▎ 摘  要

NOVELTY - Production of conductive glass fiber reinforced plastic article, involves preparing glass fiber containing silicon dioxide, aluminum oxide and calcium oxide, ultrasonically stirring glass fiber in graphene quantum dot dispersion solution, and soaking, adding graphene dispersion solution in glass fiber, coating release agent on mold, applying resin glue containing inorganic filler to mold surface, applying glass fiber layer, again applying resin glue to glass fiber layer, until the required thickness, curing and stripping, to obtain conductive glass steel product. USE - Production of conductive glass fiber reinforced plastic article (claimed). ADVANTAGE - The plastic article is obtained with excellent mechanical property, while effectively improving the electrical. DETAILED DESCRIPTION - Production of conductive glass fiber reinforced plastic article, involves pulverizing and mixing 50-55 wt.% silicon dioxide, 10-15 wt.% diboron trioxide, 0.1-0.5 wt.% disodium oxide, 10-15 wt.% aluminum oxide, 15-20 wt.% calcium oxide and 0.1-0.5 wt.% multi-walled carbon nanotube or porous graphene, placing the mixture in 400 mL corundum crucible and melting with silicon molybdenum rod furnace at 1370 degrees C and baking at 1200 degrees C, cast molding the mixture and annealing in the muffle furnace at 500 degrees C, to produce glass, heating the prepared glass at 1050 degrees C, and drawing into a glass fiber of 10 mu m in diameter, weighing the graphene quantum dots to prepare dispersion solution having concentration of 0.1-1 mg/ml with solvent which is water, acetone or dimethyl sulfoxide, ultrasonically stirring pretreated glass fiber in 80-100 ml graphene quantum dot dispersion solution, and soaking for 30-60 minutes, removing the glass fiber, cleaning and drying, preparing graphene dispersion solution having a concentration of 0.2-0.8 mg/ml with solvent which is water, acetone or dimethyl sulfoxide, adding 80-100 ml graphene dispersion solution in glass fiber and stirring for 10 minutes, and then moving the mixture to polytetrafluoroethylene kettle and maintaining the temperature at 80-120 degrees C for 15-30 minutes, remove the glass fiber, cleaning and drying, to obtain graphene modified glass fiber reinforced material, coating the release agent on the surface of the mold and drying, mixing 60-90 pts. wt. resin, 1-3 pts. wt. initiator, 120-230 pts. wt. inorganic filler and 3-8 pts. wt. carbon nanotube, to obtain a resin glue, applying the resin glue to the mold surface, then applying the glass fiber layer, again applying resin glue to glass fiber layer, and then forming glass fiber layer, until the required thickness, curing and stripping, to obtain conductive glass steel product.
