detailed description

In order to understand more clearly the above purpose, features and advantages of the utility model, the utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

In the following description, a lot of specific details have been set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways that are different from those described here. Therefore, the utility model is not limited to the specific details of the following disclosure EXAMPLE LIMITATIONS.

Embodiment 1, as shown in Figure 1, this embodiment provides a tensile graphene composite cable, including cores 1 arranged in clusters and twisted with each other, the number of cores 1 can be designed differently according to needs In this embodiment, there are 7 wire cores. In this embodiment, the wire core 1 is a copper core, and each wire core 1 is covered with a cladding layer 2. Specifically, the cladding layer The material of the cladding layer 2 is graphene. The choice of graphene for the cladding layer 2 mainly considers two aspects. One is that the melting temperature of graphene is high, and there will be no phenomenon of melting and falling off due to short-term overload and high temperature of the circuit. The second is graphite The presence of ethylene isolates the wire core from the insulating layer, which is convenient for installation.

In order to avoid mutual influence between the wire cores, an insulating layer 3 is sheathed on the cladding layer 2. In this embodiment, the material of the insulating layer 3 is a silane cross-linked polyethylene insulating layer, and the silane cross-linked polyethylene is used as the insulating layer 3 Mainly considering that silane cross-linked polyethylene has excellent heat resistance, and at the same time, the elongation rate is much higher than other materials, and the resistance to breakdown is also high.

The wire core is covered with a flame-retardant layer 4 for wrapping all the wire cores. The design of the flame-retardant layer 4 mainly considers that once an internal short circuit or external combustion occurs, it can avoid the occurrence of a fire. In this embodiment, the selected Flame-retardant modified polyethersulfone with excellent flame-retardant effect. Modified polyethersulfone has excellent anti-aging performance, so that it can be used at high temperature for a long time. In case of unavoidable fire, escape safely.

In order to further improve the performance of the cable, in this embodiment, a filler 5 is provided between the flame-retardant layer 4 and the insulating layer 3. Specifically, the filler 5 can be classified into flame-retardant powder or waterproof gypsum oil according to the usage. When the filler is flame retardant powder, it should be used in the flammable area; when it is waterproof gypsum oil, it should be used in the place with more water vapor.

In order to improve the tensile performance of the cable, in this embodiment, a tensile layer 6 is sheathed on the flame-retardant layer 4, and the tensile layer 6 can be a metal grid or a mesh of other materials. Among them, using the super toughness of graphene, the grid network composed of graphene fibers is selected as the tensile layer. Graphene has good elasticity, and the stretching range can reach 20% of its own size.

Considering that the cable provided by this implementation is mainly used in a highly corrosive environment, therefore, in this embodiment, double corrosion protection is provided. The first layer is the outermost outer jacket 8, and its main material is Graphene oxide is graphene oxide, which has good corrosion resistance and can effectively prevent cables from being corroded. At the same time, it can prolong the life of cables and enhance their mechanical strength.

The second layer of protection is the protective layer 7 arranged between the jacket 8 and the tensile layer 6. In order to improve corrosion resistance, the protective layer is made of TPU material, which is also called thermoplastic polyurethane elastomer. TPU has excellent high tension, With high tensile strength, toughness and aging resistance, it is a mature environmental protection material. At present, TPU has been widely used in medical and health care, electronic appliances, industry and sports, etc. It has the characteristics of high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance and weather resistance that cannot be compared with other plastic materials. At the same time, it has many excellent functions such as high waterproof and moisture permeability, windproof, cold proof, antibacterial, mildew proof, warm keeping, UV resistance and energy release. Through the cooperation of the jacket 8 and the protective layer 7, the corrosion resistance of the cable can be effectively improved, and the purpose of long-term use in a corrosive environment can be achieved.
