摘　　要：以缩二脲改性的环氧树脂为粘胶剂,玉米秸秆纤维为增强材料,多异氰酸酯为相容剂,丁基缩水甘油醚为稀释剂制备玉米秸秆纤维/环氧树脂复合材料。利用FTIR对其进行结构分析,万能试验机进行力学分析,并研究了玉米秸秆纤维用量对复合材料力学性能和耐水性的影响。结果表明,当粘胶剂质量分数为15%,相容剂与秸秆纤维质量比为1∶3时所制备的复合材料具有良好的力学性能,厚度溶胀率和吸水率较低,是一种性能较为优良的新型环保型复合材料。Abstract：Epoxy resin as adhesives was modified by biuret, corn stalks fiber for reinforcements, multi-isocyanate for eompatilizer, butyl ether as diluent to prepare corn stalk/epoxy composite material. Using FTIR analyzed its structure, the mechanics was analyzed by universal tester, and studied the amount of corn stalk impact on the mechanical properties and water resistance of composite material. The results showed that： when adhesives content is 15%, compatilizer corn stalks fiber rate is 1 ： 3, the composite material have good mechanical properties,low thickness swelling rate and water absorption, it is a new type environment friendly composite materials.
