▎ 摘  要

NOVELTY - Preparing modified graphene oxide involves taking proper amount of modified graphene oxide, preparing dispersion of 2 g/l graphene oxide, dispersing for 2 hours under the ultrasonic condition, weighing 1000 g of graphene oxide dispersion liquid, putting in the reaction kettle, stirring, heating in water bath at 70 degrees C, weighing the 4 g vinyl triethoxy silane, adding into the reaction kettle by dropping for 0.5 hours, continuously reacting for 1 hours after dropping, allowing to stand and cooling, ending the test. USE - Method for preparing modified graphene oxide. ADVANTAGE - The method effectively weakens the graphene oxide to the tackifying effect of the concrete, and improves the utilization rate of the graphene oxide. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a formulation for preparing water-reducing mother liquor by using modified graphene oxide, comprises 360 g of polycarboxylic acid monomer, 240 g of modified graphene oxide dispersion, 1.1 g of hydrogen peroxide, 80 g of A solution, 103.5 g of B solution, 35 g of neutralization solution and 180 g of water; and (2) a method for preparing modified graphene oxide and formulation, which involves using of using 360 g of polycarboxylic acid monomer, 240 g of modified graphene oxide dispersion, 1.1 g of hydrogen peroxide, 80 g of A solution, 103.5 g of B solution, 35 g of neutralization solution and 180 g of water.
