摘　　要：采用甲基丙烯酸对E51环氧树脂进行改性。通过控制甲基丙烯酸的用量与反应条件,制备出改性环氧树脂,改性率约为50%。并利用该改性环氧树脂制备出一系列UV固化胶黏剂。正交试验结果表明改性环氧树脂用量对UV胶剪切强度有显著影响,通过配方优化获得优化配方,并对制备的UV胶粘剂进行耐温性研究,研究结果表明该UV固化胶粘剂的最快分解温度为454.9℃,具有一定的热稳定性。Through controlling of reaction condition and the amount of methacrylic acid, the modified epoxy resin was successfully prepared and modified rate was about 50%. Using modified epoxy resin as one important component, a series of UV curing adhesives were prepared. The orthogonal experiment showed that the content of modified epoxy resin was the main factor influencing shear strength. The temperature tolerance research found that the UV curing adhesive fastest decomposition temperature was 454.9 ℃, which showed its thermal stability.
