[0002] In fields such as building decoration, electronics and electrical appliances and transportation, double-sided tape is a key adhesive material that must simultaneously meet the requirements of high-strength bonding and fire safety performance. Existing double-sided tapes mainly consist of a flame-retardant layer added to the outside of the substrate layer for flame retardancy, and an adhesive layer set on the outside of the flame-retardant layer for bonding.

[0003] However, the flame retardant layer has a high surface smoothness and insufficient interfacial bonding with the adhesive layer. Especially in humid or vibrating environments, the adhesive layer and the flame retardant layer are prone to delamination, leading to bonding failure.

[0004] Therefore, how to improve the interfacial bonding force between the adhesive layer and the flame retardant layer through structural design, while maintaining the basic adhesive performance of the double-sided adhesive, has become a technical problem that urgently needs to be solved in this field.
