摘要/Abstract

摘要： 采用异氰酸酯、聚酯多元醇、发泡剂（水）等原料通过一体发泡成型技术制备出一种新型的三明治泡沫夹心复合材料。利用热重分析、扫描电子显微镜等对不同水含量（质量分数分别为0、0.5 %和1.0 %）的硬质聚氨酯泡沫材料的泡孔直径、密度、热导率、压缩性能、三点弯曲和热力学性能等做了研究，进而确定提高硬质聚氨酯性能的最佳工艺。结果表明，随着水含量的增加，硬质聚氨酯泡沫材料泡孔直径增大，密度变小，热导率降低，保温性能提高，而压缩性能和三点弯曲却呈下降趋势；综合考虑硬质聚氨酯泡沫材料泡孔结构和良好的保温隔热及弯曲等力学性能，其最佳含水量为0.5 %。

Abstract: A new type of sandwich foam composite was prepared by an integrated foaming-molding method using isocyanate and polyester polyol as raw materials and distilled water as a foaming agent. The pore diameter, density, thermal conductivity, thermal properties, and compression and three point bending performance were investigated for the rigid polyurethane foam with water contents of 0, 0.5 wt % and 1.0 wt % by means of thermogravimetric analysis and scanning electron microscopy. The optimum parameters were then achieved. The results indicated that the pore diameter and thermal insulation performance of rigid polyurethane foams increased with an increase of water content, but their foam density and thermal conductivity decreased. However, the compression and three-point bending performance of the foams exhibited a decline trend. Therefore, to achieve the reasonable cell structure and good mechanical properties for the foams, the optimum moisture content should be determined as 0.5 wt %.
