Zusammenfassung:The invention relates to a breathable waterproof membrane, which is prepared by spinning and processing an electrospinning liquid, wherein the electrospinning liquid comprises a first additive and a second additive. The first additive comprises a nylon copolymer and a first alcohol solvent. The second additive is prepared by reacting a composition in a second alcohol solvent, the composition comprises polysiloxy glycol, dihydric alcohol and isocyanate, and the dihydric alcohol comprises alkyl glycol, polyester glycol or a combination thereof. The breathable waterproof film of the present disclosure has high breathability, high waterproofness, and high flexibility. 一种透气防水膜由电纺液纺丝并加工而制得,且电纺液包括第一添加剂及第二添加剂。第一添加剂包括尼龙共聚物及第一醇类溶剂。第二添加剂由组成物于第二醇类溶剂中反应而制得,其中组成物包括聚硅氧二醇、二元醇及异氰酸酯,且二元醇包括烷基二醇、聚酯二醇或其组合。本公开内容的透气防水膜兼具高透气性、高防水性以及高柔软性。
