DETAILED DESCRIPTION - A graphene composite material based environmental protection bulb comprises a lamp shade, LED lighting components, a metal sleeve connected with the lamp shade, a power supply driver module, a base, and a silicon carbide thermal conductor arranged between the lamp shade and the metal sleeve. The metal sleeve is provided with heat radiating holes that penetrate through the metal sleeve. The silicon carbide thermal conductor is provided with a heat radiating groove, and a heat dissipation coating evenly coated on inner and outer surfaces of the silicon carbide thermal conductor. The LED lighting components and the silicon carbide thermal conductor are coated with heat dissipation coating. The heat dissipation coating is evenly coated on the inner surface of the metal sleeve. The heat dissipation coating includes 60-75 pts. wt. mixed resin, 5-6.5 pts. wt. graphene, 3-4.5 pts. wt. sodium montmorillonite, 4-6.5 pts. wt. carboxy styrene-butadiene latex, 1.5-2 pts. wt. silicone-branched methyl silicone oil, 0.7-1.2 pts. wt. polyethylene glycol, 0.7-1.8 pts. wt. n-pentane, 1-2.5 pts. wt. nano-silica, 7-9 pts. wt. polyacrylonitrile-based carbon fibers, 1-2 pts. wt. fumed silica, 5.5-7 pts. wt. flame retardant, 4-6 pts. wt. modified aromatic amine curing agent, 15-20 pts. wt. solvent, 0.1-0.15 pt. wt. cerium oxide, 1.5-2 pts. wt. active mineral powder, and 1.5-2.5 pts. wt. essential oil of traditional Chinese medicine. The mixed resin is a mixture of phenolic resin and epoxy resin in a mass ratio of 2:1 to 3:1. The polyacrylonitrile-based carbon fiber has a length of 0.01 mm. The flame retardant includes ammonium polyphosphate, melamine and expanded graphite in a mass ratio of 2:1.5:1.3. The solvent is diacetone alcohol and butyl ester in a mass ratio of 3:1 to 3:2. The active mineral powder is germanium stone, fluorite, tourmaline, and zinc spinel in a weight ratio of 2.5:3:3.5:1.7, and has a particle size of less than or equal to 15 mu m. The tourmaline is a mixture of magnesium tourmaline and lithium tourmaline in a weight ratio of 4:3. The heat dissipation coating is prepared by adding mixed resin, sodium montmorillonite, carboxy styrene-butadiene latex, silicone-branched methyl silicone oil, polyethylene glycol, n-pentane, nano silica, polyacrylonitrile-based carbon fibers, graphene, fumed silica, flame retardant and solvent in a mixer, mixing at 80 degrees C for 40 minutes under high speed stirring, taking out from the mixture to obtain a mixture (A), adding 70-80 pts. wt. agrimoniae herba, 15-18 pts. wt. cortex moutan, 20-25 pts. wt. Chinese Torreya seed, 15-20 pts. wt. lavender, 3-5 pts. wt. Anemone hupehensis, 3-5 pts. wt. Acorus calamus, 3-4 pts. wt. Salvia miltiorrhiza, 3-4 pts. wt. Polygonum hydropiper, and 5-8 pts. wt. impurities in a vacuum oven at -20 degrees C for 2-3 hours, pre-treating in a microwave dryer at a microwave power of 17 kw for 30-40 minutes, putting the pre-treated material into an ultrafine pulverizer and then pulverizing to obtain 60 mesh bulk drug powder, adding the drug powder to an extraction vessel of a supercritical carbon dioxide extraction apparatus, extracting at an extraction pressure of 28 MPa, an extraction temperature of 45 degrees C and carbon dioxide flow rate of 1100 l/hour for 2 hours to collect crude oil directly in the flask at the outlet of the separation kettle, freezing the crude oil at 5 degrees C for 70 minutes, centrifuging the frozen crude oil in a high-speed refrigerated centrifuge at a speed of 17000 rpm for 25 minutes, evacuating at 85 degrees C for 3 hours in a vacuum box to remove impurities to obtain volatile oil (B), washing 1-3 pts. wt. Rhododendron molle, 1-3 pts. wt. large-headed Atractylodes rhizome, 1.5-2.5 pts. wt. sweet marjoram, 3-4 pts. wt. purslane, 3-4 pts. wt. Agastache rugosa, 3-4 pts. wt. Stellera chamaejasme and 3-4 pts. wt. Chinese mugwort, drying, crushing into an ultrafine mill through 30 mesh, immersing in deionized water for 5 hours, and stirring thoroughly to obtain the traditional Chinese medicine mixture, decanting the traditional Chinese medicine mixture for 2 hours at 80 degrees C to obtain distillate, extracting the distillate with diethyl ether, where the volume ratio of distillate to diethyl ether is 2.5:1, adding 0.13-0.2 pt. wt. anhydrous sodium sulfate for drying treatment to obtain volatile oil (C), mixing the volatile oil (B) and the volatile oil (C) to obtain a mixed oil, mixing the mixed oil with wheatgerm essential oil, geranium essential oil, snow lotus oil, lemon essential oil and grapefruit essential oil, stirring for 45 minutes, allowing to stand for 30 minutes, filtering impurities to obtain Chinese medicine essential oils, where the mass ratio of the mixed oil to wheat germ essential oil, geranium essential oil, snow lotus oil, lemon essential oil and grapefruit essential oil is 2:0.5:0.5:0.6:0.4:0.5, mixing the crude essential oil and the mixture (A) at 70-80 degrees C, concentrating for 15 minutes to obtain a premix, adding the premix into a ball mill, adding cerium oxide, active mineral powder and modified aromatic amine curing agent, concentrating the mixture for 4.5 hours at 70-80 degrees C, and filtering to remove impurities.
