| 摘要:本研究以竹浆、玻璃纤维和双熔点聚对苯二甲酸乙二醇酯（PET）纤维为原料，采用湿法成形工艺制备多孔纤维基材，并通过浸渍法负载聚丙烯酸钠（PAAS）树脂，开发出一种新型纸基除湿材料。系统研究了纤维配比、热压时间及PAAS树脂留着量对材料结构与性能的影响。结果表明，按照竹浆、双熔点PET纤维、短切玻纤质量比=4∶3∶3进行抄造，92 ℃热压8 min，PAAS树脂留着量为140%时，所得纸基除湿材料综合性能最佳，其抗张指数为29.5 N·m/g，挺度为1.22 mN·m，耐破度为149 kPa；在30 ℃、相对湿度90%环境下的平衡吸湿率为76%，吸湿后纸基除湿材料的抗张指数、挺度、耐破度分别保持在7.44 N·m/g、0.70 mN·m、149 kPa，并表现出良好的低温放湿特性。经过50次吸放湿循环后，材料吸湿容量基本保持不变，显示出良好循环稳定性。 |
| Abstract:This study presented a novel paper-based desiccant material fabricated through a wet-forming process. A porous fibrous substrate was first prepared from bamboo pulp, glass fibers, and dual-melting-point polyethylene terephthalate (PET) fibers, and then impregnated with sodium polyacrylate (PAAS) resin. The effects of fiber composition, hot-pressing time, and PAAS retention on the material’s structure and properties were systematically investigated. Results showed that the optimal performance was achieved with a mass ratio of 4∶3∶3 for the dual-melting-point PET fibers, bamboo pulp, and chopped glass fibers, respectively, after hot-pressing at 92 ℃ for 8 min and with a resin retention of 140%, exhibited optimal overall performance. Its tensile index was 29.5 N·m/g, stiffness 1.22 mN·m, and burst strength 149 kPa. Under conditions of 30 ℃ and 90% relative humidity (RH), the equilibrium moisture absorption rate reached 76%. After moisture absorption, the tensile index, stiffness, and burst strength were maintained at 7.44 N·m/g, 0.70 mN·m, and 149 kPa, respectively, along with demonstrating good low-temperature moisture release characteristics. Remarkably, its moisture absorption capacity remained virtually unchanged over 50 absorption-desorption cycles, indicating exceptional cycling stability. |
