The invention discloses an insulating impregnating resin for a drawing groove wedge. The insulating impregnating resin comprises the following components by weight: 100 parts of benzoxazine-imide resin, 30-45 parts of epoxy resin, 5-15 parts of an active diluent, 0.5-1 part of an initiator, 0.8-45 parts of a curing agent, and 0.1-1 part of a curing accelerator. The insulating impregnating resin for a drawing groove wedge provided in the invention has a high heat-resistant grade, good insulation property. And all mechanical strength is high, especially the thermal mechanical strength. The resin also has certain flame retardant effect and excellent comprehensive properties, thus being expected to be widely applied in drawing groove wedge products and other fields. And the insulating impregnating resin for a drawing groove wedge involved in the invention can be used through simple blending. The preparation method is simple, and the use cost is low.
