| 英文摘要 | Two novel phosphorus-containing mannich-type bases, [(2-{[(diethoxy-phosphoryl)-phenyl-methyl]-amino}-ethylamino)-phenyl-methyl]-phosphonic acid diethyl ester (peda) and ({2-[2-(2-{[(diethoxy-phosphoryl)-phenyl-methyl]-amino}-ethylamino)-ethylamino]-ethylamino}-phenyl-methyl)-phosphonic acid diethyl ester (ptta) were prepared and employed as curing agents in an attempt to prepare flame retardant epoxy systems. through a curing reaction, phosphorus was incorporated in the backbone of the epoxy polymer. the processing characteristic of these systems was studied in terms of gel time at different temperatures. thermal and flame retardancy properties of the cured epoxy thermosets were characterized by differential scanning calorimetry (dsc), thermogravimetric analysis (tga), and flammability test. the degradation activation energy was calculated by kissinger's model. the results showed that the gel time of the phosphorus-containing epoxy systems was prolonged; the glass transition temperature (t(g)) was increased due to the introduction of phosphorus and the initial degradation activation energy of phosphorus-containing epoxy systems was lower than phosphorus-free epoxy systems. high char yield (23-27 wt%) and limiting oxygen index (loi) values of 28-30 were observed for the phosphorus-containing epoxy thermosets, indicating their improvement in flame retardancy. copyright (c) 2008 john wiley & sons, ltd. |
