This invention discloses a method for preparing a gas separation membrane, specifically a method for densifying and hydrophobically modifying the outer surface of a hollow fiber membrane. The invention primarily involves mixing isotactic polypropylene granules in a mixer and heating them to 150-200°C. The granules are then stretched and extruded into a membrane through a spinneret while in a molten state. The membrane is then cooled for 1-3 minutes in a cooling chamber using volatile alkanes or alcohols as atomizing cooling media. Finally, the hollow fiber membrane fibers are stretched and drawn onto rollers, automatically wound onto the rollers to form the original membrane fibers. These fibers are then subjected to post-treatment processes such as overnight soaking in deionized water and washing to obtain the hollow fiber degassing membrane. The advantages of this invention are that it eliminates the need for introducing other components (the alcohol solvent is fully evaporated without residue), avoids material compatibility and stability issues between different components, and provides a long-lasting and reliable hydrophobic enhancement effect.
