摘　　要：针对目前林木资源短缺、纸浆价格波动幅度大等问题,以废弃纸纤维和经过无害化处理的生物质颗粒物料为原料,采用层压成型的方式制备生物质纸包装材料,并探讨了生物质颗粒物料添加量、施胶剂用量、预压压力对生物质纸包装材料的机械性能影响。试验发现,施胶剂用量为3%时,生物质颗粒留着率可达85%;生物质原料添加量为40%、预压压力为1.0MPa时生物质纸包装材料的机械性能最佳,抗张指数可达21.70N·m·g-1,耐破指数可达2.110kPa·m2·g-1。扫描电镜结果显示,包覆之后的生物质颗粒附着在纤维表面及纤维间的连接部位,有利于增强纤维之间的连接,从而提高生物质纸包装材料的抗张指数和耐破指数。热稳定性能分析结果显示生物质颗粒的添加可在一定程度上降低生物质纸包装材料的失重速率,增加材料的热稳定性。Due to the existing shortage of forest resources and price fluctuations in pulp,waste paper fiber and harmless biomass granular materials were introduced as part of the raw material to prepare paper packaging materials by means of laminated process.The influences of granular biomass additive amount,sizing agent and prepress on the mechanical properties of the biomass paper packaging materials have been discussed.Results indicated that the retention rate of biomass materials can reach 85%while the accession of sizing agent is 3%.The mechanical properties of the biomass paper packaging material will be optimized when the accession of biomass granular materials is 40%and the prepress is 1.0 MPa,the tensile strength index reached 21.70 N·m·g-1,and the burst index reaches 2.110 kPa·m2·g-1.Scanning electron microscopy(SEM)results show that granular biomass wrapping the fibers and the joining between the fibers are the beneficial constituent enhancing connection between the fibers,subsequently the tensile strength and rupture strength indexes of the biomass paper packaging materials being improved.Thermogravimetric analysis(TGA)results indicated that the accession of granular biomass reduces the mass loss rate and increasesthe thermal stability of the biomass paper packaging materials.
