摘要

研究了液体型有机氟添加剂(OFAs)对硬质聚氨酯(PU)和聚异氰脲酸酯(PIR)泡沫的形态、导热性和力学性能的影响。泡沫的形貌(密度、平均孔大小、各向异性比、开孔含量)、导热系数、压缩和弯曲性能都被表征。基于结果，我们观察到OFAs有效地减小了PU和PIR泡沫的平均细胞尺寸，从而改善了隔热和机械性能。

The effect of organofluorine additives on the morphology, thermal conductivity and mechanical properties of rigid polyurethane and polyisocyanurate foams

This study investigates the effect of liquid-type organofluorine additives (OFAs) on the morphology, thermal conductivity and mechanical properties of rigid polyurethane (PU) and polyisocyanurate (PIR) foams. Foams were characterized in terms of their morphology (density, average cell size, anisotropy ratio, open cell content), thermal conductivity and compressive as well as flexural properties. Based on the results, we observed that OFAs efficiently reduced the average cell size of both PU and PIR foams, leading to improved thermal insulating and mechanical properties.
