The invention discloses a thermosetting adhesive for an insulating film and a preparation process of the thermosetting adhesive. The thermosetting adhesive is prepared from macromolecular dihydric alcohol, a curing agent, a tackifier, a filler and an antioxidant according to a certain proportion and working procedures. According to the prepared adhesive, the raw material component proportion and the preparation technology are optimized, the preparation process is environmentally friendly and free of pollution, polyester films and the like are used as base materials, the base materials are hot-pressed on interface materials such as AL plates, nickel sheets and PA at a certain temperature, for a certain time and under a certain pressure, good insulation, flame retardance and weather resistance are achieved, and the adhesive can be widely applied to the field of adhesive materials. The adhesive property is stable under various conditions of high and low temperature, high temperature, high humidity and the like,
