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。

Abstract

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.
