The invention discloses a screen bonding adhesive tape using butyl rubber damping foam as the base material, which comprises the following components in parts by weight: 90‑110 parts of butyl rubber, 140‑160 parts of toluene, 40‑60 parts of heptane, 20‑40 parts of terpene phenolic resin, 5‑15 parts of liquid polyisobutylene, 0.5‑2 parts of expandable microspheres, 0.5‑2 parts of insoluble sulfur, 1‑3 parts of thiuram vulcanization accelerator, 0.1‑1 part of antioxidant, 3‑6 parts of black color paste, 90‑110 parts of acrylate pressure-sensitive adhesive, 0.5‑2 parts of isocyanate crosslinking agent, and 0.1‑0.5 parts of silane coupling agent. Belonging to the technical field of screen bonding adhesive tapes, the product has a high damping coefficient and excellent energy absorption and shock absorption performance, and can improve the collision and drop resistance of bonded products. In addition, it does not require expensive equipment such as UV curing coaters and twin-screw extruders, and can be produced by conventional solvent-based coating machines, which effectively reduces production costs.
