[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a high-sealing flame-retardant composite tape, such as Figure 1-Figure 2 As shown, it includes an aluminum foil film 1 and a main body layer 3. The inner side of the aluminum foil film 1 is coated with an upper flame retardant layer 2. The lower side of the aluminum foil film 1 is compounded on the upper side of the main body layer 3. The lower layer of the main body layer 3 is provided with a foam 4. The lower side of the foam 4 is coated with a lower flame retardant layer 5. The lower side of the lower flame retardant layer 5 is provided with a PVDF film 6. The lower side of the PVDF film 6 is provided with a release material 7. The aluminum foil film 1, as the outer layer of the tape, not only provides good reflection and heat insulation performance for the tape, but also helps to improve the overall sealing performance and effectively block the influence of the external environment on the internal structure of the tape. The upper flame retardant layer 2 coated on the inner side of the aluminum foil film can significantly improve the flame retardant performance of the tape and prevent the fire source from directly contacting and igniting the internal material of the tape. The main body layer 3, as the core structure of the tape, provides a stable support and connection function, ensuring the overall strength and stability of the tape. The foam 4 arranged on the lower layer of the main body layer 3 not only adds good elasticity and buffering performance to the tape, but also provides effective protection when it is squeezed by external force to prevent damage to the internal structure. The lower flame retardant layer 5 coated on the lower side of the foam 4 further enhances the flame retardant ability of the tape, and can effectively prevent the spread of fire even in the presence of flammable materials such as foam. At the same time, the PVDF film 6 disposed on the lower side of the lower flame retardant layer 5 has good weather resistance and chemical stability, and can protect the internal structure of the tape from corrosion by harsh environments and chemicals. The release material 7 on the lower side of the PVDF film 6 allows the tape to be easily peeled off during use, improving the convenience of use. At the same time, the release material 7 can also prevent the tape from sticking during storage and transportation, ensuring the quality and service life of the tape.

[0023] Furthermore, the upper flame retardant layer 2 and the lower flame retardant layer 5 both use solvent-based flame retardant adhesives or hot melt flame retardant adhesives with a thickness of 0.01-0.12 mm. The upper flame retardant layer 2 is mainly used to bond the aluminum foil film to the PE, PET or cotton-polyester material coated substrate. The glue has good flame retardancy and viscosity, can bond various materials, and has good fixation after bonding. The lower flame retardant layer 5 is mainly used to bond the PVDF film to the foam. The glue has good flame retardancy and viscosity, can bond various materials, and has good fixation after bonding.

[0024] Furthermore, the thickness of the foam 4 is 0.5-1 mm, and the foam 4 is centered in the middle of the adhesive tape. The material has good elasticity and can better seal the gaps at the mouths of some containers.
