▎ 摘　　要

NOVELTY - Heat-conducting insulating composite adhesive tape comprises a heat-conducting silicon rubber layer, a base material layer and a pressure-sensitive adhesive layer, which are orderly arranged from top to bottom. USE - The heat-conducting insulating composite adhesive tape is useful in the preparation of electrical device e.g. positive temperature coefficient (PTC) air conditioner of energy automobile, a solar inverter, an IGBT power chip, a 5G base station, and a 5G smart mobile phone (claimed). ADVANTAGE - The heat-conducting insulating composite adhesive tape: has excellent heat-conducting performance and excellent bonding strength and good break down resistant voltage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing heat-conducting insulating composite adhesive tape comprising coating the heatconducting silicon rubber on the base material, drying and coating pressure-sensitive adhesive on the other side of the base material, drying and curing to obtain the heat-conducting insulating composite tape.
