NOVELTY - Preparing light composite graphene material involves taking 4-6 pts. wt. phosphorus tetramethylol sulfate, adding 15-20 times alcohol solution, increasing the temperature to 50-60 degrees C, keeping the temperature and stirring for 1-2 hours to obtain alcohol acyl phosphide solution, taking 10-14 pts. wt. light calcium carbonate and 2-3 pts. wt. zinc stearate, raising the temperature to 70-76 degrees C, adding to the phosphorus compound in the alcohol solution, keeping the temperature and stirring for 1-2 hours to obtain light alcohol solution, taking 0.3-1 pts. wt. 8-hydroxyquinoline into 10-12 times absolute ethyl alcohol and subjecting to 90-95 degrees C constant temperature water bath, and keeping the temperature and stirring for 30-40 minutes, discharging, adding 5-6 pts. wt. tetramethyl disiloxane, stirring to normal temperature to obtain alcohol solution, taking the solution, light alcohol solution, ultrasound for 3-5 minutes to obtain light alcohol solution. USE - Method for preparing light composite graphene material. ADVANTAGE - The method enables preparing light composite graphene material, which has good compatibility, reduces the weight of the finished polymer, improves processability, improves mechanical strength, and has good promoting effect. DETAILED DESCRIPTION - 25-30 pts. wt. Graphene is then added and mixed with 40-50 times mixed acid solution, temperature is raised to 60-65 degrees C for 2-3 hours, 3-4 pts. wt. potassium permanganate is then added, the temperature is then increased to 80-90 degrees C for 40-50 minutes, filtering, washing the precipitate, vacuum drying at 100-110 degrees C completely to obtain graphene oxide. The graphene oxide is then added to 30-49 times de-ionized water, followed by addition of 5-7 pts. wt. acrylic acid, and performing ultrasonic for 10-15 minutes to obtain the graphene oxide dispersion. The graphene oxide dispersion light alcohol solution is then taken, mixed, stirred uniformly, 0.1-0.2 pts. wt. platinum dioxide is added along with inletting nitrogen at a preserving temperature and reacted for 10-15 hours at 40-50 degrees C, filtered and washed the precipitate, dried at normal temperature to obtain the light composite graphene material.
