Rising energy and raw material prices, dwindling resources, increased recycling, and the need for sustainable management have led to growth in the smart materials sector. In recent years, the importance and diversity of bio-based adhesives for industrial applications has grown steadily. This article focuses on the production and characterization of insulation panels consisting of peat moss and two bio-based adhesives. The panels were pressed with tannin and animal-based resins and compared to panels bonded with urea formaldehyde. The physical-mechanical properties, namely, thermal conductivity (TC), water vapor diffusion resistance, modulus of rupture (MOR), modulus of elasticity (MOE), internal bond (IB), compression resistance (CR), water absorption (WA) and thickness swelling (TS) were measured and analyzed. The results show that the insulation effectiveness and mechanical stability of moss panels bound with tannin and animal glue are comparable to standard adhesives used in the composite industry.
能源和原材料价格上涨、资源日益减少、回收利用增加以及可持续管理的需求推动了智能材料领域的发展。近年来,用于工业应用的生物基胶粘剂的重要性和多样性稳步增长。本文重点关注由泥炭藓和两种生物基胶粘剂组成的保温板的生产和特性。这些板材用单宁和动物基树脂压制,并与用脲醛树脂粘结的板材进行比较。测量并分析了其物理力学性能,即热导率(TC)、水蒸气扩散阻力、抗折强度(MOR)、弹性模量(MOE)、内结合强度(IB)、抗压强度(CR)、吸水率(WA)和厚度膨胀率(TS)。结果表明,用单宁和动物胶粘结的苔藓板的保温效果和机械稳定性与复合材料行业使用的标准胶粘剂相当。
