以内 ,可用来依据产品性能的要求拟定配方 。

A dynamic transform model for the relationship between composition and properties of an ABS blend system was obtained using experimental design method. It was showed that, PVC had remarkable contribution to the flame-retardancy, and had synergistic effects with Sb 2O 3. The toughness of the blend system could be improved with increasing of the amount of PA-747 of ABS. CPE had effects not only on flame-retardancy, but also on the toughness. TR also increased the impact strength of blend system. With the notability level α=0.01, the regression data matched the experimental data satisfactorily and the error was within 10 percent.
