摘　　要：以聚烯烃类短切纤维为主要纤维原料的电池隔膜纸基,经过湿法抄造和热风干燥获得初始强度。将其在不同的工艺条件下进行热压,探讨了热压温度、热压压力和热压速度对聚烯烃类电池隔膜纸基物理性能的影响。实验结果表明:热压压力对透气度和厚度影响最大,热压温度对抗张强度和伸长率影响最大。较适宜的热压工艺条件为:热压温度129℃,热压压力9N/m m,热压速度1.5m/min,此时聚烯烃类电池隔膜纸基物理性能指标为透气率37.0mm/s,厚度115μm,抗张强度2.49k N/m,伸长率16.7%。For battery separator paper-base made of polyolein fiber, the initial strength was obtained with bot air drying, pressed in different hot press conditions. The effect of different temperature, pressure and speed in hot press process on the properties of battery separator paper-base was discussed. Experimental results showed that when the temperature of hot press is 129℃, the hot press 9N/mm, the speed of hot press 1.5m/min, the permeability of battery separator paper-base reaches to 37.0mm/s, thicknessll5gm, strength2.49 kN/m, and elongation 16.7%.
