Abstract The traditional binder used in mineral wool is phenolic resin that makes mineral wool insulations reliable and efficient. The toxicity and health hazards of phenol and formaldehyde are becoming more and more pressing, and the industrial production needs to focus on safer precursors. Several formulations of bio-based binders for mineral wool have been developed, meeting the challenge of performing equally well as conventional binders. Technical lignins, due to their intrinsic structure and their abundance, are good candidates for future industrial adhesives. Carbohydrates are other class of biomaterials widely used in both research and patent formulations toward mineral wool binders. Proteins and cardanol are still largely unknown precursors, although they have hidden potentials for reliable binder systems. Even if conventional binders are not replaced completely with bio-based alternatives today, a partial use is already a step forward in the right direction – toward future biorefinery-based industries and knowledge-based bioeconomies in general.

用于生产矿棉的木基树脂和其他生物基粘合剂

摘要 矿棉中使用的传统粘合剂是酚醛树脂，使矿棉绝缘材料可靠、高效。苯酚和甲醛的毒性和健康危害越来越紧迫，工业生产需要关注更安全的前体。已经开发了几种用于矿棉的生物基粘合剂配方，以应对与传统粘合剂性能相同的挑战。工业木质素由于其内在结构和丰富性，是未来工业粘合剂的良好候选者。碳水化合物是另一类生物材料，广泛用于矿棉粘合剂的研究和专利配方。蛋白质和腰果酚在很大程度上仍然是未知的前体，尽管它们具有可靠的粘合剂系统的潜力。
