| 中文摘要: |
| 以稻草纤维为主要原料，采用稻草粒（粗）与细稻草纤维相混合，以聚乙烯醇、脲醛、淀粉为粘合剂，采用2段加压加热成型工艺，研究了成型工艺条件对稻草纤维材料性能的影响。研究表明，第1段成型压力、温度和时间对材料的性能有较大的影响；提高成型压力、温度和时间虽然可以提高材料的强度，但会降低材料的缓冲性能，而压力和时间不足也会降低材料的强度；较适宜的成型压力为 40～50 kPa, 温度为150～175 ℃，成型时间为6～10 min。 |
| 英文摘要: |
| Straw fiber-material was prepared using mixture of particles and acerose straw fiber as raw material, mixture of polyvinyl alcohol (PVA), urea-formaldehyde resin (UF), and starch as bond, with two stages pressing and heating processes. The influence of molding technology on physical and mechanical properties of straw fiber-material was studied. Result showed that molding pressure, molding temperature and molding time in the first stage have great influence on compressive stress and cushioning propriety of the material; increasing molding pressure, temperature, and molding time can enhance the strength, but reduce the cushioning performance of the material; lacking of molding pressure and molding time can also reduce the strength of the material; the appropriate molding pressure is 40～50 kPa, molding temperature is 150～175 ℃, and molding time 6～10 min. |
