摘　　要：自制了S2O28-/介孔氧化锆固体酸催化剂,并通过氮气吸附脱附、XRD、TG-DSC对其结构进行表征。该催化剂参与制备环氧脂肪酸甲酯增塑剂,产物的环氧值达4.55%,表观理化性质分析、FI-IR及1H-NMR组分分析均表明,催化环氧化的效果较好。在相同条件下,分别考察环氧脂肪酸甲酯、DOP、DOTP增塑的环氧树脂固化体系的力学性能,结果表明,环氧脂肪酸甲酯能赋予固化体系较佳的综合力学性能。The self-made solid acid catalyst has been prepared and characterized by nitrogen adsorption-desorption, XRD and TG-DSC. The epoxy value of epoxy fatty acid methyl ester catalyzed by the obtained solid acid catalyst is 4. 55% ,which also has good physical-chemical properties. Moreover, the results of FI-IR and ^1 H-NMR show that the catalytic effect is good. The mechanical properties of epoxy resin curing systems toughened by different plasticizers have been tested in the same conditions. The results show that better comprehensive mechanical properties of curing system can he given by the epoxy fatty acid methyl ester.
