双向拉伸聚四氟乙烯复合膜的性能研究

PTFE

摘　要:通过双向拉伸工艺制备聚四氟乙烯复合膜。SEM分析表明：与单向拉伸工艺相比，双向拉伸可以获得更高的孔隙率，较小的孔径和较高的孔隙率可以达到防水透湿性。实验结果表明：采用三水平、四因素正交设计，确定了最佳工艺条件：涂胶压力0．1MPa，干燥温度60℃，干燥时间10S，复合压力0．1MPa，得到水蒸汽透过率和剥离强度均较好的聚四氟乙烯复合膜产品。

Properties of Biaxial Stretching  PTFE Composite FilmSUN Xiao-qing, LUO Huang, HUANG Ping Beijing Plastics Research Institute,Beijing 100009 ,ChinaAbstract: PTFE composite film was prepared by biaxial stretching process. SEM analysis showed that biaxial stretching could get higher porosity compared with uniaxial stretching,the smaller pore size and higher porosity could meet the waterproof and permeability. The results indicated that the processing conditions, which were 0. 1 MPa coating pressure,60℃ drying temperature,lO s drying time and 0. 1 MPa composite pressure,could get the best properties of steam permeability and stripping.
Key words:biaxial stretching ; PTFE ; composite film ; waterproof; permeability
