摘要
以资源丰富的花生壳为原料,利用室温发泡方法制备了可降解生物质聚氨酯泡沫塑料。详细研究了花生壳用量、发泡剂以及泡沫稳定剂等对聚氨酯泡沫密度的影响;考察了花生壳含量对聚氨酯泡沫压缩强度的影响;利用土埋降解法,研究了生物质聚氨酯泡沫的降解行为。结果表明,当花生壳添加量为20%时,制备聚氨酯泡沫具有较低的密度(44kg·m-3)和较高的比压缩强度(2.4×103 N·m·kg-1)。另外,花生壳的加入,较大降低了聚氨酯泡沫的生产成本,具有良好的应用前景。
The biomass of polyurethane foam material was prepared via a step foaming method using abundant peanut shell as filler. Factors on the preparation of polyurethane foam including contents of peanut shell, foaming agent and foam stabilizer were studied in detail. The effect of content of peanut shells on the compressive strength of polyurethane foam is also discussed. Finally, degradation behaviors of the foams were studied using soil burial degradation method. The results showed that polyurethane foam containing 20% content of peanut shell display lower density（44 kg ·m^-3） and higher specific strength（2.4）〈 103 N · m· kg^-1）. In addition, the cost of production of polyurethane foam was greatly reduced when the peanut shell was added, which has good application prospect.
