摘　　要：以聚丙烯(PP)无纺布为原料,摩擦电压为测量值,采用响应面分析法(RSM)探究了单体质量分数、光引发剂浓度和紫外光照时间对摩擦电压的影响,确定了抗静电改性的最优工艺:单体质量分数10.48%,光引发剂浓度0.051mol/L,紫外光照20.69min,摩擦电压最小为2255.16V。经最优工艺实验验证,改性后PP无纺布的摩擦电压为2200~2475V,表明响应面模型具有一定的可信度,能够有效预测实验各因素对摩擦电压的影响。Using polypropylene (PP) non-woven fabric as raw material and friction voltage as measured value, the effects of monomer mass fraction, photoinitiator concentration and ultraviolet irradiation time on friction voltage were investigated by response surface methodology (RSM). The optimum antistatic modification process was determined as follows: the mass fraction of monomer was 10.48%, the concentration of photoinitiator was 0.051 mol/L, the ultraviolet irradiation time was 20.69 min, and the minimum friction voltage was 2 255.16 V. The optimum technological conditions were verified by experiments. The friction voltage of modified PP non-woven fabric was 2 200~2 475 V. The results showed that the response surface model had certain reliability which could effectively predict the influence of various factors on the friction voltage.
