聚醚多元醇对单组分聚氨酯泡沫填缝胶性能的影响

Study on the Effects of Polyether Polyol on the Properties of One-Packed Polyurethane Foam Sealant

研究了聚醚多元醇的官能度及相对分子质量对单组分聚氨酯泡沫填缝 (密封 )胶性能的影响。聚醚二醇和聚醚三醇复配使用 ,可制得综合性能良好的单组分聚氨酯泡沫胶体系。

The effects of functionality and molecular weight of polyether polyols on the properties of one component polyurethane foam sealant were studied. With the compounding of polyether glycol and triol, the foam sealant can get good allround properties.
