| 目的 为了高值化利用固体废弃物资源，以污水厂的污泥燃烧产物——生物质灰、废纸和废木屑为原料，采用热压工艺制备生物质复合包装板材。方法 考察原料配方、胶黏剂种类和热压温度对复合包装板材结构和性能的影响。结果 实验结果表明，环氧树脂为相对最佳的胶黏剂，当纸纤维、生物质灰、废弃木屑和环氧树脂的质量比为40∶30∶20∶10时，在4 MPa、180 ℃下热压20 min制备的复合板材的抗弯强度为11.20 MPa，抗压强度为12.79 MPa，满足《框架木箱》(GB/T 7284—2016)的要求。扫描电镜显示，所制备的生物质复合板材的表面纤维呈网状分布，生物质灰颗粒均匀地附着在纤维上。与普通木材相比，生物质复合板材具有良好的热稳定性。结论 添加质量分数为30%生物质灰制备的生物质复合板材满足国标要求，可应用于包装领域。该研究不仅可缓解木材短缺现状，还为废弃资源再利用和生物质灰的资源化处置提供了新的研究思路。 |

| The work aims to manufacture biomass composite packaging boards with biomass ash from sewage sludge combustion, waste paper fiber and waste wood chips through hot pressing to make high-valued use of the solid waste resources. The effects of raw material formula, adhesive type and hot pressing temperature on the structure and properties of composite packaging board were investigated. The results showed that epoxy resin was the best adhesive. When the mass ratio of paper fiber, biomass ash, waste wood chips and epoxy resin was 40∶30∶20∶10, the bending strength and compressive strength of the composite board prepared by hot pressing process at 4 MPa, 180 ℃ for 20 min were 11.20 MPa and 12.79 MPa, respectively, meeting the requirements of GB/T 7284-2016 Frame Wooden Box". SEM images showed that the biomass ash particles were uniformly attached to the fibers, and the fibers were distributed in a network on the surface of the biomass composite board. It had better thermal stability than ordinary wood. The biomass composite board prepared by adding 30 g biomass ash meets the requirements of national standards and can be used in packaging. This study can not only alleviate the shortage of wood, but also provide a new research idea for the reuse of waste resources and the resource disposal of biomass ash. |
