Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to a flame-retardant double-sided adhesive tape for automobiles. Background Art

[0002] Flame retardant double-sided automotive tape uses flame retardants and high-temperature flame retardant materials for interior fixing, bonding and sealing of automobiles, involving flame retardant properties, material selection and adhesion technology. Flame retardant properties ensure that flame propagation is suppressed in high-temperature environments, reducing the risk of fire. Material selection includes flame retardants and glass fibers, which provide high-temperature flame retardant properties. Superior bonding properties ensure a strong connection between different automotive materials such as plastics and metals. Together, these technologies ensure that flame retardant double-sided tape plays a key role in automotive manufacturing and improves overall safety.

[0003] The Chinese utility model with the publication number CN218951309U proposes a flame-retardant double-sided tape for vehicles, comprising a base layer, a reinforcement layer is provided on one side of the base layer, and an anti-ultraviolet layer is provided on the other side of the base layer, a flame-retardant layer is provided on the side of the reinforcement layer away from the base layer, an anti-static layer is provided on the side of the flame-retardant layer away from the reinforcement layer, an adhesive layer is provided on the side of the anti-static layer away from the flame-retardant layer and the side of the anti-ultraviolet layer away from the base layer, and a release layer is provided on the side of the two adhesive layers away from the base layer; the flame-retardant layer adopts a flame-retardant polyacrylate layer, and the interior of the flame-retardant layer is filled with a halogen-based flame-retardant particle layer. The utility model has strong flame retardancy, anti-ultraviolet and anti-static properties, and at the same time has strong structural strength, so that the tape is not easily damaged by pulling, thereby improving the practicality of the tape.

[0004] However, the above practicality still has shortcomings:

[0005] 1. The halogen-based flame-retardant particle layer in the utility model releases halogenated gases, generates flame-retardant gas phase reaction products, and exerts a flame-retardant effect. The main halogen elements involved include bromine and chlorine. Large-scale use will cause serious problems such as atmospheric emissions, water pollution, soil residues, biological enrichment, and ecosystem impacts.

[0006] 2. The utility model uses a polytetrafluoroethylene fiber layer as the base layer. Although this material has excellent properties such as high temperature resistance, corrosion resistance, and wear resistance, it is also extremely difficult to bond. The surface energy of polytetrafluoroethylene is extremely low, and it is difficult for a general adhesive layer to form a strong bond with it. Even if a special treatment method is used, it will increase the cost and complexity, and the bonding effect is also unstable. Utility Model Content
