摘　　要：制备了以IR651和IR1700为引发剂的紫外光(UV)固化胶粘剂,研究其感光性能和粘接性能。在曝光30s后,以IR1700为引发体系的UV固化胶粘剂的剪切强度可达8.3MPa,而引发体系为IR651的剪切强度仅为0.6MPa。比较了两种光引发剂时的感光性能,IR1700体系的感度值为2.85mJ/cm^2,而IR651的为4.03mJ/cm^2。经深度固化研究表明,IR1700具有深度光固化的优异性能。IR651 and IR1700 photoinitiators were used to compose UV- curing polyurathane adhesives by 30 seconds of exposion to UV lights. Shear strength of UV-curing adhesive containing IR1700 and 1R65I were 8.3 and 0.6 MPa, respectively. Photosensitivity of the adhesives, obtained by the characteristic curves, were 2.85 and 4.03 mJ/cm2 for UV-curing adhesives containing IR1700 and IR651, respectively. It is concluded by the deep layer curing that IR1700 photoinitiators showed higher sensitivity than IR651 .
