Bonding member and applications thereof

The invention discloses a bonding member (1) with a multi-layer structure. The bonding member is used to seal the pores in the vehicle parts. The bonding member (1) comprises a carrier film (2), a self-adhesive damping material (3), an anti-corrosion protective layer (5), which can be re-coated, a sliding layer, and an electrical insulation layer (4). The anti-corrosion protective layer (5) is applied on the surface, which is far away from the carrier film (2), of the damping material (3) and is composed of paint and/or film. The sliding layer is mixed in the paint. The electrical insulation layer (4) is arranged between the carrier film (2) and the damping material (3).
