Description

Technical Field

[0001] The utility model relates to the technical field of insulating tapes, in particular to a PET insulating tape with good flame retardant effect. Background Art

[0002] PET insulating tape is a widely used electrical material, composed of film and adhesive, with excellent insulation properties. PET insulating tape is widely used in electrical, electronic, communication, automotive, aerospace and other fields. It is used for insulation wrapping of wires and cables, fixation and protection of electronic components, insulation treatment of transformers and motors and other equipment, etc.

[0003] Patent document CN218404033U discloses a PET halogen-free flame-retardant insulating tape, which discloses "including a PET substrate, a first wear-resistant protective layer, a second wear-resistant protective layer, a flame-retardant coating layer, an insulating layer, and a pressure-sensitive adhesive layer, wherein the first wear-resistant protective layer is fixedly connected to the upper side wall of the PET substrate, the second wear-resistant protective layer is fixedly connected to the lower side wall of the PET substrate, the flame-retardant coating layer is fixedly connected to the side wall of the second wear-resistant protective layer away from the PET substrate, and the insulating layer is fixedly connected to the side wall of the flame-retardant coating layer away from the second wear-resistant protective layer. The utility model can improve the wear resistance and puncture resistance of the insulating tape when using the insulating tape, and avoid the phenomenon that the metal wire inside the wire will pierce the insulating tape when the insulating tape is used to protect the wire, causing leakage, and also improves the anti-friction ability of the outermost side of the insulating tape to avoid damage to the insulating tape caused by friction."

[0004] However, the PET halogen-free flame-retardant insulating tape disclosed in the above-mentioned document mainly considers improving the anti-friction ability of the outermost side of the insulating tape to avoid damage of the insulating tape due to friction, but it is not convenient to improve the multiple properties of the PET insulating tape body.

[0005] In view of this, it is necessary to develop a multilayer structure so as to improve the performance of the PET insulating tape body. Utility Model Content

[0006] The utility model aims to provide a PET insulating tape with good flame retardant effect, so as to solve the technical problem of improving the multiple performances of the PET insulating tape proposed in the above background technology.

[0007] To achieve the above object, the utility model provides the following technical solution: a PET insulating tape with good flame retardant effect, comprising: a PET insulating tape body, the inner wall of the PET insulating tape body is provided with a multi-layer structure, and the multi-layer structure is used to improve the performance of the PET insulating tape body;

[0008] The multi-layer structure includes a wear-resistant layer, which is arranged on the outer wall of the PET insulating tape body, a waterproof layer is installed on the inner wall of the PET insulating tape body, a flame-retardant layer is installed below the waterproof layer, a corrosion-resistant layer is installed on the inner wall of the PET insulating tape body, and the flame-retardant layer is located above the corrosion-resistant layer, and an anti-leakage protection layer is installed on the inner wall of the PET insulating tape body.

[0009] Preferably, an adhesive layer is installed on the outer wall of the PET insulating tape body.

[0010] Preferably, a replacement mechanism is provided at the bottom of the PET insulating tape body, and the replacement mechanism is used to replace the adhesive layer.

[0011] Preferably, the replacement mechanism comprises a double-sided adhesive block, and the double-sided adhesive block is located at the bottom of the PET insulating tape body.

[0012] Preferably, a replacement layer is installed at one end of the double-sided adhesive block, and one end of the replacement layer is fixedly connected to the adhesive layer.

[0013] Preferably, an anti-scratch film is installed on the outer wall of the adhesive layer.

[0014] Preferably, an adsorption adhesive layer is installed on the outer wall of the anti-scratch film, and a luminous strip is installed on the outer wall of the PET insulating tape body.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model improves the performance of the PET insulating tape body by installing a multi-layer structure. The multi-layer structure on the PET insulating tape body is used to improve the waterproof, flame retardant, corrosion and leakage performance of the PET insulating tape body. When producing the PET insulating tape body, a waterproof layer, a flame retardant layer, a corrosion resistant layer and an anti-leakage protection layer are arranged inside the PET insulating tape body. The material of the waterproof layer is a polyurethane material, which can improve the waterproof performance of the PET insulating tape body. The material of the wear-resistant layer is polyimide, which can improve the wear resistance of the PET insulating tape body and avoid the situation where the PET insulating tape body is damaged due to external friction. The material of the flame retardant layer is made of a halogen flame retardant, which improves the flame retardant function of the PET insulating tape body. The material of the corrosion resistant layer is polytetrafluoroethylene, and the material of the anti-leakage protection layer is polyethylene, thereby improving the waterproof, flame retardant, corrosion and leakage resistance of the PET insulating tape body and improving the diversity of the PET insulating tape body.

[0017] 2. The utility model is equipped with a replacement mechanism for replacing the adhesive layer. When the existing adhesive layer falls on the ground and is contaminated with dust, the PET insulating tape body of this section cannot be used, resulting in waste of the PET insulating tape body. Therefore, it is necessary to improve this so that the adhesive layer can be replaced. First, the original adhesive layer is changed to a double-sided adhesive block for installation, and the double-sided adhesive block is adsorbed on the bottom of the PET insulating tape body, so that the replacement layer and the adhesive layer are installed on the bottom of the PET insulating tape body, and then the anti-rubbing film is pulled to remove the adsorbed adhesive layer from the adhesive layer. The anti-rubbing film is used to protect the adhesive layer. Then, the PET insulating tape body is wrapped around the outside of the wire body by the adhesive layer. When replacement is required, the double-sided adhesive block can be directly removed from the bottom of the PET insulating tape body for replacement, thereby reducing the waste of the PET insulating tape body.
