The invention belongs to the technical field of adhesive agents, and particularly relates to a UV/thermal dual-curing adhesive agent and a preparation method thereof. Polyurethane modified alicyclic epoxy resin contained in the adhesive agent has good flexibility, is free of precipitation, has good compatibility with other resin, and has relatively high adhesion strength with different materials.The prepared UV/thermal dual-curing adhesive agent has the characteristics of low curing shrinkage rate, low expansion coefficient and no precipitation. More importantly, the adhesive agent disclosedby the invention has a UV and thermal quick dual-curing characteristic, can be subjected to rapid curing at the lower temperature of 80 DEG C at a place where ultraviolet light cannot irradiate afterbeing subjected to ultraviolet radiation curing and fixation, and is particularly suitable for being applied to VCMs (voice coil motors). A synthesis technology of the adhesive agent is simple and easy to operate, the cost is l
