NOVELTY - Preparing radiating eye-protecting table lamp comprises preparing base, support, lampshade shell and lampshade cover plate respectively, then assembling base, support, lampshade shell, lampshade cover plate and LED lamp assembly to form table lamp, where base, support and lampshade shell are all formed by injection molding of graphene composite heat-conducting granules, where graphene composite heat-conducting granules is prepared by e.g. (i) adding graphene, graphite nano-sheets and heat-conducting fiber filler to first dispersion, uniformly mixing first dispersion with first dispersant and deionized water, stirring, and pre-dispersing, dispersing in homogenous or sand milling manner to obtain composite dispersion, and (ii) adding thermoplastic resin, plasticizing, adding composite dispersion to resin melt in the form of spraying, cutting and mixing, and dispersing composite dispersion in resin to obtain graphene composite thermal conductive granules USE - The method is useful for preparing radiating eye-protecting table lamp. ADVANTAGE - The table lamp: has improved radiating effect; has ability to absorb blue light; has improved illuminance and uniformity; and has anti-dizziness and better eye protection effects. DETAILED DESCRIPTION - Preparing radiating eye-protecting table lamp comprises preparing base, support, lampshade shell and lampshade cover plate respectively, then assembling base, support, lampshade shell, lampshade cover plate and LED lamp assembly to form a table lamp, where the base, support and lampshade shell are all formed by injection molding of graphene composite heat-conducting granules, where the graphene composite heat-conducting granules is prepared by: (i) adding 1-20 pts. wt. graphene, 1-30 pts. wt. graphite nano-sheets and 1-10 pts. wt. heat-conducting fiber filler to first dispersion, uniformly mixing the first dispersion with 1-5 pts. wt. first dispersant and 40-96 pts. wt. deionized water, stirring, and pre-dispersing for 10-30 minutes at high speed, then dispersing for 10-100 minutes in a homogenous or sand milling manner to obtain a composite dispersion after dispersion, and (ii) adding thermoplastic resin to twin-screw extruder, completely plasticizing the thermoplastic resin, adding composite dispersion to resin melt in the form of spraying, where the composite dispersion has 10-60 wt.% compared with the thermoplastic resin, then cutting and mixing by twin-screw extruder, uniformly dispersing composite dispersion in resin to obtain graphene composite thermal conductive granules after dispersion, where the lampshade cover plate comprises a graphene composite light reflection sheet, a graphene composite light guide sheet, and a graphene composite light diffusion sheet that are sequentially arranged from the inside to the outside, coating the graphene composite light reflection sheet, graphene composite light guide sheet, and graphene composite light diffusion sheet on different substrates by spin coating, dip coating, roll coating or spray coating with a graphene transparent dispersion liquid and then drying.
