NOVELTY - Preparing high solid content of graphene oxide grafted polyacrylate composite liquid, comprises adding graphene oxide, thionyl chloride and N,N-dimethylformamide into three neck bottle, then processing, rotary evaporating the mixture, adding triethylamine and ethyl acrylate to the mixture, adding sodium dodecyl sulfate and distilled water to the black powder solution, adding double bond of graphene oxide, sodium dodecyl sulfate and distilled water into the three neck bottle, dripping methyl methacrylate, butyl acrylate, initiator, ammonium persulfate and distilled water, and discharging. USE - The method is useful for preparing high solid content of graphene oxide grafted polyacrylate composite liquid (claimed). ADVANTAGE - The method is capable of preparing the high solid content of graphene oxide grafted polyacrylate composite liquid with high film-forming solid content, breaking strength, breaking elongation rate and high water absorption rate. DETAILED DESCRIPTION - Preparing high solid content of graphene oxide grafted polyacrylate composite liquid, comprises adding 0.2-0.5 pts. wt. graphene oxide, 25-40 pts. wt. thionyl chloride and 0.5-0.8 pts. wt. N,N-dimethylformamide into 100 ml three neck bottle, then ultrasonically processing for 30-90 minutes, raising the temperature to 50-80 degrees C for 24-48 hours under reflux device and nitrogen, cooling to room temperature, then adding 20-26 pts. wt. N,N-dimethylformamide, rotary evaporating the mixture at 40-55 degrees C for 2 hours, adding 0.10-0.25 pts. wt. triethylamine and 0.15-0.30 pts. wt. ethyl acrylate to the mixture, stirring the mixture at normal temperature for 6-12 hours, standing in overnight, removing supernatant, then adding 500 pts. wt. distilled water and filtering, washing solid sample using distilled water to obtain a black powder solution, adding 0.2-0.5 pts. wt. sodium dodecyl sulfate and 20-50 pts. wt. distilled water to the black powder solution, ultrasonically processing for 10-40 minutes, and freezing and drying the mixture to obtain a double bond of graphene oxide, adding obtained 0.01-0.04 pts. wt. double bond of graphene oxide, 2-3.5 pts. wt. sodium dodecyl sulfate and 24-34 pts. wt. distilled water into the 100 ml three neck bottle, uniformly mixing and stirring the mixture, then ultrasonically processing fro 15-30 minutes, raising the temperature to 75-80 degrees C, mixing 0.1-0.4 pts. wt. ammonium persulfate and 2.3-9 pts. wt. distilled water to obtain a mixed liquid, stirring the mixed liquid for 10 minutes, dripping 0.6-2.4 pts. wt. methyl methacrylate, 4-10 pts. wt. butyl acrylate, 10-18 pts. wt. initiator solution, 0.1-0.4 pts. wt. ammonium persulfate and 2.3-9 pts. wt. distilled water for 60-120 minutes, keeping the temperature for 60 minutes, and discharging the material.
