| 摘 要： | 通过对不同泡沫密度、不同异氰酸酯指数的MDI基聚氨酯慢回弹泡沫进行舒适因子、温度敏感性、透气性、压力分布等测试，研究了MDI基聚氨酯慢回弹床垫泡沫的舒适性。结果表明，增加泡沫密度有利于提高慢回弹泡沫的舒适因子，也有利于减小慢回弹泡沫的温度敏感性；MDI基聚氨酯慢回弹泡沫在较宽的密度及异氰酸酯指数范围内具有良好的透气性，且压力分布均匀，舒适性较高。

| Abstract: | The comfortability of MDI-based viscoelastic PU foam by SAG, temperature sensitivity, breathability and pressure distribution measurement in different densities and isocyanate indexes was studied. The result showed that increasing density was conducive to increase the SAG of viscoelastic foam. Increasing density or reducing isocy- anate index was conducive to reduce the temperature sensibility of viscoelastic foam. The MDI-based viscoelastic PU foam which had good breathability could be used in wide density and index range. This kind of foam had uni- formity pressure distribution and good comfortability. |
