摘要
PURPOSE: A method for manufacturing a polyolefin-based micro-porous membrane is provided to obtain the superior porosity by including two or more low molecular organic compounds with different physical characteristics as a pore-forming agent.;CONSTITUTION: A polyolefin mixing resin, one or more hydrocarbon-based low molecular organic compounds, and a composition manufacture a polyolefin mixing solution. The polyolefin mixing solution is melted and pressed. The melted polyolefin mixing solution is solidified to form a casing sheet. The sheet is stretched to form a film, and pores are expanded. The hydrocarbon-based low molecular organic compounds are eliminated from the film, and the film is dried and heated.;COPYRIGHT KIPO 2011
