Description

Technical Field

[0001] The utility model relates to the technical field of mica tape wires, and specifically relates to a polyimide film mica tape wire. Background Technique

[0002] Mica tape, also known as fire-resistant mica tape, is made by a mica tape machine and is a fire-resistant insulating material. It can be classified by use into: mica tape for motors, mica tape for cables. By structure, it can be divided into: double-sided tape, single-sided tape, triple-composite tape, double-film tape, single-film tape, etc. The polyimide film has excellent heat resistance, so it is suitable for use in mica tape wires;

[0003] A patent with the authorized announcement number of "CN216032979U" discloses a polyimide film mica tape wire, including mica tape. An antioxidant film is arranged inside the mica tape. A fiberglass cloth is laid at the bottom of the antioxidant film. A non-carbon film is adhered to the bottom of the fiberglass cloth. A polyimide film is adhered to the bottom of the non-carbon film. A winding drum is installed inside the mica tape, effectively solving the problem that the traditional mica tape is prone to oxidation during use, resulting in a short service life of the mica tape. The setting of the antioxidant film can effectively delay the oxidation time of the mica tape and effectively extend the service life of the mica tape. At the same time, the setting of the scratch-proof film can reduce the damage caused by the outside to the materials inside the mica tape and effectively extend the service life of the mica tape. The fiberglass cloth has strong tensile strength, effectively preventing the mica tape from cracking, and the mica tape has a reinforcement effect. Static electricity does not accumulate on the surface;

[0004] However, the following deficiencies exist in this device:

[0005] The surface wear resistance of the above device is poor, resulting in easy damage of the mica tape wire due to wear during use, and its strength is insufficient, prone to tearing, reducing the service life of the mica tape wire. Content of the Utility Model

[0006] The purpose of the utility model is to provide a polyimide film mica tape wire to solve the problems presented in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A polyimide film mica tape wire, including mica tape and a winding drum. The mica tape is wound around the outside of the winding drum. Mica flakes are arranged inside the mica tape. A polyimide film is arranged at the bottom of the mica flakes. An adhesive layer is arranged at the bottom of the polyimide film. A fiberglass layer is arranged at the top of the mica flakes. An anti-tear tape is arranged inside the fiberglass layer. A polyvinyl chloride film is arranged at the top of the fiberglass layer. A coating layer is arranged at the top of the polyvinyl chloride film.

[0008] Preferably, the tear-resistant tape is made of nylon fiber material, which has strong toughness and can improve the strength of the glass fiber layer.

[0009] Preferably, the tear-resistant tape is distributed in an S-shape on the inner side of the glass fiber layer and can be evenly distributed in the glass fiber layer to improve its strength performance.

[0010] Preferably, the coating layer is made of Teflon coating, which has high wear resistance and can improve the wear resistance of the mica tape.

[0011] Preferably, the material of the adhesive layer is silicone resin, which is a thermosetting polysiloxane polymer with a highly cross-linked structure, having the dual characteristics of organic resin and inorganic material, unique physical and chemical properties, good electrical insulation properties, and heat resistance and waterproof effects.

[0012] Compared with the prior art, the beneficial effect of the utility model is that the polyimide film mica tape line cooperates with the mica sheet, polyimide film, viscose layer, glass fiber layer, tear-resistant tape, polyvinyl chloride film and coating layer, so that when the mica tape is in use, by spraying the coating layer on the outer side of the polyvinyl chloride film, the material properties of both are utilized to greatly improve the wear resistance of the mica tape and reduce its wear rate. At the same time, the tear-resistant tape distributed in an S shape inside the glass fiber layer can enhance the toughness and tear resistance of the glass fiber layer, so that the strength of the mica tape is improved, tearing is not easy to occur, and the service life of the mica tape is extended.
