[0002] Graphene is a two-dimensional material with a monolayer thickness at the atomic level. Due to its high thermal conductivity and high electrical conductivity, it can be used as an excellent heating material. In a graphene heating wire, when an electric current is applied, it will generate resistance heating. Because of the good thermal conductivity of graphene, the heat energy can be quickly conducted to the surrounding environment during heating, thus achieving the effect of rapid heating. Graphene heating wires have a wide range of applications in many fields, such as medicine, construction, automobiles, etc. Generally speaking, the application prospect of graphene heating wires is very broad. Due to its advantages such as high efficiency, environmental friendliness, and safety, it will become an important development direction in the future heating field.

[0003] Deficiencies of the prior art: Although the existing graphene heating wires have good performance in terms of heating performance, there are still significant deficiencies in aspects such as waterproofing, moisture resistance, high temperature resistance, flame retardancy, rodent and insect prevention, and tensile strength. These shortcomings will be further amplified in some harsh usage environments, which will have a greater impact on their normal use. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an armored graphene heating wire to solve the problems existing in the above-mentioned background art.

[0005] The utility model provides the following technical solution: An armored graphene heating wire includes a graphene heating core. An outer layer of the graphene heating core is provided with a high-temperature resistant layer. An outer layer of the high-temperature resistant layer is provided with a flame retardant layer. An outer layer of the flame retardant layer is provided with an armored sheath. The armored sheath is provided with a mesh cloth, and an outer layer of the mesh cloth is provided with a PVC sheath.

[0006] Preferably, the high-temperature resistant layer is made of Teflon, and a water-blocking cable compound is filled between the high-temperature resistant layer and the graphene heating core.

[0007] Preferably, the flame retardant layer is made of flame retardant silica gel, and a fiberglass cloth is coated on the surface of the flame retardant layer.

[0008] Preferably, a rodent-proof agent is filled on the surface of the armored sheath, and the mesh cloth wraps and fixes the rodent-proof agent.

[0010] Technical effects and advantages of the utility model:

[0011] The outer layer of the graphene heating core of the present utility model is provided with a high-temperature resistant layer, the outer layer of the high-temperature resistant layer is provided with a flame retardant layer, the outer layer of the flame retardant layer is provided with an armored sheath, the armored sheath is provided with a mesh cloth, the outer layer of the mesh cloth is provided with a PVC sheath. The high-temperature resistant layer is made of Teflon material, which uses polytetrafluoroethylene as the matrix resin and then covers a fluorine coating on the surface of the matrix resin, having excellent high-temperature resistance and thermal stability. The flame retardant layer is made of flame retardant silica gel material, and a fiberglass cloth is coated on the surface of the flame retardant layer. The flame retardant silica gel material can decompose when heated at high temperature, and can absorb the heat on the surface of the combustible during the decomposition process to play a flame retardant role. At the same time, a large amount of water will be released to dilute the oxygen on the surface of the combustible. After the flame retardant silica gel material is coated with a fiberglass cloth, the anti-corrosion performance can be greatly improved. The surface of the armored sheath is filled with a rodent-proof agent, which can effectively prevent rats and insects from gnawing on the wire harness, avoiding damage to the wire harness caused by gnawing. The mesh cloth plays a role in wrapping and fixing the rodent-proof agent. The armored sheath has the effects of waterproofing and moisture-proofing. At the same time, the armored sheath and the mesh cloth cooperate with each other to further enhance the strength of the overall structure. The steel wire inserted into the PVC sheath can increase the strength, wear resistance and tensile performance of the PVC sheath. Description of the Drawings
