DETAILED DESCRIPTION - A light-emitting diode lamp socket composition comprises 10 pts. wt. graphene microchip, 15 pts. wt. nano-alumina, 10 pts. wt. silica, 5 pts. wt. modified corn starch, 2 pts. wt. clay, 1.5 pts. wt. rosin soap, 10 pts. wt. modified purple powder, 2 pts. wt. tea alkaloids, 2.5 pts. wt. silicon nitride, 1.5 pts. wt. maifan powder, 2 pts. wt. expanded graphite powder, 2.5 pts. wt. sepiolite, 2 pts. wt. magnesite, 2 pts. wt. lignin, 2 pts. wt. wood-plastic powder and 2 pts. wt. silicon carbide fibers. The graphene microchip is three-dimensional crystal and is obtained by polishing carbon graphite crystal using nano-grinding mode. The modified corn starch comprises 80 pts. wt. corn starch, 5 pts. wt. hydroxypropyl-( beta )-cyclodextrin, 5 pts. wt. stearic acid, 3 pts. wt. alkaloids, 0.5 pts. wt. catechin, 0.5 pts. wt. defoaming agent, 2 pts. wt. polyester staple fiber, 2 pts. wt. lignosulfonate, 2 pts. wt. cyclohexanone, 1 pt. wt. antioxidant and 100 pts. wt. water. The modified corn starch is obtained by placing corn starch in oven, baking at 120 degrees C for 40 seconds, cooling to room temperature, placing in freezer at -6 degrees C for 24 hours, adding frozen material to stainless steel heating tank, adding hydroxypropyl-( beta )-cyclodextrin, stearic acid, alkaloid, catechin, defoaming agent, polyester staple fiber, sodium lignosulfonate, cyclohexanone, antioxidant and water, sealing the tank, heating, stirring at 90-165 degrees C and 120 rpm for 60-65 minutes, freezing at 0-2 degrees C for 24 hours, crystallizing, analyzing, placing in oven at 60 degrees C, drying such that moisture content is reduced to less than 10% and sieving using 120 mesh.
