| 摘要:本研究以竹浆纤维、微纤化纤维素（MFC）以及改性的无机填料凹凸棒（ATP）为原料，采用水系发泡和常压干燥技术，通过化学气相沉积法改性，制备了具有良好力学性能和隔热阻燃性能的疏水纤维素基泡沫材料。结果表明，随着改性ATP含量的增加，纤维素基泡沫材料的表面粗糙度提高，力学性能增强，当改性ATP含量达到80%时，纤维素基泡沫材料的压缩强度为186.01 kPa，弹性模量达93.44 kPa。此时，该纤维素基泡沫材料还展现出优异的阻燃和隔热性能，泡沫燃烧60 s后质量损失率为4.31%，且在150 ℃下加热30 min后，泡沫顶部与加热台温差达106.2 ℃，热导率为37.06 kW/(m·K)。此外，经化学气相沉积法改性后的纤维素基泡沫材料，具有较好的疏水性，其表面和内部水接触角分别为134.8°和132.5°，具有优异的疏水性和自清洁性能。 |
| Abstract:In this study， bamboo pulp fiber and micro-fibrillated cellulose (MFC)， and modified attapulgite (ATP) were used as raw materials to fabricate a hydrophobic， flame retardant cellulose-based foam materials with excellent mechanical properties and thermal insulation through aqueous foaming and atmospheric drying techniques， combined with the method of chemical vapor deposition. The results showed that increasing the modified ATP content， the surface roughness and mechanical properties of cellulose-based foam material were improved. At an optimal modified ATP content of 80%， the cellulose-based foam material achieved a compressive strength of 186.01 kPa and an elastic modulus of 93.44 kPa. At the same time， this cellulose-based foam material also demonstrated excellent flame retardant and thermal insulation properties. After 60 s of combustion， the mass loss rate of cellulose-based foam material was 4.31%. Following 30 min of heating at 150 ℃， the temperature difference between the top of the cellulose-based foam material and the heating platform reached 106.2 ℃， with a thermal conductivity of 37.06 kW/(m·K). Moreover， the cellulose-based foam material modified by chemical vapor deposition method demonstrated remarkable hydrophobicity， with water contact angles of 134.8°(surface) and 132.5°(internal)， possessed excellent hydrophobicity and self-cleaning capability. |
