为了改善热镀铝锌钢板表面耐指纹涂层的耐磨与加工成型性能,在其耐指纹处理剂中添加了不同粒径的聚四氟蜡制备涂层,研究了不同聚四氟蜡粒径时涂层的疏水性能,并利用表面性能分析仪和拉延设备考察了在室温及高温(100℃)下不同粒径聚四氟蜡时热镀铝锌耐指纹钢板的表面动摩擦系数和加工成型性能,并用三维视频显微镜分析了耐指纹钢板表面划痕形貌及深度.结果表明:在室温及高温下,聚四氟蜡的加入能够降低耐指纹钢板表面的动摩擦系数,还能提高耐指纹钢板表面的抗磨损性和加工成型性;聚四氟蜡的粒径对耐指纹钢板表面性能有较大影响,室温下随着聚四氟蜡粒径的增加,耐指纹钢板表面的动摩擦系数增大,抗磨损性和加工成型性逐渐降低;高温下当聚四氟蜡粒径增至一定后继续增加时,耐指纹钢板表面性能的变化趋势与室温时的一致.
