the graphene oxide is formed by stacking a plurality of graphene oxide single-layer structures; and inert gas is filled between two adjacent monolithic layer structures.
Firstly, the graphene oxide filled with inert gas is added in PVC, and in the use process of an actual product, bubbles remained between the graphene oxide layers can play a good buffering effect, so that the overall flexibility of the product is enhanced, and the improvement of user experience is facilitated when a charging cable is actually dragged; in addition, after bubbles exist between graphene oxide layers, the electrical insulation distance between two adjacent graphene sheets is favorably increased, and insulation failure is avoided;
secondly, in the technical scheme, a proper amount of graphene oxide is added into the PVC resin matrix, and the D50 of the graphene oxide is controlled, so that the addition amount of the graphene oxide and the D50 meet the relationship, because if the addition amount of the graphene oxide is large, firstly, the graphene oxide has certain conductivity and is not beneficial to the electrical insulation requirement of the PVC material, and in addition, the excessive addition can also cause the agglomeration of the graphene oxide; if D50 is too large, it is likely to cause a local direct formation of a conductive path, and if D50 is too small, it is also likely to cause a problem of difficulty in dispersion; the inventor discovers that after the two satisfy the above relation, under this addition range and D50 condition, graphene oxide can be in the good dispersion of PVC material to after the dispersion, under the insulating effect assistance of PVC, have sufficient creepage distance between the adjacent graphene oxide granule, can guarantee to fill electric pile heavy current when charging, can not take place insulating inefficacy, guarantee safety during the actual research.

Further, the thermoplastic elastomer is selected from any one of SBS, SIS, SEBS or SEPS.
According to the technical scheme, the thermoplastic elastomer is added into the graphene oxide, so that the flexibility of a product is further improved by using the thermoplastic elastomer, and meanwhile, an electronic conducting path of the graphene oxide is changed, so that the electrical insulating property of the graphene oxide is further improved; in addition, thanks to the existence of the thermoplastic elastomer, the bubbles can be effectively trapped between the graphene oxide layers, and the product performance reduction caused by the overflow of the bubbles in the product processing and using processes is avoided.
Furthermore, the graphene oxide molecular structure comprises a conjugate region and an edge region, and the conjugate region in the graphene oxide molecular structure is grafted with octadecylamine.
Further, a surfactant is dispersed between two adjacent monolithic layer structures; the addition amount of the surfactant is 0.2-0.4% of the mass of the graphene oxide.
Further, the surfactant is selected from any one of a nonionic surfactant or an anionic surfactant; the nonionic surfactant is selected from any one of fatty alcohol-polyoxyethylene ether, alkylphenol ethoxylate, fatty acid-polyoxyethylene ester, polyoxyethylene alkylamine and polyoxyethylene alkylamide; the anionic surfactant is selected from any one of anionic polyacrylamide, sodium lignin sulfonate, sodium dodecyl benzene sulfonate and sodium stearate.
Further comprises microcrystalline wax accounting for 0.2-0.8% of the mass of the PVC resin.
Above-mentioned technical scheme is through introducing the microcrystalline wax of certain quality in the PVC resin, microcrystalline wax melting point is lower, in the product course of working, the melting can take place preferentially, and its melting back, can be with the same quality graphene oxide that is lighter relatively, especially inside is filled with gaseous graphene oxide and is carried, make its top layer that diffuses the PVC material, thus, receive dragging at the product, when ground friction, graphene oxide's existence, can promote the wear resistance of product, and, because graphene oxide is more at the top layer distribution on the top layer, when processing, the surface layer temperature is lower relatively, can effectively reduce gaseous overflow volume, and, graphene oxide is after the surface layer distribution, it is when the in-service use, increase with inside cable distance, the probability that the product takes place insulating failure further reduces.
