摘要(Abstract)：

以聚对苯二甲酸丁二醇酯(PBT)和导电TiO_2为原料,硬脂酸镁为分散剂,利用熔融混合的方法制备导电母粒。采用扫描与透射电镜、高阻仪等测试手段,重点分析了导电TiO_2及分散剂含量对导电母粒的电性能及颗粒分散性的影响。结果表明:随着导电TiO_2含量的增加,导电母粒的电阻率逐渐下降,当TiO_2质量分数大于65%时,电阻率变化趋缓;当分散剂质量分数在1.0%左右时,导电TiO_2的颗粒分散情况较好,且体积电阻率也处于相对较低的水平。
PBT(polybutylene terephthalate) and conductive TiO_2 were used as raw materials, magnesium stearate was used as dispersant to prepare conductive masterbatch by melt blending. The effect of conductive TiO_2 content and dispersant content on the electrical properties and dispersion of conductive masterbatch were analyzed by SEM, TEM and high resistance meter etc. The results show that the content of conductive TiO_2 increases, the resistivity of the conductive masterbatch decreases, and the resistivity changes slowly when the conductive TiO_2 content is greater than 65%. The particle dispersion of conductive TiO_2 is better when the amount of dispersant is about 1.0% and the volume resistivity is also at a relatively low level.
