化学官能团对地聚合物力学性能的影响研究

Effect of chemical functional groups on the mechanical properties of the geopolymer

选用带有不同有机官能团如羧基、羟基、氨基的几类低分子有机化合物:丙醇、丙胺、丙酸、丙酸钠,将它们与地聚合物进行反应,研究不同官能团对地聚合物力学性能的影响。结果表明:丙胺、丙酸、丙酸钠能使地聚合物的韧性得到改善,但不同低分子有机化合物改善效果有明显差异。不同掺量的丙胺、丙酸、丙酸钠对地聚合物进行增韧改性效果不同,它们有各自的最佳掺量。

Selection of different organic functional groups such as carboxyl,hydroxyl,amino several types of low molecular weight organic compounds,alcohol,propylamine,propionic acid,sodium propionate,they will react with the geopolymer to study the mechanical properties of different functional groups on the geopolymer.The results showed that propylamine,propionic acid,sodium propionate can make the toughness of polymer was improved,but there are obvious differences in the effect of improving on low molecular organic compound.Propylamine,propionic acid,sodium propionate different contents of different geopolymer toughening modification effect,they have their own optimal dosage.
