NOVELTY - Preparing graphene oxide polycarboxylic acid series high performance water reducing agent comprises e.g. drying and slicing flexible graphite coil, immersing in vessel containing sulfuric acid solution, applying direct current of 1.6 volts for about 20 minutes to form flexible graphite roll into a low-order intercalated graphite continuous material, taking out continuous material of intercalated graphite and removing absorbed concentrated sulfuric acid, immersing in dilute sulfuric acid solution, electrolytic peeling to obtain graphite oxide, washing diluted sulfuric acid adsorbed on the graphite oxide with distilled water, performing ultrasonic dispersion treatment in water to obtain graphene oxide solution, mixing and diluting graphene oxide solution with water, stirring at 2500-3000 revolutions/minute, mixing with polycarboxylic acid high-performance water-reducing agent powder, stirring, and adjusting pH to neutral with sodium hydroxide. USE - The method is useful for preparing graphene oxide polycarboxylic acid series high performance water reducing agent. ADVANTAGE - The water reducing agent: can be reused, which avoids the risk of environmental pollution, and also saves production costs. The method eliminates ultrasonic dispersion equipment, which reduces the cost of the equipment. DETAILED DESCRIPTION - Preparing graphene oxide polycarboxylic acid series high performance water reducing agent comprises (i) under normal temperature, using flexible graphite coil as raw material, drying and slicing, completely immersing in a vessel containing a 98% concentrated sulfuric acid solution, using flexible graphite roll as anode, platinum wire as cathode, applying direct current of 1.6 volts for about 20 minutes to form flexible graphite roll into a low-order intercalated graphite continuous material, (ii) under normal temperature, taking out continuous material of intercalated graphite and removing absorbed concentrated sulfuric acid, completely immersing in a vessel containing 50% dilute sulfuric acid solution, using intercalated graphite continuous material as anode and platinum wire as the cathode, applying direct current of 5 volts to the electrolyte solution for electrolytic peeling for about 1 minute to obtain graphite oxide, (iii) washing diluted sulfuric acid adsorbed on the graphite oxide with distilled water, performing ultrasonic dispersion treatment in water to obtain a graphene oxide solution, and (iv) mixing and diluting graphene oxide solution with water, stirring at 2500-3000 revolutions/minute, mixing with polycarboxylic acid high-performance water-reducing agent powder, stirring, and adjusting pH to neutral with sodium hydroxide. An INDEPENDENT CLAIM is also included for graphene oxide polycarboxylic acid series high performance water reducing agent, prepared by above method.
