摘要
目的通过研究沙柳纤维不同掺入量对材料性能的影响,得到性能更优的废纸纤维基轻质材料。方法采用机械发泡和化学发泡相结合的二次发泡法、水玻璃凝胶-溶胶法、硼系阻燃法和恒温鼓风干燥法制备废纸纤维基轻质材料,对样品进行密度和力学性能测试,利用氧指数、热重等测试分析手段,对材料结构和性能进行表征分析。结果沙柳纤维掺入量（质量分数）为40%~60%时,材料的密度约为16.52 kg/m3,抗压强度可达21 k Pa,回弹率可达60%以上,氧指数可达31.2%,热稳定性好,结构稳定。结论沙柳纤维的掺入量对材料的密度、抗压强度、压缩应变和阻燃性等性能均有影响。
In order to get low-density waste paper fiber-based material with better performance, the influence of Salix fiber dosage on the performance of the material was studied. The low-density waste paper fiber-based material was prepared by the secondary foaming method incorporating mechanical foaming method and chemical foaming method,waterglass sol-gel method, boron flame-retardant method, as well as constant temperature and blasting air drying method.The density and mechanical performance of the samples were tested, and the material structure and properties were characterized using test methods such as LOI and thermal gravimetric. When the Salix fiber incorporation（mass fraction）was 40%~60%, the density of the material was about 16.52 kg/m3, the compressive strength could reach 21 k Pa, the rebound rate could reach more than 60%, LOI could reach 31.2%, the material had good thermal stability and stable structure. The material density, compressive strength, compressive strain, flame resistance and other properties were all affected by the incorporation of Salix fiber.
