Abstract

This study presents the development of boron-doped lignin-based composites reinforced with textile waste as a sustainable alternative to conventional insulation materials. By utilizing lignin, a byproduct of the paper industry, and textile waste from cotton and polyester blends, composites with varying boron concentrations (0 %, 5 %, and 10 %) were fabricated, evaluated for their thermal, acoustic, and fire-resistant properties. Among the samples, alb10 (10 % boron addition to pink cotton/polyester waste) exhibited exceptional performance, achieving a burning speed of 20 mm·s⁻¹, a significant reduction compared to 160 mm·s⁻¹ in the non-doped alb0 and a thermal conductivity of 0.04 W·mK⁻¹, comparable to commercial insulation materials. Compared to the reference material yltm (commercial felt), alb10 demonstrated superior fire resistance, enhanced thermal regulation, and improved acoustic insulation, underscoring boron's critical role as a flame-retardant additive. This work highlights the potential of boron-doped lignin-textile composites to address energy efficiency, fire safety, and waste management challenges, aligning with circular economy principles and offering a cost-effective, eco-friendly solution for future insulation applications.

硼掺杂木质素基复合材料，将纺织废料转化为高性能、可持续的绝缘材料硼掺杂木质素基复合材料，将纺织废料转化为可持续、高性能的绝缘材料

本研究提出了以纺织废料为增强材料的掺硼木质素基复合材料的发展，作为传统保温材料的可持续替代品。通过利用木质素，造纸工业的副产品，以及棉花和聚酯混合物的纺织废料，合成了不同硼浓度（0%，5%和10%）的复合材料，并对其热，声学和耐火性能进行了评估。在样品中，alb10（在粉色棉/聚酯废料中添加10%硼）表现出优异的性能，燃烧速度为20 mm·s−1，与未掺杂alb0的160 mm·s−1相比显著降低，导热系数为0.04 W·mK−1，与商业绝缘材料相当。与参考材料yltm（商用毛毡）相比，alb10表现出更强的耐火性、更强的热调节能力和更好的隔音性能，强调了硼作为阻燃添加剂的关键作用。这项工作突出了硼掺杂木质素-纺织复合材料在解决能源效率、消防安全和废物管理挑战方面的潜力，符合循环经济原则，并为未来的绝缘应用提供了一种具有成本效益、环保的解决方案。

期刊介绍： Materialwissenschaft und Werkstofftechnik provides fundamental and practical information for those concerned with materials development, manufacture, and testing. Both technical and economic aspects are taken into consideration in order to facilitate choice of the material that best suits the purpose at hand. Review articles summarize new developments and offer fresh insight into the various aspects of the discipline. Recent results regarding material selection, use and testing are described in original articles, which also deal with failure treatment and investigation. Abstracts of new publications from other journals as well as lectures presented at meetings and reports about forthcoming events round off the journal.
