▎ 摘　　要

NOVELTY - Graphene composite material based eco-friendly bulb comprises a lampshade (1), a light-emitting diode (LED) lighting assembly (2), a metal sleeve (4) interfaced with the lampshade, a light source (5) and a base (6). A silicon carbide heat conductor (3) is equipped between the lampshade and the metal sleeve. The metal sleeve penetrates through multiple heat radiating holes (40). The silicon carbide heat conductor has multiple heat radiating grooves (31). A heat dissipation coating (30) is uniformly coated on the inner and outer surfaces of the silicon carbide heat conductor. USE - Graphene composite material based eco-friendly bulb. ADVANTAGE - The graphene composite material based eco-friendly bulb certain antibacterial effect has the function of repelling mosquitoes and ability to release negative ions without affecting the heat dissipation effect of the original lamps. The graphene composite material based eco-friendly bulb has certain function of removing formaldehyde, toluene, total volatile organic compounds and other pollutants. DETAILED DESCRIPTION - Graphene composite material based eco-friendly bulb comprises a lampshade (1), a light-emitting diode lighting assembly (2), a metal sleeve (4) interfaced with the lampshade, a light source (5) and a base (6). A silicon carbide heat conductor (3) is equipped between the lampshade and the metal sleeve. The metal sleeve penetrates through multiple heat radiating holes (40). The silicon carbide heat conductor has multiple heat radiating grooves (31). A heat dissipation coating (30) is uniformly coated on the inner and outer surfaces of the silicon carbide heat conductor. The heat-dissipating coating material is prepared by mixing the weighed amount of component such as 60-75 pts. wt. mixed resin, 5-6.5 pts. wt. graphene, 3-4.5 pts. wt. sodium montmorillonite, 4-6.5 pts. wt. carboxylated styrene-butadiene latex, 1.5-2 pts. wt. branched phenyl 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 fiber, 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 pts. wt. cerium oxide, 1.5-2 pts. wt. active mineral powder, 1.5-2.5 pts. wt. of traditional Chinese medicine essential oil.
