NOVELTY - Sodium silicate solution comprises graphene, water, and silicone compounds. USE - Used as sodium silicate solution. ADVANTAGE - The sodium silicate solution preparation is simple, and suitable for industrial production. DETAILED DESCRIPTION - Sodium silicate solution comprises graphene, water, and silicone compounds of formula (R2O-nSiO2) (I). An INDEPENDENT CLAIM is also included for the following preparing the sodium silicate solution comprising (i) drying and roasting the solid R2O-nSiO2, mixing graphene oxide solution and deionized water, stirring for 30 minutes, the stirring speed is less than or equal to 200 rotations/minute, (ii) adding the mixed solution obtained in step (i) into a sealed stirring reaction kettle, heating and pressurizing, (iii) extracting the mixed solution, settling to remove impurities, and adding the impurity-free portion of the liquid into the concentrating tank, concentrating to corresponding Baume degree to obtain the product. R2, n = not defined.
