The present invention relates to a method for producing a semi-IPN composite, the method including polymerizing a hydrophilic monofunctional acrylate (b1) and a polyfunctional acrylate (b2) in a solution of a polyurethane (A) prepared using an aromatic polyisocyanate as a raw material. The present invention also relates to a method for producing a moisture-permeable film that is obtained by drying the semi-IPN composite obtained by the above production method. One object of the present invention is to provide a method for producing a semi-IPN composite excellent in moisture permeability, water-swelling resistance, and stain resistance. The semi-INP composite obtained by the production method of the present invention is excellent in moisture permeability, water-swelling resistance, and stain resistance. Therefore, the semi-IPN composite can be preferably used for moisture-permeable waterproof fabrics for clothing, medical, and sanitary use and for skin and topcoat layers of synthetic leathers.
本发明涉及一种生产半 IPN 复合材料的方法,该方法包括在以芳香族多异氰酸酯为原料制备的聚氨酯(A)溶液中聚合亲水性单官能丙烯酸酯(b1)和多官能丙烯酸酯(b2)。本发明还涉及一种透湿薄膜的生产方法,该薄膜是通过干燥上述生产方法得到的半 IPN 复合材料而得到的。本发明的一个目的是提供一种生产透湿性、抗水膨胀性和抗污性极佳的半 IPN 复合材料的方法。通过本发明的生产方法获得的半 IPN 复合材料具有优异的透湿性、抗水膨胀性和抗污性。因此,半 IPN 复合材料可优先用于服装、医疗和卫生用透湿防水织物,以及合成皮革的表皮层和面层。
