Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood by those skilled in the art, the present invention is further described with reference to the accompanying drawings and examples.
As shown in fig. 1, in some embodiments of the present invention, a super-tough cable includes a transmission core 10, a shielding layer 20, a middle quilt 30 and an outer quilt 40, wherein the transmission core 10 is disposed in the shielding layer 20, the middle quilt 30 covers the shielding layer 20, the outer quilt 40 covers the middle quilt 30, and the shielding layer 20 is woven by copper-plated Kevlar fibers.
In the embodiment, chemical plating is adopted to carry out surface copper plating treatment on Kevlar fiber, so that the Kevlar fiber has metal characteristics such as conductivity and the like, and the copper plated Kevlar fiber is obtained; it will be appreciated that in other embodiments, the copper-plated Kevlar fibers may also be obtained by surface copper plating Kevlar fibers by other methods such as vacuum plating.
In the embodiment, the copper-plated Kevlar fiber is obtained by performing surface copper plating treatment on the Kevlar fiber, and the shielding layer is made of the copper-plated Kevlar fiber instead of metal fiber, so that metal raw materials are saved, and the shielding layer is more environment-friendly; and the shielding layer made of copper-plated Kevlar fibers also has the characteristics of high strength, high modulus, acid and alkali corrosion resistance, light weight and the like, so that the cable has higher toughness, lighter weight and stronger tensile property.
In a preferred embodiment of the invention, a PVA (polyvinyl alcohol) coating layer is formed on the surface of the copper-plated Kevlar fiber after coating.
When in film covering, firstly, PVA is put into distilled water with the temperature of 95 ℃ for hydrolysis for 2 hours to obtain PVA solution, then the copper-plated Kevlar fiber is immersed into the PVA solution for film covering, and a PVA film covering layer is formed on the surface of the copper-plated Kevlar fiber, so that the PVA film-covered copper-plated Kevlar fiber is obtained. In this example, the concentration of the PVA solution was 5 g/L; in other embodiments, the concentration of the PVA solution may be 1g/L, 3g/L, 7g/L, or 10 g/L.
FIGS. 2-a and 2-b are surface topography maps of copper-plated Kevlar fiber and PVA coated copper-plated Kevlar fiber after bending peel test, respectively. It can be seen that when no film is coated, the large-scale peeling phenomenon occurs on the surface of the coating after the sample is bent, and the falling is obvious; after PVA film coating, the surface of the coating has only a few cracks and has no large-scale damage phenomenon.
FIG. 3 is a graph showing the change in surface unit resistance of copper plated Kevlar fibers and PVA coated copper plated Kevlar fibers, where it can be seen that the surface unit resistance of the copper plated Kevlar fibers is about 0.3 Ω/cm, indicating that the copper plating is relatively uniform and the conductivity is good; however, the unit resistance of the surface of the PVA coated copper-plated Kevlar fiber gradually increases with the increase of the hydrolysis concentration of PVA, but the hydrolysis concentration is less than 10g/L, the resistance change range is not large, and the PVA coated with the appropriate hydrolysis concentration has a certain protection effect on the coating and has little influence on the conductivity.
In this embodiment, the PVA coating is performed by copper-plated Kevlar fibers, and the PVA coating layer can protect the chemical plating layer of the Kevlar fibers under the condition that the conductivity of the plating layer is slightly affected, so that the chemical plating layer of the Kevlar fibers is prevented from being peeled off in large pieces, the integrity and durability of the chemical plating layer on the Kevlar fibers are enhanced, and the metal characteristics of the copper-plated Kevlar fibers are maintained for a long time.
In a preferred embodiment of the present invention, the transmission line core 10 includes a power line 11, a ground line 12 and two signal transmission lines 13. The structure and function of the power line 11 and the ground line 12 adopt the prior art, and are not described in detail herein; the signal transmission line 13 comprises a signal line shielding layer and a plurality of copper-plated Kevlar fibers arranged in the signal line shielding layer.
