摘　　要：采用不同羟值的聚醚多元醇改性酚醛树脂(PR)发泡材料,通过红外光谱(FT-IR)和动态流变测试研究聚醚多元醇对PR的结构及复合黏度的影响,扫描电镜(SEM)和压缩性能测试研究聚醚多元醇对酚醛泡沫(PF)的泡孔结构及压缩性能的影响。结果表明,聚醚多元醇可与PR形成化学键影响树脂的交联结构,加入聚醚多元醇CHE-204的PR具有较低的复合黏度,有利于产生均一的小泡孔,表现出较优的力学性能。The phenolic foams modified by different polyether polyol with different hydroxyl value were prepared. Then,the effect of polyether polyol on the chemical bond and complex viscosity of phenolic resin were studied though FT- IR and dynamic rheology test, as well as the effect of polyether polyol on the cell structure and compression property of phenolic foam though SEM photos and compression test. The results showed that the new chemical bond between the poly- ether polyol and phenolic resin increasing the crosslinking degree. The phenolic foam modified by CHE 204 showed the low- er complex viscosity, which contributed to the more uniform cell distribution and smaller cell size. Meanwhile, the phenolic foam modified by CHE-204 represented the superior mechanical property.
