NOVELTY - Graphite powder is stirred in concentrated sulfuric acid, after adding sodium nitrate. Potassium permanganate is added and the contents are reacted. The temperature is raised to 80 degrees C and reacted. Deionized water and 30% hydrogen peroxide are added and the contents are reacted to obtain graphene oxide solution. Filler, defoaming agent, preservative, water reducer and graphene oxide solution are added into acrylic ester polymer emulsion, and stirred. Cement is added and the contents are stirred to obtain graphene oxide modified polymer-cement waterproof paint. USE - Manufacture of graphene oxide modified polymer cement waterproof paint (claimed). ADVANTAGE - The graphene oxide modified polymer cement waterproof paint has excellent mechanical property, and forms coating having excellent air permeability, durability, water resisting property, and increases the tensile strength and toughness of cement hydrated products. DETAILED DESCRIPTION - 5 Parts mass graphite powder is stirred in 50 parts mass concentrated sulfuric acid, after adding 5 parts mass sodium nitrate. The temperature of the system is controlled to less than 10 degrees C, and stirred uniformly. 18 Parts mass potassium permanganate is added and the contents are reacted for 9 hours at 35 degrees C. The temperature is raised to 80 degrees C and reacted for 1 hour. 600 Parts mass deionized water and 30% hydrogen peroxide are added and the contents are reacted. The reaction mixture is filtered, washed using 30% sodium hydroxide and ultrasonically treated to obtain graphene oxide solution. 106-352 parts mass filler, 3 parts mass defoaming agent, 3 parts mass preservative, 3 parts mass water reducer and 6-20 parts mass graphene oxide solution are added into 100-332 parts mass acrylic ester polymer emulsion, and stirred. 106-352 parts mass cement is added and the contents are stirred to obtain graphene oxide modified polymer-cement waterproof paint.
