▎ 摘　　要

NOVELTY - A semi-conductive shielded graphene coating is prepared using 18-43 %mass graphite raw material, 55-80 %mass adhesive, 0.5-1 %mass dispersant and 0.5-1 %mass stabilizer. The graphite raw materials are scaly graphite, expanded graphite, high orientation graphite, pyrolytic graphite and/or oxidized graphite. The binder is alkyd resin, urethane resin, polypropylene ester, acrylic resin and/or phenolic resin. The dispersant is sodium dodecyl sulfate, sodium dodecylbenzenesulfonate, polyvinylpyrrolidone, and/or 1-pyridine acid. USE - Semi-conductive shielded graphene coating is used for aerogenerator cable. ADVANTAGE - The semi-conductive shielded graphene coating has high adhesiveness, filming and isolation property, shielding property, and is prepared efficiently and economically by simple method with high yield without affecting the environment. DETAILED DESCRIPTION - A semi-conductive shielded graphene coating is prepared using 18-43 %mass graphite raw material, 55-80 %mass adhesive, 0.5-1 %mass dispersant and 0.5-1 %mass stabilizer. The graphite raw materials are scaly graphite, expanded graphite, high orientation graphite, pyrolytic graphite and/or oxidized graphite. The binder is alkyd resin, urethane resin, polypropylene ester, acrylic resin and/or phenolic resin. The dispersant is sodium dodecyl sulfate, sodium dodecylbenzenesulfonate, polyvinylpyrrolidone, and/or 1-pyridine acid. The stabilizer is pentaerythritol, talc, monoglycerol stearate, glycerol and/or ethylenediamine. Graphite raw materials, dispersant and cementing agent are added to a high-speed mixer, mixed at 600-1200 rpm for 10-25 minutes, and premix is obtained. The obtained premix is added to a screw extruder provided with a primary crushing section, a shear thinning section, a dispersed orientation section from the feed end to the discharge end, and when the screw is rotated at the speed of 100-1200 rpm, in the primary crushing section, the particle size is reduced to less than 1 mm. The obtained material is continuously passed through shear thinning section, so that graphite stripping is carried out and graphene-doped binder is formed. Shear thinning of the obtained material is continuously carried out through the dispersion orientation section, and stabilizer feed port is provided in the dispersion orientation section. A stabilizer is added to dispersed orientation section, and graphene along the rotation direction of the screw in the binder is evenly dispersed to obtain semi-conductive shielded graphene coating. An INDEPENDENT CLAIM is included for preparation of semi-conductive shielded graphene coating.
