Abstract: This application discloses an insulation adhesive, an insulation tape, and an insulation adhesive preparation method. The insulation adhesive includes: an insulation colloid, and an insulation particle doped in the insulation colloid. Breakdown field strength of the insulation particle is greater than breakdown field strength of the insulation colloid. Since the breakdown field strength of the insulation particle is greater than the breakdown field strength of the insulation colloid, the insulation colloid is easier to break down than the insulation particle. When an electro-static discharge current acts on the insulation adhesive, the electro-static discharge current breaks down the insulation colloid that has worse insulation performance and that is easier to break down, and bypasses the insulation particle that has better insulation performance and that is more difficult to break down, so that a breakdown path of the electro-static discharge current becomes longer.
