NOVELTY - Preparation of oxidized graphene modified polymer cement waterproof coating involves mixing 50 pts. wt. concentrated sulfuric acid, 5 pts. wt. graphite powder and 5 pts. wt. sodium nitrate mixture, cooling at 10 degrees C, mixing, adding 16-20 pts. wt. potassium permanganate, reacting at 35 degrees C for 9 hours, heating to 80 degrees C for 1 hour, adding 600 pts. wt. deionized water and hydrogen peroxide, reacting, filtering, washing, adjusting pH to 7 using sodium hydroxide, ultrasonic treating for 2 hours, and mixing 106-352 pts. wt. filler, 1-3 pts. wt. defoamer and 1-3 pts. wt. preservatives. USE - Method for preparing oxidized graphene modified polymer cement waterproof coating (claimed). ADVANTAGE - The coating is durable, tough, and has high tensile strength and improved mechanical properties.
