摘要
将稻草经清洗、蒸汽爆破、粉碎等工艺处理后,在100℃条件下用离子液溶解稻草粉末,得到秸秆溶液,采用延流法制得了秸秆膜,并选用棉织物作增强基材,将制得的秸秆溶液与棉织物复合,冷却洗净,去除离子液后晾干,得到高气密性增强膜.分析了秸秆膜的化学成分,结果表明,其保留了原稻草秸秆的主要化学成分,且含量相差不大.还对增强膜与秸秆膜进行了表面形态、回潮率、透湿性能、透气性能、力学性能研究对比,研究结果表明,秸秆液在棉织物表面形成无界面致密膜,这种增强膜具有高气密性、强吸湿性、较好的力学性能.
This paper provides a method of using straw to prepare high airtight antimicrobial enhanced membrane. After cleaning, blasting and griding, dissolving the straw in the ionic liquid [bmim]C1 at 100℃, and combining the straw solution and cotton fabric, so a high airtight antibacterial enhanced membrane was obtained after washing and drying. The surface morphology, moisture-regaining, water vapor and air permeability and mechanical properties of the enhanced membrane were studied and compared with the original membrane. The results show that the straw liquid completely composites fabric surface to form a layer interface dense film; the tidied reinforced membrane has high air tightness, strong moisture absorption and good mechanical properties.
