具有防水透湿功能的框架增强气凝胶保暖材料及其制备
摘要：
本发明提供了一种具有防水透湿功能的框架增强气凝胶保暖材料及其制备方法。该具有防水透湿功能的框架增强气凝胶保暖材料，其特征在于，包括至少一层防水透湿膜和至少一层三维多孔框架增强纤维气凝胶材料。所得保暖材料兼具有防水透湿功能及高孔隙率、小孔径特点，有效降低了空气的对流作用，提高该材料的保暖性能及服用舒适性，使其导热系数可达0.015～0.023W/(m·k)，同时在纤维气凝胶材料内部引入的三维多孔框架结构，提高了气凝胶材料的力学性能，其拉伸强度可达20～50kPa，扩宽了该保暖材料在保暖领域的应用范围。
摘要（英）：

A framework-reinforced aerogel warm-keeping material having waterproof and moisture permeable functions and preparation thereof are provided. The warm-keeping material is characterized by including at least one layer of waterproof and moisture permeable film and at least one layer of three-dimensional porous framework-reinforced fiber aerogel material. The warm-keeping material has the waterproof and moisture permeable functions and characteristics of high porosity and a small pore diameter, effectively reduces air convection, and improves warm-keeping performance and wearing comfort of the warm-keeping material. The heat conductivity coefficient of the warm-keeping material can be 0.015-0.023 W/(m.k). In addition, a three-dimensional porous framework structure introduced to the inside of the fiber aerogel material improves the mechanical performance of the aerogel material. The tensile strength of the warm-keeping material can be 20-50 kPa. The range of application of the warm-keeping material in the warm-keeping field is broadened.
